34,258 and 47,163 The value of 4 in------ is ----- times The value of 4 in -------

1 answer:

6 0

The value of 4 in 47,163 is 10 times greater than the value of 4 in 34,258.

Each time you move one place over (e.g. tens to hundreds) the number gets 10 times larger if you move to the left and 10 times smaller if you move to the right. So, for example you go from tens to hundreds it is 10 times larger, but if you go from hundreds to tens then it is 10 times smaller.

Jack and Jill start driving from the same location. Jack drives 30 miles south while Jill drives west. If Jack and Jill are 78 m

arsen [322]

Answer:

72 mles

Step-by-step explanation:

For better understanding, I'll make use of an attachment.

From the attachment,

O represents the start point

$OB = 30$ --- Jack

$AB = 78$ -- Distance between them

Required

Find OA; Jack's distance

To do this, we make use of Pythagoras theorem

$AB^2 = OA^2 + OB^2$

This gives:

$78^2 = OA^2 + 30^2$

$6084 = OA^2 + 900$

Subtract 900 from both sides

$OA^2= 6084 - 900$

$OA^2= 5184$

Take square roots

$OA = \sqrt{5184}$

$OA = 72$

Hence, Jill drove 72 miles

Solve for q. a=qb+r What is q equal to? q=a−r−b q=a−r/b q=a/b−r q=a/rb

avanturin [10]

The given equation is $a=qb+r$

We need to solve the equation for q.

Value of q:

Let us determine the value of q from the equation $a=qb+r$

Subtracting both sides of the equation by r, we get;

$a-r=qb$

Now, dividing both sides of the equation by b, we have;

$\frac{a-r}{b}=\frac{qb}{b}$

Simplifying the terms, we get;

$\frac{a-r}{b}=q$

Therefore, the value of q is $q=\frac{a-r}{b}$

Hence, Option B is the correct answer.

Don't guess!

Alisiya [41]

Answer:

I believe the answer is B.

Step-by-step explanation:

The questions says for every 1 hour she reads a book, she reads 0.25 hours with a magazine. Answer B says 2 hours for book, meaning that you wouldn’t have 0.25, you would have 0.5. So for books, you’d go up every 2 hours, and for magazines, you’d continue going up in half’s!

im sorry if this is wrong, but I hope that helped if it’s correct!

(also sorry if the explanation didn’t make any sense)
