Enoch is 30Martin is 15Step-by-step explanation:
The difference in ages remains the same over time. Enoch, at twice Martin's age, is still 15 years older. That means Martin is 15 and Enoch is 30.
Convert these numbers into Scientific Notation
Answer:
1000=1×10^3
98000=9.8×10^4
[tex]\huge\boxed{\boxed{\textbf{Hi\:there!}}}}[/tex]
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

What operation would you use to solve the equation below for y? y - 15 = 20
Answer:
y = 35Step-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.
Question: Write a word problem that involves ratios. Discuss how you would go about solving this problem.
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

Help me
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

Carla roller skates 3 miles each weekday and 5 miles each day on the weekend.Which expression represents how many miles she roller skates in w weeks?
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]

Find the values of the six trigonometric functions of an angle in standard position if the point with coordinates (84, 13) lies on its terminal side.
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]

Jesse has a storage container in the shape of a right rectangular prism. The volume of the container is 43.875 cubic meters, the length is 5 meters and the width is 3.9 meters.
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.

Kira and her friends are planning to take a trip next summer to drive to Big Bend National Park. They plan to split the cost of gas equally among the 4 of them. Kira expects that each person will pay at most $35.
Let x represent how much Kira expects the gas to cost in all. Which inequality describes the problem?
Using proportions, it is found that the inequality that describes the problem is:
[tex]\frac{x}{4} \leq 35[/tex]
The sentence is:
Kira expects the gas to cost at most $140.What is a proportion?A proportion is a fraction of total amount.In this problem:
The total amount is the gas cost, which is of x.This amount will be evenly split among four people, hence the amount paid by each person is given by:[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:
[tex]x \leq 140[/tex]
Hence, the sentence is:
Kira expects the gas to cost at most $140.You can learn more about proportions at https://brainly.com/question/24372153
6. Harry deposited an equal amount into his savings account on two occasions. If he already had $450 in the account and had $565 after the deposits, how much was each deposit?
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
