Justin has $0.90 worth of nickels and dimes. He has a total of 15 nickels and dimes altogether. Determine the number of nickels, x,x, and the number of dimes, y,y, that Justin has.

Answer:

EF = 12

arc AG = 62°

Step-by-step explanation:

since ED = 13, EC = 13, so DF = 10/2 = 5

EF² + 13² - 5² = 169 - 25 = 144

EF = √144 = 12

∠AEG = 90° - 28° = 62°

arc AG = 62°

Step-by-step explanation:

Expand the brackets. 7 ( 5 + g ) 11 ( 3s – 4 ) 4 ( 4 – x ) 8 ( 6 + 4w )

We will expand each of the bracket using distributive property

For the expression 7(5+g)

7(5)+7g

= 35+7g

For the expression 11(3s-4)

= 11(3s)-11(4)

= 33s-44

For the expression 4(4-x)

= 4(4)-4x

= 16-4x

For the expression 8(6+4w)

= 8(6)+8(4w)

= 48+32w

Step-by-step explanation:

Answer:

33 square units

Step-by-step explanation:

Assuming that each line on this grid increases by a value of one, the area of the polygon can be determined by breaking it down into a large rectangle and two smaller triangles.

The area of a rectangle is simply [tex]A = bh[/tex], where b represents the base and h represents the height.

Counting the size of each side, we can determine that they are 6 units for the base and 4 units for the height.

Substituting in the values, we get:

[tex]A = (6)(4)\\A = 24[/tex]

The area of the rectangle is 24 square units

The area of a triangle is simply [tex]A = \frac{1}{2} bh[/tex].

The base of each triangle is 3, and the height of each triangle is also 3.

Substituting in the values, we get:

[tex]A = \frac{1}{2} (3)(3)\\A = \frac{1}{2} (9)\\A = 9 / 2\\A = 4.5[/tex]

The area of each triangle is 4.5 square units

To get the area of the polygon, we simply add up the area of the rectangle and both triangles

[tex]A = 24 + 4.5 + 4.5\\A = 24 + 9\\A = 33[/tex]

The total area of the polygon is 33 square units.

Answer:

C) 16.97

Step-by-step explanation:

If the sides are 12, the hypotenuse is 12*(2^1/2) to the 45 - 45 - 90.

When you put 2*(2^1/2) into the calculator, you get 16.97.

Answer:

16.97

Step-by-step explanation:

Equation used:  c=[tex]\sqrt{ax^{2} +bx^{2} }[/tex]

Equation filled out: c=[tex]\sqrt{12x^{2} +12x^{2} }[/tex]

Next step:  c=[tex]\sqrt{288}[/tex]

Total: 16.97056 though to the hundreath place 16.97

So if both legs are 12 inches each, that mean that 12^2 +12^2  which totals out too 288, then you find the full square of 288 which leads out to 16.97!

Answer:

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

We know that ∠ 1 + ∠ 2 + ∠3 = 180 → (1)

and ∠ 3 + ∠ 4 = 180 → (2)

From (2) ∠ 3 = 180 - ∠ 4

Substitute ∠ 3 = 180 - ∠ 4 into (1)

∠ 1 + ∠ 2 + 180 - ∠ 4 = 180 ( add ∠ 4 to both sides )

∠ 1 + ∠ 2 + 180 = 180 + ∠ 4 ( subtract 180 from both sides )

∠ 1 + ∠ 2 = ∠ 4 → C

A wading pool is being filled with water from a garden hose at a rate of

6 gallons per minute. If the pool already contains 80 gallons of water and can hold 152 gallons, and it will take 12 minutes for the pool to overflow.

In this scenario, we have a wading pool being filled with water from a garden hose at a constant rate of 6 gallons per minute. The pool already contains 80 gallons of water, and its maximum capacity is 152 gallons. We want to find out how long it will take for the pool to overflow.

Let's use "t" as the variable representing time in minutes. After "t" minutes, the amount of water in the pool will be the initial 80 gallons plus the additional water being filled by the hose at a rate of 6 gallons per minute. We can express this mathematically as:

Amount of water in the pool after "t" minutes = 80 gallons + 6 gallons/minute * "t" minutes

Now, we want to find out when the pool will overflow. The pool's capacity is 152 gallons, so we set up an equation to represent this:

Amount of water in the pool after "t" minutes = 152 gallons

Substituting the earlier expression for the amount of water in the pool after "t" minutes:

80 gallons + 6 gallons/minute * "t" minutes = 152 gallons

Now, we have an equation to model the scenario: "80 + 6t = 152".

To find the time "t" it takes for the pool to overflow, we need to solve this equation for "t."

To solve for "t," we need to find the value of "t" that satisfies the equation we derived earlier:

80 + 6t = 152

To isolate "t," we'll perform the following steps:

Subtract 80 from both sides to move the constant term to one side of the equation.

80 + 6t - 80 = 152 - 80

This simplifies to:

6t = 72

Divide both sides by 6 to solve for "t."

t = 72 / 6

t = 12

So, it will take 12 minutes for the pool to overflow.

In summary, we have a wading pool being filled with water at a rate of 6 gallons per minute, and we want to know when it will overflow, given its current water level of 80 gallons and a maximum capacity of 152 gallons. The equation "80 + 6t = 152" models this situation, with "t" representing the time in minutes. Solving this equation will give us the time it takes for the pool to overflow.

Answer:

The full mass is 500 kg.

Step-by-step explanation:

Let's break this down.

4% of the mass is 20 kg.

4% = 4/100 or 0.04

"of" = multiply

mass = our unknown value, x

is = equal sign

20 kg = our end result

Let's make an equation out of this.

4% of the mass is 20 kg.

0.04 • x = 20

Divide both sides by 0.04.

x = 500

The full mass is 500 kg.

Hope this helps!

Answer:

500 kg

Step-by-step explanation:

4% = 20 kg

→ Find 1% by dividing both sides by 4

1% = 5 kg

→ Find 100% by multiplying both sides by 100

100% = 500 kg

Given:

Ricky made approximately 4 goal points for every 7 of his shots on goal.

To find:

The probability that Ricky would make 2 goal points on two shots in a row during the season.

Solution:

Using the given information, the probability of a goal point on one shot is:

[tex]P(one\ goal)=\dfrac{4}{7}[/tex]

We need to find the probability that Ricky would make 2 goal points on two shots in a row during the season.

Since the both shots are independent events therefore,

[tex]P(Two\ goals)=P(one\ goal)\times P(one\ goal)[/tex]

[tex]P(Two\ goals)=\dfrac{4}{7}\times \dfrac{4}{7}[/tex]

[tex]P(Two\ goals)=\dfrac{16}{49}[/tex]

Therefore, the required probability is [tex]\dfrac{16}{49}[/tex].

Answer:

its c ! just took the test :)

Option C is correct. The equation that matches the function shown in the graph is expressed as y = 3sin(x-π)

The general formula for a sine function is expressed as;

y = Asin(x+Ф)

A is the amplitude i.e the maximum point on the curve. From the diagram, we can see that the maximum point is at 3 (factor 3 elongates the curve).

A = 3

Also, since the graph translates to the right by π, hence Ф = -π

Substituting the resulting values into the formula, we will have;

y =3sin(x+ (-π))

y = 3sin(x-π)

Hence the equation that matches the function shown in the graph is expressed as y = 3sin(x-π)
