A restaurant sells 10 tacos for $8.49, or 6 of the same kind of taco for $5.40.
Which is the better deal?
Explain how you know in 3 sentences.TO GET BRAINLYEST
Answer:
6 tacos for $5.40 is the better deal
Step-by-step explanation:
To get the cost for 1 taco, I divided the quantity by the cost. I divided 10 / $8.49, and got $1.18. I divided 6 / $5.40 and got $1.11. The 6 tacos for $5.40 is the better deal because the cost of 1 taco is less than than the other.
Answer:
10 tacos for $8.49
Step-by-step explanation:
If you divide $8.49 by ten, each taco costs $0.85. If you divide $5.40 by six, each taco costs $0.90. The 10 for $8.49 deal is better.

You would like to have $20,000 to use a down payment for a home in five years by making regular, end-of-month deposits into an annuity that pays 6% interest compounded monthly.
How much should you deposit each month?
Round your answer to the nearest cent. Do not include the dollar sign in the answer box below.
The calculation of this can be done by first determining the future value of the monthly payments of $327.50
The future value of an annuity can be determined using a financial calculator, mathematical formula, or spreadsheet software. The future value of an annuity is calculated by multiplying the periodic payment amount by the future value factor,
which is based on the number of payments and the interest rate.For example, suppose we want to know the future value of a $500 end-of-month deposit into an annuity that pays 6% interest compounded monthly for five years.
The future value factor for 60 periods at 0.5 percent per month is 80.9747, which can be multiplied by the monthly deposit amount to find the future value of the annuity.500 × 80.9747 = 40,487.35
This means that a $500 end-of-month deposit into an annuity paying 6% interest compounded monthly for five years will have a future value of $40,487.35.
Therefore, to accumulate a $20,000 down payment for a home in five years, you would need to deposit $327.50 per month into the annuity.
for 60 months using the formula and then solving for the monthly payment amount where FV = $20,000 and n = 60, r = 0.5%.FV = PMT [(1 + r)n – 1] / r$20,000 = PMT [(1 + 0.005)60 – 1] / 0.005PMT = $327.50 (rounded to the nearest cent).

Olga is using spherical beads to create a border on a picture frame. Each bead has a diameter of 1.5 millimeters. Find the volume of each bead. Round to the nearest tenth.
The Volume of each bead is approximately 1.767 mm^3 when rounded to the nearest tenth.
The volume of each bead, the volume of a sphere using its diameter. The formula for the volume of a sphere is given by:
V = (4/3) * π * r^3
where V is the volume and r is the radius of the sphere.
Given that the diameter of each bead is 1.5 millimeters, we can calculate the radius as half of the diameter:
r = 1.5 mm / 2 = 0.75 mm
Now, we can substitute the value of the radius into the volume formula:
V = (4/3) * π * (0.75 mm)^3
Using the value of π ≈ 3.14 and performing the calculations:
V ≈ (4/3) * 3.14 * (0.75 mm)^3
V ≈ (4/3) * 3.14 * 0.421875 mm^3
V ≈ 1.767 mm^3 (rounded to the nearest tenth)

Step-by-step explanation:
C is the correct answer as both triangles have a similar angle of 105⁰ and both side lengths of triangle ABC are being divided by 4 to have the same two side lengths as triangle DEF
The triangles ΔABC and ΔDEF are similar triangles by SAS theorem
What are similar triangles?If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.
Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides
Given data ,
Let the first triangle be ΔABC
The measure of side AB = 16
The measure of side AC = 36
And , the measure of ∠ABC = 105°
Let the first triangle be ΔDEF
The measure of side DE = 16
The measure of side DF = 36
And , the measure of ∠DEF = 105°
Now , the ratio of sides of the triangles is given by
AB / DE = AC / DF
4/16 = 9/36
1/4 = 1/4
So , corresponding sides of similar triangles are in the same ratio
And , the measure of angles = 105°
Therefore , by SAS , Two sides are equal and the angle between the two sides is equal (SAS: side, angle, side)
Hence , they are similar triangles

Kay loves to save coins. She has a piggy bank that she has been filling for a long time with only dimes and nickels. Recently, her piggy bank was filled to the brim so Kay counted her coins and she discovered that she had $10. She also noticed that she has 11 less dimes than nickels. How many coins were in Kay's bank?
The total number of coins that were in Kay's bank are 137 coins.
How to determine the number of coins?In order to determine the number of dimes and nickels, we would assign a variables to the unknown numbers and then translate the word problem into algebraic equation as follows:
Let d represent the number of dimes.Let n represent number of nickels.Since she has 11 less dimes than nickels, an equation which models this situation is given by;
n = d + 11 ....equation 1.
Note: 1 nickel is equal to 0.05 dollar and 1 dime is equal to 0.1 dollar.
Additionally, the coins are worth 10 dollars;
0.1d + 0.05n = 10 ....equation 2.
By solving both equations simultaneously, we have:
0.1d + 0.05(d + 11) = 10
0.1d + 0.05d + 0.55 = 10
0.15d = 9.45
d = 63 dimes.
For nickels, we have:
n = d + 11
n = 63 + 11
n = 74
Now, we can determine the total number of coins;
Total number of coins = n + d
Total number of coins = 74 + 63
Total number of coins = 137 coins.

