There are 16 tablespoons in 1 cup. How many tablespoons of cornstarch would Cheryl need to make the green slime recipe 15 times?
Cheryl would need 240 tablespoons of cornstarch to make the green slime recipe 15 times.
What is multiplication?The fundamental concept of repeatedly adding the same number is represented by the process of multiplication. The results of multiplying two or more numbers are known as the product of those numbers, and the components that are multiplied are referred to as the factors.
To make the green slime recipe 15 times, Cheryl would need 15 times the amount of cornstarch listed in the recipe.
If 1 cup of cornstarch is needed for one recipe, then 15 cups of cornstarch would be needed to make the recipe 15 times.
Since there are 16 tablespoons in 1 cup, the number of tablespoons of cornstarch needed to make the recipe 15 times is:
= 16 tablespoons/cup x 15 cups
= 240 tablespoons.
So, Cheryl would need 240 tablespoons of cornstarch to make the green slime recipe 15 times.

The table shows the dimensions and the numbers of blades of grass on four rectangular pieces of sod. Select and drag the pieces of sod in order from greatest to least grass density, with greatest at the top and least at the bottom.
===============================================
Explanation:
Rectangle A has area 4*3 = 12 square feet. Divide the number of blades of grass over this area to get a density of 34188/12 = 2849. So the density for rectangle A is 2849 blades per square foot. Put another way, one square foot of rectangle A contains about 2849 blades of grass.Rectangle B has area 5*4 = 20 square feet and density 56340/20 = 2817 blades per square foot.Rectangle C has area 6*3 = 18 square feet and density 52632/18 = 2924 blades per square foot.Rectangle D has area 4*2 = 8 square feet and density 25248/8 = 3156 blades per square foot.The density order from greatest to least is therefore: D, C, A, B
Main Street and Washington Avenue meet at a right angle. A large park begins at this corner. Joe's school lies at the opposite corner of the park. Usually, Joe walks 3.6 miles along Main Street and then 1.5 miles up Washington Avenue to get to school. Today he walked in a straight path across the park and returned home along the same path. What is the difference in distance between the two round trips?
Complete the explanation and enter your answers rounded to the nearest tenth of a mile.
The difference in distance between the two round trips 2.4 miles.
The length of the line segment connecting the two sites is used to measure distance between them. The shortest line segment between a point and a line will have a length equal to the distance between them.
The x-coordinate, often known as the abscissa, is a point's separation from the y-axis.
Now, total joe walked the distance is
\(\sqrt{3.6^{2}+1.5^{2} }\)=3.9 miles
and on the daily basis he usually walks
3.6+1.5=5.1 miles
So, the difference in the distance in first trip
5.1-3.9=1.2 miles
and thus the difference in the distance in two round trips will be
1.2×2=2.4 miles.

Answer:
31°
Step-by-step explanation:
<Y + <X = 180° [being co-interior angles ]
s + 91° + 2s - 4° = 180°
3s + 87° = 180°
3s = 180° - 87°
3s = 93°
s = 93° /3
s = 31°
Hope it will help you :)❤
Answer:
\(\displaystyle 31\)
Step-by-step explanation:
Angles Y and X form a linear pair, therefore you use the Linear Pair Theorem to solve for x:
\(\displaystyle 180° = [2s - 4]° + [s + 91]° → 180° = [87 + 3s]° → 93 = 3s; 31 = s\)

Step-by-step explanation:
The body reverses direction whenever we go from Positve velocity to negative velocity or vice versa.
So here it is (2,7) exclusive then (7,10) exclusive.
A constant speed means a slope of 0. Here it is (3,6).
c. Since speed is non negative, we would reflect any part of the velocity function that is below the time.axis about the time axis
So we would get
Above is the function, don't worry bout the math part.
D. Knowing that acceleration is the derivative of velocity with respect to time, the derivative of any linear function is the slope of that linear function. So if we find the slope of different paths, we will get a constant and then we can graph it
We must use the original graph because acceleration is a vector meaning it can be negative.
We would get
the second graph is acceleration vs time

