Right angle because that has 90 degree angle

VikaD [51]3 years ago

5 0

Let say one angle is X and other angle is 44x because it is x times 44 so

         X+44X=90

         45X=90

       X=2 so one of them is 2 and the other one is 2 times 44 which is 88

Sophia walked 6 miles in 90 min at Bear Creek Park in Euless, Texas. If she continues at this rate how many miles could walk in

otez555 [7]

Answer:

First you should determine in how many minutes she walks just one mile. For this, you just divide 90:6 and you get 1 mile in 15 minutes. After this, you just divide 60:15 and so you get 4 miles.

Easy Sample Ap graphing 50pts! (Easy points!!) (ASAP) (URGENT) (Please check my other questions) Please

Answer:

a) See attachment 1.

b) t² and D

c) See attachment 2.

d) g = 9.8 m/s² (1 d.p.)

Step-by-step explanation:

See attachment 1. The line of best fit is shown in red.

The quantities the student should graph in order to produce a <u>linear relationship</u> between the two quantities are t² and D.

Make a table of values of t² and D:

$\begin{array}{|l|l|l|l|l|l|}\cline{1-6} \rm t^2& 0.0196& 0.1024& 0.2116 & 0.3481& 0.3969\\\cline{1-6} \rm D & 0.10 & 0.50& 1.00 & 1.70 & 2.00\\\cline{1-6}\end{array}$

<u>Plot</u> a graph of D against t² and draw a line of best fit (see attachment 2).

From inspection of the graph, the line of best fit passes through the origin (0, 0) and (0.1024, 5.0). Therefore, use these two points to find the slope of the line:

$\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{0.5-0}{0.1024-0}=4.8828125...\:\rm m/s^2$

Therefore:

$\rm \implies \dfrac{1}{2}g=4.8828125...\:\rm m/s^2$

$\rm \implies g=2 \cdot 4.8828125...\:\rm m/s^2$

$\rm \implies g=9.8\:\rm m/s^2\:(1\:d.p.)$

PLEASE HELP<br> What is the measure of ∠I? Explain.<br> Describe the relationship between ∠H and ∠L.

Llana [10]

The Relationship between Angle H and Angle L is that they are Corresponding Angles. Corresponding Angles are angles that equal to each other and are on the same side of the tranversal.

Sorry I don't know the answer to the first one without numbers. Hope that helped!

What is the area of a regular heptagon that has 4 inch sides and an apothem of 4.2 inches?

Lelu [443]

A = (1/2) * apothem * pperimeter
A = (1/2) * 4.2 * (4 * 7)
A = 58.8 inches
