The measure of the angle in the triangle is of 85º.
How to find the measure of the angle?In the context of this problem, the measure of the angle is found using the ruler in the given image.
Due to the position that the triangle opens, from left to right, we have to read the angles from the bottom line.
The measures are listed in intervals of 10º, however each trace represents one degree.
The angle of the illustrated triangle is positioned at the 5th trace between 80º and 90º, hence the measure of the angle in the triangle is calculated as follows:
80º + 5º = 85º.
This is because each trace represents one degree, and the angle is at the 5th trace between 80º and 90º.

Answers
Answer:
y = 0
Step-by-step explanation:
The function has a horizontal asymptote at y = 0 where y is the value of the car
[tex]\text{Since the equation for the value of the car is }[/tex] [tex]23000(1-0.15)^t[/tex]
As [tex]t \rightarrow \infty, \text{the term } (1-0.15)^t \rightarrow 0 \\[/tex]
This is because the term (1-0.15) is < 1 and a nˣ approaches 0 as x → ∞ since the values get smaller and smaller with increasing powers of x
So the equation for the horizontal asymptote is y = 0

(g o f)(-8) = 36
For f(x) = 2x + 12 and g(x) = 2x² + 2x + 12 the value of (g o f)(-8) is 36.
Solution:Given that f(x) = 2x + 12, g(x) = 2x² + 2x + 12.
to locate (g o f) (-8),
To find (g o f)(-8), we must first find g(f(x)) and then substitute x = -8.
Find g(f(x)) by substituting f(x) into g. (x)
= g(f(x)) = 2( 2x +12)² + 2( 2x + 12) + 12
x = -8 so,
g( f( - 8) ) = 2( 2(-8) +12)² + 2( 2(-8) + 12) + 12
g( f( - 8) ) = 2( -16 +12)² + 2( -16 + 12) + 12
g( f( - 8) ) = 2(-4)² + 2( -4 ) + 12
g( f( - 8) ) = 2 x 16 -8 + 12
g( f( - 8) ) = 32 - 8 + 12
g( f( - 8) ) = 36

Answer: $31.50 for the four brushes after using the coupon
Step-by-step explanation:
$10.50 (Amount for EACH brush) * 0.75 (coupon 25% off) = $7.875 (Amount for each after coupon)
$7.875* 4 brushes = $31.5

We will investigate how to determine one of the indicator dimensions of a regular figure.
We have a rectangular fish tank which can be modeled as a cuboid. The indicator lengths of a cuboid or a rectangular fish tank are as such:
[tex]\begin{gathered} \text{Length ( L ) } \\ \text{Width ( w ) = 8.8 cm} \\ \text{Height ( h ) = 9 cm} \end{gathered}[/tex]One of the indicator lengths of the rectangular fish tank Length ( L ) is unknown. Howver, we are given the total amount of water that the fish tank can withold as follows:
[tex]\text{Water in fish tank = 950.4 mL}[/tex]We will use the conversion factor between milliLiters and centimeter cube as follows:
[tex]1\text{ mL }\to1cm^3[/tex]Therefore,
[tex]950.4\text{ mL }\to950.4cm^3[/tex]The amount of water a fish tank can hold is equivalent to the volume of the fish tank. We have modeled our rectangular fish tank as a cuboid. The volume ( V ) of a cuboid can be expressed in terms of its indicator dimensions as follows:
[tex]V\text{ = L}\cdot w\cdot h[/tex]We can use the above volume expression to determine one off our missing indicator dimension of length ( L ). We plug in the respective quantities and evaluate:
[tex]\begin{gathered} 950.4\text{ = L}\cdot(8.8\text{ ) }\cdot\text{ ( 9 )} \\ \\ L\text{ = }\frac{950.4}{8.8\cdot9}\text{ = }\frac{950.4}{79.2} \\ \\ L\text{ = 12 cm} \end{gathered}[/tex]Therefore, the length ( L ) of the fish tank must be:

1) We know that the sum of the interior angles within a triangle is 180º
So we can state that :
∠X = 80º , ∠V=32º and ∠W = 180º-(80+32), ∠W=68º
2) The area of a triangle can be found by the Heron formula, but before that, we need to find out the other legs. Let's sketch this and use the Law of Sines:
The Law of Sines:
[tex]\begin{gathered} \frac{v}{\sin(V)}=\frac{w}{\sin(W)}=\frac{x}{\sin(X)} \\ \frac{v}{\sin(32)}=\frac{680}{\sin(68)} \\ 680\text{ sin(32) = vsin(68)} \\ \frac{680\text{ }\sin(32_{}}{\sin(68)}=v \\ v\text{ =}388.65 \\ \\ \end{gathered}[/tex]Now let's proceed to find the length of side x:
[tex]\begin{gathered} \frac{w}{\sin(W)}=\frac{x}{\sin(X)} \\ \frac{680}{\sin(68)}=\frac{x}{\sin (80)} \\ x\sin (68)=680\cdot\sin (80) \\ x=\frac{680\cdot\sin (80)}{\sin (68)} \\ x\approx722.26 \end{gathered}[/tex]Now we can add the three sides and find out the Perimeter:
2p: 722.26 +388.65 +680
2p=1790.91
And the semi perimeter is p =2p/2, p =895.455.
2.2) Finally we can find out the area using the Heron Formula:
[tex]\begin{gathered} A=\sqrt[]{p(p-v)(p-w)(p-x)} \\ A=\sqrt[]{895.455(895.455-388.65)(895.455-722.455)(895.455-680)} \\ A=130059.9757\approx130060 \end{gathered}[/tex]3) Hence, the area is 130,060 cm²

Number of 1 point shot = 0
Number of 3 and 2 points shots = 38
Step 2: Write out the system of equations

[tex]undefined[/tex]Abdul, Beckie, Cynthia and Douglas are making pancakes according to the recipe below:Which person can make the most pancakes?BeckieAbdulCynthiaDouglas
Answers
To make 12 pancakes we need 100 g flour, 2 eggs, 300 ml milk
Abdul has 175 g flour, 4 eggs and 500 g milk
The ration between Abdul's amount of each ingredient and the total needed to make 12 pancakes is: (175/100) = 1.75 flour, (4/2) = 2 eggs, (500/300) = 1.67 milk.
So, the total amount of pancakes that Abdul can make is determined by the amount of the less abundant ingredient (milk): 1.67*12 = 20 pancakes
Doing the same steps for Beckie, we got that her less abundant ingredient is milk, with a ratio of 400/300 = 1.33. Then, she can make 1.33*12 = 16 pancakes.
For Cynthia, her less abundant ingredient is flour, with a ratio of 150/100 1.5. Then, she can make 1.5*12 = 18 pancakes.
And for Douglas, his less avundant ingredient is egg, with a ratio of 3/2 = 1.5. Then, he can make 1.,5*12 = 18 pancakes.
Therefore, Abdul is the one who can make the most pancakes
