Answer:
Cos B = 4/5
Step-by-step explanation:
From the question given above, the following data were obtained:
Sine B = 3/5
Cos B =?
Recall:
Sine B = Opposite / Hypothenus
Sine B = 3/5
Therefore,
Opposite = 3
Hypothenus = 5
Next, we shall determine the Adjacent. This can be obtained as follow:
Opposite = 3
Hypothenus = 5
Adjacent =?
Hypo² = Adj² + Opp²
5² = Adj² + 3²
25 = Adj² + 9
Collect like terms
Adj² = 25 – 9
Adj² = 16
Take the square root of both side
Adj = √16
Adjacent = 4
Finally, we shall determine Cos B. This can be obtained as follow:
Hypothenus = 5
Adjacent = 4
Cos B =?
Cos B = Adjacent / Hypothenus
Cos B = 4/5

A car dealership has SUVs and sedans in a ration of 5:9. How many sedans does the car dealership have if there are 140 SUVs
To solve this, all you need to do is compare the ratio to the amount of SUVS there are.
5/9 (SUVs to sedans)
140/? (SUVs to sedans)
140 ÷ 5 = 28
9 x 28 = 252
140/252
There are 252 sedans in the car dealership! :D
Answer:
252 Sedans

Mark's favorite tree is a large oak
tree in his front yard. Mark wanted to
know how tall the tree is. At the
same time of day, he measured the
length of his shadow and the length
of the shadow cast by the tree. Mark,
who is 5 feet tall, cast a shadow 10
feet long. He found that the tree's
shadow was 140 feet long. How tall is
the tree?
Answer: The shadow of the tree is 280 feet long.
Step-by-step explanation:
We can use a ratio to solve this:
Use the Height to shadow for each. This works because the fractions must reduce to the same equivalent.
5/10 = 140/x
We can see that 5/10 is 1/2, so we need another fraction using 140 as the numerator that is equal to 1/2. That's easy here: Multiply 140 × 2 to get the new denominator, 280 that replaces x. That is the length of the shadow.
If you have a less obvious ratio, you can use Cross Multiplication to solve the unknown value in the ratio:
5/10 = 140/x Cross multiply the numerator of the left side times the denominator on the right side, and the denominator on the left side by the numerator on the right side:
5 × x = 10 × 140
5x = 1400 Divide both sides by 5 (the 5s "cancel" on the left)
5x/5 = 1400/5
x = 280
I hope this helps, especially when you see more questions like this in the future.

Imagine that you are given the graph of a brand new parent function, y = P(x), that you have never seen before. You are then asked to graph y = P(x) + 3. Explain how you would go about graphing this new function.
Answer:
You would move each point on y=P(x) up by three. Or add 3 to each y coordinate
Step-by-step explanation:
This is because we're not manipulating the value of x before it gets multiplied by P.
For example:
If x is set to equal 5 and P equal to 2, then the parent function would have a coordinate of (5,10) since 2(5)=10 but the new function would have a coordinate of (5,13) since 2(5)+3= 13 due to order of operations (2×5 =10, then we add 3).
Answer:
Step-by-step explanation:
Step 1:
Plot y=P(x) from x=-a to x=a with x=0 as the middle point of the distance between a and -a.
Step 2:
Add the value of +3 to each point of y=P(x), ie, y=P(x)+3 meaning that the graph y=P(x) will be pulled up three units on the y axis.
Let C represent the cost in dollars and R represent the revenue in dollars. What is the break-even point? Use a table to help if necessary.
C=24x+80
R=44x
Break Even point (_ , _)
Answer:
Please check the explanation.
Step-by-step explanation:
Given
C=24x+80
R=44x
To determine
What is the break-even point?
Given that
C represents the cost in dollars
R represents the revenue in dollars.
At the break-even point Cost (C) equals Revenue (R), so
R = C
44x = 24x+80
44x-24x = 80
20x = 80
divide both sides by 20
20x/20 = 80/20
x = 4
Thus, at x = 4 the value of Cost (C) equals Revenue (R).
i.e.
C = 24x+80 = 24(4)+80 = $176
R = 44x = 44(4) = $176
Answer:
(4, 176)

