Answer:

Step-by-step explanation:

Ratio of cakes baked by Calvin and Susie = 3 : 7

Cakes baked by Calvin = 3x

Cakes baked by Susie = 7x

Cakes baked by Calvin = Cakes baked by Susie - 60

3x = 7x - 60

7x - 60 = 3x

7x        = 3x  + 60

7x - 3x = 60

      4x  = 60

        x = 60/4

x = 15

Cakes baked by Calvin = 3*15 = 45

Cakes baked by Susie = 7 *15 = 105

Total cakes baked = 45 + 105 = 150

They both baked 150 cakes altogether.

Answer: She would have to visit the movie theater 10 times.

Step-by-step explanation:

Step-by-step explanation:

I am not sure what the actual question is.

the general function for the amount of gathered reward points p with v visits to the theater is

p(v) = 14.5×v + 40 (40 starting points, 14.5 points per visit)

to know how many visits are needed for a certain amount of points (185) we need to solve that equation for v :

185 = 14.5×v + 40

145 = 14.5×v

v = 145/14.5 = 10

so, she needs at least 10 visits to gather the desired 185 points for a free ticket.

but that applies only to the first free ticket.

after that the function behavior kind of changes, because we have no more starting points :

so to get 2×185 = 370 points for 2 free tickets she will need

370 = 14.5×v + 40

330 = 14.5×v

v = 330/14.5 = 22.75862069...

we need to round up to the next whole number (because there can be no "part-visits").

so, she will need 23 visits for 2 free tickets (that means 13 more visits for the second free ticket).

Step-by-step explanation:

1.A+B=61

2.41+25=61

Answer:

acceleration,A = 7

Step-by-step explanation:

F = kA

First expression: 45 = 5k, k = 9

therefore, when F = 63, A = 63/9 = 7

The Pythagorean theorem is the idea that the sum of the two legs which are both squared is equal to the hypotenuse's length squared.

     *look at the image I attached for a better explanation

By looking at the picture, we are missing the leg's length, and by using the Pythagorean theorem, we get the equation

    [tex]?^2+5^2 = 13^2\\?^2 + 25 = 169\\?^2 = 144\\? = 12[/tex]

Thus the missing side length is 12 cm

Answer:

771 is the absolute value of -771.

Step-by-step explanation:

The absolute value is the distance of that number from 0. Therefore, negative or not, the number shown will always be the positive number that it is.

Examples:

|-8| = 8.

|2|=2

|-9912|=9912

|236|=236

Continued explanation:

Because the absolute value is the distance of that number from zero, the value will always be positive. And then the distance is going to be the same number.

Answer: [tex]\frac{3}{2}x+y=-\frac{17}{2}[/tex]

Step-by-step explanation:

The standard form of a linear equation is [tex]ax+by=c[/tex]

So we need to solve for c

Start by simplifying everything in the equation

[tex]y+7=-\frac{3}{2} (x+1)[/tex]

Use the Distributive Property

[tex]y+7=-\frac{3}{2}x-\frac{3}{2}[/tex]

Now subtract 7 from both sides

[tex]y+7=-\frac{3}{2}x-\frac{3}{2}\\y+7-7=-\frac{3}{2}x-\frac{3}{2}-7\\y=-\frac{3}{2}x-\frac{17}{2}[/tex]

Add [tex]\frac{3}{2} x[/tex] to both sides

[tex]y+\frac{3}{2}x=-\frac{3}{2}x+\frac{3}{2}x-\frac{17}{2}\\\frac{3}{2}x+y=-\frac{17}{2}[/tex]

NOTE: [tex]-\frac{17}{2}[/tex] simplifies to -8.5 if you find that more desirable

The number of minutes that would pass before they were 1870 feet apart is 5.47 minutes

Since they are initially 10 feet apart, their total distance apart after t minutes is D = d + 10 + d'

D = 180t + 10 + 160t

D = 340t + 10

Making t subject of the formula, we have

t = (D - 10)/340

Since they are 1870 feet apart after t minutes, D = 1870 feet.

t = (D - 10)/340

t = (1870 - 10)/340

t = 1860/340

t = 5.47 minutes

So, the number of minutes that would pass before they were 1870 feet apart is 5.47 minutes

Step-by-step explanation:

Answer:

Formula for area of circle (since two semi circles form a full circle);

a = π[tex]r^{2}[/tex]

First, figure out our radius,

D/2 = Radius

10/2 = 5 is our radius.

Plug in your values:

a = π[tex]r^{2}[/tex]

a = 3.14(5^5)

a = 3.14(25)

a = 78.5 is the area of the two semi circles.

Now the square;

A = L x W

A = 10(10)

A = 100.

Add your areas;

78.5 + 100

= 178.5 mm2

Step-by-step explanation:

Working with the top equation, subtract 2x from both sides.

y = 9 - 2x

Put this value for y in the second equation

3x - 4(9 - 2x) = 8                 Remove the brackets

3x -36 + 8x = 8                   Add 36 to both sides

3x + 8x = 8 + 36                 Combine

11x = 44                               Divide by 11

x = 4

2x + y = 9

2*4 + y = 9                          

8 + y = 9                              Subtract 8 from both sides

y = 9-8

y = 1

x = 8

Step-by-step explanation:

Using the equation 5x = 4y, if y = 10, what is x?

5x = 4y

5x = 4(10) <== substitute 10 for y

5x = 40

The smaller number is 18.

Step-by-step explanation:

Let larger number = x and  smaller number = \dfrac{2}{3} x32x

To find, the smaller number = ?

According to question,

x+\dfrac{2}{3} x=45x+32x=45

⇒ \dfrac{3x+2x}{3} =4533x+2x=45

⇒ 5x=45\times 35x=45×3

⇒ 5x=1355x=135

⇒ x =\dfrac{135}{5} =27x=5135=27

∴ Smaller number =\dfrac{2}{3} \times 27=2\times 9 =18=32×27=2×9=18
