Answer:
-33/8= -4 1/8= -4.125
Step-by-step explanation:
step 1: Add (-1 7/8) + (-2 1/4)= -33/8
Step 2: convert the mixed number to improper fraction
− 1 7/8 = (1x8/8 + 7/8) = - 8+7/8 = -15/8
Step 3: Add a negative
-15/8 +(-9/4) = -15/8 - 9/4
Adding a negative is the same as subtracting a positive btw
step 4: Find the common denominator
-15/8 - 9/4 = -15x1/8x1 - 9x2/4x2 = -15/8 -18/8
8 is the least common multiple of denominators 8 and 4. Use it to convert to equivalent fractions with this common denominator.
step 5. Simplify
-33/8 = -4 1/8
A. Simplify, sub-step a: Reduce fraction to lowest terms.
Reduce fraction to lowest terms
1 is the greatest common divisor of 33 and 8. The result can't be further reduced.
B. Convert improper fraction to mixed number
-33/8 = 04 1/8
33 ÷ 8 = 4 remainder 1
Answer:
The solution is -4 1/8 or -33/8
Step-by-step explanation:
[tex] \sf - 1\frac{7}{8} + ( - 2 \frac{1}{4} ) \\ \\ = \sf - \frac{15}{8} - \frac{9}{4} \\ \\ = \sf \frac{ - 15 - 9(2)}{8} \\ \\ = \sf \: = \frac{ - 15 - 18}{8} \\ \\ = \sf - \frac{33}{8} \\ \\ = \sf - 4 \frac{1}{8} [/tex]

Joanna ran a mile in physical education class after resting for 1 hour her heart rate was 60 beats per minute if her heart rate decreased it by 2/5 what was her heart rate and merely after she ran the mile
Answer:Since 2/5 is basically a part of a whole, you would have to divide 60 by 20. You would get thirty. Thirty times five is 150.

Write formula for f(x) in slope intercept form
Answer:
f(x) = 1000x + 3000
Step-by-step explanation:
the point (0,3000)
p2 (1,4000)
slope = (y2-y1) / (x2-x1)
= (4000 - 3000) /( 1-0)
slope = 1000 = m
y = mx + b
y=1000x + b
Use one of the points to find b :
3000 = 1000(0) + b
b = 3000
f(x) = 1000x + 3000

If a and b must be positive integers, what is the largest integer n such that 13a + 18b = n has no solutions?
Answer:
234
Step-by-step explanation:
By Euclidean Algorithm on 13 and 18, we found that 13(7)+18(−5)=1.
Then we multiply the equation by n, we got
13(7n)+18(−5n)=n.
Thus 13(7n)+18(−5n)=n always has integer solution.
However, a and b must be positive integers. So we need to reduce 7n and increase -5n
to make them positive. Noting that13(18m)=18(13m)∀m∈Z.
⇒13(7n−18m)+18(−5n+13m)=n⋯(1)
Let a=7n−18m and b=−5n+13m.Since a and b are positive integers, we have two inequalities:
7n−18m>0 and −5n+13m>0
⇒5n13<m<7n18⋯(2)
In order to make 13a+18b=n has no solutions,n must be taken to make (2) is impossible.
That means there exists no such integer m lying in the interval (5n13,7n18).
As a consequence, the difference between
5n13 and 7n18 must not greater than 1.
7n18−5n13≤1⇒n13×18≤1⇒n≤234.
Let’s put the largest candidate n=234 into (2), we get 90<m<91 ⇒ m is not an integer, which is a contradiction!
Therefore the largest integer n to make 13a+18b=n has no positive integer solutions is 234.

In the diagram, what is mAngleVSR?
2 lines intersect. A horizontal line has points R, S, U and intersects a line with points V, S, T at point S. Angle V S U is 100 degrees.
mVSR =
The measure of m∠VSR if the horizontal line has points R, S, U and intersects a line with points V, S, T at point S is 80degrees
The point where two lines intersect is known as an angle.
Find the diagram to the question attached below.
From the diagram shown, we can see that the angle m∠VSR and m∠VSU lie on the line RSU which shows that the sum of these angles is supplementary. Hence:
m∠VSU + ∠VSR = 180
Given that m∠VSU = 100 degrees
∠VSR = 180 - ∠VSU
∠VSR = 180 - 100
∠VSR = 80degrees
Hence the measure of m∠VSR if the horizontal line has points R, S, U and intersects a line with points V, S, T at point S is 80degrees

A piece of work takes 20 labourers to complete in 10 days. how many labourers will complete the same job in 25 days if they work at the same rate?
Step-by-step explanation:
If 20 labourers=10 days
x labourers = 25 days
10x= 25×20
[tex] \frac{10x}{10} = \frac{25 \times 20}{10}[/tex]
Cancelling out by 10 on both sides
[tex]x = \frac{25 \times 2}{1} \\ x = 50 [/tex]
Therefore, it takes 50 labourers to complete the work at the same rate in 25 days.

Given the complex number z=6(cos120+isin120), find z3
Answer:
B
Step-by-step explanation:
We are given the complex number:
[tex]\displaystyle z = 6(\cos 120^\circ + i\sin 120^\circ)[/tex]
And we want to find z³.
Recall that:
[tex]\displaystyle z^n = r^n(\cos(n\theta) + i\sin (n\theta))[/tex]
In this case, n = 3. Hence:
[tex]\displaystyle z ^3 = (6)^3 (\cos (3(120^\circ)) + i\sin (3(120^\circ))[/tex]
Simplify:
[tex]\displaystyle z^3 = 216(\cos 360^\circ + i\sin 360^\circ)[/tex]
Evaluate:
[tex]\displaysyle z^3 = 216( 1 + i(0)) = 216[/tex]
In conclusion, our answer is B.
