Answer:

6 2/3 lbs of each

Step-by-step explanation:

.10x + .35x = 15(.20)

.45x = 3

x = 3/4.5

x = 6.67

Answer:

Step-by-step explanation:

[.1x+.35(15-x)]/15=.2

.1x+5.25-.35x=3

-.25x+5.25=3

-.25x=-2.25

x=9

So he will use 9lbs of 10% and 6lbs of 35%.

Answer:

904.32 ft^3

Step-by-step explanation:

Sphere Volume Formula: [tex]\frac{4}{3}[/tex][tex]\pi r^{3}[/tex]

Plug in the numbers:

[tex]\frac{4}{3}\pi 6^{3}[/tex]≅904.78

Answer and Step-by-step explanation:

[tex]-3y^{9}[/tex]

This value above is ONE term. Even though it is made up of more values and stuff, it is all one term BECAUSE they are all connect, so the -3 is with the y by multiplication, and the 9 is with -3y as an exponent of y.

Answer:

The values of [tex]f[/tex] and [tex]g[/tex] are, respectively:

[tex]f = 6\,cm[/tex], [tex]g = 8\,cm[/tex]

Step-by-step explanation:

The area of the triangle ADE is:

[tex]A_{ADE} = 60\,cm^{2}-48\,cm^{2}[/tex]

[tex]A_{ADE} = 12\,cm^{2}[/tex]

The area of the triangle is defined by the following formula:

[tex]A_{ADE} = \frac{1}{2}\cdot AD\cdot DE[/tex] (1)

If we know that [tex]A_{ADE} = 12\,cm^{2}[/tex] and [tex]DE = 4\,cm[/tex], then the length of the line segment [tex]AD[/tex] is:

[tex]AD = \frac{2\cdot A_{ADE}}{DE}[/tex]

[tex]AD = 6\,cm[/tex]

And the area of the rectangle is:

[tex]A_{ABCD} = AD\cdot CD[/tex] (2)

If we know that [tex]A_{ABCD} = 48\,cm^{2}[/tex] and [tex]AD = 6\,cm[/tex], then the length of the line segment [tex]CD[/tex] is:

[tex]CD = \frac{A_{ABCD}}{AD}[/tex]

[tex]CD = 8\,cm[/tex]

Hence, the values of [tex]f[/tex] and [tex]g[/tex] are, respectively:

[tex]f = 6\,cm[/tex], [tex]g = 8\,cm[/tex]

3x1/12= 3/12

3x1/2= 3/12

Answer:

5

Step-by-step explanation:

The common ration can be found by dividing the 2nd number from the 1st number:

250 / 50

which equals 5

250 / 50 = 5

         you can do this by any number, for example:

         50 / 10 =5

         10 / 2 = 5

Answer:

The order of fruit from least to greatest weight is -

Apple , pear, navel orange, grapefruit

Step-by-step explanation:

P.S - The exact question is -

Given - Sophia buys an apple that weighs 0.45 pound, a grapefruit that weighs [tex]\frac{3}{4}[/tex] pound, a navel orange that weighs [tex]\frac{5}{8}[/tex] pound, and a pear that weighs 0.5 pound.

To find - What is the order of the fruit from least weight to the greatest weight ?

Proof -

Weight of apple = 0.45 pound

Weight of grapefruit = [tex]\frac{3}{4}[/tex] pound = 0.75 pound

Weight of navel orange = [tex]\frac{5}{8}[/tex] pound = 0.625 pound

Weight of a pear = 0.5 pound

As,

0.45 < 0.5 < 0.625 < 0.75

So, The order of fruit from least to greatest weight is -

Apple , pear, navel orange, grapefruit

Answer:

2290 trees

Step-by-step explanation:

Given data

Let the total number of trees be x

62% of the total trees x is 1420 trees

mathematically

62/100x= 1420

0.62x= 1420

divide both sides by 0.62

x= 1420/0.62

x= 2290.32

To the nearest whole tree= 2290 trees

Answer:

D. 157.5

Step-by-step explanation:

Formual for sum of interior angles

so 14*180=2520

but that is the sum

divide that by 16 (2520/16) = 157.5

Answer:

Answer:

100 degrees

Step-by-step explanation:

hi again,

By the linear pair theorem, Angle B + Angle E will equal 180 degrees

Angle B + 128 = 180

Angle B = 52

By the triangle Sum Theorem, Angle A + Angle B + Angle C = 180

48 + 52 + Angle C = 180

100 + Angle C = 180

Angle C = 80

Like I said, by the linear pair theorem, Angle C + Angle F will equal 180 degrees

80 + Angle F = 180

Angle F = 100

Answer:

Step-by-step explanation:

which number do you want solved?

