solve for k
11/8=k/4
k= ???
Answer:
5.5
Step-by-step explanation:
11/8 = k/4
If you divide from the denominator you have to divide from the nominator
so 11/2=5.5

Construct a linear equation for the table. What is the slope of the line
We have points (-3, 4), (-1, 2), (4, -3) and (6,-5)
Let's verify it's a line by calculating the slopes between successive points.
Slope is change in y over change in x.
(2 - 4)/(-1 - -3) = -2/2 = -1
(-3 - 2)/(4 - -1) = -5/5 = -1
(-5 - -3)/(6 - 4) = -2/2 =-1
Yup. We have a line of slope -1 through point (-1, 2)
y - 2 = -1(x - -1)
y = -x - 1 + 2
y = -x + 1
That's the linear equation for the table.
Answer: Linear equation: y = -x + 1 slope = -1
Rosa is converting a unit of measure in one system to a unit of measure in another system. 1,760 yd1 mi⋅0.914 m1 yd⋅1 km1,000 m Which statement about Rosa's calculations is true?
Rosa is finding the number of kilometers in a mile.
Rosa is finding the number of meters in a mile.
Rosa is finding the number of miles in a kilometer.
Rosa is finding the number of yards in a kilometer.
Answer: Rosa is finding the number of kilometers in a mile.
Step-by-step explanation:
According to the given information, we have:
1,760 yd=1 mi
0.914 m=1 yd
1 km=1,000 m
So, as we can see, Rosa wants to convert miles to yards, then yards to meters and finally meters to kilometers:
[tex](1 mi\frac{1,760 yd}{1 mi})( \frac{0.914 m}{1 yd})( \frac{1 km}{1,000 m})=1.608 km[/tex]
Then:
[tex]1 mi=1.608 km[/tex] This is the number of kilometers in a mile.

What are the lengths
of the sides in cm?
.
Answer:
90 cm, 180 cm, 240 cm
Step-by-step explanation:
Let the lengths of sides of the triangle be 3x, 6x and 8x
[tex] \therefore \: 3x + 6x + 8x = 5.1 \: m \\ \therefore \: 17x = 510 \: cm \\ \therefore \: x = \frac{510}{17} \\ \therefore \:x = 30 \: cm \\ \implies \\ 3x = 3 \times 30 = 90 \: cm \\ 6x = 6 \times 30 = 180 \: cm \\ 8x = 8 \times 30 = 240 \: cm[/tex]

In a random sample survey of 240 voters, 128 said they would vote for Candidate A in an upcoming election. 1) Based on the random survey, what percent said they will vote for Candidate A? Round to the nearest whole percent. A) 49% B) 53% C) 58% D) 63%
Answer:
B) 53%
Step-by-step explanation:
To find the percent divide the number who will vote for Candidate A over the total number of people surveyed
vote for Candidate A/total surveyed
128/240=0.53333
0.53333*100=53.3333%

parking lot be increased?
Answer:
The length of the parking lot should be increased by 20 feet.
Step-by-step explanation:
First, you find the product of 120 and 80, you get 9600.
Next, add 4400 to it. You get 1400
Finally what would you add to both 120 and 80 to get 14000? 20 to get 140*100.

Step-by-step explanation:
In the recursive formula an = an−1 + 5
[tex]a_n = a_{n-1}+5[/tex]
Suppose if a_5 is the nth term then previous term is a_4
To get the previous term we need to subtract 1 from the n

Crystal owes $8,950 on her Electronics Boutique credit card with a 18.4% interest rate. She owes $6,390 on her Miscellaneous Goods credit cards which has a 22.9% interest rate. What is the total monthly payment needed to pay off both cards in three years, assuming she makes fixed payments and does not charge any more purchases with the card?
Final answer:
The total monthly payment needed to pay off both cards in three years, assuming fixed payments and no further charges, is $550.78.
Explanation:
Calculating the Total Monthly Payment
To calculate the total monthly payment needed to pay off both cards in three years, we need to find the monthly payment for each card and add them together.
Calculating the Monthly Payment for Electronics Boutique Credit Card
Step 1: Calculate the monthly interest rate by dividing the annual interest rate by 12. For the Electronics Boutique card, the monthly interest rate is 18.4% / 12 = 1.53%.
Step 2: Use the formula for calculating the monthly payment on a loan:
Monthly Payment = (Principal * Monthly Interest Rate) / (1 - (1 + Monthly Interest Rate)^(-Number of Payments))
For the Electronics Boutique card, the principal is $8,950 and the number of payments is 3 years * 12 months per year = 36 months.
Plugging the values into the formula, the monthly payment for the Electronics Boutique card is $320.84 (rounded to the nearest cent).
Calculating the Monthly Payment for Miscellaneous Goods Credit Card
Following the same steps as above, the monthly payment for the Miscellaneous Goods credit card is $229.94 (rounded to the nearest cent).
Calculating the Total Monthly Payment
To get the total monthly payment, we add the monthly payments for both cards: $320.84 + $229.94 = $550.78 (rounded to the nearest cent).
Find the area(now I need to make this 20 words longfheieh)
Given:
Image of the figure
To find:
The area of the figure.
Solution:
The image is splitted into two shapes.
One is rectangle and the other is trapezium.
Reference image for answer is attached below.
Rectangle:
Length = 10 cm
Width = 2.8 cm
Area = length × width
= 10 × 2.8
Area = 28 cm²
Trapezium:
Top base = 6 cm
Bottom base = 10 cm
Height = 7.2 - 2.8 = 4.4 cm
Area = [tex]\frac{1}{2} \times(b_1+b_2)\times h[/tex]
[tex]$=\frac{1}{2} \times(6+10)\times 4.4[/tex]
[tex]$=\frac{1}{2} \times16\times 4.4[/tex]
Area = 35.2 cm²
Area of the figure = 28 cm² + 35.2 cm²
= 63.2 cm²
The area of the figure is 63.2 cm².
Solve for X, thats all that I was told
Answer:
x=-1
Step-by-step explanation:
The first step is to expand everything in parentheses.
-2(3x-4)=4(x+3)+6
-6x+8=4x+12+6
Now, combine like terms.
10x=-10
Finally, divide both sides by 10 to isolate x.
x=-1

