plug in the answers to see which has an equal scale factor between mp and mt, and po and tr

if tr = 6, then the scale factor between po and tr is 1.5

that means, that in order to equal 9 mt would have to be 3

if mt = 3, then the scale factor between mp and mt would also be 1.5

therefore, since they both have an equal scale factor, the answer is

4) TR = 6

hope this helps!!

1. during first 10 seconds

Deffense [45]

Answer:

1. y=mx+b

(5 , 5) (10 , 10)

5m+b=5 10m+b=10

10m+b-5m-b=5

5m=5

m=1

5+b=5

b=0

So for 1---10s the slope is: y = x

2. y=mx+b

(10 , 10) (35 , 10)

10m+b=10 35m+b=10

35m+b-10m-b=0

25m=0

m=0

b=10

So for 10-----35s the slope is: y=10

3. y=mx+b

(35 , 10) (0 , 0)

35m+b=10 b=0

35m=10

m=2/7

So for 35----40s the slope is: y= 2/7 x

Simone has 20 bills. One fifth of the bills are hundreds, 1/4 of them are fifties, 1/10 of them are $20s. The rest of the bills

larisa [96]

If Simone has 20 bills, then:

1/5 of 20 = 4 [hundreds]
1/4 of 20 = 5 [fifites]
1/10 of 20 = 2 [$20s]

4 * 100 + 5 * 50 + 2 * 20 = 400 + 250 + 40 = 690 [out of $780]
4 + 5 + 2 = 11 [out of 20 bills]

So now we can easily find out she had 9 bills of tens - because 20 - 11 = 9 or because (780 - 690) ÷ 10 = 90 ÷ 10 = 9.

pickupchik [31]

You have a total of 5x6 which is 30 and you take 6 out of that 30 which leaves you with 24 brownies for 8 people. You divide 24/8 and gives you 3.
3 brownies for each person.

A shop sells fence panels with a wooden frame going all the way round each panel. The price of each panel is based on the area o

vagabundo [1.1K]

Answer:

a) Each 1m² of fence panel costs: £2

b) I metre of wooden frame costs: £1

Step-by-step explanation:

Let the price of 1 sq.m. of fence panel be x

Let the price of 1 m of wooden frame be y

In Fig 1

Length = 4 m

Breadth = 3 m

Area = $Length \times breadth = 4 \times 3 = 12 sq.m.$

Cost of 1 sq.m. = x

Cost of 12 sq.m. = 12x

Perimeter =2(l+b)=2(4+3)=14 m

Cost of 1 m of wooden frame = y

Cost of 14 m of wooden frame = 14y

We are given that total cost of framing and fencing is 38

So. 12x+14y=38 ----1

In Fig 2

Length = 6 m

Breadth = 2 m

Area = $Length \times breadth = 6 \times 2 = 12 sq.m$ .

Cost of 1 sq.m. = x

Cost of 12 sq.m. = 12x

Perimeter =2(l+b)=2(6+2)=16 m

Cost of 1 m of wooden frame = y

Cost of 16 m of wooden frame = 16y

We are given that total cost of framing and fencing is 40

So. 12x+16y=40---2

Substitute the value of 12x form 1 in 2

38-14y+16y=40

2y=2

y=1

Substitute the value of y in 2

12x+16=40

12x=24

x=2

So, cost of 1 sq.m. of fence panel is 2 and cost of 1 m of wooden frame is 1

In fig 3

To verify :

Length = 3 m

Breadth = 5 m

Area = $Length \times breadth = 3 \times 5 = 15 sq.m.$

Cost of 1 sq.m. = 2

Cost of 12 sq.m. = $15 \times 2 = 30$

Perimeter =2(l+b)=2(3+5)=16 m

Cost of 1 m of wooden frame = 1

Cost of 16 m of wooden frame = 16

So, Total cost = 30+16=46

We are given that cost of fencing and framing is 46

Thus verified

Hence

a) Each 1m² of fence panel costs: £2

b) I metre of wooden frame costs: £1

Giving brainliest to best answer! I need both of these done by 10:50! Pls help!

goblinko [34]

<h3>Answer:</h3>

Option B
Option A

<h3>Solution:</h3>

Multiply the numerator of the first fraction times the numerator of the second fraction:
2•4=8
Same with the denominators:
8•5=40
Hence, the fraction is 8/40.
Now, let's simplify the second pair of fractions:
2•3=6
6•5=30
Answer: 6/30

Hope it helps.
