Hayden bought 48 new trading cards three-fourths of the new cards. How many baseball cards did Hayden buy?

2 answers:

6 0

You need to divide 48 with 4 since 3/4 is being divided also. Once you do that, multiply by 3 to get the 3 parts of the whole fraction. Hope this helps. (P.s. I didn’t get the part when you said, “...? new trading cards THREE FOURTHS of the new cards.”)

Area of pond:

A= $\pi r^{2}$

r=1,5m

A=3,142*1,5*1,5=7,0695

Area of pond with path

B= $\pi r^{2}$

r=50 cm+1,5m=0,5m+1,5m=2m

B=3,142*2*2=12,568

Area of path:

12,568-7,0695=5,4985=5,50

A home is to be built on a 56 foot 9 inch wide lot. The house is 5 feet 5 inches from the side of the lot and is 34 feet 10 inch

Anni [7]

Check the picture below, so the distance of the house from the other side is that blue gap.

so, there are 12 inches in 1 foot, so let's just convert all those feet to inches and subtract them.

$\bf 56'\implies (56\cdot 12)''\implies 672''
\\\\\\
5'5''\implies (5\cdot 12+5)''\implies 65''
\\\\\\
34'10''\implies (34\cdot 12 + 10)''\implies 418''\\\\
-------------------------------\\\\
672''-(65+418)''\implies 189''\implies 15'9''$

Suppose you asked 100 commuters how much they spend each year and obtained a mean of $167 spent on transportation and a standard

Lena [83]

Answer:

The correct answer is "$159 and $175".

Step-by-step explanation:

The give values are:

Mean,

= $167

Standard deviation,

$\sigma$ = $40

Number of commuters,

n = 100

Now,

⇒ $SE=\frac{\sigma}{\sqrt{n} }$

On putting the given values, we get

⇒ $=\frac{40}{\sqrt{100} }$

⇒ $=\frac{40}{10}$

⇒ $=4$

By using the 2 SE rule of thumb, we get

= $$(167 - 2\times 4)$

= $167-8$

= $159$ ($)

Or,

= $(167 + 2\times 4)$

= $167+8$

= $175$ ($)

i.e,

$159 and $175

He would make more money with Susie than by himself because if he only works three hours and Susie make more money than him she would have more but if they work as a team they could split the money and get more together.
