Answer:
Equation: [tex]y=-\frac{1}{2} x+20[/tex]
20 represents the y-intercept. It is the initial value.
The slope is -1/2. It means that every gallon of gasoline used is used to shovel 2 driveways.
Mehvish buys 1/2 kg carrots, 3 kg potatoes, 2 kg onions and 1 1/2kg of chicken.
PRICE LIST
carrots: 50p per kg
potatoes: 64 per kg
onions: 42p per kg
Chicken: £6 per kg
She pays with a £20 note.
Work out the change that Mehvish should get.
Answer:
The amount of change will be £7.99
Step-by-step explanation:
Here, we want to calculate the amount of change that Mehvish should get
1/2 kg carrots at 50 p per kg will be;
1/2 * 50 = 25 p
3 kg potatoes at 64 p per kg will be
3 * 64 = p 192
2 kg onions at 42 p per kg
2 * 42 p = 84 p
1 1/2 kg chicken at £6 per kg will be:
since £1 is 100 p
1.5 * 6 = £9 (9 * 100 p = 900p)
since £1 is 100 p
£20 will be;
20 * 100 = 2,000 p
So let us make the subtraction as follows;
2,000- 900 - 84-192 - 25 = 799 p
In pounds, this is divided by 100
we have this as 799/100 = £7.99

single fraction:
2/3a - 1/b + 3/2ab
Answer:
(4b - 6a + 9) / 6ab.
Step-by-step explanation:
The lowest common denominator of 3a, b and 2ab = 6ab
Now to get the numerator we divide each of the 3 denominators into 6ab and multiply the result by the corresponding numerator:
So we have:
2/3a - 1/b + 3/2ab
= (2*2b - 6a +3*3) / 6ab
= (4b - 6a + 9) / 6ab.

Answer:
C= 93⁰, B= 64⁰, D= 23⁰
Step-by-step explanation:
180= (4x + 1) + (3x - 5) + x⁰
180= 4x+1 +3x-5 +x
180= 8x - 4
184= 8x
184/8= x
23=x
therefore
C= (4(23) +1)
C= 93
B= (3(23)-5)
B= 64
D= 23
93⁰+64⁰+23⁰=180⁰

Out of this 80, 75% are offspring from the two previous breeding seasons.
This percentage in a whole number is what the question requires.
The number of offspring from previous seasons is:
= Percent of offspring from previous seasons * Total number of devils
= 75% * 80
= 60 devil offspring.

Tonya is staring a jewelry business. She is going to sell b bracelets for $12.50 each and n necklaces for $22.50. Tonya wants to make at least $800 a month. Which inequality below models this situation? A 12.50n +22.50b≥80012.50n\ +22.50b\geq 80012.50n +22.50b≥800 B 12.50b+22.50n≤80012.50b+22.50n\leq 80012.50b+22.50n≤800 C 12.50b+22.50n≥80012.50b+22.50n\geq 80012.50b+22.50n≥800 D 12.50n+22.50b≤80012.50n+22.50b\leq 80012.50n+22.50b≤800
Answer:
C 12.50b+22.50n≥800
Step-by-step explanation:
Tonya is staring a jewelry business. She is going to sell b bracelets for $12.50 each and n necklaces for $22.50. Tonya wants to make at least $800 a month.
When we use the word at least in Mathematics is means that it is equal to or more than $800.
It is represented by the symbol ≥
Number of bracelets = b
Number of necklaces = n
Therefore, the inequality below models this situation is given as:
$12.50 × b + $22.50 × n ≥ $800
= 12.50b + 22.50n ≥ 800

