Answer:

1/2

Step-by-step explanation:

There are a total of 25 students. 3 don't study art or biology. 10 study only biology. 6 study both art and biology. This means the remaining students only study art.

1. Calculate the number of students taking art

only art: 25 - 3 - 6 - 10 = 6

number of students taking art and biology: 6

total number of students taking art: 12

2. Calculate the probability

Out of the 12 total students taking art, 6 are in art and biology.

6/12 = 1/2

Ludmilka [50]

Answer:

Step-by-step explanation:

rate  = 3.5% per month

A) Six  days later the bank calculated the daily interest.

so, time = 6 days

= 6 / 30 = 1/5 month

simple interest  =\frac{P*r*t}{100}

=\frac{5000*3.5*1/5}{100} \\\\=35

=35%

B) For $5000, t = 1 month

For $2000, t = 20 / 30 = 2/3 month

For $8000, t = 16/30 months

Simple interest for $5000

=\frac{500083.5*1}{100} \\\\= 175

$175

Simple interest for $2000

=\frac{2000*3.5*2/3}{100} \\\\=\ 46.67

=$46.67

Simple interest for $8000

=\frac{8000*3.5*16/30}{100} \\\\=149.33

=$149.33

Total amount in account at the end of 30 days is

= $5000 + $175 + $2000 + $46.67 + $8000 + $149.33

= $15371

Show how to solve the problem 378×6 using place value with regrouping. Explain how you knew when to regroup
nekit [7.7K]
<span>1. 6 (378) = 2268 = (189 + 189)6


Properties are:
Addition, you can have 6 + 107 = 113 </span>
<span>Commutative Property by moving: 107 + 6 = 113 </span>
<span>Associative Property by grouping: (3 + 3) + (100 + 7 ) = 113 </span>
<span>Distributive Property by allotting: 2 (3) + 107 = 113   </span>

<span>Multiplication, you can have 6 x 107 = 642 </span>
<span>Commutative Property by moving: 107 x 6 = 642 </span>
<span>Associative Property by grouping: (3 + 3) x (100 + 7 ) = 642 </span>
<span>Distributive Property by allotting: 2(3) x 107 = 642<span>

Lexi picked 2 7/10 pounds of strawberries. That afternoon, Lexi’s sister ate 7/8 of the strawberries. How many pounds of strawbe
gavmur [86]

3\frac{3}{35} pound of strawberry

Step-by-step explanation:

Given parameters:

    Pounds of strawberry picked by Lexi =2 \frac{7}{10}

    Pounds of strawberry eaten by Lexi sister = \frac{7}{8}

Unknown:

Pound of strawberry Lexi's sister ate = ?

Solution:

This is a fraction word problem.

  Let pound of strawberry eaten by Lexi's sister = K

We can establish that:

  Pound of strawberry eaten by Lexi sister x K = Pound of strawberry picked by Lexi

Mathematically we have:

         \frac{7}{8} x K = 2 \frac{7}{10}

#learnwithBrainly

             K =  \frac{27 x 8}{10 x 7} = \frac{216}{70}

            K = 3\frac{3}{35} pound of strawberry
