Answer:
$21.25
Step-by-step explanation:
x - x(0.20) = 17
0.8x = 17
x = 21.25
Without graphing, determine how many x-intercepts the function has.
y=3x^2 + 3x +4
y = 2x^2 + 3x + 3 has 0 x intercepts
y = 3x^2 + 3x + 4 has 0 x intercepts

Step-by-step explanation:
How many years is 10000 hours? [365 days = 1.0 year] *
There is 24 hours in a day. Therefore, there are 8760 hours in a 365-day calendar year (365 x 24 = 8760).
How many years is 10000 hours?
Take the total number of hours and divide it by the number of hours in a year.
10000/8760 = 1.1415
Therefore, 10000 hours is approximately 1.14 of a year.

Answer:
First option [tex]0, \frac\pi2, \pi, \frac{3\pi}2[/tex]
Step-by-step explanation:
first of all, let's replace the lhs with the equivalent in sine (from the pythagoran identiy on sine and cosine)
[tex]1-sin^2\theta =1-sin\theta[/tex]
At this point we take 1 from both side, and change signs just out of convenience.
[tex]\sin^2\theta =sin\theta[/tex]
Now we have 2 options. If [tex]sin \theta =0 \leftrightarrow \theta = k\pi[/tex] the equation is verified, and we got two solutions [tex]\theta =0; \theta = \pi[/tex]. Else, we can divide by [tex]sin\theta[/tex] and we get
[tex]sin\theta = 1 \leftrightarrow \theta = \frac\pi2+k\pi[/tex].
We can add everything together and write
[tex]\theta = k\frac\pi2; k\in\{0,1,2,3\}[/tex] or, in our case, the first answer.

Which equation represents the relationship between the angles shown below?
Answer:
4x + 44 = 180
Step-by-step explanation:
4x = 180- 44
4x = 136
x= 136÷ 4
x= 34
Answer:
4x + 44 = 180
Step-by-step explanation:
sum of angles on a straight line = 180
4x + 44 = 180
subtract 44 from both sides
4x + 44 - 44 = 180 - 44
4x = 136
Divide both sides by the coeficient of x
4x = 136

x = 34
if Penelope's car has an average fuel consumption of 3 miles per gallon and she uses 9.5 gallons how far did she drive
Answer:
approximately 3.16 repeated
Step-by-step explanation:
Given parameters:
Average fuel consumption of Penelope's car = 3miles per gallon
Amount of fuel used = 9.5 gallons
Unknown:
Distance of her drive = ?
Solution:
Since her rate of fuel consumption per miles is known, we can simply solve for the distance she covers.
Distance covered = Rate of fuel consumption per miles x amount of fuel used
Distance covered = 3 x 9.5 = 28.5miles
The distance covered by Penelope's car is 28.5miles

One angle in a triangle has a measure that is three times as large as the smallest angle. The measure of the third angle is 45 degrees more than that of the smallest angle. Find the measure of the LARGEST angle.
Answer:
the largest angle are 90 degree
Step-by-step explanation:
let x is the smallest angle
the angles are
x+x+2x=180
4x=180
4x/4=180/4
x=45 degree
2x=90

A triangle has sides with lengths of 60 feet, 63 feet, and 87 feet. Is it a right triangle?
Answer:
Yes
Step-by-step explanation:
We can use the Pythagorean Theorem to check if this triangle is a right triangle:
[tex]a^2+b^2=c^2[/tex]
Note that [tex]a[/tex] and [tex]b[/tex] are the legs of the triangle and [tex]c[/tex] is the hypotenuse:
Substitute the lengths of the sides into the equation:
[tex]60^2+63^2=87^2[/tex]
[tex]3600+3969=7569\\7569=7569[/tex]
Therefore this triangle is a right triangle.

Answer:
2x-10+x+x+10=180, or 4x=180
Step-by-step explanation:
So since the total is 180, you add them all up like an equation.
So,
2x-10+x+x+10
Combine like terms
4x=180
x=45
Then plug it back in to the equations.
x=45
(2x-10)=80
(x+10)=55

according to the department of agriculture consuming 100 grams of banana provides 0.15 milligrams of zinc which of the following is closest to the number of milligrams of zinc provided by 140 grams of banana?
A. 0.15
b. 0.21
C 0.25
D. 0.93
The answer is B how did they get that????
Answer:
x = 0.21
Step-by-step explanation:
[tex]\frac{.15}{100} = \frac{x}{140}[/tex]
.15(140) = 100x
21 = 100x
x = 0.21
The number of milligrams of zinc provided by 140 grams of banana will be 0.21 milligrams. Then the correct option is B.
What are ratio and proportion?A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.
According to the department of agriculture consuming 100 grams of banana provides 0.15 milligrams of zinc.
Then the number of milligrams of zinc provided by 140 grams of banana will be given by the ratio.
Let x be the amount of zinc. Then the equation is given as,
x / 140 = 0.15 / 100
x / 1.4 = 0.15
x = 0.21 milligrams
The number of milligrams of zinc provided by 140 grams of banana will be 0.21 milligrams. Then the correct option is B.
