A fruit punch recipe call for 30 cups of orange juice and 18 cups of pineapple juice. If you only have 1 cup of orange juice, how many cups of pineapple should you use.

Answers

Answer:

You should use 0.6 cups of pineapple juice if you only have 1 cup of orange juice.

Step-by-step explanation:

With the information provided about the recipe, you can use a rule of three to find the cups of pineapple you should use if you only have 1 cup of orange juice given that the recipe calls for 30 cups of orange juice and 18 cups of pineapple juice:

30 cups of orange juice → 18 cups of pineapple juice

 1 cup of orange juice    →                    x

x=(1*18)/30=0.6 cups of pineapple juice

According to this, the answer is that you should use 0.6 cups of pineapple juice if you only have 1 cup of orange juice.

You are planning your vacation and trying to figure out the total number of miles you will be traveling on a round trip from Portland, Oregon to Denver, Colorado, and back to Portland, Oregon. The scale for the map you are consulting shows that 1 inch = 4 miles. Measuring, you find that you will be traveling 31412 inches for the one-way trip. What is the total number of miles you will be traveling during the entire round trip?

Answers

Answer:

31,417 miles i think I hope it will help

The total number of miles you will be traveling for the entire round trip is 125650 miles.

What is metric conversion?

Metric Conversion refers to the conversion of the given units to desired units for any quantity to be measured.

The question states that 1 inch = 4 miles. Therefore, if you multiply 31412 inches by 4, you will get the total number of miles you will be traveling for the round trip.

31412 × 4 = 125650

Therefore, the total number of miles you will be traveling for the entire round trip is 125650 miles.

1/4 of a pizza was broccoli and half was mushroom and 1/4 was three cheeses. George ate 1/3 of the broccoli part and 1/3 of the mushroom part and 1/2 of the 3 cheese part. How much of the total pizza did he eat?

Answers

1/4 = broccolis
1/2 = mushroom
1/4= 3 cheeses

George ate a 1/3 of the broccoli & 1/2 of the 3 cheeses.

1/3 of 1/4 broccoli= ?
1/2 of 1/4 3 cheeses = ?
1/3 of 1/2 mushrooms= ?

(1/3)/(1/4)= 5/6
(1/2)/(1/4)= 1/6
(1/3)/(1/2)= 1/6

5/6+1/6+1/6= 7/18

He ate 7/18 of the whole pizza.

He ate 5/6 of the broccoli pizza & 1/6 of the 3 cheeses.

By Factoring And Using Quadratic Formula x raise to two minus 10x is equals to negative 21

Answers

Answer:

[tex]x =3[/tex] or [tex]x = 7[/tex]

Step-by-step explanation:

Given

[tex]x^2 - 10x = -21[/tex]

Required

Solve by factoring & quadratic formula

By Factoring:

[tex]x^2 - 10x = -21[/tex]

Equate to 0

[tex]x^2 - 10x +21 = 0[/tex]

Expand:

[tex]x^2 - 7x -3x+21 = 0[/tex]

Factorize:

[tex]x(x-7)-3(x-7) = 0[/tex]

[tex](x-3)(x-7) = 0[/tex]

[tex]x -3 = 0[/tex] or [tex]x - 7 = 0[/tex]

[tex]x =3[/tex] or [tex]x = 7[/tex]

By quadratic

[tex]x^2 - 10x = -21[/tex]

Equate to 0

[tex]x^2 - 10x +21 = 0[/tex]

For

[tex]ax^2 + bx + c = 0[/tex]

x is solved using:

[tex]x = \frac{-b\±\sqrt{b^2-4ac}}{2a}[/tex]

where

[tex]a = 1[/tex]; [tex]b = -10[/tex]; [tex]c = 21[/tex]

So:

[tex]x = \frac{-(-10)\±\sqrt{(-10)^2-4*1*21}}{2*1}[/tex]

[tex]x = \frac{10\±\sqrt{100-84}}{2}[/tex]

[tex]x = \frac{10\±\sqrt{16}}{2}[/tex]

[tex]x = \frac{10\±4}{2}[/tex]

Split

[tex]x = \frac{10+4}{2}[/tex] or [tex]x = \frac{10-4}{2}[/tex]

[tex]x = \frac{14}{2}[/tex] or [tex]x = \frac{6}{2}[/tex]

Histogram attached

Answer and explanation:

To find the center of the distribution, we find the mean of the distribution.

