If sec θ =25/24, find cot θ.
A. cot θ =10/7 B. cot θ = 24/7
C. cot θ =23/25 D. cot θ = 25/23
Answer:
24/7
Step-by-step explanation:
cos(theta)=24/25
so draw right triangle
you get the length of each side be
7 24 25
(you must draw a picture)
then the answer would be 24/7

yeye bro I got you
Answer:
g x 1.99 + 19.99 OR 1.99g + 19.99
Step-by-step explanation:
The cost is 1.99, you multiply 1.99 by the amount of games you are buying (g) to get the total cost. for example:
1 game = 1.99
2 games = 3.98 -> 3.99 (rounded)
3 games = 5.97 -> 5.99 (rounded)
equation:
(2 games)
1.99 x 3 (amount of games) =
step 2
you just add 19.99 for the membership fee
1.99g also equals 1.99 x g because its algebra.. duh
Find the True statement
Answer:
B. A triangle can have only 1 right angle.
Step-by-step explanation:
Think of a right angle as an L. If you have an L connecting to a backwards L, you have an open shape. Triangles have 3 sides and are closed shapes. If a triangle has two right angles, you could connect the two ends but that would give you a square or triangle.
Hope this helped!
Answer:
B
Step-by-step explanation:
So there can be only one right angle if all other angles are to be greater than zero

At carl's combine diner, there are three size of coffee drinks regular (300ml), large (500ml) and extra large (800mL), and they cost $2.25, $3.25, and $5.75, respectively. on a particular afternoon, the diner sold at total of 37 coffees. The total volume of coffee sold was 19,100mL and the amount of money made in coffee sales was $133.25. How many of each size of drink did customers buy that afternoon?
Answer:
The number of regular, large, and extra-large drinks are 12, 15, and 10 respectively.
Step-by-step explanation:
Given that the cost for regular coffee drinks (300 ml)=$2.25
The cost for large coffee drinks (500 ml)=$3.25
The cost for extra large coffee drinks (800 ml)=$5.75
Let p,q, and r be the number of regular, large, and extra-large coffee sold.
As the diner sold a total of 37 coffees, so
p+q+r=37
r=37-p-q...(i)
The volume of p regular coffee = 300p ml
The volume of q large coffee = 500q ml
The volume of r extra-large coffee = 800r ml
As the total volume of coffee sold was 19,100mi, so
300p+500q+800r=19100
By using equation (i)
300p+500q+800(37-p-q)=19100
300p+500q+800 x 37 - 800p - 800q=19100
-500p-300q=19100-29600
500p+300q=10500
500p=10500-300q
p=21-0.6q...(ii)
Now, the cost of p regular coffee=$2.25p
The cost of q large coffee=$3.25q
The cost of r extra-large coffee=$5.75r
As the amount of money made in coffee sales was $133.25, so
2.25p+3.25q+5.75r=133.25
By using equations (1) we have
2.25p+3.25q+5.75(37-p-q)=133.25
2.25p+3.25q+212.75-5.75p-5.75q=133.25
3.50p+2.50q=79.5
From equation (ii)
3.5(21-0.6q)+2.50q=79.5
73.5-2.1q+2.5q=79.5
0.4q=79.5-73.5=6
q=6/0.4
q=15
From equation (ii)
p=21-0.6(15)
p=12
From equation (i)
r= 37-12-15
r=10
Hence, the number of regular, large, and extra-large drinks are 12, 15, and 10 respectively.
Solve to find the value for x in the linear equation: 3(−4x + 5) = 12.
1. Use the distributive property:
2. Use the subtraction property of equality:
3. Division property of equality:
3(−4x) + 3(5) = 12
−12x + 15 = 12
−12x + 15 − 15 = 12 − 15
−12x = −3
Answer:
Solving the linear equation [tex]3(-4x + 5) = 12[/tex] we get [tex]\mathbf{x=\frac{1}{4}}[/tex]
Step-by-step explanation:
We need to solve to find the value for x in the linear equation: [tex]3(-4x + 5) = 12[/tex]
1. Use the distributive property:
Multiply 3 with terms inside the bracket
[tex]3(-4x + 5) = 12\\3(-4x)+3(5)=12\\-12x+15=12[/tex]
2. Use the subtraction property of equality:
Subtracting 15 on both sides
[tex]-12x+15-15=12-15\\-12x=-3[/tex]
3. Division property of equality:
Divide both sides by -12
[tex]\frac{-12x}{-12}=\frac{-3}{-12}[/tex]
[tex]x=\frac{1}{4}[/tex]
So, solving the linear equation [tex]3(-4x + 5) = 12[/tex] we get [tex]\mathbf{x=\frac{1}{4}}[/tex]
Answer:
x= [tex]\frac{1}{4}[/tex]

