Hi ;-)

$\text{s}=-8 \ \text{and} \ \text{t}=\frac{3}{4}\\\\\text{s}^2\text{t}-10=(-8)^2\cdot\frac{3}{4}-10=\\\\=64\cdot\frac{3}{4}-10=16\cdot3-10=48-10=\boxed{38}$

The formula F = 1.8C + 32 allows you to find the Fahrenheit (F) temperature for a given Celsius (C) temperature. Solve the equat

Slav-nsk [51]

Answer:

The formula to calculate the Celsius temperature for a given Fahrenheit temperature is:

$C=\frac{F-32}{1.8}$

Step-by-step explanation:

Given formula:

$F=1.8C+32$

where $F$ represents temperature in Fahrenheit and $C$ represents temperature in Celsius.

To solve the equation for $C$ .

Solution:

We have,

$F=1.8C+32$

Subtracting both sides by 32.

$F-32=1.8C+32-32$

$F-32=1.8C$

Dividing both side by 1.8

$\frac{F-32}{1.8}=\frac{1.8C}{1.8}$

$\frac{F-32}{1.8}=C$

∴ $C=\frac{F-32}{1.8}$

Using the above formula, we can calculate the Celsius temperature for a given Fahrenheit temperature.

Activity 1.1 Simplify Me Simplify by removing perfect nth powers: 1. √20 2. √300 3. √128 3 4. √ 5 3 5. √50 3

LekaFEV [45]

Answer:

$(a)\ \sqrt{20}=2\sqrt{5}$

$(b)\ \sqrt{300} = 10 \sqrt{3}$

$(c)\ \sqrt{128} = 8 \sqrt{2}$

Step-by-step explanation:

Required

Simplify

$(a)\ \sqrt{20}$

Express 20 as 4 * 5

$\sqrt{20}=\sqrt{4 * 5}$

Split

$\sqrt{20}=\sqrt{4} * \sqrt{5}$

This gives:

$\sqrt{20}=2 * \sqrt{5}$

$\sqrt{20}=2\sqrt{5}$

$(b)\ \sqrt{300$

Express as 100 * 3

$\sqrt{300} = \sqrt{100} * \sqrt{3}$

This gives:

$\sqrt{300} = 10 * \sqrt{3}$

$\sqrt{300} = 10 \sqrt{3}$

$(c)\ \sqrt{128}$

Express as 64 * 2

$\sqrt{128} = \sqrt{64*2}$

Split

$\sqrt{128} = \sqrt{64} * \sqrt{2}$

$\sqrt{128} = 8 * \sqrt{2}$

$\sqrt{128} = 8 \sqrt{2}$

Solve the formula A=12bh for h when A=90 and b=15. Write the answer in decimal form.

ohaa [14]

Answer:

Given,

A=90

b=15

A=12bh

Now,

Step-by-step explanation:

Put the given value in the formula

A=12bh

90=12*15*h

90=180h

90/180=h

Hence, h=0.5
