Distance = \sqrt{ (a-0)^{2} + (0-5)^{2} }

Answer:

Expression that represents distance between points (a,0) and (0,5) is:

\sqrt{a^2+5^2}

Step-by-step explanation:

The distance between points (x1,y1) and (x2,y2) is given by:

\sqrt{(x2-x1)^2+(y2-y1)^2}

Here, (x1,y1)=(a,0) and (x2,y2)=(0,5)

\sqrt{(0-a)^2+(5-0)^2}

=  \sqrt{a^2+5^2}

Hence, expression that represents distance between points (a,0) and (0,5) is:

\sqrt{a^2+5^2}

Using the same triangle as above, calculate the area of the triangle. You must show TWO methods for calculating the area of the
Damm [24]

Answer:

Step-by-step explanation:

Area of a triangle is 1/2 * b * h

b = base, the one labeled b on the diagram

h = height, the dotted line in the middle

so, you do pythagorean theorem with a and b to find the dotted line

a² + b² = h² (h is for height)

h = \sqrt{a^{2} +b^{2}}

Then, you just plug in the numbers from question 3 to find h and then you do

1/2 * b * h

Carlos is packing bags for treats at a party. Every bag has exactly the same amount of treats in it. Carlos has 25 granola bars
Advocard [28]

Answer:

5 bags

Step-by-step explanation:

Given

Granola\ Bars = 25

Popcorn\ Balls = 35

Required

Determine the greatest number of bags

This question illustrates greatest common factor (GCF).

The number of bags will be solved by getting the GCF of 25 and 35.

This is shown below:

25 = 1 * 5 * 5

35 = 1 * 5 * 7

GCF = 1 * 5

GCF = 5

Hence, Carlos will need 5 bags
