HELP PLEASE!!!What Is The Measure Of /_BAC?5080100130

Answers

Answer 1

Answer:

<BAC = 80

Step-by-step explanation:

All triangle angles equal 180

<BAC = x

x + 50 + 50 = 180

x + 100 = 180

x = 180 - 100

x = 80

Answers

Answer:

30 Kilometers

Step-by-step explanation:

The longest measure from the given measures is 30 kilometers.

A no. of measurement values are given in the question.

We have to find out which is the longest from them.

What is the meaning of unit conversion ?

A unit conversion is done to express the same property as a different unit of measurement.

As per the question ;

Some measures i.e., 90 centimeters, 40 meters, 30 kilometers, 10 meters, 40 millimeters are given.

Let's check which is the longest by converting them all in same units say centimeters.

So ;

a) 90 centimeters

= 90 centimeters

b) 40 meters

= 40 × 100 centimeters

= 4000 centimeters

c) 30 kilometers

= 30 × 1000 meters

= 30000 × 100 centimeters

= 3000000 centimeters

d) 10 meters

= 10 × 100

= 1000 centimeters

e) 40 millimeters

=  40 / 10 centimeters

= 4 centimeters

So ; the longest is 30 kilometers.

Thus , the longest measure from the given measures is 30 kilometers.

One brand of horse feed is made of oats and barley. The ratio of oats to barley is 4 : 11 by mass. How many kilograms of each grain are needed to make 150 kg of feed? (Show your thinking)

Answers

Answer:

Below in bold.

Step-by-step explanation:

Fraction of oats = 4/(4+11) = 4/15

So fraction of barley = 11/15

Weight of oats in 150 kg = 150 * 4/15 = 40 kg

and there are 110 kg of barley,

There are 40 kg of oats and 44 kg of barley.

What is mean by Ratio?

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.

We have to given that;

The ratio of oats to barley is 4 : 11 by mass.

Here, The mass of oats = 4x

And, The mass of barley = 11x

Since, There are 150 kg feed.

Hence, We get;

⇒ 4x + 11x = 150

⇒ 15x = 150

⇒ x = 10

Thus, The mass of oats = 4x

                                    = 4 × 10

                                    = 40 kg

And, The mass of barley = 11x

                                      = 11 × 4

                                      = 44 kg

The base of a triangle is eleven feet less than
four times its height. If the sum of the lengths of
the base and height of the triangle is 49 feet,
find the area of the triangle.

Answers

Answer: 129 Feet

Step-by-step explanation:

You can make an equation where Height=h, and Base=b. So going backwards with the first question, the base will equal 4 times the height: b=4h, and 11 less. b=4h-11. The the other equation will be just that the base plus the height is 49. b+h=49. Then you put that into y=mx+b form. The first equation already is, and the second equation would be b=49-h. So, since the equations equal the same things, you throw away the b. Then you make a new equation by having 4h-11 equal 49-h. Since this is true seeing as they are the same triangle. Then you just use propreties of equality for the equation. You end up with 5h=60. The. You divide 60 by 5 to make 5h just equal h. So you get h=6. Then, like the qeuation said, the base (unknown) plus the height (6) is 49. So to get from 6 to 49, the answer is 43. The formula for that area of a triangle is (base x height) /2 = area. So 43 times 6 is 258. Then divided by 2 is 129. So the area of the triangle is 129.

The area of the triangle is 222 square feet.

Area of a triangle

The formula for calculating the area of the triangle is expressed as:

A = 0.5bh

b is the base of the triangleh is the height of the triangle

The base of a triangle is eleven feet less than  four times its height,

b = 4h - 11

Also, if the sum of the lengths of  the base and height of the triangle is 49 is expressed as:

b + h = 49

4h-11+h = 49

5h = 49 + 11

5h = 60

h = 12

Since 4h = b + 11

4(12) = b + 11

b = 48 - 11

b = 37

A = 0.5(12)(37)

A = 222ft^2

Hence the area of the triangle is 222 square feet.

What is the area of the trapezoid below?

Answers

Answer:

A = 180 units²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the perpendicular height and b₁, b₂ the parallel bases

The triangle on the left is right with h = 24 (7- 24- 25 triangle )

Here h = 24, b₁ = 4 and b₂ = 7 + 4 = 11 , then

A = [tex]\frac{1}{2}[/tex] × 24 × (4 + 11) = 12 × 15 = 180 units²

For what values of x are the following expressions equal to each other.
the binomials x^2 - 6x and 5x-18

Answers

Answer:

x = 9, 2

Step-by-step explanation:

Move all terms to the left side and set equal to zero. Then set each factor equal to zero.

The values of x that make the expressions x² - 6x and 5x - 18 equal to each other are x = 2 and x = 9.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

To find the values of x that make the expressions  x²  - 6x and 5x - 18 equal to each other

We have to set them equal to each other and solve for x:

x² - 6x = 5x - 18

x²  - 11x + 18 = 0

Next, we can factor this quadratic equation:

(x - 2)(x - 9) = 0

Now we can use the zero product property and set each factor equal to zero:

x - 2 = 0 or x - 9 = 0

Solving for x, we get:

x = 2 or x = 9

Therefore, the values of x that make the expressions x² - 6x and 5x - 18 equal to each other are x = 2 and x = 9.

Answers

Answer:

The width of the box is 5 in

Step-by-step explanation:

the formula for the volume of a rectangular box of length L, width W and height H is V = L*W*H.  Here we know V, L and H and want to find W.  Solving this equation for W, we get W = V/(LH).

With V = 180 in^3, H = 4 in and L = 9 in, W comes out to be

            180 in^3

  W = ------------------ = 5 in

            (4 in)(9 in)

The width of the box is 5 in

Answer:

Solution :-

We have

[tex] \begin{cases} \sf Volume = \frak{480 \: cu \: cm}\\ \sf Length = \frak{4 \: in} \\ \sf Height = \frak{4 \: in}\end{cases}[/tex]
