Answer:
Hey mate here is your answer...
Step-by-step explanation:
smaller circular table to be made
with a diameter only half as big... and diameter of big table is (2*55)= 110cm.... So half diameter of big is (110/2)= 55cm
therefore, diameter of smaller table is 55cm and radius of it's (55/2)= 27.5cm
circumference of circle = 2πr
= 2*3.14*27.5
= 172.7 cm = 27.5cm

What are the solutions of this quadratic equation? x2 − 18x + 58 = 0 A. B. C. D.
Answer:
Step-by-step explanation:
Let's use "completing the square" to solve this quadratic: x^2 − 18x + 58 = 0
We want to rewrite the terms "x^2 - 18x" in the form '(x - h)^2 - h^2 and leave the terms '58 = 0' as they are:
Taking half of the coefficient of x (which coefficient is -18), we get -9. We square this -9, obtaining 81, and then rewrite
"x^2 - 18x" as "x^2 - 18x" + 81 - 81." To this we must append '58 = 0":
x^2 - 18x + 81 - 81 + 58, or x^2 - 18x + 81 - 23 = 0
Now the first three terms condense to the expression
(x - 9)^2, which is then followed by "-23":
(x - 9)^2 = 23
Solve this for x. Taking the square root of both sides, we get
x - 9 = ± √23
so that one root is x = 9 + √23
and the other is x = 9 - √23

Answer:
is that an exponent?
Step-by-step explanation:
can someone please help me?!
Answer:
x = 119
z = 28
Step-by-step explanation:
To find x: Because of same-side exterior angles, you can add x and 61 together to find 180 degrees.
x + 61 = 180
Subtraction: x = 119
To find z: Use given quantities, not found variables for most accurate answer. Because of opposite exterior angles, you can equal them to each other.
61 = 5z - 79
Addition: 140 = 5z
Division: 140/5 = 5z/5
Final Answer = 28 = z

Abishola has an overall GPA of 2.7 over her first three years with 90 credits. She is taking 30 credits her senior and wants her final GPA to be 3.0. Is this possible? If she achieves all A’s her senior year, what will be her final GPA?
(a) 3.025 (b) 3.1 (c) 3.0 (d) 2.94 (e) 2.86 (f) none of the above
Answer:
(a) 3.025
Step-by-step explanation:
The computation is shown below:
In the case when Abishola acheives all As in the senior year, so the final GPA Is
The net GPA is 3
So,
(2.7 × 90 + 30 × x) ÷ 120 = 3
30x = (360 - 2.7 × 90)
x = (360 - 2.7 × 90) ÷ (30)
= 3.9
As she can score till 4 so 3.9 could be possible
In the case when she score 4 on her final year so her GPA is
= (2.7 × 90 + 30 × 4) ÷ 120
= 3.025
PLS HELP!!!!!!!! will mark brainliest!! questions 4, 6, 8. im so lost ahhhh
Answer:
when you ask multiple questions at once, it feels more like i'm doing your HW for you, not that i'm helping you understand , i'll answer these but you really should have been able to do these if you really did all the others. Did you just get tired out? Why can't you do 4, 6, 8? what is it that you don't understand?
Step-by-step explanation:
4) old price = 120 to new price = 240
they ask what is the percent change
How much is the change ( in amount )
the "How much is obvious right? Old price 120 , new price 240.. change is $120
the percent is change / old price = 120 / 120 = 1 and to put it in percent , multiply by 100 , so 100 % change
6) old price = 250 amount of change -100
so what percent of 250 is 100
100 / 250 = 0.4 to get it in percent multiply by 100 = 40%
old price + change = new price
250 + ( -100) = 150 new price is $150
8) 5% mark up , amount of change = $2.50
so 5% of what = 2.50 ?
X* 5% = 2.5
X* 0.05 = 2.5
X=2.5/0.05
X= $50 was the old price
old price + amount change = new price
50 + 2.50 = 52.50
$52.50 is the new price

