Julio runs 4 miles each time that he goes running. If he goes running 7 times a week, how many miles does he run total in one week?

Answers

Answer:

He runs 28 Miles every week!

Step-by-step explanation:

(The week is 7 days long)

1st DAY = 4M

2nd DAY = 4M

3rd DAY = 4M

4th DAY = 4M

5th DAY = 4M

6th DAY = 4M

7th DAY = 4M

(The M next to the 4 means miles you don't have to include it in your answer on your homework!)

4 + 4 + 4 + 4 + 4 + 4 + 4 = 28

OR

4 x 7 = 28

A factory manufactures 9 x 10^5 packs of gum each month. They send these out to 16 different distribution centers. If each distribution center gets the same number of packs, how many are sent to each center?

Answers

Answer:

The answer would be A.

Step-by-step explanation:

You would take 9 x 10^5 = 900000 and divide that by 16 to get 56250.

After that, you move the decimal over by 4 to make it a number with only one number above zero in front of the decimal to make 5.625 (negate the 0 bc it does not mean anything after you moved the decimal over)

Since you moved it over by four places, the exponent next to the 10 will be 4, making the final answer 5.625 x 10^4

Good luck and hope this helps!!

Quadrilateral ABCD has vertices A(- 3, 1), B(4, 2) B(4, 2), C(9, - 3) , and D(2, - 4) . aProve that quadrilateral ABCD is a rhombus b )Prove that ABCD is not a square .

Answers

9514 1404 393

Explanation:

The vectors representing the diagonals are ...

  AC = C - A = (9, -3) -(-3, 1) = (12, -4)

  BD = D - B = (2, -4) -(4, 2) = (-2, -6)

The dot-product of these vectors is the sum of the products of corresponding coordinates:

  (12)(-2) +(-4)(-6) = -24 +24 = 0

When the dot-product is zero, the vectors are perpendicular. These vectors are different lengths (BD = 1/2·AC), so they are not the diagonals of a square.

__

The midpoints of the diagonals will be in the same place if the quadrilateral is a rhombus.

  (A +C)/2 = (B +D)/2

We can simplify our effort a bit by multiplying by 2.

  A+C = B+D

  (9, -3) +(-3, 1) = (2, -4) +(4, 2)

  (6, -2) = (6, -2) . . . . . . . . . . . . . . . . yes, the midpoints are the same point

__

We have shown the diagonals of the quadrilateral are different lengths and perpendicular bisectors of each other, so the quadrilateral IS A RHOMBUS, NOT A SQUARE.

The ratio of potatoes to onions is 1:2 respectively if there are 14 onions how many photatoes are there

Answers

If there are 14 onions there will be7 potatoes

Answer:

7

Step-by-step explanation:

The ratio of potatoes to onions is 1:2, meaning there are twice as many onions as potatoes.

[tex]\frac{\text{potatoes}}{\text{onions}}=\frac{1}{2}=\frac{x}{14}[/tex]

The fraction on the right is equivalent to 1/2, so the numerator is half the denominator.  There are 7 potatoes.

Brett has 100 feet of fence with which to make a rectangular cage for his dog. The area of the cage in square feet is given by the polynomial where w is the width of the cage in feet. What is the area of the cage if the width is 8 feet?

Answers

Answer:

Area of rectangle cage = 336 feet²

Step-by-step explanation:

Given:

Wire required for fencing = 100 feet

Width of rectangular cage = 8 feet

Find:

Area of rectangle cage

Computation:

Wire required for fencing = perimeter of cage

Perimeter of rectangular cage = 100 feet

2[l + b] = 100 feet

l + 8 = 50 feet

Length of rectangular cage = 42 feet

Area of rectangle cage = Length x Width

Area of rectangle cage = 42 x 8

Area of rectangle cage = 336 feet²

What does the 49 days until Fourth of July there are seven days in a week and how many weeks will it be Fourth of July

Answers

Answer:

It will be Fourth of July in 7 weeks.

Step-by-step explanation:

Since you know that there are seven days in a week, you can use a rule of three to find the amount of weeks in 49 days that is the number of days until Fourth of July:

 7 days    →    1 week

49 days    →        x

x=(49*1)/7

x=7

According to this, the answer is that it will be Fourth of July in 7 weeks.

solve the triangle give the measure of y

Answers

Given:

In triangle [tex]BGU,BG=x,GU=7,BU=y,m\angle U=90^\circ,m\angle B=44^\circ[/tex].

To find:

The value of y.

Solution:

In a right angle triangle,

[tex]\tan \theta=\dfrac{Perpendicular}{Base}[/tex]

In triangle BGU,

[tex]\tan B=\dfrac{GU}{BU}[/tex]

[tex]\tan 44^\circ=\dfrac{7}{y}[/tex]

[tex]0.966=\dfrac{7}{y}[/tex]

Isolating y, we get

[tex]y=\dfrac{7}{0.966}[/tex]

[tex]y=7.2463[/tex]

[tex]y\approx 7.2[/tex]

Therefore, the correct option is A.

Geoffrey incorrectly found the margin of error because he used the wrong sample size. Therefore, the correct option is option B.

What is mathematical error?

Measurement Error is the difference between the approximated value and the actual value of an object/quantity. The relative error can be computed in the percent with the help of relative error formula. Errors in measuring instruments occur due to inescapable faults in the measuring instrument and limitations of the human eye.

There are three types of errors in solving mathematics problems, which are factual error, procedural error, and computational error. Geoffrey incorrectly found the margin of error because he used the wrong sample size.

Therefore, the correct option is option B.
