The points (14,22) and (49,77) form a proportional relationship. Find the slope of the line through
the points. Then use the slope to graph the line.
The slope is
Answer:
Step-by-step explanation:
The slope is the change of y over the change of x.
the change of y:77-22=55
the change of x:49-14=35
55/35 simplified is 11/7

Answer:
Measure of EF: 1.98
Measure of AB: 6.16
Measure of HI: 12.2
Step-by-step explanation:
Trick I learned that's very helpful when solving these problems: SOH (Sine, Opposite, Hypotenuse)- CAH (Cosine, Adjacent, Hypotenuse)- TOA (Tangent, Opposite, Adjacent)
MEASURE OF EF
you're starting with angle D which is 26 degrees. You have the measure of the Hypotenuse (DF) and you're trying to find the measure of EF (the segment opposite the angle) so you would use Sine
to do the equation, i'm going to use x in place of EF. 0.44 = sin(26)
Formula: sin(angle) = (opposite)/(hypotenuse)
Equation:
0.44 = x/4.5 <----------- multiply by 4.5 to get x by itself
4.5*0.44 = x <---------- 4.5 times 0.44
1.98= x <----------------answer
MEASURE OF AB
trying to find hypotenuse and you already have the adjacent angle so you would use cosine. Using y in place of AB. 0.616 = sin(52)
cos(angle) = (adjacent)/(hypotenuse)
cos(52) = 10/y <------ divide by y
y*0.616 = 10 <------------ divide by 0.616
y = 10/0.616 <----------- next you'll divide 10 by 0.616
y = 6.16 <-----------answer
MEASURE OF HI
trying to find adjacent, already have opposite so you would use tangent. tan(42) = 0.90. using z in place of HI
tan(angle) = (opposite)/(adjacent)
tan(42) = 11/z <------------ multiply z on both sides
z*0.90 = 11 <--------- divide by 0.90 to get z by itself
z = 11/0.90 <-------- divide 11 by 0.90
z = 12.2
For Anthony’s birthday, his mother is making cupcakes for his 12 friends at his daycare. The recipe calls for 3 1/3 cups of flour. This recipe makes 2 1/2 dozen cupcakes. Anthony’s mother has only 1 cup of flour. Is there enough flour for each of his friends to get a cupcake
Answer:
No, there is no enough flour for each of his friends to get a cupcake
Step-by-step explanation:
Let us use the ratio method to solve the question
∵ This recipe makes 2[tex]\frac{1}{2}[/tex] dozen cupcakes
∵ Each dozen contain 12 cupcakes
∴ The number of cupcakes can the recipe make = 2[tex]\frac{1}{2}[/tex] × 12
∴ The number of cupcakes can the recipe make = 30 cupcakes
∵ The recipe calls for 3[tex]\frac{1}{3}[/tex] cups of flour
→ That means 3[tex]\frac{1}{3}[/tex] cups of flour can make 30 cupcakes
∴ 3[tex]\frac{1}{3}[/tex] cups of flour makes 30 cupcakes
∵ Anthony’s mother has only 1 cup of flour
→ By using the ratio method
→ flour : cupcake
→ 3[tex]\frac{1}{3}[/tex] : 30
→ 1 : x
→ By using cross multiplication
∵ 3[tex]\frac{1}{3}[/tex] × x = 1 × 30
∴ 3[tex]\frac{1}{3}[/tex] x = 30
→ Divide both sides by 3[tex]\frac{1}{3}[/tex]
∴ x = 9
∵ x represents the number of cupcakes
∴ Anthony’s mother can make 9 cupcakes with 1 cup of flour
∵ Anthony has 12 friends at his daycare
∵ The number of the cupcakes = 9
∴ The number of cupcakes is not enough for each of his friends to
get a cupcake

Why is it important to have a plan for proof before writing the proof? Explain why it helps and what can happen without a plan for proof. *WILL GIVE 15 POINTS TO BEST ANSWER*
Answer:
The reason why it helps to have a plan of proof before writing the proof is that the proof plan is the collection of recollected knowledge about the question that will ensure that the required proof is achieved
The proof plan is equivalent to a virtual construction, consisting of the required parts and how the parts fit together, that obeys or satisfies the actual conditions when the written, step by step on paper
Without a proof plan, the required parts of the proof and therefore how the parts will fit to provide the proof will be absent as well as the non required parts written down to provide a proof without a plan can be confounding

