Answer:
A = π(r)²
Step-by-step explanation:
The area of a circle is the inside of a circle. It can be found by multiplying pi by the radius raised to the power of 2 (squaring the radius).
Which expressions are equivalent to 35+30s-45t?
Answer:
B and C
Step-by-step explanation:
5 * (7 + 6s - 9t) = 7*5 + 6s *5 - 9t*5
= 35 + 30s - 45t
(-35 - 30s + 45t)*(-1) = (-35)*(-1) - 30s *(-1) + 45t*(-1)
= 35 + 30s - 45t
we said that the ratio of girls to boys in the class was 2:9. if there were 90 boys in the 9th grade, how many girls are there
Answer:
20
Step-by-step explanation:
If the ratio of boys is 9 there are 90 boys. If 9=90 then 1= 10. 10 x 2 = 20
I hope this helps :0)
20 girls
Step-by-step explanation:
For every 9 boys there are 2 girls, so, if we have 90 boys, 9x10=90 and then since we have the 10 we use it to do 2x10 to get 20 girls

Please Help!!! Identify two equations from above that represent parallel lines and explain why you choose them
Identify two equations from above that represent perpendicular lines and explain why you choose them
Answer:
parallel : (b) and (g)
perpendicular : (d) and (f)
Step-by-step explanation:
straight line equation : y = mx + c
Lines that are parallel have the the same gradient(m),
(b) and (g) are parallel, both of them has m= 1/2
Lines that are perpendicular will have the product of their
gradient(m) equal to -1. So, m1 × m2 = -1
(d) and (f) are perpendicular, because : -4 × ¼ = -1
Hope I was able to help:))

Answer:
C: 24 = [tex]w^{2}[/tex] + 3 (the yellow option)
Step-by-step explanation:
We can see that 24 obviously represents our total area, we are told that the rug is 3 feet LONGER THAN it is wide, suggesting that addition will be involved.
In conclusion the most logical answer would be C: 24 = [tex]w^{2}[/tex] + 3
what is the slope of the equation?
y = -1/3x + 3
Answer:
-1/3
Step-by-step explanation:
y=mx+b
m=-1/3
Answer:
[tex] - \frac{1}{3}[/tex]
Step-by-step explanation:
y=mx+b
m stands for slope and -1/3 holds that postion

Not a polynomial
Step-by-step explanation:
A polynomial is a combination of terms separated by
+

signs. A polynomial does not contain variables raised to negative or fractional exponents, variables in the denominator or under a radical, or any special features such as trigonometric functions, or logarithms.
The tire has a diameter of 33 inches. If the tire rotates one time, about how many inches will the tire travel?
Given:
Diameter of a tire = 33 inches.
To find:
The distance covered by the tire if it rotates one time.
Solution:
We have,
Diameter of a tire = 33 inches.
Radius is the half of diameter. So, the radius of the tire is
[tex]\dfrac{33}{2}=16.5[/tex]
Thus, r = 16.6 inches.
We have to find the distance covered by the tire if it rotates one time. It means, we need to find the circumference of the tire.
[tex]C=2\pi r[/tex]
[tex]C=2(3.14)(16.5)[/tex]
[tex]C=103.62[/tex]
Therefore, the distance covered by the tire if it rotates one time is 103.62 inches.
In the diagram below shows the cross section of a bridge with a semi circle hole. If the perimeter of the cross section is 24m. Calculate
B. Area of the cross section ( π =22/7)
Answer:
the area is 85.239 m²
Step-by-step explanation:
perimeter of a semi circle = ½πd
24 = ½ x 22/7 × d
24 x 7/11 = d
15.27 m = diameter...
area = ½πr²
= ½ × 22/7 x 7.365 x 7.365
= 85.239 m2

Find the measure of DC if m
Answer:
B. 132°Step-by-step explanation:
Find the measure of arc BD
m∠A = 1/2(arc BC - arc BD) 2*36° = 150° - arc BD arc BD = 150° - 72° = 78°Find the measure of arc DC
arc BD + arc BC + arc DC = 360°arc DC = 360° - (150° + 78°) = 360° - 228° = 132°Correct choice is B

What is the slope of the line that passes through the points (-4,-1) and (-2,-5)?
Step-by-step explanation:
m= (-5+1)/(-2+4)
m= -4/2
m= -2
enter the equation of the line in the form =mx where m is the slope .
Answer:
y = 3x
Step-by-step explanation:
The line goes up 3 and goes across by 1. Using the rise over run structure, it will be 3/1 or 3. m is equal to the slope, making it y = 3x, since y doesn't intercept anything, you don't need to put + anything at the end. Hope I helped. :D

x+3<5
please i need the answer quick!!
x<5-3
x<2
so your answer is
[tex] - \infty < x < 2[/tex]
Question:
x + 3 < 5, Find x.
Answer
⟹ x + 3 < 5
( Subtracting 3 from both the sides of the inequality )
⟹ ( x + 3) - 3 < 5 - 3
⟹ x < 5 - 3
⟹ x < 2
It means that any number that is smaller than 2 will satisfy the inequality.
FOUNTAINS The circular fountain in
front of the courthouse has a radius of
9.4 feet. What is the circumference of
the fountain? Round to the nearest
tenth.
Answer:
The fountain has a circumference of 9 feet.
Step-by-step explanation:
5 and above get rounded to the next tenth and 4 and below rounds to the nearest 10 also and that would be 9 if it was 9.5 or above the answer would have been 10.0
