[tex]248[/tex]
Step-by-step explanation:
A=2(wl+hl+hw)=2·(10·4+6·4+6·10)=248
Answer:
ok so first you have to multiple 4 and 6 which is 24 times 2 since there is two small rectangles which is 48
then, multiply 10 with 4 which is 40 times 2 since there is two rectangles is 80
then, 6 times 10 which is 60 times 2 since there is two squares which is 120
and lastly, you add 48 with 80 which is 128 plus 120 which is 248

What theorem uses a rotation then reflection
Answers
Hello!
I see this question relates to mathematics in the topic, geometry.
I have personally learned about rotations and reflections, and would like to knowledge you to the best of my abilities based on the question you have asked.
A rotation and reflection are all translations.
Translations move the figure but don't change its size.
A dilate changes the size of the figure by a scale factor.
All of these mentioned are transformations.
I am not sure if there is a theorem that used rotations and reflections, but i do no that rotations and reflections are both translations.
I hope you found this well,
And have a wonderful day.
Thank you for your support,

Answers
Because 5x2=10

Answer:
10+5x
Step-by-step explanation:
The distributive property is where you multiply what's on the outside with ALL the terms on the inside.
Here, you have to multiply 5 by two terms on the inside: 2 and x. 5*2 is 10 and 5*x is 5x. Add them together and your answer is 10+5x (or, 5x+10).

Answer:
The speeds are 88 / 9, 92 / 11, and 96 / 13
Step-by-step explanation:
Since we are already given the equation here, we can plug in the given speeds to find the times. Plugging in 45 will give t = 2 + 350 / 45 which is 2 + 70 / 9. 2 = 18 / 9. We get the time is 88 / 9. Plugging in 55 will give t = 2 + 350 / 55 = 2 + 70 / 11. 2 = 22 / 11. The time is 92 / 11. Plugging in 65 will give t = 2 + 350 / 65 = 2 + 70 / 13. 2 = 26 / 13. The time is 96 / 13.

Math Problem 1: What is the total area of Xavier’s lot?
Use the formula for calculating the area of a trapezoid to help answer your question:
A= a+b2c or front of lot + back of lot/2
Once Bradley has the total area of the lot, he explains to Xavier that the county only allows for 40 percent of any lot to be covered with buildings.
Math Problem 2: What is Xavier’s available lot coverage? (In other words, how big a house can he build?)
Use the formula for calculating percentage to help answer your question:
40/100 = x/Total Area.
Answers
Problem 1:
To find the area you must use the formula A = (b_1 + b_2)h/2, so you do (175 + 185)100/2 which is 360*50 = 18000cm².
A = 18000 cm²
Problem 2:
Just use the shown formula, so it would be 40/100 = x/Area, 40*18000/100 = 40*180 = 7200cm²
Available lot coverage = 7200cm²
The area of the trapezoid is 18000 square units.
The area available for lot coverage is 7200 square units.
What is a trapezoid?A trapezoid is a four-sided shape that has one pair of sides parallel.
We have,
Area of a trapezoid:
= 1/2 ( a + b ) h
a and b are the two parallel sides.
h = height of the trapezium.
We have,
a = 175
b = 185
h = 100
Area of a trapezoid:
= 1/2 x ( 175 + 185 ) x 100
= 1/2 x 360 x 100
= 18000
We will calculate 40% lot coverage of the 18000 area.
40% = 40 / 100
So,
= 40/100 x 18000
= 7200
Thus,
The area of the trapezoid is 18000 square units.
The area available for lot coverage is 7200 square units.

Someone can steal the food lol
The probability of a person randomly selecting a cheesecake, putting it back, and then selecting a cookie is 1/100, 0.01, or 1%.
We have,
To find the probability of selecting a cheesecake, putting it back, and then selecting a cookie, we need to determine the individual probabilities of each event and multiply them together.
The probability of selecting a cheesecake is 1 out of 10, since there is one cheesecake out of 10 options.
Therefore, the probability of selecting a cheesecake is 1/10.
After putting the cheesecake back, the total number of options remains the same, so the probability of selecting a cookie is also 1 out of 10, which is 1/10.
To find the probability of both events happening, we multiply the individual probabilities:
Probability of selecting a cheesecake and then a cookie
= (1/10) * (1/10)
= 1/100
Expressed as a decimal, the probability is 0.01.
To express it as a percentage, we multiply the decimal by 100:
Probability = 0.01 * 100 = 1%
Therefore,
The probability of a person randomly selecting a cheesecake, putting it back, and then selecting a cookie is 1/100, 0.01, or 1%.

we know the Hyp and an angle and we want to know the Adj (BC) so use
