Ratio of perimeters of smaller solid to larger solid = ratio of the sides of the corresponding sides of smaller solid and larger solid .

Let the perimeter of smaller solid =x and perimeter of larger solid =y. Therefore

\frac{x}{y} = \frac{52}{68}

\frac{x}{y} = \frac{13}{17}

Therefore the answer is 13/17 .

When Lorenzo finished his exam last week, he thought the test was over. But the instructor put z-scores on each student's paper
Anarel [89]

Answer:

Lorenzo's score on exam was 75.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 61

Standard Deviation, σ = 8

We are given that the distribution of test score is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

z-score = 1.75

We have to find the value of x.

Putting values, we get

1.75 = \dfrac{x - 61}{8}\\\\x = 1.75(8) + 61\\x = 75

Thus, Lorenzo's score on exam was 75.

I WILL MARK BRAINLEST!!! FOR YOU CAN ANSWER THESE TWO
ludmilkaskok [199]

Answer:

First question: 1.4

Second question: Option 3

Step-by-step explanation:

First question:

You simplify the left equation first,

-0.4 x -3.5 = 1.4 , -0.4 x 2.9 = -1.16

<u>1.4k - 1.16</u>

For this to equal the right equation, the number missing must be 1.4.

Second question:

You simplify the equation given to you first,

1/4 x 8 = 2 , 1/4 x 12 = 3

<u>2x + 3</u>

The option that is equivalent to the answer is option 3; 2x + 3
