What is the total surface area??Please help me I’m so confused i have a test tomorrow
Answer:
216 :)
Step-by-step explanation:
There are five sides in total. To find the total surface area we have to find the area of each side.
Let's start off easy with the rectangle at the base. The width and length are 7 and 6, which gives us an area of 42.
The rectangle with dimensions of 8 as the length and 7 as the width gives us an area of 56.
The rectangle with a length of 10 and a width of 7 gives us 70 as an area.
The two triangles are congruent, so all we have to do is find the area of one and multiply it by two. The formula for an area of a triangle is 1/2(bxh)-or the two legs multiplied by each other and then divided by 2. The length of one of the legs is 8, and the other is 6. That gives us 48, which we will then divide by 2 to give us a total area of 24. Now we have to multiply that by two because there are two triangle sides on this figure and they are congruent. That gives us a product of 48.
Now we add up all the areas of each side:
42 + 56 + 70 + 48 = 216
Harper has a mask collection of 400 masks. She keeps 21% of the masks on her wall. How many masks does she keep on her wall?
Answer:
84
Explanation:
400 × 21%
= 400 ÷ 100 x 21 (because 21% = 21/100)
= 84

Given right triangle HJK, which of the
following ratios is equivalent to cosH?
Answer:
cosH = JH/KH
Step-by-step explanation:
coa refers to base by hypotenuse
for H,
the base is JH and the hypotenuse is KH.
In the given right angled triangle cos H is equivalent to sin K
What is right angled triangle?A triangle in which one of the interior angles is 90° is called a right triangle
Here,
Cos H = Adjacent side / Hypotenuse = [tex]\frac{JH}{KH}[/tex]
In the given option
sin K = Opposite side / Hypotenuse[tex]=\frac{JH}{KH}[/tex]
Therefore Cos H is equivalent to the sin K
Hence, sin K is equivalent to the cos H

What is the slope-intercept equation for this
standard form equation?
6x - 3y = 12
Step-by-step explanation:
solve for y
subtract 6x from both sides
6x-6x-3y=12-6x
-3y=12-6x
divide both sides by -3
-3/-3y=(12-6x)/-3
y=2x-4
y=mx+b
m=slope
b=y-intercept
2=slope
-4=y-intercept
Hope that helps :)

Write a function that represents the total cost of your family's outing to the soccer game after x hours.
Answer:
Please attach an image.
f(x) = (cost)x
Answer:
c=s*x
Step-by-step explanation:
C will be the total cost of our family's outing to the soccer game
While x will be the hours
and S will be the soccer game
So s*x will equal the cost
Making c=.

An isosceles triangle has an angle that measures 90 degrees. Which other angles could be in that isosceles triangle? Choose all that apply. (90), (45), (25), or (80)
Answer:
45°
Step-by-step explanation:
90 + 2(45) = 180
90 + 2(25) ≠ 180
90 + 2(80) ≠ 180
90 + 2(90) ≠ 180
identify the zeros of the polynomial function .
Step-by-step explanation:
To start, every term has an

in common, so we can factor that out. Doing this, we get
x
(

+
x
−
42
)
=
0
What I have in blue can be factored by a thought experiment. What two numbers have a sum of
1

. Thus, this business can be factored as
x
(

We can leverage the zero product property here, setting all three terms equal to zero. As our zeroes, we get

6= x−15
What does 'X' equal?
Answer:
x = 21
Step-by-step explanation:
6 = x - 15
x = 6 + 15
x = 21

Write the number in 2 equivalent forms as a fraction, decimal, or percent.0.40
Answer:
2/5 or 40%
Step-by-step explanation:
.40 is 40 hundredths or 40/100
40/100 can be reduced to 20/50 and reduced again to 10/25 and one more time to 2/5
Percentages are fractions out of 100 so 40/100 would be 40%.

A dolphin jumps from the water at initial velocity of 16 feet per second. The equation h= -16t^2+80t models the dolphin's height at any given time, t. what is the maximum height the dolphin jumps?
a) 1 foot
b) 5 feet
c) 96 feet
d) 100 feet
Answer:
d) 100 feet
Step-by-step explanation:
The x value of the vertex (highest point in this case) is found via -b/2a:
-80/-32 = 2.5
Plug 2.5 into the function:
h(2.5) = -16(2.5)² + 80(2.5)
= - 100 + 200 = 100

Sean bought a laptop and a printer. He sold both items for £1,500 getting £1,300 just for the laptop. Sean made a 46% profit on the cost of the printer. What was the cost of the printer? Give your answer to 2 decimal places.
Answer: £137
Step-by-step explanation:
Since Sean sold both items for £1,500 getting £1,300 just for the laptop, the slave price of the printer will be:
= £1500 - £1300
= £200
Since we are informed that Sean made a 46% profit on the cost of the printer, the cost of the printer goes thus:
= £200 /(1 + Profit percent)
= £200 / (1 + 46%)
= £200 / 1.46
= £136.99
= £137 approximately

Find m RS
S
(6x-28)
(4x+ 20)
Answer:
arc RS = 116°
Step-by-step explanation:
Since the 2 chords are congruent then their minor arcs are congruent, that is
SR = TU, substitute values
6x - 28 = 4x + 20 ( subtract 4x from both sides )
2x - 28 = 20 ( add 28 to both sides )
2x = 48 ( divide both sides by 2 )
x = 24
Then
arc RS = 6x - 28 = 6(24) - 28 = 144 - 28 = 116°
