1. If RU = 16, UT = 20, and SR = 16, what is the perimeter of SUT?
Figure:
Please answer ASAP!
Answers
Answer:
72
Step-by-step explanation:
If SR and RU have the same length, a right angle, and a shared side, we know that they are congruent triangles using SAS (Side Angle Side). Our equation to find the perimeter would be SR + RU + UT + TS or 16 + 16 + 20 + 20(using our knowledge of the congruent triangles) = 72.
The Perimeter of SUT is 72 units.
What is Pythagoras theorem?According to the Pythagoras theorem, the square of the hypotenuse of a triangle, which has a straight angle of 90 degrees, equals the sum of the squares of the other two sides.
Given:
RU = 16, UT = 20, and SR = 16
Now, Using Pythagoras theorem
UT² = RT² + RU²
20²= RT² + 16²
RT² = 400- 256
RT² = 144
RT= 12
And, ST=20
Now, Perimeter of SUT
= 16 + 16 + 20 +20
= 72

Write the equation of the line fully simplified slope-intercept form.
Answers
Answer:
Step-by-step explanation:
y = mx + b <-- slope intercept form
Looking at the line from point (0,-5) to (3,0)
The slope (mx), rise over run
Rises 5 (in the positive direction, up) and runs 3 (in the positive direction, right)
the slope being 5/3
Then the b being your y-intercept
-5 will be your b because the line crosses the y axis at (0,-5) but the y-intercept is -5
Overall: y = [tex]\frac{5}{3}[/tex] x + (-5)
or
y = 5/3 x - 5

Grant has $58 in a savings account. He plans on depositing $30 into the
account each month and not taking any money out of the account. Which
function rule will give the total amount T that he has in the account
after n months?
Answers
Answer
I believe it is the first answer
Step-by-step explanation:
You would have to multiply 30 by however many months he deposits money to find how much he has in he account at that time
Hope this helps
The function rule of the total amount T in the account after n months is
T = 30n + 58.
Option A is the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Amount in the account = $58
Amount deposited each month = $30
The total amount after n months.
T = 58 + 30n
Thus,
The T = 30n + 58 is the total amount in the account after n months.

A toy rocket is launched vertically upward from a 8 foot platform with an
initial velocity of 120 feet per second. Its height h at time t seconds after
launch is given by the equation h(t) = -16t^2 + 120t + 8. How many seconds
until the rocket is 40 feet? (There may be more than one answer)
A) 0.28
B) 0.94
C) 3.17
D) 4.62
E) 5.98
F) 6.44
G) 7.22
H) 8.17
Answers
Answer:
We get t= 7.22 and t=0.28
The correct options are Option A and Option G
Step-by-step explanation:
The height h of toy rocket at time t seconds after launch is given by the equation [tex]h(t) = -16t^2 + 120t + 8[/tex]
We need to find how many seconds until the rocket is 40 feet?
We are given height of rocket h(t) = 40 feet
and we need to find time t
Using the equation [tex]h(t) = -16t^2 + 120t + 8[/tex] we can find time t
We have h(t)=40
[tex]h(t) = -16t^2 + 120t + 8\\Put\:h(t)=40\\40= -16t^2 + 120t + 8\\16t^2-120t-8+40=0\\16t^2-120t+32=0[/tex]
Now, we will solve the quadratic equation using quadratic formula: [tex]t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
We have a =16, b=-120 and c=32
Putting values and finding t
[tex]t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\t=\frac{-(-120)\pm\sqrt{(-120)^2-4(16)(32)}}{2(16)}\\t=\frac{120\pm\sqrt{14400-2048}}{32}\\t=\frac{120\pm\sqrt{12352}}{32}\\t=\frac{120\pm111.12}{32}\\t=\frac{120+111.12}{32}, t=\frac{120-111.12}{32}\\t=7.22\:,\:t=0.28[/tex]
So, we get t= 7.22 and t=0.28

Each of the squares has trinomials that factor. x^2 - 14x + 49 = (x - 7)^2
When you take the square root (to get the side length) you get x - 7. So the length of each square is x - 7) = 0;..........x=7 That's the answer to a.
The answer to b is the same. The width =7
It's a square both sides have to be equal.
The length of the rectangle when the two squares are put together is 7 +7 = 14.

Rewrite the sum of 75+18 as a product of a number and another sum
Answers
Answer:
(2)(9) + 75 = 75+18
Step-by-step explanation:
(2)(9) + 75 = 75+18
The expression written as a product of a number and another sum is 3(25 + 8)
Given the expression 75 + 18, we are to write as a product of a number and another sum.
First we need to find the GCF of 75 and 18
75 = 3 * 25
18 = 3 * 6
Since 3 is common to both D+GCF, we can factor it out from the expression to have:
75 + 18 = 3(25 + 8)
Hence the expression written as a product of a number and another sum is 3(25 + 8)

Answers
Answer:
"less than 90°."
Step-by-step explanation:
This is because an obtuse triangle can be defined as "An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles." Therefore, there can only be ONE obtuse angle. Therefore, with the obtuse angle being at vertex B, there cannot be another one at vertex A.

A blueprint for a house shows the height of the house to be 3 1/4 inches. The actual house is 21 1/3 feet tall. What is the unit rate in feet per inch
feet per inch?
Answers
Answer:
6[tex]\frac{22}{39}[/tex] or [tex]\frac{256}{39}[/tex] feet per inch
Step-by-step explanation:
Yeah. This is a question about scaling.
Basically, it's asking how many feet (in real life) are being represented by one inch in the blueprint.
You solve it by dividing the height of the actual house by the height of the blueprint. And, since the actual house is in feet, and the blueprint is in inches, your answer will be in feet per inches.
Does that help?
The unit rate is [tex]6\frac{22}{39}[/tex] feet per inches.
What is division?The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.
Given:
A blueprint for a house shows the height of the house to be 3[tex]\frac{1}{4}[/tex] inches.
The actual house is 21[tex]\frac{1}{3}[/tex] feet tall.
That means,
The unit rate = 64/3 ÷ 13/4
The unit rate = 64/3 x 4/13
The unit rate = [tex]6\frac{22}{39}[/tex].
Therefore, the unit rate = [tex]6\frac{22}{39}[/tex] feet per inches.
