Kerrie is tiling the floor of a kitchen. The kitchen floor measures 11.3 feet by 9.25 feet. She orders enough tiles for 99 square feet. Which statement about the amount of tiles is correct?
a) Kerrie estimated correctly by rounding down. She has enough tile. The exact area is 104.5 square feet.
b) Kerrie estimated correctly by rounding up. She has enough tile. The exact area is 104.5 square feet.
c) Kerrie did not estimate correctly by rounding up. She does not have enough tile. The exact area is 104.5 square feet.
d) Kerrie did not estimate correctly by rounding down. She does not have enough tile. The exact area is 104.5 square feet.
Answer:
a) Kerrie estimated correctly by rounding down. She has enough tile. The exact area is 104.5 square feet.
Step-by-step explanation:
In mathematics we have what is defined as rounding up and rounding down.
Rounding up of numbers is when the number you want to round up is followed by number from 5 to 9(5, 6, 7, 8, 9)
E.g. 2.5 rounded up to the nearest whole number = 3
Rounding down of numbers is when the number you want to round up is followed by number from 1 to 4(1, 2, 3, 4)
E.g. 2.4 rounded down = 2
We are told in the question
Kerrie is tiling the floor of a kitchen. The kitchen floor measures 11.3 feet by 9.25 feet. She orders enough tiles for 99 square feet.
Kitchen floor is rectangular = Area = Length × Width
= 11.3 × 9.25 feet
= 104.525 square feet
We are told that Kerrie ordered for 99 square tiles.
But looking at the decimal, the number after the decimal are between 1 and 4.
Hence, she would be rounding down.
If Kerrie rounds down to the nearest whole number
11.3 feet = 11 feet
9.25 feet = 9 feet
Finding the area = 11 feet × 9 feet
= 99 square feet
Therefore, the correct statement = option a) Kerrie estimated correctly by rounding down. She has enough tile. The exact area is 104.5 square feet.

1. Simplify the expression:
4+36+(10-8)’-3+7
A. 130
B. 100
C. 38
D. 37
Answer:
The answer isn't in the options anyway I'll write it. the answer is 46.
Step-by-step explanation:
According to BODMAS rule - addition should be done first so
4+36= 40 and -3 +7 = 4 so 40+4 ,= 44
then we should do subtracting so, 10-8 = 2
to conclude we should bring the equation to an end so,
44+2 = 46

Which of the following statements must be true about a parallelogram?
Answer:C
Step-by-step explanation:
Answer two questions about Equations A and B:
A. 5x=20
B. X=4
1) How can we get Equation B from Equation A?
Choose 1 answer:
Multiply/divide both sides by the same non-zero constant
Multiply/divide both sides by the same variable expression
Add/subtract the same quantity to/from both sides
Add/subtract a quantity to/from only one side
Multiply/divide both sides by the same non-zero constant. Therefore, option A is the correct answer.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, A) 5x=20 and B) x=4.
Here, 5x=20
Divide both sides by the same non-zero constant 5, we get
5x/5 =20/5
x=4
Therefore, option A is the correct answer.

Solve for x:
-2 (x -4) - 1/2 (3-4x) = -12
Answer:
No solution for xStep-by-step explanation:
-2 (x -4) - 1/2 (3-4x) = -12
×(-2) ×(-2)
4(x - 4) + (3 - 4x) = 24
4x - 16 + 3 - 4x = 24
-13 = 24 <-- it's not true so it's no solution

The Midpoint of UV is M(4, -6). Find V given U(7, -9)
Answer:
(1, -3)Step-by-step explanation:
Given the Midpoint of UV is M(4, -6) and U(7, -9), we are to find the other coordinate V. The formula for calculating the midpoint of two coordinates is expressed as shown;
M(X,Y) = (x1+x2/2, y1+y2/2)
X = x1+x2/2
Y = y1+y2/2
Given (X,Y) = ()4, -6)
U (x1, y1) = (7, -9)
To get x2 and y2, we will substitute the given values into th formula above;
4 = (7+x2)/2
cross multiply
4*2 = 7+x2
8 = 7+x2
x2 = 8-7
x2 = 1
Similarly for y2;
-6 = (-9+y2)/2
cross multiply
-6*2 = -9+y2
-12 = -9+y2
y2 = -12+9
y2 = -3
Hence the other coordinate V(x2, y2) is (1, -3)
. A basketball coach is interested in measuring a player’s vertical jumping ability. While standing
and reaching up, the player’s hand reaches the 4-in. mark on the scale. When jumping, the player
can reach the 19-in. mark. What is the player’s vertical jumping ability?
Answer:
The player's vertical jump ability is 15 inches
Step-by-step explanation:
The mark on the scale which the player's hand can reach while standing = 4-in which is the standing reach
The mark on the scale the player's hand can reach when jumping = 19-in
Therefore, the player's vertical jumping ability is given as the difference between the height the players hand can reach when jumping and the height which the player's hand can when standing,
Which gives;
The player's vertical jump ability = 19 inches - 4 inches = 15 inches
The player's vertical jump ability = 15 inches.

Step-by-step explanation:
65 inches is the diameter of the screen
We have a right triangle for a tv with the side length of 16x and 9x
Using the Pythagorean theorem
a^2 +b^2 = c^2
(16x)^2 + (9x)^2 = 65^2
256x^2+ 81x^2 = 4225
Combine like terms
337x^2 = 4225
Divide each side by 337
x^2 =4225/37
Take the square root of each side
x =65sqrt(337)/337
x =3.54077562
The width is 16 times this
width =56.65240991
height is 9 times this
height = 31.86698058
F(x)=3x-2
Simplify F(2x)-F(x+2)
Answer:
3x - 6
Step-by-step explanation:
To evaluate f(2x) and f(x + 2) substitute x = 2x and x = x + 2 into f(x)
f(2x) = 3(2x) - 2 = 6x - 2
f(x + 2) = 3(x + 2) - 2 = 3x + 6 - 2 = 3x + 4
Thus
f(2x) - f(x + 2)
= 6x - 2 - (3x + 4)
= 6x - 2 - 3x - 4
= 3x - 6

Answer:
Answer: Option B.
Step-by-step explanation:
Hey there!!
Let's simply solve it.
Given,
[tex] \frac{1}{2} x + \frac{1}{4} x = 16[/tex]
Now, take LCM.
[tex] \frac{2x + x}{4} = 16[/tex]
Multiply 16 by 4.
[tex]3x = 16 \times 4[/tex]
or, 3x = 64.
Divide 64 by 3.
[tex]x = \frac{64}{3} [/tex]
x= 21.33
Therefore, your answer is option B.

On a map, 1cm represents 65 km. If two cities are 1950 km apart, how many centimeters apart would they be on this map?
Answer:
30 cm.
Step-by-step explanation:
We can solve this problem by making a proportion:
1 cm/65 km = x cm/1,950 km
By cross-multiplying, we can solve for x:
65x = 1,950
x = 30
