Answer: There are 80 dimes and 120 nickels.

Step-by-step explanation: Now check to make sure it's right. How much is 120 nickels worth? How much is 80 dimes?

Answer:

The answer is 144

Step-by-step explanation:

The solution to the equation is y = 5.

Therefore, the correct answer is "O y = 5."

Option C.

Here,

Let's solve the equation step by step to find the value of y:

Combine the y terms on the left side of the equation:

y + 3y + 6 = 26

Combine the y terms on the left side of the equation:

4y + 6 = 26

Move the constant term to the other side of the equation:

4y = 26 - 6

Simplify the right side:

4y = 20

Now, solve for y by dividing both sides of the equation by 4:

y = 20 / 4

y = 5

So, the solution to the equation is y = 5.

Therefore, the correct answer is "O y = 5."

Option C.

Answer:

$39

Step-by-step explanation:

Given parameters:

Cost of ingredient  = $9.75

Number of people  = 6 people

Unknown:

How much will it cost to serve 24 people  = ?

Solution:

To solve this problem, let us find the rate of each recipe per person;

 Rate  = [tex]\frac{Number of people }{Cost of ingredient}[/tex]

Insert parameters and solve;

 Rate = [tex]\frac{6}{9.75}[/tex]   = 0.62people/$

For 24 people, it will cost;

Answer:

i) OC=a+b

ii) BA=a-b

iii)CA=-b

Step-by-step explanation:

i) because it is a parallelogram AC=OB and therefore AC=b

to find OC you do OA+AC which is a+b

OC=a+b

ii) to find BA you do BO+OA

BO=-b as it is the opposite direction

OA=a

so therefore BA=a-b

iii)CA is the opposite of AC which was b so CA=-b

Answer:

x≥-2

y<3

y≥x+3

Step-by-step explanation:

For x≥-2 the line is passing through -2 on the X axis

For y<3 the dotted line is passing through 3 on the y axis and as it is dotted it is just less than

For y≥x+3 the line is passing through -3 on the x axis and 3 on the y axis so it must be y=x+3. Then you apply the inequality so it becomes y≥x+3

The inequalities to describe the shaded area on the grid​ are

[tex]\rm \bold {x\geq -2}\\\bold{y<3}\\\\bold{y \geq\ x+3}[/tex]

The shaded area of the grid is surrounded by three lines the equations of all three lines are given as below in form of inequalities.

For a solid line the " equality"  is included but for a dashed line " equality" is not included.

x ≥ -2

y < 3

The equation of third line can be found out by writing standard form of straight line

[tex]\rm y = mx +c \\m = Slope \;of\; the\; line\\c = y\; axis \; intercept \; value[/tex]

As we can observe from the figure that the line passes through (0,3) and (-3,0) and hence we write the equation of line as

[tex]\rm y = (3-0) /(0-(-3)) ( x+3) \\y = 1\times x + 3\\y = x+3 \\So \; the\; inequality\; can \; be\; written\; as\\y\geq x+3[/tex]

Since the area above the line y = x+3 is of our concern hence greater than equal to sign is used.

So the inequality for third line is

[tex]\rm\bold{ {y\geq x+3}}[/tex]

The inequalities to describe the shaded area on the grid​

[tex]\rm \bold {x\geq -2}\\\bold{y<3}\\\\bold{y \geq\ x+3}[/tex]

Answer:

Psalm West is 1

Chicago West is 2

Saint is 4

North West is 7

Kim Kardashian has 4 children. North West is 5 years older than Chicago West. Psalm West is a year younger than Chicago West. Saint is twice as old as Chicago. If the sum of their ages is 14, how old is North West? Write an equation

Answer: North West would be 7 years old!

Explanation: How old is North West? This is the equation:

Their ages are...

1 + 2 + 4 = x

1 + 2 + 4 = 7

If the sum of their ages is 14 so...

14 (sum of ages) - 7 (total numbers of combined 3 West siblings)

14 - 7 = 7

Answer: The possible numbers of laps he will run today = 9

Step-by-step explanation:

Let [tex]n[/tex] = number of laps he will run today.

Given: Time taken for each lap = 5 minutes

Time taken for [tex]n[/tex] laps =[tex]5n[/tex]  minutes

If he runs at most 45 minutes, then

[tex]5n\leq45[/tex]

Divide both sides by 5 , we get

[tex]n\leq9[/tex]

Hence, the possible numbers of laps he will run today = 9

x = 30

m<Y = 60

m<Z = 60

m<X = 60

Step-by-step explanation:

All of this should add up to 180 so...

2x + 2x + 3x - 30 = 180 (collect like terms)

7x - 30 = 180 (add 30 on both sides)

7x = 210 (divide by 7 on both sides)

x = 30

2(30) = 60

3(30) - 30

90 - 30 = 60

Explanation:

"The product of 8 and" means 8 is going to be multiplied times another quantity. "...the sum of a number x and 3" means that 8 is going to be multiplied times (x+3).

