Gina can trade empty bottles for money at the grocery store. She returned a few bottles worth $0.10 each and 6 bottles worth $0.05 each . The clerk paid Gina $0.80 for all of the bottles . How many bottles worth $0.10 did Gina return?
Answer:
5 bottles
Step-by-step explanation:
a total of $0.80 was paid
6 $0.05 bottles were returned= $0.05×6= $0.30
remainder= $0.80-$0.30= $0.50
amount of $0.10 bottles returned= $0.50÷$0.10= 5

Cylinder X and Cylinder Y are similar. The volume of Cylinder Y is 89 in. Find the volume of
Cylinder X

!!
22 cm
Cylinder X
Cylinder Y
O A. 45 cm
OB.
712 cm3
O C.
178 cm3
Answer:
Volume of Cylinder X = 712 cm³
Step-by-step explanation:
Given:
Volume of Cylinder Y = 89 cm³
Radius of cylinder Y = 2 cm
Radius of cylinder X = 4 cm
Find:
Volume of Cylinder X
Computation:
We know that, Cylinder X and Cylinder Y are similar
So,
Volume of Cylinder X / Volume of Cylinder Y = [Radius of cylinder X / Radius of cylinder Y]³
Volume of Cylinder X / 89 = [4/2]³
Volume of Cylinder X / 89 = [2]³
Volume of Cylinder X / 89 = 8
Volume of Cylinder X = 8 x 89
Volume of Cylinder X = 712 cm³
What is v29?
Place a dot on the number line at the best approximation.

6
Answer:
Please read explanations
Step-by-step explanation:
By direct calculations, we know that the nearest perfect square to 29 is 25
The next is 36;
Hence, since 29 is between 25 and 36; it is only proper that the square root of 29 is also between the square roots of both numbers
So, we can conclude that the square root is between 5 and 6
For actual values by calculating, we have this as 5.38 which to the nearest number is 5.4
so, we have the dot at the next 4 small lines after the number 5
A loading ramp is extended from the back of a truck to form a 30° angle with the ground. The truck and the ramp are both on level ground. If the length of the ramp is x feet, how high is the back of the truck from the ground?
A) 2x feet
B) x√3/2
C) x√3
D) x/2
Answer:
Height between ground and truck = 5.5 feet
Step-by-step explanation:
Given:
Angle of elevation = 30°
Length of the ramp = 11 feet
Find:
Height between ground and truck
Computation:
Length of the ramp = Hypotenuse
Height between ground and truck = Perpendicular
Sin θ = Perpendicular / Hypotenuse
Sin 30 = Height between ground and truck / Length of the ramp
0.5 = Height between ground and truck / 11
Height between ground and truck = 0.5 x 11
Height between ground and truck = 5.5 feet

is 4 a factor of 93 explain in words
IM MAKING THE POINTS HIGH
No 4 is not a factor of 93 :)
let me know if this helped<3
Explanation: a factor is whether or not a number can be multiplied with another number, 4 cannot be multiplied by any number to evenly come out as 93, the way you can check this is by dividing 93 by 4, if it comes out as a whole number with no decimal or remainder than the number is a factor if it has a decimal or remainder it is not a factor
Answer:
No.
Step-by-step explanation:
The first method entails simply listing all factors of 93 and then seeing if 4 is one of them. The factors of 93 are 1, 3, 31, and 93. Looking at the list, you see that 4 is not on the list, and the answer to "is 4 a factor of 93?" is therefore no. For the second and perhaps easier method, we divide 93 by 4 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 4 is a factor of 93. If the quotient is a fractional number, then 4 is not a factor of 93. 93 divided by 4 is 23.25 which is a fractional number. Thus, once again, the answer to "Is 4 a factor of 93?" is no.

