Answer:
Density = 10,490 g/m³
Step-by-step explanation:
Density = mass ÷ volume
here mass = 73,430 g
volume = 7 m³
density = 73,430 ÷ 7
= 10490 g/m³
Density = 10,490 g/m³

In the accompanying diagram, parallelogram ABCD has
vertices A(2, 1), B(8,1), C(11,5), and D(5,5). What is the
area of parallelogram ABCD?
Answer:
The area of the paralellogram is 24 square units.
Step-by-step explanation:
Geometrically speaking, the area of the parallelogram has an equation equivalent to the area formula for a rectangle, that is:
[tex]A = b\cdot h[/tex] (1)
Where:
[tex]A[/tex] - Area.
[tex]b[/tex] - Base.
[tex]h[/tex] - Height.
The base and height of the parallelogram are, respectively:
Base
[tex]b = 8-2[/tex]
[tex]b = 6[/tex]
Height
[tex]h = 5-1[/tex]
[tex]h = 4[/tex]
Then, the area of the parallelogram is:
[tex]A = (6)\cdot (4)[/tex]
[tex]A = 24[/tex]
The area of the paralellogram is 24 square units.

Answer:
-30
Step-by-step explanation:
write the slope-intercept form of the equation of the line trough the given point with the given slope.
trough : (1, -4), slope= -8
A.y=8x+4
B.y=-8x+4
C.y=4x+8
D.y=3x+8
Given:
Point = (1,-4), Slope - 8
Point = (1,5), Slope =1
To find:
The slope-intercept forms of the given lines.
Solution:
The slope intercept form of a line is:
[tex]y=mx+b[/tex]
The point slope form is:
[tex]y-y_1=m(x-x_1)[/tex]
where, m is the slope of the line.
We have, Point = (1,-4), Slope - 8. So, the equation of the line is:
[tex]y-(-4)=-8(x-1)[/tex]
[tex]y+4=-8x+8[/tex]
[tex]y=-8x+8-4[/tex]
[tex]y=-8x+4[/tex]
Therefore, the correct option is B.
We have, Point = (1,5), Slope =1. So, the equation of the line is:
[tex]y-5=1(x-1)[/tex]
[tex]y-5=x-1[/tex]
[tex]y=x-1+5[/tex]
[tex]y=x+4[/tex]
Therefore, the correct option is D.
Find the area of the parallelogram by composing into rectangles or decomposing into triangles or other shapes as needed. 8 yd 6 yd 15 yd
10 yd
Answer:
Below.
Step-by-step explanation:
The area = area of a rectangle on the same base and between the same parallel lines
= (15 + 6) * 8
= 21 * 8
= 168 yd^2.
Answer:
160
Step-by-step explanation:
First, you add 15 + 6 multiplied by 8.
Expression (15 + 6) x 8=?
First, add the expression in the prentice.
15 + 6= 21
Cut out the 10. Why? Because it says make it a triangle. If u did it the other
way it wouldn't make sense.
then multiply 21 and 8
that gives you 160

Calculate the area of a parallelogram with a 4 inch side, a 10 inch side, and 3 inches tall
Answer:

Step-by-step explanation:
Assuming your parallelogram looks like the one in the attached image.
The area of a parallelogram is base x height, [tex]A=bh[/tex].
The base is 10; the height is 3, so A = 10 x 3 = 30.

Step-by-step explanation:
You pay $3 per square foot for carpeting. Which equation can be solved to find the
amount you will pay to cover a triangular section of the floor with a base of 2 yards and
a height of 5 yards?
Answer:
$135
Step-by-step explanation:
Step 1
Conversion
Base = 2 yards
1 yard = 3 feet
2 yards = x
Cross Multiply
x = 2 × 3 feet = 6 feet
Height = 5 yards
1 yard = 3 feet
5 yards = x
Cross Multiply
x = 5 × 3 feet = 15 feet
Step 2
Find the area of the triangle
Area of a triangle = 1/2 × base × height
Base = 6 feet
Height = 15 feet
Area = 1/2 × 6 × 15
= 45 square feet
Step 3
Find the cost of the carpet
1 Square foot = $3
45 square feet = x
Cross Multiply
x = 45 × $3
x = $135
Therefore, the amount you will pay to cover a triangular section of the floor is $135

Sophie invested 5,000 into an account that will increase in value by 2.3% each year. Write a function to model this situation, then find the value of the investment after 15 years
Answer:
$6725
Step-by-step explanation:
Given data
Princiapal= $5000
Rate=2.3%
Time= 15years
The function that will model this situation is given as
A=P(1+rt)
The above function is a simple interest function
Substitute our data we can find the amount A
A=5000(1+0.023*15)
A= 5000(1+0.345)
A=5000(1.345)
A=5000*1.345
A=$6725
Hence the value of the investment after 15 years is $6725

