Bethany is baking cookies for her school's bake sale. She plans to bake more than 185 cookies, in batchs or 12 cookies. so far,

Bethany has baked a total of 48 cookies. What inequality describes this situation, if b represents the number of batches of cookies Bethany has left to bake?

Answer:

48+12b≥185

Step-by-step explanation:

Inequality: 48+12b≥185

Why? she has already backed 48 cookies so you just need to find how many more she needs to bake. (she doesn't need 185 cookies anymore since she's already baked 48)

You don' t need to solve the question,  

But here is how you do...

12b≥137

b≥11.42 (roughly)

I don’t understand how to do this problem. How would I solve it?
artcher [175]

Answer:

About 2.569 seconds

Step-by-step explanation:

To solve this problem, you can separate it into two half parabolas. The beginning part is initial upward rising. To calculate the amount of time that this part of the dive takes, you can use the formula v_f=v_o+at, where v_f is the final velocity, v_o is the initial velocity, a is the acceleration due to gravity, and t is the amount of time it takes. You know that the final velocity is 0, since the diver is reaching the terminal of their dive. Therefore, you can set up the following equation (assuming that the acceleration due to gravity is 32ft/s^2):

0=5+(-32)t

t=5/32 seconds

To find the height that this indicates the diver has risen, you can plug this time into the following formula: d=v_o t+\frac{1}{2}at^2

d=5(5/32)+\frac{1}{2}\cdot 32\cdot (5/32)^2\approx 1.172 feet

For the second part, you can use the equation d=v_o t+\frac{1}{2}at^2 again. Since the initial velocity for this part is 0, you can set up the following equation:

92+1.172=\frac{1}{2}\cdot 32 \cdot t^2

t \approx 2.413

Adding this to the time that the first part of the dive takes, you get a total of about 2.569 seconds. Hope this helps!

One angle of a right triangle measures 70 degrees. What is the other acute angle?
Sunny_sXe [5.5K]

Answer:

20 degrees

Step-by-step explanation:

A triangle's angles should 180 degrees added together, so 90 + 70 = 160, leaving 20 for the last angle.

2 gallons : 31 miles

15.5, because 31 divided by 2 is 15.5.  And all the other number divided by the number below them also turns out to be 15.5. 

Hope this helps. :)

PLEASE HELP ASAP!!!!
Naily [24]

Answer:

2

Step-by-step explanation:

Using the rule of logarithms

log_{b} x = n ⇒ x = b^{n}

let

log_{2} 8 = n ⇒ 8 = 2^{n} , that is

2³ = 2^{n} ( equate exponents )

n = 3

and let

log_{3} ( \frac{1}{3} ) = n ⇒ \frac{1}{3} = 3^{n} , that is

3^{-1} = 3^{n} ( equate exponents )

n = - 1

then

log_{2} 8 + log_{3} (\frac{1}{3} )

= 3 + (- 1)

= 3 - 1

= 2
