Answer:
18 students
Step-by-step explanation:
Now think of it in this form. 12 students wanna learn french which is 24% and in this problem we have to find 24% of "x" is 12. The answer is obviously 50. Now go to German and you can see that 18% want to learn German. All you have to do is find 50% of 18 to get your answer which is 9. Now follow that same pattern with the Spanish one. If 36% want to learn Spanish, just find 50% of it or half of it and that could be done by doing 36 divided by 2 to get 18 as your answer. Another way to do it is my turning 50% into 0.5 and multiplying it by 36 to get your answer. As a result, your answer is 18 students want to learn Spanish.

the sum of third and seventh terms of an AP is 20 . Find the sum of the first nine
Given:
The sum of third and seventh terms of an AP is 20.
To find:
The sum of the first nine terms.
Solution:
We have, the sum of third and seventh terms of an AP is 20.
[tex]a_3+a_7=20[/tex] ...(i)
nth term of an AP is
[tex]a_n=a+(n-1)d[/tex]
where, a is first term and d is common difference.
[tex]a_3=a+(3-1)d[/tex]
[tex]a_3=a+2d[/tex] ...(ii)
[tex]a_7=a+(7-1)d[/tex]
[tex]a_7=a+6d[/tex] ...(iii)
Using (i), (ii) and (iii), we get
[tex](a+2d)+(a+6d)=20[/tex]
[tex]2a+8d=20[/tex] ...(iv)
Now, the sum of first n terms of an AP is
[tex]S_n=\dfrac{n}{2}[2a+(n-1)d][/tex]
Put n=9 to find the sum of first 9 terms of an AP.
[tex]S_n=\dfrac{9}{2}[2a+(9-1)d][/tex]
[tex]S_n=\dfrac{9}{2}[2a+8d][/tex]
[tex]S_n=\dfrac{9}{2}[20][/tex] [Using (iv)]
[tex]S_n=\dfrac{180}{2}[/tex]
[tex]S_n=90[/tex]
Therefore, the sum of the first 9 terms is 90.
You mix 1/ 3cup of blue paint for every 2/ 3cup of yellow paint to make green paint. You use 4 cups of yellow paint. How much blue paint do you use?
Answer:
You will use 2 cups of blue paint for 4 cups of yellow paint.
Step-by-step explanation:
Given that:
There is 1/3 cup of blue paint for every 2/3 cup of yellow paint
We will find unit rate in terms of yellow paint.
2/3 cups of yellow paint = 1/3 cup of blue paint
Multiplying both sides by 3/2
[tex]\frac{2}{3}*\frac{3}{2}=\frac{1}{3}*\frac{3}{2}\\1\ cup\ of\ yellow\ paint = \frac{1}{2}\ cup\ of\ blue\ paint[/tex]
Now,
4 cups of yellow paint = [tex]4*\frac{1}{2}[/tex] cups of blue paint
4 cups of yellow paint = 2 cups of blue paint
Hence,
You will use 2 cups of blue paint for 4 cups of yellow paint.

-. The 7th grade enrollment went from 400 to 300 students last year. What was the percent of
decrease?
=========================================
Work Shown:
A = old value = 400
B = new value = 300
C = percent change
C = [(B-A)/A]*100%
C = [(300-400)/400]*100%
C = (-100/400)*100%
C = (-0.25)*100%
C = -25%
The negative value of C means we have a percent decrease. Specifically we have a 25% decrease.
---------
We can see that by saying:
25% of 400 = 0.25*400 = 100
400 - (25% of 400) = 400 - 100 = 300

Carol took a math test and answered 16 of the 20 questions correctly. What was Carol's percentage score on the test.
Answer:
80%
Step-by-step explanation:
Calculation for what was Carol's percentage score on the test
Using this formula
Percentage score on the test=Answered questions/Numbers of questions *100
Let plug in the formula
Percentage score on the test=16/20*100
Percentage score on the test=0.80*100
Percentage score on the test=80%
Therefore Carol's percentage score on the test will be 80%
Can two angles be both complementary and vertical? If so, can you determine the angles? Explain how you know.
Answer:
Complementary angles are those that sum up to 90o.Vertical angles have equal measures. Therefore, if vertical angles measure 45o each, they are complementary.
Explanation: Here how it might look if angles ∠1 and ∠3 are measured at 45o.

Solve the proportion (w+12)/(3w+5)=3/4
Answer:
[tex]w=6.6[/tex]
[tex]18.6:24.8::3:4[/tex]
Step-by-step explanation:
[tex]As\ we\ know\ that,\\(w+12):(3w+5)::3:4\\By\ the\ proportion\ method\ of\ multiplying\ the\ means\ and\ the\ extremes,\\we\ get,\\(w+12)*4=3*(3w+5)\\4w+48=9w+15\\48-15=9w-4w\\33=5w\\[/tex]
[tex]w=33/5\\w=6.6[/tex]
[tex]By\ substituting\ the\ value\ of\ w\ in\ the\ proportion. you\ get:\\(6.6+12)/(3*6.6+5)=3/4\\18.6/24.8=3/4\\18.6:24.8::3:4[/tex]

What value of b will cause 16x ^ 2 + bx + 4 = 0 to have one real solution ?
Answer:
b = 16
Step-by-step explanation:
16*x + b*x + 4 = 0
Solving for x we get:
x₁,₂ = - b ± √ b² - 4*a*c ] / 2*a (1)
If we take a look to the square root
√ b² - 4*4*16 = √ b² - 256
if we make √ b² - 256 = 0
b² = 256 ⇒ b = 16
Then equation (1) becomes:
x₁,₂ = ( - 16 ± 0 ) / 32
x = - 1/2

Sheryl has a Christmas lighting project. She is going
to put lights around the outside of 15 windows with
a height of 4ft and a width of 2ft. She also wants to
put lights around her 3 garage doors that are 9 feet
tall and 9 feet wide. How many feet of christmas
lights would be needed for this project?
And 288ft says it’s incorrect
Answer:
If hanging Christmas lights around the garage door is on your holiday to do list, make sure to do it right. Decorating shouldn't be a once-a-year activity that does permanent damage to your home or your body.
When it comes to hanging holiday lights around your garage door, use clips and hooks specifically designed for the task. Avoid using metal fasteners like staples or nails if you are attaching lights directly to the trim; the metal can damage the wiring and create a fire or electrocution hazard. Instead, clip the plastic fasteners to the light string and attach the plastic fasteners to your trim. This way the clips can remain throughout the year, and lights are more easy to hang in the holidays to come.
For the vertical runs, find the trim clips that wrap around the light string and hold it into place (this is particularly important for our Sioux City and Yankton breezes and blizzards). Aim for a clip every 12 inches or so. Some homeowners choose to nail the clips for stability; others use a removable adhesive.
If you are continuing to light up your house with lights around your roof and gutter lines, there are other items that can help make this process easier. Roof and gutter clips can be pressed directly onto the home's exterior; they typically have a hook at the bottom that grabs the light string. Please be very careful when working on high and precarious locations!
