We know two angles of a triangle, ∠A = 65° and ∠B = 58°, and we have to identify the longest side.
The longest side will be the one that is opposite to the widest angle. In our case, we don't know the measure of C, but we know that the sum of the three measures has to be 180°, so we can calculate it as:
[tex]\begin{gathered} m\angle A+m\angle B+m\angle C=180\degree \\ 65+58+m\angle C=180 \\ m\angle C=180-65-58 \\ m\angle C=57\degree \end{gathered}[/tex]As the widest angle is at vertex A, the longest side will be its opposite, which correspond to the side formed by the other two vertices: B and C.
The longest side is BC.

We know that
• Hernandez bought 640 t-shirts.

To know how many packs he bought, we just need to divide

Last Monday, two law students met up at Café Literatura after school to read the pages they were assigned in the Legal Methods class. Alejandro can read 1 page per minute, and he has read 28 pages so far. Carly, who has a reading speed of 2 pages per minute, has read 12 pages so far. Part A: Define the variables and write two equations to represent the number of pages that each student read. DE 4 Variables: X-Minutes they real they head Alejandro:X-XF28 x= Number of payes Carly:apGraph both equations , find when Alejandro has read more pages than Carly, and when they have read the same amount of pages.
Answers
Let t be the time and P be the number of pages that each students has read. In both cases, the equation that relates P and t is a linear equation. The slope-intercept form of the equation of a line is:
[tex]y=mx+b[/tex]Where m represents the rate of change of y with respect to x and b represents the initial value when x=0.
In this case, where P represents the number of pages and t represents the time, the relation can be written as:
[tex]P=mt+b[/tex]Adjust the paramenters m and b for each student.
Since Alejandro can read 1 page per minute, then the rate of change of the number of pages with respect to time is 1. Since he has read 28 pages so far, then the initial value is 28. The number of pages that Alejandro reads, is:
[tex]P=t+28[/tex]Since Carly can read 2 pages per minute, the rate of change is 2. Since she has read 12 pages so far, the initial value is 12. The equation for Carly, is:
[tex]P=2t+12[/tex]To graph each equation, evaluate it on two different values of t to find the corresponding values of P.
For Alejandro, let's use t=0 and t=1:
[tex]\begin{gathered} t=0\Rightarrow P=0+28\Rightarrow P=28 \\ t=1\Rightarrow P=1+28\Rightarrow P=29 \end{gathered}[/tex]Plot the points (0,28) and (1,29) in a coordinate plane:
Then, draw a line through them:
Do the same for Carly's equation. We can see that two points on the line would be (0,12) and (1,14):
To find when has Alejandro read more pages than Carly, write an inequality. After t minutes, Alejandro has read t+28 pages, and Carly has read 2t+12 pages. We want t+28 to be greater than 2t+12, then:
[tex]t+28>2t+12[/tex]Substract t from both sides:
[tex]\begin{gathered} t+28-t>2t+12-t \\ \Rightarrow28>t+12 \end{gathered}[/tex]Substract 12 from both sides:
[tex]\begin{gathered} 28-12>t+12-12 \\ \Rightarrow16>t \end{gathered}[/tex]Therefore, whenever t is less than 16 minutes, Alejandro has read more pages than Carly.
Notice that if we replace the ">" sign for a "=" sign, we would find that they have read the same amount of pages when t=16 minutes.

The outstanding balance on each account can be summarized using the mean, median, and mode since it is quantitative data.
Options A, B, and C are correct here.
Part B
The name of credit cards can only be summarized by frequency. That is, how many belong to each company (i.e. MasterCard, Visa, American Express, etc.)
The only correct option here is Mode. (Option A).

To do so, let's find the LCM (Least Common Multiple) between our different denominators (In this case, 2 and 4)
The LCM is 4. Now, we need to find a way for all our fractions to have 4 as a denominator. Notice that we can do so by multiplying both 3/2 by 2 (both in the numerator and denominator), as following:
[tex]\begin{gathered} \frac{3}{2}+\frac{1}{4}+\frac{3}{2}\rightarrow\frac{2\cdot3}{2\cdot2}+\frac{1}{4}+\frac{2\cdot3}{2\cdot2} \\ \\ \rightarrow\frac{6}{4}+\frac{1}{4}+\frac{6}{4} \end{gathered}[/tex]Now, we can add them up:
[tex]\frac{6}{4}+\frac{1}{4}+\frac{6}{4}\rightarrow\frac{6+1+6}{4}\rightarrow\frac{13}{4}[/tex]This way, the answer is 13/4
The base of the pyramid is a square.158Perimeter of the base =Area of the base =Slant height =Lateral area =square unitsSurface area =square unitsBlank 1:Blank 2:Blank 3:Blank 4:Blank 5:
Answers
The pyramid has a square base.
i) Perimeter of the base implies the perimeter of the square.
Perimeter of a square is given as:
[tex]\begin{gathered} P=4L \\ L=8 \\ P=4\times8 \\ =32 \end{gathered}[/tex]ii) Area of the base implies the area of the square.
Area of a square is given as:
[tex]\begin{gathered} A=L^2 \\ L=8 \\ A=8^2 \\ A=64 \end{gathered}[/tex]iii) The slant height can be obtained by using the pythagoras theorem.
From the diagram, the hypotenuse side is the unknown slant height, the other two(2) sides are of length 15 and 8.
Thus, we have:
[tex]\begin{gathered} H^2=O^2+A^2\text{ (Pythagoras theorem)} \\ H^2=15^2+8^2 \\ H^2=225+64 \\ H^2=289 \\ H=\sqrt[]{289} \\ H=17 \end{gathered}[/tex]Hence, the slant height is 17
iv) The lateral area of a square pyramid is the sum of the areas of all its 4 triangular side faces.
The area of a triangle is given as:
[tex]\begin{gathered} A=\frac{1}{2}\times Base\times Height \\ \text{Base}=8;\text{ Height=15} \\ A=\frac{1}{2}\times8\times15 \\ A=\frac{120}{2} \\ A=60 \\ \text{Hence, the lateral area is 4}\times60\text{ ( since there are 4 triangular faces)} \\ \text{Lateral area= 240} \end{gathered}[/tex]v) The surface area is the sum of the lateral area and the base area.
The lateral area has been obtained to be 240.
The base area has been obtained to be 64.
Thus, the surface area = 240 + 64
Hence, the surface area is 304
