Answer:
A = 37 degrees ; B = 82 degrees
Step-by-step explanation:
the angle A plus 143 must measure 180 degrees
angle A = 180 - 143 = 37 degrees
the sum of the inner angles of a triangle is 180 degrees
A + B + C = 180
37 + B + 61 = 180
B = 180 - 98 = 82 degrees

Is Ahmed correct?
Justify your answer by showing your work
Answers
3x + 7x = 10x
2+4= 6
So the answer is 10x + 6 not whatever Ahmed got
Answer:
No. Adding the 2 amounts gives 7x + 6.
Step-by-step explanation:
Adding:

Answers
let me work it out for you
56+47+67+77+55+76+85+80+87+69+47+58
=804
divide that by the total numbers you have in the table that is, 12 numbers
so 804 divided by 12 gives you
=67
let me do the next one
52+32+65+63+52+70+72+61+54+43+29+32
=652
then you take that 652 and divide it by the total numbers given in the table which is also 12
so 652 divided by 12
=that’s 54,3
then you take the final answers
67-54,3
and your final answer is 12,7

Construct an isosceles triangle with the given base and the opposite angle to the base.
Answers
Answer:
Proof of Construction: The compass was used as a measuring tool to obtain (and copy) the length of the given segment. Since the given segment and the copy are the same length, the segments are congruent.
Note: You may also think of the length from A to B as being the radius of a circle with center at A. By copying the circle at A', the radii segments will be congruent.

How much did the two heaviest tomatoes weigh all together?
Answers
Answer:
1 and 6/8
Step-by-step explanation:
1/2 is equivalent to 4/8 when you multiply both the numerator and denominator by 2. So since there are two tomatoes that weigh 1/2 it would be 4/8+4/8= 1. Next you would add 3/8+3/8=6/8. So when you add 1 whole and 6/8 you get 1 and 6/8.
7. An administrator surveys a random sample of 48 out of 900 middle school students. Using the
survey results, the administrator predicts that 225 students are in favor of the new dress code.
How many of the 48 students surveyed were in favor of the new dress code?
Answers
Answer:
12 students
Step-by-step explanation:
225 is 25% of 900 and 25% of 48 is 12.
The number of students is 12 that is surveyed were in favor of the new dress code the answer is 12.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
We have:
An administrator surveys a random sample of 48 out of 900 middle school students.
Using the survey results, the administrator predicts that 225 students are in favor of the new dress code.
The proportion of sample = 225/900
= 0.25
In percent sample:
= 0.25x100 %
= 25%
A number of students surveyed were in favor of the new dress code:
= 25% of 48
= (25x48)/100
= 1200/100
= 12
Thus, the number of students is 12 that is surveyed were in favor of the new dress code the answer is 12.

Can yall tell me what B is? b-7/4=-2/3
Answers
Answer:
1 1/12
Step-by-step explanation:
b-7/4=-2/3
First, in an equation like this, you add 7/4 to each side which will look like this:
b-7/4=-2/3
+7/4=+7/4
We add 7/4 to each side of the equation to balance the numbers.
b=+7/4-2/3 (because the minus symbol is in front, we put that)
Before adding we have to find the least common denominator known as LCD.
We find that by first looking at the denominators or the fractions which are 4,3
4,8,\12/,16,20,24.
3,6,9,\12/,15,18,21,24.
We can also find the LCD by multiplying 3 and 4. As you can see in the list, there are 12's in each list of numbers. We use that to change our fractions.
From the number 4 we find out how many times (x) we have to add 4 to get 12. We do 12/4 which is 3. And 12/3 which is 4.
7 x 3 2 x 4
------- - -------
4 x 3 3 x 4
which equals 21/12-8/12. Now that we have a common denominator, we can subtract.
21 8 13
--- - --- = ----- = 1 [tex]\frac{1}{12}[/tex]
