1 answer:
Alja [10]3 years ago
4 0

Answer:

False, there are infinite solutions

Step-by-step explanation:

Try solving this

3y - 6x = 24

8 + 2x = y

3(8 + 2x) - 6x = 24

24 + 6x - 6x = 24

24 = 24  true

(1+(0.065÷365))^365t=4
marta [7]
This is the future value quadrupled in t years at an annual interest rate of 6.5% compounded daily.  We need to find t.

1*(1+0.065/365)^(365t)t=4
take log on both sides,
365t(log(1+0.065/365)=log(4)
=>
365t=log(4)/log(1+0.065/365)
t=(log(4)/log(1+0.065/365))/365
=(1.38629/.000178066)/365
=21.33 years

Check with the rule of 69, applicable to continuous compounding (an approximation to current problem) to double money, it take 69/interest rate in % years.
=69/6.5
=10.62 years
To double twice (quadruple), it takes twice 10.62
=21.24 years, not that far from 21.33 that we got earlier.

Use the following recipe to answer questions 1 through 4:
grandymaker [24]

Answer:

1. pounds (lb)

2. pints (pt)

3. teaspoon (tsp)

4. cups (c)

Step-by-step explanation:

<h3><u>US Standard Units</u></h3>

<u>Liquid</u>

  • Fluid Ounces (fl oz)
  • Cups (c)
  • Pints (pt)
  • Quarts (qt)
  • Gallons (gal)

128 fl oz = 16 cups = 8 pints = 4 quarts = 1 gallon

<u>Mass</u>

  • Ounces (oz)
  • Pounds (lb)
  • Tons (short ton)

32000 ounces = 2000 pounds = 1 ton

<h3><u>Solutions</u></h3>

1.  The best US standard unit in which to measure pumpkin with a mass of 1.2 kg would be pounds (lb).

⇒ 1 kg ≈ 2.205 lb

⇒ 1.2 kg ≈ 1.2 × 2.205 = 2.65 lb

2. The best US standard unit in which to measure stock with a volume of 1.5 L would be pints (pt).

⇒ 1 L ≈ 2.133 pt

⇒ 1.5 L ≈ 1.5 × 2.113 = 3.17 pt

3. The best US standard unit in which to measure sugar of 5 mL would be teaspoon (tsp).

⇒ 5 mL = 5 g ≈ 1 teaspoon

4.  The best US standard unit in which to measure yogurt with a volume of 0.25 L would be cups (c).

⇒ 1 L ≈ 4.167 c

⇒ 0.25 L ≈ 0.25 × 4.167 =  1.04 c

15. In AABC if mZA is thirteen less than mzC and mZB is eleven less than four times m
vlabodo [156]

Answer:

m\angle A=21°

m\angle B=125°

m\angle C=34°

Step-by-step explanation:

Let the measure of angle C be x°.

Given:

In triangle ΔABC,

m\angle A is thirteen less than m\angle C and m\angle B is eleven less than four times m\angle C. This gives,

m\angle A = x-13

m\angle B=4x-11

Also, m\angle C=x

Now, for a triangle, the sum of all its interior angles is equal to 180°.

Therefore, m\angle A + m\angle B + m\angle C=180

Plug in all the values and solve for x. This gives,

x-13+4x-11+x=180\\6x-24=180\\6x=180+24\\6x=204\\x=\frac{204}{6}=34

Therefore, measure of angle C is 34°.

Measure of angle A is, m\angle A=x-13=34-13=21°.

Measure of angle B is, m\angle B=4x-11=4(34)-11=136-11=125°.
