Volume = base area x tall
base area = π x (1.8in)²
base area = 10.179 in²
Volume = 10.179 in² x 6.7 in
Volume = 68.198 in³
Answerthe volume is 68.198 in³
What is the slope of a line that goes through the points (10, -2) and (5,-5)? m =
Y1-Y2
11-12
Answer:
m = 3/5
Step-by-step explanation:
use the formula so m = -5 - -2 / 5 - 10 , so m = -5+2 / -5
m = -3/-5 so m = 3/5

Answer/Step-by-step explanation:
1.
✔️a = 180 - 110 (consecutive angles are supplementary)
a = 70°
✔️b = a (corresponding angles are congruent)
b = 70°
✔️c = 110° (alternate interior angles are congruent)
2.
✔️a = 180 - 120 (linear pair)
a = 60°
✔️b = a (corresponding angles are congruent)
b = 60°
✔️c = a (alternate interior angles are congruent)
c = 60°
3.
✔️a = 55° (corresponding angles are congruent)
✔️b = 55° (Vertical angles are congruent)
✔️c = 180 - 55 = 125° (linear pair)
4.
✔️a = 115° (corresponding angles are congruent)
✔️b = 180 - a (linear pair)
b = 180 - 115
b = 65°
✔️c = b (vertical angles are congruent)
c = 65°
5.
✔️a = 180 - 25 = 155° (supplementary angles)
✔️b = 25° (corresponding angles)
✔️c = 25° (vertical angles)
6.
✔️a = 180 - 10 = 170° (linear pair)
✔️b = a (corresponding angles are congruent)
b = 170°
✔️c = 10° (corresponding angles are congruent)
Calculate the value of y to the nearest hundredth.
Answer:
y ≈ 9.24
Step-by-step explanation:
Using the cosine ratio in the right triangle.
cos30° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{8}{y}[/tex] ( multiply both sides by y )
y × cos30° = 8 ( divide both sides by cos30° )
y = [tex]\frac{8}{cos30}[/tex] ≈ 9.24 ( to the nearest hundredth )

Length of sandbox (3w + 1) = 9.1 m
Width of sandbox = 2.7 m
Step-by-step explanation:

Each side of a regular hexagon has a length of 2 ft 3 in. Find the perimeter of the regular hexagon
Answer:
gdghdhsxjsjsj
Step-by-step explanation:
jcjcjcjcjjcjcjcjcjc
Answer:
t is a regular hexagon of side 2′. So it can be divided into 6 triangles equal in all respects.The sum of all interior angle of hexagon =(n-2)*180 = (6–2)180 =720 deg. each interior angle =720/6 =120 deg.Side of the triangle divides this angle into two equal halves each = 60 deg.when two base angles of each triangle are 60 and 60 third angle will also become 60 making it as equilateral triangle. N ow the area of hexagon =6*the area of each equilateral triangle of base 2 ft.=6*1/2*2*h. h is the altitude of the triangle=2/2*tan 60 = rt3 =1.732 .NOW area of hexagon =6*1.732 = 10.392 sq.ft

Ashely found 2 boxes of sugar in the kitchen. The green boxe is 1.26 kg and the red box is 1.026 kg. Which box contains more sugar?
Answer:
The green box by 0.234kg of sugar
Step-by-step explanation:
Given data
The green box weight= 1.26 kg
The red box weight= 1.026 kg
comparing the two values
the green box contains 0.234kg more sugar
=1.26-1.026
=0.234kg

help please! ill mark you brainliest!
Answer:
80 degrees
Step-by-step explanation:
angle c=50
this is an isoceles triangle in which both base angles are same
so, angle e=50
now we will use angle sum.property which states that the sum of all the interior angles of a triangle is equal to 180
so, 50+50+angle d=180
100 + angle d = 180
angle d =180-100
angle d = 80 degrees

PLEASEEEE HELP !!!!!!!!!!!!!!!!! Abanoub is using a machine to drill for oil that is 535 feet under the ground. The drill he is using is drilling at a rate of -35 feet per hour. How long did it take him to reach the oil? a 15.28 Hours b - 15.28 Hours c 18,725 Hours d -18,725 Hours
Answer:
a) 15.28 hours
Step-by-step explanation:
535/-35
≈-15.28
but time is always positive so it would take him 15.28 hours
Evaluate the expression when c=6 and d=5.

A box contains fiction and nonfiction books. There are 22 fiction books in the box, which is 55% of the total number of books in the box. What is the total number of books in the box?
thank you for helping
Answer:
So it's either 12.1
Step-by-step explanation:
So you must multiply them to get the answer cause it tells how much fiction books are in there, and It 55% of the total so to find the total you must multiply them.
But if you have a percent you have to make that into a decimal. So 55% will be 55/100 so that's .55, so all you have to do now is multiply them.
Answer: 40 books
Step-by-step explanation:
First divide 22/55 then multiply the product by 100.
22/55= 0.4
0.4*100=40
Hope this helps u Emilee :)

Are linear inequality graphs different from linear equations graphs
Answer:
The only difference between the two equations is that, a linear equation gives a line graph whereas a linear inequality shows the area of the coordinate plane that satisfies the inequality. A linear inequality graph usually uses a borderline to divide the coordinate plane into two regions.

-0.2(x-20)=44-x Please i really need help. and please add an explanation if u want to.
Answer: x = 50
Step-by-step explanation:
-0.2(x - 20) = 44 - x
-0.2x + 4 = 44 - x (distribute the -0.2)
+ x + x
-----------------------------------------------------
0.8x + 4 = 44
- 4 - 4
-------------------------------------------------------
0.8x = 40 (divide by 0.8)
x = 50
what does x represent in the equation 3x+1=10
Answer:
3
Step-by-step explanation:

3x+1-1=10-1
3x=9 divide both sides by three
3x/3=9/3
x=3

Answer:
h = 2.7 m
Step-by-step explanation:
The larger triangle and the smaller triangle are similar so ratios of corresponding sides are equal, that is
[tex]\frac{6}{6+12}[/tex] = [tex]\frac{0.9}{h}[/tex] , that is
[tex]\frac{6}{18}[/tex] = [tex]\frac{0.9}{h}[/tex] ( cross- multiply )
6h = 16.2 ( divide both sides by 6 )
h = 2.7 m
