If 20 large cakes are needed, you'll need 4 helpers. To find this, you first need to find how many cakes 1 helper can make. Every hour, one helper can make 2 large cakes. If they have the kitchen for 3 hours, 6 large cakes can be made by one helper. This also means that 2 helpers make 12 cakes, 3 helpers can make 18 cakes, and 4 helpers can make 24 cakes. Since you can't have a fraction of a helper, 4 is your answer. For the 700 small cakes, you do the same thing. Every hour, 1 helper makes 35 small cakes. In 3 hours, 1 helper can make 105 small cakes. 2 can make 210, 3 can make 315, 4 can make 420, 5 can make 525, 6 can make 630, and 7 can make 735. The 700 small cakes takes 7 helpers and the 20 large cakes takes 4 helpers. Your total amount of helpers is 11.

11 1/2 and 13 3/4 is?
Tpy6a [65]
This would depend on what you are asking for.

If you are adding the two numbers(which the word and is implying) you’re answer is 25 1/4.

You get this by finding a common denominator. In this case, that can be 4.

Turn 1/2 in to 2/4.

Next, you add 11 and 13 to get 24.

Then, you’ll add 2/4 and 3/4. You will get 1 1/4

Add 24 and 1 1/4. You have your answer of 25 1/4

If you place a 41-foot ladder against the top of a 40-foot building, how many feet will the bottom of the ladder be from the bot
garri49 [273]

Answer:

9

Step-by-step explanation:

The ladder is the hypotenuse, the wall is one of the legs. In order to find the other leg you have to do c^2-a^2=b^2. 41^2-40^2 is 81 and the square root of that is 9

J and K are vertical angles. J and L are supplementary angles. mK=71° What is mL in degrees?​
Advocard [28]

\large{\green{\underline{\underline{\bf{\orange{ANSWER:-}}}}}}

The question and data provided in the information is that (<J ≈ <K) are congruent to each other. Then (<J + <L = 180°) here supplementary means that there sum tends to 180°. And we have also provided the value of <K = 71°.

Now as per question we can write that,

\longrightarrow\bf{ \angle j  + \angle l = 180}

\longrightarrow\bf{ \angle k  + \angle l = 180 \: .... \: ( \angle j = \angle k)}

Now substituting values,

\longrightarrow\bf{71 +  \angle l = 180}

\longrightarrow\bf{  \angle l = 180 - 71}

\longrightarrow\bf{  \angle l = 109}

  • The value of <L = 109°
