Answer:

<h2> -4 </h2>

Step-by-step explanation:

<em>calculate</em><em> </em><em>the</em><em> </em><em>sum of </em><em>-7</em><em> </em><em>+</em><em> </em><em>3</em><em> </em>

<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em>-|-4|

<em>the</em><em> </em><em>absolute</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>any</em><em> </em><em>number</em><em> </em><em>is </em><em>always</em><em> </em><em>positive</em><em> </em>

<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>-4</em><em> </em><em> </em><em> </em>

<em> </em><em> </em><em>(</em><em>the</em><em> </em><em>negative</em><em> </em><em>sign</em><em> </em><em>outside</em><em> </em><em>the</em><em> </em><em>absolute</em><em> </em><em>value</em><em> </em><em>signs</em><em> </em><em>is</em><em> </em><em>kept)</em>

Answer: -4

Step-by-step explanation: We simplify inside the absolute value as our first step.

-7 + 3 is -4.

So we have -|-4|.

A common mistake at this point in the problem is to change the minus a negative to plus a positive but don't fall into this trap. We must ignore the negative outside the absolute value until our very last step in this problem.

So we take the absolute value of -4 which is 4 and we have -(4).

<u>Remember to bring down the negative!</u>

Notice that I used  around the 4 as it comes out of the absolute value.

So we have -(4) which is 4.

Why is ac smaller than ad if they both look very close
kakasveta [241]

Let's begin by listing out the information given to us:

We start out by observing that Triangles MKR & ACD are similar or proportional

\begin{gathered} MK=21;AC=\text{?} \\ MR=24;AD=28\frac{4}{5} \\ KR=CD=\text{?} \end{gathered}

We will solve for the missing side by using the similar triangle theorem. This is shown below:~

\begin{gathered} \Delta MKR\approx\Delta ACD \\ \frac{MK}{AC}=\frac{MR}{AD} \\ \frac{21}{AC}=\frac{24}{28\frac{4}{5}} \\ \text{Cross multiply, we have:} \\ 24\cdot AC=28\frac{4}{5}\cdot21 \\ AC=\frac{28\frac{4}{5}\cdot21}{24}=25\frac{1}{5} \\ AC=25\frac{1}{5} \end{gathered}

As part of a new advertising campaign, a beverage company wants to increase the dimensions of their cans by a multiple of 1.12.
olga_2 [115]

Answer:

The new can can hold upto volume of 476.69 cubic centimeters.

Step-by-step explanation:

Diameter of the can = d = 6 cm

Radius of the can = r = 0.5d = 0.5 × 6 cm = 3 cm

Height of the can = h = 12 cm

Company wants to increase the dimensions of their cans by a multiple of 1.12. So, the new dimension will be:

r'= 3 cm × 1.12 = 3.36 cm

h' = 12 cm × 1.12 =13.44 cm

Volume of the = can = V

Volume of a cylinder = \pi r^2h

V=\pi r'^2h'

=3.14\times (3.36 cm)^2\times 13.44 cm=476.6808 cm^3\approx 476.68 cm^3

The new can can hold upto volume of 476.69 cubic centimeters.

On a coordinate grid, Ming's house is located 2 blocks to the right and blocks up from (0. 0). Joe's house is located 3 blocks t
kolbaska11 [484]
If o<span>n a coordinate grid, Ming's house is located 2 blocks to the right and (I suppose also 2) blocks up from (0. 0), then the ordered pair that describes the location of Ming's house is (2,2) (moving right 2 units from some point you have to add 2 units to the x-coordinate of the point from which you are moving and moving up 2 units from this point you have to add 2 units to y-coordinate of the point from which you are moving up).
</span>
If Joe's house is located 3 blocks to the right and 2 blocks down from Ming's house, then the ordered pair that describes the location of Ming's house is (2+3,2-2), that is (5,0) <span><span>(moving right 3 units from some point you have to add 3 units to the x-coordinate of the point from which you are moving and moving down 2 units from the point you have to substract 2 units from y-coordinate of the point from which you are moving down)</span>.</span>
