Given:
The ratio of red and blue cubes is 4:7.
After adding 10 more red cubes the ratio of red and blue cubes is 6:7.
To find:
The number of blue cubes.
Solution:
The ratio of red and blue cubes is 4:7.
Let the number of red and blue cubes be 4x and 7x respectively.
After adding 10 more red cubes.
Number of red cubes = 4x+10
Then, the ratio of red and blue cubes is 6:7.
[tex]\dfrac{4x+10}{7x}=\dfrac{6}{7}[/tex]
[tex]7(4x+10)=6(7x)[/tex]
[tex]28x+70=42x[/tex]
[tex]70=42x-28x[/tex]
[tex]70=14x[/tex]
Divide both sides by 14.
[tex]5=x[/tex]
Now,
Number of blue cubes in the bag is
[tex]7(5)=35[/tex]
Therefore, the number of blue cubes is 35.

The distance from Matt’s home to school is 5/8 of a mile. He has biked 3/8 of a mile. How much further does he have to bike?
Given:
The distance from Matt’s home to school is [tex]\dfrac{5}{8}[/tex] of a mile.
He has biked [tex]\dfrac{3}{8}[/tex] of a mile.
To find:
How much further does he have to bike?
Solution:
We have,
Total distance from Matt’s home to school = [tex]\dfrac{5}{8}[/tex] of a mile.
Distance covered = [tex]\dfrac{3}{8}[/tex] of a mile.
Remaining Distance = [tex]\dfrac{5}{8}-\dfrac{3}{8}[/tex] of a mile
= [tex]\dfrac{5-3}{8}[/tex] of a mile
= [tex]\dfrac{2}{8}[/tex] of a mile
= [tex]\dfrac{1}{4}[/tex] of a mile
Matt has [tex]\dfrac{1}{4}[/tex] mile left to bike.
Therefore, the correct option is A.
What is a slope of a line parallel to the line whose equation is Y - X = 5
A) -1
B) 1/5
C) 1
D) 5
Answer:
C
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
y - x = 5 ( add x to both sides )
y = x + 5 ← in slope- intercept form
with slope m = 1
Parallel lines have equal slope, thus
the slope of a parallel line is m = 1 → C
Solve: 5/2x - 1/3= -1/2
A. x=-5/12
B. x= -25/12
C. x= -1/15
D. x= 1/3
Answer:
c. x = -1/15
Step-by-step explanation:
5/2x - 1/3 = -1/2 [multiply the whole equation by 6 (lowest common denom)
15x - 2 = -3 [add 2 on both sides of equation
15x = -1 [divide both sides by 15 to isolate x]
x = -1/15

Cal Amity found that 24% of his sample answered "yes" to the third survey question, which was, "Have you done anything, or will you do anything, to prepare any other part of your home before Gourmando's visit?" (880 Surveyed)
Mr. Amity can infer that, most likely, between _[blank A]_ and _[blank B]_ inhabitants of the Kingdom have done, or will do something, to prepare another part of their homes before Gourmando's visit.
880 were surveyed.
24% answered yes.
Multiply number of surveyed by percentage that said yes:
880 x 0.24 = 211.2
Since the answer has a decimal, the number of people would be the whole number above and below the decimal.
The answer is between 211 and 212
Answer:
Let the number of people answered "yes" be x
[tex]24\% \: of \: 880 \\ \frac{24}{100} \times 880 = 211.2 = 211(approx)[/tex]

An ant carries food at a speed of 0.01 m/s. How long will it take the ant to carry a cookie crumb to the ant hill, a distance of 50 m? Express your answer in hours.
Answer:
5000 seconds
Step-by-step explanation:
0.01*100=1
100*50=5000
Answer:
about 1.4 hours

The weight of an object on Mars varies directly with its weight on Earth.An object that weighs 50 pounds on mars weighs 150 on Earth.If an object weighs 120 pounds on Earths,write and solve a direct variation equation to find how much an object would weigh on mars.
Answer:
Formula: y = x/3. Answer: 40 pounds.
Step-by-step explanation:
To solve this, we divide 150 by 50. This gets us 3. This means your weight on Earth is 3x your weight on Mars. That means we can make a formula. Our formula is y (weight in pounds on Mars) = x (weight in pounds on Earth)/3. Let's plug 120 in our formula. 120/3 is 40. This means the weight of the object on Mars is 40 pounds.

