Answer:
10
Step-by-step explanation:
do prime factorizations of each number and multiply the common factors
20 = 2 · 2 · 5
30 = 2 · 3 · 5
common factors are 2 and 5
multiply them to get 10
find the measure of angle A
Answer:
35 degrees
Step-by-step explanation:
Sum of angles inside a triangle is 180 degrees.
Right angle is 90 degrees.
180 = 90 + (x + 46) + (x + 66) = 2x + 202
x = -11
A = x + 46 = -11 + 46 = 35
I need help asap!!!!!!!!
Answer:
42
Step-by-step explanation:
in order to find y, we need to find x.
180-65-62=53
x=53
we need to subtract 53-?=11
53-42=11
y=42
Answer:
42
Step-by-step explanation:
because the triangles are congruent, we can place the angle x in CDE to solve for it. Knowing the sum of all angles in a triangle is 180, we can set up the formula below.
62 + 65 + x = 180
Additionally, because the triangles are congruent, we know that the length of CD is equal to GH, letting us set up this formula:
x - y = 11
Solving the first formula, we now know the value of x, 53.
62 + 65 + 52 = 180
Plugging that into the second formula and solving, we get 42.
53 - 42 = 11

figure b is a scaled copy of figure a, what is the scale factor from figure a to figure b?
identify the relationship between angles f, b, and a in the above diagram. PLEASE HELP WILL GIVE BRAINLIEST 7TH GRADE MATH
Answer:
Just remember that straight lines are always 180° (a + b = f)
Step-by-step explanation:
Assuming the triangle is equiangular and equilateral, a b and c are the same, so they are interchangeable.
f + c = 180 becuase it is a straight line. you can switch out c with a because they are the same. So:
f+a=180
(switch out with b)
f+b=180
GUESSING this is equiangular, a and b must add up to 120 because they are are both 60.
If a line is 180 degrees and c is 60 (same as a and b) then f will be 180-60 which is 120. 120 is the same as the sum of a and b, so you could write:
a + b = f
The relationship between angles f, b, and a could be as a + b = f.
What is linear pair?Linear pair of angles are produced when two lines intersect each other at a point. The sum of angles of the linear pair is always 180 degrees.
WE can see that the triangle is equiangular and equilateral, Also angles a b and c are the same, so they are interchangeable.
WE know that the base makes the straight line
f + c = 180
So: f + a = 180
Similarly
f + b = 180
Assuming this is equiangular, a and b must be add to 120, they are both 60 degrees
If we consider the line is 180 degrees and c is 60 then f will be 180-60 which is 120.
120 degree is the same as the sum of a and b, so we could write:
a + b = f
Hence, the relationship between angles f, b, and a could be as a + b = f.

The ratio of number of text messages sent by Lucas to the number of text messages sent by his sister is 4 to 9. Lucas sent 72 text messages. How many text messages did his sister send?
Answer:The number of text messages sent by his sister=162
Step-by-step explanation:
Step 1
The ratio of number of text messages sent by Lucas to the number of text messages sent by his sister =4 to 9= 4:9
Number of text messages sent by Lucas =72
Total ratio is given as 4+ 9= 13
Step 2
such that the total number of messages sent by Lucas and by his sister will be calculated as
Ratio of text messages sent by Lucas/ total ratio x Total messages = Number of text messages sent by Lucas . Let X = Total number of messages
4/13 x X = 72
X=72 x 13 / 4 =234
Therefore, The number of text messages sent by his sister= ratio of text messages sent by his sister/ Total ratio x Total number of messages =
9/13 X 234= 162 messages

9514 1404 393
Answer:
see attached
Step-by-step explanation:
There are several possible ways to describe the "type" of a polynomial. Here, since there is a separate column for "degree", we assume that "type" refers to the number of terms.
Polynomials with 1, 2, or 3 terms are called, respectively, monomial, binomial, and trinomial. The first two expressions listed have 1 term only, so are monomials. The last expression has 3 terms, so is a trinomial.
__
The coefficients are the constant multiplier of the term. Some say a "constant", such as the -8 in the last expression, is not considered a coefficient, because there are no variables that it is multiplying. Here, we have listed it among the coefficients in that expression.
__
The degree of a term is the sum of the degrees of the variables in the term. For terms with only one variable, it is the exponent of that variable. For terms such as the second expression, the degree is the sum of the exponents: 3+4 = 7. The degree of a polynomial with more than one term is the highest degree of all the terms.

slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer: y = -4x
Step-by-step explanation: You would use the formula y = mx + b to solve your problem. When you plug the numbers in, you get y = -4x. There would be no "+ b" because in this case, the y-intercept (b) is equal to zero. Therefore, you would not need to write "y = -4x + 0" because that would not be the equation in its simplest form.
