1,800 kilometers in 75 hours = ______ kilometers per hour
Answer:
24 kilometers per hour
Step-by-step explanation:
Distance = Rate x time
You need to divide the number of kilometers by the number of hours it took.
1800 kilometers = 75 hours1800 kilometers ÷ 75 = 1 hour24 kilometers per hour-Chetan K
A large cheese pizza cost $7.40. Diego has $40 to spend on pizzas. How many large cheese pizzas can he affors?
Answer:

What is the length of the hypotenuse, c? Round your answer to the nearest hundredth.
Answer:
Step-by-step explanation:
By using the Pythagorean theorem:
b^2+3^2=5^2
b^2+9=25
b=sqrt (25-9)
b=sqrt(16)
b=4
=> 4^2+7^2=c^2
16+49=c^2
65=c^2
=>c=sqrt(65)
c = (approximately) 8
-1 < x < 4
x is an integer.
Write down the possible values of x.
Answer:
0, 1, 2, 3
Step-by-step explanation:
-1 < x < 4 means that x has to be an integer (whole number aka no fractions) between -1 and 4. Note that the < and > means that x cannot be -1 or 4 since it has to be greater than -1, or smaller than 4.
What is the volume of a right circular cylinder with a base diameter of 6 m and a height of 5 m? Enter your answer in the box. Express your answer using π. M³ $\text{Basic}$.
The volume of the cylinder depends on its radius and height. The volume of the cylinder is 141.3 m3.
What is the volume of the cylinder?The volume of the cylinder is defined as the density of the cylinder which measures the amount of material contained by the cylinder.
Given that the height h of the cylinder is 5m and the diameter d of the base of the cylinder is 6m.
The radius of the cylinder is given below.
[tex]r = \dfrac {d}{2}[/tex]
[tex]r= \dfrac {6}{2}[/tex]
[tex]r = 3\;\rm m[/tex]
The volume of the cylinder is calculated as given below.
[tex]V = \pi r^2 h[/tex]
[tex]V = 3.14 \times 3^2 \times 5[/tex]
[tex]V = 141.3 \;\rm m^3[/tex]
Hence we can conclude that the volume of the cylinder is 141.3 m3.

Answer:
The answer is B.
3x + 5y = 24
4x + 3y = 21
Step-by-step explanation:
x = cost of a chocolate chip cookie
y = cost of an oatmeal cookie
3x + 5y = 24
4x + 3y = 21
Lets solve:
-3(3x + 5y = 24) ==> -9x - 15y = -72
5(4x + 3y = 21) ==> 20x + 15y = 105
Let's add our new equations:
-9x - 15y = -72
20x + 15y = 105
11x = 33
/11 /11
x = $3.00 (the cost of each chocolate chip cookie)
Now lets find the cost of each oatmeal cookie using one of our original equations: 3x + 5y = 24
3(3) + 5y = 24
9 + 5y = 24
-9 -9
5y = 15
/5 /5
y = $3 (the cost of each oatmeal cookie)
Each type of cookie (chocolate chip and oatmeal), costs $3.00

A tree is 4 ft 2 in. Tall. To find the height of a tower, the shadow of the tree and the shadow of the tower were measured. What is the height h of the tower?.
Answer:
20 ft
Step-by-step explanation:
Convert all measurements to a single unit, inches, using the fact that 1 foot is equal to 12 inches.
ZY=(24⋅12) in.

