As you are looking for 1.75 minutes (or 105 seconds), the best thing to do is to find how many words she can type in 0.25 minutes (this is a quarter, and you can divide 1.75 by this). To find a quarter, you have to divide by 4, 120/4= 30. Therefore, every 15 seconds, Dorothy can type 30 words. As you've got 105 seconds, divide this by 15, and this gives you 7. Then multiply 30 by 7, and this gives you 210.
Dorothy can type 210 words in 1.75 minutes
Hope this helps :)

120/4=30/4=90

0.75=90

120+90=210 in 1.75 mins

Quinn is flying a kite. The angle of elevation formed by the kite string and the ground is 40°, and the kite string forms a stra
emmasim [6.3K]

The distance between the ground and the kite to the nearest foot is 64 ft.

<h3>What is a right angle triangle?</h3>

A right angle triangle is a triangle that has one of its sides as 90 degrees. The situation forms a right angle triangle.

Hence,

The length of the kite string is the hypotenuse side of the triangle formed.

The height between the ground and the kite is the opposite side of the triangle formed.

Therefore, using trigonometric ratio,

sin 40 = opposite / hypotenuse

sin 40 = h / 100

cross multiply

h = 100 sin 40

h = 100 × 0.64278760968

h = 64.2787609687

h = 64 ft

Therefore, the distance between the ground and the kite to the nearest foot is 64 ft.

4 letters are typed, without repetition. What is the probability that all 4 will be vowels? Write your answer asa percent. Round
Marysya12 [62]

There are 26 letters in the alphabet, 5 are vowels, therefore, the probability of choosing a vowel the first time is:

\frac{5}{26},

and the second time is:

\frac{4}{25}\text{.}

Continuing with this reasoning, we get that the probabilities each time are:

\frac{5}{26},\frac{4}{25},\frac{3}{24},\frac{2}{23}\text{.}

Finally, the probability that you get all vowels is the product of the probabilities:

\frac{1}{2990}\text{.}

Writing the above result as a percentage we get:

0.033\%.

Answer:

0.033\%\text{.}
