Lakesha gave three tenths of her cookies to Bailey and five tenths of her cookies to Helen. What fraction of her cookies did Lak

Mashutka [201]

Answer:

a . eight tenths of her cookies

Explanation:

Let the total number of Lakesha's cookies be represented by x.

So that;

She gave three tenths to Bailey = $\frac{3}{10}$ of x

= $\frac{3x}{10}$

She gave five tenths to Helen = $\frac{5}{10}$ of x

= $\frac{5x}{10}$

Fraction of Lakesha's cookies given away = $\frac{3x}{10}$ + $\frac{5x}{10}$

= $\frac{3x+ 5x}{10}$

= $\frac{8x}{10}$

Thus, the fraction of cookies given away by Lakesha is $\frac{8}{10}$ .

How many joules of heat are required to raise the temperature of 320.0 grams of water from 24.2°C to 50.8°C? Heat capacity of wa

balu736 [363]

Answer:

35750.4 Joules

Explanation:

Using the formula as follows;

Q = m × c × ∆T

Where;

Q = amount of heat (joules)

m = mass of substance (g)

c = specific heat capacity (J/g°C)

∆T = change in temperature (°C)

According to the provided information,

mass (m) = 320.0 grams

c = 4.2 J/g°C

∆T = (50.8°C - 24.2°C) = 26.6°C

Q = ?

Using; Q = m × c × ∆T

Q = 320 × 4.2 × 26.6

Q = 35750.4 J
