Answer:

It really all depends on how much percent of your grade the test is worth. If your current average is 77%, and the test is worth 30-100% of your grade, then the 77% will likely become 75% or even 73%.

Step-by-step explanation:

It all just depends.

Answer:

Step-by-step explanation:

The rectangle ABCD has vertices A(-2,2), B(6,2), C(6,3) and D(-2,3).

Now, length of side AB = [6 - (- 2)] = 8 units.

{Since the line AB is parallel to the x-axis, so the length of the segment AB will be the difference between the x-coordinates of the points A and B}

Again, line BC is parallel to y-axis and hence the length BC = (3 - 2) = 1 units.

Therefore, the area of the rectangle ABCD will be (8 × 1) = 8 sq. units. (Answer)

Answer:

8 Square Units

I think its 5%

12/240=0.05

0.05=5%

Sorry if its wrong I haven't studied about percentages yet in school

Answer:

5%

Step-by-step explanation:

12/240=0.05

which is 5 percent so 12/240=0.05=5%

Answer:

x - 3.8 = y

Step-by-step explanation:

3.8 - 3.8 = 0

4.2 - 3.8 = 0.4

5.1 - 3.8 = 1.3

7.3 - 3.8 = 3.5

Answer:

[tex]5.11 \times {10}^{3} \\ = 5.11 \times 1000 \\ = 5110[/tex]

Answer:

5110

Step-by-step explanation:

In order to solve this, we need to know what a "power" in math is, and then we just do the following...

[tex](5.11)(10^{3}) = (5.11)(1000) = 5110[/tex]

Answer:

6.65 kilometers

Step-by-step explanation:

950 * 7 days a week = 6650 meters

6650 meters / 1000 (conversion to kilometers) = 6.65 kilometers

Answer:

6.65  km

Step-by-step explanation:

Let's solve this in a set of fraction forms. Since 1 day is 950 meters, 1 week will be converted to days to be on equal grounds. 1 week = 7 days. Therefore, let us set up a fraction; Let "x" be the variable

[tex]\frac{950}{1}=\frac{x}{7}[/tex]

Step 1: Switch sides

[tex]\frac{x}{7}=\frac{950}{1}[/tex]

Step 2: Apply rule [tex]\frac{a}{1}=a[/tex]

[tex]\frac{x}{7}=950[/tex]

Step 3: Multiply both sides by 7

[tex]\frac{7x}{7}=950\cdot \:7[/tex]

Step 4: Simplify

[tex]x=6650[/tex]

Expressed: [tex]\frac{6650 meters}{1000}[/tex] (convertion to kilometers) = 6.65 kilometers

Therefore, Janet would walk 6.65 km in an entire week

Answer:

Step-by-step explanation:

Given :-

To Find :-

We can find the slope of the line passing through the points [tex]( x_1,y_1)[/tex] and [tex]( x_2,y_2)[/tex]as ,

[tex]\implies m = \dfrac{ y_2-y_1}{x_2-x_{1}}[/tex]

[tex]\implies m = \dfrac{ 42-15}{18-7} \\\\\implies \boxed{ m = \dfrac{ 27}{11 }}[/tex]

Hence the slope of the line is 27/11 .

[tex]\rule{200}2[/tex]

Finding the length of AB :-

[tex]\implies Distance =\sqrt{ (x_2-x_1)^2+(y_2-y_1)^2} \\\\\implies Distance =\sqrt{ (18-7)^2+(42-15)^2 } \\\\\implies Distance =\sqrt{ 11^2 + 27^2 } \\\\\implies Distance =\sqrt{ 121 + 729 } \\\\\implies Distance = \sqrt{ 850} \\\\\implies \boxed{ Distance = 29.15 \ units }[/tex]

Hence the length of AB is 29.15 units .

Answer:

Elsa sent 15, Lamar sent 30, and Keith sent 23

Step-by-step explanation:

If x=Elsa, L=Lamar, and K=Keith

2x=L

x+8=K

x+x+8+2x= 68

4x+8=68

4x=60

x=15

Then you plug 15 into x, and solve for each person.

(15)2=L

(15)+8=K

Given:

A regular pentagon with side 14 units and apothem 9.6 units.

To find:

The area round to the nearest tenth.

Solution:

Area of a regular polygon is:

[tex]A=\dfrac{1}{2}Pa[/tex]           ...(i)

Where, P is the perimeter and a is the apothem.

The given figure is a regular pentagon with five sides. So, the perimeter of the given figure is the product of number of sides and the side length.

[tex]P=5\times 14[/tex]

[tex]P=70[/tex]

Putting [tex]P=70,a=9.6[/tex], we get

[tex]A=\dfrac{1}{2}(70)(9.6)[/tex]

[tex]A=(35)(9.6)[/tex]

[tex]A=336[/tex]

Therefore, the area of the regular polygon is 336.0 square units.
