Kinyua spent 1/4 of his net salary on school fees. He spent 1/4 of the remainder on electricity and water bills. He spent 1/9 of what remained on transport. If he finally has she. 8400 calculate his total salary
Answer:
Let his net salary = x.
He spent 1/4th of x on School fees
Remainder = 1-1/4 = 3x/4
He spent 1/4th THE REMAINDER on Electricity and Water Bils
1/4 of remainder (3x/4) = 1/4 x 3x/4 = 3x/16
He spent 3x/16 of this salary on Electricity and Water Bills... We should subtract this to know our current value or cash at hand
New Remainder = 3x/4 - 3x/16
= 9x/16.
He spent 1/9th OF WHAT REMAINED ON TRANSPORT.
1/9 x 9x/16
=x/16
New Remainder
= 9x/16 - x/16
=x/2.
If he finally had 8,400
Then
x/2=8,400
x=2x8,400
x= 16,800.
This answer is Correct. You can check it by using our x as 16,800 and solve from the start... You'll arrive at 8400 as your remainder. Have a great day!!!

Answer:
1. 23
2. 8
Step-by-step explanation:
1. 180-157 = 23
2. 15²+x²=(9+x)²
225 +x²=81+18x +x²
225-81=18x
144 = 18x
x = 144/18 = 8

Hi there!

I believe your answer is:
[tex]y^\frac{2}{3}[/tex]

Here’s why:
We are supposed to rewrite a radical expression as an expression with fraction exponents.⸻⸻⸻⸻
The rule for a fraction exponent is:
[tex]a^{\frac{x}{y}}=\sqrt[y]{a^x}\\\\\\\huge\boxed{\frac{\text{Power}}{\text{Root}}}[/tex]
⸻⸻⸻⸻
We are given the expression of [tex]\sqrt[3]{y^2}[/tex].
⸻⸻⸻⸻
[tex]\boxed{\text{Rewriting the expression:}}\\\\\sqrt[3]{y^2}\\\\\text{The '3' is the root and the '2' is the power.}\\\\\rightarrow \sqrt[3]{y^2} \\\\\rightarrow {y^{\frac{2}{3}}[/tex]

Basado en un tiempo de 12 horas, podría escribirse tiene: 3: 40 pm
Usando el formato de reloj de 24 horas; donde 3 pm es equivalente a 15; por lo tanto, podría escribirse como: 15:40
Además, el tiempo se puede informar en palabras de la siguiente manera:
20 minutos antes de las 4 pm

While reading a book, Shara
estimates that she is 75%
finished. If she has read 216
pages, then how long is the
book?
Answer:
288 pages
Step-by-step explanation:
Step 1: Set up a fraction (Since 75% is 216, 100% is x. We don't need the percent (%).)
[tex]\frac{216}{75} = \frac{x}{100}\\\\[/tex]
Step 2: Solve; Divide the given values (All we are doing is finding what is between those values.)
[tex]\frac{216}{75}\\\\216 \div 75\\\\= 2.88[/tex]
Step 3: Multiply the result to the value (Now we multiply the result to 100 because that would make it equal.)
[tex]100\\\\2.88 \times 100\\\\= 288[/tex]
Therefore, the book is 288 pages long.

Answer:
116
Step-by-step explanation:
a line is 180 degrees so subtract 64 and you get 116, that is your angle
Given: these two lines are parrallel cut by a transversal, 4 is 64 degrees
because 4 is given we know 6 is also 64 becasue they are alternative interior angles
all straight lines measure to 180 degrees so 3 and 5 become 116 because 180-64=116 (we also know these lines are parallel becasue 4 and 5 are supplementary, they add up to 180 as well.)
becasue 5 is 116 8 needs to be 64 and becasue 8 is 64 to equal 180 7 needs to be 116 (again, they need to add up to 180 becasue they are a straight line)

