Answer:

         \large\boxed{\large\boxed{8.06units}}

Explanation:

The figure is a right triangle with:

  • hypotenuse = segment AC
  • vertical leg = 7 units
  • horizontal leg = 4 units

Hence, you must use Pythagora's theorem, which is valid for all right triangles:

             hypotenuse^2=(leg_1)^2+(leg_2)^2

Substituting the data:

        hypotenuse^2=(7unit)^2+(4unit)^2=49unit^2+16unit^2=65unit^2

Square root both sides:

         hypotenuse=\sqrt{65unit^2}=8.06unit

Eric orders 3 large cheese pizzas. There is a $2 delivery fee for each pizza.He pays a total of $42.Which equation can be used t
ad-work [718]

Answer:

3(x+2)=42

Step-by-step explanation:

So lets go over what we know:

There are 3 large pizzas

Each pizza has a addition cost of 2 dollars

The total cost is 42 dollars

We need to find the cost per pizza.

Now lets piece together our equation.

We know that the pizzas equal 42 dollars so we can immediately put 42 on the opposite side of the equal side:

=42

We also know that each of the 3 pizzas cost 2 dollars. This would go on the left side of the equation:

6=42
Now, we know x is the amount of pizzas. There are 3 pizzas, or in other words, 3x. We can add this to the left side of the equation, because the 3 pizzas plus the 6 dollars equals the total of 42 dollars:

3x+6=42

There are no answers above that look like this, however. This is because we have to factor the left side of the equation.

A factor of both 3 and 6 is 3. So we can factor out 3 and we get:

3(x+2)=42

This looks like the first answer!
Hope this helps! :3

\bf 400,000,000\implies 4\times 10^8 \\\\[-0.35em] ~\dotfill\\\\ \cfrac{\textit{desktop users}}{\textit{mobile users}}\qquad \qquad \cfrac{1.2\times 10^9}{4\times 10^8}\implies \cfrac{12\times 10^8}{4\times 10^8}\implies \cfrac{12}{4}\times\cfrac{10^8}{10^8}\implies \cfrac{3}{1}

3 : 1, or 3 to 1, thus 3 times as many.

the base of a ten foot ladder stands six feet from a house. How many feet up the house does the ladder reach
Ludmilka [50]
In this problem you will need to use the Pythagorean theorem (c^2=a^2+b^2).
The a and b represents the two edges, while c is the diagonal side and it is called the hypotenuse. Since you already know what the hypotenuse is and what one of the sides already are you just have to use the problem: c^2-a^2=b^2. Then if you plug the data you already have into the problem you will get 10^2-6^2=b^2. That then equals 100-36=b^2. Then you subtract and get b^2=64. Then you square root both sides and you get the answer b=8.
