Answer:
Answer:
2.215=2 43/200
Step-by-step explanation:
Showing the work
Rewrite the decimal number as a fraction with 1 in the denominator
2.215=2.215/1
Multiply to remove 3 decimal places. Here, you multiply top and bottom by 103 = 1000
2.215/1×1000/1000=2215/1000
Find the Greatest Common Factor (GCF) of 2215 and 1000, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 5,
2215÷5/1000÷5=443/200
Simplify the improper fraction,
=2 43/200
In conclusion,
2.215=2 43/200
Answer:
[tex]\frac{731}{330}[/tex]
Step-by-step explanation:
We require 2 equations with the repeating numbers placed after the decimal point.
let x = 2.2151515... ( multiply both sides by 10 and 1000 )
10x = 22.1515.... → (1)
1000x = 2215.1515.... → (2)
Subtract (1) from (2) thus eliminating the repeating decimal
990x = 2193 ( divide both sides by 990 )
x = [tex]\frac{2193}{990}[/tex] = [tex]\frac{731}{330}[/tex]
Thus
2.2151515..... = [tex]\frac{731}{330}[/tex]

Complementary angles are two angles whose
measures add to 90°. The ratio of the measures of
two complementary angles is 7:11. What are the
measures of the angles?
Answer:
let the two complementary angles be x and 90-x
x= 7t (say)
90-x= 11t
x+90-x=90= 7t+11t=18t
90=18t
t=90/18= 10/2= 5
so x= 7×5=35 degrees
and 90-×=90-35=55 degrees
Answer:
Step-by-step explanation:
Say thanks
mark brainlist
and rate 5!
x= 7t (say)
90-x= 11t
x+90-x=90= 7t+11t=18t
90=18t
t=90/18= 10/2= 5
so x= 7×5=35 degrees
and 90-×=90-35=55 degrees

True or False. To find the missing side length in the diagram, use the Pythagorean Theorem.
Answer: A
Graph this: y = 2sIn(x) - 3
Insert picture of graph
Answer:
We have the function:
f(x) = 2*sin(x) - 3
To graph this type of functions is useful to understand the parts of the function.
A general one is written as:
g(x) = A*sin(w*x + p) + M
where:
A is the amplitude
w is the angular frequency.
p is the phase
M is the midline.
Then in this case we have an amplitude of 2, an angular frequency of 1, a phase of 0 radians and the midline y = -3
Now we can evaluate the function in different points and (knowing how a sine function behaves) connect them, the graph will look something like this:
A triangle has two angle measures of 20 degrees and 30 degrees. Find the third angle. This triangle is a(n) ________ triangle
Question 2 options:
A. acute
B. obtuse
C. right
D. it does not make a triangle
Answer:
Obtuse
Step-by-step explanation:
x = missing angle
20+30+x=180
50+x=180
x=130
90<130
Thus, the triangle is obtuse

What will be the linear equation for the shown table?
Answer:
y=2x+5
Step-by-step explanation:
To find a linear equation you must find the slope and y intercept to create an equation in y=mx+b form (slope-intercept form)
So slope is = y2-y1 / x2-x1 [2 and 1 are subscripts] so 11-7/3-1 so m=4/2 = 2
Slope = 2, now find b
So using y = mx + b, substitute what you know so 7 = 2(1) + b so b=7-2 = 5
Put it all together y = 2x + 5
Brian earns $5 per hour babysitting. He makes a graph and plots what he
earns for different numbers of hours. He places the number of hours he
works on the x-axis and his earnings on the y-axis. What is the slope of the
line that Brian graphs?
Answer:
The slope of the line is 5
Step-by-step explanation:
When we talk of the slope of a straight line graph, we refer to the rate at which the values on the y-axis changes as a ratio of the changes we have on the x-axis
Now, from the question, number of hours is placed on x-axis, while we have the amounts on the y-axis
having $5 per hour means the rate of change of what is earned to number of hours worked is 5 and this is the slope of the line
Find the equation of the linear function represented by the table below in slope-intercept form. The table is in the picture below

