what is Evaluate 4/5-3/7
Answer:
[tex] \frac{13}{35} [/tex]
Step-by-step explanation:
To add or subtract two or more fractions from each other, the denominators have to be the same. To make the denominators the same, we should find the least common multiple of 5 and 7. The least common multiple of 5 and 7 is 35. 5 should be multiplied with 7 to get 35 and 7 should be multiplied with 5 to get 35 (with both numerators).
[tex] \frac{4}{5 } - \frac{3}{7} [/tex]
[tex] \frac{4 \times 7}{5 \times 7} - \frac{3 \times 5}{7 \times 5} [/tex]
[tex] \frac{28}{35} - \frac{15}{35} [/tex]
[tex] \frac{13 }{35} [/tex]
When subtracting, only subtract the numerators (the denominators are kept as is).

To boil rice, start by combining water and rice in a pot at a ratio of 3:1. How many cups of water are need for a batch that uses eight cups of rice?
Answer:
Step-by-step explanation:
To boil rice you use the following ratio
Water : Rice
3 : 1
? : 8
Basically what the ratio 3:1 means is that for every 3 cups of water, you need 1 cup if rice.
6 cups of water, you need 2 cups of rice (6:2)
9 cups of water, 3 cups of rice (9:3)
Etc.
All you would have to do is multiply 3 by 8 to find out how much water she needs for 3 cups of rice :)
Answer:
ok the ratio of water to Rice is 3:1 meaning water is 3 rice is one and your child that we have 8 cups of rice so really quite the ratio of rice to the number of cups of rice so it will be if one is equals to 8 what about 3 that is the ratio that represents water so we'll cross multiply so that you have 3 * 8/1 and the answer is 24 so the number of cups of water needed is 24

In the figure shown, FG is tangent to circle D.
DO
G
What is the relationship between DG and FG?
O A. DG is parallel to FG
O B. DG is perpendicular to FG.
OC DG Intersects FG to form an acute angle.
ODDO intersects FG to form an obtuse angle
Answer:
Option B
Step-by-step explanation:
From the figure attached,
Circle D is drawn with the radius = DG or DE
A tangent FG has been drawn at a point G on the circle from an external point F.
By theorem,
Radius of a circle is always perpendicular to the tangent, drawn to the circle from an external point.
Therefore, DG ⊥ FG.
Option B will be the correct option.

What is the slope of a line perpendicular to the line whose equation is
12x – 3y = 81. Fully reduce your answer.
Answer:
slope of perpendicular line is -1/4
Step-by-step explanation:
slope of standard equation of line that is ax+ by = c is
slope m = -a/b
given equation is
12x – 3y = 81
comparing it with ax+ by = c
a = 12
b = -3
thus
slope of given line = -12/-3 = 4
we also know product of slope of two perpendicular line is -1
let the slope of other line be m
thus,
product of given line line and perpendicular line is -1
4*m = -1
m = -1/4
Thus,
slope of perpendicular line is -1/4
Don claims that perpendicular lines are lines that intersect such that at least one of the angles is a right angle.
Determine whether each statement below justifies the claim. Select Yes or No for each statement.
Yes No
Intersecting lines allow for the creation of four angles with a common vertex.
O OD
If one of the angles is a right angle, the angle vertical to it must also be a right angle.
Because linear pairs are complementary, the remaining two angles must also be right angles. O

Answer:
A. 1.88
Step-by-step explanation:
In less fancy terms, a constant of proportionality is essentially a rate of change - or more specifically, a unit rate.
It's the number we multiply our independent variable by to get the y. You can find this by simply dividing the y value by the x value!
Let's choose the first order pair (2, 3.76).
[tex]3.76 \div 2 = 1.88[/tex]
We can check that this table IS constant by doing the same with the other values... we should always get 1.88!
[tex]7.52 \div 4 = 1.88\\9.40 \div 5 = 1.88\\15.04 \div 8 = 1.88[/tex]
This is true for all values - which means our constant is 1.88

Write the slope-intercept form of the equation of the line described.
Through (-2, -1) and parallel to y=-2x-1
Answer:
y= -2x -5
Step-by-step explanation:
Slope-intercept form:
y= mx +c, where m is the slope and c is the y-intercept.
Parallel lines have the same slope.
Thus, to find the value of the slope of the line, we have to find the slope of the given line.
y= -2x -1
Since the coefficient of x is -2 and the equation is already in slope-intercept form, the slope of the given line is -2.
Substitute m= -2 into the equation:
y= -2x +c
To find the value of c, substitute a pair of coordinates.
When x= -2, y= -1,
-1= -2(-2) +c
-1= 4 +c
c= -1 -4 (-4 on both sides)
c= -5
Thus, the equation of the line is y= -2x -5.
If my function rule is 2x + 1, what is the OUTPUT if the input is 2?
Work Shown:
x = 2 is the input

y = 5 is the output
A function is a relationship between inputs where each input is related to exactly one output.

What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:

Input = 1
Output = 5
2.

Old Man Withers just died. He left his collection of baseball cards to his two sons. Bill got 55% of the collection and his brother Bob received the rest.
How many cards did Bill receive if Bob received
360 cards, then how many cards did Bill as inheritance from his father?
Answer:
Step-by-step explanation:
Bill = 55% of the entire collection
Bob = 45% of the entire collection (Since we know 100 - 55 = 45)
We are also told that Bob received 360 cards.
This means that 45% = 360 cards.
First step is to find how many cards is 1%. To do this, divide 360 by 45.
1% of entire collection = [tex]\frac{360}{45} = 8[/tex] cards
This means that since Bill gets 55% of the entire collection, you multiply 8 by 55.
Bill = 8 x 55 = 440 cards.

440

Answer:
1) A = 80
2) A = 30
Step-by-step explanation:
1) x+50 + 80 + x + 70 = 180
2x+120 = 180
2x = 60
x=30
A = (30) + 50
A = 80
2) x+40 + x+90 + (180-110) = 180
x+40 + x+90 + 70 = 180
2x + 200 = 180
2x = -20
x = -10
A = (-10) + 40
A = 30

Step 2:
Step 1: Add 3x to both sides to get 4 = 3x - 1
Step 2: Add 1 to both sides to get 5 = 3x
Step 3: Divide by 3 on both sides to get 5/3 = x

x = [tex]\frac{5}{3}[/tex] or [tex]1 \frac{2}{3}[/tex]
Step-by-step explanation:
Isolate the variable x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and stands for:
Parenthesis

Multiplication
Division
Addition
Subtraction.
~
Step 1:
Subtract 4 from both sides of the equation:
4 (-4) - 3x = -1 (-4)
-3x = -1 - 4
-3x = - 5
Step 2:
Divide -3 from both sides of the equation:
(-3x)/-3 = (-5)/-3
x = -5/-3
x = 5/3
x = 1 2/3
