Step-by-step explanation:
we can simply get the area of the whole rectangle, that is, the rectangle including the triangle in it, and then get the area of the triangle and subtract it from that of the rectangle, what's leftover, is the part we did not subtract, namely the shaded region.
[tex]\stackrel{\textit{\Large Areas}}{\stackrel{rectangle}{(5)(11)}~~ - ~~\stackrel{triangle}{\cfrac{1}{2}(\stackrel{b}{5})(\stackrel{h}{3})}}\implies 55~~ - ~~\cfrac{15}{2}\implies \cfrac{95}{2}\implies 47.5[/tex]
Find the surface area of the regular pyramid. HELP QUICK!! (Asking again because the commenter DankBoi18 tried to put a virus on my pc)
We will see that the surface area of the triangular pyramid is equal to 170.1 yd^2
How to get the area of the pyramid?Remember that the area of a triangle is equal to:
A = (1/2)*b*h
Where b is the base, and h is the height.
On the triangular pyramid, we have 3 faces with a base of 9 yards and a height of 10 yd, so the area of these 3 faces is:
A = (1/2)*(10 yd)*(9 yd) = 45 yd^2
Also, we can see that the bottom face has a base of 9 yards and a height of 7.8 yards, then its area is:
A' = (1/2)*(9 yd)*(7.8 yd) = 35.1 yd^2
So the total surface area of the pyramid is:
S = 3*A + A' = 3*45 yd^2 + 35.1 yd^2 = 170.1 yd^2

Monica bought a sweater for $48.00. A week later the sweater went on sale for 25% off the original price. If Monica needed to pay 7% sales tax on any purchase, how many dollars would Monica have saved by waiting to buy the sweater on sale?
A. $12.84
B. $12.00
C. $2.52
D. $0.84
Answer:
A $12.84
Step-by-step explanation:
Sweater was originally $48.00 before tax. $48.00 x 7% tax rate (.07) = $3.36 in tax
So the sweater originally would've cost $48.00 + $3.36 = $51.36
The sale price was 25% off the $48.00. $48.00 x 25% (.25) = $12.00
Then you subtract the $12.00 from the $48.00 to get the new price of $36.00
Now that's before tax, so $36.00 x 7% tax rate (.07) = $2.52 in tax
So the sweater would cost on sale $36.00 + $2.52 = $38.52
To figure out how much she would've saved you subtract the sale price & tax from the original price & tax $51.36 - $38.52 = $12.84

Wanwan is 1.69 m tall and is flying a kite. She holds the string of the kite just above her head. The string is 80 m long and makes, x°, between 54° and 55° with the horizontal. Assuming that the string is taut, estimate (2 decimal places) the vertical height of the kite from the ground
Since, the kite is taut the vertical height of the kite from the ground is 66.82 meters
What is a right angle triangle?A right angle triangle has one of its angles as 90 degrees. The sides and angles can be found using trigonometric ratios.
Therefore, the string length is the hypotenuse side. The angle formed is between 54 degree to 55 degrees. Therefore,
sin 54.5 = opposite / hypotenuse
sin 54.5 = h / 80
cross multiply
h = 80 × sin 54.5
h = 80 × 0.81411551835
h = 65.1292414685
Therefore, the vertical height of the ground from the ground is as follows:
vertical height = 65. 13 + 1.69 = 66.82 meters

Write an equation that represents a relationship between these angles. Do NOT use spaces or parentheses.
Answer:
Angle x measures 33.5 degrees.
Step-by-step explanation:
From the given picture, we can note that angle x and the angle of 23 degrees are vertical opposite angles,
Since lines l and m are perperdicular then the angle between then measures 90 degrees, so we have:
[tex]x+23+x=90[/tex]
By collecting similar terms the equation which represents a relation between these angles is:
[tex]2x+23=90[/tex]
Now, by subtracting 23 to both sides, we obtain:
[tex]2x=90-23\\2x=67[/tex]
and by dividing both sides by 2, we get
[tex]x=\frac{67}{2}[/tex]
[tex]x=33.5\\[/tex]
Then angle x measures 33.5 degrees.

Describe any patterns observed between buffer capacities and the concentration of acid or base in each buffer solution.
The higher the concentration of species in solution, the higher the buffer capacity.
What is a buffer?A buffer is a substance that mitigates against changes in acidity and alkalinity. The buffer capacity has to do with the greatest amount of acid/base that the buffer can effectively neutralize without a significant change in the pH of the solution.
We must know that the higher the concentration of species in solution, the higher the buffer capacity of the solution for any given ratio of [HA] to [A⁻] concentration.
