The basement for a house is being excavated and the rectangular hole measures 11m by 14,5m by 4m. The soil is being hauled away in a dump truck which has an open-box bed of 4m by 3m by 200 cm . The truck Cant be overloaded at any time. How many trips will the dump truck have to make a haul away all of the soil.
Using volume of a rectangular prism, it is found that the dump truck will have to make 266 trips to haul away all of the soil.
What is the volume of a rectangular prism?The volume of a rectangular prism of length l, width w and height h is given by:
[tex]V = lwh[/tex]
In this problem, both the hole and the open-box bed are rectangular, hence the number of trips is the ratio between the volumes of the hole and of the open-box bed.
What is the volume of the volume of the hole?The dimensions in meters are [tex]l = 11, w = 14.5, h = 4[/tex], hence:
[tex]V_h = 11(14.5)(4) = 638[/tex]
What is the volume of the volume of the open-box?The dimensions in meters are [tex]l = 4, w = 3, h = 0.2[/tex], hence:
[tex]V_b = 4(3)(0.2) = 2.4[/tex]
What is the ratio of the volumes?It's their division, hence:
[tex]r = \frac{V_h}{V_b} = \frac{638}{2.4} = 265.8[/tex]
Rounding up, the dump truck will have to make 266 trips to haul away all of the soil.

The mean absolute deviation of a data-set is the sum of the absolute value of the difference between each observation and the mean, divided by the number of observations.
The mean absolute deviation represents the average by which the values differ from the mean.
In this problem, the data-set is: {101, 115, 124, 125, 173, 165, 170}.
Hence, the mean is:
[tex]M = \frac{101 + 115 + 124 + 125 + 173 + 165 + 170}{7} = 139[/tex]

Solve the right triangle. Round to the nearest degree and nearest tenth of a unit. What is the right angleX?
Answer:
m∠X ≈ 29°
Step-by-step explanation:
The hypotenuse and the side adjacent to angle X are given. The relevant trig relation is ...
Cos = Adjacent/Hypotenuse
cos(X) = XW/XV = 7/8
The inverse cosine function is used to find the angle.
X = arccos(7/8) ≈ 29°
WILL IVE BRAINLIEST IF CORRECT AND HURRY A rectangle has an area of 77 square inches and a width of 5.5 inches.
What is the length, l, of this rectangle?
l = 14 in.
l = 22 in.
l = 33 in.
l = 63 in.
Answer:
length = 14 in
Step-by-step explanation:
→ Write the formula for the area of a rectangle
length × width = area
→ Substitute in the numbers
length × 5.5 = 77
→ Divide both sides by 5.5
length = 14

Two grapefruits and three oranges cost $1.95. Three grapefruits and two oranges cost $2.05.
What are the costs of one grapefruit and one orange?
Answer:
one orange costs $0.35 and one grapefruit costs $0.45Step-by-step explanation:
let grapefruits be g , let oranges be o
so first equation:
→2g + 3o = $1.95
→g = ($1.95 - 3o)/2
so second equation:
→ 3g + 2o = $2.05
→ g = ($2.05 - 2o)/3
Solving simultaneously:
→ ($2.05 - 2o)/3 = ($1.95 - 3o)/2
→ 2($2.05 - 2o) = 3($1.95 - 3o)
→ 4.1 - 4o = 5.85 - 9o
→ - 4o + 9o = 5.85 - 4.1
→ 5o = 1.75
→ o = $0.35
Therefore one orange costs $0.35
Then one grapefruit costs g → ($1.95 - 3o)/2
→ g = ($1.95 - 3(0.35))/2
→ g = 0.45
Therefore one grapefruit costs $0.45
Carly’s bake shop requires 3.5 hours of labor to produce one cake and 2 hours of labor to produce one pie, and the shop has a maximum of 70 total labor hours available. If X1 represents number of cakes and X2 represents number of pies, how would this constraint be written?
Step-by-step explanation:
3.5 hours for 1 cake means 3.5 hours per cake.
similar : 2 hours for 1 pie means 2 hours per pie.
so, if there are e.g. 3 pies, they take 3×2 = 6 hours.
therefore the general constraint is
3.5x1 + 2x2 <= 70
I think the names "x1" and "x2" are confusing when writing this inequality.
I prefer to use x and y.
and then it would look like
3.5x + 2y <= 70
