Find the three arithmetic means in this sequence. 12 __ __ __ 40

Lena [83]

To answer this question first you have to count the difference between the highest number with the lowest number.
In this case, the difference is: 40-12=28

After that, you need to determine the leaps in the sequence. In this case, there are 4 leaps.
After that divide the difference with the leaps : 28:4=7
Therefore the sequence will be 12 , 19, 26, 33, 40

One number is eight less than a second number. Twice the first is 12 more than 4 times the second. Find the numbers.

tia_tia [17]

Answer:

Step-by-step explanation:

"One number is eight less than a second number."

x = y-8

"Twice the first is 12 more than 4 times the second."

2x = 4y+12

substitution

2(y-8) = 4y + 12

2y - 16 = 4y + 12

2y = -28

y = -14

x = y-8 = -22

Gold has a density of 19.3 g/cm3 , it is often made into a bar called a gold ingot. A certain gold ingot has a volume 51.8 cm

kkurt [141]

The gold ingot would be 999.74 grams. if one centimeter cubed has a mass of 19.3, then 51.8 centimeters cubed would have a mass of 999.74 grams.

The height of a triangle is 4 inches greater than twice its base. The area of the triangle is no more than 168 in.² which inequa

Gennadij [26K]

<h2>Answer:</h2>

Correct option: B

<h2>Step-by-step explanation:</h2>

When we say a is no more than b, we express this in a mathematical language as follows:

$a\leq b$

In this inequality, we know that the area of the triangle is no more than 168 in². In other words, if the area is named $A$ , then:

$\mathbf{(1)} \ A\leq 168$

We also know that the height of a triangle is 4 inches greater than twice its base. Translating this in a mathematical language:

$\mathbf{(2)} \ h=2b+4 \\ \\ h:height \ of \ the \ triangle \\ \\ b:base \ of \ the \ triangle$

From geometry, we know that the area of a triangle is given by:

$\mathbf{(3)} \ A=\frac{bh}{2}$

Matching (1), (2) and (3):

$\frac{bh}{2}\leq 168$

Since the length of the base of the triangle is $x$ , then $b=x$

$\frac{x(2x+4)}{2}\leq 168 \\ \\ Common \ factor \ 2: \\ \\ \frac{2x(x+2)}{2}\leq 168 \\ \\ \boxed{x(x+2)\leq 168}$

Finally, correct option is B.
