the perimeter of a school crossing sign is 102 inches what is the length of each side

Answers

Add up all sides lengths:

s+6 + s+6 + s + s + 2s = 102

solve for s:

6s + 12 = 102
6s = 90
s= 15

The lengths of sides are as follows:

15, 21, 21, 15, 30 inches

I hope that helps!

Answer:

The length of each side is 21 inches, 21 inches, 15 inches, 30 inches and 15 inches.

Step-by-step explanation:

Consider the provided figure.

It is given that the perimeter of a school crossing sign is 102 inches.

The figure have 5 sides having the length s+6, s+6, s, 2s and s.

Now the perimeter is the sum of all sides,

s+6+s+6+s+2s+s=102

6s+12=102

6s=102-12

6s=90

s=15 inches

The length of each side is:

s+6=15+6=21 inches

s=15 inches

2s=2×15=30 inches

s=15 inches

Hence, the length of each side is 21 inches, 21 inches, 15 inches, 30 inches and 15 inches.

Draw or write to show that the number 18 is an even number

Answers

If you divide it in half, and the two halves are whole numbers, then you know it is an even number.

Final answer:

The number 18 is considered an even number because it can be divided by 2 to result in another integer. This is confirmed by writing 18 as 2 times 9, which results in an even product.

Explanation:

In mathematics, an even number is any integer that can be exactly divided by 2 without leaving a remainder. For example, the numbers 2, 4, 6, 8, and 10 are even because each can be divided by 2 to result in another integer. If you divide an even number by 2, the result is always a whole number, and that's not the case with odd numbers. Let us examine the number 18.

If we write 18 as 2 times 9, we see that it has been turned into a product of 2 and another integer (9, in this case). This indicates that 18 is indeed an even number. Therefore, we can be sure of the fact that the number 18 is an even number, because it can be divided by 2 without leaving a remainder.

Should the quotient of an integer divided by a nonzero integer always be a rational number? Why or Why not?

Answers

Yes, it will always be a rational number. I'll expound on this by defining what a rational number is. It is any number that can be expressed as a fraction. Otherwise, it is called an irrational number with a non-terminating decimal expansion. So, although 1/3 has a non-terminating decimal expansion because it is equal to 0.33333333...., it is still a rational number because it can be expressed into a fraction.

Noel Devine bought a new dishwasher for $320. He paid 20 down and made 10 monthly payments of $34 what actual yearly interest rate did Noel pay?

Answers

IN finding the interest we need to use the following formula:
Interest= Principal x Rate x Time or I= PRT
Substitute values: I= [$20 + ($10 x $34)] -320 =$40
P= $320
R=?
T=10 months/year
I=PRT
Since R is a missing term, we will solve for R using this formula: R=I/PT
R= [$20 + ($10 x $34)-320] / ($320 x 10 months)
T=10 months÷12 months=0.83
R= ($40)/ $320 X 0.83
R= 40/ 265.6
R=15.06024096

First we need to find the amount financed, total payments and total interest

Amount financed
320-20=300

Total payments
34×10=340

Total interest=total payments-amount financed
Total interest=340-300=40

Now to find the yearly interest rate use the formula of
I=(2yc)÷(m×(n+1))
I ?
Y number of months in a year 12
C total interest 40
M amount financed 300
N number of payments 10
I=(2×12×40)÷(300×(10+1))
I=0.2909×100=29.09%

If you draw out the two components in a head-to-nose fashion, you will create a right angle triangle something like the picture, that is if I interpreted the information right (the way I interpreted it is 15m east and 8m north);
The dotted line represents the x-axis;
Θ represents the desired angle;
Using trigonometry, we can create and solve an equation to get the angle (Θ);
In this case, you can use use sin or cos, I'll go with sin:
SinΘ = opp/hyp
SinΘ = 8/15
Θ = Sin⁻¹(8/15)
= 32.23.... ⇒ 32.2°

Answer:28.071

vector component is (15,8)

i.e. its x component is 15 from origin and y component is 8 m

In the number 555.55 each digit is a 5 but the value of each 5 is different based on its place in the number. How does the value of the 5 in the tenths place compare to the value of the underlined digit 5

Answers

Final answer:

The value of each 5 in the number 555.55 depends on its place value. A 5 in the tenths place (representing 1/10 or 0.1) would have a much smaller value compared to a 5 in the hundreds place in the same number, due to the multiplying factor of ten for each place value.

Explanation:

In the number 555.55, each digit is indeed a 5. However, the value of each 5 changes depending on its place value. The tenths place, to the right of the decimal point, represents tenths or 1/10 (0.1).

If the underlined digit 5 is in the hundreds place, for example, it will have a value of 500. To compare, the value of the 5 in the tenths place (which is 0.5) is much smaller than the value of the 5 in the hundreds place. In fact, it's 1,000 times smaller because each move to the left in place value multiplies the digit by 10.

Write the equation of the sphere in standard form. 2x2 + 2y2 + 2z2 = 12x − 24z + 1

Answers

The standard equation of a sphere with center C(a, b, c) and radius r is:

[tex](x-a)^2 + (x-b)^2 + (x-c)^2 = r^2[/tex]
Now, the given equation is :

[tex]2x^2 + 2y^2 + 2z^2 = 12x - 24z + 1 \\ 2x^2 + 2y^2 + 2z^2 - 12x + 24z - 1 = 0 \\[/tex]

combine the x, y and z terms and complete the square for each variable
[tex](2x^2 - 12x) + 2y^2 + (2z^2 + 16z) = 1 \\ (x^2 - 6x) + y^2 + (z^2 + 8z) = 1/2 [/tex]

complete square for x by adding 9 to both sides

we do not complete square for y because there is not a translation on that axis

complete square for z by add 16 to both sides
[tex] (x^2 - 6x + 9) + y^2 + (z^2 - 8x + 16) = 1/2 + 9 + 16 \\ (x - 3)^2 + y^2 + (z - 4)^2 = 25 1/2[/tex]

The standard equation of a sphere with center C(a, b, c) and radius r is:

Joelle is working on a school report in a word processor. She wants to place a figure which is 13.09 cm wide so that it appears centered on the page. The width of the page is 21.59 cm.

How much margin should she leave on the left so that the figure is centered?

Do I divide the width by 13.09 to get the answer? Not very sure

Answers

Alright, so for it to be centered, it needs to be x cm away from the left side and therefore x away from the right side (due to that if it's centered, it needs to be the same distance away from both), making the total width x+13.09+x=21.59=13.09+2x. Subtracting 13.09 from both sides, we get 8.5=2x and by dividing both sides by 2 we get x=3.25

Answer:

The answer is 4.25 cm.

Step-by-step explanation:

Given is - Joelle wants to place a figure which is 13.09 cm wide so that it appears centered on the page. The width of the page is 21.59 cm.

To solve, this first we will 13.09 from the 21.59, and then divide that number in half to find the left and right margin.

The critical level for the number of bacteria spread is 1000. Starting from 500, if the bacteria count rises by 5 every second, then determine whether after 30 seconds the critical level is passed or not?

Initial count = 500

Count increasing per second = 5

Critical level = 1000

Assume that the bacteria count after t seconds is y. Then -

y = 500 + 5t

for t = 30 ↔ y = 150 + 500 = 650 < 1000 → Critical level not passed.

According to question, we have -

Cost for first three hours = $80

Cost for additional hour = $19.75

Total Budget = $200

Assume that the tank can be bought for 'n' hours. Then -

80 + 19.75n ≤ 200

Solving the inequality -

19.75n + 80 - 80 ≤ 200 - 80
