D - 2 < -1

D < -1 + 2 -2 crosses the inequality sign and it changes to +2

D < 2 - 1

D < 1. This is the inequality.

I hope this helps.

What is the volume of the rectangular prism?

Gnesinka [82]

Answer:

Option (4)

Step-by-step explanation:

Volume of a rectangular prism is given by the formula,

Volume = Length × Width × Height

From the picture attached,

Length of the prism = 5 cm

Width of the prism = $3\frac{3}{4}$ = $\frac{15}{4}$ cm

Height of the prism = $8\frac{1}{2}$ = $\frac{17}{2}$ cm

Volume of the given prism = $\frac{5}{1}$ × $\frac{15}{4}$ × $\frac{17}{2}$

= $\frac{5\times 15\times 17}{1\times 4\times 2}$

= $\frac{1275}{8}$

= $159\frac{3}{8}$ cm³

Therefore, Option (4) is the correct option.

How many kilometers are in 765 yards? 1 yard = 3 feet 1 mile = 5,280 feet 1 kilometer = 0.621 miles

luda_lava [24]

Answer:

There are 0.70km in 765 yards.

Step-by-step explanation:

This is a problem of conversion of units, that can be solved by multiple rule of three's.

The first step is converting 765 yards to feet. We have that each yard has 3 feet, so

1 yard- 3 feet

765 yards - x feet

x = 765*3

x = 2295

So, in 765 yards there are 2295 feet.

Now, we have to convert 2295 feet to miles. Each mile has 5280 feet, so:

1 miles - 5280 feet

x miles - 2295 feet

5280x = 2295

x = 0.435 miles

So, in 765 yards there are 2295 feet which is 0.435 miles

Now, the final step is converting from miles to kilometers. Each km has 0.621 miles, so:

1km - 0.621 miles

xkm - 0.435 miles

0.621x = 0.435

x = 0.70km

So, there are 0.70km in 765 yards.

Mariana is taking a multiple choice test with a total of 80 points available. Each question is worth exactly 4 points. What woul

Sladkaya [172]

Mariana's score if got right if she got 5 wrong is 60 points.

Mariana's score if got right if she got xx wrong is 80 - 4xx.

<h3>What is Mariana's score?</h3>

The first step is to determine the number of questions that Mariana got right. In order to get the number of questions that she got right, subtract the total number of number of questions from the questions that he got wrong.

Questions that Mariana got right = total number of questions - questions he got wrong

Total number of questions = total number of points / point of each question

Total number of questions = 80 / 4

Total number of questions = 20

Questions that Mariana got right if he got 5 wrong = 20 - 5 = 15

Mariana's score = questions she got right x number of points per question

Mariana's score = 15 x 4 = 60 points

Questions that Mariana got right if he got x wrong = 20 - xx

Mariana's score = (20 - xx) x 4

Mariana's score = 80 - 4xx
