Answer: 16 questions

Step-by-step explanation:

To find how many problems the student correctly answered on the test, we can turn 80% into a fraction.

\frac{80}{100} =\frac{16}{20}

The student answered 16 questions correctly.

The value of (0.3)^4 is 0.0081.

Unless you mean 0.3*4, then it is 1.2.

Pls answer me this all question​
Scorpion4ik [409]

Answer:

a. 5 \frac{21}{40}

b. \frac{1}{42}

Step-by-step explanation:

a. \: 12 \frac{2}{5}  - 6 \frac{7}{8}

\frac{62}{5}  -  \frac{55}{8}

\frac{62}{8}  \times   \frac{8}{8}  -   \frac{55}{8}   \times  \frac{5}{5}

\frac{62 \times 8 - 55 \times 5}{40}

\frac{221}{40}

5 \frac{21}{40}

b. \:  \frac{3}{14}  -  \frac{4}{21}

\frac{3}{14}  \times  \frac{3}{3}  -  \frac{4}{21}  \times  \frac{2}{2}

\frac{3 \times 3}{42}  -  \frac{4 \times 2}{42}

\frac{1}{42}

Hope it is helpful....

IRINA_888 [86]

Answer:

Price divided by ounces gives you the unit price. Since this is an unreal number when talking about price it will be $0.24 per ounce.

I don't get this I need help
chubhunter [2.5K]
If the PQRS in the picture is a parallelogram, that mean R + Q =180 because it was adjacent angles. Then you will get an equation like this:

R + Q =180 
(6x-10) + (x+15)= 180
7x +5= 180
7x= 175
x= 25

The angle of P would be same as R and angle of S would be same as Q. Then the answer should be:
R= P = (6x-10)= 6*25 -10= 140
S= Q = (x+15) 25+15= 40

IrinaK [193]
Hey there...
Critical path analysis is a technique that identifies the activities necessary to complete a task, including identifying the time necessary to complete each activity and the relationships between the activities.
I couldn't get an example for it but here are the steps:
1. Divide the project into tasks
2. Estimate tasks
3. Create the network diagram
4. Draw initial Gantt (bar) chart
5. Perform resource levelling
6. Compress the schedule (if necessary).


Hope it helps...
