What mixed number is equal to 13/4

2 answers:

8 0

It would be 3 1/4 because you basically see how many times 4 would go into 13 and in this case it is 3 (3 x 4 = 12) and after you get 12 you have one left (13-12=1) so you would have one fourth left therefore the answer would be 3 1/4. hope this helped!

1. A MAP SCALE READS 1CM:5KM. IF A DISTANCE ON THE MAP MEASURES 7CM, THE ACTUAL DISTANCE WILL BE?. 2. A SCHOOL DINING HALL IS 35

Agata [3.3K]

Answer:

1. 35 km

2. 1 cm to 5m

3. 6 cm

4. $42^\circ$

5. 16.73 m

Step-by-step explanation:

Solution 1.

Reading of map scale = 1cm:5km

i.e. 1 cm is equivalent to 5 km

Measurement of map = 7 cm

Actual distance = Measurement of map $\times 5$

Actual distance = 7 $\times 5$ = 35 km

-------------------

Solution 2.

Length of dining hall = 35 m

Measurement of map = 7 cm

Scale = Measurement of map : Length of dining hall (i.e. ratio)

Scale = 7 cm :35 m = 1 cm : 5 m

-------------------

Solution 3.

Length of building = 30 m

Scale = 1 cm to 5m

5 m is equivalent to 1 cm on scale

1 m is equivalent to $\frac{1}{5}$ cm on scale

30m is equivalent to $\frac{1}{5} \times 30$ = 6 cm on scale

-------------------

Solution 4.

Angle of elevation of A from B = $42^\circ$

Angle of depression of B from A = ?

Please refer to the image attached, we can clearly observe that both the angles (i.e. angle of elevation from A to B and angle of depression from B to A )will be equal.

Angle of depression of B from A = $42^\circ$

-------------------

Solution 5.

Given that:

String length, or hypotenuse of triangle BC= 25 m

Angle of string with horizontal, $\angle B = 42^\circ$

Please refer to the attached image for the clear understanding of the situation.

To find:

Height, AC = ?

We can use trigonometric identity:

$sin\theta = \dfrac{Perpendicular}{Hypotenuse}$

$sinB = \dfrac{AC}{BC}\\\Rightarrow sin42^\circ = \dfrac{AC}{25}\\\Rightarrow AC = 25 \times 0.67\\\Rightarrow AC = 16.73 m$

============

So, the answers are:

1. 35 km

2. 1 cm to 5m

3. 6 cm

4. $42^\circ$

5. 16.73 m

HELP there due to tomorrow :/

Cerrena [4.2K]

Answer:

First Answer:

$15,060.

Second Answer:

9.96 miles.

Third Answer:

$3.27.

Step-by-step explanation:

First Question:

Cost of the rented car = 50 + 0.20 = $50.20

How much did Matt's family spend for the car:

1 mile = $50.20

300 miles = ?

300 × 50.20

= $15,060.

Second Question:

If Hayden spent $500 for her rented car, how many miles did she drive:

$50.20 = 1 mile

$500 = ?

500 ÷ 50.20 = 9.96 miles.

Third Question:

What is the cost per gallon of gas:

24 gallons = $78.48

1 gallon = ?

78.48 ÷ 24 = $3.27.
