Erin is flying a kite. She knows that 260 feet of the kite

Mathematics
1 answer:
lianna [129]2 years ago
7 0

Answer:

100 ft high

Step-by-step explanation:

We know that Erin, the kite, and her friend create a right triangle since the friend is standing directly under the kite and in front of Erin.  

Thus, we can use the Pythagorean theorem to find the height of the kite.

We can let the side the distance be at represents Erin and the kite's distance be EK (aka the hypotenuse), the side that represents Erin and her friend's distance be EF and the side that represents the kite and the friend's distance be KF.

The theorem says that a^2 + b^2 = c^2, where a and b are the two shortest sides and c is the hypotenuse.

We already have the measure of the hypotenuse (260 ft) and one of the shorter sides (240), so we have:

KF^2+240^2=260^2\\KF^2+57600=67600\\KF^2=10000\\\sqrt{(KF^2=10000)} \\KF=100

On his way to the park, Nathan rides his bike at a rate of 0.50 mile per minute for 3 minutes. He stops to admire an antique car
TiliK225 [7]

Answer and Step-by-step explanation:

Although the question is not complete, but with the context of the question, they are most likely going to ask for the total distance travelled or the total time or speed. So let's work on that.

Total time travelled = (3 + 5 + 4) = 12mins

Total speed travelled = (0.50 + 0.00 + 0.40)miles/min = 0.90mile/min

The 0.00 represents the period he was at rest admiring an antique car. At this moment, he was not moving so his speed is 0.

Total distance travelled = total speed x total time = 0.90miles/min x 12min = 10.8miles

How do you solve 14p−8=22+20p ?
Zanzabum

The value of p is -5

Simply use cross multiplication :

The process of multiplying numbers in the shape of a fraction is called cross multiplication. Cross multiplying, also known as cross multiplication, is the process of multiplying the numerator of one fraction by the denominator of the other fraction on the other side of an equal symbol. Cross multiplication is a method for comparing fractions.

Both fractions with like and unlike parts are multiplied across. When employing the cross-multiplication procedure, we multiply the denominators as well as the numerators when a fraction is dissimilar, or when the denominators of two fractions are not alike.

14p-8=22+20p\\or, 14p-20p=22+8\\or, -6p=30\\or, p=-\frac{30}{6} \\or, p= -5
