Answer:

h=39/4

Step-by-step explanation:

area of a triangle = 1/2(b*h)

base = 8 inches

area =39 square inches

input the values given:

39=1/2(8*h)

multiply the right side by 1/2

39=(1/2)8h

find half of 8

39=1/2*8 (h)

hence,

39=4h

divide both sides by 4

hence,

39/4=h

In this situation, As we rise to higher attires, the temperature lowers therefore, only Option B [42. 1º. 40.5º. 39. 70. 34.49. 30.00] follows that requirement.

Answer:

Its Irrational because it does not repeat or terrminate.

Step-by-step explanation:

Rational numbers end, and this one does not not. It also is not a patteren so it dont repeat.

The coordinate point P is at (6, 8) given AB with A(3,-1) and B(8, 14), if p lies on AB such that the ratio of AP to PB is 2:3 is (6, 8)

Midpoint is the point that divides a line into two equal parts.

The formula for calculating the midpoint of a line divided within the ratio a:b is expressed as:

[tex]M(X, Y)=(\frac{ax_1+bx_2}{a+b}, \frac{ay_1+by_2}{a+b} )[/tex]

Given the coordinate point A(3,-1) and B(8, 14) and the ratio 2:3

Get the X coordinate of point P

[tex]X = \frac{2(3)+3(8)}{2+3}\\X=\frac{6+24}{5} \\X = \frac{30}{5}\\X=6[/tex]

Get the Y coordinate of point P

[tex]Y = \frac{2(-1)+3(14)}{2+3}\\Y=\frac{-2+42}{5} \\Y = \frac{40}{5}\\Y=8[/tex]

hence the coordinate point P is at (6, 8)

Answer:

(-3,-10)

Step-by-step explanation:

4 units down means -4 from the y axis

-6 - 4 = -10

Answer:

(m - 7) + 15

Step-by-step explanation:

A difference is the result of a subtraction, so the difference of m and 7 is

m - 7

An increase is obtained by addition, so to increase the difference by 15, add 15 to the difference.

(m - 7) + 15

Answer:

C. 2/3

Step-by-step explanation:

To find the slope of a line from two points, use this formula.

[tex]m=\frac{y^2-y^1}{x^2-x^1}[/tex]

The variable 'm' means slope in algebra.

y² means the second y-coordinate and y^1 means the first y-coordinate.

Based on the previous definition, it should be easy to figure out what x² and x^1 mean.

[tex](2,4),(5,6)[/tex]

[tex]m=\frac{6-4}{5-2} =\frac{2}{3}[/tex]

Therefore, the slope of the line passing through the points (2,4) and (5,6) is 2/3.

Step-by-step explanation:

First, plug in -2 into each y:

3(-2)^2-4(-2)

Simplify 2^2 to 4:

3x4-4x-2

Simplify 3x4 to 12:

12-4x2

Simplify 4 x -2 to get -8:

12-(-8)

Remove parentheses:

12+8

Answer:

k= -14

Step-by-step explanation:

[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} }[/tex]

[tex] \frac{5}{3} = \frac{7 - (3 - k)}{k + 3 - ( - 5)} [/tex]

[tex] \frac{5}{3} = \frac{7 - 3 + k}{k + 3 + 5} [/tex]

[tex] \frac{5}{3} = \frac{4 + k}{k + 8} [/tex]

Cross multiply:

3(4 +k)= 5(k +8)

Expand:

12 +3k= 5k +40

Bring k terms to one side, constant to the other:

5k -3k= 12 -40

Simplify:

2k= -28

Divide both sides by 2:

k= -14

According to the above figure,

RS+ST=RT

Now,

ST=12x

ST=12×2

ST=24

Answer:

Step-by-step explanation:

JK + KL = JL

x² - 4x +3x - 2 = 28

x² - x - 2 = 28

x² - x -2 - 28 = 0

x² - x - 30 = 0

Sum = -1

Product = -30

Factors = -6 , 5    {-6 + 5 = -1 and (-6)*5 = -30}

x²  + 5x - 6x  - 30 = 0   {Rewrite the middle term}

x(x + 5) - 6(x + 5) = 0

(x + 5)(x - 6)= 0

x -6 = 0     {X +5 = 0 is ignored as measurement will not be negative}

x = 6

JK = x² - 4x

     = 6² - 4*6

     = 36 - 24

JK   = 12

KL = 3x -2

    = 3*6 - 2

    = 18 - 2

KL = 16

Step-by-step explanation:

The √(8/2) is equal to 2 if you meant that then the order is 2, 2, 7.

If not then the square root of 8 is approximately 2.82842712475 so divide that by 2 and you get

1.41421356237.

Answer:

RST = 20

Step-by-step explanation:

a ray that divides an angle into two equal angles is called an angle bisector.

So RSP = PST

3 x -2 = 9x - 26

6x = 24

x = 4

RST = 3x -2 + 9x -26 = 20

Answer:

78° and 65°

Step-by-step explanation:

(5)

The 2 angles lie on a straight line and sum to 180° , that is

x + 84 + x + 108 = 180

2x + 192 = 180 ( subtract 192 from both sides )

2x = - 12 ( divide both sides by 2 )

x = - 6

Then

x + 84 = - 6 + 84 = 78°

(6)

the angle opposite 8x is 9x - 7 ( corresponding to the 9x - 7 )

So 8x and 9x - 7are vertical angles and congruent

9x - 7 = 8x ( subtract 8x from both sides )

x - 7 = 0 ( add 7 to both sides )

x = 7

Then

9x - 7 = 9(7) - 7 = 63 - 7 = 56°

Answer:

Jeremy Will have more than just $200 to spend on Christmas presents.

Explanation :

He has a total of $1200.

He spends a $120 for car insurance. (1)

He needs to spend $25 a week for lunch. He has to do this for 16 weeks so 25*16 = $400. (2)

He needs to spend $20 a week for entertainment. For 16 weeks that'll be 20*16 = $320 (3)

adding (1) (2) and (3)

We get Jeremy's total spending will be $840. Jeremy has $1200.

1200-840 = $360

So Jeremy will have $360 to spend on Christmas present.
