Answer:

7m minutes

Step-by-step explanation:

We know that:

3 days of practice = Monday + Tuesday + Wednesday
Monday = m
Tuesday = m + 6
Wednesday = 5m - 6

Solution:

3 days of practice = Monday + Tuesday + Wednesday
=> 3 days of practice = m + m + 6 + 5m - 6

[Simplifying]

=> 3 days of practice = 7m - 6 + 6

[Final Answer]

=> 3 days of practice = 7m

Hence, the total number of minutes she practiced over the course of the three days is 7m minutes.

Otieno is k years old.He is 5 years older than kidole what will be their age fours to come

EleoNora [17]

Answer:

Otieno's age in 4 years: $k+4$

Kidole's age in 4 years: $k-1$

Step-by-step explanation:

$k$ = Otieno's age

$k-5$ = Kidole's age

Their ages will increase by 4 years when 4 years pass.

$k+4$ = Otieno's age in 4 years

$k-5+4$ = Kidole's age in 4 years

$k-1$ = Kidole's age in 4 years (after simplifying the expression)

Mean Value theorem help! BRAINLIEST if you can explain it clearly!!!

Korolek [52]

$\bf f(x)=ln(x-5)\qquad [6,8]\qquad \cfrac{df}{dx}=\cfrac{1}{x-5}\\\\
-----------------------------\\\\
\textit{mean value theorem}\qquad f'(c)=\cfrac{f(b)-f(a)}{b-a}\\\\
-----------------------------\\\\
f'(c)=\cfrac{1}{c-5}\qquad thus\quad \cfrac{1}{c-5}=\cfrac{f(8)-f(6)}{8-6}
\\\\\\
\cfrac{1}{c-5}=\cfrac{ln(3)-ln(1)}{2}\implies \cfrac{1}{c-5}=\cfrac{ln(3)-0}{2}
\\\\\\
\cfrac{2}{ln(3)}=c-5\implies \boxed{\cfrac{2}{ln(3)}+5=c}$

Nathan has a collection of 220 baseball cards. He lets his brother 1/4 of his collection and sells 20% of his collection to the

tatyana61 [14]

Answer:

The baseball cards remain in Nathan’s collection is 106 cards

Explanation:

Total number of cards Nathan has= 220

Number of cards he let his brother have = 1/4 of his collection

= $\frac{1}{4} \times 220$ = 55 cards

Number of cards he sells = 20% of his collection

= $\frac{20}{100} \times 220$

=44 cards

No of cards he gives to his friends=15 cards

Remaining cards = total number of cards – (no of cards he gave to his brother+ cards he sold+ cards he gave to this friends)

= 220 – ( 55+44+15)

=220-114

=106 cards

baseball cards remain in Nathan’s collection is 106 cards
