Answer:
f(x) = 10n
Step-by-step explanation:
If met with questions like these, the term "for each" means to multiply. simply write an equation that multiplies n and 10. Also "f(x)" can be substituted for "y" if that is what your instructor taught you.
please help, for a test, I need to know how you got the answer!

MIDSEGMENTS For problems 7-10, find the value of the variables. will give brainliest plzz
Answer: See explanation
Step-by-step explanation:
7.) 2 (x - 1) = 45
2x - 2 = 45
Add 2 to both sides
2x = 47
x = 23.5
8.) 5x - 2 = 2 (4)
5x - 2 = 8
Add 2 to both sides
5x = 10
Divide both sides by 5
x = 2
9.) x = 2 (30)
x = 60
10.) 3x - 6 = 2 (x)
3x - 6 = 2x
Add 6 to both sides
3x = 2x + 6
Subtract 2x from both sides
3x - 2x = 6
x = 6
2x + 1
Substitute x for 6
2 (6) + 1
12 + 1 = 13
2y = 13
Divide both sides by 2
y = 6.5

you can make a triangle in the corner with legs length s/2 and the angles are 45 degrees. in a 45 45 90 triangle, the legs are h/sqrt(2) where h is the hypotenuse. this means that s/2=9/2 sqrt(2), s=9 sqrt(2)
and s^2=162

Jack has written the name of each planet of the solar system on a separate piece of paper and has placed all these pieces of paper in a bag. The names he included are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. If he picks a piece of paper at random from the bag, what is the probability that the name of the planet written on it contains at least 6 letters?
Answer:
The probability that it would contain at least 6 letters is: 5/8
Step-by-step explanation:
From the question given above,
We know that there are 8 planet that was given.
Mercury 7 letters
Venus 5 letters
Earth 5 letters
Mars 4 letters
Jupiter 7 letters
Saturn 6 letters
Uranus 6 letters
Neptune. 7 letters
Therefore,
P(at least 6 letters) + P( Less than 6 letters) = 1
P (at least 6 letters) + P (3 planet) = 1
P (at least 6 letters) + ( 3/8) = 1
P(at least 6 letters) = 1 - (3/8)
= 5/8

The diagram compares the ratio of girls in the chorus to boys in the chorus. What is the ratio of girls to boys? If there are 50 students in the chorus, how many are girls, and how many are boys? ??50 The ratio of girls to boys is too. The number of girls in the chorus is. The number of boys in the chorus is.
Answer:
there are a total of 20 boys and 30 girls in the choir of 50 students
Step-by-step explanation:
Scale the ratio 2:3. so that the numbers on either side sum to 50 . 2+3=5 , and 50÷5=10 , so we scale our ratio by a factor of 10 . So there are a total of 20 boys and 30 girls in the choir of 50 students
Susan has 20 pieces of candy in a bag: 6 mint sticks, 11 jelly treats, and 3 fruit tart chews. If she eats one piece every 5 minutes, what is the probability her first two pieces will both be jelly treats?
Answer:
55%
Step-by-step explanation:
1. You add all the candy together to show that all the candies added together equals 20.
11+6+3=20
2. You divide 11 by 20 to get the decimal
11/20=.55
3. To get the percentage you just have to multiply .55 by 100.
4. The final answer should be 55 %

Steven bought a new computer at the end of a sale. The price of the computer was $52 on the day he bought it. The next day it had been marked up by 40%. What was the new price after the sale?
Answer:
$72.80
Step-by-step explanation:
You would multiply 52 with .40 to get 20.8. This is how much the price increased by. Then you would add the 20.8 to your original price of 52 to get 72.80.
(Also you use .40 initially because percent means out of 100. So 40% is the same as .4)
The new price after the sale of a new computer is, $72.8
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
The price of the computer was $52 on the day he bought it.
And, The next day it had been marked up by 40%.
Let the new price after the sale of a new computer = x
So, We can formulate;
⇒ x = $52 + 40% of $52
⇒ x = $52 + 40 × 52/100
⇒ x = $52 + $20.8
⇒ x = $72.8

The three statements that are true of a blackbody radiator are; A. It emits a range of wavelengths of EMR. C. It emits frequencies of EMR that depend on its temperature. D. It does not reflect much of the EMR it receives.
What is a blackbody radiator ?A blackbody radiator is an object which absorbs all the electromagnetic radiation at varying frequencies and angles of incidence.
Blackbody radiators posses a cavity which does not allow heat to escape from the radiator.
The electromagnetic spectrum is the distribution of radiation due to the different frequencies at which it radiates and its different intensities, that radiation is formed by electromagnetic waves, that are transverse waves formed by an electric field and a magnetic field perpendicular to it.
Therefore, we can conclude that the three statements that are true of a blackbody radiator are as listed.;
A. It emits a range of wavelengths of EMR.
C. It emits frequencies of EMR that depend on its temperature.
D. It does not reflect much of the EMR it receives.
Hence, the three statements that are true of a blackbody radiator are option A, C and D.

Find the slope of the line that contains the following points.
(4, 2) and (7, 7)
Graph by finding the intercepts
9x-15y = 45
Answer:
Look at picture
Step-by-step explanation:
X intercept is when y = 0. so...
9x -15*0 = 45
9x = 45
x = 5. so the coordinate is (5,0)
Y intercept is when x = 0. so...
9*0 - 15y = 45
y = -3. so the coordinate is (0,-3)
then you plot these 2 points and draw a line going across them

Patrick invested money into a special savers bank account each year money in the account earns 4% interest after one year, the total amount of money in the account was £291.20 how much did Patrick invest?
Answer: £280
Step-by-step explanation:
After a year, the total amount that was in the account was £291.20 which according to the question is 4% more than the amount Patrick invested.
Assume the amount invested is x.
x + 0.04x = 291.20
1.04x = 291.20
x = 291.20/1.04
= £280

Given:
[tex]\theta_1[/tex] is located in IV Quadrant.
[tex]\sin (\theta_1)=-\dfrac{24}{25}[/tex]
To find:
The value of [tex]\cos \theta_1[/tex].
Solution:
We have,
[tex]\sin (\theta_1)=-\dfrac{24}{25}[/tex]
We know that,
[tex]\sin^2 \theta+\cos^2\theta=1[/tex]
So,
[tex]\sin^2 (\theta_1)+\cos^2(\theta_1)=1[/tex]
[tex]\left(-\dfrac{24}{25}\right)^2+\cos^2(\theta_1)=1[/tex]
[tex]\cos^2(\theta_1)=1-\dfrac{576}{625}[/tex]
[tex]\cos^2(\theta_1)=\dfrac{625-576}{625}[/tex]
Taking square root on both sides, we get
[tex]\cos (\theta_1)=\pm \sqrt{\dfrac{49}{625}}[/tex]
[tex]\cos (\theta_1)=\pm \dfrac{7}{25}[/tex]
[tex]\theta_1[/tex] is located in IV Quadrant. In IV Quadrant the value of cos is positive. So,
[tex]\cos (\theta_1)=\dfrac{7}{25}[/tex]
Therefore, [tex]\cos (\theta_1)=\dfrac{7}{25}[/tex].