Solve the following:
a)X + 5 = 11
b) X- 6 = 8
c) 3 + x = 7
d) 12 = x + 5
Answer:
Step-by-step explanation:
a) X + 5 = 11
Subtract 5 from both sides
X = 6
b) X - 6 = 8
Add 6 on both sides
X = 14
c) 3 + X = 7
Subtract 3 on both sides
X = 4
d) 12 = X + 5
Subtract 5 from both sides
7 = X or X = 7
Answer:
a) x=6
subtract 5 from each side.
b) x= 14
add 6 to each side
c) x=4
subtract 3 from both sides
d) x=7
subtract 5 from both sides
Step-by-step explanation:
a) subtract 5 from each side.
b) add 6 to each side
c) subtract 3 from both sides
d) subtract 5 from both sides
f(x)=-x^2+x
f(x)=−x
Find f(−1)
Answer:
Step 1: Set x to -1 in the first equation
[tex]f(x) = -x^2 + x[/tex]
[tex]f(-1) = -(-1)^2 + (-1)[/tex]
[tex]f(-1) = -(1) - 1[/tex]
[tex]f(-1) = -1 - 1[/tex]
[tex]f(-1) = -2[/tex]
Step 2: Set x to -1 in the second equation
[tex]f(x) = -x[/tex]
[tex]f(-1) = -(-1)[/tex]
[tex]f(-1) = 1[/tex]

Is 2(x-y) and 2x-2y equivalent
Answer:
Yes
Step-by-step explanation:
Start with the 2(x-y) and distribute the 2 to each term
2(x)-2(y)
This would equal
2x-2y
Which matches the second equation making the answer yes.
The pairs of expressions that are equivalent are:
- [tex]\( 2(x-y) \)[/tex] and [tex]\( 2x-2y \)[/tex]
- [tex]\( 4(x+y) \)[/tex] and [tex]\( 4y+4x \)[/tex]
- [tex]\( 21q-7p \)[/tex] and [tex]\( (3q-p)(7) \)[/tex]
Let's simplify each expression to see if they are equivalent.
Step 1
1. [tex]\( 2(x-y) \)[/tex] and [tex]\( 2x-2y \)[/tex]:
Simplifying [tex]\( 2(x-y) \)[/tex]:
[tex]\[ 2(x-y) = 2x - 2y \][/tex]
Yes, they are equivalent.
Step 2
2. [tex]\( 4(x+y) \)[/tex] and [tex]\( 4y+4x \)[/tex]:
Simplifying [tex]\( 4(x+y) \):[/tex]
[tex]\[ 4(x+y) = 4x + 4y \][/tex]
Yes, they are equivalent.
Step 3
3. [tex]\( 21q-7p \)[/tex] and [tex]\( (3q-p)(7) \)[/tex]:
Simplifying [tex]\( (3q-p)(7) \)[/tex]:
[tex]\[ (3q-p)(7) = 21q - 7p \][/tex]
Yes, they are equivalent.
Step 4
4. [tex]\( 4(2a-3v) \)[/tex] and [tex]\( 8a+6v \)[/tex]:
Simplifying [tex]\( 4(2a-3v) \)[/tex]:
[tex]\[ 4(2a-3v) = 8a - 12v \][/tex]
No, they are not equivalent.
Step 5
5. [tex]\( 8(3x+c)-1 \)[/tex] and [tex]\( 8c+24x-1 \)[/tex]:
Simplifying [tex]\( 8(3x+c)-1 \)[/tex]:
[tex]\[ 8(3x+c)-1 = 24x + 8c - 1 \][/tex]
No, they are not equivalent.
Step 6
6. [tex]\( 4p+3c \)[/tex] and [tex]\( (c+2p)(2) \)[/tex]:
Simplifying [tex]\( (c+2p)(2) \)[/tex]:
