Problem 8
The box portion of the shed (ignoring the triangular roof) has a volume of:
length*width*height = 10*8*6.5 = 520 cubic feet
The triangular face on the right side has an area of base*height/2 = 8*2.5/2 = 10. Multiply this with the depth of the triangular prism and we get a volume of 10*10 = 100 cubic feet.
The two sub-volumes combine to 520+100 = 620
Answer: 620 cubic feet===========================================================
Problem 9
Let's find the area of the base
area = side*side = (4.2)*(4.2) = 17.64 sq inches
Then we plug that into the formula below, along with the height of the pyramid
V = volume of a pyramid
V = (1/3)*(area of the base)*(height)
V = (1/3)*(17.64)*(5)
V = 29.4
Answer: 29.4 cubic inchesYour teacher made a typo. She or he should have written [tex]\text{in}^3[/tex] instead of [tex]\text{in}^2[/tex]
Answer:
Okay so you basically need to break this shape into sensible pieces. Such as rectangular and triangular prisms.
first let's find the rectangular prisms' volume, we need to multiply 6.5 with 10 and 8.
6.5×10×8 gives us 520
520 is the volume of the rectangular prism (below the shape)
to find the triangular prism's volume follow these steps:
2.5×8×10×1/2 which gives us 100
now we need to take the sum of these
100+520=620
the answer is C good luck!
Julia has 42 m of fencing to build a three-sided fence around a rectangular plot of land that sits on a riverbank. (The fourth side of the enclosure would be the river.) The area of the land is 180 square meters. List each set of possible dimensions (length and width) of the field.
The list of the set of dimension for fencing the building around a rectangular plot of land is 10.5 meters and 21 meters.
Area of a rectanglearea of rectangle = lw
where
l = lengthw = widthTherefore,
perimeter = 2w+ l
42 = 2w + l
l = 42 - 2w
Hence,
area = w(42 - 2w)
180 = 42w - 2w²
-2w² + 42w - 180 = 0
-w² + 21w - 90 = 0
The dimension w can be found as follows;
w = - b / 2a
where
a = -1b = 21w = - 21 / 2 × -1
w = 10.5 meters
Then,
l = 42 - 2w
l = 42 - 2(10.5)
l = 21 meters
Therefore, the dimensions are 10.5 meters and 21 meters.

1. Are the side lengths congruent?
2. Are the opposite sides parallel?
3. Are the adjacent sides perpendicular?
Answer:
1:If three pairs of sides of two triangles are equal in length, then the triangles are congruent. ASA (angle-side-angle): If two pairs of angles of two triangles are equal in measurement, and the included sides are equal in length, then the triangles are congruent. 2:All sides are equal in length. Diagonals bisect each other at a 90-degree angle. The sum of any two adjacent interior angles is 180 degrees. Opposite sides are equal and parallel to each other.3:Each pair of opposite sides is parallel, and adjacent sides are perpendicular. This means that every angle in a rectangle is a right (90∘) angle.

Assume that the salaries of computer programmers are normally distributed, with a mean of $66,000 and a standard deviation of $14,000.
If four programmers are selected at random, find the probability that they have a mean salary between $40,000 and $50,000.
a) 0.52
b) 0.09
c) 0.26
d) 0.01
The probability that they have a mean salary between $40,000 and $50,000 is 0.01.
What is Z- score test?A z-test is a statistical test to determine whether two population means are different when the variances are known and the sample size is large.
The z-score for 40,000 is
= (40,000 - 66000) / (14,000 / √4)
= -26000/7000
= -3.714, P- value is 0.000102
The z-score for 50,000
= (50,000 - 66,000) / (14,000 / √4)
=-2.285, P- value is 0.0111564
P(40,000 < x < 50,000) = P( -3.714< z < -2.285)
So,
= P(50,000)-P(40,000)
= 0.0111564-0.000102
=0.011
Hence, the probability that they have a mean salary between $40,000 and $50,000 is 0.01.

Answer:
64
Step-by-step explanation:
16/10=1.6 and 1.6x40=64
Answer: y = 64
Step-by-step explanation:
[tex]$$Given, \\$y$ is directly proportional to $x$ \\$\Rightarrow y \propto x$ (Note: ' $\alpha$ ' be proportion/various sign) \\$\Rightarrow y=k x$ ( $k$ be the constant) \\$\therefore y=k x-$ (1)[/tex]
[tex]$$Given $y=40$ when $x=10$.So, substitute $y=40 \ \& \ x=10$ in (1) we get,$$\begin{aligned}&\Rightarrow 40=k(10) \\&\Rightarrow 10 k=40 \\&\Rightarrow k=\frac{40}{10} \text { (divide '10' both sides) } \\&\Rightarrow k=4\end{aligned}$$[/tex]
