During the morning commute 60 cars and 12 trucks passed through the intersection. What is the ratio of cars to trucks?​

Answers

Answer: 60:12, 60/12, or 60 to 12.

Step-by-step explanation:

To find the ratio, we must find 2 values. The values in this case is 60 and 12. 60 being cars and 12 being trucks.

So to write the ratio, we must put the cars first, then the trucks second.

So 60 first, and 12 second.

And remember, there are 3 ways to write ratios.

So we can write it like 60:12, 60/12, or 60 to 12.

The answers are 60:12, 60/12, or 60 to 12.

1. f(x)=x^2−4x, find f(−3)

2. f(x)=x^2−x, find f(−10)

3. f(x)=3x+1, find f(−3)

4. f(x)=4x−2, find f(8)

5. f(x)=x^2+2, find f(0)

Answers

f(x) is a function that takes some number x and outputs another one.

To get the output value, replace every instance of x in f(x) with the given number.

1. If f(x) = x ² - 4x, then

f (-3) = (-3)² - 4(-3) = 9 + 12 = 21

2. f(x) = x ² - x, so

f (-10) = (-10)² - (-10) = 100 + 10 = 110

3. f(x) = 3x + 1, so

f (-3) = 3(-3) + 1 = -9 + 1 = -8

4. f(x) = 4x - 2, so

f (8) = 4(8) - 2 = 32 - 2 = 30

5. f(x) = x ² + 2, so

f (0) = 0² + 2 = 0 + 2 = 2

A shoe store buys a shipment of nike shoes that cost $70 each to the purchases. They want to markup their prices for the customers by 30%. How much would the customer pay for a pair of nikes

Answers

Given :

A shoe store buys a shipment of Nike shoes that cost $70 each to the purchases.

They want to markup their prices for the customers by 30%.

To Find :

How much would the customer pay for a pair of Nikes.

Solution :

C.P = $70 .

It is given that selling price is 30% more than the S.P.

So, S.P = C.P + C.P×0.30

S.P = C.P×1.30

S.P = 70×1.30

S.P = $91.

Therefore, the customer would pay $91 for a pair.

Answer:

  B

Step-by-step explanation:

The given equation is in slope-intercept form:

  y = mx + b

where the slope is m = -3 and the y-intercept is b = +2.

So, the graph will have a slope of ...

  "rise"/"run" = -3 = -3/1

and will cross the y-axis at y=2.

Graphs A and B cross the y-axis in the right place, but only Graph B has a negative "rise" a x increases.

Answers

Answer:

  m∠W = m∠S = 126°

  m∠E = m∠T = 54°

  x = 24

  y = 8

Step-by-step explanation:

Opposite angles of a parallelogram are congruent, so we have ...

  ∠E = ∠T

  3x -18 = 2x +6

  x = 24 . . . . . . . . . add 18-2x

Then the measure of these angles (in degrees) is ...

 ∠E = ∠T = 2x+6 = 2(24) +6 = 54

__

The adjacent angle W is supplementary to either of these:

  ∠W = 180° -∠E

  15y +6 = 180 -54

  15y = 120

  y = 8

  ∠W = ∠S = 126°

Answer:

y = 8

Angle S= 126°

9 Jean Junction is selling jeans at 25% off the regular price. Jeans regularly sell for $35. What is the cost of the jeans on sale?​

Answers

Answer:

$26.25

Step-by-step explanation:

we can convert 25% directly to a decimal:

25% = 0.25

Then we find

25% of 35 = 0.25 x 35 = 8.75

35 - 8.75 = 26.25

So the jeans on sale cost $26.25

the sale price of the jeans will be $26.25
