The space club is printing posters for an upcoming competition. The
printer charges $200 plus $2 for every poster. How many posters can be
printed for $950?
Answer:
375 posters can be printed for $950
Step-by-step explanation:
First, create an equation. X = number of posters: 200+2x=950
Second, subtract 200 from both sides to get an equation of: 2x=750
Third, divide 2 on both sides to get: x = 375
Given: cosθ= 4/5
Find: sin2θ
Answer:
cos theta=4/5
b/h=4/5
b=4 and h=5
p=?
H^2=P^2+B^2
5^2=P^2+4^2
25-16=P^2

3=P
Now,
sin2theta

=9/5
Step-by-step explanation:
Answer:
About 36.87 degrees; sinθ=3/5
Step-by-step explanation:
Note: I made an assumption with the Find: sin2θ part of your question, as it turned up as invalid when working on it on my end. Therefore, I assumed that it was sinθ. If it was something else, tell me and I can correct the answer/content.
Since within a triangle there are three sides when solving an angle, being opposite, adjacent and hypotenuse.
By already having cosθ=4/5. the rest of the problem can be solved. Since cosine is adjacent over hypotenuse, we can use the Pythagorean Theorem, solving for one of the legs of the triangle with:
c^2-b^2=a^2
Now, just plug in c as the 5 (the hypotenuse) and b as 4 (one of the legs).
5^2-4^2=a^2
25-16=a^2
9=a^2
a=3
The other leg is 3. With this, 3 would be the opposite angle from sin 20. Therefore, it can be plugged in the sine equation to get the answer. Remember, sine is Opposite/Hypotenuse.
sinθ=3/5
Move over the sine to then opposite side, inverse it:
θ=sin-1 3/5
Use a calculator.
θ = about 36.87 degrees.

What is the area of the triangle?
A. 35 cm
B. 35 cm2
C. 17.5 cm2
D. 17.5 cm
Answer:
C
Step-by-step explanation:
Area of the triangle is cm^2 which makes A and D not true.
Formula
Area = 1/2 * b * h
b = 7
h = 5
Area = 1/2 * 7 * 5
Area = 1/2 35
Area = 17.5 cm^2
How many mL (milleters) are in 12.9 liters?
1. 129 mL
2. 1,290 mL
3. 12,900 mL
4. 129,000 mL
please help ASAP!
Given statement solution is :-12.9 liters are in milleters is 12,900 mL.
The metric system uses millilitres as the unit of volume, denoted by the letters ml or mL. One cubic centimetre, or one thousandth of a litre, is equivalent to one millilitre. That's a little sum in the imperial system.
A measure of volume in the metric system. One thousand milliliters equal one liter. Additionally known as cc, mL, and cubic centimetre.
To convert liters to milliliters, you need to multiply the number of liters by 1,000, since there are 1,000 milliliters in a liter.
So, multiplying 12.9 by 1,000 will give you the answer to how many millilitres are in 12.9 litres:
12.9 litres x litres per 1,000 = 12,900 mL
Therefore, option 3: 12,900 mL, is the milleters right response.

1. The amount of time Mr. Smith spends exercising each day is
approximately normally distributed with a mean of 30 minutes and a
standard deviation of 10 minutes. On approximately what percent of the
days in a year does Mr. Smith exercise for between 10 minutes and 40
minutes?
Answer:boy
Step-by-step explanation:boy
Mr. Smith exercises for between 10 and 40 minutes on 77.45 percent of the days in a year.
Given that his exercising time follows a normal distribution with a mean of 30 minutes and a standard deviation of 10 minutes.
Here we have to find the percentage of days in a year that Mr. Smith exercises for between 10 and 40 minutes,
First, we need to standardize the values of 10 and 40 minutes using the formula,
⇒ z = (x - μ) / σ
where x is the value we want to standardize,
μ is the mean,
And σ is the standard deviation.
For x = 10:
⇒ z = (10 - 30) / 10
= -2
For x = 40:
⇒ z = (40 - 30) / 10
= 1
Now, we need to find the probability of Mr. Smith exercising between -2 and 1 standard deviations from the mean.
We can use a standard normal distribution table or a calculator to find this probability.
Using a standard normal distribution table,
we can find the probability of z being between -2 and 1 is about 0.7745. This means that on approximately 77.45% of the days in a year, Mr. Smith exercises for between 10 and 40 minutes.
Therefore,
Mr. Smith exercises for between 10 and 40 minutes on approximately 77.45% of the days in a year.

Write a paragraph (4-5 sentences) explaining how we can help or change racism to black people
No copying from internet please
Answer
A few ways we could stop racism against black people in this country is to stop the perpepuation of black stereotypes in media. Such as the loud, aggressive black man, or the rude, catty black woman. It causes a harmful view on black people and can result in racial profiling. Another way to combat this racism is to fight off systemic racism. Black people who have unique names, usually African names, are more likely to get turned down for a job when they turn in their resume to an establishment. This is because they automatically assume that they'll be trouble, and won't be a good worker.

Step-by-step explanation:
5 1/ 2 +2 1/ 7
= 11/ 2 +2 1/ 7
= 11/ 2 + 15/ 7

=7 9/ 14
Answer:
7 9/14
Step-by-step explanation:
Combine the whole numbers and fractions together:
(5 + 2) + ( 1/2 + 1/7)
The whole numbers part is:
5 + 2 = 7
For the fractions part:
The Least Common Multiple (LCM) of 2 and 7 is 14. Multiply the numerator and denominator of each fraction by whatever value will result in the denominator of each fraction being equal to the LCM:
1/2 + 1/7 = 1 × 7 + 1 × 2

Kevin and Doreen each made a fruit salad. The amounts of ingredients they have are shown. Kevin used all of the strawberries, blueberries, and melon to make his fruit salad. Doreen made 2 cups of fruit salad containing all of the bananas, peaches and apples. How much fruit salad did Kevin make? How much more fruit salad did Doreen make than Kevin?
Answer:
The first thing you should do for this case is to graph the data you have in the statement to see the relationship between grapes and blueberries.
The function represented by the table is
y = 0.25x
Then, as Mandie is making 15 glasses of fruit salad, we have:
y + x = 15
We have two equations and two unknowns that we must solve.
y = 0.25x
y + x = 15
Resolving
For x:
0.25x + x = 15
1.25x = 15
x = 15 / 1.25 = 12
For y:
y = 0.25x = 0.25 (12) = 3
Answer
The ratio of grapes to blueberries she should use is 12: 3

Answer:
y = x + 2
Step-by-step explanation:
We observe that the line crosses the y-axis at y=2, so the y-intercept is 2.
The line has a rise of 1 grid square for each run of 1 grid square to the right. The slope is the ratio of rise to run:
m = rise/run = 1/1 = 1
The slope and intercept can be put into the slope-intercept form:
y = mx + b . . . . . line with slope m and y-intercept b
y = 1x +2 . . . . . . line with slope 1 and y-intercept 2

Step-by-step explanation:
Sally and Suzie both agree that m∠A + m∠B = 180⁰.
Sally claims ∠A and ∠B are supplementary.
Suzie claims ∠A and ∠B are not supplementary because they are not adjacent.
Who is correct?
Explanation:
The angles do not need to be touching, or adjacent, for them to be supplementary. They simply need to add to 180 degrees.
We have 70+110 = 180, so that proves the angles are supplementary. They can be rearranged to glue together to form a straight angle.
If the angles were supplementary and adjacent, then we can consider them as a linear pair. This is possibly what Suzie might be thinking about.
