48 POINTS PLEASE HELPPPPPPP....The formula for the area of a traingle is 1/2 bh, where b is the length of base of the traingle and h is the vertical height. Use the formula to find the height of a traingle with a base length of 8 inches and an area of 39 square inches.​

Answers

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

Answers

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.

        Now show why there are other possibilities wrong

Option A increases with the altitude, which violets the particular condition.Option C again increases at this temperature as the altitude increases and abruptly falls to 20, which is not our condition.option D up to 51.8 sounds excellent, however, this is achievable as is our given situation but the temperature goes to 59.3, therefore, this option is also refused.

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, find the coordinates of P.

Answers

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)

Select the choice that translates the following verbal phrase correctly to algebra:

the difference of m and 7 increased by 15

Options:

7m + 15


(m − 7) + 15


m − 7 ÷ 15

Answers

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

What is the slope of the line passing through the points (2, 4) and (5, 6)?

Answers

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.

Find the value of k such that the line through (k+3,7) and (-5,3 – k) has a

Answers

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:

Point K is between points J and L. If JK=x2−4x, KL=3x−2, and JL=28, find JK and KL.

Answers

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

Which equation can be used to solve for x in the following diagram

Answers

Answer:

C. (3x + 12) + x = 180

Step-by-step explanation:

[tex](3x + 12) \degree + x \degree = 180 \degree \\ \{angles \: on \: straight \: line \} [/tex]

group like terms together:

[tex](3x + x) + 12 = 180 \\ 4x = 180 - 12 \\ 4x = 168 \\ x = 42[/tex]

equation C would be your answer.

(3x + 12) and x represent 180 combined.

so (3x + 12) + x = 180, combine your like terms which is your x, x + 3x = 4x

4x + 12 = 180 (subtract 12 on both sides)
-12 -12
————————
4x = 168 (divide 4 on both sides)
—- ——
4 4

x = 42

to check your answer you replace the x with 42 and you should get 180 as your answer

(3x+12) = 180
3(42)+12 = 180
126 + 12 = 138

x = 42

138 + 42 = 180

Step-by-step explanation:

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

x = 4

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

the 1st, 5th and 10th terms of a linear sequence are GP. if the sum of the 2nd and 8th term of the linear sequence is 30 find the first term

Answers

Answer:

12 or 15

Step-by-step explanation:

Let the first term is a and common difference is d.

Given:

a, a₅ and a₁₀ form a GP ⇒ a₅/a = a₁₀/a₅a₂ + a₈ = 30a = ?

Use the equation of nth term:

a₅ = a + 4da₁₀ = a + 9da₂ = a + da₈ = a + 7d

According to the given we have:

(a + 4d)² = a(a + 9d) a² + 8ad + 16d² = a² + 9ad16d² = add(16d - a) = 01. d = 0

or

2. a = 16d

Now, use the equation of sum:

a + d + a + 7d = 302a + 8d = 30a + 4d = 15a = 15 - 4d

Compare the value of a and find d:

1. d = 0

a = 15 - 4*0 = 15, in this case all the terms are same

2. a = 16d

15 - 4d = 16d20d = 15d = 15/20d = 0.75

Find a:

a = 16*0.75a = 12

Answers

Answer:

See THE IMAGE FOR SOLUTION

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°

Jeremy has $1200 in spending money for the fall semester of college. He needs to purchase car insurance at $120 for 4 months, $25 a week to buy his lunch in the cafeteria every day, and $20 bi weekly for entertainment. If the semester is 16 weeks long, will Jeremy have $200 to spend on Christmas presents for his family? Explain

Answers

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.
