Answer:

15

Step-by-step explanation:

Keep, Change, Flip. That is the mantra you should have when you come to division problems with fractions. So you would keep the 5, change the sign into multiplication, and flip the fraction from 1/3 to 3/1 (which actually is just 3). Then you would multiply 5 * 3. Your answer should be 15.

Answer:

15

Step-by-step explanation:

To divide any number by a fraction, flip the fraction and then multiply:

[tex]5 \div \frac{1}{3} = 5 \cdot \frac{3}{1} = 15[/tex]

Fraction does not make sense this question

Answer:

[tex]$64, \ (x+8)^2$[/tex]

Step-by-step explanation:

A perfect square trinomial is defined as an expression that is obtained from squaring a binomial equation. The perfect square trinomial is in the form of [tex]$ax^2+bx+c$[/tex].

The given expression is :

[tex]$x^2+16x$[/tex]

The co-efficient of the x-term in [tex]$x^2+16x$[/tex] is '16'.

So half of the term 16 ,

[tex]$\frac{16}{2} = 8$[/tex]

and [tex]$(8)^2=64$[/tex]

Now add 64 to the expression:

[tex]$x^2+16x+64$[/tex]

Therefore, the perfect square trinomial is

[tex]$(x+8)^2=x^2+16x+64$[/tex]

Answer:

3x*59x=

Step-by-step explanation:

Answer:

126 degrees

Step-by-step explanation:

The opposite angles of a parallelogram are equal, so 4x + 2 = 8x - 50. By subtracting 4x from both sides of this equation, we get that 2 = 4x - 50. Adding 50 to both sides yields 52 = 4x, and dividing by 4 gives us that x = 13.

By substituting this, we see that the measure of angle A is 4(13)+2, which is 54 degrees. Angle B is supplementary to angle A, so its measure is 180-54, which is 126 degrees.

lim x ---> 2^+ f(x) = 2

Answer: 36.25°

Step-by-step explanation:

Use SOHCAHTOA (sin, cosine and tangent)

SOHCAHTOA:

SOH: Sin(θ) = Opposite / Hypotenuse

CAH: Cos(θ) = Adjacent / Hypotenuse

TOA: Tan(θ) = Opposite / Adjacent

When you have an angle that you want to solve, look at what information you're given. In this problem, we're give nthe sides that are opposite to and adjacent to the angle we want to solve. So, we use TAN.

And just as a note, θ this symbol is called theta, and it represents an angle.

TAN(θ) = Opposite / Adjacent = 11/15

Then, use the inverse of tan (you can find the button on a calculator). You can use the inverse of sine, cosine or tangent whenever you want to switch them from one side of the equation to the other.

TAN(θ) = [tex]\frac{11}{15}[/tex]

θ = [tex]tan^-1(\frac{11}{15} )[/tex]

Then, using a calculator, solve. The answer is about 36.25°

Answer:

Because a 2 or a 4 was rolled 3 out of 12 times in the experiment, t so the fraction would be 3/12 (or 3 over 12).

Simplified: 1/4 (or 1 over 4)

Answer:

100 cm

Step-by-step explanation:

This is a linear function with an equation of y = 20x.

Plug 5 in for x to get 100 as your answer.

Answer: 100 cm

Step-by-step explanation: Since the car can travel 20 cm per second and it traveled 80 cm in 4 sec, then it can travel 100 cm in 5 seconds

(Tip: If it asks to show your work, try drawing a ratio table and write the centimeters it travels per second .)

Answer:

y=-3

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-3-(-3))/(3-(-4))

m=(-3+3)/(3+4)

m=0/7

m=0

y-y1=m(x-x1)

y-(-3)=0(x-(-4))

y+3=0(x+4)

y+3=0

y=0-3

y=-3

Step-by-step explanation:

Omg ilysm and thank you for spreading such positivity Muaahhh<3

Step-by-step explanation:

To find - Enter five expressions: a sum, a difference, a product, a quotient, and one that involves at least two operations that have the value of -3/4 (the fraction)

Solution -

Expression for sum is -

1/4 + (-1) = -3/4

Expression for difference is -

(1/4 - 1) = -3/4

Expression for product is -

(-3/2)(1/2) = -3/4

Expression for quotient is -

(1 - 4)/4 = -3/4

Expression that involves at least two operations is -

-(1/4 + 2/4) = -3/4

Answer:

[tex]\boxed {\boxed {\sf z= -0.1}}[/tex]

Step-by-step explanation:

A z-score helps describe the relationship between a value and the mean of a group of values. Basically, it tells us how many standard deviations away from the mean a value is. The formula is:

[tex]z= \frac{x- \mu}{\sigma}[/tex]

where x is the value, μ is the mean, and σ is the standard deviation.

For this standardized exam, the mean is 350 and the standard deviation is 40. We want to find the z-score for a value of 346.

Substitute the values into the formula.

[tex]z= \frac{ 346-350}{40}[/tex]

Solve the numerator.

[tex]z- \frac{ -4}{40}[/tex]

Divide.

[tex]z= -0.1[/tex]

The z score is -0.1, so the person with a score of 346 on the exam was 0.1 standard deviations lower than the mean.

Answer:

The mean of A and C is equal to 10.

Step-by-step explanation:

We know that,

[tex]\text{Mean}=\dfrac{\text{Sum of observations}}{\text{Total no of obervations}}[/tex]

The mean of A and B is 20,

[tex]A+B=20\\\\A+B=40\ \ .........(1)[/tex]

The mean of B and C is 24,

[tex]B+C=24\times 2\\\\B+C=48\ \ .........(2)[/tex]

The mean of A,B and C is 18,

[tex]A+B+C=18\times 3\\\\A+B+C=54\ .....(3)[/tex]

Put the value of A+B from (1) in (3),

C = 14

Put the value of B+C from (2) in (3)

A = 6

Mean of A and C is :

[tex]M=\dfrac{A+C}{2}\\\\M=\dfrac{14+6}{2}\\\\M=10[/tex]

So, the mean of A and C is equal to 10.
