marin [14]3 years ago
6 0

Answer:

1. 11

2. -82

3. \frac{8}{15}

4. 36

5. 1

Step-by-step explanation:

1. 3x + 5, when x = 2

Plug in the value of x

3(2) + 5 = 6 + 5

= 11

2. 5xy + x - 4, when x = -3 and y = 5

Plug in the values

5(-3)(5) + (-3) - 4

-75 - 3 - 4 = -82

3. \frac{6ab - c}{abc}, when a = 5, b = 3, and c = 10

Plug in the values

\frac{6(5)(3) - 10}{5*3*10}

\frac{90 - 10}{150}

\frac{80}{150}

\frac{8}{15}

4. 3(xy + 6), when x = -6 and y = - 1

3(-6*-1 + 6)

3(6 + 6)

3(12)

36

5. \frac{2x + 5}{3x - y}, when x = -3 and y = -8

\frac{2(-3) + 5}{3(-3) - (-8)}

\frac{-6 + 5}{-9 + 8}

\frac{-1}{-1} = 1

The volume of the barrel is 4.6 m. It is half water. How many liters of water are there?​
Mariulka [41]

Answer:

2300 liters of water.

Step-by-step explanation:

The volume of the barrel is 4.6 m^3, and we know that this is half--filled with water.

Then the total volume of water inside the barrel is:

(4.6 m^3)/2 = 2.3 m^3

So we have 2.3 m^3 of water, and we want to write this in liters.

We know that 1 liter = 0.001 m^3

then:

1 = (1 L)/(0.001 m^3)

Now we can rewrite:

2.3 m^3 = (2.3 m^3)*1 = (2.3 m^3)* (1 L)/(0.001 m^3) = (2.3 m^3/0.001 m^3)* 1L

2.3 m^3 = 2300 L

So we have 2300 liters of water in the barrel.

A painter leans a 20 foot ladder against a house so that it touches the house 11 feet from the ground. How far from the base of
gogolik [260]

This problem involves using the Pythagorean Theorem which is a^2+b^2=c^2

We already have the values of a and c, but b is unknown. So we plug in: 11^2+b^2=20^2

121+b^2=400

b^2=279

b=sqrt(279)

b=16.7

So the answer is about 16.7 ft

Hope this helped!
