Answer:
234
Step-by-step explanation:
So what we know is that
5x+9x= students
This equation is saying that for every 5 boys there are 9 girls
we can then plug in 364 for the number of students and add like terms
This means that 14x=364
this means that x=26
This means that there are 26 sets of 5 boys and 9 girls
this means that there are
130 boys
234 girls
The Tanners have received an $8000 gift from one of their parents to invest in their child’s college education. they estimate that they will need $20000 in 12 years to achieve their educational goals for their child. What interest rate compounded semiannually would the Tanners need to achieve this goal?
Answer:
3.4%
Step-by-step explanation:
For given problem:
P=8000
n=2*12=24 compounding perods
A=12000
A/P=(1+i)^24
12000/8000=(1+i)^24
1.5=(1+i)^24
take log of both sides
log1.5=24log(1+i)
log1.5/24=log(1+i)
.007337=log(1+i)
10^(.007337)=1+i
1+i=1.017
i=1.017-1=.017 (interest rate per compounding period)
annual interest rate=2*.017=.034 or 3.4%

Easiest way to calculate 22% mark up from a cost of say 39.99
Answer:
The markup amount on the cost 39.99 $ will be: 8.78 $
Step-by-step explanation:
Given
The cost = 39.99 (Let say in $)Mark up = 22%As
22% = 0.22
The markup of 22% on the cost can be calculated by multiplying the cost by 22% or 0.22
so
Markup amount = 0.22 × 39.99
= 8.78 $
Therefore, the markup amount on the cost 39.99 $ will be: 8.78 $

P varies directly as q. When q=31.2,p=20.8. Find p when q=15.3.
Answer:
a) p = 10.20
Step-by-step explanation:
Step(i):-
Given that p varies directly as q
p ∝ q
⇒ p = k q
where 'K' is proportionally constant
given p =20.8 and q = 31.2
p = k q
⇒ 20.8 = k (31.2)
[tex]k = \frac{20.8}{31.2}[/tex]
k = 0.666
Step(ii):-
p = k q
Given that q = 15.3 and k = 0.666
p = 0.666 ×15.3 = 10.20

Answer:
1 mi 1927 ft
Step-by-step explanation:
Turn everything into feet:
5mi x 5280 ft/1 mi = 26,400ft + 1,348 ft = 27, 748 ft
3mi x 5280 ft/1 mi = 15,840ft + 4,701 ft = 20,541 ft
Do the subtration that the problem wants you to do:
27, 748 ft - 20,541 ft = 7,207 ft
Turn the answer into mi & ft:
7,207 ft - 5280 ft = 1927 ft
=
1 mi 1927 ft

If the distance from point P to point L is the same as the distance from point P to point C, then P is on
Answer:
This answer is C, it is on the perpendicular bisector of segment LC.
Draw any line segment P and L, then another point C anywhere, but the length needs to be the same as PL. You will note that LC (if you connect those points) will become the perpendicular bisector to point P.

A brand of frozen green beans lists a weight of 32
ounces on its bag. Because of variability in the
manufacturing process, the bags often contain slightly
more, or less, than 32 ounces of green beans. An

beans and records their weights. The weights and their
relative frequencies are summarized in the histogram
below.
Which is true about the bags of green beans in the sample?
a- twenty percent of the bags have a weight below 32.2 ounces
b- sixty percent of the bags have a weight over 32.2 ounces

1. A school store sells pencils and erasers before school opens each day. On Monday, 13 pencils and
10 erasers were sold for $16.75. On Tuesday, 25 pencils and 2 erasen were sold for $19.85. What
is the price of a pencil? What is the price of an eraser.
Answer:
price of pencil is 0.74 and eraser is 0.72$
Step-by-step explanation:
Let, "p" represent pencils
and "e" represents erasers.
hence, according to question
13p+10e=16.75 ________(1)
and 25p+2e=19.85________(2)
Multiplying equation (2) by 5,
hence, 125p+10e=99.25________(3)
Substracting equation (3) and (1)
125p+10e-(13p+10e)=99.25-16.75
hence, 112p=82.5
p=0.74
substituting the value in equation (1),
13(0.74)+10e=16.75
9.57+10e=16.75
on solving,
e=0.72
hence, price of one pencil is 0.75$, and price of one eraser is $0.72
If 10% of a number is 36 and 55% of the same number is 198, find 45% of that number.
9514 1404 393
Answer:
162
Step-by-step explanation:
There are many ways to work this. Perhaps the simplest is to recognize that 45% of the number is the difference between 55% of it and 10% of it.
0.55n -0.10n = 0.45n
198 -36 = 0.45n = 162
45% of the number is 162.
_____
If you like, you can find the number as ...
0.10n = 36
n = 36/0.10 = 360
Then you can verify (if you like), that 55% of it is 198:
0.55(360) = 198 . . . . true
Finally, you can figure 45% of it:
0.45(360) = 162
__
Using proportions, you can determine the number to be ...
36/0.10 = n/0.45
n = 0.45(36/0.10) = 4.5(36) = 162
