Kathy bought 5 pencils for the price of $6.30. Which equation represents r, the cost, in dollars, of each pencil?
A.r=6.30+5
B.r = 6.30÷5
C.r=6.30×5
D.r=6.30−5
9514 1404 393
Answer:
B. r = 6.30÷5
Step-by-step explanation:
The cost per pencil is found by dividing the cost by the number of pencils.
Here, the cost is $6.30 and the number of pencils is 5. Then the cost per pencil (r) is ...
r = 6.30 ÷ 5

Answer:
c = 9.2m is the answer.
Step-by-step explanation:
a = 6m
b = 7m
c = ?
According to the Pythagoras theorem,
a² + b² = c²
6² + 7² = c²
36 + 49 = c²
c² = 85
c = 9.2m
∴ the distance between the school and the candy store is 9.2m

The area of a triangle is 92 square inches. The base is 23 inches. What is the height in inches? Do not include units in your answer.
Answer:
34,5 ?? I am not good at this but I did 92-23 that's 69 ÷ 2 = 34.5 ?
Answer:
Step-by-step explanation:
We can use the formula for the area of a triangle, to help us find the height:
Area=12⋅b⋅h
Using the formula for area, we can solve for the height by plugging in the information we have about the area and the base:
92=12⋅23⋅h
Isolate h by multiplying both sides by 2 and dividing both sides by 23.
hh=2⋅9223=8
The height is 8 inches.

Solve the given proportion 2/4 = 5/x
The solution to the proportion 2/4 = 5/x is x = 10.
To solve the given proportion 2/4 = 5/x, we can cross-multiply and then solve for x.
Cross-multiplying means multiplying the numerator of the first fraction with the denominator of the second fraction, and then multiplying the denominator of the first fraction with the numerator of the second fraction.
Using the given proportion:
2/4 = 5/x
Cross-multiplying:
2 * x = 4 * 5
Simplifying:
2x = 20
To isolate x, divide both sides of the equation by 2:
(2x)/2 = 20/2
Simplifying:
x = 10
Therefore, the solution to the proportion 2/4 = 5/x is x = 10.

Explain how to find mode, range, and mean
Step-by-step explanation:
The mean is the usual average, so add all of the numbers and then divide.
The mode is the number that is repeated more often than any other.
The range is the largest value and smallest value subtracted.
Answer:
Answer bellow
Step-by-step explanation:
To find mean(average) get all the numbers and and add them together after devide the added number by the number of numbers
To find mode rewrite all the numbers and look for numbers that are repeating (it can be more than one)
To find range take the biggest number from the data set and subtract it from the smallest number in the data set

You randomly choose one of the chips. Without replacing the first chip, you choose a second chip. Find
the probability of choosing the first chip, then the second chip.
White and not a Green
Answer:
probability = 0.07777
Step-by-step explanation:
there are 10 chips
white 1
red 4
green 2
blue 3
the probability of choosing the W chip is 1/10 or 0.10
now there are 9 chips left (the first chip was not replaced)
the probability of choosing a non-green chip is (9-2)/9 = 7/9 = 0.7777
so now I THINK you multiply the two probabilities to get the total probability
probability = 0.1 ·0.7777
probability = 0.07777 which makes sense it has to be less than 0.1

Find the area of the circle. Round your answer to the nearest hundredth. 3 in
Answer:
28.27 or 28 rounded up.
Answer:
7.07 in²
Step-by-step explanation:
Diameter = 3 in ( shown in figure )
Radius = 1/2( diameter) = 1/2 (3) = 1.5 in
Area of a circle = πr²
Area = (3.14)(1.5)²
Area = (3.14)(2.25)
Area = 7.065 in
Area = 7.07 in² ( round off)

Please help!!! Evaluate sin(x)
A. 2.125
B. 0.4706
C.0.8824
D.0.5333
Answer:
sin x = 0.4706
Step-by-step explanation:
Given that,
Height, h = 8
Base, b = 15
Let H be the hypotenuse of the triangle. Using Pythagoras theorem,
[tex]H=\sqrt{8^2+15^2} \\\\H=17[/tex]
We know that,
[tex]\sin\theta=\dfrac{h}{H}[/tex]
So,
[tex]\sinx=\dfrac{8}{17}\\\\\sin x=0.4706[/tex]
So, the correct option is (b).
One angle of a right triangle measures 60°. What is the measure of the other acute angle?
Answer:
30 degrees
Step-by-step explanation:
triangles have 180 degrees
right triangles have a right angle which is 90 degrees
180-90=90
90-60=30
Answer:
30 degrees
Step-by-step explanation:
A triangle has three sides that should add up to 180.
Since it is a right triangle a side has to be 90°.
90°+60°+_30°_ = 180°
