Answer:
The angle between the ramp and the horizontal is 11.54 degrees
Step-by-step explanation:
Here, we want to get the angle between the ramp and the horizontal
What we have to do here is to bring the measure of 2 m near to the edge leftwards, so we can have a right triangle
Now, the angle we want to calculate is the angle that faces the measure 2 m
The given measure of 10 m will represent the hypotenuse of the right triangle
The trigonometric ratio that links the hypotenuse and the opposite is the sine
The sine is the ratio of the opposite to the hypotenuse
Thus, we have it that;
sin theta = opp/hyp
sin theta = 2/10
sin theta = 0.2
theta = sin^-1 0.2
theta = 11.54

Jim rented a truck for one day. There was
base fee of $17.95, and there was an additional charge of 87 cents for each mile driven, Jim had to pay $153.67
when he returned the truck. For how many miles did he drive the truck?
Answers
Y = 17.95 + 0.87x
Y = total cost, x = miles
153.67 = 17.95 + 0.87x
135.72 = 0.87x
x = 156 miles
Answer:
Jim drove the truck 156 miles
Step-by-step explanation:
Represent the number of miles driven with x.
Then the formula for the total rental cost is C(x) = $17.95 + ($0.87/mile)x, and this comes to $153.67. Solve for x:
$153.67 - $17.95 = ($0.87/mile)x, or
$135.72 = ($0.87/mile)x
Dividing both sides by ($0.87/mile), we get:
x = 156
Jim drove the truck 156 miles

A new car is purchased for $26,000 and over time its value depreciates by one half every 5 years. What is the value of the car years after it was purchased to the nearest hundred dollars?
Answers
Answer: $6,500
Step-by-step explanation:
Question says after 10 years.
The value of the car depreciates by 1/2 every year which is 50%, every 5 years.
In 10 years therefore, the car would have depreciated by half of its value, twice.
Use the future value formula:
= Amount * (1 + rate) ^ no. of periods
= 26,000 * ( 1 - 50%)²
= $6,500
Note: There are two periods because the depreciation is every 5 years and 10 years have gone by so the number of periods is: 10 / 5 = 2 periods

Answers
Answer:
Subtract 8 from both sides of the inequality. Divide both sides of the inequality by 3.
Step-by-step explain
The given inequality is 3b + 8 ≥ 14
We need to solve the given inequality
Step 1.
Subtract 8 to the both sides of the inequality
3b + 8 - 8 ≥ 14 -8
3b ≥ 6
Dividing both sides by 3
b ≥ 2
The value of b is greater than and equal to 2.

Jackie bought a 3-pack of tubes of glue. She used 0.27 ounce of the glue from the 3-pack
and had 1.35 ounces left in total. Which describes a way to determine the number of ounces
sold in each tube of glue?
Divide 1.35 by 3 and then subtract 0.27 from the quotient.
Solve for in the equation 3 (x - 0.27) = 1.35.
Solve for x in the equation 3x - 0.27 = 1.35.
Subtract 0.27 from 1.35 and the divide the difference by 3.

Answers
Answer:
4
Step-by-step explanation:
9+3=12
12x1/2=24
24/6=4
h=4
Height of trapezoid is,
⇒ h = 4 km
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
The area of the trapezoid is 24 Square km.
We know that;
Area of Trapezoid = (a + b) h / 2
Here, A = 24 km² , a = 3 km , b = 9 km
Hence, We get;
24 = (3 + 9) h / 2
48 = 12h
h = 48 / 12
h = 4 km
Thus, Height of trapezoid is,
⇒ h = 4 km

80 g butter
4 eggs
180 ml milk
Jill makes a fish pie for 3 people. Work out how much flour she needs.
Answers
Step-by-step explanation:
Given
6 people = 180g flour
1 person = 180/6 = 30g flour
3 people = 3 x 30 = 90g flour
Step 1 = 180g for 6 people
Step 2 = first u need to find how much for one person u do that by dividing 180 by 6 which is 30
step 3 = now that u know 30 is for one person u times 30 by 3 = 90
Step 4 = so the answer is 90g

P is the incenter of △JKL. Find m∠JKP.
& can you please explain
Answers
Answer:
∠JKP = 35°
Step-by-step explanation:
since P is the incenter, then lines to incenter bisect the corner angles:
7x - 6 = 5x + 4
subtract 5 x from both sides of the equation:
2x - 6 = 4
add 6 to each side:
2x = 10
divide both sides by 2:
x = 5
∠KJP = 7(5) - 6 = 29°
∠LJP = 5(5) + 4 = 29°
then ∠KJL = 29° + 29° = 58°
∠KLJ = 26° + 26° = 52°
∠JKL = 180° - 58° - 52° = 70°
∠JKP = 1/2 ∠JKL = 1/2(70°) = 35°

Since triangle 2 is a right triangle, write an equation applying the Pythagorean Theorem to the triangle.
Answers
Answer: a^+b^2=n^2
Step-by-step explanation:
The equation for triangle 2 will be: a² + b² = n².
What is Pythagorean theorem?
Pythagorean theorem states that for a right-angle triangle, the sum of the squares of the base and the height is equal to the square of the hypotenuse of that triangle.
Here, the angle between side: a and side: b is a right-angle.
Therefore, we can consider side: a as the height and side: b as the base of the triangle.
Therefore we can write as per the Pythagorean theorem:
(Base)² + (Height)² = (Hypotenuse)²
Hence, a² + b² = n²
