Answer:
C
Step-by-step explanation:
All numbers in scientific notation or standard form are written in the form m × 10n, where m is a number between 1 and 10 ( 1 ≤ |m| < 10 ) and the exponent n is a positive or negative integer.
Therefore, the decimal number 0.00067 written in scientific notation is 6.7 × 10-4.

Answer:
1) x = 50 m
2) Max area = 22500 m²
3) Max area of each pen = 1500 m²
4) y = 150 m
5) dimensions of pen are 50m and 30m
6) Graph is attached
Step-by-step explanation:
Area of a rectangle is length × width
Let length be y and let width be x
Thus;
A = xy
Fencing material is 600m
Thus,perimeter = 600
Perimeter is; P = 6(length) + 2(width)
Thus;
600 = 6x + 2y
y = (600 - 6x)/2
y = 300 - 3x
Thus,
A = x(300 - 3x)
A = -3x² + 300x
We can see that the coefficient of x² is negative. This means that the parabola will open downward and has a maximum value at the vertex.
The vertex formula is;
x = -b/2a
a = -3
b = 300
Thus;
x = -300/(2 × -3)
x = 50 m
Since y = 300 - 3x, then;
y = 300 - 3(50)
y = 150 m
Maximum area of entire garden = xy = 50 × 150 = 7500 m²
There are 5 pens, thus;
Max area of each pen = max area of entire garden/5 = 7500/5
Max area of each pen = 1500 m²
Dimensions of each pen will be;
x and y/5
>> x = 50 m and y/5 = 150/5 = 30m
Bryson is painting kitchen stools. Each stool requires 1 1/2 liters of paint. Bryson has 20 liters of paint, How many stool will he be able to paint?
Answer:
3
Step-by-step explanation:
5.5 litres paint needed for 1 stool
1 litres paint needed for 1/ 5.5
20 litres paint needed for 20/5.5
= 3.636
And now comes the twist, you can't paint 3.6 stools. also You can't paint 4 stools. You need to round down to 3
Find the average rate of change of g(x) =-x²+2x+2 from x=2 to x = 6.
Simplify your answer as much as possible.
Solve the equation replacing x with 2 and the 6:
-2^2 + 2(2) + 2 = 4 + 4 + 2 =10
-6^2 + 2(6) + 2 = 36 + 12 + 2 = 50
Difference between the answers: 50-10 = 40
Difference between 2 and 6 = 6-2 = 4
Average rate of change = 40/4 = 10
The answer is 10

Choose the function whose graph is given by:
2. Dwayne scored 55 points in the last basketball game, which is 10 points more than his previous personal best. Lebron scored 15 points more than Chris in the
same game. Lebron scored the same number of points as Dwayne’s previous personal best.
Write two algebraic equations, let d represent the number of points Dwayne scored during his previous personal best and c represent the number of Chris’s points.
Answer:
Required equations are:
d + 10 = 55c + 15 = dSolving the first, we get:
d = 55 - 10d = 45Solving the second we get:
c + 15 = 45c = 45 - 15c = 30Which model represents 1.56+0.33
Pls pls help me
Answer:
Model 2
Step-by-step explanation:
1.56 + 0.33 = 1.89
find CE 14 6 x - 5 2x + 3
The value of x from the similar triangles is x = 9 and the length of CE of the triangle ACE is CE = 35
What are similar triangles?If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.
Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides
Given data ,
Let the first triangle be represented as ΔACE
Let the second triangle be represented as ΔBDC
The measure of side AB = 6
The measure of side BC = x - 5
The measure of side AC = x + 1
The measure of side CD = 14
The measure of side DE = 2x + 3
The measure of side CE = 2x + 17
Now , ΔACE and ΔBDC are similar
So , the corresponding sides of similar triangles are in the same ratio
Substituting the values in the equation , we get
AC / CE = BD / CD
( x + 1 ) / ( 2x + 17 ) = ( x - 5 ) / 14
On simplifying the equation , we get
14x + 14 = 2x² - 10x + 17x - 85
Subtracting 14x + 14 on both sides of the equation , we get
2x² - 7x - 99 = 0
On factorizing the equation , we get
x = 9 or x = -11/2
Substituting the value of x in the equation , we get
The length of line segment CE = 2x + 17
The length of line segment CE = 2 ( 9 ) + 17
The length of line segment CE = 35
Hence , the length of CE is 35

Joe designs a weighted number generator that produces the integers 0 to 4. He then run the generator 500 times. The results are shown in the table. If Joe runs a generator a total of 4000 times, which is the closest to the expected number of times to integer for is produced?
Answer: since there is no table shown you can’t really tell but the closest would be the number that shows up the most amount of time but you would have to take into consideration of the increase of the number

(c) Rashid has 210g of cocoa powder and plenty of the other ingredients.
He says that he can make at least 75 cupcakes.
Is he correct?
Explain your reasoning.
Answer:
He is incorrect. He would need 225g of cocoa powder
Step-by-step explanation:
1. Lets calculate how much powder do we need per one cupcake, so 60 divided by 20, since 60g makes 20 cupcakes, 60/20 = we get 3g of cocoa powder per one cupcake.
2. Now we can multiply that by 75, 75*3=225, and 225g is more than 210g

Answer:
There are 42 dogs and 105 cats at the shelter. To find the number of rabbits, subtract these numbers from the total number of animals at the shelter. So there are 21 rabbits at the shelter.
Step-by-step explanation:
Because there are 168 animals at the shelter and [tex]\frac{1}{4}[/tex] of the animals are dogs, you can infer that there are [tex]\frac{168}{4}[/tex] or 42 dogs at the shelter. The question says that [tex]\frac{5}{6}[/tex] of the remaining animals are cats, which you can get two things from this statement: #1, [tex]\frac{5}{6}[/tex] of the remaining animals (not including dogs) are cats in the shelter. #2, [tex]\frac{1}{6}[/tex] of the remaining animals (not including dogs) are rabbits in the shelter, since that is the remaining number of animals left that aren't cats or dogs. Using this, you can get the number of cats is the number of dogs subtracted by the total number of animals at the shelter and multiplied by [tex]\frac{5}{6}[/tex], which would be [tex]\frac{5}{6}[/tex](168 - 42) = [tex]\frac{5}{6}[/tex]*126 = 5 * 21 = 105 cats at the animal shelter. Since the number of rabbits is [tex]\frac{1}{5}[/tex] the number of cats in the shelter ([tex]\frac{5}{6}[/tex] = [tex]\frac{1}{6}[/tex] * 5), that means there are [tex]\frac{105}{5}[/tex] or 21 rabbits at the animal shelter, and that we'd need to subtract the number of cats and dogs from the total number of animals at the shelter to find the number of rabbits.

Answer:
150°
Step-by-step explanation:
The rule here is that the external angle is half the difference of the arcs subtended. That relation is used to form an equation, which can then be solved for whatever measure is of interest.
