The teacher asked 4 students to measure 4 different objects. Here are the results
Which student had the greatest percent error?

Answer:

D

Step-by-step explanation:

You know the slope has to be -5, because in the equation it says -5x. You know the y intercept has to be a number on the y axis, and since it says the y intercept is 4 in the equation, you would know its (0,4).

Answer:

B

Step-by-step explanation:

The cylindrical part

Area of the cylindrical part = Circumference of the circle * height

Area of the cylindrical part = pi * d * height

Area = 3.14 * 10 * 9

Area =                                                                                282.6

Lid

Area = pi * r^2

r = 5

Area = 3.14* 5^2 * 2

Area =                                                                                 157

Total                                                                                    439.6                                                                        

I know this doesn't look right according to the diagram, but it is the only way that you can solve the question. That is, you must assume there are two lids, not one as the diagram suggests.

Answer:

7

Step-by-step explanation:

The function is f(x) so if x is replaced with a number, that's the value that x is in the equation. In this case, it'll be -5, so go to -5 on your graph. The y value is 7.

Answer:

9.1 gallons of water.

Step-by-step explanation:

A standard showerhead dispenses 21 gallons of water in 30 mins. At this rate, how many gallons of water will a standard showerhead dispenses in 13 minutes?

30 minutes = 21 gallons

13 minutes = x gallons

Cross Multiply

30 minutes × x = 13 minutes × 21 gallons

x = 13 minutes × 21 gallons/30 minutes

x = 9.1 gallons of water

Therefore, a standard showerhead dispenses 9.1 gallons of water in 13 minutes.

Answer:

$2000

Step-by-step explanation:

The value of the savings account is

v(m) = 2000(1.005)^m

where m is the number of months.

Compare with the formula for compound interest,

F = P(1 + r)^(nt)

where P = principal amount invested.

Answer: $2000

Answer:

1. x= 3y+6/2

y=2/3x-2

2.x=−y+3

y=−x+3

Step-by-step explanation:

1. Let's solve for x.

y=2/3x-2

Step 1: Flip the equation.

2/3x-2=y

Step 2: Add 2 to both sides.

2/3x-2+2=y+2

2/3x=y+2

Step 3: Divide both sides by 2/3.

2/3x/2/3=y+2/2/3

x= 3y+6/2

Let's solve for y.

y=2/3x-2

2. Let's solve for x.

y=−x+3

Step 1: Flip the equation.

−x+3=y

Step 2: Add -3 to both sides.

−x+3+−3=y+−3

−x=y−3

Step 3: Divide both sides by -1.

-x/-1=y-3/-1

x=−y+3

Let's solve for y.

y=−x+3

The correct option is,

⇒ Since the function is even, the outputs of a negative x-value and a positive x-value are the same.

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Since, We know that;

A function is "even" when f(x) = f(−x) for all x.

Now, Geometrically speaking, the graph face of an even function is symmetric with respect to the y-axis, meaning that its graph remains unchanged after reflection about the y-axis.

So, If point (6, 8) is one the points on the graph of f(x),

Then, f (6) = 8

And, since function is even, you can state that;

⇒ f(-6) = f(6) = 8.

This means that point (-6,8) must also be a point on the graph. Geometrically it means that the output of a negative x-value and its opposite is the same.

Thus, The correct option is,

⇒ Since the function is even, the outputs of a negative x-value and a positive x-value are the same.

Step-by-step explanation:

Step-by-step explanation:

3x-9=2x+73

3x-2x=73+9

x=82

Answer:

x = 83

Step-by-step explanation:

3x-9 / 2 = x + 37

1. multiply both sides by 2 to get rid of the fraction

3x - 9 = 2x + 74

2. move the variable to one side and the numbers to another side

3x - 2x = 74 + 9

x = 83

Answer: R=5 D=10

Step-by-step explanation: If I am correct the radius is 5 while the diameter is 10. All you need to do is subtract 7 by 2 ( from the coordinates) giving you five. Now if you multiply 5 by 2 you get 10 which is the diameter. Hope this helps and best of luck.

Answer:

6x+8y = 3

Step-by-step explanation:

we have 3x + 4y = 7

4y = -3x + 7

y = -3/4 x + 7/4

so slope is -3/4

2 parallel lines always have same slope

so the slope of our new line is -3/4

so y = -3/4 x + C

for c,

we have (x,y) = (-2/3,7/8)

7/8 = -3/4 * -2/3 + C

C = 3/8

so equation is

y = -3/4 x + 3/8

simplyfyig,

8y = -6x + 3

or, 6x+8y = 3

Answer:

18 1/5

Step-by-step explanation:

1. First, we can convert all the x's into 3's

Our Equation: 3+1/2 + 15 - 3/10

2. Now we know that 3+1/2 = 3 1/2

Our Equation : 3 1/2 + 15 - 3/10

3. Now, we can add 3 1/2 + 15

Our Equation: 18 1/2 - 3/10

4. Next we can convert 1/2 so that the denominator is 10 and we get 18 5/10

Our Equation: 18 5/10 - 3/10

5. Now, we can subtract 3/10 from 5/10

Our Answer: 18 2/10 or 18 1/5

Answer:

B.

Step-by-step explanation:

Any point in the highlighted (red) region will be in our solution set.

Note that our line is dotted. Thus, any points on the line is not in our solution set.

So, we can simply go through each point and check.

A is on the line. So, A is not a solution.

B is within the red region. Hence, B is our solution.

C is on the line. So, C is not a solution.

And D is not in the red region. So, D is not a solution.

Therefore, our answer is B.

Answer:

rational bc it's a decimal

Step-by-step explanation:

Given:

Principal value = $12000

Rate of interest = 2.5%

To find:

Total amount after 15 years.

Solution:

Formula for amount discontinuously compounded interest is

[tex]A=Pe^{rt}[/tex]

where, P is principal, r is rate of interest and t is time in years.

Substitute P=12000, r=0.025 and t=15 in the above formula.

[tex]A=12000e^{0.025(15)}[/tex]

[tex]A=12000e^{0.375}[/tex]

[tex]A=12000(1.45499141462)[/tex]

[tex]A=17459.8969754[/tex]

[tex]A\approx 17459.897[/tex]

Therefore, the amount after 15 years is $17459.897.
