Answer:
7 hours
Step-by-step explanation:
Step one:
given data
let the total charges be y and the number of hours be x
Company A charges
$60 reservation fee plus another $15 per hour.
so
y=60+15x----------1
Company B charges
$25 reservation fee plus another $20 per hour
y=25+20x------------2
Step two:
equate the 2 expressions above we have
60+15x=25+20x
collect like terms
60-25=20x-15x
35=5x
divide both sides by 5
x= 35/5
x= 7 hours

Answer:
8=73 degrees
5=107 degrees
Step-by-step explanation:
Please mark me brainliest :D
Answer:
Angle 5 is 107 degrees
Angle 8 is 7s degrees
Step-by-step explanation:
First find angle 5. Since the lines are parallel and cut by a transversal, we can say that Angle 3 and Angle 5 are congruent (same measure) since they are alternate interior angles.
Since Angle 3 is 107 degrees, Angle 5 would also be 107 degrees.
Angle 8 is supplementary to Angle 5.
Angle 5 + Angle 8 = 180
Since we know Angle 5 is 107: 107 + Angle 8 = 180
Angle 8 would then be 73 degrees.

How many acute angles does a heptagon have?
Answer:
4 side is the answer I am sure
Answer:
None.
Step-by-step explanation:
I assume we are talking about a regular heptagon.
This has 7 sides and 7 internal angles.
Each internal angle = 180 - (360/7) = 128.6 degrees which is an obtuse angle.

Step-by-step explanation:
simplify the following expression as much as you can use exponential properties. (6^-2)(3^-3)(3*6)^4
Answer:
Simplifying the expression [tex](6^{-2})(3^{-3})(3*6)^4[/tex] we get [tex]\mathbf{108}[/tex]
Step-by-step explanation:
We need to simplify the expression [tex](6^{-2})(3^{-3})(3*6)^4[/tex]
Solving:
[tex](6^{-2})(3^{-3})(3*6)^4[/tex]
Applying exponent rule: [tex]a^{-m}=\frac{1}{a^m}[/tex]
[tex]=\frac{1}{(6^{2})}\frac{1}{(3^{3})}(18)^4\\=\frac{(18)^4}{6^{2}\:.\:3^{3}} \\[/tex]
Factors of [tex]18=2\times 3\times 3=2\times3^2[/tex]
Factors of [tex]6=2\times 3[/tex]
Replacing terms with factors
[tex]=\frac{(2\times3^2)^4}{(2\times 3)^{2}\:.\:3^{3}} \\=\frac{(2)^4\times(3^2)^4}{(2)^2\times (3)^{2}\:.\:3^{3}} \\[/tex]
Using exponent rule: [tex](a^m)^n=a^{m\times n}[/tex]
[tex]=\frac{(2)^4\times(3)^8}{(2)^2\times (3)^{2}\:.\:3^{3}} \\=\frac{2^4\times 3^8}{2^2\times 3^{2}\:.\:3^{3}}[/tex]
Using exponent rule: [tex]a^m.a^n=a^{m+n}[/tex]
[tex]=\frac{2^4\times 3^8}{2^2\times 3^{2+3}}\\=\frac{2^4\times 3^8}{2^2\times 3^{5}}[/tex]
Now using exponent rule: [tex]\frac{a^m}{a^n}=a^{m-n}[/tex]
[tex]=2^{4-2}\times 3^{8-5}\\=2^{2}\times 3^{3}\\=4\times 27\\=108[/tex]
So, simplifying the expression [tex](6^{-2})(3^{-3})(3*6)^4[/tex] we get [tex]\mathbf{108}[/tex]
Determine whether this equation has no solution, one solution, or infinitely many solutions
8p + 1 = 4p +2
Answer:
the equation has one solution, p = 1/4
Step-by-step explanation:
8p + 1 = 4p + 2
subtract 4p from both sides of the equation
8p - 4p + 1 = 4p - 4p + 2
8p - 4p + 1 = 2
4p + 1 = 2
subtract 1 from both sides of the equation
4p + 1 - 1 = 2 - 1
4p = 2 - 1
4p = 1
divide both sides of the equation by 4
4p/4 = 1/4
p = 1/4

in angle HIJ the measure of angle J is equal to 90° HI is equal to 88 ft,and IJ=62ft . find the measure of angle I to the earest tenths of a degree
Answer: [tex]45.21^{\circ }[/tex]
Step-by-step explanation:
Given
[tex]\angle J=90^{\circ }[/tex]
HI=88 ft
IJ=62 ft
From the figure, we can write
[tex]\cos I=\frac{IJ}{HI}=\frac{62}{88}=\frac{31}{44}\\I=\cos^{-1} (\frac{31}{44})=45.207^{\circ }\approx 45.21^{\circ }[/tex]

A line has a slope of 1 and passes through the point (13,1) What is its equation in slope intercept form?
Answer:
y = x - 12
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 1 , then
y = x + c ← is the partial equation
To find c substitute (13, 1) into the partial equation
1 = 13 + c ⇒ c = 1 - 13 = - 12
y = x - 12 ← equation of line

the product of age of a person 10 year ago and 10 year after is 156.find
Answer:
The age of the person now is 16 years old
Step-by-step explanation:
Let us solve the question
Assume that the age of the person now is x years old
∵ The age of the person now is x years old
∵ His age 10 years ago = x - 10
∵ His age 10 years after = x + 10
∵ The product of his ages 10 years ago and 10 years after is 156
→ Multiply his ages before and after and equate the product by 156
∴ (x - 10)(x + 10) = 156
∵ (x - 10)(x + 10) = (x)(x) + (x)(10) + (-10)(x) + (-10)(10)
∴ (x - 10)(x + 10) = x² + 10x - 10x - 100
→ Add the like terms
∴ (x - 10)(x + 10) = x² + (10x - 10x) - 100
∴ (x - 10)(x + 10) = x² - 100
→ Substitute it in the equation above
∵ x² - 100 = 156
→ Add 100 to both sides
∴ x² - 100 + 100 = 156 + 100
∴ x² = 256
→ Take √ for both sides
∴ √x² = √256
∴ x = 16
∵ x represents his age now
∴ The age of the person now is 16 years old

If i roll 2 dice what is the probability that both of them are prime and even?
Answer:
[tex]\frac{1}{36}[/tex]
Step-by-step explanation:
Think of the possibilities of #s each dice can roll: 1 - 6. Only 2 is prime and even meaning that's only one of six possibilities. Since rolling two dice are two subsequent events, multiply the probabilities which should be exactly the same. [tex]\frac{1}{6} *\frac{1}{6}=\frac{1}{36}[/tex]
