Can u help solve this step by step?

Answers

Answer 1

Answer:

[tex]\sqrt{28}[/tex]

Step-by-step explanation:

It is given that the triangle (QRS) is right, thus one can use the Pythagorean theorem to solve this problem. The Pythagorean theorem states,

[tex](a)^2+(b)^2=(c)^2[/tex]

Where (a) and (b) are the legs or the sides adjacent to the right angle and (c) is the hypotenuse or the side opposite the right angle. The unknown side in the triangle is a leg, thus, let (b) represent this value. Substitute in the given values and solve,

[tex](6)^2+(b)^2=(8)^2\\\\36+b^2=64\\\\b^2=28\\\\b=\sqrt{28}[/tex]

-5x-9 is greater than or equal to -4

Answers

Answer x is less than or equal to -1

Step-by-step explanation:

-5x-9 -4

-5x-9+9 -4+9

-5x 5

-5x/-5x 5/-5

x less than or equal to -1

Answer:

x [tex]\leq[/tex] -1

Step-by-step explanation:

(-5x - 9) [tex]\geq[/tex] -4

add 9 to both sides of the equation

-5x-9 [tex]\geq[/tex] -4

+9 +9

--------------------

the -9 and +9 cancel out

-5x [tex]\geq[/tex] 5

then, divide both sides by -5 to get x

-5x [tex]\geq[/tex] 5

------ -------

-5 -5

x [tex]\leq[/tex] -1

by the way, the sign changed from [tex]\geq[/tex] to [tex]\leq[/tex] because we divided by a negative number to get x.

Which of these sets of angle measures could be the three angles in a triangle? a 40, 50, 60 b 50, 60, 70 c 60, 70, 80 d 70,80, 90

Answers

Answer:

It’s going to be B. 50+60+70=180 which is how many degrees are in a triangle.

It would be B because 50 + 60 + 70 is 180

Point L is located (5,-5) on the coordinate plane. Point L is reflected over y axis to create point L'. What ordered pair describes the location of L'?

Answers

Answer:

[tex](-5, -5)[/tex]

Step-by-step explanation:

To reflect a point over the y-axis is the same as flipping the sign of the x-value of the point.

So, point L reflect is [tex](-(5)), -5)=\boxed{(-5, -5)}[/tex].

What is the measure of the angle

Answers

Hey! The measure of the angle is 127

The angle is a total of 180 degrees.

We have to find the total of what's in between the two blue lines.

To make it easier, we can take the total of what's not in the blue lines, 53, and subtract it from 180. This gives us 127. So in between both the blue lines, measures 127. Or, you can just count up from 53 to 180 individually.

Answers

Expressions are used to show relationships between variables and constants

The expression [tex]\mathbf{\frac a8 + 6b}[/tex] is a sumThe term [tex]\mathbf{\frac a8}[/tex] is a quotientThe term 6b is a product.

The expression is given as:

[tex]\mathbf{\frac a8 + 6b}[/tex]

In the above expression, a/8 and 6b are added.

So, the expression [tex]\mathbf{\frac a8 + 6b}[/tex] is a sum

In [tex]\mathbf{\frac a8 }[/tex], a is divided by 8.

So, the term [tex]\mathbf{\frac a8}[/tex] is a quotient

Lastly, in 6b; 6 is multiplied by b.

So, the term 6b is a product.

Answers

Answer:

See below

Step-by-step explanation:

a + 54° = 180° [Angles on a straight line]

a = 180 - 54

a = 126°

a + b = 180 [Angles on a straight line add up to 180 degrees]

126 + b = 180

b = 180 - 126

b = 54°

c° = a° [Vertically opposite angles are equal]

c° = 126°

d = 54° [Corresponding angles are equal]

e = a [Corresponding angles are equal]

e = 126°

f = b [Corresponding angles are equal]

f = 54°

g = c [Corresponding angles]

g = 126°

The sum of three numbers is 66. The second number is twice the first and six less than the third. find the numbers

Answers

Step-by-step explanation:

let the 1st number be x

and,

2nd number = 2x

3rd number = 2x + 6

their sum = 66

so, after inserting the values we got

→ x + 2x + 2x + 6 = 66

→ 5x + 6 = 66

→ 5x = 66 - 6 = 60

→ x = 60/5 = 12

→ x = 12

therefore,

1st number = x = 12

2nd number = 2x = 12 × 2 = 24

3rd number = 2x + 6 = 24 + 6 = 30

A local foundation organized a lunch party for all the kids in the community. They ordered a total of 500 burger meals. They ordered plain burgers at $1.75 each cheeseburgers at $2.50 each, and chicken burgers

Answer:

x + y + z = 5002.50x +1.75y +3.20z = 1172.500x +y -z = 100

Step-by-step explanation:

Let x, y, z represent the numbers of cheeseburgers, plain burgers, and chicken burgers ordered for the party.

We have three relations given. Each can be used to write an equation.

x + y + z = 500 . . . . . . . . . a total of 500 meals were ordered

2.50x +1.75y +3.20z = 1172.50 . . . . . the total cost

0x +y -z = 100 . . . . . . . . . . 100 fewer chicken were ordered than plain

Additional comment

We put the coefficient of x as 0 in the last equation to facilitate writing this system as an augmented matrix.

The solution is (x, y, z) = (300, 150, 50).
