Answer:

Step-by-step explanation:

There are a couple of ways you could solve this problem. B is one of them.

The correct answer is going to be Small hypotenuse / Large hypotenuse = tree / building height

Let the tree equal x

100/220 = x / 176 Multiply both sides by 176

100 * 176 / 220 = x

x = 80

Notice that 80 is almost 1/2 of 176 so the answer should be right since 100 is nearly 1/2 of 220

You are testing two scales for accuracy by weighing two different objects. Use the drop-down menus to complete the statements ab

Snezhnost [94]

Answer:

Because the object on scale 1 weighs more than the object on scale 2, each pound of error results in a lesser percent error. Scale 1 was 10 pounds off and scale 2 was 3 pounds off, so scale 1 was 10% off and scale 2 was 12% off.

The object on scale 1 weighs 100 pounds and the object on scale 2 weighs 25 pounds so the object on scale 1 weighs more than scale 2.

Scale 1 error margin: Scale 2 error margin:

= Actual weight - measured weight = 25 - 22

= 100 - 90 = 3 pounds

= 10 pounds

Scale 1 error percentage: Scale 2 error percentage:

= Error margin/ Actual weight = 3/25

= 10/100 = 12%

= 10%

Scale 1 object has less percent error.

ILL GIVE YOU BRAINLIST ! Marlene is given 7 feet of fabric to design a dress. She uses 6 1/9 feet of fabric. How much fabric is

ivolga24 [154]

Answer:

This question is a lot easier than it seems. What you have to do here is subtract 6 1/9 from 7.

This will give you 0.8 of the fabric left, or 8/9.

−5 + (−5r) + 10 Not that hard but I keep getting stuck

djverab [1.8K]

5-5r

-5 and 10 have like terms, so you can add them
they make positive 5
(-5r) is just -5r, and you can't add it to a number without a variable
so the answer is 5-5r

PLEASE HELP ME ACE THIS angle a = ___ degrees

Ludmilka [50]

Angle B = ADC arc / 2

32 = ADC arc / 2

ADC arc = 2 × 32

ADC arc = 64

_________________________________

ADC arc + ABC arc = 360

64 + ABC arc = 360

ABC arc = 360 - 60 - 4

ABC arc = 300 - 4

ABC arc = 296

_________________________________

Angle D = ABC arc / 2

x = 296 / 2

x = 148

_________________________________

Angle A = x - 40

Angle A = 148 - 40

Angle A = 108 degrees
