The number of short-sighted patients is 7
The number of long-sighted patients is 5
The number of patients requiring a varifocal lens is 4
Step-by-step explanation:
Stepwise solution-
Throughout the question, only 3 types of patients are mentioned. Hence, it would be safe to assume that he saw/sees these 3 types of patients on Tuesday.
As per the given details-
4 are neither short-sighted patients nor long-sighted patients. Then it means no of varifocal lens patients is 4.
Hence remaining total patients=16-4=12
As given, no of short-sighted patients is 2 more than the number of long-sighted patients.
Let us assume the number of long-sighted patients as “x”
Thus, the number of short-sighted patients would be “x+2”
x+(x+2)=12 (total remaining patients)
2x=10
x=5
Hence, No. of long-sighted outpatients = 5
No. of short-sighted outpatients =7
Answer:
8, 15 and 17 feet respectively
Step-by-step explanation:
Let the shorter leg=l feet
The longer leg of a right triangle is 7 ft longer than the shorter leg, therefore Length of the longer leg=(l+7) feet
The hypotenuse is 9ft longer than the shorter leg. Therefore Length of the hypotenuse=(l+9) feet
Using Pythagoras Theorem
This results into:
l-8=0 or l+4=0
l=8 or -4
Since length cannot be negative, The length l=8 feet
The sides of the rectangle are therefore: 8, 15 and 17 feet respectively
Answer:
Step-by-step explanation:
Chelsea is making a kite in the shape of a triangle. To determine if the triangle is a right triangle, Chelsea completed the following steps.
Step 1:
Find the side lengths of the triangle: 30 inches, 24 inches, 18 inches.
Step 2:
Substitute the values into the Pythagorean theorem: 18 squared + 24 squared = 30 squared.
Step 3:
Combine like terms: (18 + 24) squared = 30 squared.
Step 4:
Evaluate each side: 1764 not-equals 900.
Chelsea says the triangle is not a right triangle. Which best describes the accuracy of her explanation?
The triangle is actually a right triangle. In step 2, Chelsea incorrectly substituted the values into the Pythagorean theorem.
The triangle is not a right triangle, but in step 2 Chelsea incorrectly substituted the values into the Pythagorean theorem.
The triangle is actually a right triangle. In step 3, Chelsea incorrectly rewrote the expression on the left side of the equation.
The triangle is not a right triangle, but in step 3, Chelsea incorrectly rewrote the expression on the left side of the equation.
5 feet and 3 inches, 1 foot=12 inches, 12×5=60+3=63×5=315. so your answer is 315
