Answer:
0.68 miles
Step-by-step explanation:
Let's say that the height of the mountain is h
The distance between the mountain and the car, after moving 23 miles closer to the mountain, will be x (let's pose it as x for now)
tan(1.5°) = opposite/adjacent = h/23 + a
=> h = (23 + a)tan(1.5°) ---- (1)
tan(13°) = h/a
=> h = a(tan(13°)) ---- (2)
Now since h is common among the two equations, we can equate them;
[tex]\left(23+a\right)\tan \left(1.5^{\circ \:}\right)=a\left(\tan \left(13^{\circ \:}\right)\right),\\23\tan \left(1.5^{\circ \:}\right)+\tan \left(1.5^{\circ \:}\right)a=\tan \left(13^{\circ \:}\right)a,\\\\\tan \left(1.5^{\circ \:}\right)a-\tan \left(13^{\circ \:}\right)a=-23\tan \left(1.5^{\circ \:}\right),\\\left(\tan \left(1.5^{\circ \:}\right)-\tan \left(13^{\circ \:}\right)\right)a=-23\tan \left(1.5^{\circ \:}\right),\\\\[/tex]
[tex]a=\frac{23\tan \left(1.5^{\circ \:}\right)}{\tan \left(13^{\circ \:}\right)-\tan \left(1.5^{\circ \:}\right)} = 2.94249...[/tex]
[tex]h = 2.94249tan\left(13^{\circ }\right) = 0.67932\dots[/tex]
The height of the mountain ≈ 0.68 miles

At the beginning of the day, it was -14 degrees. Throughout the day, the temperature increased 16 degrees. What was the temperature (in degrees) at the end of the day? At the beginning of the day, it was -14 degrees. Throughout the day, the temperature increased 16 degrees. What was the temperature (in degrees) at the end of the day?
Answer:
The temperature at the end of the day is 2 degrees
Step-by-step explanation:
Here, we are interested in calculating the temperature at the end of the day.
In the question, we are told that at the beginning of the day, temperature was -14 degrees.
But throughout the day, the temperature increased by 16 degrees;
Thus, the temperature at the end of the day = -14 degrees + 16 degrees = 2 degrees
The area of a blackboard is 1 1⁄3 square yards. A poster’s area is 8⁄9 square yards. Find the unit rate and explain, in words, what the unit rate means in the context of this problem. Is there more than one unit rate that can be calculated? How do you know?
Answer:

40 calls in 20 hours=__calls in 10 hours
I have my answer my mom said its right my dad said its wrong what do u smart people think
Answer: 20 calls
Explanation: This is because since 40 is half of 20, you would need to divide by 2 to get 10. If you convert the division to multiplication, 10 * 2 = 20. So, the answer would be 20 calls.

Write a function that makes the following true: f(5) = 10
*i got f(x)= 2x which is correct*
Solve your function when
f(x) = 5. *I need the answer for this*
Answer as a fraction: x = 5/2
Answer in decimal form: x = 2.5
=====================================================
Explanation:
Replace f(x) with 5
So we go from f(x) = 2x to 5 = 2x
Now isolate x. We do so by dividing both sides by 2 (this undoes the multiplication of 2 on x)
So we get
5 = 2x
5/2 = 2x/2 ... divide both sides by 2
5/2 = x
x = 5/2
x = 2.5

Answer:
[tex]\frac{114}{13}[/tex] or 8 [tex]\frac{10}{13}[/tex]
Step-by-step explanation:
1) Convert the mixed numbers to improper fractions
3+ [tex]\frac{15}{2}[/tex] ÷ [tex]\frac{13}{10}[/tex]
2) To divide by a fraction, multiply by the reciprocal of that fraction
3+[tex]\frac{15}{2}[/tex] × [tex]\frac{10}{3}[/tex]
3) Reduce the numbers with the greatest common factor 2
3 + 15 ×[tex]\frac{5}{13}[/tex]
4) Calculate the product
3 + [tex]\frac{75}{13}[/tex]
5) Calculate the sum
[tex]\frac{114}{13}[/tex] = 8 [tex]\frac{10}{13}[/tex]
A photo frame in the shape of a quadrilateral has one diagonal longer than the other. Is it a Rectangle? Why
or why not?
Find the value of ‘x’ from the given
Answer:
80°Step-by-step explanation:
A rectangle has same opposite sides and 4 right angles as property of a rectangle.
The photo frame has different diagonal lengths
It makes opposite sides different, therefore it is not a rectangle
Given angles (x - 20) and (x + 40) are consecutive interior angles which add up to 180°
x - 20° + x + 40° = 180°2x + 20° = 180°2x = 160°x = 80°Simplify the expression.
−23(12c−9)+14c =
The simplification of the expression would be equal to -262c +207.
An equation is defined as an expression which shows the relationship between two or more numbers, variables, and a mathematical equation is a statement with two equal sides and an equal sign in between.
We are given the expression as;
−23(12c−9)+14c =
Now ;
-23(12c) -23 * -9 + 14c
Now Apply the distributive property;
2. -276c -23 * -9 + 14c
Then Multiply 12 by -23
-276c + 207 + 14c
Add -276c and 14c
-262c +207
The answer is -262c +207

Selena made pancakes for an all day breakfast fundraiser event she made 132 pancakes in 4 hours Selena used 44 cups of pancake batter to make 132 pancakes if Selena continues to make the same number of pancakes per cup of batter how many cups of batter will Selena use to make an additional 264 pancakes
Answer:
88 cups of batter
Step-by-step explanation:
We are told from the the question: Selena used:
132 pancakes was made from = 44 cups of pancake batter
how many cups of batter will Selena use to make an additional 264 pancakes?
132 pancakes = 44 cups of pancake batter
264 pancakes = ??
Cross Multiply
= 264 × 44/132
= 11616 / 132
= 88 cups of pancake batter.
Therefore, selena would be needing 8( cups of pancake butter to make an additional 264 pancakes.
Answer:
