Answer:
400ml of juice
Step-by-step explanation:
1 litre of water = 100ml of juice
4 litres of water =? ml of juice
to get from 1 litre to 4 litre of water you multiply by 4,so you do the same for the juice and multiply the juice by 4.
100×4=400
4 litres of water = 400ml of juice

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:
Suppose 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]
Multiplying both sides by 100, we get
[tex]7x+16x+27x=15000[/tex]
[tex]50x=15000[/tex]
Dividing both sides by 50, we get
[tex]x=\dfrac{15000}{50}[/tex]
[tex]x=300[/tex]
So, 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]
Hence, the stockbroker invested $300 at 7%, $600 at 8%, and $900 at 9%.
if x degree + x + 10 degree + x + 15 degree + x + 20 degree + x + 25 degree + x + 30 degree
Answer:
x° + x° + 10° + x° + 15° + x° + 20° + x° + 25° + x° + 30°
= 6x° + (10 + 15 + 20 + 25 + 30)°
= 6x° + 100
0 = 6x + 100
6x = 100
X = 100/6
X = 16.66

what is the area of the shaded region in the figure below
Answer:
4 cm^2
Step-by-step explanation:
2 x 2 x 0.5 x 2 = 4 cm^2
Hi there!
[tex]\huge\boxed{4 \text{ cm}^{2}}[/tex]
Find the area of the shaded area using the given dimensions:
The shaded area is divided up into two triangles, each with a base of 2 cm and a height of 2 cm. Use the following equation to solve for area:
A = 1/2(bh)
A = 1/2(2 · 2)
A = 1/2(4) = 2 cm²
There are two triangles, therefore:
2 × 2 = 4 cm²
A hair dryer wastes 376J for every 1500J of electrical energy it uses. How efficient is the hairdryer?
Answer:
[tex] \boxed{efficiency, \gamma = 74.93 \%}[/tex]
Step-by-step explanation:
[tex] efficiency, \: \gamma = \frac{1500 - 376}{1500} \times 100 \\ \gamma = \frac{1124}{1500} \times 100 = 74.93 \\
efficiency, \gamma = 74.93 \%[/tex]
You put $500 in a savings account. The account earns $20 simple interest in 6 months. What is the annual interest rate? Write your answer as a percent
Answer:
8%
Step-by-step explanation:
For simple interest, we use the equation I = PRT, where I is the interest earned, P is the principal/amount invested, R is the rate as a decimal, not percentage, and T is the time in years.
For this problem, we have to use 0.5 for T, because 6 months is 1/2 a year.
20 = (500)(r)(0.5)
20 = 250r
r = 0.08 = 8%
For f (x) = 2x+1 and g(x) = x2 - 7, find (fºg)(2).
Answer:
Step-by-step explanation:
Your first step will be to set up the problem:
f(x) - g(x)
Next you will substitute in your values:
(2x + 1) - (x2 - 7)
The easiest way to do the subtraction problems is to distribute your negative into your second set of parenthesis, so your expression would become:
2x + 1 - x2 + 7
Then combine your like terms:
2x - x2 + 8
Lastly put your expression in standard form (highest exponent to lowest)
-x2 + 2x + 8

what is the density of the oak board? it is 5.5 inches wide, 1.5 inches thick and 3 feet long
multiply 5.5 the width with 1.5 by 3 which gives you 24.75 inches feet long.
5.5 x 1.5 x 3=24.75 that's your answer.
Answer:297 cubic inches, other person is incorrect.
Step-by-step explanation:5.5 inches* 1.5inches * 3 feet
Convert 3 feet to inches and you have 36 inches. So now it becomes 5.5inches*1.5inches*36inches = 297 cubic inches

Answer:
x = 45
Step-by-step explanation:
x + 2x + x = 180
4x = 180
x = 45
Answer:
Since its a triangle, all the angles must add to 180. So x+x+2x=180. Solve for x and you got your answer.

In the last year, U.S. car sales of all makes and models have dropped by 16%. Let's say that a car dealer sells 325 cars. If this number drops by 16%, how many cars will the dealer sell then? Round to the nearest whole number.
A 203 cars
B 309 cars
C 273 cars
D 256 cars
Answer:
c. 273 cars
Step-by-step explanation:
First you need to find what 16% of 325 is
325x.16=52
because the number sold dropped by 16% you will subtract 52 from 325
325-52=273
you can also calculate the answer by subtracting 100% by 16%
100%-16%=84%
now you can calculate 84% of 325
325x.84=273
