9 ÷ 4.5 = ?

Answers

Answer 1

Answer: 2

Step-by-step explanation:

Change the divisor 4.5 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.

We then have the equations:

90 ÷ 45 = 2

and therefore:

9 ÷ 4.5 = 2

Solve this system using substitution: y=5x and 7x-3y=32

Answers

Solve equation [2] for the variable y

[2] 2y = -5x + 1

[2] y = -5x/2 + 1/2

// Plug this in for variable y in equation [1]

[1] 7x - 3•(-5x/2+1/2) = -5

[1] 29x/2 = -7/2

[1] 29x = -7

// Solve equation [1] for the variable x

[1] 29x = - 7

[1] x = - 7/29

// By now we know this much :

x = -7/29

y = -5x/2+1/2

// Use the x value to solve for y

y = -(5/2)(-7/29)+1/2 = 32/29

Solution :

{x,y} = {-7/29,32/29}

Find the distance between​ S(2.3,4.8) and​ T(6.4,7.9).

Answers

Answer:

5.1

Step-by-step explanation:

thats what i got on savvas hope this helps!

The distance between the points​ S(2.3,4.8) and​ T(6.4,7.9) is 5.14 units.

What is distance between the points?

Distance between two points is the length of the line segment that connects the two points in a plane.

Given that, two points S(2.3,4.8) and​ T(6.4,7.9), we need to find the distance between them,

The distance between the two points =

D = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Here, (x₁, y₁) and (x₂, y₂) are S(2.3,4.8) and​ T(6.4,7.9)

So,

D = [tex]\sqrt{(6.4-2.3)^2+(7.9-4.8)^2}[/tex]

= [tex]\sqrt{(4.1)^2+(3.1)^2}[/tex]

= [tex]\sqrt{26.42[/tex]

= 5.14

Hence, the distance between the points​ S(2.3,4.8) and​ T(6.4,7.9) is 5.14 units.

The perimeter of the worksheet is 28 inches. The worksheet is 6 inches tall. How long is it?

Answers

Answer:

The anwser is that it's 8 inches

Step-by-step explanation:

How i figured this out is since it's a woksheet,

I can guess that its a rectangle or quadrtilateral. One side is 6 inches, so the exact opposite side is also the same size, so we would have to double the 6 to 12. We know that the perimeter is 28, we can subtract 28 from 12 so that we can find out how long it is. We get 16 from 28-12 and we need to half the amount to find out how long one side is. let me know if you have any more quesitons because i dont know if i explained it well

Lindsey purchased a random sample of 25 tomatoes at the farmers market. The 95% confidence interval
for the mean weight of the tomatoes is 90.6 to 112.4 grams.
What is the Point Estimate?
What is the Margin of error?

Answers

Answer:

3 & 5

Step-by-step explanation:

The value of point estimate is 101.5 and value of margin of error is 10.9 gram if the Lindsey purchased a random sample of 25 tomatoes at the farmers market.

What is the margin of error(MOE)?

It is defined as an error that provides an estimate of the percentage of errors in real statistical data.

The formula for finding the MOE:

[tex]\rm MOE = Z\times \dfrac{s}{\sqrt{n}}[/tex]

Where   Z is the z-score at the confidence interval

            s is the standard deviation

            n is the number of samples.

Let's suppose m is a point estimate and ME is the margin of error.

The structure of the confidence interval is:

(m—ME, m + ME)

The given confidence interval is (90.6, 112.4)

Then, m—ME = 90.6 ..... (1)

m + ME = 112.4 ..... (2)

After solving equation (1) and (2) we get:

m = 101.5

ME = 10.9 grams

Thus, the value of point estimate is 101.5 and value of margin of error is 10.9 gram if the Lindsey purchased a random sample of 25 tomatoes at the farmers market.

Find the surface area of the regular pyramid. 14mm and height is 11.

Answers

Answer:

504

Step-by-step explanation:

TSA (total surface area) = 1/2(p)(l) + B

p (perimeter) = 4(14) = 56

l (slant length) = 11

B (area of vase) = 14(14) = 196

TSA = 1/2 (56) (11) + 196

= 28(11) + 196

= 308 + 196

= 504
