Given:
The rate of interest on three accounts are 7%, 8%, 9%.
She has twice as much money invested at 8% as she does in 7%.
She has three times as much at 9% as she has at 7%.
Total interest for the year is $150.
To find:
Amount invested on each rate.
Solution:
Let x be the amount invested at 7%. Then,
The amount invested at 8% = 2x
The amount invested at 9% = 3x
Total interest for the year is $150.
[tex]x\times \dfrac{7}{100}+2x\times \dfrac{8}{100}+3x\times \dfrac{9}{100}=150[/tex]
Multiply both sides by 100.
[tex]7x+16x+27x=15000[/tex]
[tex]50x=15000[/tex]
Divide both sides by 50.
[tex]x=\dfrac{15000}{50}[/tex]
[tex]x=300[/tex]
The amount invested at 7% is [tex]300[/tex].
The amount invested at 8% is
[tex]2(300)=600[/tex]
The amount invested at 9% is
[tex]3(300)=900[/tex]
Therefore, the stockbroker invested $300 at 7%, $600 at 8%, and $900 at 9%.
the mean of 16,18,x,12 and 15 calculate the value of x
Answer:
29
Step-by-step explanation:
Mean = sum of datas/Sample size
Given the data 16,18,x,12 and 15
Sum = 16+18+x+12
Sum = 46+x
Mean = 15
Sample size = 5
Substitute
15 = 46+x/5
15 * 5 = 46+x
75 = 46 + x
x = 75-46
x = 29
Hence the value of x is 29

The total area of three walls, each 8' feet high; 14, long, and other is 10' long?
Answer:
304 feet²
Step-by-step explanation:
Given three walls :
First wall : 8 feets high ; 14 inches long
Second wall : 8 feets high ; 14 inches long
Third wall : 8 feets high ; 10 feets long
Area = Length * height
Area = (8 * 14) = 112 ft²
Area = (8 * 14) = 112 ft²
Area = (8 * 10) = 80 ft²
Total area :
(112 + 112 + 80) ft²
= 304 feet²
Find the area of each figure. Round to the nearest tenth if necessary
A scale model of an object has a scale of 1 cm : 2 ft. The actual object is 11 feet tall. How tall is the model?
Answer: The model is 69.420 feet tall.
Step-by-step explanation: I asked my teacher.
Answer:
5.5 cm
Step-by-step explanation:
If you take 11 and divide it by 2 you would get 5.5cm. This is the answer because If 1cm is 2 ft you divide it by the actual height and you end up with how tall the model would be.

Answer:
d = 50h
Step-by-step explanation:
We are using the linear property y = mx.
We know that distance = rate × time, so if we subsitute this, we get that the distance is d, the rate is 50 mph, and the time is h.
Therefore, we can form the equation d = 50h.
What is the area of the parallelogram?
Answer:
35
Step-by-step explanation:
The formula for solving the area of parrelelograms is B(base) times H(height).
the height here is 5 and the base is 7 so the area is 35.

a car travel 4hrs covers a distance of 480km how many hours does it take to cover a distance of 840km at the same constant speed
Answer:
7 hours
Step-by-step explanation:
4 hrs = 480km
1 hr = 480 ÷ 4 = 120km
840 ÷ 120 = 7 hours
A market research analyst claims that 32% of the people who visit the mall actually make a purchase. You think that less than 32% buy something and decide to test the claim. You stand by the exit door of the mall starting at noon and ask 82 people as they are leaving whether they bought anything. You find that only 20 people made a purchase. The value of the test statistic is about:
A. 1.74
B. 1.60
C. 1.48
D. -1.60
E. -1.48
Answer:
E. -1.48
Step-by-step explanation:
The test statistic is:
[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the expected value, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
A market research analyst claims that 32% of the people who visit the mall actually make a purchase.
This means that:
[tex]\mu = 0.32[/tex]
[tex]\sigma = \sqrt{0.32*0.68} = 0.4665[/tex]
You stand by the exit door of the mall starting at noon and ask 82 people as they are leaving whether they bought anything. You find that only 20 people made a purchase.
This means that [tex]n = 82, X = \frac{20}{82} = 0.2439[/tex]
The value of the test statistic is about:
[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]t = \frac{0.2439 - 0.32}{\frac{0.4665}{\sqrt{82}}}[/tex]
[tex]t = -1.48[/tex]
So the correct answer is given by option E.
A.3(f) The line graphed on the grid represents the first of two equations in a system of linear equations.

i need help finding the surface area of a right triangular prism.
Answer:
Surface area of the right triangular prism = 180 m²
Step-by-step explanation:
Surface area of the given right triangular prism = Surface area of triangular sides + Surface area of the rectangular surfaces
Surface area of the triangular sides = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(AB)(AC)[/tex]
By applying Pythagoras theorem in ΔABC,
BC² = AB² + AC²
(13)² = 5² + (AC)²
AC² = 169 - 25
AC = 12 m
Therefore, area of the triangular sides = [tex]\frac{1}{2}(5)(12)[/tex] = 30 m²
Area of the rectangular side with dimensions 5m × 4m,
= 5 × 4
= 20 m²
Area of the rectangular side with dimensions 13m × 4m
= 13 × 4
= 52 m²
Area of the rectangular side with dimensions 12m × 4m
= 12 × 4
= 48 m²
Total surface area of the prism = 2(30) + 20 + 52 + 48
= 180 m²
