Shawn's family car holds 16 gallons of fuel. Each day the car uses 0.8 gallons to get to school and back. A warning light comes on when there is less than 1.5 gallons left in the fuel tank. How many days can Shawn drive the car before the warning lights come on?
Given :
Shawn's family car holds 16 gallons of fuel.
Each day the car uses 0.8 gallons to get to school and back.
A warning light comes on when there is less than 1.5 gallons left in the fuel tank.
To Find :
How many days can Shawn drive the car before the warning lights come on.
Solution :
Let, after x days warning come.
So,
[tex]16 - 0.8x < 1.5\\\\16-1.5<0.8x\\\\0.8x > 14.5\\\\x > \dfrac{14.5}{0.8}\\\\x > 18.125[/tex]
Therefore, at 19th day the warning light will start glowing.
Hence, this is the required solution.

A scale drawing of a lake has a scale of 1 cm to 80 m. If the actual width of the lake is 1,000 m, what is the width of the lake on the scale drawing? Answers with fractions must be entered at a decimal. For example 1 1/2 would be 1.5 and 1 1/4 would be 1.25.
Answer: 12.5cm
Step-by-step explanation:
From the question, we are informed that a scale drawing of a lake has a scale of 1 cm to 80 m. This can be represented as a fraction of 1/80.
Since the actual width of the lake is 1,000 m, the width of the lake on the scale drawing will be:
= 1/80 × 1000
= 12.5cm
The width of the lake on the scale drawing is 12.5cm.

) Which of these shows a repeating decimal? A 2.222 C 3 6 10B 4.0014(With line ontop the LAST 4)
Answer:
B. 4.0014 repeated
Step-by-step explanation:
because the line above the four means that it's repeated.
Imaginary number test
i ⁴³⁵ = i ⁴³²⁺³ = i ⁴³² • i ³
i ⁴³⁵ = i ⁴³² • i ³
i ⁴³⁵ = (i ⁴)¹⁰⁸ • i ³
i ⁴³⁵ = 1¹⁰⁸ • (-i)
i ⁴³⁵ = -i
The value of the imaginary number i⁴³⁵ is : i ⁴³⁵ = -i.
Here, we have,
To evaluate the expression i⁴³⁵, we need to understand the properties of the imaginary unit, denoted by i.
The imaginary unit i is defined as the square root of -1, meaning i² = -1.
When raising i to an exponent, we can use the pattern of powers of i to simplify the expression.
The pattern of powers of i repeats every four exponents:
i¹ = i
i² = -1
i³ = -i
i⁴ = 1
Since i⁴ = 1, we can divide the exponent 435 by 4 to find the remainder:
435 divided by 4 gives a remainder of 3.
Therefore, i⁴³⁵ is equivalent to i³.
Using the pattern of powers of i, we know that i³= -i.
So, i⁴³⁵ = -i.
i.e. we get,
i ⁴³⁵ = i ⁴³²⁺³ = i ⁴³² • i ³
i ⁴³⁵ = i ⁴³² • i ³
i ⁴³⁵ = (i ⁴)¹⁰⁸ • i ³
i ⁴³⁵ = 1¹⁰⁸ • (-i)
i ⁴³⁵ = -i

Car Bs unit rate is______
Which car goes faster? _____
Answer:
Car As unit rate is --- ***57km/h***
Car Bs unit rate is --- ***70km/h***
Which car goes faster? --- ***Car B*
I hope this helps. u said 45 minutes, so i tried to some up with an answer. best of luck on ur work
Step-by-step explanation:
car a is 57 km in an hour, as 57t is equal to d. This, when d is 57 km will be 1 hr. So we are assuming that "t" is 1. Then d is 57. NOw lets check out car b. 140/2 is for 2 hrs, 210/3 for 3 hrs, and 280/4 for 4 hrs. This gives rate of 70 km in 1 hr.

Caleb was building a birdhouse. He needed 2 boards that were each 6 inches long and one board that was 18 inches long. He was then able to cut the boards into pieces to use.
Answer: 30 inches
Step-by-step explanation:
Here is the complete question:
Caleb was building a birdhouse. He needed 2 boards that were each 6 inches long and one board that was 18 inches long. He was then able to cut the boards into pieces to use. What was the total length of the boards that he needed?
From the question, we are informed that Caleb needed 2 boards that were each 6 inches long and one board that was 18 inches long.
The total length of the boards that he needed goes thus:
For the first part, we are told that Caleb needed 2 boards that were each 6 inches long. This means that he needs a total of (2 × 6 inches) = 12 inches.
We are also told that he needed one board that was 18 inches long. This mean the total length of the birds needed will be the addition of the length of all the three boards. This will be:
= 12 inches + 18 inches
= 30 inches

The formula for the area of a trapezoid is A=\frac{1}{2}h(b_1+b_2),A= 2 1 h(b 1 +b 2 ), where hh is the height and b_1b 1 and b_2b 2 are the two bases. Rewrite the formula to solve for hh in terms of A,A, b_1b 1 and b_2.B 2 .
Question
The formula for the area of a trapezoid is A= 1/2h(b1 + b2),
where h is the height and b1 and b2 are the two bases. Rewrite the formula to solve for h in terms of A, b1 and b2
Answer:
h = 2A/b1 + b2
Step-by-step explanation:
Area of a Trapezoid
= 1/2h(b1 + b2)
Rewriting the formula to solve for h, this means making h the subject of the formula
A = 1/2h(b1 + b2)
Cross Multiply
2A = h(b1 + b2)
Divide both sides by b1 + b2
h(b1 + b2)/b1 + b2 = 2A/b1 + b2
Therefore,
h = 2A/b1 + b2

Yes, Converse of Corresponding Angles Postulate
Yes, Converse of Alternate Interior Angles Postulate
Yes, Converse of Alternate Exterior Angles Postulate
Yes, Converse of Consecutive Interior Angles Postulate
Answer:
Option (1)
Step-by-step explanation:
From the picture attached,
Lines 'm' and 'n' are the parallel lines and 'r' is a transversal line intersecting these lines at two distinct points.
Therefore, both the angles will be congruent by the property of corresponding angles postulate.
By the converse of corresponding angles postulate,
If these angles are congruent then both the lines (m║n) will be parallel.
Option (1) will be the answer.

A ball is rolled down the hill at 3 m/s. The hill is 36 meters long. How
many seconds does it take the ball to reach the bottom of the hill? *
Answer:
12 seconds
Step-by-step explanation:
To do this you would take the rate of the ball, (the 3 m/s) and divide it from how big the hill is, (36 m)
36/3=12 seconds
So the ball would reach the bottom of the hill in 12 seconds

Answer:
5 1/4 inches
Step-by-step explanation:
In 1 week, 1 1/6 inches decreases
In 1/2 week, 7/6 /2 =7/12 inches decreases
In 4 weeks, 4* 1 1/6 = 4* 7/6 = 14/3 inches decreased
In 4 1/2 weeks, 7/12 + 14/3 = 7/12 + 56/12 = 63/12 = 5 3/12 = 5 1/4 inches decreased

4d + 5 - 9d + 2 = 13
Answer: d = -1.2
Step-by-step explanation: First you combine like terms. You add 5 +2 which gives you 7, and then you subtract 9 from 5 which gives you -5d. Then you subtract 7 from 13 which gives you 6. Divide both sides by -5 and you get -1.2. Always make sure to check your answer by plugging your answer into the place of the d variable