RQ=60 in.
ZX¯¯¯¯¯ and QH¯¯¯¯¯¯ are parallel because the rays of the Sun that form them are parallel. Therefore, the angles they form with the ground
are congruent: ∠Z≅∠Q.
∠Y≅∠R by the Right Angle Congruence Theorem.
Therefore, by the Angle-Angle Similarity △ZXY~△QHR.
Find XY. Set up a proportion with the lengths of the known sides and the unknown length (height of the tower).
ZYQR=XYHR
Substitute the values.
28860=h50
Cross multiply.
60h=50(288)
Simplify.
60h=14400
Divide both sides by 60.
h=240
The height of the tower is 240 in., or 20 ft.
I'm very confused, can someone explain this to me?
Answer: 118 degrees
Step-by-step explanation:
By the exterior angle theorem.
3x + 12 + 2x + 16 = 6x + 10
5x + 28 = 6x + 10
x = 18
So measure of angle 3 = 6(18) + 10 = 118 degrees

if you are diving from a diving board that is 20 feet in the air, into a pool. When jumping into the pool, you touch the bottom in the 10-foot section of the pool. How far did you fall from the diving board to the bottom of the pool? (sentence required)
Answer: 30 feet
Explanation:
Draw a vertical number line.
Mark +20 or simply 20 which is the starting position at the diving board. The value 0 on the number line is the water's surface. The position -10 is the portion 10 feet at the bottom of the pool.
Going from 20 to 0 is 20 feet. Then going from 0 to -10 is another 10 feet.
Overall, you travel 20+10 = 30 feet.
The following table shows the working populations, average salaries, and income tax rates of France and Germany. Country Workforce Average Salary (€) Income Tax Rate France 31,491,232 29,766 69. 3% Germany 38,844,017 32,104 45. 2% Based on the information in the table, how do the annual tax revenues of Germany and France compare to one another? a. The French government gathers €85,930,190,677 more than the German government. B. The French government gathers €543,141,128,984 more than the German government. C. The German government gathers €309,680,310,056 more than the French government. D. The German government gathers €223,750,119,378 more than the French government.
Percentage is a way to describe a part of a whole. French government gathers €85,930,190,677 more than the German government.
What is Percentage?A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
We know that the number of people who are working in France is 31,491,232 and their average salary is €29,766 while the amount of tax they pay from their salary is 69.3%. therefore, the total amount of tax that France will gather,
[tex]Tax_{France} = 31,491,232 \times 29,766 \times 69. 3\%[/tex]
[tex]= 31,491,232 \times 29,766 \times \dfrac{69. 3}{100}\\\\= 31,491,232 \times 29,766 \times 0.693\\\\=6.49596\times 10^{11}[/tex]
Now, the population that is working in Germany is 38,844,017 while the average earning of the population is €32,104 and they pay 45.2% of their salary as tax. therefore,
[tex]Tax_{Germany} = 38,844,017 \times 32,104 \times 45.2\%[/tex]
[tex]= 38,844,017 \times 32,104 \times 45.2\%\\\\= 38,844,017 \times 32,104 \times \dfrac{45.2}{100}\\\\= 38,844,017 \times 32,104 \times 0.452\\\\=5.63666 \times 10^{11}[/tex]
Further, the difference between the tax of the two countries can be written as,
[tex]\text{Differene in the tax}= Tax_{France} - Tax_{Germany} = 85,930,190,677[/tex]
hence, the French government gathers €85,930,190,677 more than the German government.

James is riding in a 102-mile bike race.
When he stops for his first water break,
he is told that the second part of the
course is twice as long as the first part.
How long is the first part of the course?
Answer:
The first part of the course is 34 miles
Step-by-step explanation:
If you get 34 miles into a 102 miles bike race, you still have 68 miles left, which is double 34
Answer:
34
Step-by-step explanation:
34 + 68 =102
34×2 =102 so 34 is the answer.
Write the equation in standard form. 4y−5x=3(4x−2y+1)
Answer:
-17x+10y=3
Step-by-step explanation:
Standard form is:
Ax+By=C
Let's start by simplifying the equation:
4y-5x=3(4x-2y+1)
Distribute the 3:
4y-5x=3(4x)+3(-2y)+3(1)
4y-5x=12x-6y+3
Subtract 12x from both sides
4y-17x=-6y+3
Add 6y to both sides
10y-17x=3
-17x+10y=3
