Lucy and JoJo need to make 140 cupcakes for the school dance. Lucy made 35 of the cupcakes JoJo made 42 cupcakes What fraction of the cupcakes do Lucy and JoJo still need to make? (Use / as a fraction bar.)

Answers

Answer:

16/35

Step-by-step explanation:

From the question we are given:

total number of cupcakes needed for the school dance = 140 cupcakes

Lucy made 35cupckes

JoJo made 42 cupcakes

Total cupcakes made by JoJo and Lucy = 35+42 = 76cupcakes

Remaining cupcakes still needed to be made = 140 - 76 = 64cupckes

Fraction of the cupcakes that Lucy and JoJo still need to make = 64/140

Fraction of the cupcakes that Lucy and JoJo still need to make = 16/35

Hence the fraction of the cupcakes that Lucy and JoJo still need to make is 16/35

Step-by-step explanation:

There is a common ratio between consecutive terms, that is

2 ÷ 1 = 4 ÷ 2 = 8 ÷ 4 = 2

Thus to obtain any term in the sequence multiply the previous term by 2

a₅ = a₄ × 2 = 8 × 2 = 16

a₆ = a₅ × 2 = 16 × 2 = 32

The probability that Brian wins a raffle is given by the expression n n + 2 . Write down an expression, in the form of a combined single fraction, for the probability that Brian does not win.

Answers

Answer:

[tex]\frac{2}{n+2}[/tex]

Step-by-step explanation:

Given

Let the total probability be 1

Probability that Brian wins a raffle  = n/n+2

Probability that Brian does not win a raffle = 1 - Probability that Brian wins a raffle

Probability that Brian does not win a raffle = 1 - (n/n+2)

Probability that Brian does not win a raffle = [tex]\frac{n+2-n}{n+2}[/tex]

Probability that Brian does not win a raffle = [tex]\frac{2}{n+2}[/tex]

Hence required fraction is  [tex]\frac{2}{n+2}[/tex]

Q7. 240Q8. 25°Q9. 70°

Step-by-step explanation:

Q7.

The shortest sides are corresponding in similar triangles

One has side length of 5, another one is 20

Scale factor is:

20/5 = 4

Since perimeter is sum of 3 sides and each side has 4 times difference, the perimeter will have 4 times the difference. So it is:

60*4 = 240Q8.

Dilation doesn't affect angle measures. A and W are corresponding angles and they measure the same.

m∡A = m∡Wx + 20 = 5x5x - x = 204x = 20x = 5

m∡W = 5x = 5*5 = 25°

Q9.

Dilation doesn't affect angle measures. B and M are corresponding angles and they measure the same.

m∡B = m∡M2x + 30 = 3x + 103x - 20 = 30 - 10x = 20

m∡B = 2x + 30 = 2*20 + 30 = 70°

3. What % of 100 is 13?

Answers

Answer:

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 13 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 13 is 100%, so we can write it down as 13=100%.

4. We know, that x is 100% of the output value, so we can write it down as x=100%.

5. Now we have two simple equations:

1) 13=100%

2) x=100%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

13/x=100%/100%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 100% of 13

13/x=100/100

(13/x)*x=(100/100)*x       - we multiply both sides of the equation by x

13=1*x       - we divide both sides of the equation by (1) to get x

13/1=x

13=x

x=13

now we have:

100% of 13=13

The center of a circle is at (2, −5) and its radius is 12.

What is the equation of the circle?


(x−2)2+(y+5)2=144

(x+2)2+(y−5)2=24

(x−2)2+(y+5)2=24

(x+2)2+(y−5)2=144

Answers

Answer:

The equation of the circle is (x - 2)² + (y + 5)² = 144A

Step-by-step explanation:

The form of the equation of the circle is (x - h)² + (y - k)² = r², where

r is the radius of the circleh, k are the coordinates of the center of the circle

Let us solve the question

∵ The center of the circle is at (2, -5)

→ From the rule above

h = 2 and k = -5

∵ The radius of the circle is 12

r = 12

→ Substitute the values of r, h, and k in the form of the equation above

∵ (x - 2)² + (y - -5)² = (12)²

∴ (x - 2)² + (y + 5)² = 144

The equation of the circle is (x - 2)² + (y + 5)² = 144

Step-by-step explanation:

Two linear equations are represented by using the tables below.

A 2-column table with 4 rows is titled Equation B. Column 1 is labeled x with entries negative 6, negative 3, 3, 6. Column 2 is labeled y with entries negative 4, negative 2, 2, 4.

The data points for equation A are plotted on the coordinate plane below and are connected by using a straight line.

On a coordinate plane, a line goes through points (negative 5, negative 4), (negative 2, negative 1), (0, 1), (1, 2).

What is the solution to the system of equations?
(–6, –4)
(–5, –4)
(–3, –2)
(0, 1)

Answers

Answer:

(–3, –2)

Step-by-step explanation:

A linear equation is an equation in the form y = mx + b, where m is the slope of the line and b is the y intercept.

Equation A is represented by the points:

x:    -5      -2        0          1

y:    -4       -1         1           2

Equation A can be gotten by picking any two pair of points. Let us use (-5, -4) and (0, 1). We use this formula:

[tex]y- y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-(-4)=\frac{1-(-4)}{0-(-5)} (x-(-5))\\\\y +4=x+5\\\\y=x+1[/tex]

Equation B is represented by the points:

x:    -6      -3        3          6

y:    -4       -2         2          4

Equation B can be gotten by picking any two pair of points. Let us use (-6, -4) and (3, 2). We use this formula:

[tex]y- y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-(-4)=\frac{2-(-4)}{3-(-5)} (x-(-6))\\\\y +4=\frac{2}{3}( x+6)\\\\y+4=\frac{2}{3} x+4\\\\y=\frac{2}{3}x[/tex]

The solution to the system of equations is gotten by solving y = x + 1 and y = (2/3)x simultaneously.

Substitute y = (2/3)x in y = x + 1:

(2/3)x = x + 1

2x = 3x + 3

x = -3

Put x = -3 in y = (2/3)x

y = (2/3) (-3) = -2

Hence (-3, -2) is the solution
