Answer:
3+2w=l
2(l+w)=7 1/3
2(3+2w+w)= 7 1/3
6+6w= 7 1/3
-6 both sides
6w=1 1/3
/6 both sides
w=2/9
2/9*2=4/9+3=3 4/9
4/9*3 4/9= 1 43/81

Work out the percentage change to 2 decimal places when a price of £198 is increased to £209.99.
Answer:
The percentage change = 6.05%
Step-by-step explanation:
New value = £209.99
Old value = £198
Percentage change = [New Value - Old Value] / [Old Value] × 100
= [209.99 - 198] / [198] × 100
= [11.99] / [ 198] × 100
= 0.06 × 100
= 6.05%
Therefore, the percentage change = 6.05%

Answer:
the length of the minute hand is 36/100 . 150 = 54 (mm)
y is the distance between the minute hand and the hour hand now
x is the angle beween the minute hand and the hour hand, so we have:
cos x = 36/54 = 2/3 => sin x = [tex]\sqrt{1-(\frac{2}{3})^{2} }=\frac{\sqrt{5} }{3}=\frac{y}{54}[/tex] => y = 18√5 (mm)
a) see in the ques, u can see that in 45', the minute hand will move a distance equal to 2 times its length and a distance = 2.18√5 (mm)
=> the distance which the minute hand will move is 54.2 + 2.18√5 = 188,50 (mm)
b) the distance which the minute hand will move in 1h is 54.4 - 18√5 = 175,75(mm)
the distance which the hour hand will move in 1h is 36.4 = 144 (mm)
=> the minute hand will move: 175,75 - 144 = 31,75(mm) further than the hour hand

and explain how you would find the measurement of
they cylinder's volume in cubic centimeters. Be specific,
include any formulas you will need, identify the
components of the cylinder, explain whether you need
to round, and do not forget to include units of
measurements.
Academic Vocabulary:

Answer:
16,713.4 cc
Step-by-step explanation:
You are given the height (6) and circumference (187) and the formula for the volume of the volume of a cylinder is [tex]\pi *r^{2} *h[/tex]. You first need to find the radius of the cylinder using the equation [tex]C=2\pi r[/tex]. Doing so, you get 29.76 cm for the radius. After this, you plug in 29.76 and 6 into the equation to get 16,713.4 cc.

If
s= t+7s/5 and s= -2 what is the value of t?
A) -24
B) -4
C) 4
D) 24
Answer:
C
Step-by-step explanation:
Given
s = [tex]\frac{t+7s}{5}[/tex] ← substitute s = - 2 into the equation
- 2 = [tex]\frac{t+7(-2)}{5}[/tex] ( multiply both sides by 5 to clear the fraction
- 10 = t - 14 ( add 14 to both sides )
4 = t → C

plz help, The graph of y = f(x) is shown below. What are all of the real solutions of f(x) = 0?
Answer:
The real solutions of f(x)=0 are: 0, 2, 5, 6
Step-by-step explanation:
We are given:
The graph of y = f(x)
We need to find all of the real solutions of f(x) = 0?
By looking at the graph we need to find the values of y when x =0
Looking at the graph, when x=0 we get
0, 2,5 and 6
So, the real solutions of f(x)=0 are: 0, 2, 5, 6

Answers:
x = 5
y = -5
==================================================
Work Shown:
3x + 2y - 5 = 0
3(y+10) + 2y - 5 = 0 ... replace x with y+10
3y+30+2y-5 = 0 .... distribute
5y+25 = 0
5y = -25 .... subtract 25 from both sides
y = -25/5 .... divide both sides by 5
y = -5
Use this y value to find x
x = y+10
x = -5+10
x = 5
------------------
As a way to check, plug these x and y values into the first equation
3x + 2y - 5 = 0
3(5) + 2(-5) - 5 = 0
15 - 10 - 5 = 0
5 - 5 = 0
0 = 0
This confirms the first equation and helps confirm our answers.
Solve by using substitution. Express your answer as an ordered pair.
{2x + y = 1
{y = x -5
Answer:
All the best this is the answer
2x+y=1
y=x-5
substitute: y=x-5 in 2x+y=1
2x+x-5=1
2×+x=1+5
2x+x=6
3x=6
x=6/3
x=2
finding y:
substitute x=2 in 2x+y=1
2×2+y=1
4+y=1
y=1-4
y=-3

