answer/ step-by-step explanation:
hi there!
the question is asking us to solve for x for the equation
x + 3 = 5
first we need to get all the numbers on to one side of the equal sign while the other side has all the variable
in order to do that we need to subtract 3 on both sides
x + 3 = 5
- 3 - 3
and that leaves us with our answer!
x = 2

Aziz purchesis 4 2/8 feet of fabric he used 1/5 of fabric to make a tote bag how much fabric will aziz have left over?
Answer:
3/20
Step-by-step explanation:
Fabric left over = total fabric purchased - total fabric used to make a tote bag
total fabric used to make a tote bag = [tex]4\frac{2}{8}[/tex] × [tex]\frac{1}{5}[/tex] =
[tex]\frac{34}{8}[/tex] × [tex]\frac{1}{5}[/tex] = [tex]\frac{34}{40}[/tex]
fabric left over = 1 - 34/40
40 / 40 - 34/40 = 6 /40
To transform to the simplest form. divide both the numerator and the denominator by 2

Mrs Fuller plants a 4 inch tomato plant in her garden. The tomato plant grows at a rate of 2 inches each week. Which equation can be used to determine h, the height of the tomato plant in inches after w weeks?
Answer: 4 + 2w
Step-by-step explanation:
The height of the tomato plant in inches after w weeks will be the value of the current height plus the weekly growth pee week. This can be represented in an equation as:
h = 4 + 2(w)
h = 4 + 2w
For example, the height of the tomato plant in inches after 5 weeks will be:
h = 4 + 2w
h = 4 + 2(5)
h = 4 + 10
h = 14 inches
16 = 4a + 8

Which of the following is TRUE about sampling distributions?
Larger sample gives worse data. More samples give worse data.
Larger sample gives better data. More samples give worse data.
Smaller sample gives worse data. More samples give better data.
Smaller sample gives better data. More samples give better data.
Answer:
Smaller sample gives worse data. More samples give better data.
Step-by-step explanation:
A sample is the number of elements that are used in a given experiment.
For example, if you do a survey to 100 random people, then your sample is 100 people.
Here we can see something kinda obvious, if you increase your sample, then more people answer your survey, wich means that more samples give more data, and more data is better, then more sample gives better data.
We also can see that if we have a small sample (for example 10 people) the survey will not be really useful, this happens because if we have really small samples the sample may be biased, and we always want to aboid this.
Then:
Smaller samples give worse data, and as we increase the samples, we also get better data.
The correct option is:
"Smaller sample gives worse data. More samples give better data."
A .Write an equation for the trend line in slope -intercept form .
Given:
The graph of a trend line.
To find:
The equation of the trend line is slope intercept form.
Solution:
From the given graph it is clear that the equation of the trend line is passes through the points (0,25) and (5,50).
Slope of the line is:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{50-25}{5-0}[/tex]
[tex]m=\dfrac{25}{5}[/tex]
[tex]m=5[/tex]
The line passes through the point (0,25). So, the y-intercept of the line is 25.
Slope intercept form of a line is:
[tex]y=mx+b[/tex]
Where, m is slope and b is y-intercept.
The slope intercept from of the line is:
[tex]y=(5)x+(25)[/tex]
[tex]y=5x+25[/tex]
Therefore, the equation for the trend line in slope -intercept form is [tex]y=5x+25[/tex].
The surface area of a triangular prism is 18: square inches. What is the surface area of a similar solid that has been enlarged by a scale factor of 2.52?
Answer:
45.36 square inches
Step-by-step explanation:
Given the following
Surface area of a triangular prism = 18 square inches
If it is enlarged by a scale factor of 2.52, the area of the enlarged solid is expressed as;
Area of enlarged solid = area of original sold * scale factor
Area of enlarged solid = 18 * 2.52
Area of enlarged solid = 45.36 square inches
hence the surface area of a similar solid that has been enlarged by a scale factor of 2.52 is 45.36 square inches
Answer:45.36 square inches

Answer:
Step-by-step explanation:
.......
Answer:
The expression will be : (x+9) /2
What is algebraic expression?An algebraic expression is an expression built up from integer constants , variables , and the algebraic operations.
Let us take the number to be : x
Now, ( half of the sum of 9 and a number ) will be : (x+9)/2
Dividing x and 9 with 2 we get,
the second expression which is different but equivalent to first will be :

The circular stone mound in Ireland called Newgrange has a diameter of 250 feet. A passage 62 feet long leads towards the center of the mound.
Find the perpendicular distance x from the end of the passage to either side of the mound. Round your answer to the nearest tenth.
Answer:
Step-by-step explanation:
it's 125 for the radius and also 125-62 = 63
so 125+63 = 188
188 * 62 = X^2
11656 = X^2
107.96 = x
108.0 = x ( to the nearest tenth )
The perpendicular distance x from the end of the passage to either side of the mound is : 107.93 feets
Diameter = 250
To obtain the perpendicular distance, x :
We use the relation : x × x = Length to either side of mound :
Mathematically ;
x × x = 62 ft × (250 - 62)
x² = 62 × 188
x² = 11656 ft²
Take the square root of both sides ;
x = √11656
x = 107.9629 ft
Hence, the perpendicular distance x from the end of the passage to either side of the mound is : 107.93 feets

Step-by-step explanation:
A visual for law of sines can be found below
Sin (an angles) over its opposite side length is equal to sin ( a different angle) over its opposite side length
In the given triangle we are given side length BC and side length AB
we are also given AB's opposite angle (40)
And we need to find side length BC's opposite angle (A)
That being said we are given enough information to set up an equation using the law of sines
Remember angle A's opposite side length is 16 and the angle that has a measure of 40 degrees' opposite side length is 12
so the equation would look like...
[tex]\frac{sin(40)}{12} =\frac{sin(A)}{16}[/tex]

Answer:
1.) 2.5cm
2.) 1 3/4
3.) 1.6
4.) 4/5
5.) 18.84
Step-by-step explanation:
So the radius is half of the diameter, so the first one would be:
5 ÷ 2 = 2.5
We do the same thing for the next one:
3 1/2 ÷ 2 = 1 3/4
Now we have to go backwards because we have the radius and we're trying to find the diameter:
0.8 x 2 = 1.6
And the next one:
3/5 x 2 = 4/5
Now to find the circumference, we multiply the diameter by pi (3.14)
6 x 3.14 = 18.84
let me know if any of these are wrong
hope this helps:)
