Find the measures of the angles of a triangle in which one angle is 70°& the other two are in the ratio 3:8.
Answer:
30° ; 80°
Step-by-step explanation:
Given that :
One angle of a certain triangle = 70°
The other two angles are in the ratio 3 : 8
Recall :
Sum of angles in a triangle = 180°
Number of angles in a triangle = 3
Hence,
Sum of the other two angles + 70 = 180
Hence, sum of the other two angles = (180 - 70)°
Sum of other two angles = 110°
The angle is in the ratio 3:8
Hence,
(3 / (3 +8)) * 110
= 3/11 * 110
= 330 / 11
= 30°
(8 / (3 +8)) * 110
= 8/11 * 110
= 880 / 11
= 80°
Hence ; 30° ; 80°
At Irtaza's Deli he is selling 7 oranges for $5.99 and Brianna's Food Mart is selling them 10 for $8.99. Where would you go shopping and why?
Answer:
At Irtaza's Deli
Step-by-step explanation:
For this you should find the unit price and whichever is less is where you should go.
(1) Irtaza Deli:
First I would round the 5.99 to 6 then we'll do 6 divided by 7.
[tex]\frac{6}{7}=.8571428571=.86[/tex]
(2) Brianna's Food Mart:
First I would round the 8.99 to 9 then we'll do 9 divided by 10.
[tex]\frac{9}{10}=.9[/tex]
Now let's compare:
So the first store sells oranges for $.86 and the second store sells them for $.90. I don't know about you but I would go to the first store they would be much more cheaper.

What is the equation, in standard form, of a parabola that models the values in the table?
y=4x^2+5x-6y=4x2+5x−6
:
Given points are :
x = -2 0 4
y=f(x) = 0 -6 78
We have to model the parabola with the help of these points
Solution:
We consider a standard equation of parabola y= ax^2+bx+cy=ax2+bx+c
now, we put the points in the equation we get,
at (-2,0) is 4a-2b+c=0
at (0,-6) is c=-6
at (4,78) is 78= 16a+4b+c
now, solving these equation we get, a= 4 , b= 5 , c= -6
so the equation formed with these points is y=4x^2+5x-6y=4x2+5x−6
we can see this in the graph attached.

Every American generates approximately 2 kg of waste every day. The amount of compostable waste that could be generated by one individual in a week would be closest to
Answer:
8.4 kg
Step-by-step explanation:
First, find how much waste is created in a week:
Multiply 2 by 7, since they create 2 kg of waste each day:
2(7)
= 14 kg
Then, find 60% of this:
Multiply 14 by 0.6:
14(0.6)
= 8.4
So, the amount of compostable waste created by 1 person in a week is approximately 8.4 kg
The amount of compostable waste that could be generated by one individual in a week would be closest to 8.4kg.
Using this formula
Compostable waste amount=Kg of waste× Number of days in a week× Municipal solid waste percentage
Where:
Kg of waste=2kg
Number of days in a week=7 days
Municipal solid waste percentage=60% or 0.60
Let plug in the formula
Compostable waste amount=2kg×7 days×0.60
Compostable waste amount=8.4 kg
Inconclusion the amount of compostable waste that could be generated by one individual in a week would be closest to 8.4kg.

Which step in the construction of copying a line segment ensures that the new line segment has
the same length as the original line segment?
Answer:
Here are the steps I think you probably will go through.
1. Draw a line that is longer than the segment but shorter than the width of the page.
1a. Make sure this line is at least 1/2 inch from the left hand side.
2. Use a compass to measure the length of the original segment. Never use a ruler. Rulers do not exist in pure geometry.
3. Measure out the distance on the line you just drew with the compass. One end is on the left hand edge and the other end (the pencil end) is marking the segment so it is the same length as the compass. You are done.
The key step either two or three.
Answer: Step Two
Draw a line that is longer than the segment but not wider than the page's width. This line should be at least 1/2 inch away from the left-hand side. After that, measure the length of the original segment with a compass. Following that step, measure the distance along the compass line. (One end is on the left edge, while the other (the pencil end) is used to mark the section so that it is the same length as the compass) Step two is the most important step in the process of copying a line segment to ensure that the new line segment is the same length as the original.

Bob walked 20 miles in 4 hours. Kelly walked 14 miles in 3 hours. Are these rates proportional
Answer:
No
Step-by-step explanation:
20/4=5
14/3=4.67
Since they're not the same, they're not proportional.
Answer:
not proportional
Step-by-step explanation:
First , let's find the speed of each person by dividing the distance traveled and the time.
Using B to represent Bob's speed and K to represent Kelly's speed , we have:
[tex]B=\frac{20}{4} = 5 mph\\K=\frac{14}{3}= 4.666 mph\\\\[/tex]
The speeds 5 and 4.666 are not multiples , so they are NOT proportional.

A rectangular sandbox is surrounded on all sides by a strip of grass that is 5 ft wide on all sides. The length of the sandbox is 4 ft more then width, and the total area for the sandbox and the grass is 189 square feet. Find the dimensions of the sandbox.
Answer:
Dimensions:
Length = 13.256m
width = 9.256m
Step-by-step explanation:
Let the length of the sandbox be = l and its width be = w
The length of the sandbox is 4 ft more than the width.
This means that [tex]l = 4 + w[/tex] ----- equation 1
For the next step, we will be assuming that the strip of grass is a perfect rectangle. The length of the grass strip will be equals to the length of the sandbox.
Area of the grass = length X width = [tex](4 +w) \times 5= 5(4+w)[/tex]------ equation 2
The total area for the sandbox and the grass is 189 square feet.
This means that
[tex](w \times (4+w)) + 5(4+w)=189\\w^2+4w+20+5w=189\\w^2+9w-169=0\\w=9.256m[/tex]
(Kindly note that the positive value for the width was chosen as length cannot be negative).
Now that we have our width, we can put this into equation 1 to get the length.
[tex]l=9.256+4=13.256m[/tex]

A building has 17 floors of offices above ground and 5 floors below ground. Kaylea parks on the 4th floor below ground and has an office on the 15th floor. The ground floor is zero. How many floors must she go up from her car to her office?
Answer:
19 floors
Step-by-step explanation:
Let us consider the ground floor as 0 and the floors above it as positive and the floors below the ground floor as negative.
So, the floor in which she parked is -4 and the floor where her office is at +15.
The number of floors she has to climb is the absolute value of the difference of the two floors.
The number of floors she has to go up is [tex]|-4-15|=19[/tex].
