What is the length of line segment BC?​
Nezavi [6.7K]

Answer:

d. 10.53 units

Step-by-step explanation:

This question could be answered by Pythagoras Theorem which is :

a^{2} +b^{2} =c^{2} In every triangle c is always the hypotenuse ( which is the longest line in the triangle/ the line where the right angle sign is pointing to )

a or b could be either one of the other lines of the triangle it doesn't matter.

First you find AC which is simply by adding the two 5.2 values which is 10.4 units.

BC can be written as b in our Pythagoras equation and if you first substitute it you will have:

10.4^{2} + b^{2} = 14.8^{2}

To find b you rearrange everything to the other side except b

b=\sqrt{14.8^{2}-10.4^{2}  }

And if you type that in the calculator you get

BC= 10.53 units (2 decimal place)

Hope it is right, and ask any questions if unsure :)))

Miriam is going to the county fair. Each ride ticket costs $2 and admission costs $7. Miriam has $25 to spend at the fair.
Talja [164]

Answer:

9

Step-by-step explanation:

Given data

Ride ticket= $2

Admission= $7

Amount= $25

We want to find the greatest number of rides

let the number of rides be x

The expression to describe how she spends the amount is given as

y=7+2x

for y= 25, let us find x

25= 7+2x

25-7= 2x

18=3x

x= 18/2

x= 9

Hence the number of rides is 9

Pls help pls ill give u a braniest if you help me
alexandr1967 [171]

Answer:

B

Step-by-step explanation:

y = (x + 1)/x

xy = x + 1

xy - x = 1

x(y - 1) = 1

x = 1/(y - 1)

Interswitch variables

f^-1(x) = 1/(x - 1)
