Find an equation of the line passing through the point (5,4) and parallel to the line whose equation is 2x+y=3
Answer:
Step-by-step explanation:
Use the point-slope formula.
y - y_1 = m(x - x_1) you have : x_1 =5 and y_1 =4
m the slope m= -2 (same slope for the line : 2x+y=3 because this lines are parallel and you can write y=-2x+3
an equation for this line is : y-4 = -2(x-5)
Final answer:
The equation of the line parallel to 2x + y = 3 and passing through the point (5, 4) is y = -2x + 14.
Explanation:
To find the equation of a line that is parallel to the given line 2x + y = 3 and passes through the point (5, 4), we first need to put the given line into slope-intercept form (y = mx + b), where m represents the slope and b the y-intercept. For the equation 2x + y = 3, we solve for y to get y = -2x + 3, which shows that the slope (m) is -2. Since parallel lines have the same slope, our new line will also have a slope of -2.
Using the point-slope form (y - y1 = m(x - x1)), where (x1, y1) is the point (5, 4) and m is -2, we get y - 4 = -2(x - 5). Simplifying this, y - 4 = -2x + 10, which leads to y = -2x + 14 as the equation of the line passing through (5, 4) and parallel to 2x + y = 3.

5 ft
8 ft
32 it
At the same time of day, a tree's shadow is 32 feet long. What is the height of the tree?
Answer:
20 ft
Step-by-step explanation:
The 2 triangles are similar, thus the ratios of corresponding sides are equal.
let h be the height of the tree, then
[tex]\frac{h}{5}[/tex] = [tex]\frac{32}{8}[/tex] = 4 ( multiply both sides by 5 )
h = 20
The height of the tree is 20 ft
The height of the tree that both triangles are similar to is 20 feet.
What is symmetry?If two figures look an exact shape but their size could be small or big then both figures are called similar figures.
When anything has identical pieces facing one another or revolving around an axis, it is said to be symmetrical.
As per the given two triangles,
Let's say the height of the tree is h.
By similar triangle property
h/32 = 5/8
h = (5/8)32
h = 5 x 4 = 20 feet
Hence "The height of the tree that both triangles are similar to is 20 feet".

The width of a rectangle is 1 units less than the length. The area of the rectangle is 56
units. What is the width, in
Units
Answer:
Width = 7 units
Step-by-step explanation:
Length = x units
Width = (x -1) units
Area = 56 square units
length * width = 56
x * (x - 1) = 56
x*x - x*1 = 56
x² - x - 56 = 0
x² -8x + 7x - 7*8 = 0
x(x - 8) + 7(x - 8) = 0
(x - 8)(x + 7) = 0
Here, (x +7) is ignored because measurement will not in negative.
x - 8 = 0
x = 8
Length = 8 units
Width = 8-1 = 7 units

(-6, 5), (-5, 0), (-4, -3), (-3, -4), (-2, -3), (-1, 0), (0, 5).
Although on observation, the minimum point of y occurs at (-3, -4), we can also confirm through the function.
The x-intercept of the parabola are -5 and -1.
x=-5 or x=-1
x+5=0 or x+1=0

How many angles are alternate interior angles with angle 9?
Brainliest for whoever answers first!!!!!!
Answer:
Angle 7 and angle 15
Step-by-step explanation:
Alternate Interior Angles are a pair of angles on the inner side of each of those two lines but on opposite sides of the transversal.Alternate interior angles with angle 9 are:
Transversal s, parallel lines are t and u,
Angle 9 is in pair with angle 7Transversal u, parallel lines are s and r,
Angle 9 is in pair with angle 15If angle 9 is an interior angle within a pair of parallel lines cut by a transversal, then there would be one alternate interior angle to angle 9. The alternate interior angles are those inside the lines and on opposite sides of the transversal.
Explanation:In a pair of parallel lines cut by a transversal, the alternate interior angles are those angles that are inside the pair of lines and on opposite sides of the transversal. The alternate interior angles are equal when the lines are parallel. From your question, it's not clear which lines are parallel and where angle 9 is located.
Let's assume that angle 9 is one of the interior angles created by the transversal on a pair of parallel lines. In that case, there would be one angle that is an alternate interior angle to angle 9. So without more information, we can only say that there is one alternate interior angle to angle 9.

C. by hiring a local agent or broker who is familiar with her needs
and
E. by registering on the website of a national insurance company
Step-by-step explanation:
Just got this right on Plato :)
To independently obtain additional insurance, Natasha has two main options: hiring a local insurance agent or broker for personalized service, or registering on the website of a national insurance company for convenience and direct-purchase options.
Explanation:Natasha can accomplish her goal of obtaining additional insurance coverage independently from her employer by following two main paths:
C. by hiring a local agent or broker who is familiar with her needs, orE. by registering on the website of a national insurance company.By consulting a local insurance agent or broker, she can receive personalized advice and find coverage that fits her specific situation.
On the other hand, registering on the website of a national insurance company allows her the convenience to compare different plans and sign up for insurance that she can directly purchase.