ABC maps the outline of a new park. What is the area of the park?
the multiple choice answers are in the photo
Answer:
[tex]Area = 10[/tex]
Step-by-step explanation:
Given
[tex]A = (2,1)[/tex]
[tex]B =(4,7)[/tex]
[tex]C =(6,3)[/tex]
Required
The area of the park
The outline is a triangle and as such, the area is calculated using:
[tex]Area = \frac{1}{2}|(x_1y_2 - x_2y_1) + (x_2y_3 - x_3y_2) + (x_3y_1 - x_1y_3)|[/tex]
This gives:
[tex]Area = \frac{1}{2}|(2*7 - 4*1) + (4*3 - 6*7) + (6*1 - 2*3)|[/tex]
Using a calculator, we have:
[tex]Area = \frac{1}{2}|-20|[/tex]
Remove absolute bracket
[tex]Area = \frac{1}{2}*20[/tex]
[tex]Area = 10[/tex]

y is inversely proportional to x.
When =9, y = 8.
Find y when x= 6.
Answer:
y=12
Step-by-step explanation:
y is inversely proportional to x
y=k/x
k is a constant of proportionality
k=yx
y1x1=y2x2
8(9)=y2(6)
y2=8(9)/6
y2=12

there are 80 people in the audience and 10% have green eyes how many people have green eyes
Answer:
8
Step-by-step explanation:
take the number of people in the audience and multiply by the percent that have green eyes to determine the number with green eyes
80 * 10 %
Change to decimal form
80 *.10
8
Answer:
so, as given 10% have green eyes,
10% of 80
10/100×80
800/100
=8
so 8 people have green eyes

Tabitha was shooting free throws in gym class. She completed 7 of the shots, which was a third of 4 more than Joan completed. What is the number of free throws, n, that Joan completed?]
Answer:
17
Step-by-step explanation:
the following equation can be derived from the question
7 = 1/3(4 + n)
multiply both sides of the question by 3
21 = 4 + n
combine like terms
21 - 4 = n
n = 17

A different car can travel 30.5 miles for every gallon of gas used.
Use proportional reasoning to find the value of x that completes the table showing this relationship.
Answer:
91.5
Step-by-step explanation:
If the table is asking for the amount of miles travelled on 3 gallons of gas, you get 3 * 30.5 = 91.5
This is because one gallon gives 30.5 miles and if you have three gallons, you get 30.5 + 30.5 + 30.5 which is the same as 3 * 30.5
A bag contains 4 red, 2 blue, 6 green and 8 white marbles. What is the probability of selecting a green marble, replacing it, then selecting a red marble
Answer:
14.7%
Step-by-step explanation:
Being that there is 4 red, 2 blue, 6 green, 8 white, that means there is 20 marbles, with 8 success, 8/20. Since the marble is not replaced, that drops it to 7/19 for the second pull. Multiply these together and you get 14.7%.
(8/20)*(7/19)=.147
.147*100=14.7
what is the surface area? 5cm, 4cm, 6cm, 5cm & 5cm
Answer:
To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.
Step-by-step explanation:
SA=2*4*5+2*4*6+2*6*5

Answer:
64%
Step-by-step explanation:
There are 11 containers in total, in which 4 are filled. 11-4=7.
7×100=700÷11=63.6363...
rounded=64
One number is six less than a second number. Twice the first is 4 more than times 6 the second. Find the numbers.
Answer:
[tex]\text{First number: }-10, \\\text{Second number: }-4[/tex]
Step-by-step explanation:
We can write the following system of equations:
Let the first number be [tex]f[/tex] and the second number be [tex]s[/tex]:
[tex]\begin{cases}f+6=s, \\2f-4=6s\end{cases}[/tex]
Solving, we get:
[tex]\int\limits^a_b {x} \, dx \begin{cases}f+6=s, \\2f-4=6s\end{cases},\\2f-4=6(f+6),\\2f-4=6f+36,\\-40=4f,\\f=\boxed{-10}[/tex]
Solving for [tex]s[/tex]:
[tex]f+6=s,\\-10+6=s,\\s=\boxed{-4}[/tex]
Solve for x algebraically, x - 15 < 25
Answer:
x<40
Step-by-step explanation:
x-15<25
Add 15 since addition is opposite of subtraction, thus cancelling the 15 out on both sides.
x-15<25
+15 +15
x<40
