S) This question is asking me to find the volume of the backpack.
O) Identify the facts: compartment one is 14x3x10, compartment two is 12x2x10, Julissa got a new backpack
Eliminate the unnecessary facts: Julissa got a new backpack
List the necessary facts: compartment one is 14x3x10, compartment two is 12x2x10
L) I chose Multiplication, I will multiply the measurements of compartment one, then multiply the measurements of compartment two and add them together to find the volume of the backpack.
V) I think the backpack will be at least 300 inches cubed.
(SOLVING PART)
Compartment one: 12 times 2 times 10 = 240
Compartment two: 14 times 3 times 10 = 420
420 + 240 = 660
E) Julissa’s backpack is 660 inches cubed.
I hope this helps
Answer:Answer:
13.0feet
Step-by-step explanation:
Given ΔDEF with ∠F=90°, the measure of ∠D=19°, and DE = 40 feet, since one of the angles of the triangle is 90°, the triangle is a right angled triangle as shown in the attachment.
Using SOH, CAH, TOA to get the unknown EF.
Since <D is opposite to side EF, EF will be the opposite while side DE will be the hypotenuse
Based on SOH:
Sin<D = Opposite/Hypotenuse
Sin<D = EF/DE
Sin19° = EF/40
EF = 40sin19°
EF = 13.0 feet to the nearest tenth of a foot
4370
123

13110
+87400

537510
Then you add the number of space the coma takes in the two numbers, so 2+1=3 and u put it in the third place so the answer is : 53,751
