Make a comparison
\frac{height}{shadow}= \frac{height}{shadow}
\frac{heightof tree}{shadow of three}= \frac{heightofJohn}{shadow of John}

Plug the numbers into the equation above
h stands for the height of tree
\frac{heightof tree}{shadow of three}= \frac{heightofJohn}{shadow of John}
\frac{h}{18}= \frac{6}{3.5}

Do cross multiplication
3.5h = 6 × 18
3.5h = 108
h = 108/3.5
h = 30.8571..

to the nearest hundredth
h = 30.86 feet
to the nearest tenth
h = 30.9 feet

Answer:

28 numbers

Step-by-step explanation:

There is a distance of 81 between -0.5 and 80.5. Divide this number by 3, since you are only counting every third number and you will get 27, but you need to count the first number, which has been excluded. Add one more to get the answer, 28.

Answer:  There are 108 hammers, and there are 36 screwdrivers. 36×3=108·

Step-by-step explanation: We know that there are more hammers than screwdrivers, so there are 36 screwdrivers but there are 3 times as many hammers so we multiply 36 by 3 to get 108.

A worker at a mill is loading 10-lb bags of flour into boxes to deliver to a local warehouse. Each box holds 4 bags of flour. If
Hunter-Best [27]

Answer: 100 boxes

Step-by-step explanation:

Hi, since 1 ton = 2,000 lbs

We have to divide 10lbs by 2000 to convert the lbs in tons.

1t/2000lb = xt / 10lb

10 /2000=0.005

0.005 ton = 10 lbs (1 bag)

Each box has 4 bags

0.005 ton x 4 = 0.02 ton

So each box weights 0.02 ton

Since we need 2 tons.

Using proportions:

0.02t/1 box= 2 t / x boxes

x = 2 / (0.02/1)

x = 100 boxes  

Feel free to ask for more if needed or if you did not understand something.

Can anyone please help with these 2 questions. If you can, please show step-by-step.

Answer:

1. x = 21

2. m∡ABC =  51°

Step-by-step explanation:

First problem, solve for x

the sum of inside angles of a triangle is 180

also the supplementary angle for L = 180 - 100 is 80°

now you can add all angles

80 + 2x - 11 + 2x + 27 = 180

4x + 96 = 180

4x = 84

x = 21

Second problem, solve for m∡ABC

the sum of inside angles of a triangle is 180

also the supplementary angle for C = 180 - 148 is 32°

now you can add all angles

31 + 2x - 15 + x - 5 = 180

3x + 12 = 180

3x = 168

x= 56,

now solve for  m∡ABC = (x - 5)° = (56 - 5)° = 51°
