1-answer correct
2-explain correctly
3-be first to answer(this makes the chance higher for you to get the brainlist)
Answer: $48.06
Step-by-step explanation:
Simply take the sales price minus the unit cost, and divide that number by the unit cost. Then, multiply by 100 to determine the markup percentage. For example, if your product costs $50 to make and the selling price is $75, then the markup percentage would be 50%: ( $75 – $50) / $50 = . 50 x 100 = 50%.
Answer:
You would pay $48.06
Step-by-step explanation:
27*0.78 = 21.06
27 + 21.06 = 48.06
A bike trail is drawn on a coordinate system. Each end of the trail is an x-intercept. The height of the trail is modeled by the function h(x) = -0.1x^2 - 0.3x +2.8 , where x is the horizontal distance in kilometers. How many meters is the horizontal distance of the trail?
Answer:
4metres
Step-by-step explanation:
Given the height of the trail modeled by the function h(x) = -0.1x^2 - 0.3x +2.8 , where x is the horizontal distance in kilometers
The horizontal distance occurs at the x intercept i.e at h(x) = 0
Substitute
0 = -0.1x^2 - 0.3x +2.8 ,
Multiply through by -10
0 = x^2 + 3x - 28
x^2 + 3x - 28 = 0
Factorize
x^2 + 7x - 4x - 28 = 0
x(x+7) - 4 (x+7) = 0
(x-4)(x+7) = 0
x-4 = 0 and x+7 = 0
x = 4 and -7
Since the danced cannot be negative, hence the horizontal distance of the trail is 4m
What is the principal which would amount to $6900 in 3 years at 5% simple interest per annum?
Answer:
$6000
Step-by-step explanation:
accumulated amount = A = PI
A = $6900
Let P = x
6900 - I = x
I = (x)(0.05)(3yrs) = 0.15x
6900 - 0.15x = x
Add
6900 = 1.15x
Divide, solve for x
x = 6000
Cece is finding the surface area of a square pyramid by finding the sum of the areas of its faces. Which statement best describes the faces of the pyramid?
A)one square and three triangles
B)one square and four triangles
C)three squares and one triangle
D)three squares and two triangles
Answer:
D. One square and four triangles
Step-by-step explanation:
Cece is finding the surface area of a square pyramid by finding the sum of the areas of its faces
Square pyramid has a square base.
each edge of the square base joins at the top of the vertex to make a pyramid
The sides of the pyramid is a triangle
the square has 4 sides, so four triangle on the sides of the pyramid
Hence one square and four triangles forms a square pyramid
Answer:
The answer is A). one square and three triangles

whats the answer to 5+ -5
Answer:
The answer is Zero.
Step-by-step explanation:
Adding a negitive 5 to a positive 5 cancels out
Answer:
0
Step-by-step explanation:
It's a negative five, meaning that if you are adding it, the number will still go back.
You made $5, but you're in debt of $5. So even though it is supposed to go up, it goes down back to 0 due to the debt, which is the negative.

FIRST CORRECT ANSWER GETS BRAINLIEST - 100 POINTS
Answer:
110cm
Step-by-step explanation:
With the slice, we know that we need to find the area of a triangle with a base of 10cm and a height of 22cm.
Let 10 be x and 22 be y.
Substitute this into the equation for finding the area of a triangle.
[tex]\frac{x*y}{2}[/tex]
Which now becomes
[tex]\frac{11*20}{2}[/tex]
Which now becomes
[tex]\frac{220}{2}[/tex]
Now solve.
[tex]\frac{220}{2} = 110[/tex]
Your answer is 110cm.

1/2 Square equals to 1/4 equals to x over 5 2 Square
therefore 1/4 equals to x over 5 2 square
Equals to 1/4 equals to x over 5 * 4 you know that 2 square equals to 4
So now I'm going to solve for 1/4 equals to x of over 5 * 4 equals to 20
1/4 equals to x over 20
1/4 equals to 20 cross multiply
= 1\4 = x/20
= 4 * x = 20*1
4x = 20
divide both side by the coefficient of x
4x/4 = 20/4
x =5

A bag contains 324 sweets Amelia takes 1/9 of the sweet from the bag the remaining sweets are divided between Isabella and Olivia in the ration 1:5 how many sweet dose Olivia have ?
Answer:
Olivia has 240.

Amelia took 36 and there were 288 left over. A ratio of 1:5 with 288 would be 48 and 240 so therefore, Olivia has 240.
A hike starts at an elevation of 13 and four-fifths feet below sea level and ends at an elevation that is 1,542 feet higher. How high is the hiker, in feet, above sea level at the end of the hike?
Answer:
the height above the seal level at the end of the hike is [tex]1528 \frac{1}{5} feet[/tex]
Step-by-step explanation:
The computation is shown below:
[tex]= 1542 - 13 \frac{4}{5}\\\\= 1542 - \frac{69}{5}\\\\= \frac{7710-69}{5} \\\\= \frac{7641}{5}\\\\= 1528 \frac{1}{5} feet[/tex]
Hence, the height above the seal level at the end of the hike is [tex]1528 \frac{1}{5} feet[/tex]

Slope intercept form of 4x+4y=-32
Answer:
y = - x - 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
4x + 4y = - 32 ( subtract 4x from both sides )
4y = - 4x - 32 ( divide all terms by 4 )
y = - x - 8 ← in slope- intercept form
Answer:
x+y=-8
Step-by-step explanation:
-32=4x+4y
-4y=4x+32
y=(4x+32)/-4
y=-x-8
x+y=-8
Now comparing to slope intercept form
y=mx+c,we get
slope =1
y intercept =1
y=-8

Read the following situation:
There are 13 animals in the barn. Some are chickens and some are pigs. There are 40 legs in all. How many of each animal are there?
When setting up the system, what could the variables represent? Select all that apply.
Total number of chicken legs
Total number of pigs
How long until the number of pigs and chickens are equal.
How many animals in the barn
Total number of pig legs
Total number of chickens
Where the lines cross
Answer:
Hi, let's turn the word problem into a set of equations:
Let's say that x = # of chickens, and y = # of pigs
If there are 13 animals altogether, that means that
x + y = 13
If there are 40 legs together, we know that chickens have 2 legs, while pigs have 4, so the total number of legs would be:
2x + 4y = 40
We now have two different equations, with the same two variables, so we can rearrange and substitute one equation into the other to solve. We can rearrange the first equation as:
x + y = 13
x = 13 - y
Let's plug this expression for "x" into the second equation:
2(13-y) + 4y = 40
Now we have an equation with only one variable, so we can use algebra to solve for y:
26 - 2y + 4y = 40
2y = 14
y = 7, there must be 7 pigs.
From the first equation that we rearranged,
x = 13 - y
Now that we know the numerical value of "y", we can plug that in:
x = 13 - 7
x = 6, there must be 6 chickens
