a rectangle has an area of 651m². One of the sides is 7m in length. Work out the perimeter of the rectangle​

Answers

Answer:

200

Step-by-step explanation:

So first off, let's find the other side.

651 divided by 7 = 93

93 would be the other side measurement. There are two sides that measure 93 degrees, two sides that measure 7 degrees.

93 + 93 + 7 +7 = perimeter

what is the value of x for the equation: x/3+x=x/6-1

Answers

(x/3) + x = (x/6) - 1
6x/3x = 2x
2x + x = 3x
3x = -1
x = -1/3

Answer:

I think the answer may be

X=2

Step-by-step explanation:

x÷3+x=x÷6-1

Add the common factors together to get

2x÷3=x÷6-1

subtract on the right side to get

2x÷3=x÷5

subtract 3 from both sides to get

2x=x÷2

subtract x from both sides to get

1x=2

theatrical shows. Write an expression for the number of shows they

attended per year if they accumulated the record over "Y" years. *

Answers

Answer:

6136 / Y

Step-by-step explanation:

Total number of theatrical shows = 6136 shows

Total shows was attended over a period of Y years

Hence, number of shows attended per year:

(Total Number of shows / period of years between which shows was attended)

= 6136 / Y

Nick is given $50 on a vacation. He decides to spend $5 a day. Write an equation relating to the amount of money Nick has left, y, and the number of days, x, Nick spends money

Answers

Answer:

y = -5x + 50

Step-by-step explanation:

We'll write the equation in y = mx + b form, where b is the original amount of money (50), and m is the amount of money he spends he each day(5). Since he's spending 5 dollars, that means that 5 dollars is being lost everyday, so m will be -5:

y = -5x + 50

Other Questions
Suppose that Italy and Austria both produce fish and shoes. Italy's opportunity cost of producing a pair of shoes is 5 pounds of fish while Austria's opportunity cost of producing a pair of shoes is 10 pounds of fish. By comparing the opportunity cost of producing shoes in the two countries, you can tell thatItaly has a comparative advantage in the production of shoes andAustria has a comparative advantage in the production of fish. Suppose that Italy and Austria consider trading shoes and fish with each other. Italy can gain from specialization and trade as long as it receives more than5 pounds of fish for each pair of shoes it exports to Austria. Similarly, Austria can gain from trade as long as it receives more than1/10 pair of shoes for each pound of fish it exports to Italy. Based on your answer to the last question, which of the following prices of trade (that is, price of shoes in terms of fish) would allow both Austria and Italy to gain from trade?a. 9 pounds of fish per pound of cheese.b. 18 pounds of fish per pound of cheese.c. 3 pounds of fish per pound of cheese.d. 1 pound of fish per pound of cheese.

Educators in Michigan have been trying to raising math achievement scores for several years without success. Results from the state assessment test given in fourth grade show that 52% of all fourth graders cannot subtract when borrowing from zero (regrouping with zero in the subtrahend). Two new techniques for teaching this concept have been developed by teachers who belong to the Michigan Council of Teachers of Mathematics. It is decided that each technique be used in randomly selected classrooms throughout the state. Sixty third-grade classrooms are selected to try each of the techniques. Results from the state assessment test will then be monitored for each of the next two years to see whether either of the two techniques will be effective in teaching subtraction from zero. Sixty-three percent of the students who were taught with first technique passed the objective. Only 32% of students who were taught with the second technique passed the objective.1. The population is:______.A. All fourth graders in Michigan.B. All third graders in Michigan.C. The students who were in the 60 third-grade classrooms that used each technique.D.
