Answer:
1200 inches
Step-by-step explanation:
Given that:
Scale used by Anna in her drawings = 1 : 600
Length of drawing made by Anna of a building = 6 inches
Scale used by Greg in the drawing = 1 : 300
To find:
The length of scale drawing made by Greg.
Solution:
Here, we first need to find the original length of the building so that we can find the length of scale drawing made by Greg.
Ratio 1 : 600 means 600 is the actual length of building, if the length of scale drawing is 1.
Here, we are given length of scale drawing as 6 inches, therefore the actual length of building = 6 [tex]\times[/tex] 600 = 3600 inches
Now, applying the ratio 1 : 300, we get the length of scale drawing by Greg as [tex]\frac{3600}{3}[/tex] = 1200 inches

The Reiter family uses three different-sized scoops to serve mashed potatoes : blobs, globs and gobs (these names are so weird aren't they). 2 blobs are equal to 1 glob, and 5 globs equal 3 gobs of mashed potatoes. A bowl holds 12 gobs of potatoes. How many blobs are there in the bowl? RATIO PROBLEM!!! DUH, DUH, DUHHHHHHH.
Answer: 30 blobs
Step-by-step explanation:
The ratios are:
2 blobs: 1 glob
5 globs: 3 gobs
If the bowl can hold 12 gobs, then we can multiply the 5:3 ratio by 4, to make solving easier. We get the ratio 15:12 and then we need to multiply the 2:1 ratio by 15 to get the answer 30 blobs

can yall do the work of the answer 95 to this
9514 1404 393
Answer:
? = 95°
Step-by-step explanation:
Long arc QR is twice the measure of inscribed angle QSR, so is 2×95° = 190°. That, together with the remaining short arcs ? and RS will make up the total circle of 360°.
arc QR + arc RS + ? = 360°
190° +75° +? = 360°
? = 360° -265° . . . . . . subtract 265° from both sides
? = 95°

the metal bar/random line is almost the same size as the other two sides of the triangle. if one side is 32ft, then the opposite side is 32ft also. the bottom is 100ft, so we could eliminate C. because it couldnt be that number. now the bottom triangle, one side is 40ft so the other side has to be 40ft as well. its asking about the metal bar.
its either:
A. 53.2ft or
B. 44.4
because the line is almost the same size as 32ft. its almost a equallateral triangle. i would go with A. though because if you imagine the line at the bottom of the line (100ft.) the line would go over half of it (and 53.2 is over half of 100) so i would say
A.53.2
if this didnt help let me know. and i will delete this (if i can-)
Explain how you know when 2 ratios are proportional.
Answer:
Ratios are proportional when they represent the same relationship.
Step-by-step explanation:
Such as: finding equivalent fractions
Answer:
Ratios are proportional if they represent the same relationship.
Step-by-step explanation
One good way to tell is to make them fractions and then reduce them. If the reduced fractions are the same, you ratio is proportional! Good luck !

Answer: Choice H (upper right corner)
====================================================
Explanation:
Refer to the diagram below.
I started with the set of five circles you were given. Then I cut each of them in half. This results in 2*5 = 10 sections (each section is numbered in blue). If you shade 9 of those 10 sections, then you'll represent the fraction 9/10. This is what choice H represents, so that's why it's the answer
9/10 = 0.90 in decimal form
0.90 = 90% in percent form