Blake is going to invest in an account paying an interest rate of 1.5% compounded quarterly. How much would Blake need to invest to the nearest dollar, for the value of the account to reach $910 in 10 years
Answer:
$783.46
Step-by-step explanation:
Compounded interest rate (quarterly) formula: A = P(1 + r/4)^4t
Simply plug in our known variables and solve:
910 = P(1 + 0.015/4)^4(10)
910 = P(1.00375)^40
910 = 1.16151P

I put some counters into groups with the same number in each group. I can’t remember what I did, but I do remember that I had 12 counters. What might the groups have been?
Answer:
6 groups of 2, 4 groups of 3, 3 groups of 4, 2 groups of 6, and 1 group of 12 or 12 groups of 1.
Step-by-step explanation:
This question requires you to factor 12. This is because you need to find the numbers that multiply to 12, or its factors. After factoring, you get 1, 2, 3, 4, 6, and 12. When you use these numbers as the amount of groups, you can divide 12 by them to get the size of the groups.

Certainly! The problem can be solved using the Pythagorean theorem,
which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
In this case, the ladder acts as the hypotenuse, and we need to find the length of the vertical side (height) it reaches up the wall.
The ladder forms the hypotenuse, and its length is given as 12 meters. The distance from the foot of the ladder to the base of the wall represents one side of the triangle, which is 4.5 meters.
By substituting the given values into the Pythagorean theorem equation: (12m)^2 = h^2 + (4.5m)^2, we can solve for the unknown height 'h'.
Squaring 12m gives us 144m^2, and squaring 4.5m yields 20.25m^2. By subtracting 20.25m^2 from both sides of the equation, we isolate 'h^2'.
We then take the square root of both sides to find 'h'. The square root of 123.75m^2 is approximately 11.12m.
Therefore, the ladder reaches a height of approximately 11.12 meters up the wall.

The probability that she will make a basket on or before her last attempt within her average waiting time are 1/8 and 2/8
How can we interpret probability?Probability of an event is a measurement of how likely an event can occur as an outcome of a random experiment;
Probability ranges from 0 to 1, both inclusive. Events whose probability is closer to 0 are rarer to occur than those whose probabilities are closer to 1 (relatively);
When converted to percentage, we just need to multiply its decimal representation by 100. In percentage form, the probability ranges from 0% to 100%;
Given:
Hannah makes 5 out of 8 attempted free-throws.
Now,
The average waiting time of hannah to make her first basket is 5/8
The probability of hannah making basket at her last attempt is 1/8
The probability of hannah making basket before her last attempt is 2/8

write and equation for the nth term of the geometric sequence for 2,8,32,128
then find a6 round to the nearest tenth if necessary.
The sixth term of the geometric sequence is 2048.
The given geometric sequence is 2, 8, 32, 128. We can observe that each term is obtained by multiplying the previous term by 4. Therefore, the common ratio (r) of the sequence is 4.
The formula for the nth term (an) of a geometric sequence is given by:
an = a1 * r^(n-1)
where a1 is the first term and r is the common ratio.
For this sequence, a1 = 2 and r = 4. Plugging in these values into the formula, we get:
an = 2 * 4^(n-1)
To find a6, we substitute n = 6 into the formula:
a6 = 2 * 4^(6-1)
= 2 * 4^5
= 2 * 1024

The transformation in this problem is a translation combined with a reflection, hence yes, it is a rigid motion, as the side lengths of the transformed figure are equal to the side lengths of the original figure.
What are transformations on the graph of a function?Examples of transformations are given as follows:
Translation: Translation left/right or down/up.Reflections: Over one of the axes or over a line.Rotations: Over a degree measure.Dilation: Coordinates of the vertices of the original figure are multiplied by the scale factor.The dilation is the only transformation that is not a rigid motion, as it changes the side lengths of the figure.
The transformation for this problem has the rule defined as follows:
(x,y) -> (x + 2, -y).
The transformations are defined as follows:
x -> x + 2 is a translation right two units.y -> -y is a reflection over the x-axis.Neither transformation is a dilation, hence it is a rigid motion.
