23
Step-by-step explanation
16/9=width/height
20 is the width of the computer monitor so you would put width as 20
20/x then you would cross multiply to find the height which is x.
20 x 9=180
Then you would divide 180 by 16.
180/16=11.25
So now you have the width and the height 20/11.25=width/height
Then you do the pythagorean theorem a^2+b^2=c^2=20^2+11.25^2=526.5.6^2.Then you would round you answer to get 526.6 Then you would find the square root of 526.6 which is 22.9. Then you would round the answer to get 23.
Solve: 3(2x-5) +2x+3=1
Answer:
Step-by-step explanation:
3(2x-5) +2x+3=1 Distribute the 3
6x-15+2x+3=1 Combine like terms
8x-12=1 Add 12 to 1
8x=-12 Divide by 8
x=13/8
Answer:
x = [tex]\frac{13}{8}[/tex]
Step-by-step explanation:
3(2x - 5) + 2x + 3 = 1 ← distribute parenthesis and simplify left side
6x - 15 + 2x + 3 = 1
8x - 12 = 1 ( add 12 to both sides )
8x = 13 ( divide both sides by 8 )
x = [tex]\frac{13}{8}[/tex]

Subtraction is a mathematical operation. The best policy to buy is a 20-year term policy.
What is subtraction?Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.
Since we want the policy to last till the younger child is 22 years. And the present age of the younger child is 3 years. Therefore, the period for which the policy must work is 19 years (22-3).
Therefore, the best policy to buy is a 20-year term policy.

Are my answers correct, if not can you explain why?
Answer:
the first one would actually negative because to the left is negative and to the right is positive. and you got the y wrong, that is actually a 2 because you dont include the line you count from, making it (-3,2).
the second one would be perfectly correct.
the third one is actually (-2,-2) and i have no idea how you got that answer, how you would count it 0, its to the left -2 and down -2.
the fourth one, would be actually (-6,-1), remember, a point goes (x,y)

4 less than four times a number is equal to three times the same number plus 1
Answer:
5Step-by-step explanation:
let x be the number we are looking for
Mathematically the statement “4 less than four times a number”
means 4x - 4
Mathematically the statement “three times the same number plus 1”
means 3x + 1
Statement 1 is equal to statement 2
means 4x - 4 = 3x + 1
We got an equation and we need to solve it :
4x - 4 = 3x + 1
⇔ 4x - 3x = 1 + 4
⇔ x = 5
rewrite 14x − 4y = 13 in slope-intercept form.
Answer:
y=7/2 x − 13/4
Step-by-step explanation:
Answer:
y=(14x-13)÷4
Step-by-step explanation:
1. Subtract 14x from both sides

best fuel efficiency? Why?
IT'S A CONSTRUCTED RESPONSE!!!
PLEASE SOMEONE ANSWER ME!!!! :/
In order to calculate efficiency
Range ÷ FuelOption A
528 ÷ 24 = 22 mi/gal
Option B
690 ÷ 30 = 23 mi/gal
Option C
840 ÷ 42 = 20 mi/gal
Option B, gives the best fuel efficiency because the car can travel further using 1 gallons of fuel than others.

Finding Angles (Level 1)
Delta Math
#highschool
Answer:
∠ E = 43°
Step-by-step explanation:
∠ BGE and ∠ FHC are alternate exterior angles and are congruent , then
∠ BGE = 119°
the sum of the 3 angles in Δ BGE = 180°, that is
∠ E + 18° + 119° = 180°
∠ E + 137° = 180° ( subtract 137° from both sides )
∠ E = 43°
Answer:
43
Step-by-step explanation:
so, it gives your angle FHC and angle B. remember B because it is important a little later, so you know that angle FHC=119. and if you remember learning congruent angles, you would know that angle HGA also equals 119 because they are corrisponding angles. so, you know they are corrisponding, how does that help you? well, if you remember learning that vertical angles are congruent, then it tells you that FHC=HGA, also meaning that HGA=119. and remember how you know that angle B=18? this also helps because you know that a triangles angles always equal 180, so you simply add 119+18=137 degrees, and you want the unknown angle being m<E and which to find you simply subtract 180-137=43 so, M<E=43 because subtracting 180-137 gives you the unknown.

As you can see, the area of the scarf is equal to the area of the rectangle minus the area of the 2 semi-circles (which form a circle)
Now, we calculate the area of the rectangle : 28 x 15 = 420 in2
The diameter of the circle is 15in -> The radius = 15 : 2 = 7.5in.
We now find the area of the 2 semi-circles : 7.5 x 7.5 x 3.14 = 176.625 in2
So, the area of the scarf is : 420 - 176.625 = 243.375 in2

You roll a 6-sided die two times.
What is the probability of rolling a number less than 4 and then rolling a number less than 47
Write your answer as a percentage.
Answer:
as a non percent 3/6 or 50%
Step-by-step explanation:
A number less than 4 would be 1,2 and 3 so you have 3/6 die chance
Vs. 1,2,3,4,5,6 which are all under 47 so rolling a number like that would be 100% or 6/6
which best explaines what determines whether a number is irrational
Irrational number can be written as decimal number that, neither a terminating decimal or repeating decimal. Thus, the option D is the correct option, which is a number that can be written as a decimal that neither repeats nor terminates.
What is a irrational number?
Irrational numbers are the number which is the real number but not the rational number(a/b).The irrational numbers can not be represents in the fractional form.
Irrational numbers are written in the form of root of a number such as,
, , etc.
Irrational number can be written as decimal number that, neither a terminating decimal or repeating decimal.
Lets check all the given options as,
A) A number that can be written as a decimal that repeats and does not terminate- Irrational numbers is a decimal which does not repeats. Thus this is not correct option.
B) A number that can be written as a decimal that terminates and does not repeat- Irrational numbers is a decimal which does not terminate. Thus this is not correct option.
C) A number that can be written as a square root that does not result in a whole number-This does not explain the property of irrational number. Thus this is not correct option.
D) A number that can be written as a decimal that neither repeats nor terminates-Irrational number can be written as decimal number that, neither a terminating decimal or repeating decimal. Thus this is the correct option.
Hence, A number that can be written as a decimal that neither repeats nor terminates the option D is the correct option.

Do the same thing with q. Add p and q the way 2 vectors would be added together. So AT is 1/2(p + q)
Starting at A draw 1/2 p. Maintaining the same angle for q, draw 1/2 q at the end of 1/2 p. Hence the answer is vector(AT ) = (1/2 p + 1/2 q)
