Answers

Answer 1

Answer:

Answer:

The surface area is: 225 in²

Step-by-step explanation:

Good Day mate!

I'm here to answer your question!

Area of each triangular base:

$(1)/(2)(7.5)(10)=37.5$

Area of the rectangular faces:

$5 * 10=50$

$5 * 12.5=62.5$

$7.5 * 5=37.5$

Add to find the surface area:

$37.5+37.5+50+62.5+37.5=225$

Thus, the surface area is : 225²

The total capacity of 6 pitchers and 12 glasses is 21 liters. The capacity of a pitcher is 5 times that of a glass. Find the capacity of each glass. Give you answer in liters.

Answers

First you must set up an equation. Since there are 6 pitchers and 12 glasses you put. 6p + 12g = 21. Then they give you what p is (5g) and you plug that in and solve for g.

6(5g) + 12g = 21
30g + 12 g = 21
42 g = 21

Divide 42 on both sides to isolate the variable g. You get g = 0.5

The answer is that the capacity of each glass is 0.5 liters.

What is the decimal .387123 rounded to the nearest thousand

Answers

0.387123

Note the place value of each digit

0
.
3 (tenths)
8 (hundredths)
7 (thousandths)
1 (ten thousandths)
2 (hundred thousandths)
3 (millionths)

to find the nearest thousandths, look at the place value of the ten thousandths. It is a 1. Because it is less than 5, you round down.

0.387123 becomes 0.387

0.387 is your answer

hope this helps

It is the nearest thousandth which is the third decimal place. The answer would be .387 unless the 1 was a 5 or higher then it would be .388

Write an equation that is perpendicular to y= 1/2x+5 and passes through (4,8)

Answers

Answer:

y = -2x + 16.

Step-by-step explanation:

The slope of the perpendicular line = -1 / slope of the given line

= -1 / 1/2 = -2.

Using the point slope form of the equation of a straight line:

y - y1 = m (x - x1)

y - 8 = -2(x - 4)

y - 8 = -2x + 8

y = -2x + 16 is the required equation.