This is represented by 8×(x+3), which simplifies to 8(x+3).

Answer:

[tex]Number\ of\ Committee = 6914880\ ways[/tex]

Step-by-step explanation:

Given

Total:

[tex]Freshmen= 7\\ Sophomores = 8\\ Juniors = 8\\ Seniors = 8[/tex]

Selection

[tex]Freshmen= 2\\ Sophomores = 3\\ Juniors = 4\\ Seniors = 5[/tex]

Required

Determine the number of selection

To do this, we make use of combination formula:

[tex]^nC_r = \frac{n!}{(n-r)!r!}[/tex]

For Freshmen, we have:

[tex]n = 7; r = 2[/tex]

[tex]^7C_2 = \frac{7!}{(7-2)!2!}[/tex]

[tex]^7C_2 = \frac{7!}{5!2!}[/tex]

[tex]^7C_2 = \frac{7 * 6 * 5!}{5! * 2 * 1}[/tex]

[tex]^7C_2 = \frac{7 * 6}{2}[/tex]

[tex]^7C_2 = \frac{42}{2}[/tex]

[tex]^7C_2 = 21[/tex]

For Sophomores, we have:

[tex]n =9;r=3[/tex]

[tex]^9C_3 = \frac{9!}{(9-3)!3!}[/tex]

[tex]^9C_3 = \frac{9!}{6!3!}[/tex]

[tex]^9C_3 = \frac{9 * 8 * 7 * 6!}{6! * 3 * 2 * 1}[/tex]

[tex]^9C_3 = \frac{9 * 8 * 7 }{6}[/tex]

[tex]^9C_3 = \frac{504}{6}[/tex]

[tex]^9C_3 = 84[/tex]

For Juniors, we have:

[tex]n = 8; r = 4[/tex]

[tex]^8C_4 = \frac{8!}{(8-4)!4!}[/tex]

[tex]^8C_4 = \frac{8!}{4!4!}[/tex]

[tex]^8C_4 = \frac{8 * 7 *6 * 5 * 4!}{4!*4 * 3 * 2 * 1}[/tex]

[tex]^8C_4 = \frac{8 * 7 *6 * 5}{4 * 3 * 2 * 1}[/tex]

[tex]^8C_4 = \frac{1680}{24}[/tex]

[tex]^8C_4 = 70[/tex]

For Seniors

[tex]n = 8; r = 5[/tex]

[tex]^8C_5 = \frac{8!}{(8-5)!5!}[/tex]

[tex]^8C_5 = \frac{8!}{3!5!}[/tex]

[tex]^8C_5 = \frac{8 * 7 *6 * 5!}{5! * 3 * 2 * 1}[/tex]

[tex]^8C_5 = \frac{8 * 7 *6}{3 * 2 * 1}[/tex]

[tex]^8C_5 = \frac{8 * 7}{1}[/tex]

[tex]^8C_5 = 56[/tex]

[tex]Number\ of\ Committee = Freshmen\ and\ Sophomores\ and\ Juniors\ and\ Seniors[/tex]

Answer:

the slope is -400

Step-by-step explanation:

In order to find the slope, we must use the slope equation

m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

where it was considerated 2 points of the line, i.e.,

(x_1,y_1) and (x_2,y_2)

In this case, we observe that there are 2 "easy" points,

(x_1,y_1)=(0,4000) and

(x_2, y_2)=(10,0)

By substituying these point in the slope equation, one has

m=[tex]\frac{0-4000}{10-0}[/tex]

m=[tex]\frac{-4000}{-10}[/tex]

Hence, m=-400.

Given:

Perimeter of a football field = 920 feet.

The width is 60 feet more than one-third of the length.

To find:

The dimensions of a football field.

Solution:

Let the length of the field be x.

Then, width = [tex]\dfrac{1}{3}x+60[/tex]

We know that,

[tex]Perimeter = 2( length + width)[/tex]

[tex]920 = 2(x+\dfrac{1}{3}x+60)[/tex]

[tex]920 = 2(\dfrac{4}{3}x+60)[/tex]

[tex]920 =\dfrac{8}{3}x+120[/tex]

Subtract both sides by 120.

[tex]920-120 =\dfrac{8}{3}x+120-120[/tex]

[tex]800 =\dfrac{8}{3}x[/tex]

Multiply both sides by 3.

[tex]2400 =8x[/tex]

Divide both sides by 8.

[tex]300 =x[/tex]

Now,

[tex]Length = 300\text{ feet}[/tex]

[tex]Width=\dfrac{1}{3}(300)+60[/tex]

[tex]Width=100+60[/tex]

[tex]Width=160\text{ feet}[/tex]

Therefore, the length and width of the football field are 300 feet and 160 feet respectively.
