A right triangle with the side AB as a length of 35 cm and another side length BC with 12 cm. What is the hypotenuse length of the right triangle?

Answers

The formula to find the hypotenuse is a^2 + b^2 = c^2. Let’s call side AB, “a” and call side BC, “b”. Now “a” = 35 cm and “b” = 12 cm. Using the formula, you square (multiply the number by itself) “a” and “b” then add them together. This would look like 35^2 + 12^2 =c^2. When you do the multiplication it ends up as 1,225 + 144 = c^2. Add 1,225 and 144 together to get 1,369 = c^2. Last step is to square root both sides to get 37 = c. So the hypotenuse of this triangle would be 37.

A number is 12 more than the other. Find the numbers if their sum is 48​

Answers

Answer:

let one number be x and the other be x + 12

sum = 48

x + x + 12 = 48

2x + 12 = 48

2x = 48 - 12

2x = 36

x = 36 by 2

x = 18

therefore x = 18 and x+12= 18+12=30

so the answer is 18 and 30

in triangle ABC with vertices A(4,5),B(-2,1) and C(0,3),E and F are midpoints of sides AB and AC resp . then, find coordinates of E and F​

Answers

Answer:

The answer is

E=(1, 3)

F=(2,4)

Step-by-step explanation:

When E is midpoint of AB

Then

[tex]e = ( \frac{4 + ( - 2)}{2} . \frac{5 + 1}{2} ) \\ = (1.3)[/tex]

By this way we can find F

[tex]f = ( \frac{4 + 0}{2} . \frac{5 + 3}{2} ) \\ = (2.4)[/tex]

Noah and Lin are marketing paper cones to hold popcorn to hand out at parent math night. They want the cones to hold 9 cubic inches of popcorn. What are two different possible values for height h and radius r for the cones?


if h=3, then r=


if r=2, then h=

Answers

Answer: r = 1.69 inches

              h = 2.15 inches

Step-by-step explanation: Volume of a solid is the amount of space contained within a solid.

Volume of a cone is directly proportional to radius and height:

[tex]V=\frac{1}{3}\pi r^{2}h[/tex]

They want the cones to hold the same volume of 9 cubic inches.

If height is 3:

[tex]9=\frac{1}{3}\pi r^{2}3[/tex]

[tex]\pi r^{2}=9[/tex]

[tex]r^{2}=2.864[/tex]

r = 1.69 inches

When height is 3, radius is 1.69 inches for a cone to have 9 cubic inches of volume.

If radius is 2:

[tex]9=\frac{1}{3}\pi (2)^{2}h[/tex]

[tex]h=\frac{9(3)}{4 \pi}[/tex]

h = 2.15 inches

If radius is 2 inches, height of the cone is 2.15 inches.

y= -3x + 1 and y= x - 3

Answers

Answer:

x= 1

y= -2

Step-by-step explanation:

equation (1): y= -3x+1

equation (2): y=x-3

solve the system of equations by substitution:

step1: sub ( x-3 ) for y in equation 1:

y = -3x+1

x-3 = -3x+1

step2: simplify the equation to get x:

(add 3 for both sides)

x = -3x+4

(add 3x for both sides)

4x = 4

(divide 4 from both sides)

x = 1

step3: sub the value of x (x=1) in equation 2:

y = x-3

y = 1-3

step4: solve the equation to get y:

y = -2

A truck that is 10 ft. by 12 ft. by 8 ft. carries cube shaped boxes that have a
length of 1.5 ft. How many of these boxes can this truck hold?

Answers

Answer:

284.4

Step-by-step explanation:

Divide all numbers by 1.5. example: (10)1.5(12)1.5(81.5= 284.444444 but I rounded it to 284. You're welcome

284 boxes in the shape of the cubes can be fitted in the truck.

If a truck is fitted fully with the cubes, volume of the truck will be equal to the volume of cubes to be fitted.

Dimensions of the truck given in the question,

Length = 10 feet, width = 12 feet and height = 8 feet

Since, volume of a cuboid (shape of a truck) is given by the expression,

Volume = Length × Width × Height

Therefore, volume of the truck = 10 × 12 × 8

                                                   = 960 feet³

Volume of a cube is given by the expression,

Volume = (side)³

Therefore, volume of the cube with side length 1.5 feet will be,

Volume of a cube = (1.5)³

                              = 3.375 cubic feet

Let the number of cubes fitted in the truck = x

Therefore, volume of 'x' cubes = (3.375x) feet³

Since, volume of the truck = Volume of the cubes fitted

3.375x = 960

x = [tex]\frac{960}{3.375}[/tex]

x = 284.44

x ≈ 284

     Therefore, 284 boxes in the shape of the cubes can be fitted in the truck.

