Answer:
The quotient of the division will become a factor in a multiplication fact.
Step-by-step explanation:
In division there is a relationship between the dividend, divisor, quotient and remainder. The number which we divide is referred to as the dividend. The number by which we divide is called the divisor. The result obtained is known as the quotient. The number left over is called the remainder.
The dividend, divisor, quotient and remainder will help us to verify the answer of division. Add remainder (if there is any) with the product of divisor and quotient. The sum we get should be equal to the dividend.
The quotient of the division will become a factor in a multiplication fact.
For instance,
18 ÷ 3= 6
Where 3 is the divisor, 6 the quotient and 18 the dividend
3 × 6= 18
The quotient of the division 6 is a factor in the multiplication.
The scale of Miguel's dollhouse is 1in.=2 2/7ft. If the pants of the military uniform of the father in the dollhouse are 1 2/5 inches long, how long would the pants be in real life?
Answer:
3 1/5 ft
Step-by-step explanation:
We can set up a proportion:
[tex]\frac{1}{2\frac{2}{7} } =\frac{1\frac{2}{5} }{x}[/tex] , where x is how long the pants are in real life
Cross multiply:
x = (2 2/7) * (1 2/5)
It's easier if we have improper fractions, so convert the mixed numbers into improper fractions:
2 2/7 = 16/7
1 2/5 = 7/5
Now, put these back in:
x = (16/7) * (7/5) = 16/5 = 3 1/5
Thus, in real life, the pants would be 3 1/5 ft long.
Hope this helps!
Answer:
3⅕ ft
Step-by-step explanation:
1 in --> 2 2/7 ft
2 2/7 = 16/7
1 2/5 in = 7/5 in
7/5 × 16/7 = 16/5 ft
3 1/5 ft

A shipping container in the shape of a rectangular solid must have a volume of 84 cubic meters. The client tells the manufacturer that, because of the contents, the length of the container must be one meter longer than the width, and the height must be one meter greater than twice the width. What should the dimensions of the container be?
Answer:
The Length , width and height of solid are 4 feet , 3 feet and 7 feet respectively.
Step-by-step explanation:
Let the width of rectangular solid be x
We are given that the length of the container must be one meter longer than the width
So, Length of solid = x+1
We are also given that height must be one meter greater than twice the width
So, Height of solid = 2x+1
So, Volume of solid = [tex]Length \times Width \times height[/tex]
Volume of solid = [tex](x+1) \times x \times (2x+1)[/tex]
Volume of solid =[tex](x^2+x)(2x+1)[/tex]
Volume of solid =[tex]2x^3+x^2+2x^2+x=2x^3+3x^2+x[/tex]
We are given that a rectangular solid must have a volume of 84 cubic meters
So, [tex]2x^3+3x^2+x=84\\2x^3+3x^2+x-84=0\\(x-3)(2x^2+9x-28)=0\\[/tex]
On equating
x-3=0
x=3
So, Length of solid = x+1=3+1 = 4 feet
Height of solid = 2x+1 =2(3)+1=7 feet
Width of solid = 3 feet
Hence The Length , width and height of solid are 4 feet , 3 feet and 7 feet respectively.
The volume of a rectangular solid shipping container = 84 cubic meters
The width of the container = 3m
The length of the container = (x + 1) = (3+1) = 4m
The height of the container = (2x + 1) = (2 x 3 + 1) = 7m
Given:
The volume of a rectangular solid shipping container = 84 cubic meters
Let: The width of the container be x
The length of the container must be one meter longer than the width.
So, The length of the container be (x + 1)
The height must be one meter greater than twice the width.
So, The height of the container be (2x + 1)
To find the dimensions of the container
The Volume of the container = Length x Width x Height
[tex]84=x(x+1)(2x+1)[/tex]
[tex]84=(x^{2} +x)(2x+1)[/tex]
[tex]84=2x^{3} +3x^{2} +x[/tex]
[tex]2x^{3} +3x^{2} +x-84=0\\(x-3)(2x^{2} +9x+28)=0\\x-3=0\\x=3[/tex]
So, The width of the container = 3m
The length of the container = (x + 1) = (3+1) = 4m
The height of the container = (2x + 1) = (2 x 3 + 1) = 7m

