Answer:
0.2
Step-by-step explanation:
U need to count how many times it goes up and divide 0.4 by 2
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
if my grade is a 77& and I get a 40% on a test what will my grade be?
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.
Does anyone know what the formula is?
Answer:
29.50 degrees to the nearest hundredth.
Step-by-step explanation:
First we can find the measure of < CGB by using the Cosine Rule:
cos <CGB = (11^2 - 5.3^2 - 6.9^2) / (-2 * 5.3 * 6.9)
= -0.61936
So m < CGB = 128.27 degrees.
Now we can find the measure of x by using the Sine Rule:
11 / sin 128.27 = 6.9 / sin x
sin x = 6.9 * sin 128.27 / 11
= 0.49248
x = 29.5035 degrees
Answer:
x is around 29.5
Step-by-step explanation:
Let's just use the law of cosines.
[tex]c^2 = a^2 + b^2 - 2ab\cos\angle (ab)\\\\6.9^2 = 5.3^2 + 11^2 - 2\cdot5.3\cdot11\cdot \cos x^{\circ}\\47.61 = 28.09 + 121 - 116.6\cdot\cos x^{\circ}\\~\\cos x^{\circ} = \frac{149.09 - 47.61}{116.6} = \frac{101.48}{116.6}\\~\\x^{\circ} = \arccos\frac{101.48}{116.6}\\~\\x^{\circ} \approx 29.5^\circ[/tex]

Write 5.11x10^3 in standard form
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]
Solve the equation. 4(2m – 1) = 16
Answer:
8m-4=16
8m=20
m=2.5
Step-by-step explanation:
Answer:
2.5
Step-by-step explanation:
4(2m -1)/4 = 16/4
2m-1 = 4
2m = 5
m = 5/2 = 2.5

What is the standard form of the equation of a circle with center (3, - 2) and radius 4?
Answer:
(x - 3)² + (y + 2)² = 16
Step-by-step explanation:
The center is determined by what number is subtracted from the variables.
The radius is squared and set equal to the variable side.
PLS HELP!! find area of the shape round to the nearest tenth
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.

Janet walks 950 metres every day. Determine what distance would Janet walk in an entire week. Express your answer in kilometres. (Remember to show your work
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
