URGENT 50 POINTS WILL MARK BRAINLIEST HELP Mary plans to put carpeting in her house.
The floor plan shows the part of her
house that will be carpeted. How many
square feet of carpet does she need?
Answer:
225 ft^2
please give branliest if you do so please
Step-by-step explanation:
(12*10)+(5*5)+(8*10)
120+25+50
225
Hey there! I'm happy to help!
Let's think of this as one giant rectangle. We see that a little bit is cut out, but we will ignore that for now.
The width of this rectangle is 10 ft.
The length is 12+5+8 feet which is 25 feet. (we have the lengths of 12 and 8 on the top and the length of 5 is below, but it matches the missing length at the top).
We multiply the width by the length to find the area of this huge rectangle.
10*25=250
Now, we need to cut out that square that isn't actually part of the room. We see that it's dimensions are 5 ft by 5 ft, so 25 ft. All we have to do is subtract this from the huge rectangle we calculated.
250-25=225
So, Mary needs 225 square feet of carpet.
Have a wonderful day and keep on learning! :D

Answer:
GI=15
Step-by-step explanation:
GI=HI+GH
GI=12+3= 15
I hope I helped you^_^
Hi! I'm happy to help.
To solve this we need to know what is happening. This line segment was split into two parts by H. GH (part 1) and HI (part 2).
These two parts together equal the total length of the line segment. We learn that GH is 3, and HI is 12.
12+3=15
Now, we know that GI has a length of 15.
I hope this was helpful, keep learning! :D
The line passing through points (5,) and (2,−3) is parallel to a line with a slope of 4/3. What is the value of y?
Answer:
Step-by-step explanation:
Parallel lines have same slope
Slope = [tex]\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]\dfrac{-3-y}{2-5}=\dfrac{4}{3}\\\\\\\dfrac{-3-y}{-3}=\dfrac{4}{3}\\\\\\-3-y=\dfrac{4}{3}*(-3)\\\\\\[/tex]
-3-y = 4*(-1)
-3 - y = -4
- y = - 4 + 3
-y = -1
Divide both sides by (-1)
y = 1

barbara and jeff ate out for dinner the total came to &15.00. they left a 15% tip how much was the tip and the meal together?
Answer:
$17.25
Step-by-step explanation:
The tip is 15% of $15.00, or 0.15 * 15 = $2.25
We add that to the meal's cost, which is $15.00
15.00 + 2.25 = 17.25

. Cathy is playing a game with a set of 52 cards. The cards are different
colors and each show a number.
• The probability of randomly selecting a black card is.
• The probability of randomly selecting a red card is.
If Cathy randomly selects a card, what is the probability that her card is
black OR red?
Answer:
something missing here... is this a regular deck of cards Hearts, spades, clubs , and diamonds ? 1/2 red and 1/2 black ... if so....
then.....
P(black) = .5
P(red) = .5
P(red or black) = 1 (100%)

Find the probability of “landing” in the shaded region of the figures below. Round your answer to the nearest hundredth.
Answer:
#4Area of rectangle:
A = lw = 10*20 = 200 m²Shaded area:
A = 2πr² = 2π(10/2)² = 157.079 m²Probability:
P = 157.079/200 ≈ 0.785 or 78.5%#5Area of bigger circle:
A = πr² = π(20)² = 1256.637 m²Shaded area:
A = π(10² - 5²) = 235.619 m²Probability:
P = 235.619/1256.637 ≈ 0.187 or 18.7%Answer:
4
We know that
Area of rectangle = lb
Area = 10(20)
Area = 200 m²
Shaded region = πr²
=> 2 × 22/7 × (10/2)²
=> 2 × 22/7 × 10/4
=> 157 m²
Probability = 157/200 = 78.5%
5.
Area of the biggest circle = πr²
= 22/7 × (20)²
= 1256.6
Area of shaded region
π(10² - 5²)
π(100 - 25)
3.14(75)
235.6
Probability = 235.6/1256.6 = 18.7%

find the HCF
eg. first expression = 4a -8
=4(a-2)
Answer:
Step-by-step explanation:
ab² + 2a²b + a³ = a(b² + 2ab + a²)
Here variable 'a' is common in all the terms. HCF = a
2) 2ab² = 2 * a * b *b
4a²b = 2 * 2 *a * a * b
6a³ = 2 * 3 * a * a * a
HCF = 2a
2ab² - 4a²b - 6a³ = 2a(b² - 2ab - 3a²)
Please help with answers I need them as soon as possible!
I don’t even know what these are called, please explain what they are and how they work
Step-by-step explanation:
Notice the two horinzontal lines. They are parallel lines as they will never cross each other.
Notice the slant line. That is called a transversal as it crosses through both the parallel lines.
The transversal split the parallel lines into multiple angles.
Vertical AnglesAlternate Interior AnglesAlternate Exterior AnglesCorresponding AnglesLinear Pair AnglesSame Side Consecutive AnglesLook at Angle X and the angle on the upper right. They are vertical angles because they are formed by intersecting lines so they are equal to each other
Look at Angle X and the angle that is on the right of Angle 70, they are alternate interior angles as they are formed by the transversal crossing through the two parallel lines. They are equal to each other. They form a Z if you connect a them.
The upper right angle and bottom left angle are alternate exterior angles. They are formed by the transversal. They are equal to each other. They form a semi circle of you connect them.
The bottom left angle and Angle X are Corresponding Angles. They form a C shape if you connect them. They are formed by the transversal and are congruent to each other.
Angle X and 70 are same side consecutive angles. They are right next to each other on the same side of each other. They are supplementary. which means they form 180 degrees when added.
so using this info,
[tex]x + 70 = 180[/tex]
[tex] x = 110[/tex]
