Answer:
85 degrees
Step-by-step explanation:
How many different 4-digit numbers can be created if no digit can be
repeated? Remember, a number cannot begin with 0.
Answer:
2
Step-by-step explanation:
1234
4567
Explanation:
There are ten single digit values 0 through 9. But we cannot use 0 as the first digit, so we have 9 possible choices for the first slot.
For the second slot, we also have 9 choices because we can now pick 0.
The third slot has 8 choices.
The last slot has 7 choices.
Each time we form a new slot, the number of choices drops by 1. The exception of course is the jump from the first to second slot.
Overall, there are 9*9*8*7 = 4536 different numbers.
i need to know the rest of the equation just letter R
Notice that 2/3 times 12 is...
(2/3)*12 = (2/3)*(12/1)
(2/3)*12 = (2*12)/(3*1)
(2/3)*12 = 24/3
(2/3)*12 = 8
So that explains the 8 on the right hand side.
For the blank, we'll multiply 2/3 by the 9y term like so
(2/3)*9y = ((2/3)*(9/1))y
(2/3)*9y = ((2*9)/(3*1))y
(2/3)*9y = (18/3)y
(2/3)*9y = 6y
This means 6y goes in the blank.
If your teacher only cares about the coefficient, aka number out front of the variable, then you'd just go for 6. That's my guess as to what your teacher wants. It seems to fit with the template you show and that would mean R goes in the second to last slot.

Find the additive inverse of each number: 7/10 and -0.6
Answer:
additive inverse of 7/10 is -7/10 and 0.6 is 0.6
Step-by-step explanation:
Additive inverse simply means changing the sign of the number and adding it to the original number to get an answer equal to 0. The properties of additive inverse are given below, based on the negation of the original number. For example, if x is the original number, then its additive inverse is -x.

A parabola with no real zeros, a negative leading coefficient, and an odd y-intercept.
pls help!
Answer:
Step-by-step explanation:
A parabolic graph with no real zeros never touches or crosses the x-axis.
If the leading coefficient is negative, that tells us that the parabola opens down (and, in this case, that the entire graph is below the x-axis, because there are no real zeros.
If the y-intercept is odd, then the constant term, c, in ax^2 + bx + c, must be a negative, odd integer.
Suppose we say that the vertex of a particular parabola that is described by the above is (-2, -1) and that the y-intercept is -3. (Note: this is strictly an example.) Then the vertex equation of this parabola is obtained from the general vertex equation of a parabola,
y = a(x - h)^2 + k. Here h = -2 and k = -1, and so the particular parabola is
y = -a(x + 2)^2 - 1, where a is a constant and -a is negative.
In general form, this would be y = -a(x^2 + 4x + 4) - 1, or
y = -ax^2 - 4ax - 4a -1
and the constant terem (-4a -1) must be an odd negative integer
This is only one of an infinite number of possible equations for the parabola described above.

Answer:
A
Step-by-step explanation:
We can solve for H by isolating it on one side of the equation, as follows:
J/H - I/H = G
Taking H as the common denominator:
(J - I)/H = G
Multiplying both sides by H:
J - I = GH
Adding I to both sides:
J = GH + I
Dividing both sides by G:
H = (J - I)/G
So the answer is
(A)
H = (J - I)/G.
Answer: A
Step-by-step explanation:
\(\frac{J}{H} = G + \frac{I}{H}\) >Since you are solving for H bring I/H to the other side
by subtracting I/H from both sides
\(\frac{J}{H}- \frac{I}{H} = G\) >There is a common denominator so you can
combine the fractions
\(\frac{J-I}{H} = G\) >Multiply both sides by H or cross multiply whichever
way your mind things about how to get H on top
\(J-I = G(H)\) >Divide both sides by G
\(\frac{J-I}{G} = H\) >Answer is A

A restaurant sells burritos for $8.00 each. The cost of the meat is $1.50 and the cost of other ingredients is $1.00 for each burrito.
4.What is the profit the restaurant makes from selling 100 burritos? Does the restaurant make money or lose money? Explain
Answer:
550$ profit
The restaurant makes money (explained at the bottom.)
Step-by-step explanation:
In order to get rid of the potential loss and make it easier to calculate we are going to remove the cost of the meat and other ingredients from our calculations.
(8$-1.5$-1$) x (x)
That leaves us with 5.5$ per burrito (post manufacturing price), so that we can calculate raw profit.
(5.5$)(x)
We are now going to replace x with 100 so that we can determine how much money we gain from 100 burritos in total sold at 5.5$ per burrito.
(5.5$)(100) = 550$
(pre-tax)
The price of selling the burrito is more than the cost of the manufacturing of it, therefore they would be making money on every burrito sold, 5.5$ to be exact.

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

1) Each lunch for a school field trip has a turkey, roast beef, or bologna sandwich, an orange or apple for a fruit, and a cookie or muffin for dessert. Amanda and Zack would like to…
-know the number of possible lunch options.
-P of having any meal with NO COOKIE.
(use sample space, tree diagram, and counting principle)
1) there are 12 possible lunch options. 2) the probability of having any meal with no cookie is 1/2 or 0.5.
How to find the number of possible lunch options.1) Number of possible lunch options:
To determine the number of possible lunch options, we need to consider the choices for each component of the lunch.
- Sandwich: There are 3 options (turkey, roast beef, or bologna).
- Fruit: There are 2 options (orange or apple).
- Dessert: There are 2 options (cookie or muffin).
Using the counting principle, we multiply the number of options for each component together:
Number of possible lunch options = 3 (sandwich options) × 2 (fruit options) × 2 (dessert options) = 12.
Therefore, there are 12 possible lunch options.
2) Let's examine the favorable outcomes for each component:
- Sandwich: There are still 3 options (turkey, roast beef, or bologna).
- Fruit: There are 2 options (orange or apple).
- Dessert: There is 1 option (muffin, as we want to exclude cookies).
Using the counting principle, we multiply the number of options for each component together:
Number of favorable outcomes (no cookie) = 3 (sandwich options) × 2 (fruit options) × 1 (muffin option) = 6.
The total number of possible outcomes is still 12 (as calculated in the previous step).
Therefore, the probability of having any meal with no cookie is:
P(No cookie) = Number of favorable outcomes / Total number of possible outcomes = 6 / 12 = 1/2 or 0.5.
Hence, the probability of having any meal with no cookie is 1/2 or 0.5.

Step-by-step explanation:
the ratio of the number of oranges to apples to bananas is 8:5:2. if there are 120 fruits in total, how many bananas are there
Answer:
Step-by-step explanation:
To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.
Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.
The sum of the parts in the ratio is 8x + 5x + 2x = 15x.
We know that the total number of fruits is 120. Therefore, we can set up the following equation:
15x = 120
To solve for x, we divide both sides of the equation by 15:
x = 120 / 15
x = 8
Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:
Number of bananas = 2x = 2 * 8 = 16
So, there are 16 bananas in total.
We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.
