Answer:
Just took test, got it right. In the following:
Step-by-step explanation:
Scenarios:
A- Survey
B- Observation
C- Experiment
D- Survey
#3)answer is choice D.77+W<_95;W<_18
#4)answer is choice A. t<7
STEP 1:
convert meters to centimeters
100 cm= 1 meter
= 100 cm/m * 2.5 m
= 250 cm
STEP 2:
x= length of first shelf
2x+18= length of second shelf
x-12= length of third shelf
x+4= length of fourth shelf
since the whole board has to be used, add lengths of all shelves and set it equal to the whole length of the board (250 cm).
x + (2x+18) + (x-12) + (x+4)= 250 cm
combine like terms
5x + 10= 250
subtract both sides by 10
5x= 240
divide both sides by 5
x= 48
STEP 3:
find length of second shelf
= 2x + 18
= 2(48) + 18
= 114 cm
CHECK:
x + (2x+18) + (x-12) + (x+4)= 250
48 + (2(48)+18) + (48-12) + (48+4)= 250
48 + (96+18) + 36 + 52= 250
48 + 114 + 36 + 52= 250
250= 250
ANSWER: Shelf two is 114 cm.
Hope this helps! :)
Answer: 38
Step-by-step explanation:
3.8=19/5
u have to flip the reciprocal to divide by fraction so 1/10 will be just 10
Then u get 19/5 x 10
You can reduce the GCF so it would be 19 x 2
19 x 2 = 38
Or you can plug it into your calculator (3.8 x .1)
The present value of the loan will be = R36,250
<h3>Calculation of the present value</h3>
The principal capital (P) = R25 000
Interest rate for the payment (R)= 7.5%
Time for the payment (T)= 6 years
Therefore simple interest = P×T×R/100
= 25,000×6×7.5/100
= 250×6×7.5
= R11,250
The present value of the loan will be;
= 25,000 + 11,250
= R36,250
