Sam has a total of 43 quarters and nickels in her purse. If her change is worth $7.75, how many nickels and how many quarters does Sam have?
Warning: This is Algebra 1

Answers

Answer:

i need help with this too\

Step-by-step explanation:

Let q= the number of quarters
Let n=the number of nickels

q+n=43 This equations represents the total number of coins.
0.25q+0.05n=7.75 This equations represents her change totaling to $7.75.

Multiply the second equation by 100 to simplify the arithmetic.

q+n=43
25q+5n=775 Multiply the first equation by -5.

-5q-5n=-215
25q+5n=775 Add the two equation in which the n variable gets eliminated.
20q=560 Divide both sides by 20.

q=28 Substitute q=28 into the first equation and solve for n.
28+n=43
-28 -28
n=15 Therefore, she has 28 quarters and 15 nickels in her purse.

Hope this helps.

what you find 420% of 85 what are you looking for?​

Answers

Answer:

420% of 85 = 357

Step-by-step explanation:

85/x=100/420

(85/x)*x=(100/420)*x       - we multiply both sides of the equation by x

85=0.23809523809524*x       - we divide both sides of the equation by (0.23809523809524) to get x

85/0.23809523809524=x

357=x

x=357

A triangular pyramid and its net are shown. Rain uses the calculations below to conclude that the surface area of the triangular pyramid is 238.5 square inches. 3 x 10 x 13) + ( x 10 x 8.7) 3 (65) + 43.5 238.5 Is Rain correct? Use the drop-down menus to explain your reasoning.​

Answers

Answer:

Yes, Rain is correct

238.5 square inches

Step-by-step explanation:

Surface Area of a Triangular Pyramid,A = 1/2(a × b) + 3(1/2 × b × s)

= (1/2 × 10 × 8.7) + 3(1/2 × 10 × 13)

= 43.5 + 3(65)

= 43.5 + 195

= 238.5 square inches

The surface area of the triangular pyramid = 238.5 square inches

The surface area of the net of the triangular pyramid is 223.5 in². Rain is not correct.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

From the net attached:

Surface area = 3(1/2 * 10 * 12) + (1/2 * 10 * 8.7)

Surface area = 223.5 in²

The surface area of the net of the triangular pyramid is 223.5 in². Rain is not correct.

In ΔWXY, y = 88 cm, x = 85 cm and ∠X=70°. Find all possible values of ∠Y, to the nearest 10th of a degree.

Answers

Answer:

All possible values of ∠Y are 76.6° and 103.4°

Step-by-step explanation:

In Δ WXY

∵ x is the opposite side of ∠X

∵ y is the opposite side of ∠Y

→ By using the sine rule

∴ [tex]\frac{x}{sin(X)}[/tex] = [tex]\frac{y}{sin(Y)}[/tex]

∵ x = 85 and y = 88

∴ m∠X = 70°

→ Substitute them in the rule above

∴ [tex]\frac{85}{sin(70)}[/tex] = [tex]\frac{88}{sin(Y)}[/tex]

→ By using the cross multiplication

∴ 85 × sin(Y) = 88 × sin(70)

→ Divide both sides by 85

∴ sin(Y) = 0.9728582427

∴ m∠Y = [tex]sin^{-1}[/tex](0.9728582427)

∴ m∠Y = 76.62037845

→ Round it to the nearest tenth

∴ m∠Y = 76.6°

→ The other value of ∠Y is the obtuse angle supplement of ∠Y

∴ m∠Y = 180 - 76.6

∴ m∠Y = 103.4°

∴ All possible values of ∠Y are 76.6° and 103.4°

which of the ordered pairs is a solution of the following equation
5x-2y=20

Answers

We want to see which ordered pairs are a solution of the equation:

5x - 2y = 20

The ordered pairs are not given, so I will give a general answer, finding the general form of all the ordered pairs that are solutions.

We start with the equation:

5x - 2y = 20

First, we need to isolate one of the variables, let's isolate y.

2y = 5x - 20

y = (5/2)*x - 20/2

Then we get:

y = (5/2)*x - 10

From this, all the ordered pairs (x, y) that are solutions of this equation are given by:

(x, (5/2)*x - 10)

Then to get the points we just need to replace the "x" with numbers, for example for x = 0 we get the solution:

(0,  (5/2)*0 - 10) = (0, -10)

For x = 1 we get the solution:

(1, (5/2)*1 - 10) = (1, -15/2)

And so on.
