Need to find x, and measure of angle DEF
Step-by-step explanation:
(x+20)=9x
4x=20
x= 5°
because GEF AND DEG ARE EQUAL
THEN DEF= 2 * GEF
DEF = (9*5)*2=90
DEF= 90°
Consider all positive integers that are multiples of 10 and are less than or equal to 200. What fraction of those integers are multiples of 15?
A. 1/20
B. 3/20
C. 3/10
D. 2/5
E. 3/4
The fraction of those integers are multiples of 15 will be 3/10. Then the correct option is C.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
Consider all positive integers that are multiples of 10 and are less than or equal to 200.
Let the number of the positive integer that are multiples of 10 be x. Then the equation will be
10x ≤ 200
Then the value of the x will be
x ≤ 20
The set of numbers is given below.
Set = 20 {10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200}
The set which is divisible by 15 will be
Set = 6 {30, 6,0 90, 120, 150, 180}
Then the fraction of those integers are multiples of 15 will be
⇒ 6 / 20
⇒ 3/10
The fraction of those integers are multiples of 15 will be 3/10. Then the correct option is C.

Solve the quadratic inequality
4x^2-25<0
I hope it helps you ❤️❤️❤️❤️
The solution to the inequality, 4x^2 - 25 < 0 is determined as x < 5/2.
Solution to the inequality
The solution to the inequality is obtained by solving the inequality as shown below;
4x^2 - 25 < 0
add 25 to both sides of the equation;
4x² < 25
divide both sides by 4
x² < 25/4
take square root of both sides
x < 5/2
Thus, the solution to the inequality, 4x^2 - 25 < 0 is determined as x < 5/2.

A computer costs $800. It loses ¼ of its value every 2 years after it is purchased.
How much will the computer be worth in 6 years?
The computer will be worth $200.
Step-by-step explanation:
A quarter of $800 is $200, so the computer loses $200 dollars in value every two years. Since 6÷2 is 3, you multiple $200 by 3 to get $600. You then subtract $600 from $800 and get $200.
Answer: The value of the computer at time 0 is $800
The value of the computer at time 1 is $600
The value of the computer at time 2 is $450
The value of the computer at time 3 is $337.50
The value of the computer at time t is (n - 1) x 3/4

Leila needs to buy plastic spoons. Brand A has a box of 25 spoons for $1.97. Brand B has a box of 48 spoons for $2.98. Find the unit price for each brand. Then state which brand is the better buy based on the unit price. Round your answers to the nearest cent.
Answer:
The unit price is the price of a single unit.
To find it, you need to find the quotient between the total price and the number of objects you get for that price.
Brand A:
You get 25 spoons for $1.97
Then the unit price is:
unit price of brand A = $1.97/25 = $0.079
Brand B:
You get 48 spoons for $2.98
Then the unit price is:
unit price of brand B: $2.98/48 = $0.062
Here we can see that the unit price for brand B is smaller, then the better buy is brand B.

Step-by-step explanation:
These triangles can be proven congruent through AAS, or angle, angle, side. This means that two angles and one nonincluded side are congruent. Two sides are marked as congruent through a tick mark, and one angle pair is marked by one arc on each angle. We also know that the middle angles, that are connected, are congruent because they are vertical angles. Therefore, they are congruent, which can be proven by AAS.
PLEASE I need help on these 4 problems you don’t have to do them all but if you can at least do one of them TYSM
Answer:
For right angle triangle,
we use Pythagoras theorem that is:
[tex]c^{2} =a^{2} +b^{2}[/tex]
c = [tex]\sqrt{a^{2} +b^{2} }[/tex]
For question 1:
c = ?
a = 40
b = 9
putting them in formula,
c = [tex]\sqrt{40^{2} + 9^{2} }[/tex]
c = 41
For question 2:
c = ?
a = 12
b = 13
putting them in formula,
c = [tex]\sqrt{12^{2} + 13^{2} }[/tex]
c = approximately 17.69181
For question 3:
c = 35
a = 20
b = ?
putting them in formula,
[tex]c^{2} =a^{2} +b^{2}[/tex]
[tex]35^{2} = 20^{2} + b^{2}[/tex]
1225 = 400 + [tex]b^{2}[/tex]
[tex]b^{2}[/tex] = 1225 - 400
[tex]b^{2}[/tex] = 825
[tex]\sqrt{b^{2} } = \sqrt{825}[/tex]
b = 5 [tex]\sqrt{33}[/tex]
For question 4:
c = 37
a = 20
b = ?
putting them in formula,
[tex]c^{2} =a^{2} +b^{2}[/tex]
[tex]37^{2} = 20^{2} + b^{2}[/tex]
1369 = 400 + [tex]b^{2}[/tex]
[tex]b^{2}[/tex] = 1369 - 400
[tex]b^{2}[/tex] = 969
Taking square root on both sides
b = 31.12
Hope it helps.

a. How far is the spot on the beach from the parking lot?
b. How far will he have to walk from the parking lot to get to the refreshment stand?
Show work please.
The altitude of the right triangle is the geometric mean of the 2 parts of the side it separates.
a. The answer would be sqrt(18*32)=24
The question to the second question can be answered by using the Pythagorean theorem.
32^2+24^2=1600=40^2
b. The answer would be sqrt40^2=40
The beach, the parking lot and the refreshment stand are illustrations of similar triangles.
The distance between the spot and the parking lot is 24 mThe distance between the refreshment stand and the parking lot is 40 m(a) The distance between the spot and the parking lot
Represent this distance with d.
So, the equivalent ratio is:
[tex]\mathbf{32:d = d : 18}[/tex]
Express as fractions
[tex]\mathbf{\frac {32}d = \frac{d}{ 18}}[/tex]
Cross multiply
[tex]\mathbf{d \times d = 32 \times 18}[/tex]
[tex]\mathbf{d^2 = 576}[/tex]
Take square roots
[tex]\mathbf{d = 24}[/tex]
Hence, the distance between the spot and the parking lot is 24 m
(b) The distance between the refreshment stand and the parking lot
Represent this distance with d.
Using Pythagoras theorem we have:
[tex]\mathbf{d^2 = 32^2 + 24^2}[/tex]
[tex]\mathbf{d^2 = 1600}[/tex]
Take square roots
[tex]\mathbf{d = 40}[/tex]
Hence, the distance between the refreshment stand and the parking lot is 40 m
