Round to 3 SF
827.3 pls help I have to send it to the teacher in 5 minutes

Answers

Answer 1

Answer:

Step-by-step explanation:

If I'm reading your shorthand correctly you want this to be rounded to 3 digits.

There are two answers:

1) 8.27 * 10^2         which is the best way to show 3 significant digits or

2) 827                    which works but is not as good as the scientific notation.

The reason is that you cannot be absolutely sure how many digits there are. It might just be a convenient way to show a number informally without worrying about significant figures.

True or False. To find the missing side length in the diagram, use the Pythagorean Theorem.

Answer: A

Answers

True.
The Pythagorean theorem is a^2 + b^2 = c^2 where a^2 and b^2 are the two legs of the triangle (two sides connected by the right angle) and c is the hypotenuse (longest side, opposite the right angle).

To solve using the Pythagorean theorem, plug in sides AC and CB into a and b, then solve for c.

23^2 + 31^2 = c^2
529 + 961 = c^2
c^2 = 1490
c = √1490 = 38.601

Find x and y in the given figure

Answers

Answer:

x= 70°, y=40°

Step-by-step explanation:

2x=140

x= 70

y= 180-140= 40

140 + y = 180

y = 180 - 140

y = 40

2x + 40 = 180 (Angle Sum Property)

2x = 180 - 40

2x = 140

x = 140/2

x = 70

X = 70

Y = 40

Step-by-step explanation:

A farmer grows x acres of peas and y acres of tomatoes. He has 12 acres available to plant peas and tomatoes. Write an inequality in x and y to satisfy this condition. The number acres of tomatoes planted must not be more then twice the number of acres of peas planted. Write an inequality in x and y to satisfy this condition.​

Answers

Answer:

Y < 2X

Step-by-step explanation:

Let the acres of land on which pea is to be cultivated is "X" acres and the acres of land on which tomato is to be cultivated is "Y"

It is given that number acres of tomatoes planted must not be more then twice the number of acres of peas planted

Thus, [tex]Y < 2X[/tex]

[tex]X + Y = 12[/tex] acres

[tex]Y = 12-X[/tex] acres

Thus,

[tex]12 - X \leq X\\12\leq 2X\\6 \leq X[/tex]

Let us take X = 6 , Then Y = 13-6 = 6

Anyone know the answer to this question?

Answers

Answer:

m<1 = m<2 = 98

Step-by-step explanation:

the measurement of angle 1 and 2 are the same because the two triangle half's (top and bottom) of the polygon are congruent.

any 4 sided polygon has sums of their internal angles = 360 degrees.

(for example a square has four 90 degrees angles, 360=90+90+90+90)

we know that 2 angles are 90 and 74,

we also know that the 2 other angles (m<1 and m<2) are the same,

m<1 +m<2 +90 +74=360

m<1+m<2=360-90-74

2*m<1=196

m<1=196/2

m<1=98

m<2=98

Complementary angles are two angles whose
measures add to 90°. The ratio of the measures of
two complementary angles is 7:11. What are the
measures of the angles?

Answers

Answer:

let the two complementary angles be x and 90-x

x= 7t (say)

90-x= 11t

x+90-x=90= 7t+11t=18t

90=18t

t=90/18= 10/2= 5

so x= 7×5=35 degrees

and 90-×=90-35=55 degrees

Answer:

Step-by-step explanation:

Say thanks

mark brainlist

and rate 5!

x= 7t (say)

90-x= 11t

x+90-x=90= 7t+11t=18t

90=18t

t=90/18= 10/2= 5

so x= 7×5=35 degrees

and 90-×=90-35=55 degrees

C. right


D. it does not make a triangle

Answers

Answer:

Obtuse

x=130

90<130

Thus, the triangle is obtuse

The Sugar Sweet Company will choose from two companies to transport its sugar to market. The first company charges $7500 to rent trucks plus an additional fee of $150.25 for each ton of sugar. The second company charges $7143 to rent trucks plus an additional fee of $175.75 for each ton of sugar.​

Answers

Answer:

14 tons of sugar

$9603.5

Step-by-step explanation:

For what amount of sugar do the two companies charge the same?

What is the cost when the two companies charge the same?

Let

x = ton of sugar

Company A:

7500 + 150.25x

Company B:

7143 + 175.75x

1. Equate company A and company B

7500 + 150.25x = 7143 + 175.75x

7500 - 7143 = 175.75x - 150.25x

357 = 25.50x

x = 357/25.50

x = 14 tons of sugar

2. Cost when both companies charge the same

Company B:

7143 + 175.75x

= 7143 + 175.75(14)

= 7143 + 2460.5

= 9603.5

Company B = $9603.5

Company A:

7500 + 150.25x

= 7500 + 150.25(14)

= 7500 + 2103.5

= 9603.5

Company A = $9603.5

Graph this: y = 2sIn(x) - 3

Insert picture of graph

Answers

Answer:

We have the function:

f(x) = 2*sin(x) - 3

To graph this type of functions is useful to understand the parts of the function.

A general one is written as:

g(x) = A*sin(w*x + p) + M

where:

A is the amplitude

w is the angular frequency.

p is the phase

M is the midline.

Then in this case we have an amplitude of 2, an angular frequency of 1, a phase of 0 radians and the midline y = -3

Now we can evaluate the function in different points and (knowing how a sine function behaves) connect them, the graph will look something like this:

10x+20=145​

Answers

First you need to take away 20 so you subtract that and then subtract 20 to 145 also

10x + 125

Now you have to take away 10 from x and since it’s multiplying you need to divide it by 10, and you have to divide ten to 125 as well.

x = 12.5

8 times 4 is 32, and 80/32 is 2.5. When you have to find another measurement and you know 2 of them, you just have to divide the total of the 2 measurements with the volume. it would be 2.5 feet as the height.
