Answer:

Noah types faster because he can type more words per minute.

Step-by-step explanation:

For Andre you would divide 208 words by 4 minutes getting 52 words per minute. Then, for Noah divide 342 words by 6 minutes getting 57 words per minute.

Answer:

286.

Step-by-step explanation:

9.85^3 /3.875 + 6.3^2

= 10^3/ 4 + 6^2

= 1000/4 + 36

=250 + 36

=286.

Answer:

Rock costs $3.20 per pound.

Step-by-step explanation:

Because sand costs three times as much as rocks per pound, you can determine the cost of rocks per pound by dividing the cost of sand per pound by three:

[tex]\frac{9.60}{3}[/tex] [tex]= 3.20[/tex]

Answer:

She baked 90 cookies.

Step-by-step explanation:

From the information given you know that 36 cookies represent 40% of the cookies that were baked. With this information, you can use a rule of three to find the total mount of cookies that she baked:

36 cookies →  40%

        x         ← 100%

x=(36*100)/40=90

According to this, the answer is that she baked 90 cookies.

Answer:

525 children attended the concert.

Step-by-step explanation:

Given that:

Total number of people who attended concert = 2500

Adult females = 47%

Adult males = 32%

Percent of children = (100-47-32)% = 21%

Number of children = 21% of people who attended

Number of children = [tex]\frac{21}{100}*2500[/tex]

Number of children = 0.21*2500 = 525

Hence,

525 children attended the concert.

Answer:

b.430

Step-by-step explanation:

Answer:

Explanation: the ratio 2:4 can be reduced to 1:2, where the number of girls corresponds to the 1 and the number of boys corresponds to the 2. If there are 14 girls, then there must be 28 boys (14 x 2 = 28). Now to get the total number we need to add the total number of boys and girls together. So 14 + 28 = 42

Answer:

x ≥ $750

Step-by-step explanation:

Answer:

1. 1.925 Liters

2.  0.075 Liters  less than the 2 Liter of special drink

Step-by-step explanation:

Step 1

Quantity of lemon juice = 0.375 Liters

Quantity of cranberry juice = 0.35 liters

Quantityof water = 1.2liters

Total Quantity of  Special drink = 0.375 L+ 0.35L + 1.2 L= 1.925 Liters

Step 2

But since she wanted to make 2 Liters of the special drink she will have

2 Lter - 1.925L= 0.075Liters  less than the initial 2 Liter of special drink planned.

Answer:

a. 1.925 litres

b. 0.075 litres less

Step-by-step explanation:

a. How much of the special drink can she make?

To find out the quantity of juice produced, add the component juice quantities and the water:

= 0.375 + 0.35 + 1.2

= 1.925 litres

b. How much more or less than 2 litres will she have?

= 2 - 1.925

= 0.075 litres less

Answer:

which team has the taller player (picture involve

B the skyview ravens

Answer:

the davis tigers has taller player

because their player is 0.625 inches taller more than the Skyview Ravens player

Solution :

From the triangle,

[tex]$x^2 = s^2 + 90^2$[/tex]

[tex]$x = \sqrt{s^2 + 90^2}$[/tex]

Now differentiating w.r.t "t", we get

[tex]$\frac{dx}{dt}=\frac{d}{dt}\left(s^2 +90^2 \right)^{1/2}$[/tex]

    [tex]$=\frac{1}{2}\left(s^2 + 90^2 \right)^{\frac{1}{2}-1} \cdot 2s \cdot \frac{ds}{dt}$[/tex]     [chain rule]

    [tex]$=\frac{1}{2}\left(s^2 + 90^2 \right)^{-\frac{1}{2}} \cdot 2s \cdot \frac{ds}{dt}$[/tex]

    [tex]$=\frac{s}{\left(s^2 + 90^2\right)^{\frac{1}{2}}} . \frac{ds}{dt}$[/tex]  

But given that [tex]$\frac{ds}{dt}$[/tex] = 100 ft/s

When all the ball crosses the third base, this means that s = 90. So substituting the value of s and [tex]$\frac{ds}{dt}$[/tex]  in [tex]$\frac{dx}{dt}$[/tex] , we get

[tex]$\frac{dx}{dt} = \frac{90}{\left(90^2 +90^2\right)^{1/2}} \times 100$[/tex]

[tex]$\frac{dx}{dt} = \frac{90}{\sqrt{8100+8100}} \times 100$[/tex]

[tex]$\frac{dx}{dt} = 50\sqrt2$[/tex]

    = 70.710 ft/s

Answer:

Step-by-step explanation:

Initial value of house:

Yearly increase rate of value:

Time

Since the increase is concerning the current price it would be exponential growth.

The function would be:

For t= 13 we get:

Profit made would be:

Correct option is D.

Answer:

Cost of Tammy's house =$184000

Rate of interest = 3.5% per annum

After 13years price will be

[tex]P(t) = 184000 {(1 + \frac{3.5}{100}) }^{t} \\ P(t) = 184000 {(1 + 0.035)}^{t} \\ P(13) = 18400 {(1.035)}^{13} \\ P(13) =\$ 287768[/tex]

Total profit= $(287767-184000)= $103768
