Answer:
8 inches
Step-by-step explanation:
The problem gives us a basic formula, the volume formula for a rectangular prism. All we have to do is use this formula, plug in all the values that are given, and solve for the unknown value.
[tex]V = lwh[/tex]
[tex]192 = l(12)(2)[/tex]
[tex]192 = 24l[/tex]
From here, all we need to do is divide 24 from both sides of the equation, since what you do to one side of the equation you must do to the other!
[tex]8 = l[/tex]
The length of the box will thus be 8 inches.
it is going to be 8 inches Hope it helps !!!!!

(2,-5)
(2,0)
(2,-4)
(0, -3)
Answer:
C (2,-4)
Step-by-step explanation:
You could graph the circle and then graph the points and see...
Or you could them in and see which point makes the left hand less than 4?
So if you wanted to draw it is a circle with center (2,-3) and radius 2.
If you want to do it the other way:
Plug in time!
(2,-5)?
(2-2)^2+(-5+3)^2
0^2+(-2)^2
0+4=4 so not this one
(2,-4)?
(2-2)^2+(-4+3)^2
0+1
1<4 so this one (you can also see this in the drawing:
4. Solve the equation 30a2 – 7 = 29a.
Answer:
Value of a = 7/6 and a = -1/5
Step-by-step explanation:
We need to solve the equation
30a^2 -7 = 29a
Adding -29a on both sides
30a^2-29a-7=0
Solving the quadratic equation using quadratic formula.
[tex]a=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
here a= 30, b =-29 and c=-7
Putting values, and finding the value of a
[tex]a=\frac{-(-29)\pm\sqrt{(-29)^2-4(30)(-7)}}{2(30)}\\a=\frac{29\pm\sqrt{841+840}}{60}\\a=\frac{29\pm\sqrt{1681}}{60}\\a=\frac{29\pm41}{60}\\a=\frac{29+41}{60} \,\, and \,\,a=\frac{29-41}{60}\\a=\frac{70}{60} \,\, and \,\,a=\frac{-12}{60}\\a=\frac{7}{6} \,\, and \,\,a=\frac{-1}{5}[/tex]
So, value of a = 7/6 and a = -1/5

A box contains 8 white cards and 6 black cards.
What is the probability of choosing a black card then a white card, without replacement?
Answer:
The probability of choosing a black card then a white card, without
replacement is 24/91
Step-by-step explanation:
* Lets explain how to solve the problem
- There is a box contain some cards
- There are 8 white cards in the box
- There are 6 black cards in the box
- Two cards are choosing from the box a black card and then a white
card, without replacement
∵ The number of the white cards in the box is 8
∵ The number of the black cards in the box is 6
∴ The total number of the cards in the box = 8 + 6 = 14
- We will chose the first card which is a black card
- We have 6 choices from 14 choices
∵ The number of the black cards is 6
∵ The total number of the cards is 14
∴ P(black) = 6/14 = 3/7
- Now the number of the black cards is 5 and the total number of the
cards is 13 because there is no replacement
- We will chose the second card which is a white card
- We have 8 choices from 13 choices
∵ The number of the white cards is 8
∵ The total number of the cards is 13
∴ P(white) = 8/13
- Lets find the probability of choosing a black card then a white card
∵ P(black) = 3/7 and P(white) = 8/13
∴ P(black and white) = 3/7 × 8/13 = 24/91
* The probability of choosing a black card then a white card, without
replacement is 24/91
A right triangle has an angle that measures 32 degrees. What is the value of the other angle?
Answer:
58
Step-by-step explanation:
right triangle is usually 45°45°90°
given angles: 90°and 32°
90+32=122
then 180-122=58°
Taking the sum of the three interior angles of a triangle and the definition of a right triangle, you get that the value of the other angle is 58°.
The right triangle is a geometric figure that is considered as a polygon formed by three sides that form a right angle and two acute angles. That is, a right triangle is one that has an interior angle that is right, that is, it measures 90º.
On the other hand, the sum of the three interior angles of a triangle is equal to 180 °. Being α, β and γ the interior angles of the triangle, then:
α + β + γ= 180°
Being a right angle, whose value is 90 °, and another angle whose value is 32 °, it is replaced:
90° + 32° + γ= 180°
and solving you get:
122° + γ=180°
γ= 180° - 122°
γ= 58°
Then, the value of the other angle is 58°.