Carlo rode his bike from his house to his friend Kevin’s house from there he rode to a video game store then he Road 3.2 km from the video game store back to his house that it was in the grid so the path Carlo trouble how many kilometers deCarlo ride his bike
Answer: 13.7
Step-by-step explanation:
The total distance Carlo travelled form his house to Kelvin's house to the game store and back to his house is 13.7 km.
How to calculate distance from the graph?Using the distance formula, we can caulate the distance he rode from his house to Kelvin's house and then to the video game store.
Therefore,
d = √(y₂ - y₁)²+(x₂- x₁)²
Hence,
(0, 0)(2.5, 6)
Distance from his house to Kelvin's house = √(6- 0)²+(2.5 - 0)²
Distance from his house to Kelvin's house = √36 + 6.25 = 6.5 km
Therefore,
(2.5, 6)(2.5, 2)
Distance from Kelvin's house to game store = √(2- 6)²+(2-5 - 2.5)²
Distance from Kelvin's house to game store = √16 = 4 km
Hence,
Total distance travelled = 6.5 + 4 + 3.2 = 13.7 km

The equation of the line that passes through the point (6, -5) and has a slope of -3/2 is y = -3/2x + 4.
Explanation:To find the equation of the line, we can use the point-slope form of a linear equation, which is given by y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope. In this case, the point is (6, -5) and the slope is -3/2. Plugging these values into the equation, we get y - (-5) = -3/2(x - 6), which simplifies to y + 5 = -3/2(x - 6).
Expanding the equation further, we get y + 5 = -3/2x + 9. To isolate y, we can subtract 5 from both sides of the equation, resulting in y = -3/2x + 4. Therefore, the equation of the line that passes through the point (6, -5) and has a slope of -3/2 is y = -3/2x + 4.

Find the Perimeter of the figure below, composed of a rectangle and two semicircles. Round to the nearest tenths place.
9514 1404 393
Answer:
43.1
Step-by-step explanation:
The perimeter is the sum of the lengths of the two straight edges, each of which is 9 units long, and the circumference of the full circle of diameter 8 units. The circumference is pi times the diameter.
P = 2(9) +8π = 18 +25.13
P ≈ 43.1 . . . units
The perimeter of the combination of a rectangle and two semicircles is found by adding the straight sides of the rectangle and the circumference of the resulting full circle formed by the semicircles. In this case, it's 43.1 units.
To find the perimeter of the combined shape consisting of a rectangle and two semicircles, we need to consider the lengths of the straight parts as well as the circumference of the circles. The perimeter is the sum of the lengths of the straight sides of the rectangle, each of which is 9 units long, and the circumference of the full circle with a diameter of 8 units.
Using the formula for the circumference of a circle (C = πd) where d is the diameter, the circumference of the full circle would be 8π. So, the total perimeter of the shape is:
P = 2*(9) + 8π
That gives us:
P = 18 + 25.13 approximately
So, P ≈ 43.1. . . units

John is icing 30 cupcakes. He spreads mint icing on 1/5 of the cupcakes and chocolate icing on 1/2 of the remaining cupcakes. How many cupcakes will get chocolate frosting?
Answer: 12 cupcakes will get chocolate frosting
Step-by-step explanation: John started with 30 cupcakes and spresd mint icing on 1/5 of these. That means he did the following
Mint icing = 30 x 1/5
Mint icing = 6
That leaves him with a total of 30 minus 6 cupcakes which equals 24 cupcakes.
Next he spreads chocolate icing on half of the remaining, that is half of 24. That means he did the following;
Chocolate icing = 24 x 1/2
Chocolate icing = 12
Therefore 12 cupcakes will get chocolate frosting