Solve the simultaneous equations
5x + 3y = 41
2x + 3y = 20
Do not use trial and improvement

Answers

5x + 3y = 41
2x + 3y = 20
Solve 3y
-> 3y = 41 - 5x
Substitute
2x + 41 - 5x = 20
-3x = 20 - 41
= -21
x= 7
Substitute
2x + 3y = 14 + 3y = 20
3y = 6
y = 2
=> x=7, y=2

The solution to the system of equation is (7, 2)

Using the simultaneous equation:

5x + 3y = 41

2x + 3y = 20

using elimination method

Subtract equation 1 from 2 to have:

5x - 2x = 41 - 20

3x = 21

x = 21/3

x = 7

Substitute x = 7 into equation 1 to get y

5x + 3y = 41

5(7) + 3y = 41

35 + 3y = 41

5y = 41 - 35

3y = 6

y = 6/3

y = 2

Hence the solution to the system of equation is (7, 2)

Four major candidates ran in the 1824 election, all under the "Democratic-Republican" name. One of the candidates, Andrew Jackson, was already famous. In the 1780s, he earned the right to practice law and served in various offices of the state government, including senator. He earned the nickname "Old Hickory" for his toughness as a general during the War of 1812 and First Seminole War. Jackson supported slavery and "Indian removal." This earned him support from voters in southern and frontier states. The other three candidates were John Quincy Adams of Massachusetts, Henry Clay of Kentucky, and William Crawford of Georgia. U.S. presidents are elected through the Electoral College. The Founding Fathers worried that Americans were to spread out to learn enough about the candidates. Under the Electoral College, Americans cast their ballot for the popular vote, which chooses the electors for each state. The number of electoral votes each state equals the number of representatives and senators combined. The candidates must win an absolute majority of electoral votes to win the election. In 1824, Andrew Jackson won the popular vote, but he did not win it in each state. Jackson and Adams both won many electoral votes. Jackson won the most with 99. However, a candidate needs an absolute majority of electoral votes to win. In 1824, Jackson needed 131 to win. When there is not majority winner, the election goes to the House of Representatives. This has only happened twice in U.S. history. Even though he won the popular vote and many electoral votes, Andrew Jackson lost the presidency in 1824. John Quincy Adams was the Secretary of State currently. Henry Clay was the Speaker of the House of Representatives. Henry Clay, receiving the least, was left out. However, as a leader in the House of Representatives, he had influence over the other members. Clay openly hated Jackson and there were rumors that Clay made a deal with Adams in exchange for his support. The House election declared John Quincy Adams president. Soon, he chose Henry Clay to fill the seat he left vacant, Secretary of State. Jackson was shocked and enraged. Although there was no inquiry of possible wrongdoing, Jackson accused Adams and Clay of making a "corrupt bargain." John Quincy Adams was a disappointment as president. Many of his goals created divisions like federal funds for internal improvement. Some states thought that taking federal funds would force them to follow certain rules. They felt this reduced their rights as independent states. Jackson took advantage of issues like this one to gather more support. More Jackson supporters found their way to seats in Congress. He was as a man of the people and said Adams could never understand the common man's concerns. John Quincy Adams ran against Andrew Jackson in the 1828 election. Personal attacks grew even more vicious, but Andrew Jackson appealed to many. He believed government was for the common man. He believed in strict reading of the law and limited internal improvements. He also believed in states' rights. Andrew Jackson easily won the 1828 election, winning both the popular vote and most electoral votes. Historians note the sectional nature of the voting. Support for Jackson was concentrated in South while Adams' support was mostly in the North. Jackson was so popular because he brought changes to the government. He also wanted to make sure the government was responsible for its actions. Jackson pushed settlement into the frontier. He supported the Indian Removal act. He also defended the spread of slavery. Though his support was heavier in the South, he was determined to keep a unified nation. The rise and presidency of Old Hickory is memorable to Americans today.