Answer:
7000-24x
Step-by-step explanation:
The question states that the car depreciates every month over the 2 years. This means that the value will go down from its original price. So with that we can rule out the last two choices which has addition.
The depreciation is every month, so in 2 years, there are 24 months. We can get the total deduction by multiplying the depreciation amount and the number of months that had passed over 2 years.
So your answer would be:
7000-24x
Solve this equation for x. Round your answer
to the nearest hundredth.
1 = In(x + 8)
Answer:
e -8 =x
Step-by-step explanation:
1 = In(x + 8)
To get rid of the natural log, raise each side to the base e
e^1 = e^ (ln(x+8))
e^ln cancels
e^1 = x+8
Subtract 8 from each side
e^1 -8 = x+8-8
e -8 =x

what is the point slope form of a line with a slope of 5 and points (-1,3)
Answer:
y - 3 = 5(x + 1)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
here m = 5 and (a, b) = (- 1, 3), hence
y - 3 = 5(x - (- 1)), that is
y - 3 = 5(x + 1) ← in point- slope form

Answer:
Area of circle R = 75π un² or ≈235.5 un²
Step-by-step explanation:
The problem says that m∠TRS = 120º. The total number of degrees in a circle is 360º. 120º is a third of 360º. Therefore, we can prove that the shaded sector is a third of the circle.
The problem then says that the area of the shaded sector is 25π and we have to calculate the area of the entire circle. Since we already know that the shaded sector is a third of the circle, we can simply multiply 25π by 3 in order to calculate the area of t he entire circle.
25π × 3 = 75π.
Area of circle R = 75π un² or ≈235.5 un²
Answer: 75
Step-by-step explanation:
If the measure of TRS is 120, that is 1/3 the total of 360. Meaning the area of the shaded part is 1/3 the area of the full circle. If the area of the shaded part is 25, that means 25 is 1/3 the full area. the equation for that can be (25 = 1/3x) with x being the full area of the circle.
To solve just multiply both sides by the reciprocal of 1/3, which is 3.
25 x 3 = 75, which is your answer.

Solution of the given equation: [tex]x=4 , -7[/tex]
Step-by-step explanation:
An equation is a mathematical statement that states that two things are equal to each other.
A linear equation in one variable is of the form [tex]ax^2+bx+c=0[/tex] where a,b,c are coefficients and x is variable .
Here. given: [tex](x-2)(x+5)=18[/tex]
Using rule (Multiplication is distributive over addition) : [tex]a(b+c)=ab+ac[/tex] ,
we can write this equation as,
[tex](x-2)(x+5) =18\\ x(x+5)-2(x+5) =18\\ x^2+5x-2x-10 =18\\ x^2+3x-10-18 =0\\ x^2+3x-28 =0\\[/tex]
On comparing this equation with [tex]x^2[/tex] - (sum of roots)[tex] x [/tex]+(product of roots) = 0, we get
sum of roots=3 (7-4)
product of roots = -28 [tex]\left ( 7\times -4 \right )[/tex]

What is the value of p? Will give brainliest!
Answer:
35 degrees
Step-by-step explanation:
This is because the angles on the same line are supplementary meaning that they add up to 180 degrees. This means that the two angles which are not x are 180 - 90 = 90 degrees and 180 - 125 = 55 degrees. Since the angles in a triangle are also supplementary as well, then 180 - 90 - 55 = 35 degrees.
Please mark for Brainliest!! :D Thanks!!
For any questions or more information, please comment below and I'll respond as soon as possible.
Answer:
35°
Step-by-step explanation:
Angles on a straight line add up to 180°
The angle opposite 90° will be 90° because
180° - 90° = 90°
The angle opposite 125° will be 55° because
180° - 125° = 55°
So now we know that 2 of the 3 angles sum to 145° ( 55° + 90° ), we have to work out p so
180° - ( 55° + 90° ) = 180° - 145° = 35

What is the sum of -2 and -18
The sum of -2 and -18 is -20.
When you add two negative numbers together, you're essentially combining their magnitudes while keeping the negative sign. In this case, you're adding the magnitudes of 2 and 18, which equals 20, and since both numbers are negative, the sum retains the negative sign. So, -2 plus -18 equals -20.

Which property of exponents must you apply to the expression p^1/2 to derive p as the result?
We apply the following property:
(x^n)^m = x^(n • m)
Let m = 2
(P^1/2)^2 = P^(1/2 • 2) = P
Follow below steps;
The property of exponents that you must apply to the expression p1/2 to derive p as the result is the power law for fractional exponents. This law states that when raising a number to a fractional exponent, it is equivalent to taking its root.
Example: p1/2 is the same as taking the square root of p, resulting in p.
When dealing with fractional exponents like 1/2, remember that they represent roots, such as square roots in this case.
The graph of an equation with a negative discriminant always has which characteristic? no x-intercept no y-intercept no max no mini
Answer:
No x-intercept.
Step-by-step explanation:
The zeroes are not real so it will not pass through the x axis.
Answer:
The correct option is A) No x-intercepts.
Step-by-step explanation:
Consider the provided information.
Nature of solution based on the value of discriminant :
If D = b² − 4ac > 0 then there exist two Real Solutions or roots.
If D = b² − 4ac = 0 then there exist one Real Solutions or roots.
If D = b² − 4ac < 0 then there exist no Real Solutions or roots
Here, we need to remember that the root of an equation and x-intercepts are the same thing.
Now consider the provided information.
The graph of an equation with a negative discriminant means:
D = b² − 4ac < 0
From the above values of discriminant we can say, there exist no Real roots or no x-intercepts.
Thus, the correct option is A) No x-intercepts.