Answer:
1a) x = 4
1c) x = 6
1d) x = 10
1f) x = -42
Step-by-step explanation:
1a) 3x -8 = 4
This is a "two step" equation with a variable term and constant on the same side of the equal sign. Step 1, add the opposite of that constant to both sides of the equation:
3x = 12
Step 2: divide both sides of the equation by the coefficient of the variable:
x = 4
__
1c) This is similar to 1a, except that it has variables on both sides of the equal sign. Find the variable term with the smallest coefficient. Here, it is -x, because the coefficient -1 is less than 2. Add the opposite of that term to both sides of the equation:
3x -8 = 10
Now, you have a 2-step equation in the same form as 1a. Solve it the same way.
3x = 18 . . . . add 8
x = 6 . . . . . . divide by 3
Check
2(6) -8 = 10 -(6)
12 -8 = 10 -6
4 = 4 . . . . . true; answer is correct
__
1d) After you eliminate parentheses using the distributive property, you end up with a 3-step equation as in 1c.
6x -12 = 3x +2x -2
6x -12 = 5x -2 . . . . . . combine like terms. (5x is the smallest x-term)
x -12 = -2 . . . . . . . . . subtract 5x
x = 10 . . . . . . . . . . . . add 12
Check
6(10 -2) = 3(10) +2(10 -1)
6(8) = 30 +2(9)
48 = 30 +18
48 = 48 . . . . true; answer is correct
__
1f) You can work this as is using the fractional coefficients. Most folks prefer to "clear fractions" first. To do that, you need to find the least common denominator and multiply both sides of the equation by it. The least common denominator of 1/3 and 1/2 is 6.
2x = 3x +42 . . . . . multiply both sides by 6
0 = x + 42 . . . . . . . subtract the smallest x-term from both sides
-42 = x . . . . . . . . . add -42
Check
(-42)/3 = (-42)/2 +7
-14 = -21 +7
-14 = -14 . . . . . . . true; answer is correct
___
If you work this using the given coefficients, you can subtract 1/3x to get ...
0 = x/6 +7
-7 = x/6 . . . . . subtract 7
-42 = x . . . . . . multiply by 6
You notice that we had to multiply by 6 in the solution process anyway. Doing that first makes the fractions go away, so is often the preferred solution method.

Number 7 (I DONT KNOW THE OTHER ONES)
Step-by-step explanation:
Answer:
There are 19 quarters and 8 dimes.
Step-by-step explanation:
We will let x denote the amount of quarters.
Since there are 27 coins in total, (27-x) will be the amount of dimes there are.
Since each quarter is worth $0.25, the total value of quarters is given by 0.25x.
And since each dime is worth $0.10, the total value of dimes is given by 0.1(27-x).
We know that the total value of all 27 coins is $5.55. So, we can write the following equation:
So, we will determine the value of x, the amount of quarters there are.
First, let’s multiply everything by 100 to remove the decimals. So:
(Distribute)
(Distribute)
(Combine like terms)
(Subtract 270 from both sides)
(Divide both sides by 15)
So, the value of x is 19.
This means that there are 19 quarters.
So, the amount of dimes must be 27-19 or 8 dimes.
Yesterday I drove 150 minutes at a speed of 100 miles/h. How many miles did I drve?
Answer: 250 miles
Step-by-step explanation:
I am not sure what grade level you are, but this is how it is done in college.
I hope it can give you an idea and be of some help.
First you have to convert 150 minutes to hours. Then you multiply your new hours to 100 miles.
150 minutes x 1 hour x 100 miles = 250 miles
60 mins. 1 hour

Complete question :
Chuck lives 4/5 of a mile from the post office. He walked 2/3 of the way from home to the post office. How far did Chuck walk? If possible, write the answer in reduced form
Answer:
8/ 15 miles
Step-by-step explanation:
Given that:
Distance from house to post office = 4/5 miles
Distance walked = 2/3 of the distance
Hence, the distance walked can be obtained thus :
2/3 of (4/5)
2/3 * 4/5
8 / 15
Hence, Chucks walked 8 /15 miles