Answer:

96

Step-by-step explanation:

first off you know that it is a square pyramid, so you can assume that all base lengths are 6.

i am going to find the base first. it is 36 because 6*6-36 save this in your mental memory

next, we have to find the 4 triangles

we know that they are 5 by 6 but you have to divide them by 2

so 30/2=15 and there are 4 of them

15*4=60

now add together 60 and 36 and you get 96

hope this helps!

Answer:

2.25 cups of sugar

Step-by-step explanation:

2 dozen = 4 1/2 = 4.5

which means... 4.5/2 = 1 dozen

1 dozen = 4.5/2 = 2.25

a) We were told that relationship between the value of the car and its age is linear. This means that it can be represented with a linear equation such as

y = mx + c

y is the dependent variable and in this case, it is the value of the car, V

x is the independent variable and in this case, it is the age of the car, a

The above equation is the slope intercept form equation where

m represents slope

c represents y intercept

The formula for determining slope is expressed as:

m = (y2 - y1)/(x2 - x1)

We were told that a 5 year old car is worth 14000. This means that

When x1 = 5, y1 = 14000

Also, the same car is worth 11400 after 2 years. This means that the car is worth 11400 after 7 years. Thus,

when x2 = 7, y2 = 11400

Thus,

slope, m = (11400 - 14000)/(7 - 5) = - 2600/2

m = - 1300

We would find the y intercept, c by substituting m = - 1300, x = 5 and y = 14000 into the slope intercept equation. Thus,

14000 = - 1300 * 5 + c

14000 = - 6500 + c

c = 14000 + 6500

c = 20500

Thus, by substituting m = - 1300 and c = 20500 into the slope intercept equation, the linear equation representng this scenario is

y = - 1300x + 20500

By replacing with the given variables,

V = - 1300a + 20500

b) When the car was new, it means that a = 0. By substituting a = 0 into the equation, we have

V = - 1300 * 0 + 20500

V = 20500

The value of the car was $20500 when it was new

Answer:

628.4cm²

Step-by-step explanation:

Find the diagram attached

Area of the semi circle = πr²/2

r is the radius = 10cm

Area of the semi circle = π(10)²/2

Area of the semi circle = 3.142(100)/2

Area of the semi circle = 314.2×2cm²

Area of the semi circle =628.4cm²

Hence the area of the semicircle is 628.4cm²

Answer:

{x,y} = {3,-2}

Step-by-step explanation:

Then the intersection point is (3, -2). Then the solution of the equations will be (3, -2).

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

x/a + y/b = 1

Where 'a' is the x-intercept of the line and ‘b’ is the y-intercept of the line.

The equations are given below.

5x + 7y = 1

x + 4y = -5​

Convert the equation into an intercept form. Then we have

From equation 1, then we have

5x + 7y = 1

x / (1/5) + y / (1/7) = 1

From equation 2, then we have

x + 4y = -5​

x / (-5) + y / (-5/4) = 1

The lines are drawn below.

Then the intersection point is (3, -2). Then the solution of the equations will be (3, -2).

Answer:

t + 2p = cost of 1 family member

Step-by-step explanation:

Because there are 5 family members who buy 1 ticket and 2 boxes of popcorn, we must multiply the cost of one family member by five .

5(t + 2p) = total cost of the whole family.

We can distribute 5 and the above equation will become.

5t + 2(5)p ⇒ 5t + 10p = total cost of the whole family.

Hope that helps! :)

Answer:

Step-by-step explanation:

t + 2p = cost of 1 family member

since there are 5 family members who bought one ticket and 2 popcorn, we simply multiply the cost of 1 family member by 5.

5(t + 2p) = total cost of the whole family.

We can distribute 5 and the above equation will become.

5t + 2(5)p ⇒ 5t + 10p = total cost of the whole family.

Answer:

3.5

Explanation:

Take any two points of the line and simply use the formula slop = y2-y1/x2-x1

Two points that I consider

(x1, y1) = (5,0)

(x2,y2) = (7,7)

Now using the above mentioned formula,

y2-y1/x2-x1 = 7-0/7-5 = 7/2= 3.5

Hence slop of line is 3.5
