If AC = 2x + 13 and DB = 4x - 1. Find DB

Answer:

Step-by-step explanation:

Givens:

Eq. 1 )  x + y = 5

Eq 2 )  x = 1 + y  

plug x into Eq 1 from Eq 2

(1+y) + y = 5

algebra them out

2y = 4

y = 2

then

x + 2 = 5

x = 3

Answer:

0.07x - 0.002x^2 - 0.3

Step-by-step explanation:

Given the expression shown (0.2x-1)+(0.3-0.01x)

Expand

(0.2x-1)+(0.3-0.01x)

= 0.2x(0.3)  - 0.2x(0.01x)-1(0.3) + 1(0.01x)

= 0.06x - 0.002x^2 - 0.3 + 0.01x

= 0.06x+0.01x - 0.002x^2 - 0.3

= 0.07x - 0.002x^2 - 0.3

This gives the required expression

Answer:

c

Step-by-step explanation:

Answer:

c. 492 cubic centimetres

Step-by-step explanation:

the equation for the volume of a rectangular prism is

V = Length × Width × Height

we also have to take into account that there are 2 rectangular prisms in that picture so we have to add the volumes of both of them.

for the one on the bottom, the volume would be

V = 9 × 6 × 8

V = 432 cubic centimetres

now we'll do the one on the top

V = 3 × 5 × 4

V = 60 cubic centimetres

now we'll add up both volumes to get a total amount.

432 + 60 = 492 cubic centimetres

Given:

The bases of trapezoid measuring 4 m and 12 m.

To find:

The median of the trapezoid.

Solution:

The median of the trapezoid is the average of its bases.

[tex]\text{Median}=\dfrac{\text{Upper base + Lower base}}{2}[/tex]

The bases of trapezoid measuring 4 m and 12 m. So, the median of the trapezoid is:

[tex]\text{Median}=\dfrac{4+12}{2}[/tex]

[tex]\text{Median}=\dfrac{16}{2}[/tex]

[tex]\text{Median}=8[/tex]

Therefore, the correct option is C.

Answer: See explanation

Step-by-step explanation:

Your question isn't complete but I believe that you want to know the number of rides that Katie can take.

Based on the information in the question, we can form an equation. Let the number of rides that Katie can take be represented by x. Therefore,

12 + (1.25 × x) = 50

12 + 1.25x = 50

1.25x = 50 - 12

1.25x = 38

x = 38/1.25

x = 30.4

Therefore, Katie can take at most 30 rides.

Answer:

It is x2 -4  because it correct

Answer:

center: (-4, -1)

radius: 7

Step-by-step explanation:

The standard equation of a circle is represented by the formula:

(x - h)^2 + (y - k)^2 = r^2

where (h, k) is the center and r is the radius. From the equation we have, we can say that

h = -4

k = -1

r = √49 = 7

So, the center is (-4, -1) and the radius is 7.

Here is a vague graph of what this equation may look like:

Answer:

[tex](x+4)^2+(y+1)^2=49[/tex]

[tex]standard ~equation ~of ~circle:[/tex]

[tex](x-h)^2+(y-k)^2=r^2[/tex]

[tex]Center (h,k)=(-4,-1)[/tex]

[tex]radius, r=7[/tex]

There are 60 minutes in 1 hour, so ir you multyply 21 x 6 your answer will be 126.

Answer:

126

Step-by-step explanation:

there are 60 minutes in an hour so divide 60 by 10 to get 6 and multiply by 21 to get 126

Answer:

A. The y-intercept represents the amount of money Stephanie has. She started at -16 because she spent $16.

B. The x-intercept is the amount of cups of lemonade she sold. On the graph, it shows that after 8 cups, she made 16 dollars back. She didn't make any profit sense she started at -16.

C. The slope represents how much she made after so many cups of lemonade were sold. It was after 8 cups of lemonade were sold that she started making a profit.

Answer:

Step-by-step explanation:

b/c it's the complement of 47 we know it's 180-47 = x

or

x = 133°

Answer:

x = 133 degrees

Step-by-step explanation:

The 47 degrees is a corresponding angle with the angle on the right of x. Meaning that angle is also 47 degrees. After figuring that out, all you have to do is do subtraction (180-47=133) to get your answer.

Answer:

1) A week: $151.74

2) A month : $606.96

3) A years : $7890.48

Step-by-step explanation:

Custodian at Movie Theater

pay:$9.95

per hours:

15.25 hours per week

How much do they make in

1) a- week

1 week = 15.25 hours

Hence,

1 hour = $9.95

15.25 hours = x

Cross Multiply

x = 15.25 × $9.95

x = $151.7375

Approximately = $151.74

2) A month

There are 4 weeks in a month

1 week = $151.74

4 weeks = x

Cross Multiply

x = 4 × $151.74

x = $606.96

3) A year

There are 52 weeks in a year

Hence,

1 week = $151.74

52 weeks = x

Cross Multiply

x = 52 × $151.74

x = $7890.48

Therefore, they made in :

1) A week: $151.74

2) A month : $606.96

3) A years : $7890.48

Answer:

  (-5, -2)

Step-by-step explanation:

That point P can be found from ...

  P = A + 1/5(B -A)

  P = (4/5)A +(1/5)B = (4A +B)/5

  P = (4(-6, -4) +(-1, 6))/5 = (-24-1, -16+6)/5 = (-25, -10)/5

  P = (-5, -2)

Answer:

30

Step-by-step explanation:

2x+(x-6). We know that x=12 so we replace x with 12. This means the expression will be 2(12)+(12-6). Now, we just have to simplify. 24+6. 24+6=30 so the answer is 30.
