Answer:
[tex]r=\frac{5}{2}\sqrt{2}[/tex]
Step-by-step explanation:
Triangles And Circles
If a right triangle is inscribed in a circle (or the circle is circumscribed around the right triangle), then the hypotenuse of the triangle is the diameter of the circle.
The right triangle has both legs of known lengths, thus the hypotenuse (the diameter of the circle is):
[tex]d^2=5^2+5^2[/tex]
[tex]d^2=25+25=50[/tex]
[tex]d=\sqrt{50}[/tex]
Since 50=2*25:
[tex]d=5\sqrt{2}[/tex]
Thus the radius of the circle is:
[tex]r=\frac{d}{2}[/tex]
[tex]r=\frac{5\sqrt{2}}{2}[/tex]
[tex]\boxed{r=\frac{5}{2}\sqrt{2}}[/tex]
Two hundred tickets are being sold for a schools draws. What are your chance of winning with one ticket. Express your answer in a percent
Answer:
1%
Step-by-step explanation:
200 out of 1 is 1%
Most likely to win most likely to not win
Answer:
0.5 %
Step-by-step explanation:
1/200 is equivalent to 0.005
0.005 × 100 is 0.5
find the measure of
a. 71 degrees
b. 109 degrees
c. 180 degrees
d. 82 degrees
Answer:
71°
Step-by-step explanation:
Given;
<A=27°
<B=82°
<T=?
We add all angles and subtract it from 180 since an interior angle adds up to 180
<A+<B+<T=180
27°+82°+<T=180
109°+<T=180
<T=180-109
<T=71°
Therefore angle T <T is equal to 71°degrees

Mary and Darryl are selling flower bulbs for a school fundraiser. Customers can buy bags of
windflower bulbs and bags of daffodil bulbs. Mary sold 10 bags of windflower bulbs and 4
bags of daffodil bulbs for a total of $226. Darryl sold 6 bags of windflower bulbs and 4 bags of
daffodil bulbs for a total of $166. What is the cost each of one bag of windflower bulbs and
one bag of daffodil bulbs?
Answer:
15 windflower bulbs
19 daffodil bulbs
Step-by-step explanation:
Given
Represent windflower with W and daffodil with D.
So:
Mary's sales is:
10W + 4D = 226 --- (1)
Darryl's sales is:
6W + 4D = 166 ---- (2)
Required
Solve for W and D
We'll make use of elimination method.
Start by subtracting (2) from (1)
10W - 6W + 4D - 4D = 226 - 166
4W = 60
Multiply both sides by ¼
¼ * 4W = 60 * ¼
W = 60 * ¼
W = 15
Substitute 15 for W in (1)
10W + 4D = 226
10 * 15 + 4D = 226
150 + 4D = 226
Collect like terms
4D = 226 - 150
4D = 76
Multiply both sides by ¼.
¼ * 4D = 76 * ¼.
D = 19

In a town election azeem got 42 percentage of the votes cast and hamza got the remaining votes.If the total number of votes cast is 40000. Find the votes obtained by Hamza .
Answer:
23200
Step-by-step explanation:
42 percent of 40000 is 16800
40000-16800=23200
please give me brainliest!!!<3
Answer:
23,200
Step-by-step explanation:
Total number of votes cast is 40,000
Since Azeem got 42% of the votes casted, then the votes obtained by him would be;
= 42% × 40,000
= 16,800
To get the number of votes obtained by Hamza, we will subtract the votes obtained by azeem from the total votes casted since there are only two candidates in that town, hence number of votes obtained by Hamza would be;
= 40,000 - 16,800
= 23,200.
Therefore, the number of votes obtained by Hamza is 23,200

how to find the circumferenceof a circle
Answer:
You can find the circumference of a circle by using the measurement of its diameter, radius or area. The circumference of a circle is the distance around the circle's edge from one point, meeting back at that point.
Step-by-step explanation:
Answer:
C=2[tex]\pi[/tex]r
Step-by-step explanation:
To find the circumference of a circle you have to use the formula:
c= 2 [tex]\pi[/tex] r
c being circumference
r being radius
If your given diameter than divide that by 2 to get radius
[In case you need it in the future]
To find area of a circle use the formula:
A = [tex]\pi[/tex] r^2
A being area
r being radius

Tobias Gold sells computers at The Office Center.
He is guaranteed a minimum salary of $1,959 per month plus
6.3% commission on total sales. How much in total sales does
he need in order to have a gross pay for the month of $2,784.84?
Answer:
Total sales to be made = $13108.57
Step-by-step explanation:
Given that:
Monthly salary = $1959
Commission = 6.3%
Monthly pay to be earned = $2784.84
Commission amount = 2784.84 - 1959 = $825.84
Let,
x be the amount of sales
6.3% of x = 825.84
[tex]\frac{6.3}{100}x=825.84\\0.063x=825.84[/tex]
Dividing both sides by 0.063
[tex]\frac{0.063x}{0.063}=\frac{825.84}{0.063}\\x=13108.57[/tex]
Hence,
Total sales to be made = $13108.57
solve 3(6b-1)-7(2b+3)=0
Answer:
24/13 or 1.8
Step-by-step explanation:
27b -3 - 14b -21 = 0
13b - 24 = 0
13b = 24
b = 24/13 or 1.8
Answer:
B = 6
Step-by-step explanation
1. (Do the parentheses) 3(6b-1)-7(2b+3) = 18b-3-14b-21
2. (Simplify) 18b-3-14b-21 = 4b-24
3. (Add 24 to both sides) 4b-24+24=0+24
4. (Simplify) 4b = 24
5. (Divide by 4) b = 6
Identify the value of a if
y= ax+ 7x + 2
and the point (2, 12) is on the graph.
Answer:
a=-2
So yep. ;)
Step-by-step explanation:
Alright, so, (2,12), 2 is the x and 12 is the y.
Stick them into the equation: [tex]12=a*2+(7*2)+2[/tex]
Then, solve:
[tex]12=a*2+14+2[/tex]
a = -2
So yes, they're on the graph.
Hope this helped! :)

A florist is looking to make arrangements of red and white roses for bouquets. The flowers are priced so that she makes a profit of $1.25 per red rose and $1.00 per white rose in a bouquet. Her goal is to make at least $1000 from sales of these bouquets. Based on her available time and supplies of red and white roses, she is considering two possibilities: 130 bouquets of 4 red roses and 3 white roses each or 110 bouquets of 3 red roses and 5 white roses each. Will either of these possibilities turn the profit the florist is seeking?
Answer:
Option 1Step-by-step explanation:
Option 1
130 bouquets of 4 red roses and 3 white roses each. Profit is:
130*(4*$1.25 + 3*$1) = $1040 > $1000Option 2
110 bouquets of 3 red roses and 5 white roses each. Profit is:
110*(3*$1.25 + 5*$1) = $962.50 < $1000As we see option 1 is bringing target profit so should be her choice
Answer:
30 bouquets of 4 red roses and 3 white roses each.

Eight more than the product of a number and 3 equals 9.
Answer:
3n + 8 = 9
Step-by-step explanation:
"eight more" represents adding 8, so +8
"product of a number and 3" represents multiplying n by 3, so 3n
"equals 9" means that 3n + 8 = 9
Answer:
n = 1/3
Step-by-step explanation:
n = a number
8 + 3n = 9
3n = 1
n = 1/3

4u+3u+21=70 find the value of the variables
Answer:
u=7
Step-by-step explanation:
First, add 4u and 3u because they are like terms.
7u+21=70
Second, subtract 21 from both sides.
7u=49
Finally, to isolate the variable divide 7 from both sides.
u=7
