Answer:
since AB and CA is equal, it means that this triangle is an isosceles triangle and that it means that whatever the angle C is, b is also that angle.
so if she is 27 degrees then b is 27° as well
but to find a, you must subtract 180 with the sum of angle b and C
so..
180-(27+27)
180-54
therefore a would be 126°
There are 21 bags of pears on a market stall.
The mean number of pears in each bag is 8. The table shows the number of pears in 20 of the bags.
Calculate the number of pears in the 21st bag.
Numbers of
pears:
Frequency:
6 2
7 6
8 9
9 1
10 2
Answer:
13 pears in the 21st bag
Step-by-step explanation:
mean = total number of pears/total number of bags
8 = x/21
x = 168
number of pears in 20 bags = (6 x 2) + (7 x 6) + (8 x 9) + (9 x 1) + (10 x 2)
= 155
number of pears in the 21st bag = 168 - 155
= 13

Which diagrams show XY tangent to circle C? Check all that apply
Answer:
middle and right pictures are correct answer
Step-by-step explanation:
answer attached
The Figure 2 and 3 shows that XY tangent to circle C.
What is Tangent on circle?Tangent is a line that touches the circle and passes through at a touching point.
Need to prove that xy is a tangent line on the circle.
The circle of radius r and center z.
Sine the tangent of the circle and radius of the circle meet at 90 degrees.
Hence, a right-angle triangle is formed so we can apply the Pythagoras theorem.
Here,
xz = 7 cm
xy = 10 cm
Then
10² = 7² + b²
b² = 100 - 49
b² = 51
Hence, the first one doesn't show the XY tangent to circle C.
Similalry for the rest two figures,
When a segment is tangent to a circle, it is perpendicular to the radius.
Therefore, Figure 2 and 3 shows that XY tangent to circle C.

Taft Middle School is painting a circle on their playground with a radius of 9 feet. What will be the total
area of the circle, in square feet?
Use T = 3.14, and round your answer to the nearest hundredth.
Answer:
Area of a circle = PI * radius^2
Area = 3.14 * 9^2
Area = 3.14 * 81
Area = 254.34 square feet

What is 5,421 rounded to the nearest hundred?
A.4,000
B.5,000
C.5,4000
D.5,200
Answer:
5,000
Step-by-step explanation:
it cant be 400 because the 4 in 5,421 is going to turn into a zero and everything behind that zero is a 0 as well and the thousand place is before the 0 so it stays the same

Can someone help me daughter I just wanna see who helps her
Answer:
Yes.
Step-by-step explanation:
The total amount needed is the amount per teacher x the volume of the water bottles.
16 x 9 = 144
since one gallon is 128 ounces,
144/128 = 1.125 = 1 1/8
Since 1 1/8 is less than 1 1/2, there is enough water.

For the function f(x) = 3x + 2, find x such that f(x) = 14.
Answer:
x = 4
Step-by-step explanation:
To find x, plug in 14 into the function
f(x) = 3x + 2
14 = 3x + 2
Solve for x
14 = 3x + 2
12 = 3x
4 = x
So, the answer is x = 4
The number of microscopic organisms in a petri dish grows exponentially with time. The function P below models the number of organisms after growing t days in the petri dish. Based on the function, which of the following statements is true?
P(t) = 60(3)^t/2
A. the predicted number of organisms in the dish triples every two days
B. The predicted number of organisms in the dish doubles every three days
C. The predicted number of organisms in the dish triples every day
D. The predicted number of organisms in the dish doubles every day
Answer:
A
Step-by-step explanation:
Given
P(t) = 60 [tex](3)^{\frac{t}{2} }[/tex]
Then
P(1) = 60 × [tex]3^{\frac{1}{2} }[/tex] = 60[tex]\sqrt{3}[/tex]
P(2) = 60 × 3 = 180
P(3) = 60 × [tex]3^{\frac{3}{2} }[/tex] = 60 ×[tex]\sqrt{3^{3} }[/tex] = 60 × 3[tex]\sqrt{3}[/tex] = 180[tex]\sqrt{3}[/tex]
P(4) = 60 × 3² = 60 × 9 = 540
P(5) = 60 × [tex]3^{\frac{5}{2} }[/tex] = 60 × [tex]\sqrt{3^{5} }[/tex] = 60 × 9[tex]\sqrt{3}[/tex] = 540[tex]\sqrt{3}[/tex]
P(6) = 60 × 3³ = 60 × 27 = 1620
From these 6 results we see that
P(3) = 3 × P(1)
P(4) = 3 × P(2)
P(5) = 3 × P(3)
P(6) = 3 × P(4)
The predicted number of organisms triples every 2 days → A
Find 8 1/3% of 72.
Answer:
6
Step-by-step explanation:
8⅓% of 72
Change 8⅓% to an improper fraction, to get.
25/3% × 72
= (25/3)÷(100)×72
= (25/3)×(1/100)× 72
= (25/300) × 72
= 1800/300
= 6
The value of [tex]8\frac{1}{3}[/tex]% of 72 is 600.
Given that, [tex]8\frac{1}{3}[/tex]% of 72.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Now, [tex]8\frac{1}{3}[/tex]% of 72
25/3 × 72
= 25 × 24
= 600
Therefore, the value of [tex]8\frac{1}{3}[/tex]% of 72 is 600.
