Answer:
divide by 8
2.25 cubic units
Step-by-step explanation:
3 x 6 half cubes = 18 half cubes
one cubic unit =1/8 cubic units
18/8=2.25 cubic units
Answer:
12.
Step-by-step explanation:
18 ÷ 1 1/2 = 12.
There are 18 half cubes total. It is 18 divided by 1 and a 1/2 equals 12 which is eighteen divided by one and a half equals twelve.
18 divided by 1 1/2 = 12.

Answer:
[tex]\huge\boxed{\sf x =28 \textdegree}[/tex]
Step-by-step explanation:
Given that,
∠IAK = 62°
∠IAK + ∠IAD = 90° (Complementary angles)
62 + ∠IAD = 90°
Subtract 62 to both sides
∠IAD = 90 - 62
∠IAD = 28°∠IAD = ∠ACB (Corresponding angles are equal)
So,
∠ACB = 28°∠ACB = ∠GCJ (Vertically opposite angles are equal)
So,
28° = x°
OR
x° = 28°[tex]\rule[225]{225}{2}[/tex]
Answer:
28 degrees
Step-by-step explanation:
If two lines cross each other, it makes 4 angles, and 2 angles from opposite sides have the same length. Since line KL and line IJ crossed, angle KAI and angle LAJ will have the same angle.
--> Angle LAJ is 62 degrees
If we look closely, there is a triangle ABC, and since the question said that line KL and line FG is perpendicular, the angle ALG will be 90 degrees.
We know that in a triangle, there are three angles, and the angle measures combined equals 180.
Since we know two angles: 90 and 62, we take them away from 180 to find the last angle BCA.
--> 180 - 90 - 62 = 28
--> Angle BCA = 28 degrees
Like I said at the beginning, if two lines cross each other, opposite angles are the same size. So angle x will also be equal to angle BCA, which is 28 degrees.
Angle x = 28 degrees

Answer:
Triangles are congruent due to SAS
Angles are congruent due to CPCTC
Step-by-step explanation:
In order to prove the congruency of the angles, we have to prove the congruency of the triangles.
ME=MR is given so that is a side
They share angle M so that is an angle
And, MA=MN which is given so that is a side.
The two triangles are congruent due to SAS postulate
So the angles are equal due to CPCTC
Angles E and R are congruent as they are the corresponding parts of two congruent triangle.
Given is a figure which shows two connected triangles ΔEMA and ΔRMN,
We need to prove ∠E ≅ ∠R.
Considering the triangles,
ME = MR [given]
MA = MN [given]
∠M is common angle in both triangles,
So, ΔEMA ≅ ΔRMN by SAS postulate.
So, ∠E ≅ ∠R by CPCTC.
Hence proved.

Answers
To figure out the average of Michael and Melissa we must add up all their test scores and divide the by 7; which is the number of tests they took.
Michael:

how much will you have to pay back in total if you borrowed $400 from the bank for a year at 12%
Answers
400x.12= 48
2) add interest and loan amount
400+48= 448
You would have to pay back $448 in total after one year.
What is the amount on the loan?The simple interest formula can be expressed as;
I = P × r × t
Where I is interest, P is principal, r is interest rate and t is time.
Given the parameters:
Principal P = $400 (the initial loan amount)
Rate r = 12% = 12/100 = 0.12
Time t = 1 year
Interest = ?
To determine the interest, we can use the above formula for simple interest:
I = P × r × t
Interest = $400 × 0.12 × 1
Interest = $48
Money to be paid back will be:
Amount = Principal + Interest
Amount = $400 + $48
Amount = $448
Therefore, the accrued amount to be paid is $448.

A would be incorrect because the problem is asking what the area of the stamp would be. In order to find area, we multiply length and width by each other. The given equation we initially had shows division, and would therefore be incorrect. B would be incorrect because although the equation has the correct evaluation symbol, the formula for identifying length would be L = A / W, which means length equals area divided by width. Because the area is 1/4 in this problem, the expression used for evaluation would be 1/4 divided by 1/5. D is incorrect because, like B, the evaluation expression would be 1/4 divided by 1/5.
Your final answer: Because C is the only problem that gives us a corresponding expression to the initial expression, C is the correct answer. If you need extra help, let me know and I will gladly assist you.
Answer:
Step-by-step explanation:
(A)length of a stamp=1/5foot
wide of a stamp=1/4foot
area of the stamp=?
area of the stamp=length of a stamp *wide of a stamp

width of the room=1/5meter
length of the room=?

1/4 = length of the room/5
5/4 =length of the room
length of the room =5/4=1 1/4(C)the area of the canvas=1/5square yard
width of the canvas=1/4 yard

[tex]-x + 9[/tex]
Step-by-step explanation:
Hello!
We want to combine any like terms and distribute the signs properly to the terms in the parentheses.
First, remove the parentheses by distributing the signs:
[tex]-(2x - 1) + 3(x + 4) - 2(x + 2)[/tex][tex]-(2x) - (-1) + 3(x) + 3(4) - 2(x) - 2(2)[/tex]Remember that negative times negative is positive
[tex]-2x + 1 + 3x + 12 - 2x - 4[/tex][tex]-2x + 3x - 2x + 1 + 12 - 4[/tex][tex]-x + 9[/tex]
The simplified form is [tex]-x + 9[/tex].
Another way to think about the negative sign is by replacing it with -1, so essentially you are multiplying the whole parentheses by -1.

What is the total amount due after 6 months on an initial loan of $1,400 at 12.5% annual interest.
Answers
Answer: $1487.50
Step-by-step explanation:
hey there again!
Facts:
Principal (starting amount): $1,400
Annual interest rate: 12.5% of the principal. Whenever you get an annual interest rate as a percentage, its always that percentage of the starting amount.
Time given: 6 months, 1/2 a year
the question asks "total amount due' in 6 months. Basically, we want to know how much they will have in their account after 6 months.
Step 1: Find how much interest he will get in 6 months as a percentage.
6 months is 1/2 of a year, so find 1/2 of 12.5
1/2 of 12.5
1/2 x 12.5
0.5 x 12.5
6.25%
Step 2: Find how much interest he gets, but as a number.
Principal: $1400
6.25% of 1400= $87.50
Step 3: Find the total amount of money he will have after 6 months.
he starts with 1400, and gets an additional $87.50 added to his account after 6 months. How much does he have now?
To answer this, add to find the total:
87.50+1400= $1487.50
