9) -5k = -10 Help me plz
Answer:
[tex]\boxed {k = 2}[/tex]
Step-by-step explanation:
Solve for the value of [tex]k[/tex]:
[tex]-5k = -10[/tex]
-Divide both sides by [tex]-5[/tex]:
[tex]\frac{-5k}{-5} = \frac{-10}{-5}[/tex]
[tex]\boxed {k = 2}[/tex]
Therefore, the value of [tex]k[/tex] is [tex]2[/tex].

Answers:
a) First statement. Same as 1/2 x 6/11.
b) Second statement. Smaller than 6/11.
c) First statement. Same as 6/11 divided by 2.
================================================
Explanation:
Part (a)
The "of" means "multiply". So we simply replace "of" with the multiplication symbol and that's all we need to do.
---------------
Part (b)
Taking half of something will make it smaller. For example, if you have 100 cookies and you took half of them, then you'll be taking 50 cookies. The value 50 is smaller than 100.
The same idea applies to 1/2 x 6/11.
---------------
Part (c)
Multiplying by 1/2 is the same as dividing by 2.
So [tex]\frac{6}{11} \times \frac{1}{2} = \frac{6}{11} \div 2[/tex]
Note that [tex]\frac{1}{2} \times \frac{6}{11}[/tex] and [tex]\frac{6}{11}\times \frac{1}{2}[/tex] are the same thing because we can multiply two numbers in any order we want.
Answer:
a) First statement. Same as 1/2 x 6/11.
b) Second statement. Smaller than 6/11.
c) First statement. Same as 6/11 divided by 2.

The Confederation Bridge connects News Brunswick to Prince Edward Island. The main part of the bridge rests on piers that form 43 segments. One segment is 8.2 x [tex]10^{2}[/tex] feet. What is the approximate length of the bridge in scientific notation?
Answer: [tex]3.5[/tex] × [tex]10^{4}[/tex]
Step-by-step explanation:
Write an expression to represent the problem.
(8.2 × 10²) × 43
= (8.2 × 10²) x (4.3 x [tex]10^{1}[/tex])
Now, multiply.
(8.2 × 10²) x (4.3 x [tex]10^{1}[/tex])
= (8.2 x 4.3) x ([tex]10^{2}[/tex] x [tex]10^{1}[/tex])
= 35.26 x [tex](10)^{2+1}[/tex]
= 35.26 x 10³
= 3.526 x [tex]10^{4}[/tex]
Mrs. Grape has 90 students. On her last test, 3/10 of these students earned an A. Of those students, 1/9 got a perfect score. How many students got a perfect score?
Answer:
3 students
Step-by-step explanation:
Mrs. Grape has 90 students. On her last test, 3/10 of these students earned an A.
Hence, the number of students that had an A = 3/10 × 90
= 3 × 9 = 27 students
Of those students, 1/9 got a perfect score.
This means of the 27 students, 1/9 had a perfect score.
This means:
1/9 of 27 students = 1/9 × 27
= 3 students
How many students got a perfect score?
Hence, 3 students got a perfect score.

The speed of a rollercoastsr, in miles per hour, is modeled by the funtion g(x) = x⁴ - 4x² + 7x - 8, where x is time measured in seconds. How fast is the roller coaster travelling at 2 seconds?
Answer:
6mphStep-by-step explanation:
Given the expression
g(x) = x⁴ - 4x² + 7x - 8
we are expected to substitute x=2 into the expression and return the result
g(x) = (2)⁴ - 4(2)² + 7(2) - 8
g(x) = 16 - 4x4 + 14 - 8
g(x) = 16 - 16 + 14 - 8
g(x) =14 - 8
g(x) =6
From the substitution the roller coaster is travelling at speed of 6mph

The Homerun Hitter's Academy charges thirty-five dollars per hour for batting lessons, with a registration fee of fifteen dollars per year. Janice's parents paid $155 in the month of August. Part A: Using h to represent hours, write an equation to determine how many hours of batting lessons Janice had in the month of August. Part B: Solve the equation you wrote in Part A for h
Answer:
h = 4 hours
Step-by-step explanation:
Charges per hour = $35
Registration fee = $15
Janice's parents paid $155 in the month of August.
Let
h = number of hours
equation to determine how many hours of batting lessons Janice had in the month of August.
15 + 35h = 155
B. 15 + 35h = 155
35h = 155 - 15
35h = 140
Divide both sides by 35
h = 140 / 35
= 4
h = 4 hours

