What is the answer to this math question

Mathematics
1 answer:
mezya [45]3 years ago
8 0

Answer:

11

Step-by-step explanation:

1.80m + 0.6s = 12.00

[substitute the value of m into the equation]

1.80×(3) + 0.6s = 12

5.4 + 0.6s = 12

[make s the subject of the formula]

0.6s = 12 - 5.4

0.6s = 6.6

[divide both sides of the equation by 0.6]

0.6s / 0.6 = 6.6 / 0.6

s = 11

To prove that 11 is correct

[substitute the value of m and s into the equation]

1.80m + 0.6m = 12.00

1.80×(3) + 0.6×(11) = 12.00

5.4 + 6.6 = 12.00

12.00 = 12.00

Tommy and Arnold are playing with water balloons. Arnold is standing by a bush that is 20 feet from where Tommy is standing. Tom
erik [133]

Answer:

The equation that describes the path of the water balloon is:

y =-\frac{1}{10}\cdot (x-10)^{2}+15

Step-by-step explanation:

The motion of the water balloon is represented by quadratic functions. Tommy launches a water balloon from A(x,y) = (0\,ft, 5\,ft) and hits Arnold at B(x,y) = (20\,ft, 5\,ft). Given the property of symmetry of quadratic function, water ballon reaches its maximum at C(x,y) = (10\,ft,15\,ft), which corresponds to the vertex of the standard equation of the parabola, whose form is:

y = a\cdot (x-h)^{2}+k (Eq. 1)

Where:

a - Vertex parameter, measured in \frac{1}{ft}.

h, k - Horizontal and vertical components of the vertex, measured in feet.

x, y - Horizontal and vertical location of the ball, measured in feet.

If we know that x = 0\,ft, y = 5\,ft, h = 10\,ft and k = 15\,ft, the vertex parameter is:

5\,ft = a\cdot (0\,ft-10\,ft)^{2}+15\,ft

a = \frac{5\,ft-15\,ft}{(0\,ft-10\,ft)^{2}}

a = - \frac{1}{10}\,\frac{1}{ft}

The equation that describes the path of the water balloon is:

y =-\frac{1}{10}\cdot (x-10)^{2}+15

Can someone help me 10 points
Elanso [62]

The two angles form a right triangle which is 90 degrees.

Add the two to equal 90:

3x-8 + 4x = 90

simplify:

7x-8 = 90

Add 8 to both sides:

7x = 98

Divide both sides by 7:

x = 14
