Answer:

yes

Step-by-step explanation:

Using the Pythagorean Theorem, considering that the sum of the squares of the lengths of the two smaller sides is equals to the square of the length of the greater side, the triangle is a right triangle.

Pythagorean Theorem:

The Pythagorean Theorem states that for a right triangle, the sum of the squares of the lengths of the two smaller sides is equals to the square of the length of the greater side.

so it is a right triangle.

Answer:

18 is 30% of 60

Step-by-step explanation:

Try to line up percents % and the actual numbers they represent.

number : precent

       60  is 100%

        18  is x %

cross multiply

x·60 = 100·18

divide both sides by 60 to isolate x

x = ((100·18)/60

x = 30

Answer

2199

Step-by-step explanation:

the perimeter of the circle:

3.14 x 175 x 2= 1099

there are 2 inches in one foot

1099x12 = 13188

13188/6 inches = 2198

2198+1=2199 flowers

Answer:

The Scale Factor is 5.3

Step-by-step explanation:

Here's the reason why:

You are trying to make the rectangle much larger.

The 14yd by 6yd is trying to get to the 74.2yd by 31.8yd.

We need to remember the importance of length and width.

If 14 yards is our length then 74.2 yards is our length on the enlarged rectangle.

You must do 74.2/14 because we need to work backwords.

**You can't find something to multiply 14 by to get to 74.2 unless you do division.**

74.2/14 is 5.3

Now do the same with the width.

31.8/6

That is 5.3 as well.

Therefore the scale factor is 5.3

It would take about 3.4 seconds for the rocks to reach the ground.

An equation is an expression that shows the relationship between two or more numbers and variables.

Let h represent the height of the rock above the ground after t seconds. Given the equation:

h = -16t² + 186

The rock would reach the ground at h = 0, hence:

0 = -16t² + 186

16t² = 186

t = 3.4 seconds

It would take about 3.4 seconds for the rocks to reach the ground.

Answer:

2x^2 - 10x - 8.

Step-by-step explanation:

f(x) = 2(x - 1)(x + 4)    

= 2(x^2 - x - 4x - 4)

= 2(x^2 - 5x - 4)

= 2x^2 - 10x - 8.

Answer:

158

Step-by-step explanation:

The Formula for Area is: A = L * W

First lets start with the rechtangle:

A = L * W

A = 17 * 7 = 119

the area of the rechtangle is 119

Now the triangle the formula is a little diffrent but it is the same concept

A=hbb (Picture below, it wont let me write it out right)

2=6·13

2=39

The area of the triangle is 39

Now add the both areas

119 + 39 =

Answer:

406.08

Step-by-step explanation:

First FInd the area of the rectangle : which is short side * long side

-> 15*12=180m

Then find the area of the half circle, the formula of the area of a circle is [tex]\pi r^2[/tex]

here it's half a circle so it's [tex]\frac{\pi r^2}{2}[/tex] where r is 12

-> [tex]3.14\cdot \frac{\left(12\right)^2}{2}=226.08 m[/tex]

Finally just add the area of the rectangle with the area of the half circle

-> [tex]180+226.08=406.08 m[/tex]

Answer: 5.

Step-by-step explanation: Originally, Robert had 9 golf balls.  Then, he gave 4 to Tim, so that gives us an immediate clue that this is subtraction.  We can solve this problem by the following:

9 - 4 = ?

9 minus 4 equals 5, so we can fill in the question mark with our answer:

9 - 4 = 5.

Therefore, your answer is 5.
