Answers
Answer:
x = -0.4
Step-by-step explanation:
Given:
-9x + 0.4 = 4
To move all constant to the right side of the equation, perform subtraction operation
That is, subtract 0.4 from both sides of the equation
-9x + 0.4 - 0.4 = 4 - 0.4
-9x = 4 - 0.4
-9x = 3.6
Perform division operation to isolate the variable
That is, divide both sides by -9
-9x / -9 = 3.6 / -9
x = -0.4
Answer:
1 Subtract 0.4
2 Divide by -9 on both sides
3 -0.4

Step-by-step explanation:
The drama club spent $450 on tickets and buses for a field trip to the theater. 15 members of the drama club attended the field trip. The total cost for the buses was $60. What was the cost of each theater ticket? Pick the correct equation and then solve for the cost of each theater ticket.
Answers
Answer: 525
Step-by-step explanation:
450+15+60=525
Answer:
The cost of each ticket is $30.
Step-by-step explanation:
$450 is the total cost, so to get individual ticket prices you need to divide by the total number of drama club members.
450 ÷ 15 = 30

Find the values of the ratios (red to blue) of the perimeters and areas of the similar figures. Write the ratios as fractions in simplest form.
Answers
Answer:
Please check the explanation.
Step-by-step explanation:
BLUE PENTAGON
The blue shape represents the Pentagon
The length of the side a = 7
As there are 5 sides.
Thus,
The Perimeter of the Blue Pentagon = P = 5a = 5(7) = 35
Using the formula to determine the area of the Pentagon
[tex]A=\frac{1}{4}\sqrt{5\left(5+2\sqrt{5}\right)}a^2\:\:\:\:\:\:\:\:\:\:\:\:\:[/tex]
[tex]A=\frac{1}{4}\sqrt{5\left(5+2\sqrt{5}\right)}\left(7\right)^2\:\:\:\:\:\:[/tex]
[tex]A\approx 84.3\:\:\:[/tex]
Thus,
The Area of the Blue Pentagon = [tex]A\approx 84.3\:\:\:[/tex]
RED PENTAGON
The red shape represents the Pentagon
The length of the side a = 4
As there are 5 sides.
Thus,
The Perimeter of the Red Pentagon = P = 5a = 5(4) = 20
Using the formula to determine the area of the Pentagon
[tex]A=\frac{1}{4}\sqrt{5\left(5+2\sqrt{5}\right)}a^2\:\:\:\:\:\:\:\:\:\:\:\:\:[/tex]
[tex]A=\frac{1}{4}\sqrt{5\left(5+2\sqrt{5}\right)}\left(4\right)^2\:\:\:\:\:\:[/tex]
[tex]\:A\approx 27.5[/tex]
The Area of the Red Pentagon = [tex]\:A\approx 27.5[/tex]
Conclusion:
The Perimeter of the Blue Pentagon = 35
The Perimeter of the Red Pentagon = 20
Thus, the ratio of the perimeter is: 35/20 = 7/4
The Area of the Blue Pentagon = 84.3 = 843/10
The Area of the Red Pentagon = 27.5 = 275/10
Thus, the ratio of the Area is:
[tex]\frac{\frac{843}{10}}{\frac{275}{10}}=\frac{843}{275}[/tex]
Priya and Han both factored the number 80. Priya says they should both get the same answer even if they started with different factor pairs. Han disagrees. Who is correct
Answers
Answer:
Priya is right.
Step-by-step explanation:
The factors of 80 is 1, 2, 4, 5, 8, 10, 16, 20, 40, 80
The factor pairs of 80 are
1 x 80, 2 x 40, 4 x 20, 5 x 16 and 8 x 10
If Priya picks 2 x 40, then it's prime factorisation will be, 2 x 2 x 2 x 2 x 5 = 2⁴ x 5.
If Han picks, 5 x 16 = 5 x 2 x 2 x 2 x 2 = 5 x 2⁴ = 2⁴ x 5. This is the same.
Therefore, Priya is correct, because the factors of 80 are always the same, therefore which ever you start with, you'd always get the same answer.

10 cm
Step-by-step explanation:
This is the Pythagorean triple 3, 4, 5, in which the two legs are multiples of 3 and 4, while the hypotenuse is a multiple of 5. Observing the given numbers it can be deduced that the second multiple of 5 is what is needed to complete this triple, therefor the hypotenuse must be 10 cm.

2 consecutive numbers that add up to 719
Answers
Answer:
359+360
Step-by-step explanation:
Answer:
359+360
Step-by-step explanation:
Here we will use algebra to find three consecutive integers whose sum is 719. We start by assigning X to the first integer. Since they are consecutive, it means that the 2nd number will be X + 1 and the 3rd number will be X + 2 and they should all add up to 719. Therefore, you can write the equation as follows:
(X) + (X + 1) + (X + 2) = 719

Thus, the other base angle is x too

thus;
3x + x + x = 180
5x = 180
x = 180/5

Angela works 18 hours a week for 12 weeks in the summer at the local swimming pool as a life guard. She earns $13 per hour. Her employer takes 15 percent out of her check for federal income tax withholding and 6.2 percent for Social Security and 1.45 percent for Medicare. She will receive 12 paychecks, one for each week she works. Calculate Angela’s weekly gross pay
Answers
Answer:
We know that per week, she works 18 hours.
For each of these hours, she earns $13.
Then in one week, she earns a total of:
18*$13 = $234
This is her gross pay (the pay before the taxes apply)
Now we know that her employer takes:
15% for federal income tax withholding.
6.2% for Social Security
1.45% for Medicare.
If we add all of these, we get:
15% + 6.2% + 1.45% = 22.65%
This means that 22.65% of $234, is taken by her employer to pay taxes and such.
Then the amount left is:
M = $234 - ( 22.65%/100%)*$234 = $234 - 0.2265*$234 = $180.999
And we can round the last digit to $181 (because we can not have a 0.009 of a cent)
This means that her weekly net pay is $181
And she works for 12 weeks, this means that in total, she will earn:
12*$181 = $2,172

Answers
Answer:
283.19
Step-by-step explanation:
Find the number in the hundredth place 9 and look one place to the right for the rounding digit 2 . Round up if this number is greater than or equal to 5
and round down if it is less than 5 .
Answer:
283.19
Step-by-step explanation:
So as you should already know, the 2 is the hundreds, 8 is the tenths, and 3 is the ones, but you may not know the ones after it. The number after the little dot (decimal) is a 1 and is called the tenths and the one after is the hundredths and then thousandths and so on. You want to know the hundredths so just keep all of the numbers until you get to the number that is 2 places after the decimal and look at the last number and if its below 5, keep the hundredths the same but if its 5 or over make the hundredths 1 higher. for example 3 stays the same because the next number is below 5. This is how you do rounding with decimals! Please give Brainliest if this helps!
