Answer:

The answer to your question is:

Step-by-step explanation:

Q1. They are vertical angles, so they measure the same

[2(x + 10)] = (3x - 30)

2x + 20 = 3x -30

2x - 3x = -30 - 20

- x = - 50

x = 50

Q2. They are also vertical angles, so they measure the same.

[6(x - 2)] = 3x + 30

6x - 12 = 3x + 30

6x - 3x = 30 + 12

3x = 42

x = 42/3

x = 14

∠DHG = 6(14 - 2)

∠DHG = 6(12)

∠DHG = 72

A football is kicked into the air. The height of the football can be modeled by the equation

Alinara [238K]

Answer:

x = 0 and x = 1

Step-by-step explanation:

Given that,

A football is kicked into the air. The height of the football can be modeled by the equation :

$h = -16x^2 + 16x$

Where

h is the height reached by the ball after x seconds

When it touches the ground, h = 0

So,

$-16x^2 + 16x=0\\\\16x(-x+1)=0\\\\x=0\ and\ x=1$

So, it will touch the ground at x = 0 and x = 1 seconds.

Natalie and John are both saving coins in jars for a rainy day. Natalie currently has 1 1/8 jars of coins, and John has 9/14 of

aivan3 [116]

Answer:

Natalie will have $1\frac{43}{56}$ jars of coins all together after receiving John's coins.

Step-by-step explanation:

Given that:

Coins Natalie have = $1\frac{1}{8}$ jars of coins

Coins John have = $\frac{9}{14}$ jars of coins

When John will give all his coins to Natalie.

Total coins Natalie have = Her coins + John's coins

Total coins Natalie have = $1\frac{1}{8}+\frac{9}{14}$

Total coins = $\frac{9}{8}+\frac{9}{14}$

Total coins = $\frac{63+36}{56}=\frac{99}{56}$

Total coins = $1\frac{43}{56}$

Hence,

Natalie will have $1\frac{43}{56}$ jars of coins all together after receiving John's coins.