Mean= sum of all values/number of values

To calculate the mean of the distribution using the histogram(attached) with given frequencies, we find the mid point of each class and multiply by its frequency to get the sum of the values(estimated) and then divide by the number of values(sum of the frequencies of the classes)

midpoint of 50-60=50+60/2=55

midpoint of 70-80=150/2= 75

midpoint of 80-90=170/2=85

midpoint of 90-100=190/2=95

midpoint of 100-110=210/2=105

Midpoint of 110-120=230/2=115

Midpoint of 120-130=250/2=125

Midpoint of 130-140=270/2=135

Midpoint of 140-150=290/2=145

Midpoint of 150-160=310/2=155

Sum of the values= 55*frequency= 55*3+75* 2+85*1+95*7+105*17+115*29+125*10+

135*2+145*3+155*3

Sum of all values =8605

Number of values= 3+2+1+7+17+29+10+2+3+3=77

Mean= 8605/77= 111.753

Therefore the center of the distribution is between 110 and 120 calories.

Benjamin decided to himself to breakfast at Seva restaurant he ordered chocolate milk that cost $3.25 then he wants the bio as many pan cakes as he can but he wants to be able to be at most $30 before tax the restaurant only sells pancakes in stacks oh for pancakes cakes for $5.50. Let S represent the number of stacks of pancakes that Benjamin buys which any inequality describe this scenario

Answers

Answer: 3.25 + 5.50s ≤ 30

Step-by-step explanation:

The following information can be gotten from the question.

Cost of chocolate milk = $3.25

Cost of stack pancake = $5.50

Maximum amount to be spent by Benjamin = $30

Number of stacks of pancakes to be bought = s

First, we need to calculate the stacks of pancakes that Benjamin can buy. This will be:

= $5.50 × s

= 5.50s

Therefore, the total money that Benjamin will spend will be:

= 3.25 + 5.50s

Since he wants to be able to be at most $30 before tax, the inequality can be written as:

= 3.25 + 5.50s ≤ 30

Arranging from longest (at top) to shortest (at bottom)

DE

Step-by-step explanation:

We need to place the sides of triangle DE, DF and EF from longest to shortest.

The triangle has longest side that is opposite to the largest angle

We know two angles < E= 61° , <F= 59° we need to find <D

Sum of angles of triangle = 180°

So, 61°+59°+<D=180°

120°+<D=180°

<D=180°-120°

<D=60°

So, the largest angle is <E= 61°

The longest side must be opposite to <E so, the side is DF

The second largest angle is <D=60° so, second side will be EF

The smallest angle is <F=59° so, third (shortest) side will be DE

Arranging from longest (at top) to shortest (at bottom)

Find the slope of each line in the figure.
Slope of p =

Slope of q =

Slope of r =

Slope of m =

Slope of n =

Answers

Answer:

slope of p= -7/12

slope of q= -3/6.8

slope of r= -16/6.4

slope of m= 6.2/15.5

slope of n= 6.8/17

Step-by-step explanation:

The slopes of the line are given as 2.5 for p and q and -2.5 for r, m and n respectively.

What is the slope of straight line?

The slope of a straight line is the tangent of the angle formed by it with the positive x axis as the reference.

The negative slope indicates the rate of decrease while the positive shows the rate of increase.

The slope of the given lines can be obtained as follows,

(a) In order to find slope of line p,

Use the formula m = (x₂ - x₁)/(y₂ - y₁) and substitute the corresponding values to get,

m = (-3 - 8)/(0.4 - (-4))

⇒ m = -2.5

(b)  In order to find slope of line q,

Use the formula m = (x₂ - x₁)/(y₂ - y₁) and substitute the corresponding values to get,

m = (13 - 0)/(6.8 - 12)

⇒ m = -2.5

(c)  In order to find slope of line r,

Use the formula m = (x₂ - x₁)/(y₂ - y₁) and substitute the corresponding values to get,

m = (13 - (-3))/(6.8 - 0.4)

⇒ m = 2.5

(d) In order to find slope of line m,

Use the formula m = (x₂ - x₁)/(y₂ - y₁) and substitute the corresponding values to get,

m = (-15.5 - 0)/(0 - 6.2)

⇒ m = 2.5

(e)  In order to find slope of line n,

Use the formula m = (x₂ - x₁)/(y₂ - y₁) and substitute the corresponding values to get,

m = (-5 - 12)/(- 6.8 - 0)

⇒ m = 2.5

Hence, the slopes of first two lines are 2.5 and of the remaining three are 2.5.

(4marks)

Answers

Answer:

When s = 20, r = 9

Step-by-step explanation:

Given,

s is directly proportional to (r + 1)

s = k(r + 1)

(k is the constant of proportionality)

When s = 8,

8 = k(3 + 1)

8 = k(4)

8 = 4k

8/4 = k

2 = k

When s = 20,

20 = 2(r + 1)

20 = 2r + 2

20 - 2 = 2r

18 = 2r

18/2 = r