A circular swimming pool has a diameter of 32 feet. What is the circumference of the pool?
Answer:
~100.48
Step-by-step explanation:
To find the circumference of a pool, you follow the formula of C=πd. This just means that you need to multiply pi (I rounded it to 3.14) by your diameter, which would be 32 in this case. Once you multiply the two together, you should get a circumference that is roughly 100.48. My work is below!
3.14 x 32 = 100.48

ifā=r, then which of the following are true statements?
Check all that apply.
O A. n1/r = a
✓ B. = a
c. a1/nur
O D. a' = n.
Answer:
B. a = rⁿ
C. a¹/ⁿ = r
Step-by-step explanation:
ⁿ√a = r
The above expression can be simplified as follow:
1. ⁿ√a = r
Recall:
ⁿ√a = a¹/ⁿ
Therefore,
a¹/ⁿ = r
2. ⁿ√a = r
Take the n square of both side
(ⁿ√a)ⁿ = rⁿ
(a¹/ⁿ)ⁿ = rⁿ
a = rⁿ
Write an equation of a line with the given slope and y intercept from the graph
Answer:
y = 1.5x - 1 or y = 1 1/2x - 1 or y = 3/2x - 1
Step-by-step explanation:
y = mx + b
b is the point on the y
y = -1
so
b = -1
now the slope
m = rise/run
m = 3/2
so
y = 1.5x - 1

Whats the answer to these? (These are called Proper fractions.)
Jeremiah ran for 3/10 of a mile and then walked another 2/5 of a mile. How far did he travel in all?
Daniel read 4/5 books and Edgar read 1/2 books. How many more books did Daniel read than Edgar?
Jared drove 2/8 miles to the restaurant. He drove another 1/4 miles to the mall. How many miles did he drive in all?
Answer to the first question: 7/10ths of a mile
Explaination: When adding fractions, you need to have a common denominator. Since dividing 3/10 by 2 to get a denominator of 5 makes 3 a decimal, it's easier to multiply 2/5 by 2 to get a denominator of 10. You do the same to the top that you do to the bottom: [tex]\frac{2*2}{5*2} = \frac{4}{10}[/tex]. From there, just add 4/10 and 3/10 to get the answer: 7/10ths of a mile.
Answer to the second question: Daniel read three (3/10) more books
Explaination: Since you can't evenly multiply 5 or 2 to get the opposite number, it's easier to multiply to the lowest common multiple. The easiest way to find that is to multiply both denominators (5*2=10). You'll have to multiply the numerator by the same amount you multipled the denominator by. For Daniel, that would mean: [tex]\frac{4*2}{5*2} = \frac{8}{10}[/tex]. For Edgar, that would mean: [tex]\frac{1*5}{2*5} = \frac{5}{10}[/tex]. So, Daniel read 3 more books than Edgar.
Answer to the third question: 2/4 mile (or 1/2 a mile)
Explaination: 2/8 can be simplified, by dividing the top and bottom by 2, resulting in 1/4. Since both fractions have the same denominator (/4), you can add them to get 2/4ths. This can be simplified further to half (1/2) a mile.
Answer and Step-by-step explanation:
1. Convert [tex]\frac{2}{5}[/tex] to have a denominator of 10.
[tex]\frac{2}{5}[/tex] × [tex]\frac{2}{2}[/tex] = [tex]\frac{4}{10}[/tex]
[tex]\frac{3}{10} + \frac{4}{10} = \frac{7}{10}[/tex]
Jeremiah ran [tex]\frac{7}{10}[/tex] of a mile in total.
2. Convert the denominators of all the fractions to have a 10.
[tex]\frac{1}{2}[/tex] × [tex]\frac{5}{5} =\frac{5}{10}[/tex]
[tex]\frac{4}{5}[/tex] × [tex]\frac{2}{2} = \frac{8}{10}[/tex]
Daniel read [tex]\frac{3}{10}[/tex] more books than Edgar, since 8 books is more than 5 books by 3 books.
3. Convert [tex]\frac{1}{4}[/tex] to have a denominator of 8.
[tex]\frac{1}{4}[/tex] × [tex]\frac{2}{2} = \frac{2}{8}[/tex]
[tex]\frac{2}{8} +\frac{2}{8}= \frac{4}{8}, or\frac{1}{2}[/tex]
Jared drove [tex]\frac{4}{8}[/tex], or [tex]\frac{1}{2}[/tex] miles in total.

Find the solution set of the inequality
5x + 13 > -37.
x ?
Answer:
x > -10
Step-by-step explanation:
5x + 13 > -37
subtract 13 from each side:
5x > -50
x > -10
Answer:
X >/ -10 (imagine this is more or equal to symbol lol)
Step-by-step explanation:
1. subtract 13 from both sides
5x +13-13 >/ -37 -13
2. Simplify
5x >/ -50
3. solve for x (which means divide by 5)
5x/5 >/ -50/5
x>/ -10
