Find h. 11 in. h = V[?] in. 14 in Enter
Answer:
[tex]h=8.48\ \text{inches}[/tex]
Step-by-step explanation:
Given that,
Radius of cone, r = 7 inches
Slant height of the cone, l = 11 inches
We need to find the height of the cone. Let the height be h. Using trigonometry to find it as follows :
[tex]h^2+r^2=l^2\\\\h=\sqrt{l^2-r^2}\\\\h=\sqrt{11^2-7^2}\\\\h=8.48\ \text{inches}[/tex]
So, the height of the cone is equal to [tex]8.48\ \text{inches}[/tex].

Pythagorean Theorem is a² + b² = c²
Answer:
x = 5.7
Step-by-step explanation:
Formula:
a² + b² = c²
4² + b² = 7²
16 + b² = 49
b² = 49 - 16
b² = 33
[tex]\sqrt{b^2} =\sqrt{33}[/tex]
b = 5.7

Question 1 (1 point)
Andy bought total of 5 pairs of shoes and soxes. He bought some pairs of shoes and some pairs of soxes.
Set the variabloes as follows:
X = number of pairs of shoes
Y = number of pais of soxes
Which equation shows the total number of shoes and soxes he bought?
2x + 5 y =7
2X + 3 Y = 5
X + Y = 5
7Y - 2x = 5x
Answer:
The equation that shows the total number of shoes and soxes he bought is x+y=5.
Step-by-step explanation:
Given that statement says that Andy bought total of 5 pairs of shoes and soxes this means that the equation would indicate that the sum of the number of pairs of shoes plus the number of pairs of soxes is equal to 5, which can be expressed as:
x+y=5
The other answers are not right because the numbers of pairs of shoes and soxes are multiplied by another number and the statement indicates that the pairs of shoes and soxes is equal to 5.
please write an equation of a line in slope-intercept form with the given slope and y-intercept.

Step-by-step explanation:
-2a = -56
Divide -2 by both sides to isolate the variable.
a = 28
Lin’s mom bikes at a constant speed of 12 miles per hour. Lin walks at a constant speed 1/3 of the speed her mom bikes. What is the slope of each line?

Step-by-step explanation:
The ratio of the sum of two positive integers to their difference is 7:5. If the sum of the two numbers is at most 25, find all possible values for the pair of numbers.
Step-by-step explanation:
Ohk
that means that the sum of the two numbers are 25
so
to get the first number:
[tex] \frac{7}{5} \times 25 = 35[/tex]
And to get the second number:
[tex]\frac{5}{7} \times 25 = \frac{125}{7} [/tex]
