What’s the volume of the following shape?
Answer:
Step-by-step explanation:
It should be 360 Pls mark brainliest
Answer:
180 units^3
Step-by-step explanation:
Formula for the volume of a right triangular prism: V=1/3Ah (A=Area of base triangle, h=height)
BASE TRIANGLE
A= 1/2bh (base•height)
A= 1/2•10•4
A= 40 units^2
VOLUME OF PRISM
V=1/3Ah
V= 1/3•40•18
V= 180 units cubed

Pqr=qps work out the value of qps
Answer:
89°
Step-by-step explanation:
Total inner degree of PQRS = (4-2)*180° = 360°
PST is a straight line : 180°
angle PSR = 180-128
=52°
angle RQP + angle QPS = 360 - 52 - 130 = 178°
Angle PQR = Angle QPS
Angle QPS = 178/2 = 89°

Justin likes to get 7 hours of sleep. He woke up after sleeping for 5 1/3 hour. How many more hours does he need to get the amount of sleep he likes?
Answer:
He needs 1 hour 40 minutes more to get the amount of sleep he likes or 1 2/3 hours
Step-by-step explanation:
Justin likes to get 7 hours of sleep.
He woke up after sleeping for 5 1/3 hour = 5 hours 20 mins
Number of more hours needed to get the amount of sleep he likes= 7 hours - 5 1/3 hours.
1 hour = 60 minutes
1/3 hours = 60/3 = 20 minutes
Hours Minutes
7 00 when we borrow 1 hour we borrow 60 minutes
5 20
1 40
He needs 1 hour 40 minutes more to get the amount of sleep he likes
or 1 2/3 hours
Martika surfs with her friends at Virginia Beach. Her friend, Mark, caught 8 waves out of 20 possible waves to ride in to shore. They plan to stay out in the water for 50 more waves. How many of the 50 waves do you predict Mark will catch?
Answer:
20 waves
Step-by-step explanation:
Out of 50 waves, Mark will catch 20 waves. To find this, first, you have to put it into a ratio.
8 x
--- = -----
20 50
To solve this, you need to multiply 8 x 50, which is 400. Next you need to divide 400 by 20, which is 20 waves.
This means x = 20 waves.

You can transform ⨀T to ⨀T' by translating it and then performing a dilation centered at T'. Find the translation rule and the scale factor of the dilation.
Simplify the scale factor and write it as a proper fraction, improper fraction, or whole number.
Translation: (x,y)↦ (___ ) , (____)
,
Scale factor:
Answer:
(x,y)↦ ( x + 1 ) , ( y + 9 )
scale factor 2
Step-by-step explanation:
Step 1 identify the translation.
To do this we find the center of ⨀T and the center of ⨀T' and find the difference between their x and y values.
The center of ⨀T is at ( -1 , -7 )
The center of ⨀T' is at ( 0 , 2 )
we now find the difference between the x and y values. ( note that you must subtract the x and y values from the preimage from the translated image to get the correct translation. )
For the x values: 0 - ( - 1 ) = + 1
For the y values: 2 - ( -7 ) = + 9
So translation was (x,y)↦ ( x + 1 ) , ( y + 9 )
step 2 Find the scale factor
We can identify the scale factor by dividing the radius of the preimage by the radius of the dilated image.
The radius can be identified by finding the distance between the center and any point on the circle
The radius of the preimage is 3
The radius of the dilated image is 6
So scale factor = 6 / 3 or 2

Answer:
8 = D
9 = D
10 = D
Step-by-step explanation:
For 8, a straight line is 180 degrees, and if PQS is already x+55, then RQS is also x, so it would be 2x +55 = 180
For 9, surface area is just area of the sides of a shape, so (3*15)*2 + (6*3)*2 + (5*6)*2 which equals 30 +36 + 60, which is 126.
For 10, the volume is the width*length*height, so 4*4*11 = 16*11 = 176, and because there are 6 rectangular prisms, 176*6 which is equal to 1056.
call me an i.d.i.o.t all you want but can someone help me understand this please

So supplementary angles are ones that add up to 180degrees and complementary ones add up to 90degrees.
So for the left side, you find what angle is supplementary to the given one. For the angle of 35, another angle of 145 will add up to 180.
The right side want you to find the complementary angles, so for the angle of 18, another angle of 72 will add up to 90.
I always forget supplementary vs complementary, but a little bit of practice will help a lot.

When Victoria goes bowling, her scores are normally distributed with a mean of 130
and a standard deviation of 11. What is the probability that the next game Victoria
bowls, her score will be between 123 and 130, to the nearest thousandth?
Answer:
0.2377 or about a 23.77% chance
Step-by-step explanation:
P(123<X<130) = normalcdf(123,130,130,11) = 0.2377303466 ≈ 0.2377
Therefore, the probability that the next game Victoria bowls, her score will be between 123 and 130 is 0.2377 or about a 23.77% chance

Write y=(1)/(8)x+7 in standard form using integers.
A. 8x – y = 56
B. –x + 8y = 7
C. –x + 8y = 56
D. –x – 8y = 56
Answer:
C. –x + 8y = 56
Step-by-step explanation:
Write in standard form.
x − 8 y = − 56
This is a linear function in the slope - intercept form:
y = m x + b and we need a standard form:
a x + b y = c
y = 1/8 x + 7 / * 8 ( we will multiply both sides of equation by 8 )
8 y = x + 56
- x + 8 y = 56 / * ( - 1 )
x - 8 y = - 56
The equation is y = 1/8x + 7
Standard form equation is Ax + By = C, where A > = 0.
First eliminate the fractions by multiplying the equation by 8
8y = x + 56
Subtract x from each side
-x + 8y = 56
SInce x coeficient can't be negative multiply the equation by negative one.
x - 8y = -56
simplify 2/3(6x−1/6)+3x
Answer:
7x - 1/9
Step-by-step explanation:
2/3 (6x - 1/6) + 3x
12x/3 - 2/18 + 3x
4x - 1/9 + 3x
7x - 1/9
After simplifying, the value of expression is,
⇒ 7x - 1/9
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The expression is,
⇒ 2/3 (6x - 1/6) + 3x
Now, We can solve the expression as;
⇒ 2/3 (6x - 1/6) + 3x
⇒ 2/3 × 6x - 2/3 × 1/6 + 3x
⇒ 4x - 1/9 + 3x
⇒ 7x - 1/9
