Step-by-step explanation:

Number 1: He needs 5x3 to get 15 balloons, but since he need more than provided, he needs one more pack.

Number 2: He played 2 rounds, and each round got 4 points, 4x2=8.

Number 4: If she had 8x8=64, and subtracted 10, she has 54.

Number 6: So you should make the fractions improper fractions, (fractions that have a numerator thats more than the denominator) so 2 1/4 = 9/4 and 3 1/4 = 13/4 and then multiply 13 x 9= 117 and then 4x4= 16 so you have 117/16 and then when you simplify it you get: 7 5/16

A map has a scale of 1 cm : 30 km. If 2 cities are 4.7 cm apart on the map, how far apart are they in reality?

Answers

Answer:

141 Km apart.

Step-by-step explanation:

so if each 1 cm is equivalent to 30 km, we would take the 4.7 and multiply it by the 30 to get the true value.

the true value would come out to be 141 km apart.

Please mark this as brainlest.

141 miles away.

Explanation? Common sense, no?

We are given the unit rate, so we can convert it easily.

1cm = 30km, so, multiply it by 4.7 as there are 4.7cm that are present.

30km x 4.7 = 141km in real life.

Which is the best use for the converse of the Pythagorean theorem?
to show that all triangles have a right angle
to prove that a triangle is equilateral
to determine from the side lengths if a triangle is a right triangle
to find the length of an unknown side of a right triangle

Answers

Answer:

here you go

Step-by-step explanation:

The converse of the Pythagorean Theorem tells us that by comparing the sum of the squares of two sides of a triangle to the square of its third side, we can determine whether that triangle is an acute, right, or obtuse.

To determine from the side lengths if a triangle is a right triangle. Therefore, the correct answer is option C.

What is the Pythagoras theorem?

The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.

The converse of Pythagoras theorem states that “If the square of a side is equal to the sum of the square of the other two sides, then triangle must be right angle triangle”.

By comparing the sum of the squares of two sides of a triangle to the square of its third side, we can determine whether that triangle is an acute, right, or obtuse.

Therefore, option C is the correct answer.

64 is 4 times the difference between Sarah's age, a, and 44. Assume Sarah is older than 44.

Write an equation to determine Sarah's age (a).

Find Sarah's age.

Answers

Answer:64/4+44=a

Sarah is 60 years old

Step-by-step explanation: 64/4 =16. 44+16=60

Multiply this difference by 4, and you get 64 as the result. So:

64 = 4(a - 44)

Now you need to balance the equation. Do the same operation to both sides. To begin, divide both sides by 4.

64/4 = 4(a - 44)/4 becomes

16 = a - 44 To get variables on one side and numerals on the other, add 44 to each side.

16 + 44 = a

60 = a. Sarah is 60 years old.

y = x² - 3

y = 0² - 3

y = 0 - 3

y = -3

(0, -3)

y = x² - 3

y = 1² - 3

y = 1

y = -2

(1, -2)

y = x² - 3

y = 2² - 3

y = 4 - 3

y = 1

(2, 1)

y = x² - 3

y = 3² - 3

y = 9 - 3

y = 6

. A right triangle is drawn inside a sphere, and the hypotenuse is 12 cm. What is the radius of the sphere? Round your final answer to the nearest hundredth.

Answers

Answer:

Step-by-step explanation:

The required measure of the radius of the sphere is given as 6 cm.

What is the triangle?

The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°

Here,
A right triangle is drawn inside a sphere, and the hypotenuse is 12 cm.
As we know, for a right triangle inscribed in a circle, the hypotenuse represents the circle's diameter,
hypotenuse = diameter
12 = diameter
radius = diameter / 2
radius = 12/2
radius = 6 cm

Thus, the required measure of the radius of the sphere is given as 6 cm.

A server makes $200 a week working at a local restaurant. The server saves 35% of the
$200 weekly earnings each week for 4 weeks.If the server saves 7/8 of the 5th week’s
$200 earnings, how much money will the server have saved in total after the 5 weeks?

Answers

It would have saved 445$
Explanation: because for 4 weeks he saved 35% of 200$ which would be 70 and 70+70+70+70 280$ and the he saved 175$ on the fifth week because 7/8 of 200 is 175 so 280+175 is 445

What are the first two steps of drawing a triangle that has all side lengths equal to 12 centimeters?
Select from the drop-down menus to correctly complete the statements.

Draw a segment (6, 12, 24) centimeters long. Then from one endpoint, draw a (30, 60, 90) ° angle.

Answers

Answer:

All the sides should be 4 cm.

Step-by-step explanation:

The first triangle rule is the two sides should be greater than the longest side when added together.

For example- 4+4=8 which is bigger than 4

12 divided by 3 is 4.

Hope this helps.

Answer:

Step-by-step explanation:

Remark

All triangles have 180 degrees.

In order that all sides be 12cm long, you need to draw a base line that goes on for more than 12 cm.

Mark off the (using a ruler) a line that is 12 cm from one of the line written about.

From that same endpoint, draw an angle that is 60o. Draw a line going 60 degrees from your first line.

=============

Just to finish the triangle, go to the other end of the 12 cm line. Draw another 60 degree angle. Make it so that it will intersect the second line you drew.\