Find the value of each variable. Round to the nearest tenth. How does the measure of angle x compare to the measure of angle z? Justify.
Answer:
z = 47.2°
w = 42.8°
y = 42.8°
x = 47.2°
Step-by-step explanation:
found altitude ('h') first: 6/h = h/7; h = [tex]\sqrt{42}[/tex]
found base by using Pythagorean Theorem:
7² + ([tex]\sqrt{42}[/tex])² = c²
c = [tex]\sqrt{91}[/tex]
found angle z using Rule of Sines:
sin 90 / [tex]\sqrt{91}[/tex] = sin z / 7
arcsin z = 7 / [tex]\sqrt{91}[/tex] = 47.2°
found angle w by adding 90 and 47.2, then subtracting from 180 to get 42.8°
found angle y by subtracting m∡z from 90° to get 42.8°
found angle x by adding 90 and 42.8°, then subtracting from 180

Autumn has 6 ribbons for her hair. Each ribbon is 3 feet long. How many total inches of ribbon
does Autumn have?
Answer:
she has a total of 216 inches of ribbon
Step-by-step explanation:
1 foot is equal to 12 inches.
if she has 3 feet per ribbon, and each foot is 12 inches, then 3 × 12 would be 36, making each ribbon 36 inches.
But, she has 6 pieces of ribbon, so that's 36 inches 6 times. 6 × 36 is 216, so she has a total of 216 inches of ribbon.
finding the distance from (–6, 2) to the origin. Use (0, 0) as (x1, y1). d = StartRoot (x 2 minus x 1) squared + (y 2 minus y 1) squared EndRoot What is the difference of the x-coordinates, (x2–x1)? What is the difference of the y-coordinates, (y2–y1)? What is the distance from (–6, 2) to the origin?
Answer:
2√10
Step-by-step explanation:
Given the coordinates (-6, 2) and (0,0)
We are to find the distance between the coordinates. Using the distance formula;
d = √(x2-x1)²+(y2-y1)²
d = √(0-2)²+(0+6)²
d = √(-2)²+(6)²
d = √4+36
d = √40
d = √4*10
d = 2√10
Hence the required distance is 2√10

Answer:
The length of the side VT is approximately 11.1 feet long.
Step-by-step explanation:
There is a trigonometry law called the law of sines, which states the sine of an angle divided by its opposite side is equivalent to the sine of all the other angles in that right triangle divided by its corresponding opposite side. You can use this law to help you solve for x. By applying the law of sines, you'll get that [tex]\frac{sin(90^{o})}{36} =\frac{sin(18^{o})}{x}[/tex] ⇒ [tex]\frac{36}{sin(90^{o})} = \frac{x}{sin(18^{o})}[/tex] ⇒ [tex]x=\frac{36*sin(18^o)}{sin(90^{o})}[/tex] ⇒ [tex]x=11.1ft.[/tex]

A prism has total surface area of 360 m2 and volume of 60 m². If the length, width,
and height are doubled their original sizes, what will be the new volume?
o 360 m3
o 480 m
o 120 m2
o 1,620 m
Answer:
480
Step-by-step explanation:
I did the test and this is what it said in the review.
The new volume of the prism is 480 m³, option B is correct
What is Three dimensional shape?A three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
The total surface area of the prism is given by:
2lw + 2lh + 2wh = 360
Dividing both sides by 2, we get:
lw + lh + wh = 180
The volume of the prism is given by:
lwh = 60
Multiplying both sides by 8, we get:
8lwh = 480
Substituting 2l, 2w, and 2h for l, w, and h, respectively, we get:
(2l)(2w)(2h) = 8lwh
(2l)(2w)(2h) = 480
Simplifying, we get:
(2l)(2w)(2h) = 8lwh
8lwh = 480
Therefore, the new volume of the prism is 480 m³, option B is correct

hello
the angles make up co-interior so the two would add up to 180º.
so we can set up a basic equation:
3x-10+5x-30=180
add like terms:
8x-40=180
add 40 to both sides:
8x=220
divide by 8
x=27.5º

Dora has three candles, which will burn for 3, 4 and 5 hours, respectively. If she wants to keep two candles burning at all times, what is the greatest number of hours she can burn the candles? (Dora has a clock that she can use to time the candles.)
Answer:
4 hours
Step-by-step explanation:
As she wants to keep two candles burning so after3 hours only 2 candles will remain and after 4 hours only one but till 4 hours 2 candles would be burning that what she wanted so its 4 hours
If Dora burns candles that burn for 4 and 5 hours, they combine to burn for 9 hours.
What are permutation and combination?Combination and permutation are two alternative strategies for organizing elements of a set into subsets in mathematics. The subset's components can be recorded in any order when combined. The components of the subset are stated in a separate order in a permutation.
Dora has three candles that will burn for 3, 4, and 5 hours, respectively.
The combination of the hours of burning,
3 + 4 = 7 hours
4 + 5 = 9 hours
3 + 5 = 8 hours
So the greatest number is 9
Thus, if Dora burns candles that burn for 4 and 5 hours, they combine to burn for 9 hours.