margot used 1/2 pounds of turkey to make 2/3 liters of turkey chill. If margots recipe is for 1 liter of turkey chill,how many pounds of turkey will she need to make 4 times the recipe
Answer:
2 pounds of turkey?
Step-by-step explanation:
Margot will therefore need 3 pounds of turkey to make 4 liters of her turkey chili.
To find out how many pounds of turkey Margot will need to make 4 times her turkey chili recipe for 1 liter, we first identify the amount needed for 1 liter based on the given ratio, and then multiply that amount by 4.
Margot uses 1/2 pounds of turkey for 2/3 liters of turkey chili. If we need to find out the amount for 1 liter, we can set up a proportion:
1/2 pounds turkey / (2/3 liters) = x pounds turkey / 1 liter
We cross multiply to solve for x:
(1/2) * 1 = x * (2/3)
Now we solve for x:
x = (1/2) * (3/2)
x = 3/4 pounds of turkey for 1 liter of chili
For 4 liters of chili (4 times the recipe), we would multiply:
4 * (3/4 pounds) = 3 pounds of turkey
Explain how to rewrite the equation -2x - 6y = 18 in slope-intercept form.
Answer:
y = -1/3x -3
Step-by-step explanation:
-2x - 6y = 18
We want to solve for y since the slope intercept form is y =mx+b where m is the slope and b is the y intercept
Add 2x to each side
-2x-6y +2x = 2x+18
-6y = 2x+18
Divide each side by -6
-6y/-6 = 2x/-6 + 18/-6
y = -1/3x -3
This is in slope intercept form with the slope -1/3 and the y intercept -3
Answer:
[tex]y = - \frac{x }{ 3} - 3[/tex]
Step-by-step explanation:
-2x - y = 18
Add 2x to both sides.
-6y = 2x + 18
divide both sides by -6.
[tex]y = \frac{2x + 18}{ - 6} [/tex]
divide 2x + 18 by 6
[tex]y = - \frac{x }{ 3} - 3[/tex]

Lena‘s observed that in the last 12 issues of rise over run weekly 384o out of950 pages contain an advertisement what is the probability that the next page she turns to will contain an advertisement
Answer:
Probability thay the next page she turns to will have an advert = 0.4042
Step-by-step explanation:
In the last 12 issues of the magazine, 384 out of 950 pages contain an advertisement.
We now need to find the probability that the next page has an advertisement.
Probability of an event
= n(of that event) ÷ n(total sample spaces)
n(of the event of an advert) = number of pages with adverts in those issues = 384
n(total sample spaces) = total number of pages = 950
Probability that the next page or any page at all will have an advert = (384/950) = 0.4042

You are making an open box from a rectangular sheet of cardboard by cutting squares of equal length from each corner and folding up the sides. The dimensions of the sheet of cardboard are 15 inches by 12 inches. Write a polynomial that represents the total volume of the open box.
Answer:
[tex]V(x) = 4x^3 - 54x^2 + 180x[/tex]
Step-by-step explanation:
We are given the following in the question:
A rectangular piece of cardboard of side 15 inches by 12 inches is cut in such that a square is cut from each corner.
Let x be the side of this square cut. When it was folded to make the box.
The height of box =
[tex]x\text{ inches}[/tex]
The length becomes
[tex](15-2x)\text{ inches}[/tex]
The width becomes
[tex](12-2x)\text{ inches}[/tex]
Volume of box =
[tex]V =l\times w\times h[/tex]
Putting values, we get
[tex]V(x) = (15-2x)(12-2x)x\\V(x) = (180-30x-24x+4x^2)(x)\\V(x) = (4x^2 - 54x + 180)(x)\\V(x) = 4x^3 - 54x^2 + 180x[/tex]
is the required polynomial for volume of box formed.
