In a bag of marbles, the ratio of the number of blue to red to white is 13:2:6. If the number of blue marbles minus the number of white marbles is 21, how many red marbles are there?
Answer: There are 6 red marbles
Step-by-step explanation:
13 - 6 = 7
21/7 = 3
3 x 2 = 6
To check the answer:
13 x 3 = 39
6 x 3 = 18
39 - 18 = 21
Answer:
6
Step-by-step explanation:
Blue = 13x
Red = 2x
White = 6x
Now, they have given one more info:
Blue - White = 21
So, 13x - 6x = 21
7x = 21
x = 3
∴ Now, Blue = 13*3 = 39
Red = 2*3 = 6
White = 6*3 = 18
Total = 63

A triangle with a height of 8 mm and a base of 7 mm has an area of what?
Group of answer choices
56 mm squared
28 mm squared
87 mm squared
15 mm squared
Thanks so much!
Answer: 28 mm squared
Answer:
area of ∆ = 1/2 × base × height
base = 7mm
height = 8mm
Putting in the formula,
1/2 × 8 × 7 = 4 × 7 = 28mm²
Area of ∆ = 28mm²

Elizabeth is thinking of a two-digit number. When the tens digit is subtracted from the ones digit, the difference is 2. One-fifth of the number is 1 less than the sun of the digits. What is the number?
Answer:
35
Step-by-step explanation:
The answer is 35 because 5-3=2. And 5+3=8. 1/5 of 35 is 7 which is one digit less than 8.
:)
I hope this helps!
Answer:
35
Step-by-step explanation:
Let's start by placing 35 in the spot for x. When the tens digit (3) is subtracted from the ones digit (5), the difference is two. Let's see if it works. 5-3=2. So far, we're good! Now one-fifth of 35 is 7, which, is 1 less than the sum of both 5 and 3 which is 8. 8-1=7.

Determine if the table shows a proportional relationship.
x 36.5 23.2 63.3
y 18.25 11.6 21.1
Group of answer choices
a. Yes, it is proportional because the ratios for y over x are all equivalent to one-half.
b. Yes, it is proportional because the ratios for y over x are all equivalent to one-third.
c. No, it is not proportional because 18.25 over 36.5 is not equal to 23.2 over 11.6.
d. No, it is not proportional because 18.25 over 36.5 is not equal to 21.1 over 63.3
Answer:
Because 18.25/36.5 and 21.1/63.3, the numbers in the table do not represent a proportionate connection. First set of data: y/x = 18.25/36.5 = 0.5
Values for the second pair are: y/x = 11.6/23.2 = 0.5
Values for the third pair are: y/x = 21.1/63.3 = 0.3
Because the value of y/x varies among the table's values, the table does not depict a proportionate connection. A value table must have an identical ratio of y/x between each pair of values for a proportional relationship to be seen. K, or the proportionality constant, is the constant.
Because 18.25 over 36.5 is not equivalent to 21.1 over 63.3, we may conclude that: D. No, does not demonstrate a proportionate connection.

You bought some jeans for $55. Today they were on sale for $49.50. What was the percent decrease in price?
10% decrease
Explain how you these answers are right
Answer:
Step-by-step explanation:
Profit % = [tex]\frac{New Value - Old Value}{Old value}[/tex]x 100
Loss % = [tex]\frac{Old Value-NewValue}{Old Value}[/tex]
Profit % = [tex]\frac{16.1-5}{5}[/tex] × 100
= [tex]\frac{11.1}{5}[/tex] x 100
= 11.1 x 20
= 222% increase
∴ Hence, proved that the answer is correct.
Profit % = [tex]\frac{57.6-40}{40}[/tex]×100
= 44% increase
∴ Hence, proved that the answer is correct.
Profit % = [tex]\frac{63.6-60}{60}[/tex]x 100
= 6% increase
∴ Hence, proved that the answer is correct.
Loss % = [tex]\frac{110-13.2}{110}[/tex]x 100
= 88% decrease
∴ Hence, proved that the answer is correct.
Loss % = [tex]\frac{55-49.5}{55}[/tex]x 100
= 10% decrease
∴ Hence, proved that the answer is correct.

Answer:
Step-by-step explanation:
Old Value: 5
New Value: 16.1
16.1-5=11.1
11.1 divided by 5= 2.22
2.22/1 x 100=222%
222% increase
Old Value: 40
New Value: 57.6
57.6-40=17.6
17.6 divided by 40= 0.44
0.44/1 x 100= 44%
44% increase
Old Value: 60
New Value: 63.6
63.6-60=3.6
3.6 divided by 60= 0.06
0.06/1 x 100= 6%
6% increase
Old Value: 110
New Value: 13.2
13.2-110= -96.8
-96.8 divided by 110= -0.88
-0.88/1 x 100= 88%
88% decrease

Adrien has 4 liters of milk. He drinks y liters each day.
a) If Adrien has x liters of milk left after one week, express x in terms of y.
b) State the independent and dependent variables in the equation.
The requried solutions are as follows,
(a) Equation x in terms of y is given as x = 4 - 7y.
(b) In the equation x is the dependent variable and y is the independent variable.
The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here
Adrien has 4 liters of milk. He drinks y liters each day.
Adrien has x liters of milk left after one week
So
x = 4 - 7y
In the above equation model, it is clear that x changes as y changes, although x is the dependent variable and y is the independent variable.

why are fifteenths show in the example model?
Answer: Fifteenths are shown in the example model because the denominator of your answer is also 15.
Step-by-step explanation:
Like what I'm trying to say is is that this is common sense and also I don't know why your math book would want you to solve this but, since the answer is 6/15 then it wouldn't make sense for your answer table to have 16 spaces instead of 15. Like common sense, although I can get why you're confused.
