Step-by-step explanation:
Simplify the equation to find the value of a.
Subtract 4a from both sides:
[tex] - 3a - 15 = - 3[/tex]
Add 15 to both sides:
[tex] - 3a = 12[/tex]
Divide each side by -3:
[tex]a = - 4[/tex]

Step-by-step explanation:
An engineer is designing a large steel pad to be installed on the deck of an aircraft carrier. Its total volume will be 18 yd^3. A scale model made of the same material measuring 6 feet by 4.5 feet and 4 inches thick weighs 75 lbs. If the steel costs $55/lb, how much will the material for the full-sized steel pad cost?
a) 12,375.00
b) 55,687.50
c) 82,500.00
d) 222,750.00
Answer:
The cost of the material for the full-sized pad is;
d) 222,750.00
Step-by-step explanation:
The parameters of the steel pad and the scale model are;
The volume of the deck = 18 yd³
The dimensions of the model of the same material = 6 feet by 4.5 feet and 4.5 inches thick
The weight of the sample, m₂ = 75 lbs
The cost of the steel, P = $55/lb
The dimensions of the sample in yards are;
6 feet = 2 yards, 4.5 feet = 1.5 yards, and 4 inches = 0.[tex]\overline 1[/tex] yards
The volume of the sample, V₂ = 2 yd. × 1.5 yd. × 0.[tex]\overline 1[/tex] yd. = (1/3) yd.³
The density of the sample material, ρ = m₂/V₂
∴ The density of the sample material, ρ = 75 lbs/((1/3)yd.³) = 225 lbs/yd³
Therefore, the density of the material of the pad, ρ = 225 lbs/yd³
The mass of the steel pad, m₁ = ρ × V₁
∴ The mass of the steel pad, m₁ = 225 lbs/yd³ × 18 yd³ = 4,050 lbs
The cost of the material for the full-sized steel pad, C = m₁ × P
∴ C = 4,050 lbs × $55/lb = $222,750

Answer:
Area = 52√3
A
Step-by-step explanation:
Remark
This is a trapezoid. The formula for a trapezoid is Area = 1/2 (b1 + b2)* h/2
Givens
b1 = 11
b2 = 15
h = 4*√3
Solution
Area = 1/2 (15 + 11 )*4*√3
Area = 1/2(26)*4√4
Area = 13 * 4√3
Area = 52√3

Scale on map is Lin 86 mi if actual distance is 35 mi . Between two cities how far apart on the map are they
Answer:
0.41 cm
Step-by-step explanation:
The scale on the map is 1 in 86 mi.
This means that, 1 cm on the map represents 86 miles in real life, or on earth.
Then we're told that in real life, a distance is 35 miles, and how far they are on the map.
If 1 cm equals 86 miles, then we can say that x cm equals 35 miles
1 cm ----> 86
x cm ----> 35
x * 86 = 35 * 1
x = 35 / 86
x = 0.41 cm
Therefore, they must be 0.41 cm farther or closer apart on the map scale.

C. 24.6 / 0.006
D. 2.46 / 0.006
Answer:
Step-by-step explanation:
Remark
The larger the numerator and the smaller the denominator, the bigger the quotient. Try and get the answer using that rule.
C
24.6 / 0.006 = 4100 Nothing is bigger than that.

divide through by 7
x= 8
(b) 4n = 48
divide through by 4
n = 12
(b) 5c = 80
divide through by 5
n = 16
Answer:
a. 8
b. 12
c. 16
Step-by-step explanation:
7x= 56
You have to get x alone so divide
Divide by 7 to get answer (whatever you do to one side, do to the other)
x= 8
EDIT:
4a. 7x=56
7x/7 = 56/7
x= 8
4b. 4x=48
4x/4=48/4
x= 12
4c. 5c= 80
5c/5=80/5
c=16
the same goes for the rest

One of the legs of a right triangle measures 5 cm and its hypotenuse measures 10 cm.
Find the measure of the other leg. If necessary, round to the nearest tenth.
Answer: 12 cm
Step-by-step explanation:
If one of the legs of a right triangle measures 5 cm and its hypotenuse measures 10 cm. Then the measure of the other leg will be 8.66 cm.
What is a Pythagoras theorem?The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
One of the legs of a right triangle measures 5 cm and its hypotenuse measures 10 cm.
Then the measure of the other leg will be
10² = 5² + B²
100 = 25 + B²
B² = 75
B = 8.66 cm

what polygon is formed?
Answer:
Polygons are figures that are formed by three or more line segments. These line segments, even called sides, meet at their endpoints to form vertices. If we compare the number of sides, diagonals and triangles of a quadrilateral a pentagon and a hexagon we can find a system between the different polygons.

Answer:
I got you bro so the sales tax is $0.80 and the total cost is $10.80
Answer:
Sales tax = $0.8Total cost = $10.8Step-by-step explanation:
Now we have to,
→ find sales tax and total cost.
The sales tax will be,
→ 8% of $10.00
→ (10/100) × 8
→ 80/100
→ $0.8
Now the total cost will be,
→ $10 + sales tax
→ 10 + 0.8
→ $10.8
Hence, total cost is $10.8.
