. Tina walked 20 miles for a fundraiser. Liawalked m miles. Tina walked 4 times as
far as Lia. Which equation can be used to
find m, the number of miles Lia walked?

Am= 4 x 20
B20 = 4 x m
C20 = m = 4
Dm = 20 + 4

Answers

Answer:

The relation for the distance cover by Tina and Lia is 20 = 4 × m

Option B

Step-by-step explanation

Given as :

The distance cover by Tina = $D_1$ = 20 miles

The distance cover by Lia = $D_2$ = m miles

According to question

Tina walked 4 times as far as Lia

So, The distance cover by Tina = 4 × The distance cover by Lia

Or, $D_1$ = 4 × $D_2$

I.e 20 miles = 4 × m miles

or. 20 = 4 × m

So, relation is 20 = 4 × m

Hence, The relation for the distance cover by Tina and Lia is 20 = 4 × m

Can 2 and 7/12 be simplify

Answers

no because 7/12 is already at it's lowest because 2 doesn't go in to 7 and 2 does go in 12 but u have to simplify it by the same number

1.explain how you could use what you have learned to calculate the height of the leaning tower of pisa on a sunny day. 2.research other real-world situations where triangulation is used. post your findings for your fellow students to see. what questions do you still have about the unit?

Answers

Answer:

1. The slant height of the tower of Pisa is $√(H_v^2 + L_s^2)$

Where:

$H_v$ = Vertical height of the tower of Pisa (Required)

$L_s$ = Length of from the base of the tower to the point where the top is directly up above

2. Calculation of time using the length our shadow

Step-by-step explanation:

1) As the sun is rising, we measure the our shadow and the measure the shadow cast by the leaning side of the tower of Pisa, then we use similar triangles to calculate the vertical height of the tower of Pisa as follows;

$(Our \, Height \, (known))/(Length \, of \, our \, shadow \, (known)) = ( Vertical \, height \, of \, the \, tower \, of \, Pisa \, (Required) \, H_v)/(Length \, of \, the \, shadow \, cast \, by \, the \, slant \, side \, of \, the \, tower \, of \, Pisa, \ L_V)$

$Vertical \, height \, of \, the \, tower \, of \, Pisa \, (Required) \, H_v} = (Our \, Height \, (known) * L_v)/(Length \, of \, our \, shadow \, (known))$

Then, at exactly noon, or when the Sun is directly overhead the tower casting a shadow, we measure the length of the covering from the the base to end of the shadow where the tip is directly up ahead (which can be done by measuring the base of the tower to the point where the top of the tower is directly up above), we call this length $L_s$

Then, the slant height of the tower of Pisa = $√(H_v^2 + L_s^2)$

2. Other real world situation is the calculation of the time of the day using our shadow and triangulation.

Steve buys 14 ounces of kiwis and 2pounds of peaches. How many more ounces do the peaches weigh than the kiwis

Answers

The peaches weigh 18 more ounces than kiwis.

What is unit conversion?

Multiplication or division by a numerical factor, selection of the correct number of significant figures, and unit conversion are all steps in a multi-step procedure.

Given that Steve buys 14 ounces of kiwis and 2 pounds of peaches. The weight will be compared as follows:-

It is known that one pound is equal to 16 ounces.

1pound= 16 ounces

Steve bought two pounds of peaches,

16 x 2= 32

2 pounds = 32 ounces, now subtract that by 14.

32 - 14 = 18 Ounces

Therefore, the peaches weigh 18 more ounces than kiwis.

To know more about unit conversion follow

#SPJ2

Hey There!

1pound= 16 ounces

Steve bought two pounds of peaches, 16 * 2= 32

So, 2 pounds = 32 ounces, now subtract that by 14.

In conclusion, the peaches weigh 18 more ounces than kiwis.

If every positive number has two square roots and you can find the length of the side of a square window by finding a square root of the area, why isthere only one answer for the length of a side?

Answers

because the 2 square roots are positive and negative
ex
squareroot of 4=2 or -2 since 2 time2=4 and -2 times -2=4
we normally use the principal root or the positive root since legnth in real life cannot be negative

you cannot have a window that is -5 inches long
