Answer:

A. 64 trucks and 80 cars

Step-by-step explanation:

The ratio is 4:5 or 4/5, which equals 0.8. Divide the number of trucks by the number of cars to see which other answer equals 0.8. The only one that does is A.

Answer:

hence, she is riding [tex]\frac{2}{15}[/tex] miles per minute

Step-by-step explanation:

The computation of the rate at which she is riding is shown below:

Given that

Rita covered 1 mile in 15 minutes.

And, her covered 3 miles in 30 minutes.

Now

Let us assume the number of miles covered would be in x minutes

So for one miles the point would be (15,1)

And for three miles, the point is (30,3)

Now the slope of the line is

m equal to

[tex]\frac{y_2 - y_1}{x_2 - x_1} \\\\\frac{3 - 1}{30 - 15} \\\\\frac{2}{15}[/tex]

hence, she is riding [tex]\frac{2}{15}[/tex] miles per minute

150 personas respondieron que prefieren el mango verde

Explicación paso a paso:

en un estudio de preferencia entre mango verde y maduro se encuestaron 150 personas 60% prefieren mango verde Cuántas personas respondieron que prefieren mango verde

paso uno:

datos dados

número total de personas encuestadas = 150

60% mango preferido

esto significa que 150 personas son 100%

y deja que X personas sean 60%

X = (60 * 150) / 100

X = 90

Puede verificarlo tomando el 60 por ciento de 150 de esta manera:

150 * 60/100 = 90

Answer:

After 8 weeks, Faith would have $88. money saved = 40+6w

Answer:

$88 saved in 8 weeks

Step-by-step explanation:

Part 1:

You would first set up the equation 40 + (6 x 8) = t. T would be the total money saved. You would then do 6 times 8 first, as they're in parenthesis. You would get 48. You now have 40 + 48 = t. You would now add like terms, and you would get 88 = t. You would save $88 in 8 weeks.

Part 2:

40 + 6w = t

w would represent the number of weeks, t would represent the total number of money saved.

Answer:

3 + 2b

Step-by-step explanation:

To simplify, you have to combine (add) like terms. The like terms are 5 and -2 because they both do not have a variable.

5 + (-2) = 3

2b stays the same because there are no like terms for it.

3 + 2b

Step-by-step explanation:

Hope this helps.

Step-by-step explanation:

The question is not well written. Let us say the function given as expressed as;

f(x) = -1/x + 3/x⁴

f'(x) means we are to differentiate the function with respect to x;

Given f(x) = axⁿ

f'(x) = naxⁿ⁻¹

f(x) = -x⁻¹ + 3x⁻⁴

Applying the differentiation formula we will have;

f'(x) = -1(-x⁻²)+(-4)3x⁻⁴⁻¹

f'(x) = x⁻²-12x⁻⁵

Express as a fraction

f'(x) = 1/x²-12/x⁵

To get f'(4), we will have to substitute x = 4 into the resulting expression

f'(4) = 1/4²-12/4(5)

f'(4) = 1/16-12/20

f'(4) = 1/16-3/5

Find the LCM

f'(4) = (5-48)/80

f'(4) = -43/80

Note that the function used was assumed but the same method can be employed to any other functions.

Answer:

Volume = Length × Width × Height

Step-by-step explanation:

A right rectangular prism is a three-dimensional object like the one shown in the attachment. It has dimensions: Length, Width and Height. All the angles between the sides are 90°. In order to calculate the volume of an object shaped like a  right rectangular prism, we use the following expression.

Volume = Length × Width × Height

Smallno. =16

Bug no. =36

Step-by-step explanation:

Y=big number

X=small number

X+Y=52

Y=2X+4

Substitute

X+2X+4=52

3X=48

X=16(small no.)

Y=36(large no.)

Checking:

36+16=52(yay correct)

36=(2*16)+4 (coorrectoo!)

Answer:

330,750 people

Step-by-step explanation:

If the population increases by 5% every year, in 2 years the population of the city will be 330,750 people. D is also the correct answer as shown in the file.

Population after 2 year is 330,750

Given that;

Growth rate = 5% = 0.05

Current population = 300,000

Find:

Population after 2 year

Computation:

Population after 2 year = 300,000(1 + 0.05)²

Population after 2 year = 300,000(1.05)²

Population after 2 year = 330,750

Answer:

[tex]\%Increase = 4\%[/tex]

Step-by-step explanation:

Given

[tex]Initial\ Population = 625[/tex]

[tex]Final\ Population = 650[/tex]

Required

Determine the percentage population increase

This is calculated using the following formula:

[tex]\%Increase = \frac{Final - Initial}{Initial} * 100\%[/tex]

[tex]\%Increase = \frac{650 - 625}{625} * 100\%[/tex]

[tex]\%Increase = \frac{25}{625} * 100\%[/tex]

[tex]\%Increase = \frac{25* 100\%}{625}[/tex]

[tex]\%Increase = \frac{2500\%}{625}[/tex]

[tex]\%Increase = 4\%[/tex]

Hence, there is a 4% increment from 2014 to 2015
