find the area of the polygon!
(I don't know why its being deleted im sorry:(
Answers
Answer:
40
Step-by-step explanation:
The given shape is made up of 4 equal right angled triangles.
Formula : -
Area of right angled triangle
= bh / 2
Here,
Base ( b ) = 5
Height ( h ) = 4
Area of each right angled triangle
= bh / 2
= ( 5 x 4 ) / 2
[ 4 = 2 x 2 ]
= ( 5 x 2 x 2 ) / 2
= 5 x 2
= 10
Area of 4 right angled triangles
= 4 x 10
= 40
Note : -
" □ " signify " right angle ".
the sides, based on the tickmarks on the picture, are all equal, so the figure is namely a rhombus with four congruent triangles, in this case each of the four triangles have a base of 4 and a height of 4, so
[tex]\stackrel{\textit{area of the four congruent triangles}}{4\left[ \cfrac{1}{2}(5)(4) \right]\implies 40}[/tex]

Step-by-step explanation:
99 + 60 + 82 + 78 + 93 + 71 + 68 + 86 + 80 + 95 + 72 + 64
Then divide by 12 because that's the total of numbers there are.

Krys walked 1 1/2 hours longer than Glen.
Step-by-step explanation:
Glen walked 3 miles
3 x 1/4 = 3/4
Krys walked 9 miles

Answer:
Angle 74 degrees and 2x are vertical, so they would have to equal each other.
Note: Vertical angles are congruent meaning they measure the same degrees
So we set up the equation;
74 = 2x

Every 14 days, Debbie’s dog eats 4 1/5 pounds of dog food. If Debbie’s dog eats the same amount of food each day, how many pounds does her dog eat per day?
Answers
The amount of food her dog eat per day would be; 0.33 pound.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Given that Debbie’s dog eats 21/5 pounds of dog food every 14 days. Debbie’s dog eats the same amount of food each day.
Therefore,
21/5 pounds of dog food = 14 day
one day = 14 / (21/5 ) pounds of dog food
One day = 14 x 5/ 21
= 10/3
Therefore, the amount of food her dog eat per day would be; 0.33 pound.

What is the distance between (-8, 5) and (6, 5)?
Enter your answer in the box.
___ Units
Answers
Answer:
distance: 14
explanation:
[tex]\sf \sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]
given:
(-8, 5) and (6, 5)solve:
[tex]\sf \rightarrow \sqrt{(5-5)^2+(6--8)^2}[/tex]
[tex]\sf \rightarrow \sqrt{(0)^2+(14)^2}[/tex]
[tex]\sf \rightarrow \sqrt{14^2}[/tex]
[tex]\sf \rightarrow 14[/tex]
Solution:
We know that:
[tex]\text{Distance }=\sqrt{(x_2-x_1)^{2} +(y_2-y_1)^{2}}[/tex]
Finding the coordinates
(x₁,y₁) = (-8,5) = x₁ = -8; y₁ = 5(x₂,y₂) = (6,5) = x₂ = 6; y₂ = 5Substitute the coordinates into the distance formula.
[tex]\text{Distance }=\sqrt{(x_2-x_1)^{2} +(y_2-y_1)^{2}}[/tex]
[tex]\rightarrow \text{Distance }=\sqrt{[(6- (-8)]^{2} +[5-5]^{2}}[/tex]
[tex]\rightarrow \text{Distance }=\sqrt{[(6 + 8]^{2} +[0]^{2}}[/tex]
[tex]\rightarrow \text{Distance }=\sqrt{[14]^{2}[/tex]
[tex]\rightarrow \boxed{\text{Distance }=14 \ \text{units}}[/tex]
What is the slope of the line?
Answers
Answer:
In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. Slope is often denoted by the letter m; there is no clear answer to the question why the letter m is used for slope, but its earliest use in English appears in O'Brien (1844) who wrote the equation of a straight line as "y = mx + b" and it can also be found in Tod hunter (1888) who wrote it as "y = mx + c".
Step-by-step explanation:
Steps for Graphing a Line With a Given Slope
Plot a point on the y-axis. (In the next lesson, Graphing with Slope Intercept Form, you will learn the exact point that needs to be plotted first. For right now, we are only focusing on slope.)Look at the numerator of the slope. Count the rise from the point that you plotted. If the slope is positive, count up and if the slope is negative, count down.
Look at the denominator of the slope. Count the run to the right.
Plot your point.
Repeat the above steps from your second point to plot a third point if you wish.
Draw a straight line through your points.
