Answer:
In order to find out the tangent value of 45 degrees, we need to divide the opposite side to the angle by the adjacent side. Since both the opposite and adjacent sides of this triangle are the same, we can see that tan(45) is equal to 1.
Step-by-step explanation:
In a special right triangle, the base and the perpendicular are the same. Then the tangent of 45° is one.
What is a right-angle triangle?It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function. The Pythagoras is the sum of the square of two sides is equal to the square of the longest side.
We know that in a special right-angle triangle, both acute angles are equal to each other that is 45 degrees.
If the angles are equal then their opposites sides are also equal.
And if two sides are equal to a triangle then the right triangle is an isosceles right triangle.
In an isosceles right triangle, the perpendicular and the base are equal.
P = B
Then the tangent of 45° will be given as
[tex]\rm tan 45^o = 1[/tex]

Using the diagram below, identify the relationship of the pair of angles and find the value of x.
Answer:
The angles are supplementary to each other (their sum is 180 degrees)
x = 62°
Step-by-step explanation:
(2x+10) + 46 = 180
subtract 56 from each side
2x = 124
divide both sides by 2
x = 62°

A local ice cream shop sells root beer floats for $2.75 and milkshakes for $6. One day the shop sold 10 more root beer floats than milkshakes and made $290. How many root beer floats were sold on this day? How many milkshakes?
Answer:
30 milkshakes and 40 root beer floats
Step-by-step explanation:
Set up a system of equation (r is root beer and m is milkshake)
2.75r+6m=290
m+10=r
Substitute
2.75(m+10)+6m=290
2.75m+27.5+6m=290
8.75m=262.5
m=30
Now plug in 30 and solve for r
30+10=40

carlos is planting a vegetable garden. He has 30 carrot seeds, 24 tomato seeds, and 36 lettuce seeds. Each row will have the same number of seeds, but carrots, tomatoes and lettuce will not appear in the same row. If he puts the greatest possible number of seeds in each row how many rows will there be?
Answer: 15
Step-by-step explanation:
The GCF of 30, 24, and 36 is 6. 30 divided by 6 is 5, 24 divided by 6 is 4, and 36 divided by 6 is 6. 5+4+6=15
The number of rows when he puts the greatest possible number of seeds should be considered as 15.
Calculation of the number of rows:Since
He has 30 carrot seeds, 24 tomato seeds, and 36 lettuce seeds.
So
The GCF of 30, 24, and 36 is 6.
Now we have 30 that should be divided by 6 is 5,
And, 24 divided by 6 is 4,
and 36 divided by 6 is 6
So the no of rows should be
= 5+4+6
=15

What is the value of k in the following equation?
2(4k + 5) + 3(3 – 3k) = 25
Answer:
K = - 6
Step-by-step explanation:
Let's solve your equation step-by-step.
2(4k+5)+3(3−3k)=25
Step 1: Simplify both sides of the equation.
2(4k+5)+3(3−3k)=25
(2)(4k)+(2)(5)+(3)(3)+(3)(−3k)=25(Distribute)
8k+10+9+−9k=25
(8k+−9k)+(10+9)=25(Combine Like Terms)
−k+19=25
−k+19=25
Step 2: Subtract 19 from both sides.
−k+19−19=25−19
−k=6
Step 3: Divide both sides by -1.

Determine if the equation y = 15(1.35)* represents exponential growth or decay and justify. Hint: Think about the growth and decay equations.
Answer:sdfghgfdfghnhgfdfgh
Step-by-step explanatsdfghjhgfghjk
====================================================
Explanation:
The equation is in the form y = a*(b)^x
The 'a' is the initial or starting value. In this case, a = 15.
The b is the base of the exponent which is tied to growth or decay. If 0 < b < 1, then we have decay. If b > 1, then we have growth.
Since b = 1.35, and 1.35 > 1, this means b > 1 and the given equation represents exponential growth.
Solving 1+r = 1.35 leads to r = 0.35. This means the growth rate is 35%

If Kelly walks 2 miles in 80 minutes, then Kelly will walk how far in 110 minutes if she walks at the same
speed the whole time? If necessary, round your answer to the nearest tenth of a mile.
Answer:
2.75 miles
Step-by-step explanation:
Given that,
Kelly walks 2 miles in 80 minutes.
We need to find how far Kelly will walk in 110 minutes if she walks at the same speed the whole time.
Speed = distance/time
So,
[tex]\dfrac{2}{80}=\dfrac{d}{110}\\\\d=\dfrac{2\times 110}{80}\\\\d=2.75\ \text{miles}[/tex]
Hence, she will walk 2.75 miles.