By putting every value of table x, y = (96 / x) this gives the output of table y so that this is the correct answer.
By definition, it is known that speed equals the ratio of distance and time.
Speed = Distance / Time
Therefore, according to the definition, the last two options are the possible
Let's evaluate the First option:
y = x/96
= 12/96
= 1/8
The table is not fulfilled
Let's evaluate the Second option: (12,8)
y= 2x/3
y= 2*12/3
y = 8
NOW,
(16, 6)
y= 2x/3
2*16/3
the answer will be on a fraction
The table is not fulfilled
Let's evaluate the third option:
y = (3/2) * (1 / x)
x = 12
y = (3/2) * (1/12) = 3/24 = 1/8
The table is not fulfilled
Let's evaluate the fourth option:
y = (96 / x)
x = 12
y = (96/12) = 8
Yes, the table is met.
Option 4 ) y = (96 / x)
By putting every value of table x, y = (96 / x) this gives the output of table y so that this is the correct answer.

Michael makes 16/5 pounds of pumpkin pie filling per minute. How many pounds of pie filling will he make in half an hour?
A.13/10
B.96
C.13/5
D.8/10
Answer:
the answer would be c
Step-by-step explanation:
The amount of pounds of pumpkin made in 30minutes is 96 pounds
Ratio and proportionsFractions are written as a ratio of two integers.
If Michael makes 16/5 pounds of pumpkin pie filling per minute, then;
16/5 pounds of pumpkin = 1 minutes
In order to determine the amount made in half an hour (30 mins)
x = 30mins
Take the ratios
16/5x = 1/30
5x = 480
x = 480/5
x = 96
Hence the amount of pounds of pumpkin made in 30minutes is 96 pounds

An urn contains 5 white and 3 black balls. Two balls are drawn at random without replacement. If X denotes the number of white balls, then find the probability distribution of X.
Answer:
Generally the probability distribution of the number of white balls (X) is
X 0 1 2
P(X) 0.35714 0.5357 0.10714
Step-by-step explanation:
From the question we are told that
The number of white balls is [tex]N_w = 5[/tex]
The number of black balls is [tex]N_b = 3[/tex]
Generally the total number of balls the urn contains is
[tex]N_t = N_w + N_b = 5 + 3 = 8 \ balls[/tex]
Generally the probability that of the two balls drawn that the balls are 2 white balls and 0 black balls is
[tex]P( 2_w \ , 0_b) = \frac{ ^{N_w} C _2 * ^{N_b} C _0 }{^{N_t} C_2}[/tex]
Here C stands for combination hence we would be making use of the combination feature in our calculator
=> [tex]P( 2_w \ , 0_b) = \frac{ ^5 C _2 * ^3 C _0 }{^{8} C_2}[/tex]
=> [tex]P( 2_w \ , 0_b) = 0.10714[/tex]
Generally the probability that of the two balls drawn that the balls are 1 white balls and 1 black balls is
[tex]P( 1_w \ , 1_b) = \frac{ ^{N_w} C _1 * ^{N_b} C _1 }{^{N_t} C_2}[/tex]
=> [tex]P( 1_w \ , 1_b) = \frac{ ^5 C _1 * ^3 C _1 }{^{8} C_2}[/tex]
=> [tex]P( 1_w \ , 1_b) = 0.5357[/tex]
Generally the probability that of the two balls drawn that the balls are 0 white balls and 2 black balls is
[tex]P( 0_w \ , 2_b) = \frac{ ^{N_w} C _0 * ^{N_b} C _2}{^{N_t} C_2}[/tex]
=> [tex]P( 0_w \ , 2_b) = \frac{ ^5 C _0 * ^3 C _2 }{^{8} C_2}[/tex]
=> [tex]P( 0_w \ , 2_b) = 0.35714[/tex]
Generally the probability distribution of the number of white balls (X) is
X 0 1 2
P(X) 0.35714 0.5357 0.10714
