I need help I don't know what to do
Answers
Answer:
Step-by-step explanation:
so you understand what to do, or what they want you to figure out.
AD is an "arc length" . So they want to know the length, in degrees. along the circle , from A to D. Why didn't they just say so, huh. :D well, they kinda did, but not as clear as they could have.
next. you need to know how far around a circle is all the way around?
if you guessed 360°, you are right
next because they gave us that angle of 93° we know all the angles around the point E, complimentary angles add to 180 so 180-93 = 87°. That's the to the left of 93 and directly below it too. This is the answer to the 2nd question ∠DEC= 87°
we can only write arc length of AD in respect to what we know about the circle.
so, arc length of AD is 161° + BA + AD + DC = 360
or getting AD by it self , then
AD =360 -161 -BA -DC
AD = 199°-BA-DC
maybe that's all you need to do, also i'm wondering if there is some more info about this problem , maybe at the top of the page? of off the screen?

A DVD was priced at $2.87 last week. This week the same DVD is priced at $10.59. What is the percent increase in price?
Answers
Answer:
Percentage increase = 269%
Step-by-step explanation:
Price of a DVD last week = $2.87
Price of the same DVD this week = $10.59
Increase in the price of DVD between last week and this week = 10.59 - 2.87
= $7.72
Therefore, percentage increase in the price of DVD = [tex]\frac{\text{Increase in the price}}{\text{Price of DVD last week}}\times 100[/tex]
= [tex]\frac{7.72}{2.87}\times 100[/tex]
= 268.99
= 269%

Answers
Answer:
x = − 3
Step-by-step explanation:
Let's solve your equation step-by-step.
− 2x − 4 = x + 5
Step 1: Subtract x from both sides.
− 2x − 4 − x = x + 5 − x
− 3x − 4 = 5
Step 2: Add 4 to both sides.
− 3x − 4 + 4 = 5 + 4
−3x = 9
Step 3: Divide both sides by -3.
−3x / −3 = 9 / −3
x = − 3

Cierto tipo de mezcla contiene 5kg de arena y 3 kg de cemento: un constructor necesita 12 toneladas de esta mezcla. ¿qué cantidad se necesita de arena y de cemento?
Answers
Answer:
the sand and cement needed is 7.5 kg and 4.5 kg respectively
Step-by-step explanation:
The computation of the sand and cement needed is shown below:
Given that
The mix of sand and cement is 5kg and 3kg i.e. its ratio is 5:3
And there is a 12kg of mix of both things
So individually it required
For sand = 12 × 5 ÷ 8
= 7.5 kg
For cement = 12 × 3 ÷ 8
= 4.5 kg
Hence, the sand and cement needed is 7.5 kg and 4.5 kg respectively
The area of the triangle below is 5/12 square feet. What is the length of the base? Express your answer as a fraction in simplest form.
1/2 ft is the height
Answers
Answer:
5/4 ft
Step-by-step explanation:
Given data
Area= 5/12 square feet
Height= 1/2 ft
Base=????
We know that the area of a triangle is given as
Area= (1/2)B*H
substitute
5/12= 1/2* B* 1/2
5/12= B/4
cross multiply
12B= 20
B= 20/12
B= 5/3
Hence the base is 5/4 ft

Intercepts:
Write the ordered pair describing the coordinates of each intercept.
1. x-intercept: -6 2. y-intercept: -2.3 3. y-intercept: 3/4
Find the x-intercept and y-intercept for the graph of each equation.
4. y = 3x – 9 5. y = 5x + 10 6. y=1/2 x+4
7. y = 12 – 6x 8. 2y = -6x + 8
Use the x-intercept and y-intercept to graph each equation.
9. y=-1/2 x-3 10. y = 2x + 4
x-intercept: ______ x-intercept: ______
y-intercept: ______ y-intercept: ______
Graph your answers from #4 and #8 from above.
11. y = 3x – 9 12. 2y = -6x + 8
Answers
The y-intercept is the point where the function crosses the y axis at x=0
1. It is an x-intercept, so y = 0. The ordered pair would be (-6, 0)
2. It is a y-intercept, so x = 0. The ordered pair would be (0, -2.3)
3. It is a y-intercept, so x=0. The ordered pair would be (0, 3/4)
To find the x-intercept, set y = 0. To find the y-intercept, set x=0
4. y-intercept: y = 3(0) -9. y = -9 The y-intercept is at (0, -9)
x-intercept: 0 = 3x -9. 9 = 3x. x = 3. The x-intercept is at (3, 0)
5. x intercept: 0 = 5x +10. -10 = 5x. x = -2. The x-intercept is at (-2, 0)
y-intercept: y = 5(0) + 10. y = 10. The y-intercept is at (0, 10)
If you look at finding the y-intercepts in the two problems above, you may see there is a pattern forming. The y-intercept is the number that your adding or subtracting that is located after the x (ex. y = 4x - 2 - the y-intercept would be -2)
9. First, find the x and y-intercepts. The y intercept is -3 You’d graph that at (0, -3). 0 = -1/2x - 3. -1/2x = 3. x = -6 so the x-intercept is at (-6, 0). If you only need to graph 2 points, then you can graph just those two points and draw a line between them.
To graph y=-1/2x + 3, start at the y-intercept and use the slope (-1/2) to find other points. Because your slope is -1/2, you’d go down 1 unit and then to the right 2 units. That would be your next point. If you wanted your line to go further up, go up one unit and then to the left 2 units. That would be your next point.

For the first part of 4 questions wrong: he would get 42 points

For the first part of 4 questions wrong: he would get 42 points because 50 divided by 2 is 25 and 25 minus 4 is 21 and 21 times 2 is 42.
For the last part I'm guessing x = 1 so again 50 divided by 2 is 25 and 25 minus 1 is 24 and 24 times 2 is 48
