Answer:
1. y = 145
2. y = 145 and z = 215
3. y = 180 - x
4. y = 180 + x and z = 360 - x
5. y = 360 - x
6. y = 180 - x and z = 180 + x
Step-by-step explanation:
1. siny = sin35
Since sin35 is positive, siny is in the second quadrant.
So siny = sin(180 - 35) = sin35
siny = sin145 = sin35
Since siny = sin145, y = 145
2. cosy = cosz = -cos35
since -cos35 is negative in the second and third quadrant,
cosy = cos(180 - 35) = -cos35 and cosz = cos(180 + 35) = -cos35
cosy = cos145 = -cos35 and cosz = cos215 = -cos35
Since cosy = cos145 and cosz = cos215,
y = 145 and z = 215
3. If siny = sinx and x < 90,
since x < 90, sinx is in the first quadrant and siny is in the second quadrant since it is positive
siny = sin(180 - x) = sinx
Since siny = sin(180 - x)
y = 180 - x
4. siny = sinz = -sinx and x< 90
since -sinx is negative and sine is negative in the third and fourth quadrant respectively, siny and sinz are in the third and fourth quadrant,
siny = sin(180 + x) = -siny and sinz = sin(360 - x) = -sinx
Since siny = sin(180 + x) and sinz = sin(360 - x)
y = 180 + x and z = 360 - x
5. cosy = cosx and x < 90
Since cosx is positive in the first and fourth quadrant, and x is in the first quadrant,
cosy = cos(360 - x) = cosx
cosy = cos(360 - x)
y = 360 - x
6. cosy = cosz = -cosx and x< 90
since -cosx is negative in the second and third quadrant,
cosy = cos(180 - x) = -cosx and cosz = cos(180 + x) = -cosx
cosy = cos(180 - x) and cosz = cos(180 + x)
y = 180 - x and z = 180 + x
Darcie wants to crochet a minimum of 3 blankets to donate to a homeless shelter. Darcie crochets at a rate of {1}{15} start fraction, 1, divided by, 15, end fraction of a blanket per day. She has 60 days until when she wants to donate the blankets, but she also wants to skip crocheting some days so she can volunteer in other ways. Write an inequality to determine the number of days, sss, Darcie can skip crocheting and still meet her goal.
Answer:
s ≤ 60 - (3 ÷ 1/15)
Step-by-step explanation:
Minimum of blankets to crochet = 3
She has 60 days to crochet
She crochet at a rate of 1/15 of a blanket per day
Therefore to crochet 1 blanket
Number of days needed =x
1 blanket = rate per day * x days
1 = 1/15 * x
1 = 1/15x
Divide both sides by 1/15
x = 1 ÷ 1/15
= 1 × 15/1
= 1×15
x = 15
15 days needed to crochet 1 blanket
To crochet 3 blanket = 15 days × 3 blanket
=45 days needed.
Darcie can skip = 60 days - 45 days
= 15 days
The inequality to determine the number of days, s, Darcie can skip crocheting and still meet her goal.
s ≤ 60 - (3 ÷ 1/15)
Solving the inequality
s ≤ 60 - (3 ÷ 1/15)
s ≤ 60 - (3×15/1)
s ≤ 60 - 45
s ≤ 15
Answer:
s ≤ 60 - (3 ÷ 1/15)

Dion bought tickets for the fun park so that he and his friends would each have the same number of tickets. There are enough tickets so that each person can ride the go-carts once, play video games three time, and play laser tag twice.
When Dion purchased the tickets for himself and his eight friends, he realized that he could purchase ticket books, individual tickets, or a combination of books and individual tickets. Dion figured out the cheapest way to buy tickets for his group. What was the total cost?
Please I would appreciate it a lot ❤️
Answer:
25
Step-by-step explanation:
;\
The required cheapest way to buy tickets is by buying 7 ticket books and 3 individual tickets.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
Consumption of tickets for each person can ride the go-carts once, play video games three times, and play laser tag twice,
= 4 + 1*3 * 2*6
= 19
So each person conceded 19 tickets,
Total ticket conceded by 9 persons,
= 19 * 9
= 171 tickets
Now the cheapest option is given by,
A ticket book consists of 24 tickets so,
Dividing 171 by 24 the quotient will be the number of books and the remainder will be the individual tickects for the cheapest purchase,
= 171 / 24
= 7 + 3 / 24
quotient = 7
remainder= 3
Thus, the required cheapest way to buy tickets is by buying 7 ticket books and 3 individual tickets.

What is the value of x?
Enter your answer in the box.
Answer:
Value of x is 90°
Step-by-step explanation:
Why?Imagine it as a shape of circle.
Circle has a measurement total of 360°
Semi cirlcle(half of the circle) is equivalent to 180
Now,
The bottom semi circle has a 146°
The top has a 56°
You can simply compute it by subtracting them.

Is it possible to have a triangle with two right angles? Explain your reasoning.
Answer:
No
Step-by-step explanation:
For something to be considered a triangle, the sum of its angles must be 180 degrees. Right angles are 90 degrees. And since triangles must have 3 angles, it could not work. 80+80 exceeds 180.
WILL MARK YOU BRAINIEST HURRY PLZ
Acute triangle; m<CDB = 180 - 130 = 50 and m<2 = 180 - 70 - 50 = 60.
remember that all angles in a triangle add up to 180°.
And angles on a straight line add up to 180°.

4(6x - 10) = 8x + 40
Answer:
5
Step-by-step explanation:
24x-40=8x+40
plus 40
24x=8x+80
then u subtract 8
then u get 16x
then 80 divied by 16
u get 5
Answer:
x = 5
Step-by-step explanation:
4(6x -10) = 8x + 40
24x - 40 = 8x + 40
now were going to get the variable and the numbers on different sides
24x - 40 + 40 = 24x
8x + 40 - 8x = 40
24x - 8x = 16x
40 + 40 = 80
16x = 80
now divide each side by 16
16x / 16 = x
80 / 16 = 5
x = 5

Rani is making rice pudding. She uses 3/4 cup of white rice for every 2 cups of milk. how many cups of rice does she need when she uses 3 cups of milk
Answer:
9/4 cups or 2 1/4 cups.
Step-by-step explanation:
Since she uses 3/4 for every 2 cups, then we have to find out what she makes per cup. We have to divide 3/4 in half and to do that, we want to scale up 3/4 making it 6/8 which is congruent to 3/4.
Now we divide 6/8 in half which is 3/8.
Then we multiply that by 3, 6 times 3 is 18. So now it is 18/8 cups. We can now scale down and simplify it more.
To do that, we just divide the fraction by 2 to make to denominator into 4. Because of that, our answer is 9/4 cups or 2 cups and 1/4 cup.
Cups of rice uses for every 3 cup of milk is [tex]1\frac{1}{8}[/tex] cups
Given:
Cups of rice uses for every 2 cup of milk = 3/4 cup
Find:
Cups of rice uses for every 3 cup of milk
Computation:
Cups of rice uses for every 1 cup of milk = (3/4) / 2
Cups of rice uses for every 3 cup of milk = [3 / 8]3
Cups of rice uses for every 3 cup of milk = 9 / 8
Cups of rice uses for every 3 cup of milk = [tex]1\frac{1}{8}[/tex] cups

2(u-1)-6= -5(-4u+4) -3u
Answer:
u = 4/5
Step-by-step explanation:
Expand
2u - 2 - 6 = 20u - 20 - 3u
Rearrange with like terms on either side
12 = 15u
u = 4/5
Answer:
u=4/5
Step-by-step explanation:
First, parentheses/multiply on both sides.
2u-2-6=20u-20-3u <--- two negatives make a positive
Next, add/subtract like terms.
2u-8=17u-20
Then, add 8 to both sides.
2u=17u-12
Finally, get "u" by itself. Subtract "17u" to both sides and then divide "-15" to both sides
-15u=-12
u=4/5
