So, by converse of Pythagoras theorem given side lengths form a right triangle
Answer:
Right
Step-by-step explanation:
The side lengths are 5, 5√3, and 10. This tells me this is a 30° 60° 90° triangle. In a 30° 60° 90° triangle, the relationship between the side lengths are a, a√3, and 2a. a represents the side length of the first leg of the triangle. a√3 represents the second side length, which is the first leg's side length multiplied by √3. Finally, 2a represents the hypotenuse which is two times bigger than the first leg's side length.

Order the numbers from least to greatest. Put the lowest number on the left. 11/12 , 9/8 , 1/3 ,
Answer:
1/3,11/12,9/8
Step-by-step explanation:
Hi! Let's start off with creating common denominators for all three of these fractions.
The LCM (least common multiple) of these three denominators is 24, which means that the three numbers you see at the bottom of the fraction (12, 8, and 3) all in some way have a number that will cause it to multiply to 24, and will make it much more easier to determine the fraction.
1) Change all of the denominators into 24 by multiplying the right number
11/12×2/2=>22/24
9/8×3/3=>27/24
1/3×8/8=>8/24
So now I want you to imagine that the denominators don't exist. From there, you can sort out the fractions from least to greatest! Hope you understood this :)

Which expression is NOT equivalent to 24 + 6x?
A. 2(3x + 12)
B. 28 + 4x – 4 + 2x
C. 5x + 7 + x + 17
D. 3(8 + 3x)
Answer:
D
the answer is D because when you multiply 3(8 + 3x), it will give you 24+9x
3(8 + 3x) is not equivalent to 24 + 6x.
Option D expression is not equivalent to 24 + 6x.
What is an expression?An expression or algebraic expression is any mathematical statement which consists of numbers, variables and an arithmetic operation between them.
According to the question
Expression is NOT equivalent to 24 + 6x
A . 2(3x + 12)
= 2(3x) + 2(12)
= 6x + 24
= 24 + 6x
B. 28 + 4x – 4 + 2x
= (28 - 4) + (4x + 2x)
= 24 + 6x
C. 5x + 7 + x + 17
= (5x + x) + (7 + 17)
= 6x + 24
= 24 + 6x
D. 3(8 + 3x)
= 3(8x) + 3(3x)
= 24 + 9x
Hence, Option D is not equivalent to 24 + 6x.
3(8 + 3x) is not equivalent to 24 + 6x.

Mary is making a birthday cake to surprise her mom. She needs 3 1/2 cups of flour, but she only has 1/3 cup. How much more flour does she need?
Answer:
3 1/6 cups more
Step-by-step explanation:
Answer:
3 1/2 = 7/2 (write as a mixed number)
7/2 - 1/3 = ?( you need more flour, so subtract what you have from what you need. to subtract you need to find the least common denominator)
21/6 - 2/6
19/6 cups of flour is what you need.
or 3 1/6 cup if it needs to be converted back into a mixed fraction

Jordan drives for three hours at an average of 60 miles per hour what is the distance in miles he drives during that time
Answer:
180 miles
Step-by-step explanation:
1. Use the drt (distance, rate, time) triangle (shown in the picture) to determine which operation you need to do.
You are given t (time) and r (rate), but you don't have d (distance). What you do is cover up the missing variable d (distance). Since you are left with t and r (time and rate), which are side by side, you multiply the numbers.
2. Plug in the numbers for t and r. Then multiply.
t=3
r=60
3 x 60 = 180 miles
What is the area of the region bounded by the lines x= 1 and y= 0 and the curve y=xe^x^2?
Answer:
A = 0.859
Step-by-step explanation:
We want to find the area of the region bounded by the lines x = 1 and y = 0 and the curve y = xe^(x²).
At y = 0, let's find x;
0 = xe^(x²)
Solving this leads to no solution because x is infinity. Thus we can say lower bound is x = 0.
So our upper band is x = 1
Thus,lets find the area;
A = ∫xe(x²) dx between 1 and 0
A = (e^(x²))/2 between 1 and 0
A = ((e¹)/2) - (e^(0))/2)
A = 1.359 - 0.5
A = 0.859

3 There are 5 times as many boys as girls in a school.
Together the school has 810 pupils.
How many boys are there?
Answer:
Number of boys = 675
Step-by-step explanation:
Given that:
There are 5 times as many boys as girls in a school.
Number of pupils in school = 810
Let,
x be the number of girls
y be the number of boys
According to given statement;
x+y=810 Eqn 1
y = 5x Eqn 2
Putting y=5x in the Eqn 1
x+5x=810
6x=810
Dividing both sides by 6
[tex]\frac{6x}{6}=\frac{810}{6}\\x=135[/tex]
Putting x=135 in Eqn 2
y = 5(135)
y = 675
Hence,
Number of boys = 675
