Answer:
The answer is that angle 1 is 70 degrees.
Step-by-step explanation:
Alright so all vertical angles are congruent and the sum of all angles IN and triangle equals 180 degrees. So, the angle on the inside of the top of the triangle is 60 degrees because vertical angles are congruent. Now the angle across from the 130 degree angle is 130 degrees, and we know that the outer and inner angles are supplementary, (add up to 180 degrees) so the angle on the inside is 50 degrees. Then, all angles of a triangle equal 180 degrees therefore, 180-(60+50)= the final angle. Now 70 degrees is the last angle and this angle is vertical to angle 1 which means that angle 1 equals 70 degrees.

Sam drew a rectangle measuring 9 feet in length by 15 feet in width. If she wants to make a similar rectangle measuring 27 feet in length, what should the width be?
Answer:
45
Step-by-step explanation:
If sam made a rectangle 9 feet in length and 15 in width. And we already know the next rectangle is 27 feet we can divide it by 9.
27/9=3
Now that we know its 3x the normal size we can grab the 15 and multiply it by 3.
15x3=45

Amil is given the equation shown.
x2 + 14x + 37 = 0
He completes the square and rewrites the given equation. Which equation is
equivalent to the given equation?
A.
(x + 7)2 – 12 = 0
B.
(x – 7)2 – 12 = 0
C.
(x + 7)2 + 12 = 0
D.
(x – 7)2 + 12 = 0
The equation equivalent to the Amil equation is (x + 7)² - 12 = 0 thus option (A) is correct.
What is the equation?The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
A formula known as an equation uses the same sign to denote the equality of two expressions.
As per the given Amil equation,
x² + 14x + 37 = 0
Add 12 on both sides,
x² + 14x + 37 + 12 = 0 + 12
x² + 14x + 49 = 12
(x + 7)² = 12
(x + 7)² - 12 = 0
Hence "(x + 7)² - 12 = 0 represents the Amil equation's equivalent".

If angle 2 is 45 degrees, what is the measurement of angle 4?
Answer:
angle 4 = angle 2{opposite angles are equal} =45 degrees
Step-by-step explanation:
Answer:
Step-by-step explanation:
Angle 4 is an exterior angle which corresponds to the remote interior angles of 33 degrees and 75 degrees. Through the remote interior angle theorem, we can add the remote interior angles to get the exterior angle So we simply add 33 and 75 to get 33+75 = 108 If you chose not to use this theorem, then you can find angle three by using the fact that all three angles of the triangle must add to 180 degrees. So, 33+75+(angle 3) = 180 108+(angle 3) = 180 108+(angle 3) - 108 = 180 - 108 angle 3 = 72 degrees Then use the fact that angle 3 and angle 4 are supplementary (angle 3) + (angle 4) = 180 72 + (angle 4) = 180 72 + (angle 4) - 72 = 180 - 72 angle 4 = 108 degrees either way, we get the same answ
Store A sells boxes of rice for $2.50 each.
Store B sells rice by the pound for $2.50 per pound.
The cost of an amount of rice at either store can be modeled by the function c(n) = 2.5n, where n is the number of boxes for Store A and n is the number of pounds of rice for Store B.
The domain of c(n) = 2.5n is all the real numbers.
For each store, drag the restriction needed on values of n for c(n) to model each situation.

dexter deposited $6,300 into a savings account that earns 2.60% simple interest per year. how much will he earn in 4 years?
Answer:
= $655.20
Step-by-step explanation:
Simple Interest =( Principal * rate * time)/100
=( $ 6300 * 2.60% * 4years)/100, workout in the brackets first then divide by 100.
= 65520/100
= $655.20
Dexter will earn $655.2.
What is the simple interest?Simple interest is the borrowing amount added only to the principal amount.
Formula to calculate the simple interest is;
S.I. = P x T x R / 100 ,
Where S.I. is simple interest , P is principal amount, T is time period and R is interest rate in a year.
Dexter deposited $6,300 into a savings account that earns 2.60% simple interest per year.
P = $6300
R = 2.60% and T = 4 years
Then by the formula;
6300 x 2.6 x 4 /100
= $655.2
Therefore, Dexter will earn $655.2.
