For each equation, choose the statement that describes its solution. if applicable, give the solution.5(y+1)-7 = 3(y-1)+2y

no solution

y = ?

all real numbers are solutions

Answers

Answer 1

Answer:

Answer:

This equation has no solution.

Step-by-step explanation:

Perform the indicated multiplication: 5(y+1)-7 = 3(y-1)+2y

We get 5y + 5 - 7 = 3y - 3 + 2y. Subtracting 5y from both sides yields -2 = -3, which is never true. This equation has no solution.

The Kahn's Family lives in a house that has a backyard in the shape of an isosceles trapezoid and a triangle. The area of the backyard can be expressed as the sum of the area of the triangle and the area of the trapezoid, which is 1/2bh+1/2(p+q)L The base and the height of the triangle are represented by b and h, respectively. The bases of the trapezoid are p and q, and the height of the trapezoid is L. 2 Rearrange the formula to find the length of base as a function of the lengths of the other sections of the backyard.

In a batch of 960 calculators, 8 were found to be defective. What is a probability that a calculator chosen at random will be defective? Write the probability as a percent. Round to the nearest tenth of a percent if necessary.

Answers

Answer:

0.8% is a probability that a calculator chosen at random will be defective

Step-by-step explanation:

Probability of any event is given by:

$P(A) = \frac{\text{Number of required outcomes}}{\text{Total number of possible outcomes}}$ where, A is any event.

As per the statement:

In a batch of 960 calculators, 8 were found to be defective.

here,

A = Defective calculator.

⇒Number of defective calculator = 8

and

Total number of outcomes = 960 calculators.

then by definition we have;

$P(A) = (8)/(960)$

Simplify:

$P(A) \approx 0.00833333333$ = 0.833333333 %

Therefore, a probability that a calculator chosen at random will be defective to the nearest tenth place is, 0.8 %

out of 960 calculators, 8 were found be to defective

Probability:
$(8)/(960)$

A florist sells two dozen roses for $50.88. At this rate what's the cost per rose? A. $25.44 B. $0.12 C. $2.12 D. $21.20

Answers

1 dozen = 12
2 dozen = 24

24 roses for $50.88

$(50.88)/(24)$ = $2.12

1 rose = $2.12

Answer is: C. $2.12

C.2.12 two dozen is 24 cause a dozen is 12 so add 2.12 24 times or multiply then you will get $50.88

Simplify square root of 3 times square root of 21

Answers

Step-by-step explanation: To multiply the square root of 3 times the square root of 21, we simply multiply the numbers that are inside the square roots together.

So, root 21 × root 3 equals root 63.

Next, we simplify the square root of 63. 63 factors as 3 x 21 and 21 factors as 3 x 7. So we have a pair of 3's which means a 3 can come out of the radical and the 7 doesn't pair up stays in the radical so our final answer is $\sqrt[3]{7}$ .
