One angle of a parallelogram measures 45°. What are the measures of the other three angles
in the parallelogram?
Answer: 135, 45, and 135 are the three other angles
==================================================
Explanation:
For a parallelogram, we'll have opposite angles with the same measure. So if one angle is 45 degrees, then the opposite angle is also 45 degrees. The other two angles are 180-45 = 135 degrees each. Adjacent angles in a parallelogram add to 180 degrees.

Which statement is true? Group of answer choices 8.01 is a smaller increase in sales then 8.001. A debt of $17 is a larger value than a debt of $20. LaTeX: \frac{2}{3} 2 3 below zero is a lower temperature than 6 below zero. One half an apple is equivalent to 8 fourths apples.
Answer: The only true statement is:
" A debt of $17 is a larger value than a debt of $20."
Step-by-step explanation:
Let's analyze the options:
A) " 8.01 is a smaller increase in sales then 8.001"
Here you can see the difference:
8.01 - 8.001 = 0.009
The difference is positive, then 8.01 > 8.001.
Then as we are talking of increases in sales, the numbers are positive, then we have that 8.01 is a larger increase in sales than 8.001.
B) "A debt of $17 is a larger value than a debt of $20."
A debt is written as a negative number, then:
A debt of $17 is written as -$17, and a debt of $20 is written as -$20.
Then -$17 is a smaller negative number than -$20
-$17 > -$20
Then this statement is true.
C) " 2/3 bellow zero is lower than 6 bellow zero"
ok, 2/3 bellow zero is: -2/3
6 bellow zero is: -6
-2/3 is larger than -6
-2/3 > -6
then -6 is lower than -2/3, the statement is false.
D) "1/2 of an apple is equivalent to 8/4 apples"
Well, here you can do the quotients:
1/2 = 0.5
8/4 = 2
So these numbers are not equivalents.

Answer:
Step-by-step explanation:
Let's write a equation.
5 ft = 20 seconds
(five feet is reachable in 20 seconds)
Divide both sides by 5.
5/5=1
20/5=4
1 ft = 4 seconds
Let's say the destination is d and f is foot.
d = 4f

A florist is making blue and white flower arrangements. He has 24 blue carnations and 36 red carnations. Each arrangement has the same number of blue carnations and the same number of red carnations. He uses all the flowers to make the greatest number of matching arrangements.
There should be __ total arrangements. ( 2, 4, 6, 12 )
He should include __ blue carnations in each arrangement. ( 2, 4, 6, 12 )
He should include __ red carnations in each arrangement. ( 2, 3, 4, 6 )
Answer:
12 arrangments, 2 blue carnations in each arrangement, 3 red carnations in each arrangment.
Step-by-step explanation:
We can find the gcd of 24 and 36, getting 12.
Therefore, there should be 12 total arrangements.
There are 24 blue carnations:
24 / 12 = 2 blue carnations in each arrangement.
There are 36 red carnations:
36 / 12 = 3 red carnations in each arrangment.

how many times does 1/4 go into 9/16
Answer as a fraction = 9/4
Answer in decimal form = 2.25
================================================
Explanation:
1/4 = 4/16 after multiplying top and bottom by 4
We have some number x such that
(4/16)x = 9/16
we can multiply both sides by 16 to clear out the fractions, getting 4x = 9
Then we divide both sides by 4 to get x = 9/4 = 2.25

