under a 200:1 microscope, a microorganism appears to have a length of 0.75in, how long is the microorganism
Answer:
0.00375 inches
Step-by-step explanation:
Since the microscope makes the microorganism appear ×200 larger, that would mean we would have to divide by 200 to get the original size. 0.75/200= 0.00375.
Harrison is having a tub of yoghurt for a snack. The tub weighs 30g and holds 120ml, so he says that his snack (the tub and yoghurt together ) weighs 150g. Can you please explain why his mistake is mistaken please?
Step-by-step explanation:
Given
Tub weighs 30 g and can hold 120 ml yogurt
It is not right to simply write the ml to gm unless it is case of water
mass is given by product of volume with density
So, density of yogurt is different than water. It is not appropriate to write 120 ml to 120 gm
Thus, the claim of Harrison is wrong that his snack weighs 150 gm.

A cylinder has a height of 5 cm. What is the lateral and surface area of cylinder, if the circumference of one circle is 18.84 cm?
Answer:
Lateral Surface Area = 94.25 cm²
Surface area = 150.8 cm²
Step-by-step explanation:
A cylinder has a height of 5 cm. What is the lateral and surface area of cylinder, if the circumference of one circle is 18.84 cm?
Step 1
We have to find the radius of the cylinder
We are told in the question that:
The circumference of one circle is 18.84 cm
Circumference of a circle = 2πr
18.84cm = 2πr
r = 18.84/2π
r = 2.9984791279cm
Approximately the radius = 3cm
Step 2
We find the Lateral Surface Area of the Cylinder
The formula =2πrh
r = 3cm
h = 5cm
=2×π × 3 × 5
= 94.24778 cm²
Approximately = 94.25 cm²
Step 3
We find the Surface Area of the Cylinder
The formula =2πr(r + h)
r = 3cm
h = 5cm
=2×π × 3 × 5(3 + 5)
= 150.79645 cm²
Approximately = 150.80 cm²
GUYS PLEASE HELP!!A gardener plans to construct a triangular garden using logs for the edges. She has logs that measure
5 meters and 3 meters. Which of the following lengths could be used for the third side of the garden?
A 2 meters
B 6meters
C 8meters
D 9meters
Answer:
6 meters
Step-by-step explanation:
The sum of the lengths of any two sides of a triangle is always greater than the length of the third side. And this MUST be true for all the combinations
The only length where this is true is 6
3+5 is greater than 6
2+6 is greater than 5
5+6 is greater than 3

What is the area of a rectangle that is 1 1 4 1 4 1 1, start fraction, 1, divided by, 4, end fraction meters long and 3 4 4 3 start fraction, 3, divided by, 4, end fraction of a meter wide?
Answer:
4 11/16 m²
Step-by-step explanation:
The formula for the area of a rectangle = Length × Width
From the question:
Length = 1 1/4 m
Width = 3 3/4m
Area of the rectangle =
1 1/4 m × 3 3/4 m
= 5/4 m × 15/4 m
= 75/16 m²
= 4 11/16 m²
Area of the rectangle = 4 11/16 m²

Diego is selling raffle tickets for $1.75 per ticket.
Complete the table to show how much money he would earn if he sold each number of tickets.
Answer:
1.75(x)
Step-by-step explanation:
you can make an algebraic expression to make this simpler. if x = the number of tickets. then, you want to create the expression. it will be .... 1.75(x).
you plug whatever number you need for the table in as x. for example, if you want to see how much money diego would make for 6 tickets you write 1.75*6
What is the common ratio of the sequence?
-2, 6, -18, 54
Answer:
The common ratio of the sequence is -3
Step-by-step explanation:
The reason why the answer is -3 because every single number is multiplied by -3. If you need an explanation on how I found it, here it is:
To determine the common ratio by dividing each number in the sequence from the number preceding it. If the same number is not multiplied to each number in the series, then there is no common ratio.

I completely forgot how to do this, so if you can answer and give an explanation, I’d really appreciate it!
Answer:
C
Step-by-step explanation:
Well to do this we can eliminate answers that seem unreasonable and just calculate the ones we think might be it
We know it can't be the first one or the second since its perimeter isn't 32
It could be the third one so we can check the perimeter
3+3+16+16=38
so it is the third one
it's all on the picture
find the missing angle measure
m<s=
m<u=
Answer and Step-by-step explanation:
The interior angles of a triangle a add up to 180. We can find x by subtracting everything from 180, and then divide for x.
180 = x + 4 + 68 + x
Simplify.
180 = 2x + 72
Subtract 72 from both sides of the equation.
108 = 2x
Divide each side by 2.
x = 54
The angles of the triangle are:
Angle S = 54
Angle U = 58
Angle T = 68

Omar has a bag that contains pineapple chews, cherry chews, and peach chews. He performs an experiment. Omar randomly removes a chew from the bag, records the result, and returns the chew to the bag. Omar performs the experiment 51 times. The results are shown below:
A pineapple chew was selected 11 times.
A cherry chew was selected 28 times.
A peach chew was selected 12 times.
Based on these results, express the probability that the next chew Omar removes from the bag will be cherry chew as a fraction in simplest form.
Cherry was picked the most which was 28 times out of 51
The probability of picking cherry is 28/51

What is the slope of the line?
Answer:
1/2
Step-by-step explanation:
y = mx + b is slope intercept form.
b = y intercept. where the line first passes through on the y axis
that number is 3.
y = mx + 3.
to find M (slope) you have to do RISE / RUN.
Run is going left or right from a point
Rise is going up or down from a point.
To make sure you find the slope, when you Rise and Run, it has to hit another point on the graph.
From the y - intercept 3, RISE (go up) 1 and RUN (go left) 2.
So, the slope is 1/2.
