The ratio of cars to trucks is 9:4. The ratio of trucks to SUV's is 12:21. There are 54 cars.

Elenna [48]

Answer:

Number of trucks = 24

Number of SUVs = 24

Step-by-step explanation:

The ratio of cars to trucks is 9:4

The total ratio of cars to trucks is

9+4 = 13

Let x = sum of cars and trucks.

There are 54 cars. Therefore,

x = 54 + t trucks

Number of cars = ratio of cars/ total ratio × sum of cars and trucks. This means,

54 = 9/13 × x

9x / 13 = 54

9x = 13 × 54

9x = 702

x = 702 / 9 = 78

x = 54 + t trucks = number of trucks = 78 = 54 + t trucks

t trucks = 78 - 54 = 24

Number of trucks = 24

The ratio of trucks to SUVs is 12:21

The total ratio of cars to trucks is

12 + 21 = 33

Let y = sum of trucks and SUVs

There are 24 trucks. Therefore,

x = 24 + s SUVs

Number of trucks = ratio of trucks / total ratio × sum of trucks and SUVs. This means,

24 = 12 / 33 × y

12y / 33 = 24

12y = 24 × 33

12y = 792

y = 792 / 12 = 66

y = 24 + s SUVs

66 = 24 + s SUVs

s SUVs = 66 - 24 = 42

Number of SUVs = 24

Question 7 of 25 Which of the binomials below is a factor of this trinomial? x - 6x-16 O A. X-1 O B. X-8 OC. X-16 O D. x-2

kvasek [131]

Answer:

(x-8) is the factor.

Step-by-step explanation:

The given trinomial is $x^{2}-6x-16$ .

We need to find the factor of this trinomial.

$x^{2}-6x-16=x^2-8x+2x-16\\\\=x(x-8)+2(x-8)\\\\=(x+2)(x-8)$

The factors of $x^{2}-6x-16$ is (x-2) and (x-8).

So, the factor of $x^{2}-6x-16$ is (x-8). Hence, the correct option is (B).

The Table Shows a proportional relationship between x and y for each Value of x and y match it to the correct unit rate y/x in i

Elden [556K]

The correct proportions are given as follows:

x = 3, y = 27: 9/1.

x = 9, y = 81: 9/1.

x = 21, y = 126: 6/1.

x = 14, y = 84: 6/1.

x = 12, y = 36: 3/1.

x = 15, y = 45: 3/1.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The proportions for this problem are given dividing y by x, hence:

x = 3, y = 27: 27/3 = 9, hence 9/1 has to be marked.

x = 9, y = 81: 81/9 = 9, hence 9/1 has to be marked.

x = 21, y = 126: 126/6 = 6, hence 6/1 has to be marked.

x = 14, y = 84: 84/14 = 6, hence 6/1 has to be marked.

x = 12, y = 36: 36/12 = 3, hence 3/1 has to be marked.

x = 15, y = 45: 45/15 = 3, hence 3/1 has to be marked.
