Ella's grandmother sewed her a change purse. When she gifted it to her, Ella counted 23 coins already in it. Ella noticed there were only dimes and quarters worth $4.70. How many dimes were in the change purse?
Answer:
16 quarters and 7 dimes
Step-by-step explanation:
16*25 = 400 (or 4 dollars)
7*10 = 70 (or 70 cents)
400+70 = 470 (or $4.70)
Q.10 The cost of a magazine is $x and the cost of a newspaper is $(x -3). The total cost of 6 magazines and 9 newspapers is $51. Write down and solve an equation in x to find the cost of a magazine,
Answer and Step-by-step explanation:
The cost of all the 6 magazines are: 6x
The cost of all the 9 newspapers are 9(x-3)
So, the total cost is the sum of all the items:
6x + 9(x-3) = 51
6x + 9x - 27 = 51
15x = 78
x = 5.2
Since the cost of one magazine is $x, the cost will be $5.20.

Item 4 Pete wants to mix 4 quarts of 20% orange juice concentrate with some 60% pineapple juice concentrate to get a 50% punch concentrate for a party. How much of the 60% pineapple juice concentrate should be used? (OMIT THE UNIT FOR YOUR ANSWER - ENTER THE NUMERIC VALUE ONLY.)
Answer:
12 quarts of 60% pineapple juice concentrate should be used
Step-by-step explanation:
Let the amount for the 60% be x
20% of 4 + 60% of x = 50% of (x + 4)
So we have;
0.2(4) + 0.6(x) = 0.5(x + 4)
0.8 + 0.6x = 0.5x + 2
0.6x-0.5x = 2-0.8
0.1x = 1.2
x = 1.2/0.1
x = 12

Answer:
The answer is A.(-4,3)
Step-by-step explanation:
Multiply the first equation by -3,and multiply the second equation by 1.
−3(x+y=−1)
1(3x−4y=−24)
Becomes:
−3x−3y=3
3x−4y=−24
Add these equations to eliminate x:
−7y=−21
Then solve−7y=−21for y:
−7y=−21
[tex]\frac{-7y}{-7} =\frac{-21}{-7}[/tex]
y=3
Now that we've found y let's plug it back in to solve for x.
Heres our original equation
x+y=−1
Substitute 3 for y in x+y=−1:
x+3=−1
x+3+−3=−1+−3(Add -3 to both sides)
x=-4

answer is A)

Step-by-step explanation:
A can of tuna fish has a diameter 11.4 cm and height 3.7 cm. Cans are packed snugly for shipping in boxes containing 4 layers of 5 rows by 7. How much empty space does each box contain?
Answer:
14447 cm³
Step-by-step explanation:
Given that:
Diameter = 11.4cm
Height = 3.7cm
boxes has 4 layers ; 5 rows by 7
Hence, dimension of shipping boxes :
Height = height of can * layer = 3.7 * 4 = 14.8 cm
Length = 5 * diameter of can = 5 * 11.4 = 57cm
Width = 7 * diameter of can = 7 * 11.4 = 79.8 cm
Volume of shipping boxes :
Height * Length * Width
14.8 * 57 * 79.8 = 67319.28 cm³
For fish can:
Radius = diameter / 2 = 11. 4 / 2 = 5.7cm
Volume (V) of can = pi*radius^2*height
V = π * 5.7^2 * 3.7 = 377.66027 cm³
Total volume of cans = number of cans * V
Total volume of cans = (4 * 5 * 7 * 377.66027)
Total volume of cans = 52872.4378 cm³
Empty space = difference in volume
= 67319.28 - 52872.4378
= 14446.8422
= 14447 cm³ (approx)

What is the x-intercept and the y-intercept of the graph of 6x - 12y = 36? Please explain your answer in full sentences.
Sentence Frame: I found the x-intercept by...and I found the y-intercept by...
Answer:
Sentence Fram: I found x-intercept by substitute y by 0 and I found y-intercept by substitute x by 0
x-intercept = (6, 0), y-intercept = (0, -3) ⇒ C
Step-by-step explanation:
To find the x-intercept of a line, equate y in its equation by 0To find the y-intercept of a line, equate x in its equation by 0∵ The equation of the graph is 6x - 12y = 36
→ Equate y by 0 to find x
∵ y = 0
∴ 6x - 12(0) = 36
∴ 6x - 0 = 36
∴ 6x = 36
→ Divide both sides by 6 to find x
∴ x = 6
∴ The x-intercept = (6, 0)
→ Equate x by 0 to find y
∵ x = 0
∴ 6(0) - 12y = 36
∴ 0 - 12y = 36
∴ -12y = 36
→ Divide both sides by -12 to find y
∴ y = -3
∴ The y-intercept = (0, -3)
∴ Sentence Fram: I found x-intercept by substitute y by 0 and I found
y-intercept by substitute x by 0
∴ x-intercept = (6, 0), y-intercept = (0, -3)
Find the vertex.
4) y=-2x^2-8x-6
Answer:
Vertex: (-2, 2)
Step-by-step explanation:
The x-coordinate of the vertex would be as follows;
x = -b/2a = 8/2(-2) = -8/4 = -2
respectively the y-coordinate of the vertex would be y(-2) = -2(-2)^2 - 8(-2) - 6 = -2(4) + 16 - 6 = - 8 + 10 = 2
Your vertex would be a maximum of (-2, 2)
* I say maximum as the coefficient of x^2 is -2, and it is less than zero so the parabola opens downward

L Pretest Unit 2
Question 10 of 20
Which unit of measure would be appropriate for the volume of a cube with an
edge length of 5 centimeters?
A. Centimeters
B. Meters
C. Cubic centimeters
D. Square centimeters
Answer:
Option (c) is correct.
Step-by-step explanation:
The edge length of a cube is 5 cm.
We need to find the volume of the cube.
The formula for the volume of a cube is given by :
[tex]V=a^3[/tex]
Put a = 5 cm in above formula
[tex]V=(5)^3\\\\=125\ cm^3[/tex]
Hence, cubic centimeters is the appropriate unit for measuring the volume of a cube.
