Makati and his friends rolled two fair number cubes 500 times and recorded the sum of the numbers shown on the cubes each time. On 42 of the trails sum was 10. Which of these is fair number cubes are rolled
Answer:
1/2 anwser is B
Step-by-step explanation:
rolled 2 fair number 500 times right? okay so the sum is a number of anytotal added up correct?
it was shown on the cubes each time ,so you can assume wit 42+10=52?2=x well then just divide that by 500! wich is 1/2

11. If mNJ = "

,
M
o
K
Answer:
∠ MLK = 51°
Step-by-step explanation:
the secant- secant angle MLK is half the difference of the measures of the intercepted arcs , that is
∠ MLK = [tex]\frac{1}{2}[/tex] ( NJ - MK ) ← substitute values
4x + 3 = [tex]\frac{1}{2}[/tex] (170 - (5x + 8) ) ← multiply both sides by 2 to clear the fraction
8x + 6 = 170 - 5x - 8
8x + 6 = 162 - 5x ( add 5x to both sides )
13x + 6 = 162 ( subtract 6 from both sides )
13x = 156 ( divide both sides by 13 )
x = 12
Then
∠ MLK = 4x + 3 = 4(12) + 3 = 48 + 3 = 51°

O B. (f + g)(x) = -4x + 8
OC. (f+ g)(x) = -2x2 + 8x+ 8
OD. (f + g)(x) = -2x2 - 2x + 8
Answer:

⇒ [tex]3x + 5 + ( -2x^{2} - 5x + 3 )[/tex]
⇒ [tex]3x + 5 - 2x^{2} - 5x + 3[/tex]
Combine like terms:
⇒ [tex]-2x^{2} + 3x - 5x + 5 + 3[/tex]
⇒ [tex]-2x^{2} - 2x + 8[/tex]
Answer: D. (f + g)(x) = -2x² - 2x + 8

Evaluate (1/1000)1/3. Express your answer as a fraction in the simplest form.
1/1000 is a fraction and so is 1/3 1/3 is also a power outside of the parenthesis.
Answer:
1/10
Step-by-step explanation:
(1/1000) ^ (1/3) means that you are trying to find ONE of the THREE equal factors of 1 and 1000
1³ = 1
10³ = 10000
so the answer is 1/10
or think of it like ∛ (1/1000) = 1/10
The radius of a circular swimming pool is 7.8 meters. Which is closest to the circumference of this swimming pool?
f 48.98 m g 191.04 m h 24.49 m j 47.76 m
Answer:
F. 48.98 m
Step-by-step explanation:
What is circumference?
The circumference of a circle is the distance around the circle, otherwise known as the perimeter.The formula to find the circumference of a circle is 2πr, or if you're given the diameter, πdHow does it apply here?
We are asked to find the closest circumference given of the swimming pool. We are also given the radius of the pool as 7.8 meters.Solving
Step 1: Plug in your values.
[tex]2 * 3.14 * 7.8[/tex]Step 2: Simplify.
[tex](2*3.14)*7.8 = 6.28 * 7.8[/tex] [tex]6.28 *7.8 = 48.984[/tex] 48.984 ≈ 48.98Therefore, the correct answer is F. 48.98 meters.
What would the monthly payment be for a $5,000 loan with a 6.25% interest rate compounded monthly spread over 60 months? a. $25.31 b. $97.25 c. $217.00 d. $320.95 please select the best answer from the choices provided a b c d
The monthly payment for a $5000 loan at a 5.25% rate is 97.25. Then the correct option is B.
What is a monthly payment?The term loan refers to a sort of credit vehicle in which a sum of money is lent to another party in exchange for the value or principal amount being repaid in the future.
The loan amount is $5000 with a rate of 6.25% over 60 months.
Then the monthly payment (MP) will be
[tex]r = \dfrac{0.0625}{12} = 0.0052[/tex]
Then the formula will be
[tex]\rm MP = P \times \dfrac{r(1+r)^n}{(1+r)^n - 1}\\[/tex]
P = $5000
r = 0.0052
n = 60
Then we have
[tex]\rm MP = P \times \dfrac{0.005208(1+0.005208)^{60}}{(1+0.005208)^{60} - 1}\\\\MP = 97.245 \approx 97.25[/tex]

