Three side lengths that will form a triangle

3,4,5

This is a Pythagorean triple. It forms a right triangle

3^2 +4^2 = 5^2

9+16=25

25=25

Three side lengths that will not form a triangle

1,2 9

The sum of the two smaller sides must be greater then the third

1+2 < 9 not greater

The marching band sold gift wrap priced at $4.00 per roll for solid colors and $6.00 per roll for print patterns. If they sold 4

Alex Ar [27]

Answer:

The number of gift wrap rolls for solid colors sold was 270 and the number of gift wrap rolls for sprint patterns sold was 210

Step-by-step explanation:

Let

x ---> the number of gift wrap rolls for solid colors sold

y ---> the number of gift wrap rolls for sprint patterns sold

we know that

$x+y=480$ ----> $x=480-y$ ----> equation A

$4x+6y=2,340$ ----> equation B

Solve the system by substitution

substitute equation A in equation B

$4(480-y)+6y=2,340$

solve for y

$1,920-4y+6y=2,340$

$-4y+6y=2,340-1,920$

$2y=420$

$y=210$

<em>Find the value of x</em>

$x=480-y$ ----> $x=480-210=270$

therefore

The number of gift wrap rolls for solid colors sold was 270 and the number of gift wrap rolls for sprint patterns sold was 210

Fatheya and Fatema, along with 30 other people, sign up to audition for a talent show. Contestants are called at random to perfo

galina1969 [7]

So there's 30 people or slots. The odds that Fatheya will be chosen to perform first is 1/30. But now there's one less slot.

Now with Fatema, there's 29 slots, so there's a 1/29 chance. Then combine these values by multiplying them:

1/30 * 1/29 = <em>1/870</em>

All done!

Answer:

I think this is the answer I hope this can help you

Step-by-step explanation:

1) 3 gallons=36 miles

16 gallons=?

so it will be

$36 \times 16 = 576$

$576 \div 3 = 192$

or you can do like this

1 gallons=12 miles so if 16 gallons multiply with 12 it will be 192

2)2 hours=$28.50

? =$99.75

so it will be

$99.75 \times 2 = 199.5$

$199.50 \div 28.50 = 7$

so it will be 7 hours

3) 4.5 km= 5 hours

? =60 hours

$60 \times 4.5 = 270$

$270 \div 5 = 54$

the answer will be 54 kilometer

4) $9.60=3cm

$22.40=?

$22.40 \times 3 = 67.20$

$67.20 \div 9.60 = 7$

7 cm

5) $145.50=50 miles

$552.90=?

$552.90 \times 50 =27645$

$27645 \div 145.50 = 190$

190 miles

6)$239.85=359

$1.95=?

$359 \times 1.95 = 700.05$

$700.05 \div 239.85 = 2.92$

2.92 liter

220=60 hours

?=3 hours

$220 \times 3 = 660$

$660 \div 60 = 11$

11 miles

8)1 gallon= $17.50

8.2 gallon=?

$17.50 \times 8.2 = 143.50$

$143.50

9)7cm=2 minute

? =13 minute

$13 \times 7 = 91$

$91 \div 2 = 45.5$

45.5 cm

10)17=4 acres

? =244 acre

$244 \times 17 = 4148$

$4148 \div 4 = 1037$

1037 kg

11) 1= $2.85

4.4=?

$2.85 \times 4.4 = 12.54$

$12.54

12)

$2.50=5 oz

$32.50=?

$32.50 \times 5 = 162.50$

$162.50 \div 2.50 = 65$

65 oz
