erma4kov [3.2K]

Answer:

30 people

Step-by-step explanation:

100 people to the survey. And the question is practically asking how many people are left. So we have to subtract 60 from 100. And then subtract 10.

1.) 100 - 60 = 40

2.) 40 - 10 = 30

Hope this helps you out! : )

A fountain in the park has two circular pools that are the same size. What is the total area of the pools if the radius is 3 yar
mihalych1998 [28]

Answer:

56.6 square yards.

Step-by-step explanation:

Given:

A fountain in the park has two circular pools that are the same size.

<u>Question asked:</u>

What is the total area of the pools if the radius is 3 yards ?

<u>Solution:</u>

First of all we will calculate the area of a circular pool.

As we know:

Area\ of\ circle=\pi r^{2}

                       =\frac{22}{7} \times(3)^{2} \\ \\ =\frac{22}{7}\times9\\ \\ =\frac{198}{7} \\ \\ =28.28\ square\ yards

Area of circular pool nearest tenth = 28.3 square yards

Now, as given that both pools are of same size.

Total area of the pools = 28.3 square yards + 28.3 square yards

                                      = 56.6 square yards.

Thus, the total area of the pools are 56.6 square yards.

If j=h and k=m then which expression represents the value of g
Colt1911 [192]

Answer:

Step-by-step explanation:

as given j=h and k=m then which expression for g is

as from attached image , we can see that its look like two right angle triangle

so from lower triangle we apply the pythagorean theorem .

which state that sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.

so small triangle ΔEBD

h² +k²= g²       ---------------(1)

now from big triangle ΔABC

(j + h)² +(m + h)² =f²---------(2)

given j=h and k=m so from equation-2 we can find ,

(h + h)² +(k+ k)² =f²

(2h)² +(2k)²=f²

4h²+ 4k²= f²

4(h²+k²)= f² ----------(3)

now from equation 1 and 3 we can obtained .

4×g² =f²

take square root both side we get,

2×g=f

so g=f/2----- Answer

Saige's spaceship traveled 588588588 kilometers (\text{km})(km)left parenthesis, start text, k, m, end text, right parenthesis i
lesantik [10]

Answer:

A is proportional

B and C are <u>NOT</u> proportional

Step-by-step explanation:

First, simplify 588 and 60:

<u>588 divided by 6</u>

60 divided by 6

= <u>98</u>

  10

Simplify them again by dividing them both by 2

= <u>49</u>

   5

Let's look at A:

441 and 45

Simplify by dividing by 9

= <u>49</u>

   5

It's pretty obvious that A is <u>proportional</u> because the simplified values are exactly the same.

Next, let's check B:

215  and 25

Simplify by dividing by 5

= <u>43</u>

   5

Now that its simplified you can compare

<u>43</u>   is smaller than <u>49</u>

5                               5

B is <u>not proportional</u>

<u />

Finally, let's check C:

649 and 110

Simplify by dividing by 11

= <u>51</u>

  10

Make <u>51</u> and <u>49</u> have the same denominator so we can compare them

          10         5

<u>51</u> can stay the same because 5 times 2 equals 10

10

<u>49 times 2</u>

5 times 2

=  <u>98</u>

    10

Now that the denominators are the same we can compare

<u>51</u> is much smaller than <u>98</u>

10                                     10

Therefore, C is also <u>not proportional.</u>

<u />

Hope that helps :D