Mr. and Mrs. Doran have a genetic history such that the probability that a child being born to them with a certain trait is 3/4. If they have seven children, what is the probability that exactly three of their seven children will have that trait? Round your answer to the nearest thousandth.
The probability that exactly three of their seven children will have the given trait is 0.073.
To solve this problem, we can use the binomial probability formula. The probability of exactly k successes in n trials, where the probability of success is p, is given by:
P(X = k) = C(n, k) . \(p^k\) . (1 - \(p)^(n - k)\)
In this case, the probability of a child having the trait is p = 3/4, and we want to find the probability of exactly 3 children having the trait out of 7 children, so k = 3 and n = 7.
Using the formula:
P(3) = 7! / 4! 3! x (3/4)³ x (1-3/4)⁴
P(3) = 35 x 27/64 x 1/256
P(3) ≈ 0.073
Therefore, the probability that exactly three of their seven children will have the given trait is 0.073.

The thermochemical equation that corresponds to the given energy diagram is option C: A + 2B → AB₂ + Energy.
In the energy diagram, the reactants A and 2B have a higher energy level compared to the product AB₂. This indicates an exothermic reaction where energy is released during the formation of AB₂.
The downward slope in the diagram represents the energy change from the initial state to the final state.
Option A, A + 2B → AB with AH = +Energy, suggests that energy is absorbed during the reaction, which contradicts the energy diagram. Therefore, option A can be ruled out.
Option B, Energy + A + 2B → AB₂, does not provide information about the direction of the reaction or the energy change associated with it. It does not match the energy diagram, so option B can be eliminated as well.
Option C, A + 2B → AB₂ + Energy, aligns with the energy diagram. It indicates that energy is released as the reactants A and 2B combine to form the product AB₂. The energy released is represented by the downward slope in the diagram.
Therefore, the correct thermochemical equation corresponding to the graph is option C: A + 2B → AB₂ + Energy.

The 5-lb collar slides on the smooth rod, so that when it is at A it has a speed of 10 ft/s. A) if the spring to which it is at- tached has an unstretched length of 3 ft and a stiffness of k-= 10 lb/ etermine the normal force on the collar at this instant. B)Determine the acceleration of the collar at this instant.
The acceleration of the collar at point A is 5 ft/s^2.
A) To determine the normal force on the collar at point A, we need to consider the forces acting on the collar. The only force acting on the collar in the vertical direction is the weight of the collar (5 lb), which is balanced by the normal force exerted by the rod. Therefore, we can write:
N - 5 = 0
where N is the normal force. Solving for N, we get:
N = 5 lb
B) To determine the acceleration of the collar at point A, we need to use Newton's second law, which states that the net force acting on an object is equal to its mass times its acceleration. The net force on the collar is given by the force exerted by the spring, which is equal to the spring constant times the displacement of the collar from its unstretched length. At point A, the displacement of the collar is:
x = L - y = 3 - 0 = 3 ft
where L is the length of the rod and y is the position of the collar on the rod. Therefore, the force exerted by the spring is:
F = kx = 10 lb/ft × 3 ft = 30 lb
The weight of the collar is:
W = mg = 5 lb
where g is the acceleration due to gravity. The net force on the collar is therefore:
Fnet = F - W = 30 - 5 = 25 lb
Using Newton's second law, we can write:
Fnet = ma
where a is the acceleration of the collar. Solving for a, we get:
a = Fnet / m = 25 lb / 5 lb = 5 ft/s^2
Therefore, the acceleration of the collar at point A is 5 ft/s^2.

Peter had 208 Canadian stamps and 186 Mexican stamps for sale. The stamps were mixed up and sold in packets of 6. How many packets of stamps were there? How many stamps were left over?
Answer:
65 packets and 4 stamps
Step-by-step explanation:
The first thing we see is that the stamps are mixed... which means they must be added.
208 + 186 = 394 stamps total
Now we see that each packet has 6 stamps. So we divide the number of stamps in total by 6.
394/6= 65.66667
Now we see from that number that the stamps can't quite make 66 packets, so there are 65 packets.
Now we find the number of stamps left over by multiplying the number of packets by 6.
65 x 6= 390
Now we take the total number of stamps minus the number of stamps in packets.
394 - 390 = 4
Therefore, there are four stamps left over.
