Answer: 20 laps
Step-by-step explanation:
Given
Roger just ran 5 laps and completes 20% of his goal
Suppose his goal is x laps
So, 20% of x must be equal to 5
[tex]\Rightarrow 20\%\times x=5\\\Rightarrow 0.2x=5\\\\\Rightarrow x=\dfrac{5}{0.2}\\\\\Rightarrow x=\dfrac{50}{2}\\\\\Rightarrow x=25\ \text{laps}[/tex]
So, he needs 20 more laps to complete his goal.

How do you solve this?
=================================================
Explanation:
If we plugged (x,y) = (0,8) into the first inequality, then we get
y < x^2+6
8 < 0^2+6
8 < 0+6
8 < 6
which is false. So we can rule out choice A.
----------------
Trying choice B leads us to
y < x^2+6
2 < 4^2+6
2 < 16+6
2 < 22
That last statement is true, so the first inequality is true for (x,y) = (4,2)
Let's try the other inequality
y > x^2-4
2 > 4^2-4
2 > 16-4
2 > 12
That's false. Since one of the inequalities is false (it doesn't matter which one), this means the entire system is false. We cross choice B off the list.
----------------
Now onto choice C
You should find that y < x^2+6 becomes -4 < 10 after plugging in (x,y) = (-2,-4). Since -4 < 10 is true, we move onto the next inequality.
The inequality y > x^2-4 becomes -4 > 0 after plugging in those mentioned x,y values. The inequality -4 > 0 is false.
We cross choice C off the list.
----------------
The only thing left is choice D. It has to be the answer.
Let's find out if we get true inequalities when plugging in (x,y) = (2,6)
y < x^2+6
6 < 2^2+6
6 < 10 ... true
and
y > x^2-4
6 > 2^2-4
6 > 4-4
6 > 0 .... also true
Both inequalities are true, so the entire system is true. Therefore, (x,y) = (2,6) is one of the infinitely many solutions to this system.
Choice D is confirmed as the answer
----------------
Refer to the diagram below. I've graphed the two dashed boundary curves and the shaded region between. This region is above the y = x^2-4 curve, and below the y = x^2+6 curve. So we're ignoring the stuff above the y = x^2+6 curve.
Points A through D represent the four answer choices in the order given. We see that point D is the only point in the shaded region, so that visually confirms we have the correct answer.
Note: points on the dashed boundaries do not count as solutions.
Two angles of a triangle are 120° and 6° What is the measure of the third angle?
Answer: 54
The angles of a triangle add up to equal 180.
Since we already know two angles, we can just use simple math to find the third.
120 + 6 = 126
180 - 126 = 54
Answer:
54°
Step-by-step explanation:
A triangle ALWAYS measure a 180° Angle in total so if the first and second angle is 120° and 6°, just add it together and will form a 126° Angle so subtract it to 180° Angle and it will result in a 54° Angle

A TV has a listed price of $695.95 before tax. If the sales tax rate is 7.75%, find the total cost of the TV with sales tax included. Round your answer to the nearest cent, if necessary.
Answer:
$749.89
Step-by-step explanation:
TV price = 100% = 695.95
Sales TAX = 7.75% = x
Total price = 107.75% = x dollars
1.0775 * 685.95 = 749.886125 ≈ 749.89

Solve for x.
9 <17 - 4.0
Enter your answer, as an inequality, in the box.
9 <= 17 -4x
Subtract t 17 from both sides:
-8 <= -4x
Divide both sides by-4,
2 <= x
Rewrite the inequality with the x on the left side.
Answer: x <=2

Answer:
Step-by-step explanation:
The lengths of the tangents drawn from an external point tot he circle are equal.
RA = RB = 12.2
QA = QC = 5.9
PC = PQ - QC = 27.4 - 5.9 = 21.5
PC = PB = 21.5
QR = QA + RA = 5.9 + 12.2 = 18.1
PR = PB + RB = 21.5 + 12.2 = 33.7
Perimeter = PQ + QR + PR
= 27.4 + 18.1 + 33.7
= 79.2

Place the following linear equation in slope intercept form: 6x - 4y = 9
Answer:
y = 3/2 x - 9/4
Step-by-step explanation:
bring all the y's to one side.
4y = 6x-9
divide by 4 to isolate the y
y = 6/4x - 9/4
simplify
y = 3/2 x - 9/4
Answer:
y = (3/2)x - 9/4
Step-by-step explanation:
Slope intercept form is
y = mx + b
------------------
6x - 4y = 9
subtract 6x from both sides
-4y = -6x + 9
Divide both sides by -4
y = (3/2)x - 9/4

Two tangents are drawn to a circle from an external point. If the measure of the major arc is 260º, what is the measure, in degrees, of the angle formed by the two tangents?
Answer:
80degrees
Step-by-step explanation:
Using the expression to get the minor arc;
minor arc + major arc = 360degrees
minor arc + 260 = 360
minor arc = 360 - 260
minor arc = 100degrees (central angle)
Note that the central angle and that formed from the intersection of the tangents (X) are supplementary. Hence;
100 + X = 180
X = 180 - 100
X = 80degrees

Jeremy uses 2 feet 3 inches of board for each birdhouse he builds. How many inches of board does he need to make 6 birdhouses? Use a number line to solve?
Answer:
The length of board required is 13 feet 6 inches .
Step-by-step explanation:
Board required to make one bird house = 2 feet 3 inches
= 2 x 12 + 3 = 27 inches
Number of bird houses = 6
So, the board required
= 6 x 27 = 162 inches
13.5 feet = 13 feet 6 inches
