Answer:

if 1/6 of a roll of paper covers 1/4 of a wall, this means that we will need 4/6 of a roll to cover a whole wall, now the question is asking how many rolls will we need to cover 4 walls, we already know that it takes 4/6 to fill one wall so if we add 4/6+4/6+4/6+4/6 we will get 16/6 or 2 4/6

we will need 16/6 or 2 4/6 of rolls of paper to cover 4 walls

Step-by-step explanation:

the first 2 weeks she worked the graph went up, the last 2 weeks she worked less time, so the graphs will go down, but since she worked 15 hours on the third week, and 13 hours on the first week, the third weeks point doesn't go below the first weeks starting point. anyways i hope thats correct

Answer:

10

Step-by-step explanation:

let x = unknown number

three times x is increased by 24

so 3x + 24

this is equal to 16 less than 7 times x

so 3x + 24 = 7x - 16

we now solve for x

3x + 24 = 7x - 16

add 16 to both sides

3x + 24 + 16 = 7x - 16 + 16

3x + 40 = 7x

subtract 3x from both sides

3x - 3x + 40 = 7x - 3x

40 = 4x

divide both sides by 4

40/4 = 10

4x / 4 =x

x=10

the unknown number is 10

Answer:

x = 37

Step-by-step explanation:

2x and 74 are vertically opposite angles and are congruent, so

2x = 74 ( divide both sides by 2 )

x = 37

Step-by-step explanation:

To find the value of x, first, the denominators are made equal by taking the L.C.M. of them.

(3x + 2)/7 + (4(x + 1))/5 = 2/3 * (2x + 1) (45x + 30 + 84x + 84)/105 = (140x + 70)/105

Since both the sides of the equation have the same denominator now, they can be cancelled out.

45x + 30 + 84x + 84 = 140x + 70

The equation can be rearranged by shifting all the x terms on one side of the equation and all the constants on the other side of the equation.

140x - 85x - 45x = 84 + 30 - 70

10x = 44

x = 4.4

Therefore, the value of x is 4.4.

The speed of the parachute is 50ft/s

The formula for calculating speed is expressed as:

Speed  = Distance/Time

Given the following parameters

Distance = 15,000 feet

Time = 30 seconds

Substituting into the formula;

Speed = 1500ft/30s

Speed = 50ft/s

Hence the speed of the parachute is 50ft/s

Answer:

f(g(x)) = 15x3 + 16 dollars over hour

Step-by-step explanation:

I just took the exam and got it right for this problem

Raul works at a movie theatre. The function f(x) represents the amount of money in dollars Raul earns per ticket, where x is the number of tickets he sells. The function g(x) represents the number of tickets Raul sells per hour, where x is the number of hours he works.

f(x) = 3x^2 + 16

g(x) = the square root of five times x cubed

Find f(g(x)).

Answer:

1/6

Step-by-step explanation:

3/4 x 2/9

3*2 = 6

4*9 = 36

6/36 (which can be simplified as 1/6)

Hope this helps!

Step-by-step explanation:

translated (shifted) 2 units to the right (positive x direction) creates the points

(-2 + 2, -2) = (0, -2)

(-2 + 2, -5) = (0, -5)

(-4 + 2, -5) = (-2, -5)

and now we rotate these points 90° clockwise around the origin.

that means a positive x turns into a negative y, a negative y into a negative x, a negative x into a positive y, and a positive y into a positive x.

and a 0 just trades places.

therefore,

(0, -2) becomes (-2, 0)

(0, -5) becomes (-5, 0)

(-2, -5) becomes (-5, 2)

so, overall

(-2, -2) becomes (-2, 0)

(-2, -5) becomes (-5, 0)

(-4, -5) becomes (-5, 2)

Answer:

$21.94

Step-by-step explanation:

I'm not sure how many pizzas were ordered, but let's say you just got one large pizza that was $18.

First, the sales tax - 6%

$18 + 6% = $19.08

Then you give a 15% tip.

$19.08 + 15% = $21.94

Answer:

117°

Step-by-step explanation:

Start by finding the measure of the angle adjacent to the one marked 101 degrees. Since they are a linear pair, they add up to 180 therefore...

101+y=180

Subtract 101 from both sides...

y=79

Now, using the exterior angle theorem (the exterior angle is equivalent to the sum of the two interior angles that are NOT adjacent to the exterior angle), we can set up an equation to find x...

x=38+79

x=117

Answer:

A) 20 represents the amount of money saved in one month or amount saved per month. This is the slope or rate of change of the function.

B) 50 represents the amount of money already present in the account when she starts saving. This is the y-intercept of the function.

C) It will take 5 weeks for her to save $150

Step-by-step explanation:

A) 20 represents the amount of money saved in one month or amount saved per month. This is the slope or rate of change of the function.

B) 50 represents the amount of money already present in the account when she starts saving. This is the y-intercept of the function.

C) The time to reach $150

150 = 20(w) + 50

20(w) = 150 - 50

20w = 100

w = 100/20

w = 5

It will take 5 weeks

Answer:

A. 1.06

B. $6,784

Step-by-step explanation:

I = A - P = $384.00

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 6%/100 = 0.06 per year.

Solving our equation:

A = 6400(1 + (0.06 × 1)) = 6784

A = $6,784.00

The total amount accrued, principal plus interest, from simple interest on a principal of $6,400.00 at a rate of 6% per year for 1 year is $6,784.00.

Answer:

$18.00

Step-by-step explanation:

If the meal is $15.00, 20% of that meal's cost would be $3.00.

$15.00 * .20 = $3.00

Adding the tip to the meal's cost will give you a total cost of $18.00.

Answer:

A&B because they are not intersecting.

Answer:

Step-by-step explanation:

(x° - 38°) + x + 90° + 90° = 360°

(The sum of the interior angles of any quadrilateral is 360°)

[tex](x - 38) + x + 90 + 90 = 360 \\ x - 38+ x + 180 = 360 \\ x + x + 180 - 38 = 360 \\ 2x + 142 = 360 \\ 2x = 360 - 142 \\ 2x = 218 \\ \frac{2x}{2} = \frac{218}{2} \\ x = 109 \\ [/tex]

The total angle measures a quadrilateral has is 360 degrees and in the problem, we are told that two of the angles are both 90 degrees. So thats 180 degrees out of the way and now we have x+(x-38)=180 which is 2x-38=180 then you add 38 to both sides to get rid of the 38 on the left side and then you end up with 2x=218 so you have to divide both sides by 2 to remove the 2 from x and you would get x=109
