Toothpicks are used to make a grid that is 60 toothpicks long and 32 toothpicks wide. How man toothpicks are used altogether?

Answers

Answer 1

Answer: Finding how many toothpicks were used altogether is the same process as finding the area, so we have to multiply 32 by 60 which equals 1920. So the final answer is 1920

Answer 2

Answer:

Final answer:

To find the total number of toothpicks used in the grid, calculate the perimeter of the grid by adding the lengths of all its sides. In this case, the perimeter is 184 toothpicks.

Explanation:

To find the total number of toothpicks used in the grid, we need to calculate the perimeter of the grid. The perimeter of a rectangle is found by adding the lengths of all its sides. In this case, we have a grid that is 60 toothpicks long and 32 toothpicks wide. So, the perimeter is (60 + 32 + 60 + 32) = 184. Therefore, a total of 184 toothpicks are used altogether.

Laurie was scuba diving. Each time she dove 5 feet deeper, she would stop and clear her ears. After Laurie had checked her instruments 3 times, she was at her maximum depth of 60 feet. Which expression best represents Laurie's maximum depth? (4) (negative 5) (3) (Negative 4) (Negative 5) (Negative 3) (Negative 5) (20) (3) (Negative 5) (Negative 20) (Negative 3)

Answers

Complete question :

Answer:

(-5) * (20) * (3)

Step-by-step explanation:

Diving 5 feets deeper = descent = negative 5 Feets

Each time instrument is checked = (60/3) = depth of 20 feets

Number of times instrument is checked = 3

Hence, maximum depth :

Diving 5 feets deeper * Each time instrument is checked = depth of 20 feets * Number of times instrument is checked

(-5) * (20) * (3) = - 60

Assume that the mean hourly cost to operate a commercial airplane follows the normal distribution with a mean of $2,175 per hour and a standard deviation of $245.What is the operating cost for the lowest 4 percent of the airplanes? (Round z value to 2 decimal places. Omit the "$" sign in your response.)

Answers

I assume you can use either a graphing calculator with built-in normal distribution or a normal distribution chart? Either way, check z-value for p<0.04 and get z=-1.75
x=mean+(s.d.)*z=2175-1.75*245=1746.25

Suppose ∠A and ∠B are complementary angles, m∠A = (3x + 5)°, andm∠B = (2x – 15)°. Solve for x and then find m∠A and m∠B.

Answers

m∠A + m∠B = 90
(3x + 5) + (2x - 15) = 90
(3x + 2x) + (5 - 15) = 90
5x - 10 = 90
+ 10 + 10
5x = 100
5 5
x = 20

m∠A = 3x + 5
m∠A = 3(20) + 5
m∠A = 60 + 5
m∠A = 65

m∠B = 2x - 15
m∠B = 2(20) - 15
m∠B = 40 - 15
m∠B = 25

m∠A + m∠B = 90

$(3x + 5) + (2x - 15) = 90$

$(3x + 2x) + (5 - 15) = 90$

$5x - 10 = 90$

$5x - 10 +10 = 90+10$

$5x = 100$

$5x/5 = 100/5$ $Divide \ both \ sides \ by \ 5$

$x = 20$    $Solutions$

m∠A = $3x + 5$    $(x=20)$

m∠A = $3(20) + 5$ $Substitute \ x \ for \ 20$

m∠A = $60 + 5$    $Simplify$

m∠A = $65$

m∠B = $2x - 15$

m∠B = $2(20) - 15$

m∠B = $40 - 15$

m∠B = $25$
