Answer: Noah has 75 marbles. Noah has more marbles. this is because 34 times 3 is equal to 102. since michelle takes 9 marbles from EACH box, 9 times 3 is 27. 102 minus 27 is 75

A set of house plans is made in the ratio 25 : 1. If a room is 5 m long, how long is this room on the plan?

Answers

Answer:

0.2 on the plan

Step-by-step explanation:

The unit is not given, so whatever the unit is will follow. I'm going to say that it is in meters.

25 meters in real life=1 inch (just a guess) on the plan.

25÷5 (the room length given) = 5

1÷5=0.2

You divide them both by the same number so your ratio can have the same rate. Hope this helps.

Answer:

Option B is correct.

\triangle RST \cong \triangle TUR  

Step-by-step explanation:

Given: RSTU is a parallelogram.

By definition of parallelogram, two pairs of opposite sides are congruent in length.

TU \cong RS and TS \cong RU

In triangle RST and  triangle TUR

RS \cong TU  [Side]  

TS \cong RU  [Side]

RT \cong RT   [Common side]

SSS(Side-Side-Side) postulates states that if three sides of one triangle are congruent to three sides of other triangle, then the triangles are congruent.

then, by SSS postulates we have;

\triangle RST \cong \triangle TUR    


Answer:

Answer is below.

Step-by-step explanation:

Given: RSTU is a parallelogram.

Triangle RST congruent to triangle TUR.

You are planning to make a collage and are gathering materials.for the backing you will use a piece of heavy recycled cardboard that is 4 3/4 feet longhand 2 2/5 feet wide .one side of the cardboard will be covered with fabric.the other side will be left bare against the wall when you hang the collage. Estimate how much fabric you will need explain ? Part 2 you decide to place a design in the middle of the cardboard. This will take up an are of 4 1/2 squqre feet rectangular cut outs that have an area of3/8 sq feet will cover this area how many rect will fit in this area?

Answers

1. 4 3/4 feet = 19/4 feet
2 2/5 feet=12/5 feet.
multiplying them together yields 
(19)/(4) * (12)/(5) =
=  (57)/(5) = 11.4 ft^(2)

Part 2: 
11.4 ft^2 - 4 1/2 ft^2=
11.4-4.5=6.9 ft^2 = 69/10 ft^2 left after you subtract the decoration in the middle
Now you're trying to find now many rectangular cutouts (that each are 3/8 ft^2) will fit in the remaining space.
You do that by dividing the remaining space left by 3/8:
(69)/(10) / (3)/(8) =  (69)/(10) * (8)/(3) =  (92)/(5)
since you have to have a whole number of cutouts, you round 92/5 down to 90/5, which is 18 cutouts
