what are the angle measures of a and s?
Answer:
Q=91, S = 153
Step-by-step explanation:
QR and TS are parallel (see the arrows in the middle?). Means that angles T and Q add up to 180 - they are conjugate angles. Thus Q has to be 89 (since 89+91=180).
Same difference for R and S: they add up to 180 and since one is 27, the other has to be 153.

Jerry climbed 250 steps in 12 1/2 minutes. How many steps did he average per minute?
Work Shown:
12 & 1/2 = 12 + 1/2 = 12 + 0.5 = 12.5
Jerry climbed 250 steps in 12.5 minutes
unit rate = (250 steps)/(12.5 min)
unit rate = (250/12.5) steps per min
unit rate = 20 steps per min
The unit rate is basically the same as the average speed.

A piece of wood that is 3/4 meter long is being cut into smaller pieces that are each 1/10 meter long. Which equation could be solved to find the number of pieces, n, that can be made?
Answer:
7 1/10 meter long pieces ca be made.
Step-by-step explanation:
First, find the common denominator between 3/4 and 1/10. If you multiply 1/10 by 2/2 you get 2/20. If you multiply 3/4 by 5/5 you get 15/20. Now that we have the common denominator, how many times can 2/20 go into 15/20? Since 2 x 7 = 14, the answer is 7.

Using the t-distribution, as we have the standard deviation for the sample, the 95% confidence interval is (71.63, 84.36).
What is a t-distribution confidence interval?The confidence interval is:
[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]
In which:
[tex]\overline{x}[/tex] is the sample mean.t is the critical value.n is the sample size.s is the standard deviation for the sample.The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 4 - 1 = 3 df, is t = 3.1824.
The parameters are given as follows:
[tex]\overline{x} = 78, s = 10, n = 4[/tex]
Hence, the bounds of the interval are given by:
[tex]\overline{x} - t\frac{s}{\sqrt{n}} = 78 - 3.1824\frac{10}{\sqrt{4}} = 71.63[/tex]
[tex]\overline{x} + t\frac{s}{\sqrt{n}} = 78 + 3.1824\frac{10}{\sqrt{4}} = 84.36[/tex]

A fully inflated basketball has a radius of 12
centimeters. How many cubic centimeters of air does
your ball need to fully inflate?
Express your answer in terms of pi.
Then estimate your answer using 3.14 to approximate pi
The volume of air needed is equal to the volume of the sphere, which is 7,234.56 cm^3.
How to get the volume of a sphere?The volume of air that we need is equal to the volume of the basketball.
Remember that for a sphere of radius R, the volume is:
V = (4/3)*3.14*R^3
In this case, the radius is 12cm, replacing that we get:
V = (4/3)*3.14*(12cm)^3 = 7,234.56 cm^3
Then, to fully inflate the ball, we need 7,234.56 cm^3 of air.

A cylindrical can has an 8-cm radius and a height of 11 cm. Find its surface area.
Answer:
955.168 cm²
Step-by-step explanation:
The formula to find the surface area of a cylinder is :
Surface area = 2 π r ( r + h )
Here,
r ⇒ radius ⇒ 8 cm
h ⇒ height ⇒ 11 cm
So, Let us solve now.
Surface area = 2 π r ( r + h )
Surface area = 2 × 3.142 × 8 ( 8 + 11 )
Surface area = 50.272 × 19
Surface area = 955.168 cm²
Which equation results from taking the square root of both sides of (x 9)2 = 25?
The values of the x when the square root is taken on both sides are negative 4 and negative 14.
What is Algebra?Algebra is the study of mathematical symbols and the rule involves manipulating these mathematical symbols.
The equation is given below.
(x + 9)² = 25
Taking square root on both sides, then we have
(x + 9) = ±5
When the positive sign is considered, then we have
x + 9 = 5
x = -4
When the negative sign is considered, then we have
