The number of horses on the harm will be 24.
What is an expression?
Expression in math is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Given that;
A local farm raises horses and goats.
The total number of horses and goats on the farm is 96.
Let number of horses = x
Since, The number of goats is 3 times the number of horses.
Then, Number of goats = 3x
The total number of horses and goats on the farm is 96.
Hence, we can formulate;
x + 3x = 96
4x = 96
x = 24
Thus, The number of horses on the harm will be 24.

To convert 81 degrees to radian, we will apply the conversion:

let the 81° in rad = y
1 π rad = 180°
y = 81°
cross multiply:
1π rad (81) = 180 y

The batch of sweet should contain 4 lb of Brand A granola
The batch of sweet should contain 6 lb of Brand B granola
Explanations:Total amount of sweet items = 10 lb
Let the amount of brand A granola be x
Amount of brand B granola = 10 - x
Amount of nuts and dried fruits in the total sweet items = 22% of 10
Amount of nuts and dried fruits in the total sweet items = 0.22 x 10
Amount of nuts and dried fruits in the total sweet items = 2.2lb
Amount of nuts and dried fruits in brand A granola = 25% of x
Amount of nuts and dried fruits in brand A granola = 0.25x
Amount of nuts and dried fruits in brand B granola = 20% of (10-x)
Amount of nuts and dried fruits in brand B granola = 0.2(10 - x)
Amount of nuts and dried fruits in brand A granola + Amount of nuts and dried fruits in brand B granola = Amount of nuts and dried fruits in the total sweet items
0.25x + 0.2(10 - x) = 2.2

What is the probability that a card drawn randomly from a standard deck of 52 cards is a red four? Express your answer as a fraction in lowest terms or a decimal rounded to the nearest millionth.
We have a deck of 52 cards.
We have to calculate the probability that when a card is randomly drawn from the deck, this cart is a red four.
There is only one red four in the deck. Then, if we calculate the probability of an event as the quotient between the number success events (getting a red four, in this case) and the total possible events (getting any card), we will get:
[tex]p=\frac{S}{N}=\frac{1}{52}[/tex]As there is only one card in the deck that gives a success event within the 52 cards, the probability is 1 in 52.
Answer: the probability is 1/52.

Finding Slope
HELP ME PLS
Answer:
-3 because (-1,-7) and (1,-13) takes -6 to get from -7 to -13 and 2 to get from -1 to 1. -6/2 is -3, so the slope/answer is -3.
Step-by-step explanation:
Answer:
Formula for finding slope is given as y2-y1 ÷ x2-x1 or y1-y2 ÷ x1-x2, where x and y are the coordinates of the points.
Slope = -13-(-7) ÷ 1-(-1)
= (-13+7) ÷ (1+1)

Define a variable, used let statements, set up an equation, then solve. Morgan is making two cookie recipes. Recipe A calls for one-third third less than twice the number of cups of sugar that Recipe B calls for. If she needs four and one-sixths cups of sugar in all, how many cups will she need for Recipe A?
EXPLANATION
Let's see the facts:
-Morgan is making ----------------> 2 cookie recipes.
Recipe A ---> A = 2RecipeB -(1/3) 2RecipeB
-She needs-----------> Recipe A + Recipe B = 4 1/6 cups of sugar
Now, we have a system of equations:
(1) A = 2B -(1/3)2B
(2) A + B = 4 1/6
Multiplying both sides of (1) by 3:
3A = 6B - B
Simplifying:
3A = 5B
Isolating B:
B = 3/5 A
Substituting B-value in (2)
[tex]A\text{ + }\frac{3}{5}A\text{ = 4}\frac{1}{6}[/tex]Reordering:
[tex]A+\frac{3}{5}A=\text{ }\frac{25}{6}[/tex]Multiplying both sides by 30:

which of the following is the equation of the line that passes through the point (-3,7) and is parallel to the y-axis.
ANSWER
[tex]x=-3[/tex]EXPLANATION
We want to write the equation of the line that passes through the point (-3, 7) and is parallel to the y-axis.
The general equation of a line is given as:
[tex]y=mx+c_{}[/tex]where m =slope
c = y intercept
A line parallel to the y-axis is a vertical line. The slope of a vertical line is undefined and so the equation of a vertical line is given as:
[tex]x=a[/tex]where a is the x coordinate of any point that it passes through.
Therefore, since the line passes through (-3, 7), the equation of the line is:
[tex]x=-3[/tex]Add.

