Answers

Answer 1

Answer:

Answer: 34,651

Step-by-step explanation:

Given number : 42,780

Here the place value of 4 is 40,000 or 4 ten thousand.

Let's check all the optins for the right answer.

The value of 4 in 34,651 is 4,000 or 4 thousand

and $40,000=10*4,000$

Thus, 34,651 is the number in which the value of 4 is 10 times the value of 4 in 42,780.

Rest of the options are incorrect.

Answer 2

Answer: 146,703 because the 4 is both in the same place, in the ten thousands place.

HEY GUYS PLEASE HELP ME ANYONE I MEAN ANYONE WHOO EXPLAINS WELL AND NOT FOR THE POINTS WILL BE MARKED AS BRAINLIEST .SOLVE EACH SYSTEM BY SUBSTITUTION SO WE HAVE -4X+6Y=12X+2Y=-10 SO FAR I GOT -14Y=52 DONT GET ME WONG I KNOW HOW TO SOLVE IT BUT SINCE 14 GOES INTO 52 3 TIMES DO I THEN HAVE TO PLUG IN FOR Y

Answers

-4x + 6y = 12
x + 2y = -10

First solve for x in the second equation

x + 2y = -10
x = -10 - 2y

Now we have a value for x so we can substitute it into the other equation

-4 (-10 - 2y) + 6y = 12

Now solve for y

40 + 8y + 6y = 12
40 + 14y = 12
14y = -28
y = -2

Now we have a value for y that we can plug into one of the original equations so we can solve for x

x + 2y = -10
x + 2(-2) = -10
x - 4 = -10
x = -6

Your solution set is

(-6, -2)

If (x) = x / x^2-16 what is the value of f(-10)

Answers

The value of the f(-10) is -5/42

We have given that,

$f (x) = x / x^2-16$

We have to determine the value of the f(-10)

We just replace the value of x by -10 therefore we get,

What is the function?

A function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function. Functions were originally the idealization of how a varying quantity depends on another quantity.

Therefore we get,

$f(-10)=(-10)/((-10)^2-16)$

$f(-10)=(-10)/(100-16) \nf(-10)=-(5)/(42)$

Therefore the value of the f(-10) is -5/42.

Answer:

$f(-10)=-(5)/(42)$

Step-by-step explanation:

You just replace 'x' for the value given, -10.

$f(x)=(x)/(x^2-16)\n\n\nf(-10)=(-10)/((-10)^2-16)=(-10)/(100-16)=(-10)/(84)\n\n\n\n\nf(-10)=-(5)/(42)$

Jerome added two numbers.The sum was 83.One of the numbers was 45.What was the other number?

Answers

To know the second number we should 83 - 45 and we get 38. Now we need to check the result.
45 +38, we'll get 83.
So the answer is correct.

83 - 45 = 38

The answer is 38.

A fruit salad consists of blueberries,raspberries,grapes,and cherries. The fruit salad has a total of 280 pieces of fruit. There are twice as many raspberries as blueberries, three times as many grapes as cherries, and four times as many cherries as raspberries. How many cherries are there in the fruit salad?

Answers

Answer=64 cherries

raspberries:blueberries:grapes:cherries
a ratio where b=blueberries can be made....
2b:b:3(4(2b)):4(2b)
2b:b:24b:8b
substitute b for 1
raspberries:blueberries:grapes:cherries
2:1:24:8

2+1+24+8=35
280/35=8
8*2=16 raspberries
8*1=8blueberries
8*24=192grapes

A circle with a radius of 4 in, is dilated by a scale factor of 5. What will be the circumference of the circle after dilation?21 in
4 in
161 in
24 in

Answers

Ok so circumference=2*pi*radius. So We know that the radius is dilated by a scale factor of 5, so we can put 2*pi*20. For pi you can use So when we multiply 2*pi*20, you get 125.6637
