Natalia is drawing a rectangle. She wants the width to be at least 10 inches and the perimeter to be no more than 72 inches. A.)
Serga [27]

Answer:

A) w\geq 10 and 2l+2w\leq 72

B) w=8 l=28

C) w=11 l=39 does not work

Step-by-step explanation:

An inequality is an equation that has a solution set or many possibilities for solutions. You write it with an inequality sign like\leq , \geq , < or >.

A) The width must be at least 10 which means it must be equal o 10 or greater.

w\geq 10

The perimeter has the formula for a rectangle of 2l+2w=P. If the perimeter is no more than 72, then it is equal to 72 or less than it.

2l+2w\leq 72

B) The width could be 8 and the length could be 28 since 2*8+2*28 = 72

C) The width cannot be 11 and the length 39 cince 2*11 + 2*29 = 100.

Box 1: Dimensions: x by 3x by x3 Area of base = x(3x) = 3x2 Box 2: Dimensions: x by 4x – 1 by x3 Area of base = x(4x – 1) = 4x2
andriy [413]

Answer:

box 1: monomial

box 2: binomial

Step-by-step explanation:

reasoning: Box 1’s volume is modeled by a monomial times a monomial, so it will be a monomial.

Box 2’s volume is modeled by a monomial times a binomial, so it will be a binomial.

Explain the difference between using the tangent ratio to solve for a missing angle in a right triangle versus using the cotange
Lena [83]

Answer:

While determining the angle \theta with the tangent ratio or cotangent ratio uses the same sides lengths but the ratios are inverse of each other.

Step-by-step explanation:

See the diagram attached.

Let us assume a right triangle Δ ABC with ∠ B = 90°. Now, assume that the angle ∠ CAB = \theta and the sides AB, BC, CA are 3, 4, 5 units respectively.

The tangent ratio of an angle \theta is given by  

\tan \theta = \frac{BC}{AB} = \frac{4}{3}  

Again, the cotangent ratio of angle \theta is given by  

\cot \theta = \frac{AB}{BC} = \frac{3}{4}  

Therefore, in both the cases of tangent ratio and cotangent ratio are inverse of each other and while determining the angle \theta with the tangent ratio or cotangent ratio uses the same sides lengths but the ratios are inverse of each other. (Answer)

An item is regularly priced at $35 . It is on sale for 80% off the regular price. What is the sale price?
Alexxx [7]

First change 80% to a decimal

80% = 80/100 = 0.80

Next, multiply 35 with 0.80

35 x 0.80 = 28

Next, subtract the number gotten (28) with the regular price (35)

35 - 28 = 7

-------------------------------------------------------------------------------------------------------------------

$7 is the sales price

-------------------------------------------------------------------------------------------------------------------

hope this helps