Before enrolling in a typing course, Maria could type 35 words per minute. At the end of the course, she could type 77 words per minute. Find the percent of increase in her typing rate
Given:
Initial speed of typing = 35 words per minute
At the end of the course her typing speed = 77 words per minute
To find:
The percent of increase in her typing rate.
Solution:
We know that,
[tex]\text{Percent of increase in her typing rate}=\dfrac{\text{New speed - initial speed}}{\text{Initial speed}}\times 100[/tex]
[tex]\text{Percent of increase in her typing rate}=\dfrac{77-35}{35}\times 100[/tex]
[tex]\text{Percent of increase in her typing rate}=\dfrac{42}{35}\times 100[/tex]
[tex]\text{Percent of increase in her typing rate}=120\%[/tex]
Therefore, her typing rate is increased by 120%.

Perpendicular slopes always multiply to -1. This is assuming neither line is vertical.
A salesperson's commission rate is 4%. What is the commission from the sale of $37,000 worth of furnaces? Use pencil and paper. Suppose sales would double. What would be true about the commission?
Answer:
The earnings will doubleStep-by-step explanation:
Step one:
given data
we are told that the sales person's earnings is 4% of the sales made.
given that the sales made is $37,000 worth of furnaces.
Step two:
we want to find 4% of $37,000
=4/100*37000
=0.04*37000
=1480
hence for $37,000 the earning will be $1480.
Now suppose sales is doubled that is 37000*2= 74000
we want to find 4% of $74,000
=4/100*74000
=0.04*74000
=2960.
the earnings is $2960.
So if sales doubles the earnings will double

Answer:
The answer is letter D.
If we solve the given function when the functions are f(x)=[tex]\sqrt{6x}[/tex] and g(x)=[tex]\sqrt{24x}[/tex] then we will be able to find it equal to 12x.
What is a function?
A function is a relation in which each element of x is having a value in the y element. It is written in the form of f(x).
How to solve two functions?f(x)=[tex]\sqrt{6x}[/tex] and g(x)=[tex]\sqrt{24x}[/tex]
(f.g)x=f(x)*g(x)
=[tex]\sqrt{6x} *\sqrt{24x}[/tex]
=[tex]\sqrt{6x}*2\sqrt{6x}[/tex]
=2*6x
=12x

Elise doesn't like sorbit, so she omits that ingredient and adds 5 percent to each of the other ingredients. How many cups of punch will she have if she uses 6 cups of orange juice?
Answer: 20
Step-by-step explanation:
From the question, to make the punch recipe, the following are needed:
Ginger Ale - 40%
Orange Juice - 25%
Pineapple juice - 20%
Sorbet - 15%
Since we are told that Elise doesn't like sorbit, so she omits that ingredient and adds 5 percent to each of the other ingredients. The the new percent will be:
Ginger Ale - 40% + 5% = 45%
Orange Juice - 25% + 5% = 30%
Pineapple juice - 20% + 5% = 25%
Sorbet - 15% - 15% = 0
To get the total cups of punch that'll be used, let it be represented by y. Therefore,
30% of y = 6
30/100 × y = 6
0.3 × y = 6
0.3y = 6
y = 6/0.3
y = 20
Therefore, she'll have 20 cups of punch.

OK SO I SOLVED ALL OF THIS: It costs a company $20 per box to make pocket-sized stuffed animals. The company also has a fixed manufacturing cost of $2300. The owners are trying to calculate their cost for making boxes of animals. --Function Rule: c(x) = 20b + 2300.
BUT I NEED HELP WITH THIS!!! Use your function rule to find out how many boxes of stuffed animals can the company manufacture for $5000? SHOW WORK.
basically just show the work to find out what "b" would have to be in order for the
answer to be $5,000 i would appreciate it so much :) please help this is due today :(
Answer:
The company can manufacture 135 boxes of stuffed animals for $5000
Step-by-step explanation:
To find b, substitute $5000 for c(x), so
5000 = 20b + 2300Then subtract 2300 from both sides of the equation, so
5000 (-2300) = 20b + 2300 (-2300)2700 = 20bFinally divide both sides of the equation by 20, so
2700/20 = 20b/20135 = bTo check your answer substitute 135 in as b...
c(x) = 20(135) + 2300c(x) = 5000ANSWER ASAP FOR BRAINLIESTT