The Sugar Sweet Company will choose from two companies to transport its sugar to market. The first company charges $7500 to rent trucks plus an additional fee of $150.25 for each ton of sugar. The second company charges $7143 to rent trucks plus an additional fee of $175.75 for each ton of sugar.
Answer:
14 tons of sugar
$9603.5
Step-by-step explanation:
For what amount of sugar do the two companies charge the same?
What is the cost when the two companies charge the same?
Let
x = ton of sugar
Company A:
7500 + 150.25x
Company B:
7143 + 175.75x
1. Equate company A and company B
7500 + 150.25x = 7143 + 175.75x
7500 - 7143 = 175.75x - 150.25x
357 = 25.50x
x = 357/25.50
x = 14 tons of sugar
2. Cost when both companies charge the same
Company B:
7143 + 175.75x
= 7143 + 175.75(14)
= 7143 + 2460.5
= 9603.5
Company B = $9603.5
Company A:
7500 + 150.25x
= 7500 + 150.25(14)
= 7500 + 2103.5
= 9603.5
Company A = $9603.5

Find the area of the yellow region.
Round to the nearest tenth.
5 ft
Area = [ ? ] ft2
Answer:
yellow area = 5.37 ft²
Step-by-step explanation:
area of square = L x W = 5 x 5 = 25 ft²
radius = 2.5 ft
area of circle = PiR² = (3.14)(2.5²) = 19.63 ft²
25 - 19.63 = 5.37 ft²
The area of the yellow region is 5.375 square feet.
What is area?Area is the amount of space occupied by a two-dimensional figure. In other words, it is the quantity that measures the number of unit squares that cover the surface of a closed figure. The standard unit of area is square units which is generally represented as square inches, square feet, etc.
Given that, the side of a square = 5 feet and radius of a circle = 2.5 feet.
Here, area of a square = side²
= 5²
= 25 square feet
Area of a circle = πr²
= 3.14×2.5²
= 19.625 square feet
So, the area of the yellow region = 25-19.625
= 5.375 square feet
Therefore, the area of the yellow region is 5.375 square feet.

Find x and y in the given figure
Answer:
x= 70°, y=40°
Step-by-step explanation:
2x=140
x= 70
y= 180-140= 40
140 + y = 180
y = 180 - 140
y = 40
2x + 40 = 180 (Angle Sum Property)
2x = 180 - 40
2x = 140
x = 140/2
x = 70
X = 70
Y = 40
PLEASE HELP!! Explain step by step how to graph 2x-3y<18
Answer: Graph the inequality by finding the boundary line, then shading the appropriate area. In slope intercept form its y>-6 + 2x/3. Graph the y intercept -6, then use rise/run and go up 2 points and then to the right 3 points. Then shade the upper right because it is a greater sign and make the lines dashed.

Consider the line 7x+8y=-5.
What is the slope of a line perpendicular to this line?
What is the slope of a line parallel to this line?
Answer:
Step-by-step explanation:
7x + 8y = -5
8y = -7x - 5
Divide the whole equation by 8
[tex]\frac{8y}{8}=\frac{-7x}{8}-\frac{5}{8}\\\\y =\frac{-7}{8}x-\frac{5}{8}[/tex]
Parallel lines have same slope
Slope of the parallel line = (-7/8)
Slope of the line perpendicular to this line = -1/m = -1 ÷ (-7/8)
[tex]= (-1)*\frac{8}{-7}\\\\= \frac{8}{7}[/tex]

A farmer grows x acres of peas and y acres of tomatoes. He has 12 acres available to plant peas and tomatoes. Write an inequality in x and y to satisfy this condition. The number acres of tomatoes planted must not be more then twice the number of acres of peas planted. Write an inequality in x and y to satisfy this condition.
Answer:
Y < 2X
Step-by-step explanation:
Let the acres of land on which pea is to be cultivated is "X" acres and the acres of land on which tomato is to be cultivated is "Y"
It is given that number acres of tomatoes planted must not be more then twice the number of acres of peas planted
Thus, [tex]Y < 2X[/tex]
[tex]X + Y = 12[/tex] acres
[tex]Y = 12-X[/tex] acres
Thus,
[tex]12 - X \leq X\\12\leq 2X\\6 \leq X[/tex]
Let us take X = 6 , Then Y = 13-6 = 6
