Giovanni is visiting his grandmother who lives in an apartment building on the 25th floor. Giovanni enters the elevator in the lobby, which is the first floor of the building. The elevator stops on the 16th floor. What percentage of 25 floors does Giovanni have left to reach his grandmothers floor?

Answer:

your answer will be m<b=37

Step-by-step explanation:

hope it helps

Answer:

37°

She likely thought that angle b and 53° added up to 180 instead of 90

Step-by-step explanation:

b and 53° make a right angle

b + 53° = 90°

90° - 53° = 37°

She likely thought that angle b and 53° added up to 180 when it actually adds up to 90

Answer:

40.8 minutes

Step-by-step explanation:

Element X decays radioactively with a half life of 8 minutes. If there are 480 grams of Element X, how long, to the nearest tenth of a minute, would it take the element to decay to 14 grams?

The formula to find how long it would take which is the time elapsed is given as:

t = t½ × In(Nt/No)/-In2

t = ?

t½ = 8 minutes

Nt = Amount after the time of decay = 14 grams

No = Original Amount of substances = 480 grams

t = 8 × In(14/480)/-In2

t = 40.796285388407 minutes

Approximately to the nearest tenth = 40.8 minutes

Therefore, it would take the element X, 40.8 minutes to decay to 14 grams

Answer:

Length = 16 in

Width = 12 in

Step-by-step explanation:

Given:

Area of a rectangle = 192 in²

Ratio(length to width) = 4:3

Find:

Length and the width

Computation:

Ratio(length to width) = 4:3

So,

Length = 4a

Width = 3a

Area of a rectangle = Length x Width

192 = 4a x 3a

192 = 12a²

a² = 16

a = 4

Length = 4a = 4 x 4 = 16 in

Width = 3a = 3 x 4 = 12 in

Explanations:

Answer: 8 units

Step-by-step explanation:

This can be solved using the Pythagorean Theorem:

c² = a² + b²

c is the hypotenuse

a and b are the sides

Solving for the length:

10² = 6² + b²

100 = 36 + b²

b² = 100 - 36

b² = 64

b = √64

b = 8 units

The missing side is 8 units.

52.38%

Answer: 100

Step-by-step explanation:

1 cubic inch would just be 100 because each cube is 1 cubic inch. So 100(number of cubes)/1(cubic inch)=100 I hope I'm right :)

Answer:

Step-by-step explanation:

Length of a pair of skis = 6 feet 11 inches

Maximum length of a the skis that can be fitted in a wardrobe is along the diagonal of the wardrobe.

From the picture attached,

BC² = 3² + 2² [By Pythagoras theorem]

BC = √(13)

By applying Pythagoras theorem in ΔABC,

AB² = AC² + BC²

AB² = 6² + (√13)²

       = 36 + 13

AB = √49

Ab = 7 feet

Since, "diagonal length of the wardrobe is more than the length of skis,

skis can be fitted"

Answer:

Option B.

Step-by-step explanation:

When we have an angle A, in degrees, the coterminal angles are all the angles that can be written as:

B = A + n*360°

Where n is a positive or a negative integer (if n = 0, then B = A, which means that A is coterminal with itself, which is trivial).

Now we want to find two coterminal angles to 117°, such that one is positive and the other negative.

Then we can do:

for the positive one, use n = 1.

B = 117° + 1*360° = 477°

For the negative one, use n = -1

B = 117° - 1*360° = -243°

Then the two angles are 477° and -243°

The correct option is B.

Answer:

The first one does not work, the second one does.

Step-by-step explanation:

Use the triangle inequality formula:

a = 15

b = 37

c = 53

15 + 37 > 53 No

It does not work.

a = 9

b = 16

c = 8

9 + 16 > 8 Yes

9 + 8 > 16 Yes

16 + 8 > 9 Yes

The first one does not work, the second one does.

x=3

Step-by-step explanation:

Answer:

The simplified ratio of ALL the pens to pencils is

= 3:2

Step-by-step explanation:

A canister holds 3 blue pens, 4 black pens, 2 red pens, and 6 pencils.

Step 1

Sum of all the pens is:

Blue pens + Black pens + Red pens

= 3 + 4 + 2

= 9 pens

Number of pencils = 6 pencils

Step 2

The simplified ratio of ALL the pens to pencils is

Pens : Pencils

= 9 : 6

= 3:2

Answer:

y = -240

Step-by-step explanation:

If y varies jointly as x and z, then y/(xz) = k where k is the constant of proportion

60/10(-3) = 60/-30 = -2 = k

Now,  y/(xz) = -2

          y/8(15) = -2

          y/120 = -2

                y = -240

Answer: 4 hours, $160

Step-by-step explanation:

100+15x= 40x

100= 25x

4=x

4 Hours

4*40 = 160

or 100 + 15*4= 160

Question:

In triangle FGH, the measure of angle H = 90°, HG = 48, FH = 55, and GF = 73. What ratio represents the tangent of angle G?

___________________________________________________

Solution:

The triangle FGH should look like that in the attachment.

Tangent of angle G = opposite side/adjacent side

= FH/HG

= 55/48

Answer:

3t+ 7 < 28

Step-by-step explanation:

The inequality function as follows;

Given that the cost is $7

There are three tubs of popcorn i.e. t

And, if the girl spend lower than $28 so the inequality function is

3t + 7<28

Hence, the above represent the answer

Answer:

18.7 wreaths

Step-by-step explanation:

Beverly makes wreaths to sell for the fall season. She picked 430 pine cones from the wooded area near her house. If she uses 23 pine cones per wreath, how many wreaths can she make?

From the above question:

23 pine cones = 1 wreath

430 pine cones = x wreaths

Cross Multiply

23 pine cones × x wreaths = 430 pine cones × 1 wreath

x wreaths = 430 pine cones × 1 wreath/23 pine cones

x wreaths = 18.695652174 wreaths

Approximately = 18.7 wreaths
