Answer 1
Answer:

The length of PR is 4.4 units.

Explanation:

It is given that the length of the hypotenuse is 10 units.

Also, the angle of R is 64°

To find the length of PR, we shall use the cosine formula,

\cos \theta=(a d j)/(h y p)

Here,  \theta=64, adj = PR and hyp = 10

Substituting these values in the formula, we get,

\cos 64=(P R)/(10)

Multiplying both sides by 10, we get,

10*\cos 64={P R}

Substituting the value for cos 64, we get,

10*0.438={P R}

Multiplying, we have,

4.38=PR

Rounding off, we get,

PR=4.4

Thus, the length of PR is 4.4 units.

Why is important to maintain an assessment’s validity, reliability, and equity in testing?

Two lines, C and D, are represented by the equations given below:Line C: y = x + 12
Line D: y = 3x + 2

Which of the following shows the solution to the system of equations and explains why? (5 points)


(4, 14), because one of the lines passes through this point
(4, 14), because the point lies between the two axes
(5, 17), because both lines pass through this point
(5, 17), because the point does not lie on any axis

Answers

Line C: y = x + 12
Line D: y = 3x + 2

(4,14)
C: y = 4 + 12 = 16
D: y = 3(4) + 2 = 12 + 2 = 14

(5,17)
C: y = 5 + 12 = 17
D: y = 3(5) + 2 = 15 + 2 = 17

(5,17) shows the solution to the system of equations, because both lines pass through this point.

Linda walked 3/4 of the length of the Tremont Trail before stopping for a rest. How far had Linda walked on the trail? Tremont Trail:3 1/2 miles Seton Trail:1 1/4 miles Wildflower Trail:2 3/8 miles 15 POINTS WILL MARK BRAINLIEST PLZ HURRY

Answers

Answer:

2 5/8 miles or 2.625 miles

Step-by-step explanation:

We are told in the question that

Linda walked 3/4 of the length of the Tremont Trail before stopping for a rest.

From the question, the length of the Tremont Trail = 3 1/2 miles

Hence, the distance (how far )Linda has walked =

3/4 of 3 1/2 miles

= 3/4 × 3 1/2 miles

= 3/4 × 7/2 miles

= 21/8 miles

= 2 5/8 miles or 2.625 miles

Therefore, Linda had walked 2 5/8 miles or 2.625 miles on the Tremont trail

Of the following, which statement or statements accurately represent possible effects of a long-term credit purchase on your credit score?l. Showing a willingness to pay high interest rates increases your score

Ill. Regularly paying off a credit balance can boost your score.

a. I and Ill

b. ll only

c. ll and I

d. l, ll, and III

Answers

C is the correct answer. Statements II and III are true. Making minimum payments suggests you are not earning enough money to pay off the bulk of your debt, only that you are managing to stay afloat. Regularly paying off your credit balance, however, demonstrates that you are financially able to support yourself.
