Answer:
31.4in
Step-by-step explanation:
A circle's circumference is given by c=2πr.
Using this formula and the given radius (5), we can rewrite the equation to c=2×π×5, and simplify to c=10π.
From there, we want to replace π with 3.14. This gives the equation c=10×3.14.
This can be solved to c=31.4in.
**This content involves the circumference of circles, which you may want to revise. If this is required to be calculated by hand, you may need to revise multiplying with decimals too. I'm always happy to help!
Nick spent 2.5 hours to travel a distance of 90 km by car. What is the rate of the car?
Answer:
36km/h
speed =distance/time
= 90/2.5
=36km/h
CAN ANYONE HELP ME WITH THIS PLEASE??
Answer:
The answer is A. 6.4 and 5.6 and D. 39 and 27.
Step-by-step explanation:
A. 6.4 and 5.6 = 1.6 and 1.4
6.4 / 1.6 = 4
1.4 * 4 = 5.6
So A is correct.
D. 39 and 27 = 13 and 9
39 / 13 = 3
9 * 3 = 27
So D is correct.
Hope this helps! :)
What is the equation of a circle with center (7, 2) and radius 2?
Answer:
(x - 7)² + (y - 2)² = 4
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k ) = (7, 2 ) and r = 2 , then
(x - 7)² + (y - 2)² = 2² , that is
(x - 7)² + (y - 2)² = 4 ← equation of circle

The pair of shoes that Linda wants is on sale today for
40% off. If this means that she will save $54, what is
the original price of the shoes before the discount?
Please help!!
Answer: $135
Step-by-step explanation: x(40/100)=54. x represents the original price and 40/100 is the discount while 54 is the money saved from the discount. This ultimately shows us 40% of something is 54 and that something is represented by x and x equals 135.

Answer:
Y=75x+125
Step-by-step explanation:
Your answer is correct. It is c. The equation is y=Mx+b where m is the slope and b is the y intercrept.
To get M (the slope), get the difference of y-y/x-x. You can use any value of y and x. So, 575-500/6-5=75/1 ot 75. Therefore 75 is m in the equation y=Mx+b.
To get b, you figure out what y is when x is 0. So, looking at the numbers, subtract 75 from 350, which means that y is 275 when x is 2. Subtract 75 again to get 200 (275-75) when x is 1. Subtract 75 one more time to get y when x is 0. 200-75=125. 125 is the y intercept.
Going back to the equation y-Mx+b. Fill in m and b. Y=75x+125.
Consultant plans a survey to determine what % of the patients in a particular hospital were satisfied with the care they received after a major treatment. How many such patients should be surveyed so the margin of error for a 90% confidence interval is within .05? Suppose it is known from a past survey that such a % may be about 80%.
Solution:
Required margin of error = 0.05
Estimated population proportion p = 0.8
Significance level = 0.10
The [tex]\text{provided estimate population proportion}[/tex] p is 0.8
The significance level, α = 0.1 is [tex]z_c=1.645[/tex], which is obtained by looking into a standard normal probability table.
The number of patients surveyed to estimate the population proportion p within the required margin of error :
[tex]$n \geq p(1-p)\left(\frac{z_c}{E}\right)^2$[/tex]
[tex]$=0.8\times (1-0.8)\left(\frac{1.64}{0.05}\right)^2$[/tex]
= 173.15
Therefore, the number of patients surveyed to satisfy the condition is n ≥ 173.15 and it must be an integer number.
Thus we conclude that the number of patients surveyed so the margin of error of 90% confidence interval is within 0.05 are n= 174.

