Answer:
4k - 12
Step-by-step explanation:
k + k + k + k - 12
4k - 12
It's 4k because you're adding and not multiplying

Circumfrance of a circle, (Show working)
Answer:
25.1cm
Step-by-step explanation:
C=2πr
here radius, r=4 cm and π=3.142
Put values in formula.
C=2(3.142)(4)
C=25.1 cm (Rounded to 1 decimal place)
Answer:
25.1 centimeters
Step-by-step explanation:
Formula to find circumference of a circle is C=2πr
Plug in the given values, 3.142 for π, and 4 for r.
C=2 x 3.142 x 4=25.136 centimeters. Round this to 1 decimal place, so our final answer is 25.1

The students at Rudy's school voted between a bear and a lion as the new school mascot. 14 students voted for the bear and 86 students voted for the lion. What percentage of students voted for the bear?
Answer:
14%
Step-by-step explanation:
Given :
Bear voters = 14
Lion voters = 86
Percentage of students who voted bear :
(Bear voters / total number of Voters) * 100%
Total number of voters = (bear voters + lion voters) = (14 + 86) = 100
Percentage of students who voted bear :
(14 / 100) * 100%
0.14 * 100%
= 14%

Nick poured 3/4 fluid ounce of vineger into each ten 1-fluid -ounce test tubes test tubes to use in an experiment for Science Night each circle represent 1 fluid ounce how many fluid ounces did nick pour
Answer:
7.5 fluid ounces
Step-by-step explanation:
Fraction of fluid ounce poured into each test tube
Number of test tubes filled = 10
The number of fluid ounces poured is the product of the amount poured into each test tube and the number of test tubes filled
Therefore, total amount poured :
(3/4 fluid ounces) * 10
0.75 * 10
= 7.5 fluid ounces
Tatum walks her dog 2/3 mile every day after school. How many miles does she walk her dog in 5 days
The number of miles that Tatutm walk her dog in 5 days is given by: Option B: 10/3 (in miles)
How to add two fractions?Let we have to add two fractions as:
[tex]\dfrac{a_1}{b_1} + \dfrac{a_2}{b_2}[/tex]
Then we will find Lowest Common Multiple (LCM) of [tex]b_1[/tex] and [tex]b_2[/tex]. That will help to make the denominators same.
Once the denominators become same, the numerators can add up directly, giving us the final result of addition.
For this case, we're given that:
Each day, Tatum walks her dog 2/3 milesFor 5 days, the total distance her dog walked = 2/3 + 2/3 + 2/3 + 2/3 + 2/3
Since denominators are same, thus:
[tex]\dfrac{2}{3} + \dfrac{2}{3} + \dfrac{2}{3} + \dfrac{2}{3} + \dfrac{2}{3} = \dfrac{2+2+2+2+2}{3} = \dfrac{10}{3}[/tex]
We could've easily done it as: 2/3 + 2/3 + 2/3 + 2/3 + 2/3 = 5 times 2/3 = [tex]5 \times \dfrac{2}{3} = \dfrac{5 \times 2}{3} = \dfrac{10}{3}[/tex]
Thus, the number of miles that Tatutm walk her dog in 5 days is given by: Option B: 10/3 (in miles)

Find m in the diagram please.
Use csc (90) = 10/m.
So, m = 10/csc(90).
m = 8.93997
Answer:
m = 8
Step-by-step explanation:
Here's your solution
=> in traingle DHF and traingle EGF
we have angle DHF and EGF = 90°
and angle F is common , so both traingle are similar by AA similarity
=> 12/m = 15/10
=> m = 120/15
=> m = 8

A corporate team is hosting a fundraising event. It cost them $145 to book the venue, but they are selling the tickets to the event for $15 per person. How many tickets must they sell in order to raise $500?
Answer:
They must sell 43 tickets to raise $500
Step-by-step explanation:
Cost to book the venue = $145
-145 plus 500 (money they need to raise) = $645
Each ticket costs $15

During halftime of a football game, a slingshot launches T-shirts at the crowd. A T-shirt is launched from a height of 4 feet with an initial upward velocity of 80 feet per second. The T-shirt is caught 41 feet above the field. How long will it take the T-shirt to reach its maximum height? What is the maximum height? What is the range of the function that models the height of the T-shirt over time?
9514 1404 393
Answer:
time to max height: 2.5 seconds
max height: 104 ft
range of function: [4, 104]
Step-by-step explanation:
The equation for ballistic motion is ...
h(t) = -16t^2 +v0·t +h0 . . . . where v0 is the initial upward speed and h0 is the initial height
For the given parameters, the height function is ...
h(t) = -16t^2 +80t +4
The time for maximum height is ...
-b/(2a) = -80/(2(-16)) = 2.5 . . . seconds
The maximum height is ...
h(2.5) = (-16·2.5 +80)(2.5) +4 = 104 . . . feet
The range of the function is from the minimum height (at launch) to the maximum height:
4 ft ≤ h(t) ≤ 104 ft.

Please help me ... 6a + 2(c - b) when a = 2, b = 1, and c = 9 I know thë answer but I just need an explanation
Answer:
Step-by-step explanation:
Let the expression representing a situation is,
y = 6a + 2(c - b)
Where, a, b and c are the constants
If a = 2, b = 1 and c = 9
By substituting these values in the expression,
y = 6(2) + 2(9 - 1)
y = 12 + 16
y = 28
Therefore, for all given values of the constants value of y is 28.
Each length of the side of square B is twice the length of the side of square A.
John says that this means the area of square B is twice the area of square A.
Is John right?
Justify your answer.
Answer:
yes
Step-by-step explanation:
because the area of square is l² so John is righrt
Answer:
Area of square= ²
Area of square A= ²
Area of square B = ?
let the length of square A = x
Area of square A =x²
then the length of square B = 2x
Area of square B =2x²
x²means area of square A
so Area of square B =2 times area of squarf A

Which expression is equivalent to the expression below? Select all that apply.
-2/5(15 - 20d + 5c)
1. -30 + 40d - 10c
2. -6 + 8d - 2c
3. -2c + 8d - 6
4. 6 - 3d + 2c
Answer:
2 and 3
Step-by-step explanation:
To simplify this expression, you will need to use the distributive property.
Multiply -2/5 by 15 = - 6, -2/5 by -20d = 8d, and -2/5 by 5c = -2c.
you can switch these around to get -6 + 8d - 2c and -2c + 8d - 6.
