pls answer this but dont take my points if your not gonna answer it correctly or atleast a smart answer

Answer:

1.75 10^-15 scientific notation

Step-by-step explanation:

(2.5×10^−10 = 0.00000000025) *  (7 ×10^−6 = 0.000007 ) =1.75 10^-15 = 0.0000000000000015 we just count 15 zeros from decimal at 1.5 back 15 spaces place the decimal and add another zero in front of the decimal or do the multiplication 2.5* 7 = 1.75   and 1.75 *100 (^-10 -^6 ) =1.75 *100 --^16 -10 shown fro the 100 preceding  = .75 *100 --^16 -10  = .75 *100 --^15 or just do 0.000007 * 0.00000000025 = 0.0000000000000015  as -700 * -25 = 17500 and as this is moved (a to b) by 4 places we can place decimal back 4 places to get 0.0000000000000015   decimal notation

Answer:

1 322 000 000 km OR 1.322 x \(10^{9}\) km

Step-by-step explanation:

step 1: convert the Venus value to a normal number which means multiplying it by doing 8 'hops' to the right to make it bigger:

= 108 000 000

step 2: convert the Saturn value into a normal number:

= 1 430 000 000

step 3: subtract them!

= 1 430 000 000 - 108 000 000

= 1 322 000 000 km

(if they want it in standard form it would be 1.322 x \(10^{9}\) km)

First answer :D

Answer:

x = 5

Step-by-step explanation:

Now to solve for our equation:

110 - 4x = 130 - 8x

Subtract 110 from both sides: (110 - 110) - 4x = (130 - 110) - 8x

Simplify: -4x = -8x + 20

Add 8x to both sides: (-4x + 8x) = (-8x + 8x) + 20

Simplify: 4x = 20

Divide both sides by 4: (4x / 4) = (20 / 4)

Simplify: x = 5

Answer:

A rhombus.

Step-by-step explanation:

Geometry for me is easy

Also have a good day

Answer:

A rhombus.

Step-by-step explanation:

I did this at school TODAY, trust me!

Answer:

(10t + u)(10u + t) = 4,930

100tu + 10t^2 + 10u^2 + tu = 4,930

101tu + 10t^2 + 10u^2 = 4,930

10t^2 + (101u)t + (10u^2 - 4,930) = 0

(101u)^2 - 4(10)(10u^2 - 4,930)

= 10,201u^2 - 400u^2 + 197,200

= 9,801u^2 + 197,200

We see that u = 5 gives 442,225.

√442,225 = 665

(10t + 5)(50 + t) = 4,930

500t + 10t^2 + 250 + 5t = 4,930

10t^2 + 505t - 4,680 = 0

2t^2 + 101t - 936 = 0

t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)

= (-101 + √17,689)/4

= (-101 + 133)/4 = 32/4 = 8

So the numbers are 58 and 85.

58 + 85 = 143

Answer: $0.35

Step-by-step explanation:

Answer: 7%

Step-by-step explanation:

Ok, we'll start by listing the facts.

Facts

Pack of pencils is $5

Total cost: 5.35

This means the sales tax is 35 cents, but we need to find the percentage to get the sales tax rate.

We can do this by dividing .35 by 5

0.35÷5= 0.07

Convert 0.07 to a percentage by multiplying it by 100

0.07x100= 7

Hence the sales tax rate is 7%. We can check to make sure this is correct by finding 7% of 5, and then adding the result to the 5.

7% of 5= 0.35

5+0.35= 5.35

Hope this helps, and brainliest would be appreciated :))

Answer:

it cost 5.25 because if u divide 31.50 by 6 it gives u that

Answer:

$5.25

Explanation:

$31.50/6 = $5.25

Answer: Model B

Step-by-step explanation: Model B, shows the cutting of 40%  of the ribbon since, if you divide it into 10 parts, with each piece representing 10%, if you take away 4 of those parts, which is equal to 40%. So it is Model B.

Answer:

5b+10

Step-by-step explanation:

This can be solved using the distributive property. You multiply 5 by b to get 5b, and then 5 by 2 to get 10. This then gives you 5b+10

Explanation:

The data from the stem-and-leaf plot is:

10,

24,25,26,

30,30,32,33,

40,45,46

Add up those values

10+24+25+26+30+30+32+33+40+45+46 = 341

Then divide over n = 11 which is the sample size.

341/11 = 31 is the arithmetic mean.

Answer:

341/11 = 31 is the arithmetic mean.

Answer:

PR = 25 cm

SR = 27.73 cm

Step-by-step explanation:

PSR and PQR are right triangles.

First, you can find PR using the Pythagorean theorem.

\(PR = \sqrt{24^2+7^2} =\sqrt{625} = 25 cm\)

Now let's do the same thing for the other triangle:

\(SR=\sqrt{25^2+12^2} =\sqrt{769} = 27,73 cm\)
