The largest number of weights Jennifer could own is 798.
When do we use multiplication?Repeated addition of the same number is made easier by multiplying the numbers. When we need to merge groups of similar sizes, we employ it. For instance, if there are 5 baskets, each containing 4 apples, we can use multiplication to get the total number of apples, which is 5 x 4 = 20 apples.
We can rapidly determine the total number of things by multiplying. When multiplying, we'll consider the number of groups with similar sizes and the number of items in each group.
Given: The collection of weights : 4 , 6 and 9 pounds
The total weight of the weights = 42 pounds
Thus the largest number of weights jennifer could own is 4+6+9 = 19 multiplied by the total weight of the weights
= 19 × 42
= 798.

Custard is heated to a temperature of 180°F. It is then allowed to cool in a refrigerator whose temperature is 30°F. The custard cools to 120°F in 30 minutes. Determine how long will it take for the custard to cool to 50°F.
Answer: About 65 minutes.
It changes an average of about 60 degrees Fahrenheit every half hour.
180 120 60 50
0 30 60 65
Now it is about ten degrees until it's fifty. Since it takes thirty minutes to go down sixty degrees, divide sixty by ten to get six. Then divide thirty by six to get five. So, it should take about 65 minutes to cool down to 50 degrees.
It will take approximately 35 minutes for the custard to cool from 120°F to 50°F.
To determine how long it will take for the custard to cool to 50°F, we need to consider the rate at which it cools. From the given information, we know that the custard cools from 180°F to 120°F in 30 minutes.
To find the rate of cooling, we can calculate the temperature change per minute.
The temperature decreases by 180°F - 120°F = 60°F over 30 minutes. So, the rate of cooling is 60°F / 30 minutes = 2°F per minute. Now, let's use this rate to calculate how long it will take for the custard to cool from 120°F to 50°F.
The temperature difference between 120°F and 50°F is 120°F - 50°F = 70°F. To cool from 120°F to 50°F at a rate of 2°F per minute, it will take 70°F / 2°F per minute = 35 minutes.

The ordered pair for A' is (5, -3).The ordered pair for B' is (-2, 7).The ordered pair for C' is (8, 8).The ordered pair for D' is (10, 4).What is a rotation?A rotation is a type of transformation which moves every point of the object through a number of degrees around a given point, which can either be clockwise or counterclockwise direction.
In Mathematics, rotating a point 90° about the origin in a clockwise or counterclockwise direction would produce a point that has the coordinates (y, -x).
By applying a rotation of 90° clockwise to square ABCD, the coordinate of the image of square A'B'C'D' is given by:
(x, y) → (y, -x)
Points at A = (-3, 5) → Points at A' = (5, -(3)) = (5, -3)
Points at B = (-7, -2) → Points at B' = ((-2), -(-7)) = (-2, 7).
Points at C = (-8, 8) → Points at C' = (8, -(-8)) = (8, 8).

a function is said to have a horizontal asymptote if either the limit at infinity exists or the limit at negative infinity exists. show that each of the following functions has a horizontal asymptote by calculating the given limit.
A function can only have two horizontal asymptotes, hence the answer is no. By examining the degrees of the numerator and denominator, one can find the horizontal asymptote of a rational function.
If limxf(x)=L or limxf(x)=L, a function f(x) will have the horizontal asymptote y=L. Therefore, we simply calculate the function's limit as it approaches infinity and again as it approaches negative infinity to locate horizontal asymptotes. Based on the degree of the numerator, n, and the degree of the denominator, m, horizontal asymptotes adhere to three principles. The horizontal asymptote is y = 0 if n m. The horizontal asymptote is y = a/b if n = m. There is no horizontal asymptote if n > m. As x gets closer to 0, we say that f(xlimit )'s is infinite. A boundary or a limit is now a number.

In ΔTUV, UV = 14, VT = 19, and TU = 9, The statement about the angles of ΔTUV that must be true is [tex]m \angle U > m \angle T > \angle V[/tex] Option 5
This is further explained below.
What are angles?Generally, A triangle's angle is a measurement of the length of the side that is perpendicular to it.
This indicates that if one of the sides is longer in length, then the measure of the angle opposite to it will also be longer.
The angles in the triangle TUV are denoted by the symbols T, U, and V.
The side that is UV, TV, and T U correspondingly is the side that is opposite to these angles.
The length of the opposing sides will immediately determine the measure of the angles, which will be directly proportionate to those angles.
since V T>U V>T U, the arrangement of angles will correspond to this as follows: [tex]m \angle U > m \angle T > \angle V[/tex] Option 5

Riley and Paul go to the driving range. Together, they hit 75 balls. Riley hit 17 more than Paul. How many
balls did each of them hit?
Riley hit 46 balls and Paul hit 29 balls at the driving range.
According to the question, let
Number of balls hit by Riley be x
Number of balls hit by Paul be y
Together Riley and Paul hit 75 balls
∴x+y=75 (1)
Riley hit 17 more balls than Paul
∴x= y + 17 (2)
Now we have to solve these simultaneous linear equations (1) and (2)
Replacing the value of x from equation (2) into equation (1) we get,
y+17+y=75
⇒2y + 17 = 75
⇒2y = 75 - 17
⇒2y = 58
⇒y = 58/2 (dividing both sides by 2)
⇒y = 29
∴No. of balls hit by Riley = x = y +17 = 29 + 17 = 46 (from equation (2))
Therefore, Riley hit 46 balls and Paul hit 29 balls at the driving range.
