Answer:

6.24

Step-by-step explanation:

The formula for finding the area of a triangle is A = 1/2 b x h, (A meaning area, B meaning the base of the triangle, and H meaning the height of the triangle.)  Plug in the values for the formula and you get A = 1/2 (4.8) x (2.6)  Multiply 4.8 and 2.6 to get 12.48.  1/2 of 12.48 is 6.24, so that is the answer.  

Sorry if I'm wrong, but I hoped this helped!  :)

Answer:

C, D

Step-by-step explanation:

Answer is in the photo below.

Slope= 0.1

Step-by-step explanation:

Given:

The boundary line of an inequality is:

[tex]2x+3y=6[/tex]

The solution set contains (0,0).

To find:

The inequality.

Solution:

The boundary line of an inequality is

[tex]2x+3y=6[/tex]

Since (0,0) is in the solution set, therefore (0,0) satisfies the required inequality.

Taking LHS, we get

[tex]LHS=2x+3y[/tex]

Substitute x=0 and y=0.

[tex]LHS=2(0)+3(0)[/tex]

[tex]LHS=0+0[/tex]

[tex]LHS=0[/tex]

The right hand side of the given equation is 6.

[tex]RHS=6[/tex]

We know that,

[tex]0<6[/tex]

[tex]LHS<RHS[/tex]

[tex]2x+3y<6[/tex]

The boundary line is not a dotted line, it means the points on the boundary line are also included in the solution set. So, the inequality sign must be [tex]\leq [/tex].

[tex]2x+3y\leq 6[/tex]

Therefore, the required inequality is [tex]2x+3y\leq 6[/tex].

Answer:

its 3 inches

Step-by-step explanation:

Because 9 divided by 3 is 3 (in.) as well as 6 divided by 2 and if its equilateral, all sides are the same (i hope this makes sense)

Answer:

3 inches because you split the 2 bottomed ones 3 in for both 6

Answer:

Since area =7.7

[tex]area = \frac{22}{7} {(r)}^{2} \\ {(r)}^{2} = 2.45 \\ r = 1.57[/tex]

Answer:

x = 7

Step-by-step explanation:

4x - 9 = 2x +5        add 9 from both sides

4x = 2x +14            subtract 2x from both sides

2x = 14.                   divide both sides by 2

x = 7

Answer:

x = 7

Step-by-step explanation:

Rewrite equation

4x - 9 = 2x + 5

Add 9 on both sides

4x -9 +9 = 2x + 5 + 9

Simplify

4x = 2x + 14

Subtract 2x on both sides

4x - 2x = 2x + 14 - 2x

2x = 14

Finally divide both sides by 2

2x/2 = 14/2

x = 7

The values of [tex]x[/tex] that solve the equation [tex]f(x) = g(x)[/tex] are 0, 0.256 and 2.285, respectively.

In this question we must look for all points where each curve intersects each other. By direct inspection on figure given, we conclude that [tex]f(x) = g(x)[/tex] happens in thrice: (i) [tex](x,y) = (0, 0)[/tex], (ii) [tex](x,y) = (0.256, 0.505)[/tex], (iii) [tex](x,y) = (2.285, 1.512)[/tex]

Hence, the values of [tex]x[/tex] that solve the equation [tex]f(x) = g(x)[/tex] are 0, 0.256 and 2.285, respectively.

Answer:

the total cost is $86.40

Answer:

The cost of producing 60 t-shirts is $495.

36 t-shirts will let the cost, C(x) = 303

Step-by-step explanation:

If we producing 60 t-shirts, then we plug in 60 for the x, which x represents t-shirts for the marching band.

C(x) = 8x + 15

C(x) = 8(60) + 15

C(x) = 480 + 15

C(x) = 495

If the cost of the t-shirts is 303, we plug in 303 for the cost,C(x).

C(x) = 8x + 15

303 = 8x + 15

288 = 8x

x = 36
