Mathematics

Answer:

The first one (the one with the months)

Step-by-step explanation:

A function is when an x value doesn't have more that one y value (y can have more than one x value, though). On the teachers and pets one, Ms. Valverde has two pets, so that doesn't count. On the shapes one, the orange square is pointing to another orange square and a triangle, so that doesn't count. The last one has 7 equaling to 12 and 13, so that doesn't count. The one with the months doesn't have any x values with more than one y value, so it is a function.

Oksana_A [137]

Answer:

7%

Step-by-step explanation:

(15/220) x 100 = 6. 8182 = 7%

to convert to percentage multiply by 100

To convert to the nearest whole number, look at the first number after the decimal. If it is greater or equal to 5, add 1 to the number after the decimal. 8 is greater than 5, so add one to 6

Find the Lateral area for the regular pyramid. (Keep it as a Square Root)
Shtirlitz [24]

1. You must apply the following formula: 


 LA=<span>1/2 ×(Perimeter of the base)(Slant length)</span>

<span>
</span>

<span> 2. The slant length is (By </span><span> the Pythagorean Theorem):</span>

<span> a</span><span>^2=b^2+c^2</span>

<span> </span><span>a= b^2+c^2</span>

<span> a</span><span>=</span><span>√(</span><span>1^2+3^2)</span>

<span> </span><span>a=√10</span>

<span>
</span>

<span> 3. </span><span>The p</span><span>erimeter of the base is:</span>

<span>
</span>

<span> </span><span>P=2+2+2+2</span>

<span> </span><span>P=8</span>

<span>
</span>

<span> 4. </span><span>Then, you have:</span>

<span>
</span>

<span> LA=</span><span>1/2 ×(Perimeter of the base)(Slant Length)</span>

<span> LA=</span><span>1/2 ×(8)(</span><span>√</span><span>10)</span>

<span> LA=</span><span>(</span><span>8√10)/2</span>

<span> LA=</span><span>4√10</span>

If 27^27+27^27+27^27=3^k<br> What is k?
JulijaS [17]

Answer:

\large{\boxed{k=82}}

Step-by-step explanation:

27^{27}+27^{27}+27^{27}=3^k

3 \cdot 27^{27}=3^k

3 \cdot (3^3)^{27}=3^k

3 \cdot 3^{81}=3^k

3^{82}=3^k \implies k=82

Ray SU is an angle bisector of ∠RST. The measure of ∠TSU is 42°. What is the measure of ∠RST?
olchik [2.2K]
If we were to focus only on <RSU, the measure would be the same as <TSU, which is 42 degrees. However, because it is asking for the entire angle (<RST), the measure would be doubled. The measure of <RST is 84.
