Ted is making a bread recipe that uses three 1/4 cups of flour and a muffin recipe that uses 2 3/4 cups of flour eggs. How much

wlad13 [49]

Amount of flour used in bread recipe = $3 \frac{1}{4}$ cups

Amount of flour used in muffin recipe = $2 \frac{3}{4}$ cups

We have to determine how much more flour is in the recipe.

Since, more amount of flour is used in bread recipe than in muffin recipe.

Total amount of more flour = $3 \frac{1}{4} - 2 \frac{3}{4}$

= $\frac{13}{4} - \frac{11}{4}$

= $\frac{2}{4}$

= $\frac{1}{2}$

Therefore, $\frac{1}{2}$ more cup of flour is used in bread recipe than in muffin recipe.

Now, we will determine the total amount of flour used in both recipe.

Total amount of flour used in bread and muffin recipe

= $3 \frac{1}{4} + 2 \frac{3}{4}$

= $\frac{13}{4} + \frac{11}{4}$

= $\frac{24}{4}$

= 6 cups

Therefore, total 6 cups of flour are used in both the recipes.

A right triangle has one angle that measure 23o. The adjacent leg measures 27.6 cm and the hypotenuse measures 30 cm.

MrMuchimi

Answer:

161.8cm²

Step-by-step explanation:

solve for height which is the opposite

opp=x

sin(theata)= opp./hyp.

sin23=x/30

x=30×sin23

x=11.72cm

height=opposite

height=11.72cm

base=adjacent

base=27.6cm

½of 27.6cm=13.8

13.8cm×11.72cm=161.74 (2d.p)

161.74 rounded to the nearest tenths= 161.7

I'm not sure if it's the answer but it's the closest thing to the options

I need to find sec(theta)= 2(sqrt3)/3

Sloan [31]

Answer: 30° and 330°

Step-by-step explanation:

sec θ = $\frac{2\sqrt{3}}{3}$

sec θ = $\frac{1}{cos(\theta)}$

$\frac{1}{cos(\theta)}$ = $\frac{2\sqrt{3}}{3}$

cos θ = $\frac{3}{2\sqrt{3}}$

cos θ = $\frac{3}{2\sqrt{3}}(\frac{\sqrt{3}}{\sqrt{3}})$

cos θ = $\frac{3\sqrt{3}}{3*2}$

cos θ = $\frac{\sqrt{3}}{2}$

Look at the Unit Circle to see that cos = $\frac{\sqrt{3}}{2}$ at 30° and 330° ( which is equivalent to π/6 and 11π/6)
