Answer:

Step-by-step explanation:

let's place 9 in place of p and 4 in place of q. I will use a star in place of that symbol for the sake of my convenience having to look for it, apologies.

$9 \star 4 = 9^2-4^2 = 81-16 = 65$

If the number of visitors on Friday, Saturday, and Sunday is x, x + 500, and x + 250. Then the total number of visitors will be 3x + 750.

<h3>What is Algebra?</h3>

Algebra is the study of mathematical symbols, and the rule is the manipulation of those symbols.

Tanisha's website had x visitors on Friday.

On Saturday, it had 500 more visitors than it did on Friday. That is x + 500

The total number of visitors on Friday and Saturday was twice the number on Sunday. That is (2x + 500)/2

Then the total number of the visitors will be

→ Friday + Saturday + Sunday

Then we have

$\rm \rightarrow x + x + 500 + \dfrac{2x + 500}{2}\\\\\rightarrow 2x + 500 + x + 250\\\\\rightarrow 3x + 750$

3/28 of the animals are birds. 4/15 are birds of prey. What fraction of the animals are birds of prey.

vova2212 [387]

Let's call animals "a", and birds "b", birds of prey, "p"

so, b= $\frac{3}{28} a$

and p= $\frac{4}{15} b$
what;s the relation of p to a?

we substitude b into the last one:

and p= $\frac{4}{15}* \frac{3}{28} a$
so:
p= $\frac{4*3}{15*28} a$

p= $\frac{4*1}{5*28} a$

p= $\frac{1*1}{5*7} a$

p= $\frac{1*1}{35} a$

which is the answer!

<h3>Solution(s):</h3>

<u>1)</u><u> What distance did a car travel that went 70 mph for 6 hours?</u>

Given:

70 miles = 1 hour

<u>Multiply the RHS by 6 to see what distance was covered by the car in 6 hours.</u>

70 miles = 1 hour
=> 70 x 6 miles = 6 hours
=> 420 miles = 6 hours

The car traveled 420 miles in 6 hours.

<u>2)</u><u> What is the perimeter of a rectangle with a length of 7 cm and a width of 4 cm?</u>

Given:

Length: 7 cm
Breadth: 4 cm

Formula to find perimeter: 2(L) + 2(B)

<u>Substitute the values into the formula to find the perimeter.</u>

2(L) + 2(B)
=> 2(7) + 2(4)
=> 14 + 8
=> 22 cm

The perimeter of the rectangle is 22 cm.
