than angle PQS.
What is the measure of angle SQT?
Answe70
Step-by-step explanation:
The measure of the angle SQT will be 70°. The correct option is B.
What is geometry?One of the first areas of mathematics is geometry, along with arithmetic. It is concerned with spatial characteristics like the separation, shape, size, and relative placement of objects.
Given that In the figure below, angles PQS and TQR are congruent. Angle SQT is 15° larger than angle PQS.
The measure of the angle SQT is,
2∠PQS + ∠SQT = 180
2∠PQS + ∠PQS + 15 = 180
3∠PQS = 165
∠PQS = 55°
The measure of the angle ∠SQT is,
∠SQT = 55 + 15
∠SQT = 70

The number of children x, belonging to each of eight families registering for swimming was 3,2,6,3,4,2,5,6. Find the mean, x. (Give answer correct to 2 decimal places.)
The mean number of children per family is 3.88.To find the mean (average) of the number of children in the eight families, we sum up the number of children and divide by the total number of families.
Given the number of children in each family:
3, 2, 6, 3, 4, 2, 5, 6
Step 1: Sum up the number of children:
3 + 2 + 6 + 3 + 4 + 2 + 5 + 6 = 31
Step 2: Divide by the total number of families (which is 8 in this case):
31 / 8 = 3.875
Rounding the mean to two decimal places, we have:
Mean = 3.88
Therefore, the mean number of children per family is 3.88.

In AJKL, the measure of ZL=90°, JK = 7.3 feet, and KL = 4.7 feet. Find the measure
of ZJ to the nearest tenth of a degree.
Answer:
40.1°
Step-by-step explanation:
JK is the hypotenuse of the right triangle.
For angle J, KL is the opposite leg.
sin A = opp/hyp
sin J = 4.7/7.3
J = sin^-1 4.7/7.3
J = 40.1

Joanna is selling tickets for the school play $he ha$ already $old $35
worth of tickets. $he ha$ seven ticket$ left to sell for $5 per ticket. write
function to describe the total amount of money collected if she sells every single ticket
Answer:
okay, so given we have that she has already sold $35 worth of tickets. We know that she has seven tickets left to sell, and each is worth $5. So, we would do 7×$5=$35
Next, we would add $35(from the previous money she has made) and $35 (the money she just made from the 7 tickets) and that would equal $70
equation: y=35+7(5)

Step-by-step explanation:
Video Store A charges $8 to rent a video game for one week. Although only members can rent from the store, membership is free. Video Store B charges only $4 to rent a video game for one week. Only members can rent from the store and membership is $84 per year. After how many video game rentals will the total amount spent at each store be the same?
a) Write an equation to model the problem. Let x represent the number of video game rentals.
b) Solve the equation to find to answer the question. (Note: Include the units , which in this case is "rentals"; for example, if you find of a solution of 29, write: 29 rentals.)
Answer:
21 rentals
Step-by-step explanation:
Video Store A = 8x
Video Store B = 84 + 4x
x = number of video game rentals.
After how many video game rentals will the total amount spent at each store be the same?
Video Store A = Video Store B
8x = 84 + 4x
8x - 4x = 84
4x = 84
x = 84/4
x = 21 rentals

_inches
Answer:
h = 8 inches
Step-by-step explanation:
Since these shapes are similar and one side of the bigger shape is double the other side (44 is the double of 22), to find side h, you have to multiply 4 by 2 (It's the same relationship between the two sides of similar shapes). 4 times 2 is equal to 8, which is your answer.
