Answer:

Since the question requires you to give the answer in terms of steps/minute, the first step would be to convert hours to minutes:

12.5 hours = 750 minutes

Next, if he took 775 steps in 750 minutes, how many would he take in 1 minute?

This requires you to set up the question as a proportion:

(775 steps/ 750 minutes) = (x steps/1 minute)

(1 * 775)/750 = 31/30 = 1.033

he took ~1 step per minute

Write the equation 6561 1/4= 9 in logarithmic form.

Vlad1618 [11]

Answer:

b. log6561(9) = 1/4

Step-by-step explanation:

The relationship between the exponential form and the log form is ...

$b^n=x\\\log_b{(x)}=n$

The exponent is the logarithm. The base is the value the exponent is being applied to.

Here, you have ...

$6561^{\frac{1}{4}}=9$

Comparing this to the form above, we see ...

b = 6561, n = 1/4, x = 9

so the log form of the equation is ...

$\boxed{\log_{6561}{(9)}=\frac{1}{4}}$

This matches choice B.

Find the sum of the first 30 terms of the sequence below an=3n+2

Solnce55 [7]

First off, let's find the 1st term's value, and the 30th term's value,

$\bf a1=3(1)+2\implies a1=5\qquad \qquad \quad a30=3(30)+2\implies a30=92\\\\
-------------------------------\\\\
~~~~~~~\textit{ Sum of an arithmetic sequence}\\\\
S_n=\cfrac{n(a1+an)}{2}~ 
\begin{cases}
n=n^{th}\ term\\
a1=\textit{first term's value}\\
----------\\
a1=5\\
a30=92\\
n=30
\end{cases} \implies S_{30}=\cfrac{30(5+92)}{2}
\\\\\\
S_{30}=15(97)$

1. HELP Use front-end estimation to estimate the sum 8.86 + 9.43 + 5.75

marta [7]

Answer:

1. Option D.

2. Option A.

Step-by-step explanation:

1. You need to follow these steps in order to estimate the sum of $8.86 + 9.43 + 5.75$ :

Step 1: Add the digits in the ones places of the whole numbers (these are: 8, 9 and 5).

Step 2: Round the decimals to the nearest whole number:

$0.86\approx 1\\\\0.43\approx0\\\\0.75\approx1$

Step 3: Add them together:

$8+9+5+1+0+1=8+9+5+2=24$

2. The procedure to estimate the difference of $83.92-47.23$ is:

$83.92-\\47.23\\........\\40.00\\\ -4.00\\\ \ + 0.70\\-0.01\\...........\\+36.00\\+0\ 0.69\\..............\\36.69$

Rounded to the nearest whole number:

$36.69\approx 37$

A bacon cheeseburger at a popular fast food restaurant contains 2,070mg of sodium, which is 86% of the recommended daily amount.

svp [43]

2,070mg 86%
— = —
? mg 100%

Cross multiply (2,070 X 100) which equals 207,000

Then divide 207,000 by 86 which equals
2,406.976

Then you round so you get 2,407

The Answer is 2,407 milligrams
