Answer:

4617000000

Step-by-step explanation:

10^9 = 1000000000

1000000000 x 4.6 = 4600000000

10^7 = 10000000

10000000 x 1.7 = 17000000

4600000000 + 17000000 = 4617000000

Every week, Enrique walks one mile each day for 4 days of the week. He can usually walk one mile in about 14-16 minutes. Estimat

Phantasy [73]

Answer:

480 miles

Equation:

$t=60w, w=number \ of \ week, t=time \ in \ minutes.$

Step-by-step explanation:

#First we calculate the average time it takes to walk one mile:

$\bar x=\frac{1}{n}\sum(x_i)}\\\\=\frac{1}{2}(14+16)\\\\=15\ min$

#We then calculate the number of miles he walks in 8 weeks.

-Given he walks one mile per day, 4 times a week;

$Total \ Distance=4\times 1\times 8\\\\=32\ miles$

#Multiply the distance traveled by the average time per mile to get total time spent:

$t=miles\times min/mile\\\\=15\times 32\\\\=480\ minutes$

Hence, the walking time over the 8 period will be 480 minutes

#This can be represent as:

Let w be the number of weeks and t be the time in minutes.

The time spent on walking per week is $4\times 15=60\ minutes$

Therefore the time spent walking in w weeks is represented as:

$t=60w, w=number \ of \ week, t=time \ in \ minutes.$

A store owner spends 7x + 13 dollars on two orders of boxes of light bulbs, including shipping.

Alex Ar [27]

Answer:

$B = 4x + 8$

A box = $11

Step-by-step explanation:

Given

$Total = 7x + 13$

Represent the first order with A and the second with B.

So, we have:

$A = 3x + 5$

Solving (a): Find B.

To find B, we make use of:

$A + B = Total$

Make B the subject

$B = Total - A$

Substitute values for Total and A

$B = 7x + 13 - (3x + 5)$

Open bracket

$B = 7x + 13 - 3x - 5$

Collect Like Terms

$B = 7x - 3x + 13 - 5$

$B = 4x + 8$

Solving (b): Cost of a box of light bulb

This means that:

$Total = 90$

Substitute 7x + 13 for Total

$7x + 13 = 90$

Collect Like Terms

$7x = 90 - 13$

$7x = 77$

Make x the subject

$x = \frac{77}{7}$

$x = 11$

Which input value produces the same output value for the two functions

Lady bird [3.3K]

Answer:

Completion to the first table for $f(x)=\frac{2}{3} x+7$ is {-1, 1, 3, 5}

Completion to the second table for $g(x)=2x+16\\$ is { -8, -2, 4, 10}

the option is x=-6

Step-by-step explanation:

$\frac{2}{3} (-12)+7= -1$

$\frac{2}{3} (-9)+7=1$

$\frac{2}{3} (-6)+7=3$

$\frac{2}{3} (-3)+7=5$

$2(-12)+16=-8$

$2(-9)+16=-2$

$2(-6)+16=4$

$2(-3)+16=10$

Hope this helps and is correct.

A craftsman makes a circular table with a radius of 55

Rudik [331]

Answer:

Hey mate here is your answer...

Step-by-step explanation:

smaller circular table to be made

with a diameter only half as big... and diameter of big table is (2*55)= 110cm.... So half diameter of big is (110/2)= 55cm

therefore, diameter of smaller table is 55cm and radius of it's (55/2)= 27.5cm

circumference of circle = 2πr

= 2*3.14*27.5

= 172.7 cm = 27.5cm

hope it helps you ❣️
