Answer:

√39

Step-by-step explanation:

This triangle is a right triangle, we can use the Pythagoras Theorem.

The hypotenuse or the slanted part of the triangle is c, while the other two are b and a, doesn't matter the order.

In this picture we know what c is and what a (or b, doesn't matter, like I stated before ;w;) is.

a = 5

c = 8

b = x

a^2 + b^2 = c^2

5^2 + x^2 = 8^2

25 + x^2 = 64

x^2 = 64 - 25

x^2 = 39

√x^2 = √39

x = √39

  • [Right Triangles Only] Pythagorean Theorem: a² + b² = c²

Step-by-step explanation:

<u>Step 1: Identify</u>

Leg <em>a</em> = <em>x</em>

Leg <em>b</em> = 5

Hypotenuse <em>c</em> = 8

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute [PT]:                     x² + 5² = 8²
  2. Isolate <em>x</em> term:                       x² = 8² - 5²
  3. Exponents:                            x² = 64 - 25
  4. Subtract:                               x² = 39
  5. Isolate <em>x</em>:                               x = √39

iren2701 [21]

Answer:195 cans

Step-by-step explanation:

y=-63x+825

y=number of cans

x=number of days

When number of days is 10 that is x=10

y=-63x+825

y=-63x10+825

y=-630+825

y=195

What is the diameter of this circle if the circumference is 30 x inches?
ch4aika [34]

Answer:

<h2>10 inches</h2>

Step-by-step explanation:

Given the circumference= 30 in

we know that the formula for circumference is

C= 2\pi r

30= 2*3.142*r\\\\r= \frac{30}{2*3.142} \\\r= \frac{30}{6.248}\\\r= 4.77 in

The diameter is 2*r= 4.77*2=9.55 in

Approximately the diameter is 10 inches

your teacher is giving you a test worth 100 points that contains 40 questions. there are 2point questions on the test. how many
kykrilka [37]
100 = 2t + 4f 
40= t + f
-----------
get t or f by itself first.

f = 40 - t : Then substitute it back into for f in the other equation
100 = 2t + 4f 
100= 2t +4(40-t) 
100= 2t + 160 - 4t
100 = -2t + 160
-160           -160

<u>-60 </u>= <u>-2t
</u>-2        -2

t = 30 (Then plug this into either equation to solve for f)

Therefore,
t = 30 questions
f = 10 questions