Write the equation of the line with slope -7/8 and y-intercept of -4/5
Answer:
y= -7/8 - 4/5
Step-by-step explanation:
y=mx+b
y= -7/8 + y intercept (b)
so y= -7/8 - 4/5

) () = 2 − 6 + 13 Translate f(x) 7 units to the left and down 5 units. Write your new function in vertex form
Answer:
[tex]y= (x -4)^2 - 1[/tex]
[tex]Vertex = (4,-1)[/tex]
Step-by-step explanation:
Given
[tex]f(x) = x^2 + 6x+13[/tex]
Required
7 units left and 5 units down
First, we have: [7 units left]
The rule is:
[tex](x,y) \to (x-7,y)[/tex]
So, we have:
[tex]f(x) = (x - 7)^2 + 6(x -7)+13[/tex]
Next, we have: [5 units down]
The rule is:
[tex](x,y) \to (x,y-5)[/tex]
So, we have:
[tex]f'(x) = (x - 7)^2 + 6(x -7)+13 - 5[/tex]
[tex]f'(x) = (x - 7)^2 + 6(x -7)+8[/tex]
Rewrite as:
[tex]y = (x - 7)^2 + 6(x -7)+8[/tex]
Expand
[tex]y = x^2 - 14x + 49 + 6x -42+8[/tex]
Collect like terms
[tex]y = x^2 - 14x + 6x -42+8+ 49[/tex]
[tex]y = x^2 -8x +15[/tex]
To write in vertex form, we have
Subtract 15 from both sides
[tex]y -15= x^2 -8x[/tex]
Divide (-8) by 2; Add the square to both sides
[tex]y -15+ (-8/2)^2= x^2 -8x + (-8/2)^2[/tex]
[tex]y -15+ 16= x^2 -8x + 16[/tex]
[tex]y +1= x^2 -8x + 16[/tex]
Expand
[tex]y +1= x^2 -4x - 4x + 16[/tex]
Factorize
[tex]y +1= x(x -4) -4(x - 4)[/tex]
Factor out x - 4
[tex]y +1= (x -4)(x - 4)[/tex]
Rewrite as:
[tex]y +1= (x -4)^2[/tex]
Make y the subject
[tex]y= (x -4)^2 - 1[/tex]
The vertex is:
[tex]Vertex = (4,-1)[/tex]
Is this a polygon or trapezoid? A. Yes B. No
Answer:
No
Step-by-step explanation:
Look at the shape a polygon is 5 sides while a trapezoid has only 4 sides
Answer:
No. :) Reason: Trapezoids have to have at least on pair of parallel lines; this polygon has none.
In triangle DEF, find the missing side as an exact value:
Answer:
8.60
Step-by-step explanation:
the diagram is optically misleading.
how can the 5 side be longer than the 7 side ?
but ignore that.
the important thing is that this is a triangle with a 90 degree angle.
so, we use Pythagoras' formula : a^2 + b^2 = c^2
we know a and b as 7 and 5.
so, the equation is 7^2 + 5^2 = c^2
=> 49 + 25 = c^2
=> 74 = c^2
=> the missing side length c is
[tex] \sqrt{74} = 8.60[/tex]

Which number is the numerator in the fraction 1/2
Answer:
1
Step-by-step explanation:
The denominator is the bottom number, and represents how many parts are possible—in other words, how many parts go into a whole. The numerator is the top number, and represents how many parts you have.
[tex]\frac{Numerator}{Denominator}[/tex]
Answer:
The numerator is 1.
Step-by-step explanation:
The numerator is the number above the fraction bar; the denominator is below.

What is the equation of the following line? Be sure to scroll down first to see all answer options. (0, 0) (3,-9)
Answer:
Equation to find the slope
[tex]\frac{y2-y1}{x2-x1} =\frac{-9-0}{3-0} = -9/3 = -3x[/tex]
y=-3x
hope that answers your question
Step-by-step explanation:
Answer: C. y = -3x
Step-by-step explanation:
Since the line runs through the origin (0, 0), we don't have to write a y-intercept. To calculate the slope, we determine the change in y value over the change in x value.
Looking at the graph, we see that for every +1 x, we have -3 y, so the slope is -3, which we multiply by x in the equation.
