the area of a small square is 25 square units what is the exact length in units of a single of a large square
Answer:
5
Step-by-step explanation:
The area of any quadrilateral can be determined by multiplying the length of its base by its height. Since we know the shape here is square, we know that all sides are of equal length. From this we can work backwards by taking the square root of the area to find the length of one side.
HELP DUE SOON!!!Elise says, "If you subtract 14 from my number and multiply the difference by - 4, the result is
- 100." What is Elise's number?
Elise's number is
Answer:
39
Step-by-step explanation:
If you subtract 14 from my number and multiply the difference by -4, you should get -100.
You need to setup the equation that is being given to you.
Subtract 14 from my number.
x - 14
Multiply the difference by -4
(x-14) * -4
You should get -100.
(x-14) * -4 = -100
Solve for x
(Elise's number is X, the missing number).
[tex]-4(x-14) = -100\\-4x+56 = -100\\-4x=-156\\x=39[/tex]
Elise's number is 39.
Kristopher has a coupon for $10 off any item at his favorite electronics shop. If he plans to use the coupon to purchase and item that costs $80, by what percentage will the price be decreased before tax?
Answer:
12.5%
Step-by-step explanation:
Kristopher has a coupon for $10 off any item at his favorite electronics shop. If he plans to use the coupon to purchase and item that costs $80, by what percentage will the price be decreased before tax?
The formula for Percentage Decrease =
Decrease in price/ Initial price × 100
Decrease in price = $10
Initial price = $80
Hence:
$10/$80 × 100
= 12.5%
Hence, the percentage the price will be decreased by before tax is 12.5%

What is ratio?"It is an ordered pair of numbers a and b, written [tex]\frac{a}{b}[/tex] where b does not equal 0."
What is proportion?"When two ratios are equal then they are said to be in proportion."
For given question,
A small triangle has a base of 1.7 feet and height of 9.3 feet.
A larger triangle has a base of 3.5 feet and height of x feet.
Since it is the enlargement of the triangle, the sides of both the triangle must be in proportion.
[tex]\Rightarrow \frac{1.7}{3.5}= \frac{9.3}{x}\\\\\ \Rightarrow 1.7\times x=3.5\times 9.3\\\\ \Rightarrow 1.7\times x=32.55\\\\ \Rightarrow x=19.14[/tex]
Therefore, the value of the x is 19.1 feet.

Fred's Fruit Stand has 252 pounds of fruit and sells 2 7/8 pounds per hour. Gary's grocery Store has 285 pounds of fruit and sells 3 1/3 pounds per hour. How many hours until they have the same amount of fruit left?
Answer:
72.1 hours
Step-by-step explanation:
Let the number of hours be represented as: x
Fred's Fruit Stand has 252 pounds of fruit and sells 2 7/8 pounds per hour.
Convert 2 7/8 pounds to decimal = 2.875pounds
Hence:
252 - 2.875x
Gary's grocery Store has 285 pounds of fruit and sells 3 1/3 pounds per hour.
Convert 3 1/3 pounds to decimal = 3.333 pounds
Hence:
285 - 3.333x
How many hours until they have the same amount of fruit left?
This calculated by equating both equation together
252 - 2.875x = 285 - 3.333x
Collect like terms
-2.875x + 3.333x = 285 - 252
0.458x = 33
x = 33 / 0.458
x = 72.052401747 hours
x ≈ 72.1 hours
They would have the same amount of fruit left after 72.1 hours

Find the measure of each side indicated. Round to the nearest tenth.
Answer:
Step-by-step explanation:
to find x we can use tangent function
tan 31= x/9
0.60=x/9
x=0.60*9=5.4 choice B
The measure of x side.
We have given a right angle triangle whose angle A=31 degrees and two sides that is x and 9.
We have to determine the value of x.
Therefore we use here the trigonometric ratio
What is the tan ratio?[tex]tan\theta=\frac{opposite side}{adjacent side}[/tex]
Therefore we get
tan 31= x/9
tan(31)=0.60
0.60=x/9
Isolate the x
x=0.60*9
x=5.4

In the figure above, rectangle V'W'X'Y' is a dilation of rectangle VWXY. What is the scale factor of the dilation?
A. 0.25
B. 2
C. 343 fourths
D. 14
Answer:
D. [tex] \frac{1}{4} [/tex]
Step-by-step explanation:
Given that rectangle V'W'X'Y' is a dilation of rectangle VWXY, this means that the dimensions of rectangle VWXY was reduced by to get the dimensions of V'W'X'Y'.
Therefore, the ratio of any segment of V'W'X'Y', to a corresponding segment of VWXY would be equal to the scale factor.
W'X' = 5
WX = 20
Therefore:
Scale factor = [tex] \frac{5}{20} = \frac{1}{4} [/tex].
A scale factor that is a fraction tells us that the original figure reduced in size resulting into another new figure whose sides are of proportional lengths to the original figure.
In other words, the original figure was compressed go form a new figure.