Consider the division expression 8 divided by 2 create one multiplication problem that relates to this division problem
Answer:
We need to consider the division 8/2.
We know that 1/2 is equal to 0.5, then we just could write a problem where we need to multiply 8 by 0.5, this can be something like:
"You found a box with 8 kittens in it, they are a lot of kittens for you to care, so you decide to give the 50% of them to your friend. How many kittens you end up having?"
Well, there are 8 kittens, which represent the 100%.
how many kittens are the 50%?
We have the equations:
8 kittens = 100%
x = 50%
Take the quotient of these two equations:
x/8 kittens = (50%/100%)
x = (50%/100%)*8 kittens
x = 0.5*8 kittens
and 0.5 = 1/2
then:
x = 0.5*8 kittens = (1/2)*8 kittens
x = 8/2 kittens = 4 kittens.

Radius
314 cm²
Step-by-step explanation:
They gave you the diameter which you can find the radius from, and you need the radius to find the area. The radius is 10, and that squared is 11. Multiply 3.14 times 100 to get 314.

a student throws a baseball with a speed of 8m/s and a kenetic energy of 25J.what is the mass of the baseball
Answer:
25/32 kg
Step-by-step explanation:
The kinetic energy K of a body in motion measured in joules is given as
K = 1/2 mV^2
Where n is the mass in kg and V is the speed in m/s
Hence given that K is 25J and speed V is 8 m/s,
25 =1/2 * m * 8^2
25 = m *32
Divide both sides by 32
m = 25/32 kg

The coach recorded how fast his runners ran 1 mile. Emmett ran a mile in 9.73 minutes Kate ran a mile in 10.87 minutes how many more minutes did Emmett run then Robin
Complete Question
The coach recorded how fast his runners ran 1 mile. Emmett ran a mile in 9.73 minutes, Kate ran a mile in 10.87 minutes, and Rubin ran a mile in 8.46 minutes. How many more minutes did Emmett run than Robin?
a. 1.37 minutes
b. 1.27 minutes
c. 2.27 minutes
d. 1.27 seconds
Answer:
1.27 minutes
Step-by-step explanation:
Emmett ran a mile in 9.73 minutes
Kate ran a mile in 10.87 minutes
Rubin ran a mile in 8.46 minutes.
How many more minutes did Emmett run than Robin?
This is calculated as:
Number of minutes Emmett ran - Number of minutes Rubin ran
= 9.73 minute - 8.46 minutes
= 1.27 minutes

When the equation -3x − 5y = -5 is subtracted from -10x + 5y = -60, a third linear equation, -13x = -65, is formed, and it has a different solution from the original equations.
Answer:
The value of x is 5 and the value of y is -2
Step-by-step explanation:
If the question is to determine the values of x and y, this can be related to the elimination method for solving simultaneous equations.
From the third linear equation, -13x = -65, the value of x can be determined.
-13x = -65
Divide both sides by -13
Then,
-13x/-13 = -65/-13
x = 5
∴ The value of x is 5.
To determine the value of y, the value of x is substituted into any of the first two equations. Say -10x + 5y = -60
-10x + 5y = -60
Substitute x = 5 into the equation
-10(5) + 5y = -60
-50 + 5y = -60
Add 50 to both sides
-50 +50 + 5y = -60 +50
Then,
5y = -10
Divide both sides by 5
5y/5 = -10/5
y = -2
∴ x = 5, y =-2
Hence, the value of x is 5 and the value of y is -2.
16 points!!!!! Ok what is 5+5x2+9999999x6 (5+10)%4
Answer:
224,999,992.5
Step-by-step explanation:
i used the BEDMAS rule.
first of all i added 5+10 which is in the bracket.
then, i multiplied 5×2 because in bedmas rule .. tho division comes first in BEDMAS. we check what is comes first from multiplication and division.
after that . i multiplied 9999999×6 then, as you know. if a digit is before the bracket is multiplied to the digit inside the bracket. i mutiplied the product of 9999999×6 with 15.
i dunno what you meant by (5+10)%4. so i just assumed that you meant (5+10)÷4. after i got the product of 59,999,994 ×15. i divided it with 4. now as we are done with BEDM. now only addition and subtraction is left. there is no subtraction.. so i added the products and the quotient .
Now... add 5+10+224,999,977.5
you get the ans 224,999,992.5
Do correct me if i am wrong.
