10 is 6% of what number
Answer:
166.67
Step-by-step explanation:
We have, 6% × x = 10 or, 6/100 × x = 10
Multiplying both sides by 100 and dividing both sides by 6,
we have x = 10 × 100/6
x = 166.67
If you are using a calculator, simply enter 10 × 100 ÷ 6, which will give you the answer.
Hope this helps

Find the solution of the system of equations.
4x – 8y = -44
2x + 4y = -6
Answer:
x= -7/2
y= 5/4
Step-by-step explanation:
x-2y=-11
x+2y = -6
then isolate x and set equal to each other
-2y - 6 = 2y -11
4y = 5
y = 5/4
then solve for x using y.
x+5/2 = -6
x = -7/2

A leaky valve on the water meter overcharges Ahmed for one Liter of water for every 2 months. The overcharged amount w varies directly with time t . (a) Find the equation that models the variation . (b) Solve the equation to find the number of months it will take for Ahmed to be overcharged for 10 liters of water leaked. Show all your steps
Answer:
20 months
Step-by-step explanation:
A leaky valve on the water meter overcharges Ahmed for one Liter of water for every [tex]2[/tex] months. The overcharged amount [tex]w[/tex] varies directly with time [tex]t[/tex].
(a)
As the overcharged amount [tex]w[/tex] varies directly with time [tex]t[/tex],
[tex]w=kt[/tex]
Here, [tex]k[/tex] is a constant.
A leaky valve on the water meter overcharges Ahmed for one Liter of water for every [tex]2[/tex] months.
Put [tex]w=1\,,\,t=2[/tex]
[tex]1=2k\\k=\frac{1}{2}[/tex]
So,
[tex]w=\frac{t}{2}[/tex]
(b)
To find the number of months it will take for Ahmed to be overcharged for 10 liters of water leaked, put [tex]w=10[/tex] in [tex]w=\frac{t}{2}[/tex]
[tex]10=\frac{t}{2}\\\\t=10(2)\\[/tex]
[tex]t=20[/tex] months

9. Bella hiked a 13-kilometer trail at Great Peak. How many meters did Belle
hike? 1km = 1,000m
A 0.13
B 0.013
C 1,300
D 13,000
9.)
Answer:
D. 13,000
Step-by-step explanation:
If there are 1,000 m in 1 km, we can find the number of meters she hiked by multiplying 13 by 1,000:
13(1000)
= 13,000
So, Belle hiked 13,000 meters.
The correct answer is D. 13,000

Write the equation of the line in Slope-Intercept form that passes through the point (4,-7) and has the same slope as y=1/4 x +3
Answer:
Step-by-step explanation:
y + 7 = 1/4(x - 4)
y + 7 = 1/4x - 1
y = 1/4x - 8
What is the quotient? X+5√3x^2+4x+5 A.) 3x^2-11+60/x+5 B.) 3x-11+60/x+5 C.) 3x^2-11-50/x+5 D.) 3x-11-50/x+5 Please hurry this is timed!
Answer:
[tex]3x - 11[/tex]
Step-by-step explanation:
Given
[tex]\frac{3x^2 + 4x + 5}{x + 5}[/tex]
Required
Determine the quotient
First, we check if the divisor (x + 5) can divide the dividend (3x^2 + 4x + 5) without having a reminder
Equate the denominator to 0.
[tex]x + 5 = 0[/tex]
[tex]x = -5[/tex]
Substitute -5 for x in the numerator
[tex]3x^2 + 4x + 5 = 3*(-5)^2 + 4 * (-5) + 5[/tex]
[tex]3x^2 + 4x + 5 = 60[/tex]
This means that it has a reminder of 60
To get the quotient, we subtract 60 from the numerator and evaluate
[tex]\frac{3x^2 + 4x + 5}{x + 5}[/tex] becomes
[tex]\frac{3x^2 + 4x + 5 - 60}{x + 5}[/tex]
[tex]\frac{3x^2 + 4x - 55}{x + 5}[/tex]
Expand the numerator
[tex]\frac{3x^2 + 15x - 11x - 55}{x + 5}[/tex]
Factorize:
[tex]\frac{3x(x + 5) - 11(x + 5)}{x + 5}[/tex]
Factor out x + 5
[tex]\frac{(3x- 11)(x + 5)}{x + 5}[/tex]
Cancel out x + 5
[tex]3x - 11[/tex]
Hence, the quotient is [tex]3x - 11[/tex]

Find two integers whose sum is 20 and product is 99
Answer:
11 and 9
Step-by-step explanation:
X+Y=20
X*Y=99
Y=20-X
X*(20-X)=99
20X-X^2=99
20X-X^2–99=0
-(X - 11) (X - 9) = 0
Two solutions
X-11=0, X=11
X-9=0, X=9
Y=20-X, so if X is 9, Y is 11
Y=20-X, so if X is 11, Y is 9
The two numbers are 11 and 9

Tom and Brian are hiking towards each other at the opposite ends of a trail that is 21 miles long. Tom hikes uphill at a speed of 2 miles per hour. Brian is hiking downhill at a speed of 4 miles per hour. How long will it take for the two to meet?
Answer:
3.5 hours
Step-by-step explanation:
Distance = 21 miles
Speed * time
Speed * time = distance
Tom speed = 2 mph
Brian = 4 mph
Let time = t
Brian distance + Tom's distance = total distance
4t + 2t = 21
6t = 21
t = 21 / 6
t = 3.5 hours
