Answer:

m<A = 84

AC = 9

Step-by-step explanation:

We can find the measure of Angle A by using the sum of interior angles of a triangle theorem.

48+48+A=180

96+A=180

A=84

We can then use the isosceles triangle similarity theorem and reason that since this is an isosceles triangle and one of the side lengths (AB) is 9, the other (AC) would also be 9.

Answer:

  3x -5y = -38

Step-by-step explanation:

The equation of the perpendicular line can be formed by swapping the coefficients of x and y in the given equation, negating one of them. The new constant will be the one that lets the given point satisfy the equation.

  given: 5x +3y = 5

  perpendicular: 3x -5y = constant

At the given point, the constant is ...

  3(-6) -5(4) = -18 -20 = -38

So, the desired equation is ...

  3x -5y = -38

Answer:

4,800

Step-by-step explanation:

(14,700- 1,500) / 2 h 45 m

= 13,200 / 2.75

= 4,800 L/h

Time in minutes between 2 30 and 5 15 = 165 minutes= 2.75 hrs

raise in water level = 14700-1500= 13200

the average rate of increased in volume of water, giving your answer in L/h = 13200/2.75 = 4800 L/h

Answer:

One solution at (-2,1)

Step-by-step explanation:

3x+4y=−2.

2x−4y=−8

Add the two equations together

3x+4y=−2

2x−4y=−8

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

5x +0y = -10

Divide by 5

5x/5 = -10/5

x=-2

Now find y

2x-4y = -8

2*-2 -4y = -8

-4-4y = -8

Add 4 to each side

-4+4 -4y = -8+4

-4y = -4

Divide by -4

y = 1

Answer:

[tex]\left[\begin{array}{ccc}1&0\\0&4\end{array}\right][/tex] [tex]\left[\begin{array}{ccc}x\\y\end{array}\right][/tex] = [tex]\left[\begin{array}{ccc}5\\3\end{array}\right][/tex]

Step-by-step explanation:

A matrix is an algorithm that has many applications. It is composed of a series of numbers (typically coefficients of variables) organized in a pattern. When dealing with a matrix, one must always remember the rule (rows by columns). One such application is that a matrix can facilitate the process by which one solves a system of equations.

When given the following system:

y = 5

4x = 3

One can see that not all of the equations have all variables in them. Yet, bear in mind that any number times zero is zero, therefore, one can rewrite the equation such that it has all of the variables if one ensures that the coefficient of the missing variable is (0).

y + 0x = 5

0y + 4x = 3

Now organize this in the form of a matrix, the coefficients of the variable go in a (4 x 4) since there are now (4) elements. The variables are vertically arranged in a (2 x 1), and the equation results are also vertically arranged in a (2 x 1).

[tex]\left[\begin{array}{ccc}1&0\\0&4\end{array}\right][/tex] [tex]\left[\begin{array}{ccc}x\\y\end{array}\right][/tex] = [tex]\left[\begin{array}{ccc}5\\3\end{array}\right][/tex]

Answer:

The volume of the composite figure is approximately 3567.198 cubic feet.

Step-by-step explanation:

The composite figure consists in the combination of a right cone and a cuboid. The volume of the composite ([tex]V[/tex]), in cubic feet, figure can be determined by this expression:

[tex]V = \frac{1}{3}\cdot \pi \cdot r^{2}\cdot h + w\cdot H \cdot l[/tex] (1)

Where:

[tex]r[/tex] - Radius of the circle of the right cone, in feet.

[tex]h[/tex] - Height of the cone, in feet.

[tex]w[/tex] - Width of the cuboid, in feet.

[tex]H[/tex] - Height of the cuboid, in feet.

[tex]l[/tex] - Length of the cuboid, in feet.

If we know that [tex]r = 10\,ft[/tex], [tex]h = 10\,ft[/tex], [tex]w = 20\,ft[/tex], [tex]H = 7\,ft[/tex] and [tex]l = 18\,ft[/tex], then the volume of the composite figure is:

[tex]V = \frac{1}{3}\cdot \pi \cdot (10\,ft)^{2}\cdot (10\,ft) + (20\,ft)\cdot (7\,ft)\cdot (18\,ft)[/tex]

[tex]V = \left(\frac{1000\pi}{3} + 2520\right)\,ft^{3}[/tex]

[tex]V \approx 3567.198\,ft^{3}[/tex]

The volume of the composite figure is approximately 3567.198 cubic feet.

Answer:

Step-by-step explanation:

take x degree as reference angle

using sin rule

sin x=opposite/hypotenuse

sin x=10/15

sin x=0.66

x=sin 42

therefore x=42 degree

Answer:

1.95

Step-by-step explanation:

area = (1/2 ×1 ×1 )×3 = 1.5 ( for sides)

area = ( 1/2 ×1 ×0.9) = 0.45 for base

area =1.5+0.45 = 1.95

Answer:

m<F = 44°

length of FH = 15

length of GF = 21

Perimeter of ∆FGH = 50

Step-by-step explanation:

✔️Find m<F using the sum of triangle theorem:

The small box indicates angle 90°. Sum of a triangle is 180°. Therefore,

m<F = 180° - (90° + 46°)

m<F = 180° - 136°

m<F = 44°

✔️Find FH using trigonometric function:

Reference angle = 46°

Length of Opposite side = FH = ?

Length of Adjacent side = GH = 14

Apply TOA because we are concerned with the OPP and ADJ sides:

Tan 46° = Opp/Adj

Tan 46° = FH/14

14*Tan 46° = FH

14.4974243 = FH

FH = 15 (approximated to nearest whole number)

✔️Find GH by applying either a trigonometric function or just simply apply pythagorean theorem:

Pythagorean theorem is given as,

c² = a² + b²

c is the longest side (hypotenuse) = GF = ?

a = GH = 14

b = FH = 15

Thus:

GF² = 14² + 15²

GF² = 421

GF = √421

GF ≈ 21 (nearest while number)

✔️Perimeter of ∆FGH = GH + GF + FH

= 14 + 21 + 15

= 50

Answer:

x = 48 degrees

Step-by-step explanation:

(2x + 2) + (x + 34) = 180

3x + 36 = 180

3x = 180 - 36

3x = 144

x = 144 / 3

x = 48 degrees

I hope this helps :)

Answer:

B. x = 48

Step-by-step explanation:

(x + 34)+(2x + 2) = 180°. Angles on a straight line

x+2x = 180 - (34+2)

3x = 180 - 36

3x ÷3 = 144 ÷3

x = 48°