Which equation represents a line that has a slope of 1/3 and passes through point (-2, 1)? O y=1/3x-1 Oy=1/3x+5/3 O y=1/3 x-5/3 O y=3x+1
Explanation:
The equation of a line in the slope-intercept form is:
[tex]y=mx+b[/tex]Where m is the slope and b is the y-intercept.
We have that the line has a slope of 1/3:
[tex]y=\frac{1}{3}x+b[/tex]To find the y-intercept b we have to use the point. Replace x = -2 and y=1 and solve for b:
[tex]\begin{gathered} 1=\frac{1}{3}(-2)+b \\ 1=-\frac{2}{3}+b \\ b=1+\frac{2}{3}=\frac{5}{3} \end{gathered}[/tex]Answer:

Step 1
let x represents the number of minutes.
hence:
Plan A costs $19 plus an additional $0.07 for each minute of calls
[tex]A=19+0.07x[/tex]Plan B costs $12 plus an additional $0.11 for each minute of calls

[tex]undefined[/tex]6) Write an equation of the line parallel to: y = -1/4x + 8 with a y-intercept of -10.
The given equation is
[tex]y=-\frac{1}{4}x+8[/tex]The y-intercept of the new line is -10.
We have to find a new parallel line to the given equation, which means they must have the same slope.
Remember that the coefficient of x is the slope, so the slope of the given line is -1/4. This means the new line has a slope fo -1/4 because it's parallel.
So, we know that the new line has a slope of -1/4 and its y-intercept is -10. We use the slope-intercept form to write the equation.
[tex]\begin{gathered} y=mx+b \\ y=-\frac{1}{4}x-10 \end{gathered}[/tex]Therefore, the equation is[tex]y=-\frac{1}{4}x-10[/tex]Write a formula for the function of tamed when the graph is shifted as described below
Given the function
[tex]f(x)=|x|[/tex]Then, the function is shifted down 3 units means you subtract 3 to f(x).
[tex]f(x)=|x|-3[/tex]And the function is shifted to the right 1 unit means you subtract 1 from the argument of f(x), this is "x". Therefore, the new function is:
[tex]f(x)=|x-1|-3[/tex]Answer:
[tex]f(x)=|x-1|-3[/tex]Solve the system of equations below to find it's solution. List the x-coordinate and y-coordinate.y = 2x - 56x - 2y= 20
y = 2x - 5 Eq(1)
6x - 2y= 20 Eq(2)
We are going to use the elimination method to solve the system.
y-2x = -5 Transpose x to the othe side in Eq(1)
2y - 4x = -10 Multiply all terms of Eq(1) by 2. Then add Eq(1) to Eq(2)
2y - 4x = -10
+ -2y +6x= 20
----------------------
2x = 10 Operating like terms
x= 10/2 Isolating x
x = 5
Replacing x in Eq(1)
y = 2*(5) -5
y= 10 - 5 = 5
The answer is the point with coordinates ( 5 (x-coordinate) , 5(y-coordinate)).
Measure the angle in degrees.0806100-110120130140150160170-1800The measure of this angle is
The measure of this angle is 65°
The measure of this angle is 60°
Explanation:
1) From the diagram the angle is between 10° and 75°
One of the arrows is on 10°
the other arrow is on 75°
the measure of the angle is between the two angles, so we subtract the smaller one from the bigger one
The angle in degrees is the difference between the 75° and 10°
= 75 - 10
= 65°
The measure of this angle is 65°
2) The second diagram is from 0° to 60°
Difference between them = 60° - 0°= 60°
The measure of this angle is 60°

We are given :
-Cab fare for the first 1/6 mile = $1.10
-subsequent miles = $20
- total miles = 9
Calculations :
• 9 -1/6 = 54/6

Ahmad will rent a car for the weekend. he can choose one choose one of two plans. the first plan has an initial fee of $55 and cost an additional $0.13 per mile driven the second plan has an initial fee of $48 and cost am additional $0.17 per mile driven
SOLUTION
(a) The first plan cost $55 and an additional $0.13 per mile driven,
while the second plan cost $48 and an additional $0.17 per mile driven
Let the amount of driving be x
Then, this means that for the first plan we have
[tex]\begin{gathered} 55+(0.13\times x) \\ =55+0.13x \end{gathered}[/tex]And the second plan becomes
[tex]\begin{gathered} 48+(0.17\times x) \\ =48+0.17x \end{gathered}[/tex]So, for the plans to cost the same for a particular amount of driving x, it means that
[tex]55+0.13x=48+0.17x[/tex]Collecting like terms we have
[tex]\begin{gathered} 55-48=0.17x-0.13x \\ 7=0.04x \\ x=\frac{7}{0.04} \\ x=175 \end{gathered}[/tex]Hence the two plans cost the same at 175 miles
(b) The cost when the two plans cost the same is
[tex]\begin{gathered} 55+0.13x \\ 55+0.13(175) \\ =55+22.75=77.75 \\ Or\text{ } \\ 48+0.17x \\ =48+0.17(175) \\ =48+29.75=77.75 \end{gathered}[/tex]Hence the answer is $77.75
