A certain number was multiplied by 7. 4 was taken away from the product. Finally, that difference was then divided by 9, resulti
marin [14]

Answer:

7

Step-by-step explanation:

To solve this, we have to work backwards. If you divide something by 9, and it equals 5, to figure out the number, we need to multiply by 9. 5*9= 45. If four was taken away, we have to add it to 45, which is 49. If a number *7 is 49, then we have to divide by 7 to get the answer. 49/7=7

The following conditional statement true. what is the statements converse and is the converse true?
Lera25 [3.4K]
A converse is when we switch the hypothesis and conclusion, so "if a figure is a square then it has four right angles" the converse would be "If a figure has four right angles then it is a square" Which is false because of rectangles, your answer is D.

Inscribed angles math lib <br> Need help with 9 and 10 thank you!!
telo118 [61]

Answer:

54° and 110°

Step-by-step explanation:

The opposite angles of a cyclic quadrilateral are supplementary, sum to 180°

(9)

19x - 26 + 7x - 2 = 180

26x - 28 = 180 ( add 28 to both sides )

26x = 208 ( divide both sides by 26 )

x = 8

Then

∠ EFG = 7x - 2 = 7(8) - 2 = 56 - 2 = 54°

(10)

21x - 33 + 14x + 3 = 180

35x - 30 = 180 ( add 30 to both sides )

35x = 210 ( divide both sides by 35 )

x = 6

Then

∠ YVW = 14x + 3 = 14(6) + 3 = 84 + 3 = 87°

The inscribed angle YVW is half the measure of its intercepted arc YW, so

arc YW = 2 × 87° = 174°, then

arc XW = 174° - 64° = 110°

I had a question ask how many years will it be until 80% of the population will be registered to vote. the answer is t=10.14 but
Pachacha [2.7K]

Answer:

This is what came up when I googled it... Sry

Step-by-step explanation:

e^{\ln x}=x

\ln = natural logarithm

e = natural exponent

x = real number

The "common" logarithm has 10 as its base and is denoted as “log.” The following formula allows you to take the natural logarithm by using the base-10 logarithm: ln(number) = log(number) ÷ log(2.71828).