Marcus took her client out for dinner that costs $157.75 before taxes. If she paid $7.89 on the meal , calculate the tax rate
Answer:
5%
Step-by-step explanation:
A tax is a compulsory sum levied by the government or an agency of the government on goods and services. Taxes raises the price of products
Tax rate is the percentage a person pays as tax
tax rate = [tex]\frac{tax paid}{cost of the dinner}[/tex] × 100
[tex]\frac{7.89}{157.75}[/tex] × 100 = 5%
She paid a tax rate of 5% on the dinner
How many liter of 15% weed killer mixture must be added to 5 liters of 10% weedkiller mixture to make 12% weed killer mixture?
Answer: 3 1/3 liter
Brainliest? <3
let x equal the number of liters of 15% weedkiller.
your equation is .15 * x + .10 * 5 = .12 * (x + 5)
simplify to get .15 * x + .10 * 5 = .12 * x + .12 * 5
simplify further to get .15 * x + .5 = .12 * x + .6
subtract .12 * x from both sides and subtract .5 from both sides and simplify to get .03 * x = .1
divide both sides by .03 to get x = .1 / .03 = 3.333333333 rounded to 9 decimal digits.
you would need 3.333333333 liters of 15% solution to be added to 5 liters of 10% solution to get 8.333333333 liters of 12% solution.
.15 * 3.333333333 = .5
.10 * 5 = .5
.5 + .5 = 1
5 + 3.333333333 = 8.333333333
1 divided by 8.333333333 = .12 which is equal to 12%.
A bakery sells cupcakes for $4.45. They have a special sale on St. Patrick's Day and all cupcakes are 42% off. How much would you pay for a cupcake? Show your work.
remember,show your work
want a brainlist and a thanks:
1-answer the question correctly
2-explain it correctly
3-make sure the explanation is understandable
Answer:
$2.58
Step-by-step explanation:
4.45*0.42 = 1.87
4.45 - 1.87 = 2.58
When you multiply things under 0, but still positive, you get the percentage,
for example 0.42 is 42 percent, 0.50 is 50%, and 0.15 is 15%. Which is why you multiply 0.42 by 4.45, you get 1.87.
4.45 minus 1.87 because,
You have 42% of 4.45, but you need to take 42% off.
Marion bought 14 packages of plastic frog and lizard fishing lures. She bought frog lures in
packages of 4 and lizard lures in packages of 6 for a total of 72 lures. How many of each lure did
Marion buy?
A. 6 lizards and 4 frogs
B. 4 lizards and 8 frogs
C. 48 lizards and 24 frogs
D. 24 lizards and 48 frogs
Answer:
C. 48 lizards and 24 frogs
Step-by-step explanation:
Let F = number of frog lures, and let L = number of lizard lures.
Marion bought 14 packages of plastic frog and lizard fishing lures.
She bought frog lures in packages of 4 and lizard lures in packages of 6 for a total of 72 lures.
F + L = 72
F/4 + L/6 = 14
12 * F/4 + 12 * L/6 = 12 * 14
3F + 2L = 168
(+) -3F - 3L = -216
------------------------------
-L = -48
L = 48
F + L = 72
F + 48 = 72
F = 24
Answer: C. 48 lizards and 24 frogs

You have a roll of 100 feet of tubing and you need to cut 8 ½ foot lengths for IV pumps. How many 8 ½ foot lengths will you get? Will there be any tubing left over? If so, how much?
Answer: 11, 6.5 ft
Step-by-step explanation:
Given
The length of the roll is [tex]100\ ft[/tex]
The length required for a pump is [tex]8\ \frac{1}{2}\ ft=\frac{17}{2}\ ft[/tex]
No of pumps(n) we get
[tex]\Rightarrow \dfrac{100}{\frac{17}{2}}=11.76\ \approx 11[/tex]
length for 11 pumps
[tex]\Rightarrow 11\times \frac{17}{2}=93.5\ ft[/tex]
The remaining length of the tube is
[tex]\Rightarrow 100-93.5=6.5\ ft[/tex]

Write the equation of a line through the point (5,4) that is perpendicular to the line y=-5/3x-2
Answer:
y=3/5x+1 because when a line is perpendicular to another line the slope it the opposite meaning negative to positive or positive to negative
you also reverse the number/ fraction...for example, if the slope was 2 the slope in the other equation would be -1/2. if the slope in the first equation was 1/2 the second equation slope would be -2 since it is the opposite and flipped
