Harper picked 3.5 baskets of apples. Cooper picked 4 1/4 baskets of apples did Harper and cooper pick together? Express your ans

ioda

Answer:

The number of basket of apples picked by Harper and Cooper together is $5\frac{1}{4} \ \ Or \ \ 5.25$ .

Step-by-step explanation:

Given:

Number of basket picked by Harper = 3.5

Number of basket picked by cooper = $4\frac{1}{4}$

We need to find the number of basket of apples picked by Harper and Cooper together.

Solution:

Now we can see that one number is in decimal form and other number is in mixed fraction form so we will convert both the number in simplest fraction form and then solve the same.

Number of basket picked by Harper = 3.5

Now if we divide 7 from from 2 we get the answer as 3.5 so we can say that;

3.5 can be rewritten as $\frac{7}{2}$

Number of basket picked by Harper = $\frac{7}{2}$

Number of basket picked by cooper = $4\frac{1}{4}$

$4\frac{1}{4}$ can be rewritten as $\frac{17}{4}$

Number of basket picked by cooper = $\frac{17}{4}$

Now we can say that;

to find the number of basket of apples picked by Harper and Cooper together we will add Number of basket picked by Harper and Number of basket picked by cooper.

framing in equation form we get;

number of basket of apples picked by Harper and Cooper together = $\frac{7}{2}+\frac{17}{4}$

now we will use LCM to make the denominator common we get;

number of basket of apples picked by Harper and Cooper together = $\frac{7\times2}{2\times2}+\frac{17\times1}{4\times1}=\frac{14}{4}+\frac{17}{4}$

Now denominators are common so we will solve the numerators we get;

number of basket of apples picked by Harper and Cooper together = $\frac{14+7}{4} = \frac{21}{4} \ \ Or\ \ 5\frac{1}{4} \ \ Or \ \ 5.25$

Hence the number of basket of apples picked by Harper and Cooper together is $5\frac{1}{4} \ \ Or \ \ 5.25$ .

Ann-Marie is comparing costs at two locations for an event. Location 1 charges $100 per hour and $20 per person. Location 2 char

Serga [27]

Answer:

We must have less than 10 guests

Step-by-step explanation:

Location 1

cost = 100h+20p where h = hours and p = person

Location 2

cost = 600 for p < 25

Since there are less than 25 guests and h = 4 both equations are valid

Location 1

cost = 100(4)+20p = 400+20p

Location 2

cost = 600

We want location 2 to be less expensive

600< 400+20p

Subtract 400 from each side

600-400 < 20p

200 <20p

Divide by 20

200/20 < 20p/20

10 <p

We must have less than 10 guests

A classroom has ten students. Three students are freshman, two are sophomores, and five are juniors. Three students are randomly

ycow [4]

Answer:

0.25

Step-by-step explanation:

We have a total of ten student, and three students are randomly selected (without replacement) to participate in a survey. So, the total number of subsets of size 3 is given by 10C3=120.

On the other hand A=Exactly 1 of the three selected is a freshman. We have that three students are freshman in the classroom, we can form 3C1 different subsets of size 1 with the three freshman; besides B=Exactly 2 of the three selected are juniors, and five are juniors in the classroom. We can form 5C2 different subsets of size 2 with the five juniors. By the multiplication rule the number of different subsets of size 3 with exactly 1 freshman and 2 juniors is given by

(3C1)(5C2)=(3)(10)=30 and

Pr(A∩B)=30/120=0.25
