Answer:
1.6 hours
Step-by-step explanation:
Given that:
Time spent by Pittsburgh teens, p= 15. 8 hours
Time spent by Miami teens, m = 14.2 hours
The difference in time spent by the teens from these two cities is given by:
Time spent by Pittsburgh teens - Time spent by Miami teens
p - m
15.8 - 14.2 = 1.6 hours
enter the value for x that makes the equation, 4(x - 4) = 12x + 16 true.
Answer:
False your answer will 4x-16
Step-by-step explanation:
you have to distribute 4 to x and 4 to 4. so you will do 4*x=4x and 4*4=16. Now you still have the subtraction sign so your answer will be 4x-16.

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

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.
What is the law of negative exponents in word form.
Answer:
The negative exponent rule tells us that a number with a negative exponent should be put in the denominator, or the numerator, depending on where the number is.

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.

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

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

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
