a ladder leans against the side of a house. The angle of elevation of the ladder is 72 degrees, and the top of the ladder is 13 ft above the ground. Find the distance from the bottom of the ladder to the side of the house. Round your answer to the nearest tenth.
I do not know math to save my life.
Answer:
The distance measure is 4.2 ft
Step-by-step explanation:
Here, we want to get the distance from the bottom of the ladder to the side of the house
To get this, we can see that what we have is a right-angled triangle
We need to apply the appropriate trigonometric identity to get the value of what we want
Let us call the measure we want to calculate x
Mathematically;
Tan 72 = 13/x
x = 13/tan 72
x = 4.2 ft

The following are the temperatures in °C for the first 14 days of January:
-6, -2.5, 2, 2.5, -0.5, 5, 10, -3, -7, 3, -1, 7, 1, 4.5
Answer:
x = -5 & x = -2
Step-by-step explanation:
x^2 + 7x +10 = 0 you takeaway 9 as quadratic equations have to equal 0
(x+5)(x+2) = 0 you find 2 numbers that go into 10 that add to make 7 and multiply to make 10
(x+5) = 0 so x =-5 & (x+2) = 0 so x =-2

Answer:
both are reciprocals
Step-by-step explanation:
15.
[tex]\frac{5}{8}\cdot \frac{16}{20}\\\\=\frac{5}{8}\cdot\frac{8}{5}=1[/tex]
so they are reciprocals
17.
[tex]\frac{2}{3}\cdot\frac{12}{18}\\\\=\frac{2}{3}\cdot \frac{3}{2}=1[/tex]
so they are reciprocals
how do you graph 24x−6y=18
Answer:
You will graph a function with the equation being y = 4x - 3, to plot this function read step by step explanation.
Step-by-step explanation:
First we have to find the equation of the line so we do....
24x - 6y = 18
24x = 18 + 6y
6y = 24x - 18
y = 4x - 3
Now that we know the equation we just have to find two point by using this equation and connect them between each other in order to graph the function represented by this equation. For example
For x = 0
y = 4x - 3
y = -3
So we know that there is a point (0, - 3)
For x = 1
y = 4x - 3
y = 4 - 3
y = 1
So we know that there is a a point (1, 1)
Connect the two point and you will get the function graph
Ayliah is 7 years more than 1/2 of Deb's age
use x for the variable
Answer:
The expression [tex]\frac{1}{2}x+7[/tex] can be used to find Ayliah's age.
Step-by-step explanation:
Given statement is:
Ayliah is 7 years more than 1/2 of Deb's age.
Let,
x represent Deb's age.
The expression for Ayliah's age would be;
7 more means addition.
Ayliah's age = [tex]\frac{1}{2}x+7[/tex]
Hence,
The expression [tex]\frac{1}{2}x+7[/tex] can be used to find Ayliah's age.

A recipe uses 5 cups of milk to make 30 servings. If the same amount of milk is used for each serving, how many servings can be made from one quart?
1 gallon = 4 quarts, 1 quart = 2 pints, 1 pint = 2 cups, 1 cup = 8 fluid ounces
Before you try that problem, answer the question below.
How many cups will you need to find the number of servings for?
Answer:
is 6 a choice if so that is the correct answer:)

bc ik
Answer:
For the first part the answer is we will to find the number of servings for 8 cups.
The second and finnal answer is 16 servings
Step-by-step explanation:
2 quarts x 2 = 4 pints x 2 = 8 cups
5 cups per 10 servings unit rate is 1:2 X 8 = 8:16, Therfore 16 servings.

Greatest Common Factor Find the GCF of the given expression: 4x2+28x When providing your answer, do not add any unnecessary spaces. Example: 2(x-1)
Answer:
4x(x+7)
Step-by-step explanation:
Both 4x^2 and 28x are divisible by 4x, which is also the GCF. This means you just have to divide the different parts of the expression to get 4x(x+7)
The Greatest Common Factor of the given expression 4x² + 28x will be 4x.
What is the greatest common factor?Simply said, it is the biggest common element. The highest consistent element in the above example is 15, making 15 the greatest common factor amongst 15, 30, and 105. The biggest chunk of the common factors is called the "Greatest Common Factor" (of two or more numbers).
The expression is given below.
⇒ 4x² + 28x
Take common 4x from both the terms, then we have
⇒ 4x² + 28x
⇒ 4x(x + 7)
The Greatest Common Factor of the given expression 4x² + 28x will be 4x.
More about the greatest common factor link is given below.
