The pair of figures to the right are similar. The area of one figure is given. Find the area of the other figure to the nearest whole number.
Area of larger triangle = 195ft^2
The area of the smaller triangle is ? ft^2. (Round to the nearest whole number as needed.)
Answer:
70 ft²
Step-by-step explanation:
ratio of their same side is 6/10 = 3/5
area ratio will be square of this so,
are of small traingle will be,
195 × (3/5)²= 195 × 9/25= 70.2
Elisabeth reads 15 of her book in 112 hours. Elisabeth continues to read at this pace. How long does it take Elisabeth to read 3/4 of the book?
Enter your answer as a mixed number in the simplest form by filling in the boxes.
The number of hours it takes Elisabeth to read 3/4 of the book is; 5³/₅ hours
What are mixed numbers?We are told that she reads 15 of her books in 112 hours.
Thus, number of hours to read one book is;
112/15 hours per book
Therefore, number of hours to read ³/₄ of the book is;
³/₄ * ¹¹²/₁₅ = 28/5
As a mixed number is 5³/₅ hours per book

I need help with 13 on both pictures. The first picture is the answer and the second picture is the question not getting the answer at all
Problem 13
If we want to multiply (x^3-3x^2+2x) with (x^3-2x^2+x), then we can set up a diagram shown below. The terms are along the outside. The stuff inside is the result of multiplying each pair of outer terms.
Example: x^3 times x^3 = x^6 in the top left cornerAnother example: 2x times x = 2x^2 in the bottom right corner.This is known as the box method to keep track of all the terms multiplied.
Once the table is filled out, we add up each term inside the boxes. Combine like terms if possible. Notice that I color-coded the like terms (eg: the x^3 terms are in green boxes).
The final answer is x^6 - 5x^5 + 9x^4 - 7x^3 + 2x^2
Find point D on AB that is 3/4 of the distance from A to B
Derived from the Pythagorean Theorem, the distance formula is used to find the distance between two points in the plane. The Pythagorean Theorem, a2+b2=c2 a 2 + b 2 = c 2 , is based on a right triangle where a and b are the lengths of the legs adjacent to the right angle, and c is the length of the hypotenuse.
a2+b2=c2 a 2 + b 2 = c 2 ,

6p^2 = 8p + 3
No real solutions
2 irrational solutions
1 rational solution
2 rational solutions
Answer:
2 irrational solutions.
Step-by-step explanation:
6p^2 = 8p + 3
0 = -6p^2 + 8p + 3
The roots are:
p = (2/3) - (8.5)^(1/2)/3, and
p = (2/3) + (8.5)^(1/2)/3
These are irrational numbers.
There are 2 irrational solutions.

Please help!!!!! Show work too, I'm having a hard time understanding how to solve this! (30 points!)
Answer:
y = -1/3
Step-by-step explanation:
Isosceles trapezoids have legs that are the same length
AB = CD
7y-4 = 4y-5
Subtract 4y from each side
7y-4-4y = 4y-5-4y
3y -4 = -5
Add 4 to each side
3y -4+4 = -5+4
3y = -1
Divide by 3
3y/3 = -1/3
y = -1/3
Step-by-step explanation:
an isoceles trapezoid means that both legs (the sides left and right) are of equal length.
the length of the baseline does not matter at all (I guess, it is given here to confuse us or for follow up questions).
so, we know that AB = CD.
and therefore
7y - 4 = 8y - 18
-4 = y - 18
14 = y
The ratio of boys to girls at a camp is 4:5. If there are 75 girls, how many boys are there? I NEED AN ANSWER ASAP PLEASE
Answer:

The sum of two one numbers, one of which is one thirds of the other, is 60. Find the smaller number
Answer:
x = 15
(y = 45)
Step-by-step explanation:
x + y = 60
x = y/3
y/3 + y = 60 /*3
y + 3y = 180
4y = 180 /÷4
y = 45
x = y/3 = 45/3 = 15
Answer:
15 smaller The other 45
Step-by-step explanation:
X= big
1/3(x) = small
x+1/3(x) = 60
Multiply both sides by 3 to eliminate the fraction
3x+x = 180
4x=180
x= 45 (big=45)
60-45= 15 (small = 15)
45/3=15

Which expression is equivalent to -6(-2/3+2x)?
plss hurry im timed
-4-12x
-4+2x
4-12x
4÷12x
Answer:
4 - 12x
Step-by-step explanation:
-6(-2/3 + 2x)
we can distribute by multiplying -6 by whats inside of the parenthesis ( -2/3 and 2x )
-6 * -2/3 = 4
-6 * 2x = -12x
4 - 12x would be the equivalent expression
Given expression to us is ,
→ -6( -2/3 +2x)
Simplify by multiplying each terms inside the brackets by -6 .
→ -6*-2/3 + 2x*(-6)
Simplify,
→ 4 -12x
Hence option 3 is correct .
I hope this helps .
