Area of triangle = 0.5 base height

24 = 0.5 x 6 height

height = 8 inches

Answer: 8inches

Step-by-step explanation:

First we have to know the formula for the area of a triangle

A = (1/2)bh

Where

b = base

h = height

That's half of the base multiplied by the height

Are now we make the height the subject of formula since that's what we are looking for

Multiply both sides by 2

2A = 2((1/2)bh) =bh

divided both sides by b

2A/b = h

h = 2A/b

So we both the value of the A and b in the equation

h = 2(24)/6 = 2(4) = 8inches

Mark and Don are planning to sell each other their marble collections at a garage sale. If Don has 1 more than 3 times the numbe

Volgvan

Answer: Mark has 28 marbles while Don has 85 marbles.

Step-by-step explanation:

Let x represent the number of marbles that Mark has.

Let y represent the number of marbles that Don has.

If Don has 1 more than 3 times the number of marbles Mark has, it means that

y = 3x + 1

The total number of marbles is 113. It means that

x + y = 113- - - - - - - - - - - - 1

Substituting y = 3x + 1 into equation 1, it becomes

x + 3x + 1 = 113

4x + 1 = 113

4x = 113 - 1 = 112

x = 112/4

x = 28

y = 3x + 1 = 3 × 28 + 1

y = 85

The middle number of 3 consecutive whole numbers is 2a.

TiliK225 [7]

First number --- (2a-1)
middle number ---- (2a)
third number -----(2a+1)
2a-1+2a+2a+1=250
6a=250
a=250/6= 125/3
2a=2*(125/3)= 250/3 ---- is not a whole number that is contradicts to what is given, so sum cannot be 250

Find the seventh term of the sequence which has a first term of 1/2 and has a common ratio of three

prohojiy [21]

The seventh term of the sequence is 364.5

<h3>Geometric progression </h3>

From the question, we are to determine the seventh term of the sequence

Using the formula,

$a_{n} = ar^{n-1}$

Where $a_{n}$ is the nth term

a is the first term

and r is the common ratio

From the given information,

a = 1/2

r = 3

Thus,

$a_{7} = (\frac{1}{2}) 3^{7-1}$

$a_{7} = (\frac{1}{2}) 3^{6}$

$a_{7} = \frac{1}{2} \times 729$

$a_{7} = 364\frac{1}{2} \ OR \ 364.5$

Hence, the seventh term of the sequence is 364.5