the mean of monthly salaries of 15 worker of a company is 2930 .A new worker with monthly salary 3138 join the company.Find the new mean monthly salary of 16 workers
=======================================================
Explanation:
S = sum of the salaries of the first 15 employees
S/15 = mean of the 15 salaries
S/15 = 2930
S = 15*2930
S = 43950
The 15 workers salaries add to 43950.
If we add on a new 16th salary of 3138, then the sum bumps up to
S+3138 = 43950+3138 = 47088
This is the sum of the 16 workers salaries. Divide this over 16 to get the new average
47088/16 = 2943
The new mean is 2943
It is larger than the old mean because the 16th salary is larger than the mean. Effectively this new salary pulls on the mean to make it larger. With very distant outliers, the mean is pulled a lot which often causes problems. So this is why the median is a better measure of center in those situations. Either that measure of center, or using a trimmed mean works as well.
For a sale, a store decreases its prices on all items by 25%. An item that costs $120 before the sale now costs $120 - 0,25($120). Use the distributive property to write an equivalent expression for the items cost now
Answer:
[tex]Cost = \$120 * 1 - \$120 * 0.25[/tex]
Step-by-step explanation:
Given
[tex]Cost = \$120 - 0.25(\$120)[/tex]
Required
Solve using distributive property
[tex]Cost = \$120 - 0.25(\$120)[/tex]
[tex]\$120[/tex] can be rewritten as [tex]1(\$120)[/tex]
So:
[tex]Cost = 1(\$120) - 0.25(\$120)[/tex]
Factorize:
[tex]Cost = \$120(1 - 0.25)[/tex]
Now, we can apply distributive property on the expression;
[tex]Cost = \$120 * 1 - \$120 * 0.25[/tex]
Hence, the above is an equivalent expression.
Solving further, we have
[tex]Cost = \$120 - \$30[/tex]
[tex]Cost = \$90[/tex]

Asif makes a cuboid of plasticine of sides 75cm, 35cm and 21cm. How many such cuboids will he need to form a cube?
Answer:
The number of cuboids that will be needed to form a cube is 2625 cuboids
Step-by-step explanation:
To form a cube, we have;
The length = The height = The depth
The dimensions of the given cuboid = Length = 75 cm, the width = 35 cm, the depth = 21 cm.
Therefore;
The lowest common multiple of 75, 35, and 21, for the cuboid is given as follows;
75 = 5 × 5 × 3
35 = 5 × 7
21 = 3 × 7
Therefore, multiplying 75 by 7, we get;
75 × 7 = 525
Since 7, 5 and 3 are factors of 525, 35 and 21, can also be factors as we check;
525/35 = 15
525/21 = 25
Therefore, the cube will be;
The length of the cube will consist of 7 pieces of the cuboid, arranged with the side 75 cm facing the front
The depth of the cuboid will be 15 cuboids with the side 35 cm facing the sides
The height of the cuboid will be 25 cuboids with the side 21 cm high
The total number of cuboids is therefore;
7 × 15 × 25 = 2625 cuboids
The number of cuboids that will be needed to form a cube = 2625 cuboids.
Which value of x makes x-3/4 + 2/3 = 17/12 true?
Answer:
Step-by-step explanation:
x - 9/12 + 8/12 = 17/12
x - 1/12 = 17/12
x = 18/12= 3/2 = 1 1/2
Value of x = (4 / 3) which makes the given equation true.
What is variable?" Variable is defined as the value which changes as per the condition act on it."
According to the question,
Given equation,
x - (3/4) + (2/3) = (17 / 12)
Convert all fraction into like fractions we get,
x - (3/4) ×(3/3) +(2/3)×(4/4) = (17 /12)
⇒x - (9/12) + (8 /12) = (17 /12)
⇒x - (1/12) = (17 /12)
⇒x = (17/12) +(1/12)
⇒x= (18 /12)
⇒x= (3/2)
Hence, Value of x = (4 / 3) which makes the given equation true.

A room with poor air quality has a particle concentration of 80 units. A fan removes 50% of the remaining particles each hour. What is the particle concentration, in these same units, in the room after 2 hours?
Answer:
20 units
Step-by-step explanation:
Initial particle concentration = 80 units
Particles removed each hour = 50% of the remaining particles
To find:
Particle concentration after 2 hours = ?
Solution:
Particles removed in 1 hour = 50% of remaining particles
i.e. Particles removed in 1 hour = 50% of initial concentration
Particles removed in 1 hour = 50% of 80 = 40
Particles removed in next 1 hour = 50% of remaining particles
i.e. Particles removed in next 1 hour = 50% of concentration after 1 hour
Particles removed in next 1 hour = 50% of 40 = 20
Total particles concentration removed in 2 hours = 40 + 20 = 60 units
Therefore, particle concentration after 2 hours = Initial concentration - Total particle concentration removed in 2 hours
= 80 - 60 = 20 units
