A kenne is moving 160 dogs to a new facility. Each dog has its own crate. The facility manager rents 17 trucks. Each truck holds
Margarita [4]
160 9 = 17 r7
A remainder of 7 means that 7 dogs and their crates do not fit in the 17 trucks. 

Having a remainder lets me know that not all of the dogs and their crates will fit in the 17 trucks. The facility manager did not rent enough trucks.

What is the result of a dilation of scale factor 3 centered at the origin of the line 2y + 3x=10
romanna [79]

Answer:

(10, 15)

Step-by-step explanation:

To get the origin of the equation 2y+3x = 10, we need to get the x and y-intercept of the line.

x-intercept occurs at y = 0

If y = 0

2(0)+3x =10

3x =10

x = 10/3

x = 1.33

y-intercept occurs at x = 0

If x = 0

2y+3(0) =10

2y =10

y = 10/2

y = 5

Hence the coordinate at the origin is (10/3, 5). If this coordinate is dilated by 3, the required coordinate will be at (10/3*3, 5*3) = (10, 15)

Hence the required coordinate is (10, 15)

Given f(x)=3x^2+5 and g(x)=x−2 . What is (fg)(x) ? 3x^2−x+7 3x^3−6x2+5x−10 −3x^2+x−7 3x^3−10
wolverine [178]

For this case we have that by definition:

(fg) (x) = f (x) * g (x)

So:

(fg) (x) = (3x ^ 2 + 5) (x-2)

We apply distributive property that states that:

(a + b) (c + d) = ac + ad + bc + bd

In addition, we take into account that:

+ * - = -

(fg) (x) = 3x ^ 3-6x ^ 2 + 5x-10

Answer:

3x ^ 3-6x ^ 2 + 5x-10

Option B

Solve the proportion using cross products. Round to the nearest hundredth if necessary. $18.45/m gal = $3.60/7.5gal
sveta [45]
\dfrac{\$18.45}{n \text { gallon}}  =  \dfrac{\$3.60}{7.5 \text { gallon}}

Cross multiply
n \times \  3.60 = 7.5 \times \  18.45

Combine like terms
3.60n = 138.375

Find n
n = 138.375\div 360

Answer
n = 0.38 \text { (nearest hundredth)}

-0.4a + 3 = 7 <br> a = <br> plz help
Papessa [141]

Answer:

a = -10

Step-by-step explanation:

-0.4a + 3 = 7

subtract 3 from each side

-0.4a + 3-3 = 7-3

-.4a = 4

Divide each side by -.4

-.4a/ -.4 = 4/-.4

a = - 10
