Dvinal [7]

SOLUTION:

Step 1:

In this question, we are given the following:

What is the midpoint of a line segment with the endpoints (-4,-3) and (7,-5)?

A. (-3.5, 1)

B. (1.5,-4)

C. (-4,1.5)

D. (1.-3.5)

Step 2:

The midpoint of a line segment with the endpoints (-4,-3) and (7,-5) is:

$\begin{gathered} (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}) \\ =\text{ (}\frac{-4+7}{2},\frac{-3+(-5)}{2}) \\ =\text{ (}\frac{3}{2},\frac{-8}{2}) \\ \end{gathered}$

$=\text{ (1. 5 , -4 ) --- OPTION B}$

Sharri Pack away how old summer clothes in storage tote that had a length of 3 feet, a width of 4 feet, and a height of 3 feet.

skad [1K]

To find this, you would use the volume formula which is: Volume = Length x Width x Height. In other words, you would be doing 3 x 4 x 3.

Sanjay needs 90 meters of fence to go around a rectangular garden.

Mademuasel [1]

To find the perimeter of a rectangle you can multiply the length by 2 and the width by 2, or you can add the four sides together.

The wrong equation is w + 3w = 90 because it only has one width and one length, which would be half the total perimeter.

Someone please help me w this standard form question

svp [43]

Answer:

2.4 × 10⁶

Step-by-step explanation:

Given:

$\sf x=3.8 \times 10^5$

$\sf y=5.9 \times 10^4$

To calculate the value of R, substitute the given values into the given formula:

$\begin{aligned}\sf R & = \sf \dfrac{x^2}{y}\\\\ \implies \sf R& = \sf \dfrac{(3.8 \times 10^5)^2}{5.9 \times 10^4}\\\\& = \sf \dfrac{3.8^2 \times (10^5)^2}{5.9 \times 10^4}\\\\& = \sf \dfrac{14.44 \times 10^{10}}{5.9 \times 10^4}\\\\& = \sf \dfrac{14.44}{5.9} \times \dfrac{10^{10}}{10^4}\\\\& = \sf 2.4474... \times 10^{(10-4)}\\\\& = \sf 2.4474... \times 10^6\\\\\end{aligned}$

Therefore, the value of R to 1 decimal place is 2.4 × 10⁶
