Answer:

2,110

Step-by-step explanation:

5 • [(14 + 3 • 30) + 120] + 10³ – 10

The dot means multiplication

The we can use the order of BODMAS

First is open the brackets

5 • [(14 + 3 • 30) + 120] + 10³ – 10

5 • [(14 + 90) + 120] + 10³ – 10

5 • [104 + 120] + 10³ – 10

5 • 224 + 10³ – 10

1,120 + 10³ – 10

1,120 + 1000 - 10

2,120 - 10

It’s asking for LATERAL surface area btw

lozanna [386]

Answer:

Lateral surface area = 826.5 m²

Step-by-step explanation:

Formula to calculate the lateral surface area of the triangular prism,

Lateral surface area of the triangular prism = Perimeter of the triangular base × Height

Perimeter of the triangular base = 6 + 11 + 12

= 29 m²

Height of the prism = 28.5 m

Therefore, lateral surface area of the prism = 29 × 28.5

= 826.5 m²

George observes that for every increase of 1 in the value of x, there is a increase of 60 in the corresponding value of y. He cl

Hi there!

FACTS :

To see if multiple ratios are proportional, you can write them as fractions, reduce them, and compare them. If the reduced fractions are all the same, then you have proportionnal ratios. You can also write them as fractions and divide the numerator (top number) by its denominator (bottom number), and compare the decimal numbers the same way you would compare the fractions (I personnaly find this method easier because you don't need to simplify the fractions).

STEPS TO ANSWER:

x = 1 ; y = 90 → $\frac{1}{90} =$ 1 ÷ 90 = 0.01111111...

x = 2 ; y = 150 → $\frac{2}{150} =$ 2 ÷ 150 = 0.0133333...

x = 3 ; y = 210 → $\frac{3}{210} =$ 3 ÷ 210 = 0.01428571

x = 4 ; y = 270 → $\frac{4}{270} =$ 4 ÷ 270 = 0.0148148...

x = 5 ; y = 330 → $\frac{5}{330} =$ 5 ÷ 330 = 0.01515152

** You didn't really need to calculate them all because even the first two decimal numbers weren't equivalent, but I wanted to show you the whole process so I calculated them all.

⇒ If you compare all the decimals you got, you can easily see that they are not the same, which means that the ratios between the values of "x" and the values of "y" are not proportional. Therefore, George's reasoning wasn't good.

There you go! I really hope this helped, if there's anything just let me know! :)

If number A is a 2-digit number and its digits are transposed to form number B, then the difference between the larger of the tw

galben [10]

If the original number is ab it has a value of

10a+b when it is reversed it will have a value of 10b-a

10b+a-10a-b is the differences which is equal to

9b-9a

So the numbers must be divisible by 9

Please help!!!!!!!!!

Natali [406]

Answer: $432

Step-by-step explanation: If he marks up the price by 80% then you multiply the price (240) times 0.8, which is 192. That is how much he marks it up -- $192. SO then you add how much he marks it up to the original price of $242 which is $432.
