Answer:
500
Step-By-Step Explanation:
200/50 = 4
4 * 17 = 68
68 / 2 = 34
34 x 5 = 170
170 / 17 = 10
10 x 50 = 500
What’s greater 7.8 mL or 0.78 L
Answer:
7.8 mL
Step-by-step explanation:
Answer:
.78 L
Step-by-step explanation:
Well, simple conversions
a milliliter is .0001 of a liter and 1 liter is 1000 mL, so we can safely say that .78 L is 780 mL, dwarfing the given 7.8 mL
which of the following is a graph of a line with the equation 3y-4x=-3
6th grade math I mark as brainliest
Answer: 21 units
Step-by-step explanation: Since the y-coordinates are the same, you need to find only the difference in the x-values.
Since one is positive and one is negative, (on different sides of the y-axis) you add the distances of each coordinate from there.
Or, remember that finding the difference between two numbers is a subtraction equation, and subtracting a negative is the same as adding a positive.
15 -(-6) = x
15 + 6 = x
21 = x

LMNP is a rectangle. Find the value of x and the length of each diagonal.
LN= 4x + 3 and MP = 8x -9
X=
Solution:
We know that:
Given diagonals: LN and MPLN and MP must be equal because they are diagonals of LMNP.LN = 4x + 3MP = 8x - 9Since LN and MP must be equation, equation formed: 4x + 3 = 8x - 9
Let's simplify the equation to find x.
Subtracting 4x both sides.
[tex]4x + 3 = 8x - 9[/tex]=> [tex]4x - 4x + 3 = 8x - 9 - 4x[/tex]=> [tex]3 = 4x - 9[/tex]Add 9 both sides.
=> [tex]3 = 4x - 9[/tex]=> [tex]3 + 9 = 4x - 9 + 9[/tex]=> [tex]12 = 4x[/tex]Divide 4 both sides.
=> [tex]12 = 4x[/tex]=> [tex]\frac{12}{4} = \frac{4x}{4}[/tex]=> [tex]x = 3[/tex]Now, let's find the length of each diagonal.
[tex]LN = 4x + 3 = 4(3) + 3 = 12 + 3 = 15 \space\ units[/tex][tex]MP = 8x - 9 = 8(3) - 9 = 24 - 9 = 15 \space\ units[/tex]Diagonals are equal
[tex]\\ \rm\Rrightarrow 4x+3=8x-9[/tex]
[tex]\\ \rm\Rrightarrow -4x=-12[/tex]
[tex]\\ \rm\Rrightarrow x=-12/-4[/tex]
[tex]\\ \rm\Rrightarrow x=3[/tex]

X+17>36 how would I solve this
Answer:
x > 19
Step-by-step explanation:
Hey there!
To solve this equation, you would solve it like any other equation.
Imagine that the inequality sign isn't there, and it's replaced with an equal sign. (I'm still going to use >, I just want you to pretend)
Solve:
x + 17 > 36Subtract 17 from both sides
x > 36 - 17x > 19That's it! there's your solution!
Remember this rule:

Evaluate the expression. Write your answer in scientific notation.
(1.9 x 10^9) - 6,300,000 × (5.6 x 10^2)
Please solve this expression as a scientific notation when you answer and remember.
Answer:
- 1.628 x 10^9
Step-by-step explanation:
(1.9 x 10^9) - 6,300,000 × (5.6 x 10^2) = - 1628000000
- 1628000000 = - 1.628 x 10^9
A researcher is 95% confident that the interval from 5.2 hours to 7.8 hours captures u = the true mean amount of time
it takes to fully charge a battery pack.
Is it plausible that the true mean number of hours to charge all battery packs of this type may be 5?
O No, this is not a plausible value for the population mean, because 5 is within the 95% confidence interval.
No, this is not a plausible value for the population mean, because 5 is not within the 95% confidence interval.
O Yes, this is a plausible value for the population mean, because 5 is within the 95% confidence interval.
Yes, this is a plausible value for the population mean, because the lower bound of the confidence interval, 5.2, is
greater than 5.
No, this is not a plausible value for the population mean, because 5 is not within the 95% confidence interval.
====================================================
Explanation:
The greek letter mu is the population mean. It has the symbol [tex]\mu[/tex] which looks like the letter 'u' but with a tail at the front or left side.
The question is asking if mu = 5 is plausible if the researcher found the 95% confidence interval to be 5.2 < mu < 7.8
We see that 5 is not in that interval. It's a bit to the left of 5.2
Since mu = 5 is not in the interval, it's not a plausible value for the population mean.
Have we ruled it out with 100% confidence? No. Such a thing is not possible. There's always room for (slight) error. The researcher would need to do a census to be fully confident; however, such practices are very time consuming and expensive. This is the main reason why statistics is important to try to estimate the population with a sample.

- 2p + 8 = 6 - (7p + 7)
Answer:
p=1
Step-by-step explanation:
first you need to get rid of the parenthesis
-2p+8=6-7p+7
then combine everything you can on their respective sides
-2p+8=13-7p
then get the variable on one side and for this, it can be done 2 different ways but both ways get the same answer
-2p+8=13-7p
+7p +7p
5p+8=13
or
-2p+8=13-7p
+2p +2p
8=13-5p
then, depending on which way you decide to solve it, you would then solve for x like you would in any regualar equation
first way shown above:
5p+8=13
-8 -8
5p=5
divide them both by 5 and p=1
or the other way shown above
8=13-5p
-13 -13
-5=-5p
divide both sides by -5 and then p=1
the talent show committee sold a total of 530 tickets in advance. Student tickets cost $3 each and the adult tickets cost $4 each. If the total receipts were $1740, how many of each type of ticket were sold?
Answer:
Students = 380
Adults = 150
Step-by-step explanation:
3x + 4y = 1740
and a total tickets equation of: x + y = 530
Write an exponential function in the form y=ab^x that goes through points (0,10) and (9, 5120).
The form [tex]y=ab^x[/tex] has two unknowns, namely [tex]a[/tex] and [tex]b[/tex], so you would need to have two points to find the equation (which you do). Once you have your two points, you can create a system of equations by plugging in the x and y coordinates like below:
[tex]\left \{ {{10=ab^0} \atop {5120=ab^9}} \right.[/tex]
One thing you may remember is that ANY number to the power of 0 equals 1. Knowing that, we can replace [tex]b^0[/tex] in the first equation with 1. Since 1 multiplied by any number is just that same number, that leaves [tex]a[/tex] alone in the first equation.
[tex]\left \{ {{10=a} \atop {5120=ab^9}} \right.[/tex]
The first equation now tells us that [tex]a[/tex] is 10, so we can plug 10 in for [tex]a[/tex] in the other equation.
[tex]5120=10b^9[/tex]
Now we can divide both sides by 10 to isolate [tex]b^9[/tex].
[tex]512=b^9[/tex]
To get [tex]b[/tex] alone, we have to take the 9th root of both sides.
[tex]\sqrt[9]{512} =\sqrt[9]{b^9}[/tex]
That gives us:
[tex]2=b[/tex]
We can now plug [tex]a[/tex] and [tex]b[/tex] into the form they gave us to get:
[tex]y=10*2^x[/tex]

45 + n = 325
45n = 325
$280
$7.22
Answer:
45 + n = 325
n = $280
Step-by-step explanation:
total cost = monthly cost plus the cost of lessons
total cost = $325
monthly cost = $45
number of lessons = 'n'
45 + n = 325
n = 280
