Answer:
24%
Step-by-step explanation:
x-(11/100)x
89/100x
followed by
89/100x-13/100x
76/100x
so the total decrease is calculated as
x-76/100x
(24/100)x
i.e 24% decrease

Answer:
The slope is 1
Step-by-step explanation:
(2, 1) and (-4, -5)
Slope:
m=(y2-y1)/(x2-x1)
m=(-5-1)/(-4-2)
m= (-6)/(-6)
m = 1
Answer:

Solve for x (Geometry)
Answer:
x = 18[tex]\sqrt{2}[/tex]
Step-by-step explanation:
The middle line divides the 90° angle in half meaning your triangles are isosceles triangles. Recall that an isosceles triangle has sides that are the same length.
Using pythagorean theorem a² + b² = c², you can solve for x
18² + 18² = x²
x² = 648
x = 18[tex]\sqrt{2}[/tex]

co-terminal angle for -960... can you tell me? :D w/o looking at my answer below?
Your answer for co-terminal angle is ______________ :)
960 - 360 = 600
600 - 360 = 240
this is telling us that going in a clock wise direction.. as the -960 is, that the co-terminal angle is 240, which seems about right.. looking at the graph. so now. let's take 240 away from 360 to find that co-terminal angle but going in the positive direction or the counter clock wise direction
360-240 = 120
and yes.. that does look like 120 ° going in the positive direction.
now do you know the sec identity to use sin and cos???
look at the below diagram
sin sec
cos csc
tan cot
the trig function line up like that for a reason
sin 1/sin
cos 1/cos
sin/cos cos/sin
I put them in their sin and cos identities.. see.. they all line up that way
sec = 1/sin
csc = 1/cos
tan = sin/cos
cot = cos/sin
now... find
sec(120) = 1/sin(120)
do you know how to find sin(120) ?????
put it back to it's co-terminal angle in the 1st quadrat... I hope you know how to do this.. i'll just speed along... assuming you do
sin(120) = sin(60)= √3/2
so sec(120) = 1 / √3/2
so sec(120) = 2/ √3
10)
csc(315) = 1/cos(315)
find the co-terminal angle that you know in the 1st quadrant again...
so 315 = 45 in the 1st quadrant.. I just looked and can see that
so
csc(315) = 1/cos(315 = 1/cos(45) and cos(45) = √2/2
so then 1 / √2/2 = 2 / √2
csc(315) = 2 / √2
what i'm really wondering about.. is .. where is question 9)
:DDD
Linda is making a quilt for her granddaughter. She bought 3 1/4 yards of fabric. Her total cost was $10. What was the cost per yard?
(Complex fraction)
Answer:
13 /40

If a circle is cut from a square piece of fabric, how much fabric would be leftover? Use 3.14 for pi. (round to nearest hundredth).
Answer:
0.22 square units
Step-by-step explanation:
Area of the left over fabric = Area of the square piece - Area of the circle
let the side length of the square piece be 1 unit
Area of the square piece = 1 * 1
Area of the square piece = 1 square units
Area of the circle = πd²/4
d is the diameter of the circle = 1 unit (equivalent to the side length of the square)
Area of the circle = π(1)²/4
Area of the circle = 3.14/4
Area of the circle = 0.785square units
Area of the left over fabric = 1- 0785
Area of the left over fabric = 0.215 square units
Hence the amount of fabric that would be leftover is 0.22 square units
Answer:
0.22 square units

Given an example of a binomial and an example of a trinomial.
Answer:
Step-by-step explanation:
A binomial might look like x + 2. Note how it has two terms. " bi' " is a prefix meaning " two. "
A trinomial might look like 2x^2 - x + 1. It has three terms.

There are 60 calico cats at the animal shelter if this represents 30% of the cats in the shelter how many total cats are there
Answer: 200 cats in total
Step-by-step explanation:
60 calico cats represents 30% of the total cat population in the shelter.
That means that if we find 30% of the total number of cats, the number we will get is 60.
Assuming the total is x, representing this in equation form makes it:
x * 30% = 60
x = 60 / 30%
x = 200 cats in total

Problem: Jessica ordered a pizza. One-half of the pizza had pepperoni only, one-sixth of the pizza had mushrooms, and the rest of the pizza was cheese only. What fraction of the pizza was cheese only?
Answer:
1/3 of the pizza
Step-by-step explanation:
Number of pizza ordered = 1
pepperoni only part = One-half of the pizza = 1/2 of the pizza
Mushrooms part = one-sixth of the pizza = 1/6 of the pizza
Cheese only part = x
Total pizza = pepperoni only part + Mushrooms part + Cheese only part
1 = 1/2 + 1/6 + x
1 = (3+1) /6 + x
1 = 4/6 + x
1 - 4/6 = x
x = 1 - 2/3
= (3-2) / 3
x = 1/3 of the pizza
Cheese only part = x = 1/3 of the pizza

Manoj went to the shopping mall and saw the price list in the shoe store as mentioned below in
the table. Then, he decided to buy pair of casual shoes and formal shoes. So, he gave 4 notes of
Rs. 1000. He was returned 5 notes in denominations of Rs. 500 and Rs. 100. How many notes of
Rs. 500 and Rs. 100 did he get? Find out.
Type of Pair of Shoes
Price List
Casual Shoes
Rs.1,300
Formal Shoes
Rs. 1,800
Sports Shoes
Rs. 1,400
Answer:
A Rs. 500 note, and four Rs. 100 notes.
Step-by-step explanation:
The cost of the two shoes = Rs.1,300 + Rs. 1,800
= Rs. 3,100
He gave 4 notes of Rs. 1,000 = 4 x Rs. 1,000
= Rs. 4,000
Manoj's expected change = Rs. 4,000 - Rs. 3,100
= Rs. 900
Since he was returned 5 notes in the denominations of Rs. 500 and Rs. 100, then;
Rs. 500 + Rs. 100 + Rs. 100 + Rs. 100 + Rs. 100 = Rs. 900
Therefore, Manaoj was returned a Rs. 500 note, and four Rs. 100 notes.
