A photocopy was made of julie's watercolor painting. the photocopy resized the painting so that it measured 4 inches wide by 7 inches long. if the actual painting is 16 inches wide, what is the length A.28 inches
B.9.14 inches
C.38 inches
D.64 inches

Answers

First, set up a ratio.

4:7= 16:x
You mutiply 4 by 4 to get 16, so you multiply 4 to 7.

4:7= 16:28
Therefore, the answer is A, 28 inches.

The temperature on Wednesday was 8° more than a third of Tuesday’s temperature. If T represents Tuesday’s temperature, write an expression for Wednesday’s temperature, W.

Answers

I love these problems -- you don't have to do math -- it's all just reading and using logic! So we're saying T represents Tuesday. 8 more than can be expressed as what?  +8. A third can be expressed as what? 1/3. What are we splitting into thirds? T. Therefore, 1/3t+8 is your answer.

Which statement is true for the equation 2x - 2x - 7 = -7?a. It has infinitely many solutions
b. It has two solutions
c. It has one solution
d. it has no solution

Answers

Answer: Option 'a' is correct.

Step-by-step explanation:

Since we have given that

2x-2x-7=-7

We need to solve it first as follows:

2x-2x-7=-7\n\n2x-2x=-7+7\n\n0=0

Since L.H.S. = R.H.S.

So, it satisfies the equation for all x.

So, there will be infinitely many solutions.

Hence, Option 'a' is correct.
2x-2x-7=-7 \n (2-2)x-7=-7 \n 0x-7=-7 \n-7=-7 \n true

The equation is satisfied for every x, so it has infinitely many solutions.
The answer is A.

Express the number in polar form 4 - 4i

Answers

Polar form of a complex number is r( cos(theta) + i sin(theta) )
r is equal to the total distance created by the rectangular coordinates of the complex number
r = Root(4^2 + (-4)^2) = Root(32) = 4 Root(2)
To find theta, if a > 0, use arctan(b/a), where:
a = the first number
b = the second number
arctan (-4/4) = -45 degrees (-0.7854 radians)
Your answer is 4 Root(2) (cos(-45) + i sin(-45))
