Tammy uses 1 3/4 cups of laundry detergent. The number of loads is 4

<u>Solution:</u>

Given that, Tammy uses 1 3/4 cups of laundry detergent per load.  

When she was finished doing laundry one day.  

She noticed that she had used 7 cups of laundry detergent.  

We have to find how many loads did she do?

Now, we know that, Total cups used can be written as:

<em> </em>number of loads x number of cups per each load = total cups used.

\begin{array}{l}{\text { Then, number of loads } \times 1 \frac{3}{4}=7} \\\\ {\text { Number of loads } \times \frac{1 \times 4+3}{4}=7} \\\\ {\text { Number of loads } \times \frac{7}{4}=7} \\\\ {\text { Number of loads }=7 \times \frac{4}{7}=4}\end{array}

Hence, the number of loads are 4.

A rock is thrown upward with an initial velocity of 16 ft/s from an initial height of 5 ft. How much time does it take for the r
Bogdan [553]
Check the picture below.

so it hits the ground when y = 0, thus

\bf ~~~~~~\textit{initial velocity}\\\\&#10;\begin{array}{llll}&#10;~~~~~~\textit{in feet}\\\\&#10;h(t) = -16t^2+v_ot+h_o&#10;\end{array} &#10;\quad &#10;\begin{cases}&#10;v_o=\stackrel{16}{\textit{initial velocity of the object}}\\\\&#10;h_o=\stackrel{5}{\textit{initial height of the object}}\\\\&#10;h=\stackrel{}{\textit{height of the object at "t" seconds}}&#10;\end{cases}

\bf h(t)=-16t^2+16t+5\implies \stackrel{h(t)}{0}=-16t^2+16t+5&#10;\\\\\\&#10;16t^2-16t-5=0\implies (4t+1)(4t-5)=0\\\\&#10;-------------------------------\\\\&#10;4t+1=0\implies 4t=-1\implies t=-\cfrac{1}{4}\\\\&#10;-------------------------------\\\\&#10;4t-5=0\implies 4t=5\implies t=\cfrac{5}{4}\implies \boxed{t=1\frac{1}{4}}

since "t" is seconds it took, it can't be a negative amount.

You deal a pile of cards, face down, from a standard 52-card deck. What is the least number of cards the pile must have before y
Simora [160]

Answer:

we need at least 17 - card deck

Step-by-step explanation:

From the information given :

We can attempt to solve the question by using pigeonhole principle;

"The pigeonhole principle posits that if more than n pigeons are placed into n pigeonholes some pigeonhole must contain more than one pigeon"

Thus; the minimum number of pigeon; let say at least n pigeons sit on at least one same hole among m hole can be represented by the formula:

m(  n - 1 ) + 1

where ;

pigeons are synonymous to card

pigeonholes  are synonymous to suits

So; m = 4 ; n = 5

∴  4 (5 -1 ) + 1 ⇒ 4 (4) + 1

= 16 + 1

= 17

Hence; we need at least 17 - card deck
