Lewis walked 9/10 of a mile. His friend walked 2/5 of the way with him. How many miles did Lewis's friend walk with him?
Answer:
Lewis's friend walked with him 9/25 miles
Step-by-step explanation:
Given that
Lewis walked 9/10 of a mile
And His friend accompanied him on 2/5 of the way.
This is a simple question of fraction multiplication
The fraction 2/5 has to multiplied with the miles walked by lewis
So
[tex]= \frac{2}{5} * \frac{9}{10}\\=\frac{9}{25}[/tex]
Hence,
Lewis's friend walked with him 9/25 miles

5/3
1 2/3
1) option is correct
9514 1404 393
Answer:
1) 1 2/3
Step-by-step explanation:
The model of choice 1 shows that 3/10 goes into 1/2 one and two-thirds times. That also happens to be the only model with the correct result.
1/2 ÷ 3/10 = 5/10 ÷ 3/10 = 5/3 = 1 2/3
The total surface area of a cube is 96cm2, find its volume.
Answer:
[tex]\huge\boxed{V=64cm^3}[/tex]
Step-by-step explanation:
The formula of a surface area of a cube:
[tex]SA=6a^2[/tex]
The formula of a volume of a cube:
[tex]V=a^3[/tex]
We have
[tex]SA=96cm^2[/tex]
Calculate the edge length (a).
[tex]6a^2=96[/tex] divide both sides by 6
[tex]a^2=16\to a=\sqrt{16}\\\\a=4(cm)[/tex]
Calculate the volume of a cube:

Answer:
D. y=2x-2
Step-by-step explanation:
The format for the equation of a line is y=mx+b, where m is the slope and b is the y-intercept of the line.
The slope of this line is 2
The y-intercept of this line is -2
Therefore, the equation for this line should look like y=2x-2

solve the equation -7(2m-6) + 21=-77
THIS IS FOR 20 POINTS DUE IN 10 MINUTES
TROLL ANSWER WILL GET REPORTED
Answer:
m=10
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−7(2m−6)+21=−77
(−7)(2m)+(−7)(−6)+21=−77(Distribute)
−14m+42+21=−77
(−14m)+(42+21)=−77(Combine Like Terms)
−14m+63=−77
−14m+63=−77
Step 2: Subtract 63 from both sides.
−14m+63−63=−77−63
−14m=−140
Step 3: Divide both sides by -14.
-14m/-14=-140/-14
m=10
Answer:
m =10
Step-by-step explanation:
-14m+42+21=-77
-14m+63= -77
-14m= - 140
m=10

Answer:
3^2*3^4
3^12/3^4
(3^4)^2
The first, fourth, and fifth
Step-by-step explanation:
Follow rules of exponents
When multiply an exponent with same base just add the exponents
EX: 2^2 * 2^2= 2^4
When dividing with the same base, subtract
EX: 3^12/3^2=3^10
When raising the power of an exponent to another exponent, multiply.
EX: (3^2)^2=3^2
Answer:
The correct answer to your problem is
[tex]3^{2} * 3^{6} \\\\\frac{3^{12} }{3^{4}} \\\\(3^{4})^{2}[/tex]
Step-by-step explanation:
You can think of the exponets as it's own number's.
For example the first answer ([tex]3^{2} * 3^{6}[/tex]) 6 + 2 = 8 so your answer [tex]3^{8}[/tex].
The next one [tex]\frac{3^{12} }{3^{4} }[/tex] you would divide 12 by 4 and get 8 giving the answer [tex]3^{8}[/tex].
And finally the last one [tex](3^{4})^{2}[/tex] if you mutiply the exponets 4 and 2 you would get 8 so you answer would be [tex]3^{8}[/tex].

