BRAINLIEST PLS HELP ASAP!!!

Mathematics
1 answer:
andrew11 [14]3 years ago

Answer:

fourth option

Step-by-step explanation:

let t be tennis balls and g be golf balls, then

5t + 3g = 70 → (1)

2t + 5g = 85 → (2)

Multiplying (1) by 5 and (2) by - 3 will eliminate g

25t + 15g = 350 → (3)

- 6t - 15g = - 255 → (4)

Add (3) and (4) term by term to eliminate g

19t = 95 ( divide both sides by 19 )

t = 5

Substitute t = 5 into either of the 2 equations and solve for g

Substituting into (1)

5(5) + 3g = 70

25 + 3g = 70 ( subtract 25 from both sides )

3g = 45 ( divide both sides by 3 )

g = 15

Thus

$5 for tennis balls and $15 for golf balls

Dimas [21]

Answer:

Equilateral Triangle

Side a = 1

Side b = 1

Side c = 1

Angle ∠A = 60° = 1.0472 rad = π/3

Angle ∠B = 60° = 1.0472 rad = π/3

Angle ∠C = 60° = 1.0472 rad = π/3

C=60°B=60°A=60°b=1a=1c=1

Area = 0.43301

Perimeter p = 3

Semiperimeter s = 1.5

Height ha = 0.86603

Height hb = 0.86603

Height hc = 0.86603

Median ma = 0.86603

Median mb = 0.86603

Median mc = 0.86603

Inradius r = 0.28868

Circumradius R = 0.57735

Helppppp!!!!<br> I don’t understand it
oksian1 [2.3K]
Okay so for 2x-y > 3
Subtract -2 from each side
-y>-2x+3
Divide by -1
And when you divid you gotta switch signs
So it’s y<2x-3

3x-5y less than and equal to 25
Subtract 3
-5y is less than and equal to -3x+25
Then divide by -5
Flip since we divide
Y more than and equal to 3/5x-5
We always flip signs when we divid or multiple
I hope this help
Sorry if I’m wrong

baherus [9]

Answer:

The interval estimate is above 70%, so infer that it will be supported.

Step-by-step explanation:

The evidence that 95% confidence interval estimating the proportion of students supporting the fee increase is [0.75, 0.85] supports university officials' claim that at least 70% of the voting student population supports a fee increase.

Therefore we can infer that a fee increase will be supported.
