Answer:
85.75 cubic units
Step-by-step explanation:
You got the formula [tex]V=2s^3[/tex] and you know that s = 3.5 units
The only thing you need to do is to substitute the value of s in your formula. This is
[tex]V= 2(3.5)^3[/tex]
And you need to do all the operations
[tex]V= 2(3.5)^3 = 2(42.875) = 85.75[/tex]
And your answer is D
The value of V for s = 3.5 units is,
⇒ V = 85.75 cubic units
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
The equation below shows the total volume (V),in cubic units, of 2 identical boxes with each side equal to s units as,
⇒ V = 2s³
Here, We have;
s = 3.5 units
Hence, We get;
⇒ V = 2s³
⇒ V = 2 × 3.5³
⇒ V = 85.75 cubic units
Thus, The value of V for s = 3.5 units is,
⇒ V = 85.75 cubic units

An 8-ounce can of tomatoes costs $1.14.A 12-ounce can costs $1.75.Which can of tomatoes cost the least per ounce
Answer:
8-ounce can tomatoes costs the least per ounce.
Step-by-step explanation:
Cost of an 8-ounce can of tomatoes = $1.14
cost per ounce of tomatoes = [tex]\frac{1.14}{8}[/tex]
= $0.1425 ≈ $0.14 per ounce
Cost of an 12-ounce can of tomatoes = $1.75
cost per ounce of tomatoes = [tex]\frac{1.75}{12}[/tex]
= $0.1458 ≈ $0.15 per ounce
Therefore, 8-ounce can of tomatoes cost the least per ounce.

Ling uses 21 bananas to make 7 fruit smoothies. What is the unit rate that Ling uses for bananas per each smoothie? What is the unit rate? Explain how to use equivalent fractions to find the answer
Answer:
The unit rate that ling uses for bananas per each smoothie is (3/1) bananas per smoothie
Step-by-step explanation:
Ling uses 21 bananas to make 7 fruit smoothies. Total of bananas B = 21. Total of smoothies S =7.
The unit rate U is the relationships B divided by S.
U = B/S
U = 21 bananas / 7 smoothies
U = 21/7 Bananas per smoothies.
We can use the equivalent fractions to find the unit rate. 21 can be expressed as 7*3. 7 can be expressed as 7*1. We can simplify the number 7 in numerator and denominator.
U = (7*3)/(7*1)
U = 3/1.
Finally, the unit rate is 3/1 bananas per smoothie.

Balu and Pumba shared ½ of a cake. Balu got to eat twice as much cake as Pumba. What fraction of the whole cake did Balu eat?
Answer:
Balu ate [tex]\frac{1}{3}[/tex]fraction of the whole cake
Step-by-step explanation:
Let x be the amount of cake eaten by Pumba
Balu got to eat twice as much cake as Pumba.
Balu eat cake = 2x
Balu and Pumba shared ½ of a cake.
So, [tex]2x+x=\frac{1}{2}[/tex]
[tex]3x=\frac{1}{2}[/tex]
[tex]x=\frac{1}{6}[/tex]
So, Pumba's share = [tex]\frac{1}{6}[/tex]
Balu's share = 2x = [tex]\frac{2}{6}=\frac{1}{3}[/tex]
Hence Balu ate [tex]\frac{1}{3}[/tex]fraction of the whole cake

Final answer:
The equation solved for w is B. w = lh/v
Explanation:
1. Understand the Formula:
The formula for the volume (V) of a rectangular prism is V = lwh, where l is the length, w is the width, and h is the height.2. Isolate w:
To solve for w, isolate w on one side of the equation.Divide both sides of the formula by lh: V/lh = w3. Determine the Correct Equation:
Compare the isolated w with the provided answer choices.The correct equation solved for w is w = lh/vTherefore, the correct answer will be B. w=lh/v
A spider walks about 19 cm each second. About how long would it take the spider to walk around the perimeter of a room that is 3 m wide and 4 m long?
Final answer:
To calculate the time it takes the spider to walk around the perimeter of a 3 m by 4 m room, we first find the perimeter in meters, convert it to centimeters, and then divide by the spider's speed in cm/s. The perimeter of the room is 14 m, which is 1400 cm. Dividing this by the spider's speed, 19 cm/s, gives us approximately 74 seconds.
Explanation:
To find out how long it would take the spider to walk around the perimeter of a room that is 3 m wide and 4 m long, we first need to calculate the perimeter of the room. The formula for perimeter P of a rectangle is P = 2(l + w), where l is the length and w is the width.
So for a room that is 3 m wide and 4 m long, the perimeter is:
P = 2(4 m + 3 m) = 2(7 m) = 14 m
Since the spider walks 19 cm each second and there are 100 cm in a meter, we convert the perimeter to centimeters:
14 m = 1400 cm
Now, we calculate the time t it will take for the spider to walk this distance by dividing the perimeter by the spider's speed:
t = perimeter/speed = 1400 cm / 19 cm/s
Therefore, the time taken for the spider to walk around the perimeter is approximately:
t = 73.68 s
So, the spider would take about 74 seconds to walk around the perimeter of the room.
Final answer:
To determine the time for a spider to walk around a 3 m by 4 m room, calculate the perimeter (14 m), convert it to centimeters (1400 cm), and divide by the spider's speed (19 cm/s), resulting in approximately 73.68 seconds.
Explanation:
To calculate the time it would take for a spider to walk around the perimeter of a 3 m by 4 m room, first, find the perimeter of the room by adding the lengths of all the sides:
Perimeter = 2 × (3 m) + 2 × (4 m) = 6 m + 8 m = 14 m.Next, since the spider walks 19 cm each second, convert the perimeter from meters to centimeters because the units need to match.
Perimeter in centimeters = 14 m × 100 cm/m = 1400 cm.Now, divide the total perimeter by the spider's speed to find the time it takes:
Time = Perimeter / SpeedTime = 1400 cm / 19 cm/sTime ≈ 73.68 secondsTherefore, it would take approximately 73.68 seconds for the spider to walk around the perimeter of the room.

If a stereo is sold for $59.99 and Karen pays $64.19 for it when she checks out, what is the sales tax in the area
The sales tax in the area where Karen bought the stereo is $4.20. This was calculated by subtracting the original price of the stereo ($59.99) from the total price paid ($64.19).
Explanation:To find the sales tax in this scenario, we need to subtract the original price of the stereo, which is $59.99, from the total price that Karen paid, which is $64.19. The difference will represent the sales tax that Karen had to pay at the checkout.
So we calculate: $64.19 - $59.99 = $4.20
Therefore, the sales tax that Karen paid for the stereo is $4.20.

A film set designer is using white and colored tiles in a pattern to create paths of different lengths. If x is the length of the path in feet, the number of colored tiles needed to make it is calculated using the rule
(4x2y3)(3x2y2)
where y represents the number of white tiles.
Which simplified expression represents the number of colored tiles used for a path of length x feet?
7x4y5
7x4y6
12x4y5
12x4y6
The simplified algebraic expression for the number of colored tiles used for a path(4x^2y^3)(3x^2y^2), is 12x^4y^5. Hence the correct option is 3,
Given the algebraic rule for determining the number of colored tiles ((4x2y3)(3x2y2)), we simplify this expression by multiplying the coefficients and then by adding the exponents for x and y (since they are the same base).
Multiply the coefficients: 4 x 3 = 12
Add the exponents for x: 2 + 2 = 4 (since x2 x x2 = x2+2)
Add the exponents for y: 3 + 2 = 5 (since y3 x y2 = y3+2)
