Steven earns extra money babysitting. He charges $31.00 for 4 hours and $46.50 for 6 hours. Enter an equation to represent the relationship. Let x represent the number of hours Steven babysit and y represent the amount he charges. The equation is y answer here
Answer:
y = 7.75x
Step-by-step explanation:
Steven earns extra money babysitting.
Step 1
Let us find the amount he earns per hour based on the charges given in the question.
a) He charges $31.00 for 4 hours
4 hours = $31
1 hour = x
Cross Multiply
4x = $31
x = $31/4
x = $7.75
b) And $46.50 for 6 hours.
6 hours = $46.50
1 hour = x
Cross Multiply
6x = $46.50
x = $46.50/6
x = $7.75
This means, Steven earns $7.75 per hour.
Step 2
Let
x represent the number of hours Steven babysit
y represent the amount he charges.
Therefore, an equation to represent the relationship is written as:
y = $7.75 × x
y = 7.75x

Answer:
V = 696.91
Step-by-step explanation:
Volume of a sphere formula:
V = 4/3πr³
Given:
d = 11
r = d/2
r = 5.5
Work:
V = 4/3πr³
V = 4/3π(5.5)³
V = 4/3π(166.375)
V = 696.91
Taxi A charges $0.25 per mile and an initial fee of $5. Taxi B charges $0.5 per mile and an initial fee of $2. In how many miles will the cost of Taxi B will be the same than Taxi A.
Answer:
12 miles
Step-by-step explanation:
Let
x = number of miles
Taxi A:
5 + 0.25x
Taxi B:
2 + 0.5x
In how many miles will the cost of Taxi B will be the same than Taxi A
Equate cost of taxi A and taxi B
5 + 0.25x = 2 + 0.5x
Collect like terms
5 - 2 = 0.5x - 0.25x
3 = 0.25x
Divide both sides by 0.25
3 / 0.25 = 0.25x / 0.25
x = 3/0.25
x = 12 miles
x = number of miles = 12 miles
what is the value of r if 3r =243?
Answer:
243 divided by 3 equals 81 so r=81
Step-by-step explanation:
Answer:
81
Step-by-step explanation:
Simplify the equation. 3r=243, so divide 3 on both sides, and you get r=81, hence 81 is the answer.

Answer:
11,73 cm (round to the nearest hundredths) ; 112 degrees
Step-by-step explanation:
circumference = 2 x radius x π = 2 x 6 x π = 37,699112 cm
measure of the arc =
37,699112 : 360 = x : 112
x = (112 * 37,699112)/360 = 11,728613 cm
the measure of the angle is given = 112 degrees

Answer:
7/100
Step-by-step explanation:
Find the GCD (or HCF) of numerator and denominator
GCD of 70 and 100 is 10
Divide both the numerator and denominator by the GCD
70 ÷ 10
100 ÷ 10
Reduced fraction:
7
10
Therefore, 70/100 simplified to lowest terms is 7/10.
if x/ 3=3/x then what is the value of x
1.-3
2.3
3.+-3
Answer:
x = ±3 (Option 3)
Step-by-step explanation:
[tex]\frac{x}{3} = \frac{3}{x}[/tex]
Multiply both the sides with 3.[tex]=> \frac{x}{3} \times 3 = \frac{3}{x} \times 3[/tex]
[tex]=> x = \frac{9}{x}[/tex]
Multiply both the sides with 'x'.[tex]=> x \times x = \frac{9}{x} \times x[/tex]
[tex]=> x^2 = 9[/tex]
Root-square both the sides.[tex]=> \sqrt{x^2} = \sqrt{9}[/tex]
[tex]=> x = (+3) \: or \: (-3)[/tex]
∴ x = ±3
Find tan S and tan R. Write each answer as a fraction in simplest form
We know the trigonometric ratios that tan = opposite/adjacent So, tan S is equal to 15/8 and tan R is equal to 8/15.
What are the trigonometric ratios?Trigonometric ratios for a right-angled triangle are from the perspective of a particular non-right angle.
In a right-angled triangle, two such angles are there which are not right-angled(not of 90 degrees).
The slanted side is called the hypotenuse.
From the considered angle, the side opposite to it is called perpendicular, and the remaining side will be called the base.
We know that tan = opposite/adjacent
tan S
opposite: 45
adjacent: 24
So,
tan S = 45/24 = 15/8
tan R
opposite: 24
adjacent: 45
So,
tan R = 24/45 = 8/15

Answer: Choice A) Solar energy; renewable
The image shows panels that convert solar energy to electricity. This is an example of using renewable sources.
This is in contrast to something like coal energy which is nonrenewable. Coal is finite and will run out some day, unlike the sun's energy which won't run out any time soon. Sure it will eventually die off in about 5 billion years or so, but that timescale is much longer compared to the amount of coal is left. So this is a benefit to using renewable resources.

someonee helpp plss
Answer:
to find the WX you have to use this formula
m>S=TR-WX/2
45=116-WX/2
90=116-WX
WX=116-90
WX=26
the answer is D 26
Answer:
D
Step-by-step explanation:
The secant- secant angle WSX is half the difference of the intercepted arcs, that is
[tex]\frac{1}{2}[/tex] (116 - WX)° = 45° ( multiply both sides by 2 to clear the fraction )
116 - WX = 90° ( subtract 116° from both sides )
- WX = - 26° ( multiply both sides by - 1 )
WX = 26° → D

Give the slope of the line which is perpendicular to
y = −3x −2
Answer:
1/3
Step-by-step explanation:
y = −3x −2
This is in the form y = mx+b where m is the slope
This line has a slope of -3
We want the slope of a line that is perpendicular
Lines that are perpendicular have slopes that are negative reciprocals
m = -(1/-3)
m = + 1/3
The slope of a line that is perpendicular is 1/3

Answer:
4w = 25
w= 6.25
Step-by-step explanation:
We know that w + w + w + w is the same as 25 because the scale is balanced.
This is writted as 4w = 25
To solve for w, divide both sides by 4:
(4w)/4 = 25/4
w = 25/4
w = 6.25

Answer:
13 miles
Step-by-step explanation:
The shortest distance would be a straight line between the two points. This would be a hypotenuse of a right triangle
We can use the Pythagorean theorem to determine the length
a^2+b^2=c^2
5^2 +12^2 = c^2
25+144= c^2
169 = c^2
Taking the square root of each side
sqrt(169) = sqrt(c^2)
13 = c
