Answer:
5x5=25
Step-by-step explanation:
5 x 5
= 5(1 + 0) x 5(1 + 0)
=5(1 + 1 - 1) x 5(1 + 1 - 1)
=5(2 - 1) x 5(2 - 1)
=(10 - 5) x (10 - 5)
=5 x 5 :0
=> 5 x 5 = 5 x 5 = 25
Is the following number irrational?
-8.7
Answer:
No.
Step-by-step explanation:
Rational numbers are any of the following:
Integers (positive whole numbers, negative whole numbers, or zero).Fractions e.g. 3/4Terminating (with an end) or repeating decimals e.g. 0.2 or 0.333333... or 0.343434...Irrational numbers are thus defined as:
Non-terminating (unending), non-repeating decimal numbers. e.g. π, surds ( [tex]\sqrt{2}[/tex] ).This means that -8.7 is not irrational, as it is not an unending, non-repeating number: an easy way to remember how to answer this is to look at whether the number has been expressed in decimal form if it has (unless you have been told that it has been rounded) it must be rational, as it can be written as a decimal number.

One week, Brooklyn earned $179.30 at her job when she worked for 11 hours. If she is paid the same hourly wage, how many hours would she have to work the next week to earn $244.50?
Answer:
Brooklyn would get paid 16.30 hourly. So she will have to work 15 hours the next week to earn 244.50.
Step-by-step explanation:
Divide 179.30 by 11 and you would get 16.30 which is her hourly wage. Then you divide 244.50 by 16.30 to see how many hours she would have to work to earn 244.50.
Answer:
15 Hours
Step-by-step explanation:
179.30 / 11 = $16.3 an hour
244.5 / 16.3 = 15 hours
Find the value of x in each of the following
a) 2x/3= 8
b) 3x/2=6
Answer:
A) X = 12
B) X = 4
Step-by-step explanation:
For both equations, the first step is the same. You must isolate x.
A) 2x/3 = 8
Multiply each side by 3 to get rid of the fraction.
2x = 24
Divide by 2.
x = 12
B) 3x/2 = 6
Multiply each side by 2 to get rid of the fraction.
3x = 12
Divide by 3.
x = 4

/ = division
a/b =
9514 1404 393
Answer:
8
Step-by-step explanation:
The first division was ...
a/-2 = 8
Multiplying by -2, we have ...
a = (-2)(8) = -16
__
The second division was ...
8/b = -4
Multiplying by b/-4, we have ...
8/-4 = b = -2

Then the quotient of interest is ...
a/b = (-16)/(-2)
a/b = 8

Answer:
=-37
Step-by-step explanation:
=-3(3+7) - ( 4+3)
=-3.10-(4+3)
=-3.10-7
=-30-7
=-37
Answer:
Your final answer will be
−37
Step-by-step explanation:
(2−5)(3+7)−(4+3)
= −3(3+7)−(4+3)
= (−3)(10)−(4+3)
= −30−(4+3)
= −30−7
= −37
Triangle A'B'C' is a rotation of triangle ABC by 60 degrees using Q as the center.
Select ALL statements that MUST be true. *
A. Angle ABC is 60 degrees.
B. Angle AQA' is 60 degrees.
C. Points C and C' coincide.
D. Triangles ABC and A'B'C' are congruent.
E. Angle ABC is congruent to angle A'B'C'
F. Segment BC is congruent to segment B'C'
G. Segment BQ is congruent to segment C'Q.
H.Segment AQ is congruent to segment A'Q.
Answer:
The correct options are;
D. Triangles ABC and A'B'C' are congruent
E. Angle ABC is congruent to angle A'B'C'
F. Segment BC is congruent to segment B'C'
H. Segment AQ is congruent to segment A'Q'
Step-by-step explanation:
The given information are;
The angle of rotation of triangle ABC = 60°
Therefore, given that a rotation of a geometric figure about a point on the coordinate plane is a form of rigid transformation, we have;
1) The length of the sides of the figure of the preimage and the image are congruent
Therefore;
BC ≅ B'C'
2) The angles formed by the sides of the preimage are congruent to the angles formed by the corresponding sides of the image
Therefore;
∠ABC ≅ ∠A'B'C'
3) The distances of the points on the figure of the preimage from the coordinates of the point of rotation are equal to the distances of the points on the figure of the image from the coordinates of the point of rotation
Therefore;
Segment AQ ≅ A'Q'.
f (2b) if f (x)= -2x + 4
Answer:
f(2b) = -4b + 4
Step-by-step explanation:
Step 1: Define
f(x) = -2x + 4
f(2b) is x = 2b
Step 2: Substitute and Evaluate
f(2b) = -2(2b) + 4
f(2b) = -4b + 4

1 mile divided by 2 laps =
There are 4 laps in one mile, therefore, "1 mile divided by 2 laps" = 2.
What is division?Division is the process of dividing a number by a given number.
Given, the statement "1 mile divided by 2 laps".
The statement written in mathematical form is:
(1 mile)/2 laps
There are 4 laps in one mile, therefore, substitute 1 mile = 4 laps into the above equation:
(4 laps)/2 laps
= 2
Hence, "1 mile divided by 2 laps" = 2.
