what is the sum of the following equation?
3/10 + 39/100=
Answer:
69/100
Step-by-step explanation:
You need to make the denominators equal, so multiply 10 by 10, which makes 100. Whatever you do to the denominator, do to the numerator.
30/100 + 39/100 = 69/100
Answer:
69/100
Step-by-step explanation:
3/10 + 39/100
In order to find the sum of this equation, you must first identify the least common denominator.
10: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120
100: 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200
The lowest number 10 and 100 have in common is 100.
Second, we must make both fractions have a denominator of 100.
**MULTIPLY THE NUMERATOR AND DENOMINATOR BY THE SAME THINGS!!**
3/10 x 10/10 = 30/100
39/100 x 1/1 = 39/100
Lastly, we add the new fractions.
30/100 + 39/100 = 69/100
69/100 is already in the simplest form.
Therefore, 3/10 + 39/100 = 69/100
Find the length of the unknown leg of the right triangle.
Answer:
Step-by-step explanation:
a² + b² = c²
side1² + side2² = hypotenuse² side 1 = 6.75 hypotenuse = 11.25
solve for side 2 = ???
side2² = hypotenuse² - side1²
side2 = [tex]\sqrt{hypotenuse^2 - side1^2}[/tex]
= √(11.25² - 6.75²)
= √(126.56 - 45.56)
= √(81)
side 2 = 9

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

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?
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.

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

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

'Performance Task: Circle Constructions'
I need to finish this class PLEEEEAAAAASSSSSSE QmQ
Answer:
[tex] \huge \color{purple}{answer}[/tex]
To draw a circle whose radius is given, we require a ruler and compasses. Given that the radius is 5 cm, the steps to be followed are:
Step 1: Place the pointer of the compass at the initial point of the ruler (0 cm) and extend the other end of the pencil measuring 5 cm from the initial point (i.e. 5 cm)
Step 2: Mark a point O on a piece of paper. This point is supposed to be the center of the circle that you are about to construct.
Step 3: Place the pointer of the compass at point 0.
Step 4: Turn the compass slowly through 360 degrees to draw a circle.
[tex] \small\color{pink}{point \: to \: remember}[/tex]Make sure that you hold the point of the compass stiffly on the paper. You are also required to move the compass through the 360 degrees in one go for accuracy and neatness.
A circle is a locus of all points in 2 dimensional space which are equidistant from some fixed point. The constructed circle with radius 5 units is constructed below.
How to construct a circle with specific radius?We need two tools. first is ruler, and second is compass.
Take some fixed point on a paper. Let it be called OTake the ruler and draw an 'r' unit sized line segment OA.Use the compass, place its pointy tip on the fixed point O and the pen or pencil of compass on the second endpoint A of the constructed line segment.Now make a full rotation of the compass so that a ring like figure is created.This is the needed circle.
