Gas is priced at $2.70 per gallon. My gas tank has 2 gallons currently in the tank. Write an equation to show much
money I will spend to fill up my tank.
Answer:
The equation is
2.7x - 5.4
Step-by-step explanation:
Gas is priced at $2.70 per gallon. My gas tank has 2 gallons currently in the tank. Write an equation to how much
the money I will spend to fill up my tank.
Let the total gallons that would fill your tank = x
The tank currently has 2 gallons
A gallon =>$2.70
Therefore, our equation is
=(x - 2) × 2.70
= 2.7x - 5.4

A tire on Tom's car weighs 21 2/3 pounds. All 4 tires have the same weight. Which is the total weight of the 4 tires on Tom's car?
Answer:
86.6666666667
Step-by-step explanation:
Because one of Tom's car wheel weighs 21 2/3 pounds, you would have to multiply 21 2/3 pounds by 4 to get the amount of pounds that all the tires weigh; which makes the answer:86.6666666667
Answer:
86 2/3
Step-by-step explanation:
you multiply 21 × 4 and get 84
multiply 2 × 4 and get 8
Divide 8/3 and get 2 2/3
add 2 to 84
and leave the 2/3

Please help! Having trouble.
Answer:
B. 13
Step-by-step explanation:
Let's solve your equation step-by-step.
7√x−4−6=15
Step 1: Add 6 to both sides.
7√x−4−6+6=15+6
7√x−4=21
Step 2: Divide both sides by 7.
7√x−4
7
=
21
7
√x−4=3
Step 3: Solve Square Root.
√x−4=3
x−4=32(Square both sides)
x−4=9
x−4+4=9+4(Add 4 to both sides)
x=13
Answer:
x = 13
Step-by-step explanation:
[tex]7 \sqrt{x - 4} = 15 + 6 \\ 7 \sqrt{x - 4} = 21 \\ \sqrt{x - 4 =} = 3 \\ x - 4 = 9 \\ x = 13[/tex]
(6.8 X10)–(7.2 X 10)
1.1 X 104
X 10
Go to two decimal places
Answer:
5.53 * 10^-1
Step-by-step explanation:
[(6.8 * 10^3) - (7.2 * 10^2)] ÷ 1.1 * 10^4
(6800 - 720) ÷ 11000
6080 ÷ 11000
6.08 * 10^3 ÷ 1.1 * 10^4
(6.08 ÷ 1.1) * 10^3-4
5.527 * 10^-1
= 5.53 * 10^-1

Moe painted the lid of the barrel. The circumference of the barrel is 32*3.14 inches. What is the area of the lid in square inches?
Answer: 803.84 inch²
Step-by-step explanation:
The lid will take the appearance of a circle so the area of the lid is the same as the area of a circle:
Area of a circle = π * radius²
The circumference of a circle is:
= π * diameter
Looking at the above, the diameter is 32inches because this is the figure to be multiplied with π = 3.14 to find the circumference.
Since diameter is 32, radius will be:
= 32 / 2
= 16 inches
Area = 3.14 * 16 * 16
= 803.84 inch²
Solve the right triangle. Find ST, m
Round your answers to the nearest whole number.
Answer:
st=22
m<r=68
m<t=22
Step-by-step explanation:
Side rt = 24
Side sr = 9
Side st = 22.2486
Angle ∠s = 90° = 1.5708 rad = π/2
Angle ∠t = 22.024° = 22°1'28" = 0.3844 rad
Angle ∠r = 67.976° = 67°58'32" = 1.1864 rad

16% of students scored higher than 80 on a recent normally distributed exam the standard deviation is 10 what is the mean
Answer:
70.06
Mean score = 70
Step-by-step explanation:
16% of students scored higher than 80 on a recent normally distributed exam the standard deviation is 10 what is the mean
For a normal distribution :
Zscore = (x - mean) / standard deviation
x = score
P(Z > 80) = 16% = 0.16 ; corresponding Zscore = 0.994 (Z probability calculator)
Therefore ;
0.994 = (80 - mean) / 10
0.994 * 10 = 80 - mean
9.94 = 80 - mean
Mean = 80 - 9.94
Mean = 70.06
Hence, the mean score = 70.06 = 70
You have three sticks. Each stick has one red side and one blue side. You throw the sticks 10 times and record the results. Use the table to find the experimental probability of the event.
Answer:
4 + 4 + 2 = 10
3) 3/10 or 0.3
4) 2/10 = 1/5 or 0.2
5) 4/10 = 2/5 or 0.4
6) 2 + 4 + 0 = 6 so 6/10 = 3/5 or 0.6

Substitution
1.y=-5x-19
y=-6x-24
2.y=-6x-22
y=-3x-10
Answer:
1. y=5 and x=-5
2. y=2 and x=-4
Step-by-step explanation:
1.y=-5x-19
y=-6x-24
since both equations are equal to y, they are also equal to eachother
-5x-19=-6x-24
addition P.O.E.
x-19=-24
addition P.O.E.
x=-5
substitute x into one equation
y=-5*-5-19
y=6
2. y=-6x-22
y=-3x-10
since both equations are equal to y, they are also equal to eachother
-6x-22=-3x-10
addition P.O.E.
-22=3x-10
addition P.O.E.
-12=3x
division P.O.E.
-4=x
substitute x into one equation
y=-3*-4-10
y=2

What is 11/12 + 2 1/6 ?
Either decimal or fraction.
Answer:
3.0833
Step-by-step explanation:
i dont know how many 3's
Answer: 37/12
Step-by-step explanation: First you must turn 2 1/6 into a improper fraction, so 2x6 + 1 will get you 13 as the numerator and the denominator will be 6 so now we have 13/6 + 11/12. Now we must turn the denominator for 13/6 into 12 so, 13x2/6x2 so it is 26/12 so now the equation is 26/12 + 11/12 is 37/12.
