Answer:

$115

Step-by-step explanation:

Amount Harry had in the account = $450

He had $565 after the deposits.

We need to find the amount deposited by Harry.

Deposited amount = final amount-initial amount

= $565 - $450

= $115

So, each deposit is $115.

Answer:$57.50

Step-by-step explanation:

2x + 450 = 565

2x + 450 - 450 = 565 - 450

2x = 115

2x/2 = 115/2

x = 57.50

Answer:

13.50

Step-by-step explanation:

A Multiply 13.50 by 6 which equals $81.00

First of all, when we convert numbers to scientific notation, we should recall what scientific notation looks like.

A number in scientific notation looks like that:

____x10^-

____ is the coefficient (it should always be between 1 and 10)

- is the exponent.

1,000 in Scientific notation looks like so:

10x10^2

Now, the exponent doesn't mean that we multiply 10 times 10. It means we take 10 and move the decimal point 2 units to the right (the positive exponent indicates that we move the decimal point to the right)

98,000 in Scientific notation looks like so:

9.8x10^4

Step-by-step explanation:

Note: Consider we need to find the height of the container.

Given:

The volume of container in the shape of right rectangular prism = 43.875 cubic meters.

Length = 5 meters.

Width = 3.9 meters.

To find:

The height of the container.

Solution:

We know that the volume of a rectangular prism is:

[tex]V=l\times w\times h[/tex]

Where, l is length, w is width and h is height.

Putting [tex]V=43.875,l=5,w=3.9[/tex] in the above formula, we get

[tex]43.875=5\times 3.9\times h[/tex]

[tex]43.875=19.5\times h[/tex]

[tex]\dfrac{43.875}{19.5}=h[/tex]

[tex]2.25=h[/tex]

Therefore, the height of the rectangular container is 2.25 meters.

The sentence is:

In this problem:

[tex]\frac{x}{4}[/tex]

Kira expects that each person will pay at most $35, hence, the inequality is:

[tex]\frac{x}{4} \leq 35[/tex]

Solving the inequality, we have that:

Answer:

X=-5, y=1

Step-by-step explanation:

Add 3x+-3x to get 0. You are left with

-3y=12

4y=-11

add together

y=1

substitute1 in either equation to solve for x

-3x-3y=12

-3x-3(1)=12

-3x-3=12

-3x=15

x=-5

Answer:

Step-by-step explanation:

[tex]y - 15 = 20 \\ y - 15 + 15 = 20 + 15 \\ y = 20 + 15 \\ y = 35[/tex]

I hope that is useful for you :)

Easy. Just take -15 to the right hand side of the equation, which will give you, y = 20+15, implies y = 35.

Answer:

23w

Step-by-step explanation:

For 6days, She skates 3 * 6 = 18 miles

on weekend she skates 5 miles

Thus, In one week, she skates 23miles

In w week, she skates: 23w

in this exercise we have to know conversion, so it will be necessary to correct the space in time, which will represent in weeks:

28 weeks

So first, we have to calculate the total distance traveled in every day, like this:

[tex]days: 6*3=18\\weekends: 5*2=10\\total:18+10=28[/tex]

Answer:

[tex]\sin \theta = 0.153[/tex], [tex]\cos \theta = 0.988[/tex], [tex]\tan \theta = 0.155[/tex], [tex]\cot \theta = 6.462[/tex], [tex]\sec \theta = 1.012[/tex], [tex]\csc \theta = 6.538[/tex]

Step-by-step explanation:

Let be the point [tex](x,y)[/tex], the six trigonometric functions of the angle are represented by following formulas:

[tex]\sin \theta = \frac{y}{\sqrt{x^{2}+y^{2}}}[/tex] (1)

[tex]\cos \theta = \frac{x}{\sqrt{x^{2}+y^{2}}}[/tex] (2)

[tex]\tan \theta = \frac{\sin \theta}{\cos \theta} = \frac{y}{x}[/tex] (3)

[tex]\cot \theta = \frac{1}{\tan \theta} = \frac{x}{y}[/tex] (4)

[tex]\sec \theta = \frac{1}{\cos \theta} = \frac{\sqrt{x^{2}+y^{2}}}{x}[/tex] (5)

[tex]\csc \theta = \frac{1}{\sin \theta} = \frac{\sqrt{x^{2}+y^{2}}}{y}[/tex] (6)

If we know that [tex]x = 84[/tex] and [tex]y = 13[/tex], then the values of the six trigonometric functions is:

[tex]\sin \theta = \frac{y}{\sqrt{x^{2}+y^{2}}}[/tex]

[tex]\sin \theta = 0.153[/tex]

[tex]\cos \theta = \frac{x}{\sqrt{x^{2}+y^{2}}}[/tex]

[tex]\cos \theta = 0.988[/tex]

[tex]\tan \theta = \frac{y}{x}[/tex]

[tex]\tan \theta = 0.155[/tex]

[tex]\cot \theta = \frac{x}{y}[/tex]

[tex]\cot \theta = 6.462[/tex]

[tex]\sec \theta = \frac{\sqrt{x^{2}+y^{2}}}{x}[/tex]

[tex]\sec \theta = 1.012[/tex]

[tex]\csc \theta = \frac{\sqrt{x^{2}+y^{2}}}{y}[/tex]

[tex]\csc \theta = 6.538[/tex]

Answer:

A theater group has 7 boys and 19 girls. What is the ratio of girls to the entire group?

Step-by-step explanation:

One ratio problem would be:

A theater group has 7 boys and 19 girls. What is the ratio of girls to the entire group?

In order to solve this problem we would first need to calculate the total number of individuals in the theater group. We do this by adding the number of boys with the number of girls.

7 + 19 = 26

Now since we know there are 19 girls, the ratio would be 19 girls for every 26 individuals, or in ratio format it would be ...  19 : 26
