PLEASE HELP, 10TH GRADE GEOMETRY (REAL ANSWERS PLSSSS)
Zina [86]

Answer:

The correct option is 4.

Step-by-step explanation:

Let the line AB divided into 7 equal parts.

It is given that point P partitions the directed line segment from A to B in 3:4. It means 3 parts are before P and 4 partes are after P.

It is given that point Q partitions the directed line segment from A to B in 4:3. It means 4 parts are before Q and 3 partes are after Q.

It is given that point R partitions the directed line segment from A to B in2:5. It means 2 parts are before R and 5 partes are after R.

It is given that point S partitions the directed line segment from A to B in 5:2. It means 5 parts are before S and 2 partes are after S.

From the below figure we can say that point S is closest to point B.

It is also written as

A

A

Therefore option 4 is correct.

h=-16t^2+36t+4\implies \stackrel{h}{0}=4(-4t^2+9t+1)\implies 0=-4t^2+9t+1 \\\\[-0.35em] ~\dotfill\\\\ ~~~~~~~~~~~~\textit{quadratic formula} \\\\ 0=\stackrel{\stackrel{a}{\downarrow }}{-4}t^2\stackrel{\stackrel{b}{\downarrow }}{+9}t\stackrel{\stackrel{c}{\downarrow }}{+1} \qquad \qquad t= \cfrac{ - b \pm \sqrt { b^2 -4 a c}}{2 a}

t= \cfrac{ - (9) \pm \sqrt { (9)^2 -4(-4)(1)}}{2(-4)} \implies t = \cfrac{ -9 \pm \sqrt { 81 +16}}{ -8 } \\\\\\ t= \cfrac{ -9 \pm \sqrt { 97 }}{ -8 }\implies t=\cfrac{9\mp\sqrt{97}}{8}

Which equation could be used to find the length of the hypotenuse?
nevsk [136]

The equation which could be used to find the length of the hypothenuse is; 5 squared + 8 squared = c squared.

<h3>Which equation could be used to find the length of the hypothenuse?.</h3>

It follows from the task content that the equation which could be used to find the length of the third side be determined.

Hence, since it follows from Pythagoras theorem that the square of the hypothenuse is equivalent to the sum of the squares of the two other sides of a right triangle.

Hence, the required equation is; 5 squared + 8 squared = c squared.

I have 25 coins in my pocket all of which are 5 penny or 20 penny coins. if their total value is 2.90 pounds how many penny coin
Jlenok [28]

Answer:

  • 14 coins of 5p
  • 11 coins of 20p

Step-by-step explanation:

<u>Given</u>

  • 5p coins = x
  • 20p coins = y
  • Total = 2.90 = 290 p
  • Number of coins = 25

<u>Equations</u>

  • x + y = 25
  • 5x + 20y = 290 ⇒ x + 4y = 58

<u>Consider the first equation in the second one</u>

  • x + y + 3y = 58
  • 25 + 3y = 58
  • 3y = 33
  • y = 11

<u>Then x is</u>

  • x = 25 - 11 = 14

<u>Answer</u>

  • 14 off 5p coins and 11 off 20p coins
