B. √3
C. √3/2
D. 1/√3

Answer:

24 cup cakes

Step-by-step explanation:

Karim uses. Total of 20 cup of batter to make x cupcakes and a cake. He uses 2/3 cups of batter for each cupcake and 4 cups of batter for the cake. How many cupcakes x can karim make if he uses all the batter

Let us represent:

Number of cup cakes = x

Number of cakes = y

x + y = 20 cups of batter

x + y = 20...... Equation 1

x = 20 - y

2/3 cups of batter for each cupcake and 4 cups of batter for the cake

Number of cups of batter for the cupcakes

= 20 - 4

= 16 cups of batter is used for the chop cakes

2/3 cups of batter for each cupcake

Hence:

2/3 cups of batter = 1 cup cakes

16 cups of batter = x

Cross Multiply

2/3 x x = 16

x = 16 ÷ 2/3

x = 16 × 3/2

x = 24 cup cakes

AND THE OTHERS

Answer:

y = -1/3 x + 1/3

Step-by-step explanation:

The red line passes through points (0, 2) and (2, 8).

The slope of the red line is (8 - 2)/(2 - 0) = 6/2 = 3

The slope of the perpendicular line is -1/3, and it passes through point (1, 0).

y = mx + b

y = -1/3 x + b

0 = (-1/3)(1) + b

b = 1/3

y = -1/3 x + 1/3

Answer:

12 ft

Step-by-step explanation:

Write and solve an equation of ratios:

 6 ft        4 ft

-------- = --------

 18 ft        w

Cross multiplying, we get:  6w = 72 ft^2, so w = 12 ft

Answer:

12ft

Step-by-step explanation:

Since a 4ft pole casts a 6ft long shadow that means for every 2ft of height the shadow is 3ft. Now the shadow is 18ft long so you do 18 / 3 = 6. To find the walls height you do 6 * 2 = 24.

Answer:

800

Step-by-step explanation:

In order to get the new population of bacteria in 690 minutes, you have to know how often the bacteria will divided in the time frame. So, you have to divide 690 minutes by 230 minutes.

The bacteria will double its colony 3 times in 690 minutes.

Therefore, the population of bacteria will be 800 in 690 minutes.

Answer:

1.028

Step-by-step explanation:

The original amount is 100%

Add 2.8% to 100% = 102.8%

Now divide by 100 to find the decimal multiplier

102.8 ÷ 100 = 1.028

Answer:

Sarah would have to by 4 sessions, and then the total cost of both gyms will be equal.

Step-by-step explanation:

Step-by-step explanation:

According to the problem, At Silver Gym is $25 per month, and $30 per personal training session. At Fit Factor is $65 per month and $20 per personal training session.

So, basically, each expression would be

At Silver Gym: 25 + 30x

At Fit Facto: 65 + 20x

To know the number of personal training sessions Sarah would have to buy to make them equal, we have to equalize these expressions and solve for x

25 + 30x = 65 + 20x

30x - 20x = 65 - 25

10x = 40

x = 4

Therefore, Sarah would have to by 4 sessions, and then the total cost of both gyms will be equal.

Notice that the variable is with the personal training sessions, you have to do that because a membership won't variate since the problem specifies the period of 1 month, however in one month, the number of personal training sessions do variate.

Answer:

Hence x =  60 and y = 50

e = 85 degrees

f = 158 degrees

Step-by-step explanation:

1) The sum of the interiror angle of the triangle is equal to the exterior

Given

Interior angles = y and 70

Exterior angle = 120 degrees

According to the law;

y + 70 = 120

y = 120-70

y = 50°

Sum of angle in the triangle is 180

x + y + 70 = 180

x + 50 + 70 = 180

x + 120 = 180

x = 180-120

x = 60

Hence x =  60 and y = 50

2) The sum of angles on a straight line is 180 degrees

40 + 55 + e = 180

95 + e = 180

e = 180 - 95

x = 85 degrees

3) Sum of angle at a point is 360 degrees

Hence 130 + 36.8 + 35.2 + f= 360

130 + 72 + f = 360

202 + f = 360

f = 360 - 202

f = 158 degrees

Answer:

y=5/16-11/16x

Step-by-step explanation:

16y=5-11x

divide by 16 on both sides

y=5/16-11/16x

Answer:

Answer:

d

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

So to do this problem, first find the area of the figure before you apply the scale factor, and then multiply that by 49. The reason you multiply it by 49 and not 7 is because you're multiplying both the length and the width of the figure by 7, so you have 7 * 7 = 49.

The area of the figure to start is 10 (you can find this by simply counting the blocks).

Then, 10 * 49 = C. 490 units squared.

hope that makes sense!
