Mathematics

Answer:

A is 1 in 100 and b is 1 in 25

Step-by-step explanation:

there are 10 digits (1, 2, 3, 4, 5 ,6 ,7 ,8 ,9, 0).

that gives you a 1 in 10 chance but there are 2 and to get both of them, you do 1 in 10 x 1 in 10 which is 1 in 100. if you know that they are both even, this limits it to a 1 in 5 twice, 1 in 5 x 1 in 5 is 1 in 25.

Jenna spends $15.04 at the store on notebooks and folders for school. Notebooks cost $4.85 each, and folders cost $0.89 each. Sh
cluponka [151]

Answer:

\boxed{\text{2 notebooks and 6 folders}}

Step-by-step explanation:

Let n = number of notebooks

and f = number of fodders

You have a system of two equations:

\begin{cases}(1)& 4.85n + 0.89f = 15.04\\(2) & n+ f = 8\end{cases}\\\\

\begin{array}{lrcll}(3) & f & = & 8-n &\text{Subtracted n from each side of (2)}\\& 4.85n+0.89(8-n) & = & 15.04 &\text{Substituted (3) into (1)}\\& 4.85n+7.12-0.89n & = & 15.04 &\text{Distributed 0.89}\\& 3.96n+7.12 & = & 15.04 &\text{Combined like terms} \\& 3.96n & = & 7.92 & \text{Subtracted 7.12 from each side} \\(4) & n & = & 2 & \text{Divided each side by 3.96}\\& 2+ f & = & 8 & \text{Substituted (4) into (2)}\\& f & = & 6 &\text{Subtracted 2 from each side} \\\end{array}

Jenna bought \boxed{\textbf{two notebooks and six folders} }.

Check:

\begin{array}{rclcrcl}4.85\times2+0.89\times6 & =& 15.04 & \qquad &2+6&=&8\\9.70+5.34 & = & 15.04 & \qquad &8&=&8\\15.04& = & 15.04 & & & & \\\end{array}

OK.

Two ships leave port at the same time. Ship A sails north at a speed of 10 mph while ship B sails east at a speed of 35 mph. Fin
blondinia [14]

Answer:

  d = (5√53)t

Step-by-step explanation:

After 1 hour, A is 10 miles north of the port, and B is 35 miles east of the port. Since these directions are at right angles, the Pythagorean theorem can be used to find the distance between the ships:

  d = √(10² +35²) = √(100 +1225) = √1325 = 5√53 . . . . miles

The distance between the ships is increasing this number of miles each hour, so the desired expression is ...

  d = (5√53)t ≈ 36.4t
