The equation x2 – 1x – 90 = 0 has solutions {a, b}. What is a + b?
Answer:
The value of a+b is 1.
Step-by-step explanation:
The given equation is
[tex]x^2-1x-90=0[/tex]
It is given that this equation has two solutions {a,b}.
First of all find the factors of given equation. The middle term can be written as -10x+9x.
[tex]x^2-10x+9x-90=0[/tex]
[tex](x^2-10x)+(9x-90)=0[/tex]
Taking out common from each parenthesis.
[tex]x(x-10)+9(x-10)=0[/tex]
[tex](x-10)(x+9)=0[/tex]
Using zero product property, we get
[tex]x-10=0\Rightarrow x=10[/tex]
[tex]x+9=0\Rightarrow x=-9[/tex]
The value of a is 10 and b is -9. The sum of both the solutions is
[tex]a+b=10-9=1[/tex]
Therefore the value of a+b is 1.

Bill started west on road U.S. 50, riding a bicycle at an average rate of 9 mph. Four hours later Charles started after Bill on a motor cycle and overtook him in 2 hours. What was Charles' rate?
Which equation could be used to solve for Charles' rate if it is represented by x?
A.2x = 36
B.2x = 54
C.6x = 54
Answer: 2x = 54
I got this question correct on my lesson.
To find Charles' rate, we can set up an equation using the formula Distance = Rate x Time. The correct equation to solve for Charles' rate x is 2x = 36.
Explanation:To solve this problem, we can use the equation Distance = Rate x Time. Let's assume that Charles' rate is represented by x. When Charles overtakes Bill, they have traveled the same distance. Bill has been riding for 4 hours at a rate of 9 mph, so his distance is 9 x 4 = 36 miles. Charles overtakes Bill in 2 hours, so his distance is x x 2. Setting the two distances equal to each other, we have 36 = 2x, which simplifies to 2x = 36. Therefore, the correct equation to solve for Charles' rate x is option A, 2x = 36.

An experiment consists of rolling two fair(not weighted) dice and adding the dots on the two sides facing up. Each die has the number 1 on two opposite faces, the number 2 on two opposite faces, and the number 3 on two opposite faces.
Compute the probability of obtaining the indicated sums in problem.
Final answer:
The student is performing a probability calculation involving rolling two dice and must enumerate all possible outcomes. The probability of a specific sum is determined by dividing the number of ways to achieve that sum by the total number of possible outcomes, 36 in the case of rolling two dice.
Explanation:
The student's experiment consists of rolling two fair dice and adding the numbers that appear on the faces that land upwards. Each die in this scenario has the numbers 1, 2, and 3 on two opposite faces. When calculating the probability of specific sums resulting from this experiment, we need to consider all the possible outcomes (the sample space) and the number of ways to achieve the sum in question.
To find the probability of any particular sum, one must enumerate each distinct way that sum can occur. There are a total of 36 possible outcomes when rolling two dice (6 outcomes per die × 2 dice). For example, to calculate the probability of getting a sum of 4, we need to consider the possible dice combinations (1+3, 2+2, 3+1) that would result in that sum.
As for the probability of an event, it is the number of favorable outcomes over the total number of possible outcomes. If the event is 'rolling a sum of 4', and there are three combinations out of 36 total that yield that sum, the probability would be 3/36 or 1/12. Remember that we must count each die distinctly; although the numbers are the same (1, 2, 3), a roll of 1 on the first die and 3 on the second die is a different outcome from a roll of 3 on the first die and 1 on the second die.

What is the approximate circumference of the circle shown below?
A.102.4 cm
B. 63.4 cm
C. 25.6 cm
D. 51.2 cm
Answer
Formula
[tex]Circumference\ of\ circle = 2\pi r[/tex]
where r is the radius of a circle.
As shown in the image
Diameter of the circle = 16 .3 cm
[tex]Radius\ of\ the\ circle = \frac{16.3}{2}[/tex]
= 8.15 cm
Put in the formula
[tex]Circumference\ of\ circle = 2\pi\times 8.15[/tex]
As
[tex]\pi = 3.14[/tex]
[tex]Circumference\ of\ circle = 2\times 3.14\times 8.15[/tex]
= 51.2 cm (approx)
Therefore the circumference of a circle is 51.2cm (approx) .
Option (D) is correct .
The circumference of the circle [tex]\boxed{51.2{\text{ cm}}}.[/tex] Option (D) is correct.
Further explanation:
The formula for the circumference of the circle can be expressed as follows,
[tex]\boxed{{\text{Circumference of circle}} = 2\pi r}[/tex]
The formula for the area of the circle can be expressed as follows,
[tex]\boxed{{\text{Area of circle}} = \pi {r^2}}[/tex]
Here, “r” represents the radius of the circle.
The relationship between the radius and the diameter can be given by,
[tex]\boxed{r =\dfrac{d}{2}}[/tex]
Here, “d” represents the diameter of the circle.

B.[tex]63.4{\text{ cm}}[/tex]
C.[tex]25.6{\text{ cm}}[/tex]
D.[tex]51.2{\text{ cm}}[/tex]
Explanation:
The diameter of the circle is [tex]16.3{\text{ cm}}.[/tex]
The radius of the circle can be obtained as follows,
[tex]\begin{aligned}{\text{Radius}}&= \frac{{16.3}}{2}\\&= 8.15\\\end{aligned}[/tex]
The radius of the circle is [tex]8.15{\text{ cm}}.[/tex]
The circumference of the circle can be obtained as follows,
[tex]\begin{aligned}{\text{Circumference of circle}}&= 2\times\frac{{22}}{7}\times 8.15\\&=\frac{{44}}{7}\times 8.15\\&= 51.2\\\end{aligned}[/tex]

Ravi is driving 440 miles to visit his grandma. if he drives at an average rate of 55miles per hour, how many hours will it take him to get 3/4 of the way there?
Answer:
Using formula:
[tex]\text{Time} = \frac{\text{Distance}}{\text{Speed}}[/tex]
As per the statement:
Ravi is driving 440 miles to visit his grandma. if he drives at an average rate of 55 miles per hour.
⇒Speed = 55 miles/hour and Distance = 440 miles.
We have to find how many hours will it take him to get 3/4 of the way there.
Distance to get 3/4 of the way there= [tex]\frac{3}{4} \cdot 440 = 3 \cdot 110 = 330[/tex] miles.
Substitute the given values we have;
[tex]\text{Time} = \frac{330}{55}[/tex]
Simplify:
Time = 6 hours.
Therefore, 6 hours will it take him to get 3/4 of the way there

Step-by-step explanation:
If two line intersect each other, then vertical opposite angles are same.
[tex]3x+19=5x-29[/tex] (Vertical opposite angles)
[tex]19+29=5x-3x[/tex]
[tex]48=2x[/tex]
Divide both sides by 2.
[tex]24=x[/tex]
The value of x is 24.
Measure of angle 2 is
[tex]\angle 2 =3x+7=3(24)+7=79[/tex] (Vertical opposite angles)
The measure of angle 2 is 79°.
Measure of angle 1 is
[tex]\angle 1 =180-\angle 2=180-79=101[/tex] (Angle 1 and 2 are supplementary angles)
The measure of angle 1 is 101°.
Measure of angle 3 is
[tex]\angle 3 =180-\angle 2=180-79=101[/tex] (Angle 3 and 2 are supplementary angles)
The measure of angle 3 is 101°.
Measure of angle 4 is
[tex]\angle 4 =4x+5=4(24)+5=101[/tex] (Vertical opposite angles)
The measure of angle 4 is 101°.
Measure of angle 5 is
[tex]\angle 5 =\angle 2=79[/tex] (Alternate Interior Angles)
The measure of angle 5 is 79°.
Measure of angle 6 is
[tex]\angle 5 =\angle 6=79[/tex] (Vertical opposite angles)
The measure of angle 6 is 79°.
Measure of angle 7 is
[tex]\angle 7 =180-(5x-29)=180-(5(24)-29)=89[/tex] (Supplementary angles)
The measure of angle 7 is 89°.
Measure of angle 8 is
[tex]\angle 8 =\angle 7=89[/tex] (Vertical opposite angles)
The measure of angle 8 is 89°.