Dani is training for a marathon. Her target speed is 25 miles per hour. She currently runs 15 miles in 1/2 an hour. Does she achieve her target speed for her run?
Answer:
target speed for the marathon has been achieved and exceeded
Step-by-step explanation:
Given that :
Target speed = 25 mph
Current speed = 15 miles in 1/2 an hour
Current speed :
15 miles in 0.5 hours
X miles in 1 hour
0.5x = 15 miles
X = 15 / 0.5
X = 30 miles per hour
Hence, current speed in miles per hour = 30mph
This means that her target speed for the marathon has been achieved and exceeded

Algebra...George bought 2 identical couches and 3 identical chairs. A couch cost twice as much as a chair. He spent $270 more on th ecouches than on the chairs. How much did he spend altogether
Answer:
$1890
Step-by-step explanation:
x= couches
y=chair.
x=2y
2x=3y+270
2(2y) or 4y=3y+270
y=270
x=540
2(540)+3(270)=1890.
Hope this helps :D

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
George bought 2 identical couches and 3 identical chairs.
A couch costs twice as much as a chair.
Let the cost of one couch = 2x
Let the cost of one chair = x
Now,
He spent $270 more on the couches than on the chairs.
This means that,
2(2x) = 270 + 3x
4x = 270 + 3x
Subtract x on both sides.
x = 270
The total spending.
= 4x + 3x
= 4 x 270 + 3 x 270
= 1080 + 810
= $1890
Thus,
The total spending is $1890

Mai and Tyler work on the equation 2/5 b + 1 = -11 together. Mai’s solution is b= -25 and Tyler’s is b = -28 Here is their work. Do you agree with those solutions?
Mai: Tyler:
2/5 b + 1 = -11 2/5 b + 1 = -11
2/5 b = -10 2b + 1 = -55
b = -10 • 5/2 2b = -56
b = - 25 b = -28
Answer:
I disagree with both solutions. The value of b that will make the expression correct is -30
Step-by-step explanation:
Given the equation solved my Mai and Tyler expressed as:
2/5 b + 1 = -11
We are to check the veracity of the solutions;
2/5 b + 1 = -11
Subtract 1 from both sides of the expression
2/5 b + 1 -1 = -11-1
2/5 b = -12
Cross multiply
2b = -12 * 5
2b = -60
Divide both sides by 2
2b/2 = -60/2
b = -30
Since the solution b = -25 and -28 does not tally with the gotten solution, I disagree with the both solutions

Jordan is buying plastic plates for a party.The plates usually cost $2.40 per 10 plates,but they are on sale for 30% off usual price.If jordan buys 50 plates,how much will they cost
30% off means they are paying 70% of the original price.
Sale price = 2.40 x 0.70 = $1.68 for 10 plates
50 plates / 10 = 5
They buy 5 packages of plates.
1.68 x 5 = $8.40
Total price = $8.40
Answer:
Step-by-step explanation:
2.40 X 5 =$12
12 X 0.3=$3.6 off
12-3.6=$8.40
Therefore it'll cost $8.40

The width of a painting is 4 inches less than the length. The frame that surrounds the painting is 2 inches wide and has an area of 240 square inches. What are the dimensions of the painting? (Hint: The total area minus the area of the painting alone is equal to the area of the frame.)
Answer:
131 in²
Step-by-step explanation:
Let x represent the length of the painting. Given that The width of a painting is 4 inches less than the length. Hence:
Width = x - 4
The area of painting = length * width = x(x - 4) = x² - 4x
The frame that surrounds the painting is 2 inches wide (at the top and bottom, left and right). Hence the total width of the frame = (x - 4) + 2 + 2 = x, the length of the frame = x + 2 + 2 = x + 4
The area of the frame = length * breath = x(x + 4) = x² + 4x
Given that the area of the frame = 240 in², hence:
x² + 4x = 240
x² + 4x - 240 = 0
x = -17.62 and x = 13.62
Since the length cannot be negative, hence length = x = 13.62 inches
Area of painting = x(x - 4) = 13.62(13.62 - 4) = 131 in²
