Find the missing length indicated.
Help pls
2. none of the answers are correct
Answer:
400
Step-by-step explanation:
Use the right triangle altitude theorem.
All three triangles are similar, so we can write a proportion of corresponding side lengths.
Let y = x - 144
192/144 = y/192
144y = 192 * 192
144y = 36,864
y = 256
x = y + 144 = 256 + 144
x = 400
In 2010, there were 311 middle schools in Virginia. In 2016, there were 306. By what percent did the number of middle schools in Virginia decrease from 2010 to 2016?
Answer:1.6%
Step-by-step explanation: no of students in 2010=311
no of students in 2016=306
difference=311-306
=5
%decrease=5/311 x 100
Answer:
2
306 over 311 and x over 100 do the butterfly method then you have 30600 and 311x after that you divide 311 by 311 and 30600 by 311 and you have 1.6 but it says round to the nearest whole which is 2
Ms.Aluma is 165cm tall. She wants to find the square of her height In meters.
What is square of her height rounded to the nearest hundredth?
Height (m) x height (m) =height squared (m exponent 2)
Enter your answer in the box.
Answer:
2.72 cm2
Step-by-step explanation:
Height (m) x height (m) =height squared (m exponent 2)
The square of her height in meter² is 2.7225.
How to do decimal multiplication ?To multiply numbers with decimals one way is to multiply the given numbers without the decimal then in the obtained result put the decimal as many places before from the right as the sum of the digits after the digits which those decimal numbers had.
According to the given question Ms. Aluma is 165cm tall.
We know 165 cm is = (165/100)meter = 1.65meter.
As 1 meter is 100 centimeter.
∴ The square of her height is (1.65)² OR (1.65×1.65)m² which is
= 2.7225 m².

What is a quadratic equation?It is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
The given equation will be solved as below:-
x² + 8x − 30 = 0
Completing the square for the above equation.
( x + 4 )² - 16 - 30 = 0
( x + 4 )² = 46
x + 4 = ±√46
x = ±√46 - 4
Therefore, the solution to the quadratic equation by completing the square will be x = -4 ± √46. The correct option is A.

There is a 15% discount on all items in a store. You buy a $12 shirt and $45 jeans. What will be your total cost?
Answer:
The total cost of the shirt and Jean's together with a 15% discount would be $48.45.
Step-by-step explanation:
if you at 12 and 45 you get 57 now if you multiply that by .15 which would be 15% you would get $48.45.
Answer:
$48.45
Step-by-step explanation:
15% of $12= 1.80
15% of $45= 6.75
$12-$1.80= $10.2
$45- $6.75= $38.25
Now, add them both up:
$10.20+ $38.25= 48.45
Answer= $48.45

[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Properties of indices.
Here, we have to prove that, if the above exponential equation are equal or not., let's prove it
1.)L.H.S
a^12*a^4 = a^m*a^n ===> a^(m+n)
hence, a^(12+4) ===> a^(16)
2.) R.H.S
===> a^8*a^8 = a^(8+8) ==> a^(16)
since here, LHS = RHS
so both are equal.
