The ratio of peaches, plums and pears is 1:4:2
respectively. If the total number of fruits is 63, how many
plums are there?
Number of plums =
Answer: 36 plums
Step-by-step explanation:
1+4+2 = 7
7 units
63 = 7 units
divide by 7 on both sides
9 = 1 unit
plums = 4 units
4*9 = 36
36 plums
Mr. Alvarado needs 15 1/8 pounds of chicken feed to fill his feeder. He has one bag of chicken feed that weighs 3 1/2 pounds and another bag of chicken feed that weighs 2 3/4 pounds. How many more pounds of chicken feed does Mr. Alvarado need to fill the chicken feeder?
A: 9 1/8 Lbs
B: 8 7/8 Lbs
C: 9 7/8 Lbs
D: 6 1/4 Lbs
Answer:
B: 8 7/8 Lbs
Step-by-step explanation:
answer = [tex]15\frac{1}{8} -3\frac{1}{2} -2\frac{3}{4}[/tex]
step 1 find a common denominator
common denominator - 8
* apply *
[tex]\frac{1^*^1}{8^*^8} =\frac{1}{8} \\\\\frac{1^*^4}{2^*^4} =\frac{4}{8} \\\\\frac{3^*^2}{4^*^2} =\frac{6}{8}[/tex]
now we have
[tex]15\frac{1}{8} -3\frac{4}{8} -2\frac{6}{8}[/tex]
step 2 make each fraction a improper fraction
We can do this my multiplying the big number by the denominator and adding that to the numerator.
[tex]15*8=120\\120+1=121\\\frac{121}{8} \\\\3*8=24\\24+4=28\\\frac{28}{8} \\\\2*8=16\\16+6=22\\\frac{22}{8}[/tex]
now we have
[tex]\frac{121}{8} -\frac{28}{8} -\frac{22}{8}[/tex]
Now we can subtract
remember when subtracting fractions you only subtract the numerators. ( so we keep the denominator as 8 )
so 121 - 28 - 22 = 71
so the answer is [tex]\frac{71}{8}[/tex]
finally we want to change the answer back into a mixed fraction
To do this we divided 71 and 8
8 can go into 71 8 times
8 * 8 = 64
71 - 64 = 7
We're left with [tex]8\frac{7}{8}[/tex]

4. The ratio of skateboards to bikes is 3:1.
If there are 12 skateboards, how many
bikes are there?
A 1
B 2
C3
D4
Answer quick PLZZ no website
Answer:
D
Step-by-step explanation:
3 represents skateboards and 1 represents bikes. We need to get from 3 to 12 and 1 to the answer by using the same number you used to get from 3 to 12.
To get from 3 to 12 you multiply by 4
3*4=12
So let's go ahead and multiply 1 by 4 as well
1*4=4
Your ratio is now 12:4 and 4 stands for bikes so there are 4 bikes

Answer:
I tjink think the answer is 11/2(5+2 1/2)
need help ! please give a answer :)
Can someone help me here.
Answer:
A
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
3x - 2y = 12
-2y = -3x + 12
2y = 3x - 12
y = 3/2x - 6
Slope is 3/2
Y-intercept is -6

Jenny walked 2 miles on Monday and 1 miles on Tuesday. How many 3 8 7 8 miles did she walk on Monday and Tuesday all together?
Correct Question is:
Jenny walked 2 3/8 miles on Monday and 1 7/8 miles on Tuesday. How many miles did she walk on Monday and Tuesday all together? What number model would you use?
a. 2 3/8 - 1 7/8
b. 2 3/8 + 1 7/8
c. 23/8 + 17/8
d. none of these
Answer:
b. 2 3/8 + 1 7/8
Step-by-step explanation:
As the sum of both Monday and Tuesday miles are required therefore both fractions will be added up as mentioned in option B of the question.
remaining are wrong as both fractions cannot be subtracted, and option c is wrong because 2 (3/8) is not equals to 23/8 and 1 (7/8) is not equals to 17/8.
A coin has two sides: heads and tails. A die has six sides, numbered 1 through 6 . If you flip the coin and roll the die, what is the probability that you flip ''heads'' and roll a number less than 3?
Answer:
Step-by-step explanation:
A number less than 3 is 2 or 1 which is 2/6 of the time
A coin can land on either side with a probability of 1/2
P(h and <3) = 1/2 * 2/6 = 1/6
This is exactly what you got.

Answer: True for all x
Step-by-step explanation:
4x - 6 + 2x = 3(2x-2)
Group Like Terms: 4x+2x - 6 = 3(2x-2)
Add Similar Elements (4x+2x=6x): 6x - 6 = 3(2x-2)
Expand: 3(2x-2) ; 6x - 6
6x - 6 = 6x - 6
Add 6 to Both Sides: 6x - 6 + 6 = 6x - 6 + 6t: 6x - 6x = 6x - 6x
Simplify: 6x = 6x
Subtract: 6x - 6x
Simplify: 0 = 0
Both sides are equal in this equation, therefore all values for x is true.

Write an equation of the line that passes through the given point and is perpendicular to the given line. 1 (-6, -4); y = 3x + 1
Answer:
y= -1/3x - 6
Explain:
For the slope, you find the opposite reciprocal of the given slope. Then you plug in the given coordinates into the point-slope formula: y - y = m ( x - x ). So the expression would be y - (-4) = -1/3 ( x - (-6)). So the answer would be y = -1/3x - 6.

perimeter of a rectangle is 42 CM if length is 6 CM then breadth
Answer:
15cm
Explanation:
the formula for calculating the perimeter of a rectangle is (length + breadth) ÷ 2. so, we can divide the given perimeter by 2 to find the sum of the length and breadth of the rectangle:
42 ÷ 2 = 21cm
now, since we know the length of the rectangle is 6cm, we can subtract it from the sum of the length and breadth:
21 - 6 = 15cm
thus, the breadth of the rectangle is 15cm.

Sheila works at a fine jewelry store and earns a commission on her total sales for the week. She earned $900 in commission this week. She sold $23,000 worth of jewelry to earn that commission. Express her rate of commissions a percent.
Answer:
3.913%
Step-by-step explanation:
We are given that Sheila earned is commission $900 for selling $23,000 worth of jewelry, and we are asked to find the rate of her commissions as a percent.
The rate of commissions would basically just be what percent of the money made does she get. Since Sheila sold $23,000 worth of jewelry and got $900 for doing so, her rate of commission would be:
900 ÷ 23,000 ≈ 0.03913
Which expressed as a percent is:
3.913%
So her rate of commissions would be 3.913%.
