what is this area? marking brainliest
Answer:
57in^2
Step-by-step explanation:
Divide the shape into 2 recatngles.
Imagine a line cuts away a rectangle of length 12in by width 4in. from a square of length (12-9)in. and width (7-4)in
This gives you 2 different shapes
Find their area
Rectangle one has an area of = 12in x 4in = 48in^2
Square has an area of = (12-9) in x (7-4) in = 3x 3 inch = 9in.^2
Find their sum to find the area of the whole compound shape:
48+9 = 57in^2

¿Qué altura tiene un poste que proyecta una sombra de 21 metros, al mismo tiempo que una persona de 1.75 metros de estatura lo observa y proyecta una sombra de 1.35 metros?
Respuesta:
27,22 metros
Explicación paso a paso:
Dado :
Sombra del poste = 21 metros
Altura de la persona = 1,75 metros
Sombra de la persona = 1,35 metros
Altura del poste =?
Usando la relación:
Altura de la persona / sombra de la persona = altura del poste / sombra del poste
1,75 / 1,35 = x / 21
Cruz multiplicar
1,35 * x = 1,75 * 21
x = (1,75 * 21) / 1,35
x = 27,22

Cade and Tyce both tried to find the missing side of the right triangle.
A right triangle is shown. The legs are labeled 6 and 9. A right angle is labeled in between them.
Cade's Work Tyce's Work
a2 + b2 = c2 a2 + b2 = c2
62 + b2 = 92 62 + 92 = c2
36 + b2 = 81 36 + 81 = c2
b2 = 45 117 = c2
Square root b squared equals square root 45. Square root 117 equals c squared.
b ≈ 6.71 10.82 ≈ c
Is either of them correct? Explain your reasoning.
Answer: a2 + b2 = c2 a2 + b2 = c2 is correct
Step-by-step explanation:
reason being:
if a2 and b2 are in the equation that would make c2 a2 rational and when the number is rational thats automatically easy to know the area and square root and thats the key! the questions states the spuare root and area which makes it all easy to know that the correct one is a2 + b2 = c2 a2 + b2 = c2.
(Hopes this helps)
Step-by-step explanation:
Answer:
Tyce is correct because you are finding the hyphenous and not the missing side.
Step-by-step explanation:
I also did the work to double check and I got the same answer as Tyce.

Solve the system using elimination.
y=-x-3
y=x2-15
Answer:
X=4, y=-7
Step-by-step explanation:
To use elimination method, you want to cancel x or y when adding the equations together. So let’s multiply the first equation by -2
2(y)=2(-x-3)
2y=-2x-6
——————
add above equation 2y=-2x-6
to second equation Y=2x-15
add together. 3y=-21
Y=-7
—————————————-
solve for x by substituting y value (7) into either equation
y=-x-3
-7=-x-3
-4=-x
4=x
Hailey is designing a new board game, and is trying to figure out all the possible
outcomes. How many different possible outcomes are there if she rolls a fair die in
the shape of a pyramid that has four sides labeled 1 to 4 and spins a spinner with four
equal-sized sections labeled Red, Green, Blue, Orange?
Given:
Numbers on die = 1, 2, 3, 4
Colors on board = Red, Green, Blue, Orange (equal sized sections)
To find:
The number of different possible outcomes are there if she rolls a fair die in the board.
Solution:
According to the given information,
The total possibilities for numbers = 4
Total possibilities for colors = 4
Total possibilities = Possibilities for number × Possibilities for colors
= [tex]4\times 4[/tex]
= [tex]16[/tex]
So, total 16 possible outcomes are there if she rolls a fair die in the board.
Let Red=R, Green=G, Blue=B, Orange=O, then list of total possible outcomes is:
{1R,1G,1B,1O,2R,2G,2B,2O,3R,3G,3B,3O,4R,4G,4B,4O}
Therefore, the total possible outcomes are 16 and the lies of outcomes is {1R,1G,1B,1O,2R,2G,2B,2O,3R,3G,3B,3O,4R,4G,4B,4O}.
Answer: 8
Step-by-step explanation:
i saw one like the answser it said do 4 x 4 and got 16 then i answer it and got it wrong so i did 4 plus 4
A 1200 kg car and a 2400 kg car are lifted to the same height at a constant speed in a auto service station. Lifting the more massive car requires ____ work.
to be honest with you, I dont know
The work required to lift the massive car of 2400 kg is more than lifting the car with 120 kg
What is Work?Work is defined as the energy that is applied to or removed from an object by applying force along a displacement. For a constant force acting in the same direction as the motion, the work is defined as the product of the force's magnitude and the distance traveled. The dimensions of work is
ML²T⁻² and the SI unit of work is Joule
Work = Force x Distance
The SI unit for work is the joule (J), or newton meter ( Nm ). One joule equals the amount of work that is done when 1 N of force moves an object over a distance of 1 m
Given data ,
Let the work required to move the 2400kg car be W₁
Let the work required to move the 1200kg car be W₂
Now , the force in moving the 2400 kg car = F₁
The value of F₁ = 2400 ( a )
And , the force in moving the 1200 kg car = F₂
The value of F₂ = 1200 ( a )
where a is the acceleration
Let the distance moved be height H
Now , the work W₁ = Force x Distance
Substituting the values in the equation , we get
W₁ = 2400 ( a ) H
And , W₂ = 1200 ( a ) H
Now , W₁ > W₂
Hence , the work required to move 2400 kg car is greater

Find the volume of the figure
Answer:
A = 189.25
Step-by-step explanation:
A = πr²
15 x 10 = 150
5 x 5 x 3.14 = 78.5
78/2 = 39.25
You divide by 2 because it's half of a circle.
150 + 39.25 = 189.25

please answer this question i will give you brainliest!!!!
Answer:
your answer will be 25 .....ok
Answer:
x = 25
Step-by-step explanation:
Given y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 3 when x = 15
3 = 15k ( divide both sides by 15 )
[tex]\frac{3}{15}[/tex] = k, that is k = [tex]\frac{1}{5}[/tex]
y = [tex]\frac{1}{5}[/tex] x ← equation of variation
When y = 5 , then
5 = [tex]\frac{1}{5}[/tex]x ( multiply both sides by 5 to clear the fraction )
25 = x

Mr. Yasin paid a total of 9.43 to buy three boxes of cereal. If he paid 3.99 for the 1st box and 2.97 for the 2nd box how much did Mr. Yasin pay for third box of cereal?
$4.72, 2.47, 6.96, or 3.54
Answer:
$2.47
Step-by-step explanation:
Pretend if Mr. Yasin didn't pay for the 3rd box, find out how much he had left after paying for the first 2 boxes.
9.43 - 3.99 - 2.97 = 2.47

Tan 0 and Cot O
Answer:
Step-by-step explanation:
we can say the angle is also +45° going in the clock wise direction. so take Tan(45)= 1
Cot(45) = 1
b/c Tan(45) = Sin(45) /Cos(45) = ([tex]\sqrt{2}[/tex]/2) / ([tex]\sqrt{2}[/tex]/2) ofc that's just 1
b/c Cot(45) = Cos(45) / Sin(45) , which is the same as above 1

Find S7of the sum of the geometric series.a1=−4374,a7=−6,r=1/3
Group of answer choices
A. −6568
B. −6583
C. −6563
D. −6534
Answer:
The sum of the first 7 terms in the geometric sequence is -6558
Step-by-step explanation:
s7 refers to the sum of the first 7 terms of the geometric sequence
To calculate the sum of terms, we use the sum of terms formula
We have this generally given as;
Sn = a(1-r^n)/(1-r)
a refers to the first term, given as a1 which is -4374
r is the common ratio which is 1/3
n is the number of terms, which is 7
substituting these values;
s7 = -4374(1-(1/3)^7)/(1-1/3)
s7 = -4374(1-(1/3)^7)/2/3
s7 = (3 * -4374)/2 * (1- (1/3)^7
s7 = -6561 * (1-1/2187)
s7 = -6561 * (2187-1)/2187
= -6561 * 2186/2187
= -6558
