MR. WINTER WAS STANDING ON THE MIDDLE RUNG OF HIS LADDER. HE THEN STEPPED UP 4 RUNGS, THEN DOWN 6 RUNGS. LATER HE CLIMBED BACK UP 7 RUNGS. FINALLY, HE CLIMBED UP 5 MORE RUNGS AND REACHED THE TOP OF THE LADDER. HOW MANY RUNGS WERE THERE ON HIS LADDER?

Answer:

The reason why it helps to have a plan of proof before writing the proof is that the proof plan is the collection of recollected knowledge about the question that will ensure that the required proof is achieved

The proof plan is equivalent to a  virtual construction, consisting of the required parts and how the parts fit together, that obeys or satisfies the actual conditions when the written, step by step on paper

Without a proof plan, the required parts of the proof and therefore how the parts will fit to provide the proof will be absent as well as the non required parts written down to provide a proof without a plan can be confounding

Answer:

Step-by-step explanation:

Step one:

given data

we are told that the sales person's earnings is 4% of the sales made.

given that the sales made is $37,000 worth of furnaces.

Step two:

we want to find 4% of $37,000

=4/100*37000

=0.04*37000

=1480

hence for $37,000 the earning will be $1480.

Now suppose sales is doubled that is 37000*2= 74000

we want to find 4% of $74,000

=4/100*74000

=0.04*74000

=2960.

the earnings is $2960.

So if sales doubles the earnings will double

Answer:

The answer is letter D.

If we solve the given function when the functions are f(x)=[tex]\sqrt{6x}[/tex] and g(x)=[tex]\sqrt{24x}[/tex] then we will be able to find it equal to 12x.

A function is a relation in which each element of x is having a value in the y element. It is written in the form of f(x).

f(x)=[tex]\sqrt{6x}[/tex] and g(x)=[tex]\sqrt{24x}[/tex]

(f.g)x=f(x)*g(x)

=[tex]\sqrt{6x} *\sqrt{24x}[/tex]

=[tex]\sqrt{6x}*2\sqrt{6x}[/tex]

=2*6x

=12x

Hence the value of (f.g)x is 12x.

Measure of EF: 1.98

Measure of AB: 6.16

Measure of HI: 12.2

Step-by-step explanation:

Trick I learned that's very helpful when solving these problems: SOH (Sine, Opposite, Hypotenuse)- CAH (Cosine, Adjacent, Hypotenuse)- TOA (Tangent, Opposite, Adjacent)

MEASURE OF EF

you're starting with angle D which is 26 degrees. You have the measure of the Hypotenuse (DF) and you're trying to find the measure of EF (the segment opposite the angle) so you would use Sine

to do the equation, i'm going to use x in place of EF. 0.44 = sin(26)

Formula: sin(angle) = (opposite)/(hypotenuse)

Equation:

0.44 = x/4.5       <----------- multiply by 4.5 to get x by itself

4.5*0.44 = x       <---------- 4.5 times 0.44

1.98= x       <----------------answer

MEASURE OF AB

trying to find hypotenuse and you already have the adjacent angle so you would use cosine. Using y in place of AB. 0.616 = sin(52)

cos(angle) = (adjacent)/(hypotenuse)

cos(52) = 10/y      <------ divide by y

y*0.616 = 10       <------------ divide by 0.616

y = 10/0.616    <----------- next you'll divide 10 by 0.616

y = 6.16    <-----------answer

MEASURE OF HI

trying to find adjacent, already have opposite so you would use tangent. tan(42) = 0.90. using z in place of HI

tan(angle) = (opposite)/(adjacent)

tan(42) = 11/z   <------------ multiply z on both sides

z*0.90 = 11  <--------- divide by 0.90 to get z by itself

z = 11/0.90    <-------- divide 11 by 0.90

z = 12.2

Answer:

No, there is no enough flour for each of his friends to get a cupcake

Step-by-step explanation:

Let us use the ratio method to solve the question

∵ This recipe makes 2[tex]\frac{1}{2}[/tex] dozen cupcakes

∵ Each dozen contain 12 cupcakes

∴ The number of cupcakes can the recipe make = 2[tex]\frac{1}{2}[/tex]  × 12

∴ The number of cupcakes can the recipe make = 30 cupcakes

∵ The recipe calls for 3[tex]\frac{1}{3}[/tex] cups of flour

→ That means 3[tex]\frac{1}{3}[/tex] cups of flour can make 30 cupcakes

∴ 3[tex]\frac{1}{3}[/tex] cups of flour makes 30 cupcakes

∵ Anthony’s mother has only 1 cup of flour

→ By using the ratio method

→  flour  :  cupcake

→  3[tex]\frac{1}{3}[/tex]      :  30

→   1       :   x

→ By using cross multiplication

∵ 3[tex]\frac{1}{3}[/tex] × x = 1 × 30

∴ 3[tex]\frac{1}{3}[/tex] x = 30

→ Divide both sides by 3[tex]\frac{1}{3}[/tex]

∴ x = 9

∵ x represents the number of cupcakes  

∴ Anthony’s mother can make 9 cupcakes with 1 cup of flour

∵ Anthony has 12 friends at his daycare

∵ The number of the cupcakes = 9

∴ The number of cupcakes is not enough for each of his friends to

   get a cupcake

Given:

Initial speed of typing = 35 words per minute

At the end of the course her typing speed = 77 words per minute

To find:

The percent of increase in her typing rate.

Solution:

We know that,

[tex]\text{Percent of increase in her typing rate}=\dfrac{\text{New speed - initial speed}}{\text{Initial speed}}\times 100[/tex]

[tex]\text{Percent of increase in her typing rate}=\dfrac{77-35}{35}\times 100[/tex]

[tex]\text{Percent of increase in her typing rate}=\dfrac{42}{35}\times 100[/tex]

[tex]\text{Percent of increase in her typing rate}=120\%[/tex]

Therefore, her typing rate is increased by 120%.
