The histogram shows the numbers of floors in several tall buildings in New york city A.10 B.11 C.41 D.55

scZoUnD [109]

Answer:

10 buildings

Step-by-step explanation:

<em>Incomplete question: Missing Attachment</em>

<em>I will answer your question with the attached histogram</em>

<em></em>

Required

Determine the number of tall buildings that had more than 60 floors

The histogram can be interpreted as follows:

$\begin{array}{cccccc}{Floors} & {1-20} & {21-40} & {41-60} & {61-80} \ \\ {Buildings} & {10} & {5} & {15} & {10} \ \end{array}$

More than 60 floors is represented with the following group: 61 - 80

The frequency of group 61 - 80 is 10

<em>Hence, 10 buildings had more than 60 floors</em>

Mr. Yarmus purchased 3 cups of coffee for his friends. He paid $7.29 in yoyal, including and 8 percent sales tax. What was the c

Nonamiya [84]

Answer:

$2.25 price with per coffee without tax

Step-by-step explanation:

3 cups of coffee = $7.29 (with tax)

tax = 8% = 8/100 = 0.08 (NOTE: % means 1/100)

Total amount = a

Price for 3 cups without tax = p

tax of price for coffee = t

8% tax with coffee = p+p*0.08

How does the equation work, for example:

p = 10

p*0.08 = 0.8

p+p*0.08 = 10+0.8= 10.8 // price with tax

a = p + t

7.29 = p + 0.08p //Combine like terms

7.29 = 1.08p //Divide both sides by 1.08

7.29/1.08 = p

6.75 = p //Price of all 3 coffee without tax

6.75 = 3p //Finding price of 1 coffee without tax

6.75/3 = p

2.25 = p

Now finding total amount of per coffee with tax:

a = p + t

a = 2.25 + 2.25*0.08

a = 2.25 + 0.18

a = 2.43

Checking:

a = 2.43 //Price of per coffee with tax

a = 3(2.43) = 7.29 // Price of all 3 coffee with tax

//Hope it helps and it's right.

What is the value a and b in<br> The equation<br><br> a(3x -8)=b-18x

Misha Larkins [42]

Answer:

$a=\frac{b-18x}{3x-8}\\b=3ax-8a+18x$

Step-by-step explanation:

<u>Solving for A:</u>

$a(3x-8)=b-18x$ - Given

$\frac{a(3x-8)}{(3x-8)}=\frac{b-18x}{(3x-8)}$ - Divide both sides by 3x-8 to isolate a

$a = \frac{b-18x}{3x-8}$ - Simplify

<u>Solving for B:</u>

<u /> $a(3x-8)=b-18x$ - Given

$3ax-8a=b-18x$ - Distribute the parenthesis (distributive property)

$3ax-8a+18x=b$ - Add 18x to both sides to isolate b

A baseball is thrown into the air with an upward velocity of 30 ft/s. its initial height was 6 ft, and its maximum height is 20.

marissa [1.9K]

Check the picture below.

where is the -16t² coming from? that's Earth's gravity pull in feet.

$\bf ~~~~~~\textit{initial velocity} \\\\ \begin{array}{llll} ~~~~~~\textit{in feet} \\\\ h(t) = -16t^2+v_ot+h_o \end{array} \quad \begin{cases} v_o=\stackrel{30}{\textit{initial velocity of the object}}\\\\ h_o=\stackrel{6}{\textit{initial height of the object}}\\\\ h=\stackrel{}{\textit{height of the object at "t" seconds}} \end{cases} \\\\\\ h(t)=-16t^2+30t+6 \\\\[-0.35em] ~\dotfill$

$\bf \textit{vertex of a vertical parabola, using coefficients} \\\\ h(t)=\stackrel{\stackrel{a}{\downarrow }}{-16}t^2\stackrel{\stackrel{b}{\downarrow }}{+30}t\stackrel{\stackrel{c}{\downarrow }}{+6} \qquad \qquad \left(-\cfrac{ b}{2 a}~~~~ ,~~~~ c-\cfrac{ b^2}{4 a}\right)$

$\bf \left(-\cfrac{30}{2(-16)}~~,~~6-\cfrac{30^2}{4(-16)} \right)\implies \left( \cfrac{30}{32}~,~6+\cfrac{225}{16} \right)\implies \left(\cfrac{15}{16}~,~\cfrac{321}{16} \right) \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill (\stackrel{\stackrel{\textit{how many}}{\textit{seconds it took}}}{0.9375}~~,~~\stackrel{\stackrel{\textit{how many feet}}{\textit{up it went}}}{20.0625})~\hfill$
