Answer:
30 degrees.
Step-by-step explanation:
A triangle has 180 degrees. The two base angles are 75 degrees each. The third angle is x
75 + 75 + x = 180 Combine like terms on the left
150 + x = 180 Subtract 150 from both sides.
-150 -150
x = 30
The third angle is 30 degrees.
Here is a right square pyramid. The length of each side of the base is 3 cm. The height of the pyramid is 8 cm. What is the volume of this pyramid?
9514 1404 393
Answer:
24 cm³
Step-by-step explanation:
The volume is given by the formula ...
V = 1/3s²h
where s is the side length of the square base, and h is the height.
V = (1/3)(3 cm²)(8 cm) = 24 cm³
The volume of the pyramid is 24 cm³.

Expanding a garden. The dimensions are 25 feet by 25 feet. I bought 10 cubic yards of soil. How many inches thick will the new dirt cover
Answer:
The thickness of the new dirt cover is 0.144 yards.
Step-by-step explanation:
Dimension of garden = 25 feet by 25 feet.
Volume of soil bought = 10 cubic yards
Volume = length x width x height
But,
1 foot = 0.333333 yard
So that,
25 feet = 25 x 0.333333
= 8.33333 yards
The new dimension of the garden = 8.33333 yards by 8.33333 yards.
Let the thickness of the new dirt cover be represented by h.
Thus,
Volume = 8.33333 x 8.33333 x h
10 = 69.44439 x h
h = [tex]\frac{10}{69.44439}[/tex]
= 0.144
h = 0.144 yards
The thickness of the new dirt cover is 0.144 yards.
Line d has a slope of 3/2. Line e has a slope of -2/3. Are line d and line e parallel or
perpendicular?
Answer:
We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel. Unlike parallel lines, perpendicular lines do intersect
The directions for a food coloring used in frosting say to use 1/8 of coloring for every 2 cups of frosting. If you increase the amount of frosting to 3 cups, which proportion can she use to determine the new amount of coloring needed?

1.Write the equation in point-slope form with the given slope of -2 and passes through the point (4,-5)
2. Write the equation in slope-intercept form of the line parallel to y=4x-2 and passes through (4,6)
3. Write the equation in slope-intercept form with the given slope of 3 and passes through (-1,1)
4. Write the equation in slope-intercept form of the line perpendicular to 2x-7y=1 and passes through (0,-4)
The equation in point-slope form: y - y₁ = m(x - x₁)
slope: m = -2
point: (4, -5) ⇒ x₁ = 4, y₁ = -5
Therefore, the equation of the line in point-slope form:
y + 5 = -2(x - 4)2.The equation in slope-intercept form: y = mx + b
Parallel lines has the same slope, so:
y = 4x + 2 ⇒ a = 4
If a line passes through the point (x₁, y₁) then the equation y₁ = mx₁ + b is true.
(4, 6) ⇒ x₁ = 4, y₁ = 6
So: 6 = 4·4 + b ⇒ b = -10
Therefore the equation:
y = 4x - 103.a = 3
(-1, 1) ⇒ x₁ = -1, y₁ = 1
So: 1 = 3·(-1) + b ⇒ b = 4
The equation:
y = 3x + 44.The product of slopes of perpendicular lines is -1.
2x - 7y = 1 ⇒ 7y = -2x + 1 ⇒ y = -²/₇x + ¹/₇
-²/₇×m = -1 ⇒ m = ⁷/₂
(0, -4) ⇒ x₁ = 0, y₁ = -4
-4 = ⁷/₂·0 + b ⇒ b = -4
The equation:
y = ⁷/₂x - 4find the lenght of gh

Jane's cell phone plan is $58 each month plus $0.20 per minute for each minute over 200 minutes of call time. Jane's cell phone bill last month was $67.00. Write an equation that can be used to determine the number of minutes over 200 that Jane was billed. How many minutes over 200 was Jane billed last month?
Answer: 45 minutes more than 200
Step-by-step explanation:
So for every minute over 200 jane has to pay 0.20 cents per additional minute. The equation we can use is $58+0.20m=$67 where m is the amount of minutes after 200 jane has to pay 20 cents per
58+0.20m=67
0.20m=9
m=45
So Jane was billed for 45 minutes over 200 minutes last month. so in total 245 minutes and she was charged for the extra 45 minutes
A is the point with coordinates (4, 6)
B is the point with coordinates (d, 21)
The gradient of the line AB is three.
Work out the value of d.
The gradient is the slope.
Slope is the change in y over the change in x.
3 = (21-6) / (d-4)
Simplify:
3 = 15/(d-4)
(D-4) = 15/3
D-4 = 5
Add 4 to both sides :
D = 9

Answer:
Step-by-step explanation:
50 elevens-1 elevens = ( 50 -1 ) elevens = 49 elevens
or 49 x eleven = 49 x 11 = _______ (use your calculator here)
Answer:
( 50 -1 ) elevens = 49 elevens = 49 x 11 = 539
or
50 elevens - 1 elevens = (50 x 11) - (1 x 11)
550 - 11 = 539
