9 What dimensions do we need a rectangular

Mathematics
1 answer:

3 0

Answer:

W=30m L=90m

Step-by-step explanation:

A =2,700 m²

L=W+60

we know that area of a rectangle is A=L*W so we sustitute what we know

A=L*W

2,700 = (W+60)*W distribute

2,700 = W² +60W subtract 2,700 from both sides

W²+60W-2,700 =0

solve the quadratic equation with quadratic formula or on the calculator on the graph and will get W= -90 and W=30. Reject the -90 value because we can not have negative measurements. Our solution is W=30

L=A/W=2,700/30=90

write and solve a real- world problem involving the multiplication of a fraction and a whole number whose product is between 10
Tomtit [17]

Answer:

Real word Problem:- Jean is working in a pizza shop. She has 60 kg of flour. She has used one-fifth of it for making pizzas. How much flour she used for making pizzas?

Solution:- Quantity of flour she has= 60 kg

The quantity she used in making pizzas=\frac{1}{5}\ of\ 60

=\frac{1}{5}\times60=12\ kg

hence, she used 12 kg of flour for making pizzas.

Here the multiplication of a fraction and a whole number =\frac{1}{5}\times60 and its answer is between 10 and 15, since 10<12<15.

I need the answer fast
Fantom [35]

Answer:

B. What was the highest temperature this month?

Step-by-step explanation:

Rory is recording the <em>high</em><em>est</em><em> temperature</em> for the duration of the day for month's worth of data.

B. is the easiest one to answer, as you simply will have to look for the greatest number within the set, and that will be the answer.

A. is too broad, and does not imply that only the "high temperature" is needed, rather just a leveled temperature within day in that month.

C. is the opposite of what Rory had recorded, and without data, he cannot answer it.

D. is answerable as well, but, again, the only temperature recorded is the high temperature. Temperature can fluctuate depending on the time of the day, and can be in the 50s one hour and the 90s in another.