. Taylor made gallons of fruit punch. What is the total number of 8-fluid-ounce cups of punch that Taylor made?
This question is incomplete
Complete Question
Taylor made 2 1/2 gallons of fruit punch. What is the total number of 8-fluid-ounce cups of punch that Taylor made?
Answer:
40
Step-by-step explanation:
Step 1
Let's convert the gallons to fluid ounces
1 gallon = 128 fluid ounces
2 1/2 gallons = x
Cross Multiply
x = 2 1/2 gallons × 128 fluid ounces
x = 320 fluid ounces
2 1/2 gallons of fruit punch = 320 fluid ounces of fruit punch.
Step 2
The total number of 8-fluid-ounce cups of punch that Taylor made is calculated as:
8 fluid ounce = 1 cups
320 fluid ounces = x
Cross Multiply
8x = 320
x = 320/8
x = 40
Hence, the total number of 8-fluid-ounce cups of punch that Taylor made is 40
Under his cell phone plan, Elijah pays a flat cost of $64.50 per month and $5 per gigabyte. He wants to keep his bill at $87.50 per month
Next door to me lives a man with his son. They both work in the same factory. I watch them going to work through my window. The father leaves for work ten minutes earlier than his son.one day I asked him about it and he told me that it takes 30 minutes for him to walk to his factory, whereas his son is able to cover the distance in only 20 minutes. If the father were to leave the house 5 minutes earlier then his son, then the son would catch up with his father in 2k minutes. where k is-----
9514 1404 393
Answer:
k = 5
Step-by-step explanation:
Suppose the distance to the factory is 1 unit. Then the speed the father walks is ...
speed = distance/time = 1 / 30 . . . . units per minute
When the father leaves 10 minutes earlier than the son, his position t minutes after the son starts walking is ...
d = 1/30(t +10)
Similarly, when the father starts 5 minutes earlier than the son, his position t minutes after the son starts walking is ...
d = (1/30)(t +5)
We want that to be the same as the distance the son covers t minutes after he starts walking. The son's progress is ...
d = 1/20t
To find the value of k such that the distance covered is the same 2k minutes after the son starts, we will use t=2k and d=d, so ...
(1/30)(2k +5) = (1/20)(2k)
4k +10 = 6k . . . . . multiply by 60
10 = 2k . . . . . . . . . subtract 4k
5 = k . . . . . . . . . . . divide by 2
__
The attached graph shows the different scenarios, where the blue line is the son's progress. When the father starts 5 minutes earlier, the son meets him half-way to the factory after 10 minutes, so k = 10/2 = 5.
What number could replace kkk below? \dfrac{k}{100} = \dfrac{1}{10} 100 k = 10 1 start fraction, k, divided by, 100, end fraction, equals, start fraction, 1, divided by, 10, end fraction k={}k=k, equals
Answer:
k = 10Step-by-step explanation:
Given the equation;
[tex]\dfrac{k}{100} = \dfrac{1}{10}[/tex]
We are to find the value of k.
Cross multiply;
[tex]\dfrac{k}{100} = \dfrac{1}{10} \\10 \times k = 100 \times 1\\10k = 100\\[/tex]
Divide both sides by 10
[tex]10k/10 = 100/10\\k = 10[/tex]
Hence the value of k is 10

When Sarah divided a number by 5, the quotient was 247 with a remainder. What is one possible dividend? With a complete sentence, explain how you found the dividend.
Answer:
One possible dividend is 1,237
Step-by-step explanation:
One possible dividend will be 1,237
This is because of we multiply 247 by 5, we get 1,235 and we can add 2 so we can have remainder 2
The difference between the next factor of 5 and the last one which has 247 as the multiple of 5 is 5
So adding 1,2,3 and 4 to the product will give a number that is not up to the next multiple of 5 and thus we can have our dividend with the remainder
Help with congruent angles - please----
State if the 2 angles are congruent.
If they are, state how you know- for example SSS or SAS.
Answer:
No, they are not congruent, see why belowStep-by-step explanation:
The red lines indicate corresponding angles. Here we see 2 corresponding congruent sides and 1 corresponding congruent angle. The SAS postulate states that we can conclude a triangle is congruent if we have 2 sides and 1 angle as being congruent. However, on closer inspection, we will notice that the angle is not actually corresponding. The first triangle has the angle between the two sides marked, but the second one has the angle on the other side marked. Because of this, we cannot conclude the triangles are congruent.
Melissa makes 8 dollars for each hour of work. Write an equation to represent her total pay p after working h hours
Answer:
8 x h= p
Step-by-step explanation:
You see 8. That is the amount she is getting paid for each hour.
p is how much is paid totally after working a certain amount of hours
h represents how many hours she works.
8 dollars times the amount of hours she works(h) would equal p, the total amount she is paid
