Answer:

Step-by-step explanation:

"A fifteen-foot ladder leans against a wall at 52°."

Do you mean that the ladder makes a 52° angle with the wall?

x = distance between foot of ladder and base of wall

sin(52°) = x/15

x = 15sin(52°) ≅ 11.82 ft

Or, did you meant that the ladder makes a 52° angle with the ground?

cos(52°) = x/15

x = 15cos(52°) ≅ 9.23 ft

Answer:

x=30°

y=30°

Step-by-step explanation:

x= 180-150=30°

y)

180=30 + 90 + z

z +120 = 180

z= 60

90-60=y

y=30

30°

Given:

Consider the three number are given by:

[tex]a=x^2-y^2[/tex]

[tex]b=2xy[/tex]

[tex]c=x^2+y^2[/tex]

To find:

The three numbers are the Pythagorean triple generated by using 4 for x and 1 for y.

Solution:

We have,

[tex]a=x^2-y^2[/tex]

[tex]b=2xy[/tex]

[tex]c=x^2+y^2[/tex]

Substituting 4 for x and 1 for y, we get

[tex]a=4^2-1^2[/tex]

[tex]a=16-1[/tex]

[tex]a=15[/tex]

Similarly,

[tex]b=2(4)(1)[/tex]

[tex]b=8[/tex]

And,

[tex]c=4^2+1^2[/tex]

[tex]c=16+1[/tex]

[tex]c=17[/tex]

The three three numbers are the Pythagorean triple are 8,15 and 17.

Therefore, the correct option is C.

Answer:

The number is -10

Step-by-step explanation:

I will answer this while I read through the question.

Let the number be x

Divide by 2

[tex]\frac{x}{2}[/tex]

Add 9 to it

[tex]\frac{x}{2} + 9[/tex]

It gives 4

[tex]\frac{x}{2} + 9 = 4[/tex]

Now, we solve for x

Collect Like Terms

[tex]\frac{x}{2} = 4-9[/tex]

[tex]\frac{x}{2} = -5[/tex]

Make x the subject

[tex]x = -5 *2[/tex]

[tex]x = -10[/tex]

Answer:

[tex]9[/tex]

Step-by-step explanation:

As per the problem, the given triangle is a right triangle. This is signified by the box around one of its angles, this box states that the angle it is surrounding is a right angle.

Since it is a right triangle, one can use the Pythagorean theorem to solve this problem. The Pythagorean theorem states that; ([tex]a^2 + b^2 = c^2[/tex]), where ([tex]a[/tex]) and ([tex]b[/tex]) are the legs of the right triangle, or the sides adjacent to the right angle. ([tex]c[/tex]) is the hypotenuse or the side opposite the right angle.

Substitute in the given values and solve, note that ([tex]a[/tex]) represents the unknown leg (side).

[tex]a^2 + b^2 = c^2\\\\a^2 + (\sqrt{19})^2 = (100)^2\\\\a^2 + 19 = 100[/tex]

Inverse operations,

[tex]a^2 + 19 = 100\\-19\\\\a^2 = 81\\\\a = \sqrt{81}\\\\a = 9[/tex]

Answer:

1) 27

2) 2/5

3) 1

4) 1.5 lbs

Step-by-step explanation:

1) First, 8505/315 = 27

2)I don't really have an explanation for this one-

3) 2/3 = 6/9. 6/9 + 3/9 = 1

4) 4/8 x 3 = 1.5

1. 2

8,505 ÷ 315 = 27

2. 2 ÷ 5

Fractions are division problems so it would be 2 divided by 5

3. 9/9 or 1

Make them have the same denominator

2/3 + 3/9 = 6/9 + 3/9 = 9/9 = 1

4. 1 ½

4/8 simplified is ½ so you should do ½ x 3 = 1 ½

5. The baker needs 750 more grams

Multiply 2.5 by 1000, which is 2500

That’s how many grams the baker needs, now you need to do 2500 - 1750

Which is 750 grams

Answer:

6 gallons

Step-by-step explanation:

You can find this using the ration method.

If, 8 gallons : 192 miles

   x gallons : 144 miles

We must find the value of x, which is the number of gallons used to travel 144 miles.

Cross multiply the ratios.

192 x = 8 × 144

192 x = 1152

x = 1152 ÷ 192

x = 6

∴ It takes 6 gallons to travel 144 miles.

Answer:

(-4, -1) (see below)

Step-by-step explanation:

Substitution means that you actually replace, or "substitute," the value of the variable in.

Here, y = -1, so -3x - 8y = 20 can be written as:

-3x - 8 (-1) = 20

We can now solve for x:

-3x + 8 = 20

-3x = 12

x = -4

Putting this into (x, y) format equals:

(-4, -1)

Answer:

For this equation you be inverse operation giving you the answer -6

further information down below :)

Step-by-step explanation:

Your goal for this is to isolate the variable which is x.

First, find the operation opposite of addition which is subtraction

When you add that operation to both sides with the constant(2)

2 and 2 cancel each other out, but to the for the term(4) 4-2=2

after that you have your new term which is x/-3=2

You do the same thing but to in division because the opposite of multiplication is division in this case you multiply -3 to both sides -3*-3 cancel each other out, now you have-3*2= negative times a positive equal negative in anyway so, overall you get -6.  

To check:

you do the full equation now that you have isolated the variable, you now can do the operations normally which are. -6/-3=2 because when you divide a negative by a negative you get a positive end out with 2+2=4 which is correct and match the sum.

This means that our answer is correct :)

Answer:

Perimeter

Hope it helps!

The distance around the edge of a figure is its Perimeter.

To complete the following statement. The distance around the edge of a figure is its ____.​

Perimeter is the measure of the length of the figure on its circumference.

Since in the question blank, space is given following the definition,
The distance around the edge of a figure is perimeter because the measure of the boundary of any figure is termed as its perimeter.
For example, the Perimeter of the rectangle is the total measure of the two-time measures of length and width. For the Perimeter of the square, it is 4 times the length of one side. For the Perimeter of the circle, it is 2π times of radius.

Thus, the distance around the edge of a figure is its Perimeter.
