Answer:
90
Step-by-step explanation:
a triangle's angles all add up to 180. take 51 and 39 away from 180 and you get 90
Answer: 90 degrees
Step-by-step explanation:
Theorem:
a+b+c=180 degrees
39 degrees + 51 degrees + x degrees = 180 degrees
39 + 51 = 90
180 - 90 = 90
What is Becca’s speed in miles per hour?
Answer:
1.5 OR 1 1/2
Step-by-step explanation:
Convert the fractions into decimals.
9/10 = 0.9
3/5 = 6/10 = 0.6
Divide the decimals.
0.9/0.6 = 1.5
Convert back to fraction.

Find the slope on the line
Answer:
Zero slope
Step-by-step explanation:
Answer:
1.3
Step-by-step explanation:
Solve this system
5x – 4y + 2z = 21
-x - 5y + 6z=-24
--x – 4y + 5z =-21
O x = 5, y = -1, z = -4
0 x = 1, y = 5, z = -4
O x=-5, y = 1, z = -4
O x = -4, y = -1, z = 5
Answer:
Its the first option
Step-by-step explanation:
Convert the following equation to Slope-Intercept Form
HINT: Slope-Intercept Form is y = mx + b
y-8= 3(x + 5)
Answer:
y = 3x + 23
Step-by-step explanation:
Given the equation :
y - 8 = 3(x + 5)
We are to convert the equation to slope - intercept form:
Recall: general form of a slope - intercept model:
y = mx + c
Hence,
y - 8 = 3x + 15
y = 3x + 15 + 8
y = 3x + 23
Comparing :
y = mx + c
y = 3x + 23

What’s the answer to m/3-2m/5=1/5
Answer:
m = - 3
Step-by-step explanation:
[tex]\frac{m}{3} - \frac{2m}{5} = \frac{1}{5}[/tex]
It is much easier to work with whole numbers, compared to fractions, hence one should remove the denominator of the fraction. This can be done by multiplying by the LCM (least common multiple). In this case, it is fairly obvious that the LCM of 3 and 5 is 15. Therefore multiply the entire equation by 15.
[tex]15*\frac{m}{3} - 15*\frac{2m}{5}=15*\frac{1}{5}[/tex]
Simplify
[tex]5m-6m=3[/tex]
[tex]-m=3\\m=-3[/tex]

Water along the Mississippi River is rising at a rate of 24.8 cm/hr. The top of a dock in the river currently sits only 1.2 meters above the water. How many hours will it take the water to reach the top of the dock
Answer:
4.84*10^-4hoursStep-by-step explanation:
Speed = Distance/Time
Time = Distance/Speed
Given
Distance = 1.2m = 0.012cm
Speed = 24.8cm/hr
Get the time;
Time = 0.012/24.8
Time = 4.84*10^-4hours
Hence it will take the water 4.84*10^-4hours to reach the top of the dock

A saving account earns 4.5 simple interest per year. If 650.00 is deposited and no withdrawals or deposits are made during one year how much interest will be earned after one year
Answer:
29.25 Interest
Step-by-step explanation:
Take the formula: I=PRT
The principal is 650.00, 4.5 is the rate, 1 year is the time, We do not know the interest.
Change the rate, 4.5 to 0.045 to help solve the problem.
Times 650.00, 0.045, and 1 together.
You will get 29.25, Which is the answer!
Booyah! You are done.
Hope this helps!

Answer:
Step-by-step explanation:
If we define the line QR to be some variable of distance 'x', we can use the relationship of cosine to figure out the length of QR.
Remember, cosine is adjacent of the angle divided by the hypotenuse of the angle. So, if we take this x value over the longest side (hypotenuse), we get the value of cos(theta).
cos(25) = x/7
Multiply both sides by 7 to get:
7*cos(25) = x
Let your calculator do the work to get:
x = 6.3

Piper opened a savings account with $1400 that pays no interest. She deposits an
additional $50 each week thereafter. How much money would Piper have in the
account 47 weeks after opening the account?
Answer: Piper will have $3750
Step-by-step explanation:
In this situation we will represent the total amount she have in the bank by y and the number of weeks by x
The whole situation can be represented by the the equation
y = 1400 + 50x where y is the total amount , 1400 is the initial amount Piper deposited , 50 is of course the amount Piper will deposit each week , and x is the number of weeks.
Now since they are looking for the amount Piper will have in his account, you have to input 47 for x and solve for y.
y = 1400 + 50(47)
y = 1400 + 2350
y = 3750