Step-by-step explanation:
This is a parallelogram. In parallelogram, opposite sides are equal.
x + 3 = 6
x = 6 - 3
x = 3
Answer:
3
Step-by-step explanation:
parallelogram - top side = bottom side (parallel sides)
; x + 3 = 6
; x = 6 - 3
; x = 3
(a) The diagram shows four angles around a point
1. Write down an equation in x and y
2. Simplify your equation
3.Find y when x=65°
Answer:
Step-by-step explanation:
The degrees around a point = 360, so
1. x + 95 + 3y + 80 = 360 so
2. x + 3y = 185
3. 65 + 3y = 185 and
3y = 120 so
y = 40
Answer:
y=40
Step-by-step explanation:
sum of all 3 angles : 240
3y+240=360
3y=360-240=120
y=3÷120
y=40

The area of a rectangle is 80 ft2. If the rectangle is 8 feet long, what is its width?
HELPPP PLEASEEE I’ll give brainliest and lots of points
Answer:
Exterior angle is same as the sum of non-adjacent interior angles.#18
m∠3 = 43° + 22° = 65°#20
123° = 90° + m∠4 ⇒m∠4 = 123° - 90° = 33°18) Solution
By using exterior angle is same as the sum of non adjacent interior angles.
→ m<3 = 43° +22°
→ 65°
20) Solution
By using exterior angle is same as the sum of non adjacent interior angles.
→ 123° = 90° + m<4
→ m<4 = 123°-90°
→ 33°

A sandwich shop advertises 108 combinations (one meat + one cheese). There are 3 types of bread and 4 cheeses. How many different meats do they offer? Group of answer choices 9 27 36 None of the above.
Answer:
9
Step-by-step explanation:
A sandwich shop advertises 108 combinations (one meat + one cheese).
There are 3 types of bread and 4 cheeses.
Number of combinations:
3 × 4 = 12 combinations
Therefore, the number of different meats that they do offer is calculated as:
= 108 combinations/ Number of combinations for meat and cheese
108 combinations/12 combinations
= 9 different meats

Answer:
[tex]52[/tex] square units
Step-by-step explanation:
The formula for the area of a rectangle is [tex]A=lw[/tex] where [tex]l[/tex] stands for the length and [tex]w[/tex] stands for the width.
---------->>>>
First, let's find the area of the outside rectangle.
The width of the outside rectangle is 6 units and the length is 11 units.
So,
[tex]A=6(11)[/tex]
[tex]A=66[/tex] square units
This is the area of the yellow rectangle.
---------->>>>
Now, let's find the area of the red rectangle.
The width of the red rectangle is 2 units and the length is 7 units.
So,
[tex]A=2(7)[/tex]
[tex]A=14[/tex] square units
This is the area of the red rectangle.
---------->>>>
Now, to find the answer, we must subtract the area of the outside rectangle by the area of the red rectangle to find the area shaded in yellow.
[tex]66-14=[/tex]
[tex]=52[/tex] square units

Solve for all solutions of p.
We are given the equation below:
[tex] \large{ {p}^{2} = \frac{9}{36} }[/tex]
Use the property below:
[tex] \large \boxed{ {x}^{2} = \frac{a}{b} \longrightarrow x = \pm \frac{ \sqrt{a} }{ \sqrt{b} } \: \: (a \geqslant 0 \: \: and \: \: b > 0)}[/tex]
From the equation:
[tex] \large{p = \pm \frac{ \sqrt{9} }{ \sqrt{36} } } \\ \large{p = \pm \frac{3}{6} \longrightarrow p = \pm \frac{1}{2} }[/tex]
Hence the answer is p = ± 1/2.
Answer
p = 1/2, -1/2p = ± 1/2Both answers work. The second answer is in the plus-minus form.

Question 4
Answer: Choice A) 3/10---------------------
Explanation:
There are 5 green, 9 red, and 6 blue. That makes 5+9+6 = 20 total marbles. Of this total, 6 are blue. The probability of picking blue is 6/20 = 3/10
==============================================================
Question 5
Answer: Choice C) x < 6---------------------
Explanation:
The open hole at 6 means we do not include this value as part of the shaded solution set. So we either have "less than" or "greater than".
We go with "less than" since the shaded region is to the left. This describes all values smaller than 6.
If you had "or equal to" as part of the inequality, then you would have a filled in circle at the endpoint.

Find the range of the function:
f(x) = x + 3, for x ≠ 1
Answer:
All Real Numbers except for 4
Step-by-step explanation:
Objective: Specify domain and range of a function.
The equation is a linear equation. A linear equation range is all real numbers. However x cannot equal 1 so let plug in x to find where the y value CANT be.
[tex]f(1) = 1 + 3 = 4[/tex]
So the range is
All Real Numbers except for 4.