Which value of x makes the following equation true?
2(x + 10) = x + 23
A.
3
B.
23
C.
13
D.
-7
Answer:
[tex]\Longrightarrow:\boxed{\sf{x=3}}[/tex]
Step-by-step explanation:
Isolate the term of x, from one side of the equation.
2(x+10)=x+23Use the distributive property.
Distributive property:
⇒ A(B+C)=AB+AC
2(x+10)
2*x=2x
2*10=20
2x+20=x+23
First, subtract by 20 from both sides.
2x+20-20=x+23-20
Solve.
Subtract the numbers from left to right.
23-20=3
2x=x+3
Then, you subtract by x from both sides.
2x-x=x+3-x
Solve.
[tex]\Longrightarrow: \boxed{\sf{x=3}}[/tex]
Therefore, the correct answer is x=3.Answer:
x = 3Option A is the correct answer .Step-by-step explanation:
In this question we're given with an equation that is 2(x + 10) = x + 23 and we are asked to find the value of x .
Solution : -
[tex] \longmapsto \: 2(x + 10) = x + 23[/tex]
Step 1 : Solving the parenthesis on left hand side :
[tex]\longmapsto \:2x + 20 = x + 23[/tex]
Step 2 : Subtracting 20 on both sides :
[tex]\longmapsto \:2x + \bold{ \cancel{20}} - \bold{ \cancel{20} }= x + \bold{23 - 20}[/tex]
On further calculations , we get :
[tex]\longmapsto \:2x =x + 3[/tex]
Step 3 : Subtracting x on both sides :
[tex]\longmapsto \:2x - x = \bold{ \cancel{x} }+ 3 - \bold{ \cancel{x}}[/tex]
On further calculations, we get :
[tex]\longmapsto \: \red {\boxed{{x = 3}}}[/tex]
Therefore, value of x is 3 .Now , we're verifying our answer by substituting the value of x in given equation :
2(x + 10) = x + 232 ( 3 + 10 ) = 3 + 232 ( 13 ) = 2626 = 26L.H.S = R.H.SHence, Verified .Therefore, our answer is correct.

Sophie and Marcos are each saving for new bicycles. So far, Sophie has $7 saved and can earn $4 per hour walking dogs. Marcos has $3 saved and can earn $6 per hour at his family's plant nursery. After how many hours of work will Sophie and Marcos have saved the same amount? What will that amount be? Use the system of equations below to complete the graph.
Answer:
2 hours
Step-by-step explanation:
You can express each person's total earning as the formula for a line. (y=mx+b) Use the amount per hour that can be earned as the slope (m) and the amount already earned as the y intercept (b)
Sophie: y=4x+7
Marcos: y=6x+3
Since y is the total amount of money saved and you know that both people need to earn the same amount of money, we know that y is the same in both equations so we can use substitution to substitute one of the equations in for y in the other equation like this:
4x+7=6x+3
From here, solve algebraically
Subtract 3
4x+4=6x
Subtract 5x
4=2x
Divide by 2
x=2
So they will have the same amount of money after 2 hours.
3.4k+(0.63−0.81k)÷0.9=5.7
Part I: Converting the terms into fraction form
Given equation:
3.4k + (0.63 - 0.81k) ÷ 0.9 = 5.7First, let's convert the terms (that are in decimals) into fractions.
3.4k = 34k/100.63 = 63/1000.81k = 81k/1000.9 = 9/105.7 = 57/10Replace the fraction forms in the equation:
3.4k + (0.63 - 0.81k) ÷ 0.9 = 5.734k/10 + (63/100 - 81k/100) ÷ 9/10 = 57/10Part II: Simplifying the division being performed
Since the expression in the parenthesis can't be simplified, we can open the parenthesis. Before we do that, we need to divide the expression by 9/10 (as division is third in BODMAS). This can be done by converting the divisor into it's reciprocal and changing the sign to a multiplication sign.
34k/10 + (63/100 - 81k/100) × 10/9 = 57/10Since there is no other division being performed, we can simplify the distributive property (as multiplication is fourth in BODMAS).
34k/10 + [63/100 × 10/9] - [81k/100 × 10/9] = 57/1034k/10 + [7/10] - [9k/10] = 57/1034k/10 + 7/10 - 9k/10 = 57/10Part III: Isolating "k" to determine it's value
Combine like terms as needed:
34k/10 + 7/10 - 9k/10 = 57/10k(34/10 - 9/10) + 7/10 = 57/1025k/10 + 7/10 = 57/10Subtract 7/10 both sides of the equation to isolate "x" and it's coefficient.
25k/10 + 7/10 - 7/10 = 57/10 - 7/1025k/10 = 50/10Cancel the denominators (as a/b = c/b ⇔ a = c)
25k/10 = 50/1025k = 50Divide both sides by 25 to isolate "k"
25k/25 = 50/25k = 2GIVING BRAINLEST TO THE PERSON THAT CAN EXPLAIN HOW TO DO THIS THE BEST :)

Step-by-step explanation:
A linear function is, well, a line. The line goes on indefinitely without a stopping point.
In one of these functions, there is a line with a stopping point.
The function y = 3/x + 1 has a point that does not have a value, which is 0. 0 cannot be a value in a denominator. All of the other functions can be expressed at all values.
Graphical proof is attached. The function in green has a discontinuity at x = 0 and therefore is not linear.