I need to simplify the complex fraction.
Answer:
(15 – 22x)/4x(2x – 5)
Step-by-step explanation:
Let us take the numerator first:
(1/2x – 5) – (7/8x – 20) = (1/(2x – 5)) – (7/4(2x –5)) = (8x – 20 – 7(2x – 5))/(4(2x – 5)(2x – 5)
= (8x – 20 – 14x + 35)/4(2x – 5)² = (15 – 22x)/4(2x – 5)²
The denominator is: x/2x – 5
So we now have:
(15 – 22x)/4(2x – 5)² ÷ x/(2x – 5) = (15 – 22x)/4(2x – 5)² x (2x – 5) /X = (15 – 22x)/4x(2x – 5)

Step-by-step explanation:
Chloe charged for admission to her play on three different nights. Each night, a
different number of people were in attendance, but remarkably, Chloe collected
S541 each night. If the admission charges for each child and each adult were $9
and S17, respectively, how many people in total came to the three showings?
Answer:
The number of people in total that came to the three showings is 138 people
Step-by-step explanation:
The amount Chloe collected each night for admission to her play = $541
The admission charge for each child = $9
The admission charge for each adult = $17
The number of people attending the play each of the three nights are different
Let x represent the number of children that attend the play on the first night and ley y represent the number of adults that attend, we have;
9·x + 17·y = 541
For the second night, we have;
9·a + 17·b = 541
For the third night, we have;
9·c + 17·d = 541
27·(x + a + c) + 51·(y + b + d) = 1,623
Using Microsoft Excel, where we create a series with the first term = 541 and the common difference, d = -9 and number the adjacent column serially from 1 to 61 and the on the right column we divide the created series by 17 then we search for the whole number combinations, we get three possible combinations as follows;
12 children and 26 adults
29 children and 17 adults
46 children and 8 adults
Therefore, the number of people in total that came to the three showings = 12 + 26 + 29 + 17 + 46 + 8 = 138
The number of people in total that came to the three showings = 138 people.

Answer:
128
Step-by-step explanation:
If you start off with 4 and it doubles every day, by day two you would have 8 spores then by day three you will have 16 because it doubles itself. Day four you have 32, day 5 you will have 64 and finally day 6 you will have 128

Complete question is;
Mika taught her sister the steps for dividing a decimal by a decimal. Which instructions are correct?
A) 1. Multiply the divisor by a multiple of 10 to create an integer divisor. 2. Multiply the dividend by the same multiple of 10 as step 1. 3. Divide, and apply the rules for dividing signed numbers.
B) 1. Multiply the dividend by a multiple of 10 to create an integer. 2. Multiply the divisor by the same multiple of 10 as step 1. 3. Divide, and apply the rules for dividing signed numbers.
C) 1. Divide the divisor by a multiple of 10 to create an integer divisor. 2. Divide the dividend by the same multiple of 10 as step 1. 3. Divide, and apply the rules for dividing signed numbers.
D) 1. Divide the dividend by a multiple of 10 to create an integer. 2. Divide the divisor by the same multiple of 10 as step 1. 3. Divide, and apply the rules for dividing signed numbers.
Answer:
A) 1. Multiply the divisor by a multiple of 10 to create an integer divisor. 2. Multiply the dividend by the same multiple of 10 as step 1. 3. Divide, and apply the rules for dividing signed numbers.
Step-by-step explanation:
In Mathematics, divisor is the number by which the dividend should be divided.
Now, if we want to divide a decimal by another decimal, to make things easy we have to transform both numbers from decimals to integer form to make direct division easier.
The first step will be to multiply the divisor by a multiple of 10. The multiple of 10 will depend on the number of decimal places.
The second step is to do the same to the dividend.
The last step would be to divide the integers by applying rules of division of numbers.
The correct option is Option A:
