Answer:
The answer is D
Step-by-step explanation:
The absolute value number is its relationship to other numbers without regards for its sign. So say the question is asked: whats the absolute value of -1. The absolute value would be positive four because 1 is one place away from 0 on the number line.
5. Ms. Peregrino is using her cards to call on
students in period 7. She has 34 students.
She has 2 girls with the same name. What is the probability of Ms.peregrino calling in those girls with the same name one after the other?
Answer: 2/34
Step-by-step explanation: there are 2 sticks with the same name and the total number of students are 34 so its 2/34
What is the surface area of the triangular prism represented by the net below?
Answer:
608 cm^2
Step-by-step explanation:
Top and bottom rectangles:
2(10*16)
= 2(160)
= 320
Middle rectangle:
(12*16)
= 192
Two triangles:
2((12*8)/2)
= 2(96/2)
= 96
Surface area of the whole prism:
320 + 192 +96
= 608
The surface area of the triangular prism is 608 cm² represented by the net.
What is the volume of a rectangular prism?The volume of the rectangular prism is the product of the base area and the height.
The triangular prism is given in the question, as shown:
As per the given figure, the surface area of the triangular prism will be:
Three rectangles ( top, bottom, and middle) + Two triangles
2(10×16) + (12×16) + 2((12×8)/2)
2(160) + 192 + 2(96/2)
320 + 192 + 96
Apply addition operation, and we get
608
Thus, the surface area of the triangular prism is 608 cm².

1/2
1/5
1??
Answer:
1
Step-by-step explanation:
Total number of portions = 10
unshaded portion= 5
number of even numbers =
probability of unshaded portion = 5/10 = 1/2
probability of even number = 5/10 = 1/2
Probability of landing on unshaded or even portion= probability of landing on unshaded portion + probability of landing on even number = 1/2 + 1/2 = 1

M(9,8) is the midpoint of RS. The coordinates of S are (10, 10). What are the coordinates of R?
(8,6)
(11, 12)
(9.5,9)
(18, 16)
Answer:
(8,6)
Step-by-step explanation:
8 and 10 are 2 units apart. So 8 and the x value of R have to be two units apart. That would be 6. Use the same process for the y value.
David correctly factored the expression m^2 -12m - 64.
Which expression did he write?
(1) (m - 8)(m - 8) (3) (m - 16)(m + 4)
(2) (m - 8)(m + 8) (4) (m +16)(m - 4)
Explain why
Answer:
(3) (m - 16)(m + 4)
Step-by-step explanation:
Given the expression:
m^2 -12m - 64.
Using quadratic formula:
[tex] m = \frac{-b \pm \sqrt{b^2 - 4(a)(c)}}{2(a)} [/tex]
[tex] m = \frac{12 \pm \sqrt{(-12)^2 - 4(1)(-64)}}{2(1)} [/tex]
[tex] m = \frac{12 \pm 20}{2}[/tex]
[tex] m_1 = \frac{12 + 20}{2}[/tex]
[tex] m_1 = 16[/tex]
[tex] m_2 = \frac{12 - 20}{2}[/tex]
[tex] m_2 = -4[/tex]
Then, the factored expression is:
(m - 16)(m + 4)

Answer:
Step-by-step explanation:
1X+17=121X+17=12
1X=12−171X=12−17
1X=72×7−27×21X=72×7−27×2

1. A ball is thrown off of a balcony and it's height can be
modeled using the function, f(x) = -x2 + 4x + 12, where x is
the number of second after the ball was released. After
how many seconds will it the ball to hit the ground?
Answer:
After 6 seconds, the ball will hit the ground.
Step-by-step explanation:
f(x)=-x^2 + 4x + 12
Since we want to see when it touches the ground, the height must be equal to 0, so f(x) has to equal 0.
0=-x^2 + 4x + 12
If you factor this equation, you'd get:
(-x + 6)(x + 2) = 0
We get the 2 and the 6 from the factors of 12. The two factors of 12 have to be able to add or subtract into 4, and in this case, 6-2 is 4. (If you multiply this equation out, you'd get the same one you started with)
Since we need it to equal 0, the way to multiple to 0 is to have a zero itself. This means that either (-x+6) is equal to 0 or (x+2) is equal to 0. The only x values that satisfy this is 6 and -2. You can't have -2 seconds after, so it has to be 6.
Hope that helps.
PLZ I need help with the first problem!
Answer:
5/32
Step-by-step explanation:
You would change 1/2 to 2/4 so you can subract 1/2 from 3/4 .You do 3/4-2/4 and you get 1/4.Then you would multiply the height and width so you multiply 1/4 and 1 1/4 and 1/2.

Find "C" when "F" = 120.
Round to tenths.
C= 5F-160 /9
Answer:
C = 48.9
Step-by-step explanation:
C= 5F-160 /9
C= (5F -160)/ 9
Put F =120
C = (5(120) - 160)/9
C= (600 - 160)/9
C = 440/9
C = 48.89≈ 48.9

Which number is greatest?
6.23 x 10^12
O 6.23 x 10^8
6.23 x 10^-6
6.23 x 10^3
Answer:
The first one is greatest.
Step-by-step explanation:
If the sum of 4040 consecutive integer numbers is 2020, find out the absolute difference between the first number and the last number.
Let [tex]x[/tex] be the smallest of the consecutive integers summing to 2020. Then the largest integer in the sum is [tex]x+4039,[/tex] so our answer is [tex]\boxed{4039}.[/tex]
For completeness, though, let's solve for the value of [tex]x[/tex] that satisfies the conditions of the problem. Recall that the sum of an arithmetic series with first term [tex]a_1,[/tex] last term [tex]a_n,[/tex] and [tex]n[/tex] terms, is [tex]\frac{n(a_1+a_n)}{2}.[/tex] Plugging in our known values gives us the equation [tex]\frac{4040(2x+4039)}{2}=2020,[/tex] which simplifies to [tex]2x+4039=1.[/tex] Thus, [tex]x=-2019,[/tex] so the 4040 consecutive integers are [tex]-2019,-2018,\dots,-1,0,1,\dots,2018,2019,2020.[/tex] Notice how everything except the [tex]2020[/tex] cancels out!
Solve dy/dx = (1-x)(1-y)
Answer:
[tex]y=1-e^{c_{2}}}*e^{-x} *e^{x^2}[/tex]
Step-by-step explanation:
We begin with the differential equation [tex]\frac{dy}{dx} =(1-x)(1-y)[/tex]
Firstly, we need to get the [tex]y[/tex] and [tex]dy[/tex] as well as the [tex]x[/tex] and [tex]dx[/tex] on the same sides as each other
To do this, we can multiply each side by [tex]dx[/tex] and divide each side by [tex](1-y)[/tex]
Doing this will give us the following differential
[tex]\frac{1}{1-y} dy=(1-x)dx[/tex]
Now, we can integrate each side
[tex]\int\limits\frac{1}{1-y} \, dy =\int (1-x) \, dx\\\\-ln(1-y)=x-x^2+c_{1}[/tex]
Now, we need to solve for y
[tex]-ln(1-y)=x-x^2+c_{1}\\\\ln(1-y)=x^2-x+c_{2} \\\\1-y=e^{x^2-x+c_{2}} \\\\y=1-e^{x^2-x+c_{2}}\\\\y=1-e^{c_{2}}}*e^{-x} *e^{x^2}[/tex]
