Answer:
A
Step-by-step explanation:
Its a right angle, so you have to use trigonometry.
To find x , you use sin60° = opposite/hypotenuse
opposite = x and hypotenuse = 5 . So,
sin60°= x/ 5
5sin60° = x
put the value into your calculator you ' ll get:
[tex] x = \frac{5 \sqrt{3} }{2} [/tex]
To find y, cos60°= adjacent/hypotenuse
adjacent= y and hypotenuse = 5. So,
cos60°= y/5
5cos60°=y
[tex]y = \frac{5}{2} [/tex]
Hope I was able to help. Good luck!<3

Becca is painting a birdhouse (rectangular prism) that has a height of 13cm, a width of 5 cm, and a length of 8cm. How much paint will she need if she only uses 1 coat? 26 sq. cm 0418 sq. cm 0 208 sq. cm
Answers
Answer:coo
Step-by-step explanation:Cooke.
The amount of paint which will Becca need to paint the birdhouse in 1 coat is 418 cm².
What is surface area?Surface area of any solid or the 3 dimensional body is the area of each faces by which the solid body is enclosed.
The surface area of rectangular prism can be given as,
[tex]SA=2(wl+hl+hw)[/tex]
Here, (w) is the width, (h) is the height and (l) is the length of the prism.
Becca is painting a birdhouse. The shape of the birdhouse is similar to rectangular prism with dimensions as, height of 13cm, a width of 5 cm, and a length of 8cm.
Now Becca wants to paint this house using 1 coat. As this paint has to be cover each surface of the house. Thus the amount of total paint should be equal to the surface area of the house.
Here, the dimensions of house is as, height of 13cm, a width of 5 cm, and a length of 8cm. Therefore the surface area of it is,
[tex]SA=2(5\times8+13\times8+13\times5)\\SA=418\rm cm^2[/tex]
Hence, the amount of paint which will Becca need to paint the birdhouse in 1 coat is 418 cm².

Answers
Answer:
3x³ + x² - 2
Step-by-step explanation:
a) 3(x squared plus 3x cubed - 2)
x squared = x²
3x cubed = 3x³
3(x squared plus 3x cubed - 2)
= 3(x² + 3x³ - 2)
= 3x² + 9x³ - 6
Rearrange according to power
= 9x³ + 3x² - 6
When the expression is divided by 3, it is equivalent to
3x³ + x² - 2

Answer:
x ≈ 7.7
Step-by-step explanation:
Using Pythagoras' identity on the right triangle on the right side
let the third side be y , then
y² + 4² = 10²
y² + 16 = 100 ( subtract 16 from both sides )
y² = 84
Using Pythagoras' identity on the right triangle on the left side
x² + 5² = y²
x² + 25 = 84 ( subtract 25 from both sides )
x² = 59 ( take the square root of both sides )
x = [tex]\sqrt{59}[/tex] ≈ 7.7 ( to the nearest tenth )

question: solve the solution using substitution.
Answers
Answer:
x = -3
y = -8
Step-by-step explanation:
2y = x - 13
3x = y - 1; let y = 3x + 1
substitute to solve for 'x':
2(3x + 1) = x - 13
6x + 2 = x - 13
5x + 2 = -13
5x = -15
x = -3
solve for 'y':
3(-3) = y - 1
-9 = y - 1
-8 = y
Answer:
(-3,-8)
Step-by-step explanation:
Get one of the variables by themself.
3x = y-1
y = 3x+1
Plug that equation into the other one
2(3x+1) = x-13
Distribute the 2 to 3x+1
6x+2 = x-13
Combine like terms
6x+2 = x-13
-x -x
5x+2 = x-13
-2 -2
5x = -15
Divide by 5 on both sides
5x = -15
÷5 ÷5
x = -3
Find y
3(-3) = y-1
-9 = y-1
+1 +1
y = -8

What is Algebraic expression ?
Algebraic expression can be defined as combination of variables and constants. An algebraic expression is a combination of variables, constants, and mathematical operations, such as addition, subtraction, multiplication, division, and exponentiation.
The variables represent unknown or unspecified values that can take on different numerical values, while the constants are specific, fixed values that do not change.
The mathematical operations are used to manipulate the variables and constants and to create different algebraic expressions.
Given expression ,
[tex](-3m^5)(–2m^4)[/tex]
we know that [tex]a^m * a ^n = a ^ (m+n)[/tex]
[tex](-3m^5)(-2m^4) = 6m^(5+4)[/tex]
= [tex]6m^9[/tex]
Therefore, the answer is [tex]6m^9[/tex] in standard form.

74% of 19 year old males are atleast 172 pounds , what percent of the males are not atleast 172 pounds?
Answers
Answer:
The percentage of males are not at least 172 pounds
P(X⁻ ≥ 172) = 0.26
Step-by-step explanation:
Step(i):-
Given that 74% of 19 -year -old males are at least 172 pounds
Let 'X' be a random variable in a binomial distribution
P( X≥172) = 74% = 0.74
we have to find that the percentage of males are not at least 172 pounds
Step(ii):-
The probability of males are not at least 172 pounds
P(X⁻≥172) = 1- P( X≥172)
= 1- 0.74
= 0.26
Final answer:-
The percentage of males are not at least 172 pounds
P(X⁻ ≥ 172) = 0.26

Answers
Answer:
The numbers are 13 , 16
Step-by-step explanation:
First number be x
Second number be y
x - y = -3 --------------------(I)
x = -3 +y
8x + 5y = 184 ---------------(II)
substitute x = -3 + y in equation(I)
8*(-3 + y) + 5y = 184
-24 + 8y + 5y = 184
-24 + 13y = 184
13y = 184 + 24
13y = 208
y = 208/13
y = 16
Plugin y = 16 in (I)
x - 16 = -3
x = -3 +16
x = 13