Ashley use 1/5 cup of winegar in her salad dressing recipe. How much
vinegar would Ashley use to make 2/3 of a recipe? *
Answer:
I think the answer is 2/15 but I'm not a hundred percent sure
Ashley would use [tex]\(\frac{2}{15}\)[/tex] cup of vinegar to make [tex]\(2/3\)[/tex] of her salad dressing recipe.
To find out how much vinegar Ashley would use to make 2/3 of her salad dressing recipe, we need to calculate the amount of vinegar used in the full recipe and then scale it down to 2/3 of that amount.
In the full recipe, Ashley uses 1/5 cup of vinegar. To make 2/3 of the recipe, we multiply the amount of vinegar needed for the full recipe by 2/3:
[tex]\[ \text{Vinegar for } \frac{2}{3} \text{ of the recipe} = \frac{1}{5} \text{ cup} \times \frac{2}{3} \] \[ \text{Vinegar for } \frac{2}{3} \text{ of the recipe} = \frac{1}{5} \times \frac{2}{3} \text{ cup} \] \[ \text{Vinegar for } \frac{2}{3} \text{ of the recipe} = \frac{1 \times 2}{5 \times 3} \text{ cup} \] \[ \text{Vinegar for } \frac{2}{3} \text{ of the recipe} = \frac{2}{15} \text{ cup} \][/tex]
So, Ashley would use [tex]\(\frac{2}{15}\)[/tex] cup of vinegar to make 2/3 of her salad dressing recipe. Simplifying [tex]\(\frac{2}{15}\)[/tex] gives us [tex]\(\frac{2}{15} = \frac{2 \div 1}{15 \div 1} = \frac{2}{15}\)[/tex], which is already in its simplest form. Thus, the final answer remains [tex]\(\frac{2}{15}\)[/tex] cup of vinegar.

Monica sells lemonade over the summer and uses conical paper cups to serve the lemonade. Each cupis ퟖcentimeters in diameter and ퟏퟏcentimeters tall. She starts with a ퟏퟎ-gallon container (one gallon is equivalent to ퟑퟕퟖퟓ풄풎ퟑ)
Answer:
Part A Answer = 206
Part B Answer= 5
Step-by-step explanation:
Part A Explanation:
The formula for volume of a cone is V=(1/3) pi*r^2 h
So then you plug in. V= 1/3 pi (4)^2(11)
You get the radius by dividing the diameter by 2
When you multiply it all it becomes 184.31cm^3 (Save this for later on in this Part A question)
Now we have to find the Volume of the cooler. That would be: 10*3785=37850 Since there were 10 gallons and each gallon is 3785 cm^3 you multiply them together.
Then you divide the volume of the cooler by the volume of the cone cup: 37,850/184.31=205.36 but since you cannot have 205.36th of a cup you need to get another one since 205 would not be enough giving us a total of 206 cups.
Part B explanation: Since there are 50 cups per package you would have to divide 206 by 50. 206/50=4.12 but again since you cannot buy 4.12 of a package you need to buy 5 packages for it to be enough.

Answer:
Step-by-step explanation:
Given
Length of the minute hand = 14 inches
Time = 1 hour
Required
Length of the path traced in 1 hour
For, the minute hand to have completer an hour, this means it completes a cycle;
1 cycle is equivalent to 1 complete rotation;
So, basically the question implies that; the circumference of the complete rotation be solved for;
To solve for this; we make use of the circumference formula;
[tex]C = 2\pi r[/tex]
Where
C represents the circumference
r represents the radius or the length of the minute hand
[tex]\pi = \frac{22}{7}[/tex] --- This is given from the question;
By substitution, we have
[tex]C = 2 * \frac{22}{7} * 14[/tex]
[tex]C = \frac{2 * 22 * 14}{7}[/tex]
[tex]C = \frac{616}{7}[/tex]
[tex]C = 88 inches[/tex]
Hence, the length of the path traced is 88 inches

A company wants to increase the 10% peroxide content of its product by adding pure peroxide (100% peroxide). If x liters of pure peroxide are added to 100 liters of its 10% solution, the concentration, C, of the new mixture is given by the formula below. How many liters of pure peroxide should be added to produce a new product that is 70% peroxide? C= (x + 0.1(100))/(x +100)
Answer:
200 liters.
Step-by-step explanation:
To solve this, let's first set C in our equation to .7, since that is the concentration we are aiming for.
.7= [tex]\frac{(x+0.1(100))}{x+100}[/tex]
Next, we can simply this equation further:
.7= [tex]\frac{(x+10)}{x+100}[/tex]
We can multiply both sides by the denominator, resulting in:
.7x+70= x+10
Finally, continue simplifying to solve for x:
60= .3x
x= 200 liters.
