Answer:

there are 10 of the other kind of cars

Step-by-step explanation:

Answer:

10%

Step-by-step explanation:

since there are 100 cars it makes it easy to make into a percentage. so since there are only 10 cars the awnser is 10%

Answer:

1.   y = -10x - 5

2.  [tex]y = \frac{9}{5}x - 4[/tex]

3.  [tex]y = -\frac{5}{4}x + 5[/tex]

4. y = 7x + 5

Step-by-step explanation:

use y = mx + b

m = slope

b = y-intercept

1. Slope= -10, y- intercept = -5

   y = -10x - 5

2. Slope= - 9/5, y- intercept = -4

   [tex]y = \frac{9}{5}x - 4[/tex]

3. Slope= -5/4, y- intercept = 5

    [tex]y = -\frac{5}{4}x + 5[/tex]

4. Slope= 7, y- intercept = 5

    y = 7x + 5

Answer:

t - (t x24%)

Step-by-step explanation:

Value of truck at the time of purchase was t dollars

value decreased by 24%

current value = t x 24%

t - (t x 24%).

current value = t -(t x 24%).

Answer:

x = -55

Step-by-step explanation:

7 + x/5 = -4

Combine the constants.

x/5 = -11

Multiply both sides by 5 to simplify the denominator.

x = -55

Check.

7 + (-55)/5 = -4

7 + (-11) = -4

7 - 11 = -4

-4 = -4

Your answer is correct.

Hope this helps!

Answer:

[tex]7 + \frac{x}{5} = - 4 \\ \frac{x}{5} = - 4 - 7 \\ = - 11 \\ x = - 11 \times 5 \\ = - 55[/tex]

I believe it is: 6n+8+7y+4m

Step-by-step explanation:

You can't do anything about the numbers with variables afterwards, so you just list those and you just add and subtract the numbers without variables.  Since the top and bottom are the same, you just list it once.  Sorry, not the best explanation.  Please let me know if I am wrong.  It's been a while since I had to any type of algebra.

Answer:

A

Step-by-step explanation:

We are given:

[tex]\displaystyle \cos(\theta)=-\frac{12}{13},\,\theta\in\text{QIII}[/tex]

Since cosine is the ratio of the adjacent side over the hypotenuse, this means that the opposite side is (we can ignore negatives for now):

[tex]o=\sqrt{13^2-12^2}=\sqrt{25}=5[/tex]

So, the opposite side is 5, the adjacent side is 12, and the hypotenuse is 13.

And since θ is in QIII, sine/cosecant is negative, cosine/secant is negative, and tangent/cotangent is positive.

Cosecant is given by the hypotenuse over the opposite side. Thus:

[tex]\displaystyle \csc(\theta)=\frac{13}{5}[/tex]

Since θ is in QIII, cosecant must be negative:

[tex]\displaystyle \csc(\theta)=-\frac{13}{5}[/tex]

Our answer is A.

Answer:

90 peanut butter

Step-by-step explanation:

Total number of cookies [tex]=240[/tex]

Number of chocolate cookies [tex]=\frac{1}{4}(240)=60[/tex]

Therefore,

Number of remaining cookies [tex]=240-60=180[/tex]

Number of raisins [tex]=\frac{1}{2}(180)=90[/tex]

So,

Number of peanut butter [tex]=180-90=90[/tex]

Answer:

Answer:

The rectangular pan will hold more batter

Step-by-step explanation:

To find the volume of a rectangular prism, such as the first cake pan, you need to multiply all of the dimensions. The equation looks like this: "V = l * w * h" substituting the variables with the numbers would make it say "13 * 9 * 2" which would be 234 [tex]in^{3}[/tex]

To find the volume of a cylinder, the equation is "V=π[tex]r^{2}[/tex]h". The radius is half the diameter, so "r" would be 4, being half of 8. The substituted equation would read "π[tex]4^{2}[/tex]2", making the cylinder's volume roughly 100.53 [tex]in^{3}[/tex]

When you take those two numbers, you are able to see that 234 is bigger than 100.53, therefore making the rectangular pan larger.

Answer:

[tex]\frac{22}{30} = \frac{11}{15}[/tex]

and

[tex]\frac{176}{7} = 25 \frac{1}{7}[/tex]

Step-by-step explanation:

First make all the fractions into improper fractions

[tex]1\frac{5}{6} = \frac{11}{6} \\\\2\frac{1}{2} = \frac{5}{2} \\\\3\frac{1}{7} = \frac{22}{7}[/tex]

After doing that put them back into the problems

Problem 1)

[tex]1\frac{5}{6}[/tex]  ÷ [tex]2\frac{1}{2}[/tex] , plug in the improper fractions

[tex]\frac{11}{6}[/tex] ÷ [tex]\frac{5}{2}[/tex]

to divide, you need to flip the second fraction and multiply

[tex]\frac{11}{6}[/tex]· [tex]\frac{2}{5}[/tex] = [tex]\frac{22}{30}[/tex]

then reduce

[tex]\frac{22}{30} = \frac{11}{15}[/tex]

Problem 2)

[tex]3\frac{1}{7}[/tex]÷ [tex]\frac{1}{8}\\[/tex]

Plug in improper fraction

[tex]\frac{22}{7}[/tex] ÷ [tex]\frac{1}{8}\\[/tex]

Then flip second fraction and multiply

[tex]\frac{22}{7}[/tex] · [tex]\frac{8}{1}[/tex]

Multiply

[tex]\frac{176}{7}[/tex]

Reduce, or make it a mixed number

[tex]\frac{176}{7} = 25 \frac{1}{7}[/tex]

Answer:

y=16x+9

y-9=16x

y=16x+9

*Complete Question:

A and B are two similar cylindrical containers.

Surface area of container A: surface area of container B = 4:25

Warda fills container A with oil.

She then pours all the oil into container B.

Warda repeats this and stops when container B is full of oil.

Work out the number of times that Warda fills container A with oil.

Answer/Step-by-step explanation:

We are given that the ratio of surface area of cylinder A to cylinder B = 4:25

To find out the number of times Warda fills cylinder A with oil, we need to find the ratio of the volume of cylinder A to cylinder B.

✔️First, find the linear measurement using the ratio of their surface area by taking their square root:

4:25 = √4/√25 = 2/5

Linear measurement of A to B = 2:5

The ratio of their volume = the cube of the ratio of their linear measurement

Thus, the ratio of the volume of A to B = 2³:5³ = 8:125

For Cylinder B to be filled, it would require 125/8 = 15.625 of cylinder A filled with oil. That means Warda would have to fill Cylinder A with oil for approximately 15 times, then an extra fraction of cylinder A to completely fill cylinder B with oil.

Answer:

Area of the running track = 6900 m²

Step-by-step explanation:

Length of a football pitch = 120 m

Width of the football pitch = 80 m

Area of the football pitch (Inner rectangle) = Length × Width

                                                                      = 120 × 80

                                                                      = 9600 m²

If a running track (width = 15 m) is built around the football pitch,

Length of the outer rectangle = 120 + 2×(15)

                                                  = 120 + 30

                                                  = 150 m

Width of the outer rectangle = 80 + 2×(15)

                                                = 110 m

Area of the outer rectangle = 150 × 110

                                              = 16500 m²

Therefore, area of the track around the football pitch = Outer rectangle - Inner rectangle

= 16500 - 9600

= 6900 m²

Area of the running track = 6900 m²

Answer:

x=4, y=0. (4, 0).

Step-by-step explanation:

3x-4y=12

x=-2y+4

-----------

3(-2y+4)-4y=12

-6y+12-4y=12

-10y=12-12

-10y=0

y=0/-10=0

x=-2(0)+4=0+4=4

Answer:

Step-by-step explanation:

if x=-2y+4

3x-4y=12 becomes

3(-2y+4)-4y=12

-6y+12-4y=12

-10y+12=12

-10y=0

y=0

since x=-2y+4

x=-2(0)+4

x=4

so the solution is the point (4,0)
