Answer: £516

Step-by-step explanation:

7.5 increase = 100 + 7.5 = 107.5

107.5/100 = 1.075 (multiplier)

480 x 1.075 = 516

Answer:

1

Step-by-step explanation:

The coefficient is the number in front of a variable. There is a hidden coefficient of 1 in front of z. The reason it is not shown is because any number multiplied by 1 is just that number so showing the 1 is redundant.

The coefficient  of z in the expression 3x- 4y +z is 1.

A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:

Given:

3x - 4y + z

As, we know a coefficient is a number that is multiplied by a variable.

So, the coefficient of x is 3, coefficient of y is 4 and coefficient  of z is 1.

Answer:

89 km/hr

Step-by-step explanation:

Distance = Rate(speed) × Time

D = R × T

T = 4 hours

One car's rate is 12 kilometers per hour less than the other's.

Hence:

First's car's rate = r × 4 = 4r

Second car's distance = (r + 12) × 4 = 4r + 48

4r + 4r + 48 = 760

8r + 48 = 760

8r = 760 - 48

8r = 712

r = 712/8

r = 89 km/hr

The rate of the slower car is 89 km/hr

Answer:

D.72

Step-by-step explanation:

Answer:

no, 72 km/hr is equal to 20m per sec

Step-by-step explanation:

20 m = .02 km

.02 km per hour is equal to .02(3600) per hour, which is 72 km per hour

(you have to multiply my 3600 to get seconds into hours)

Answer:

3 1/3 feets

Step-by-step explanation:

Given that:

Height of aquarium = 1 3/4 feets

Area of aquarium = 5 5/6 ft²

The length of aquarium = x

Aquarium is shaped in the form of a rectangle :

Area of a rectangle = Length * width

5 5/6 = x * 1 3/4

35/6 = 7x/4

Cross multiply :

7x * 6 = 35 * 4

42x = 140

x = 140 / 42

x = 3 14/42

x = 3 1/3 feets

Hence, Length of the back of aquarium is 3 1/3 feets

In choice a:

Both children between 5 and 15 years old and 160 years old are also the populations of interest, and Kids from 5 to 15 years of age.

In choice b:

These findings could be compared like we do not know whether the groups were randomly selected, and the allocation is still not random; there could be no casual conclusion because the statement is valid even With sample research, and after randomization, filtering, and testing of 160 specimens (instruction vs no-instruction) Its analysis can be common to the community and replicated. There could be explanatory relations generated by experimental research. This analysis is observational and can therefore be used Causal relationships are established.gggg

Answer:

2/11

Step-by-step explanation:

Here we have two mixed numbers. Be very careful when handeling negative mixed numbers. Don't coonfuse "-3 2/11" with "-3 + 2/11"

4 2/5 + k = -3 2/11

I add a minus into the mixed fraction on the right. Of course you don't have to write an entire new line when you do calculations on paper.

4 2/5 + k = -3 -2/11

k = - 3 - 4 - 2/5 - 2/11

k= - 7 -2/5 -2/11

Make common denominators. Both 11 and 5 is prime numbers (numbers that are only divisible by one and itself). Therefore the common denominator is 5*11=55.

k= - (7*55)/55 - (2*11)/(5/11) - (2*5)/(11*5)

k = - 385/55 - 22/55 -10/55

k = - (385 +22+10)/55

k = - 417/55

Since 417 isn't divisible by neither 11 nor 5, this fraction is in it's simplest form.

Answer:

3/2x²yz – 9/8xyz + 15/4xy = 3/2xy[xz – 3/4z + 5/2)

Step-by-step explanation:

Given 3/2x²yz – 9/8xyz + 15/4xy. Let's look for a common factor.

3/2x²yz = 3/2 * x * y * z

9/8xyz = 3/2 * 3/4 * x * y * z

15/4 = 3/2 * 5/2 * x * y

Looking at the above; 3/2, x and y are common to all terms. Therefore the factor is:

3/2xy. Now let's factor it from each term

3/2x²yz = 3/2xy(xz)

9/8xyz = 3/2xy(3/4z)

15/4xy = 3/2xy(5/2), therefore we have:

3/2x²yz – 9/8xyz + 15/4xy = 3/2xy[xz – 3/4z + 5/2).

Answer: $65

Step-by-step explanation:

The store is having a 20% off sale.

Mai buys an item and saves $13.

This means that $13 is 20% of the price of the item that Mai bought.

Assume the original price is x. Expression is:

x * 20% = 13

x = 13/20%

x = $65

Answer:

The rate of change is 1

Step-by-step explanation:

Given

[tex]\{[3, 4], [4, 5], [5, 6]\}[/tex]

Required

Predict the rate of change

Average rate of change (R) is calculated using:

[tex]R = \frac{f(b) - f(a)}{b - a}[/tex]

Here, we have:

[tex][a,f(a)] = [3,4][/tex] and

[tex][b,f(b)] = [5,6][/tex]

Substitute these values in the above equation

[tex]R = \frac{6 - 4}{5 -3}[/tex]

[tex]R = \frac{2}{2}[/tex]

[tex]R = 1[/tex]

Also, check the rate of change using:

[tex][a,f(a)] = [3,4][/tex] and

[tex][b,f(b)] = [4,5][/tex]

The equation: [tex]R = \frac{f(b) - f(a)}{b - a}[/tex] becomes

[tex]R = \frac{5-4}{4-3}[/tex]

[tex]R = \frac{1}{1}[/tex]

[tex]R = 1[/tex]

Hence, the rate of change is 1

Given:

The graph of a line.

To find:

The y-intercept of the line.

Solution:

y-intercept of a line is the point at which the line intersect the y-axis.

We have, graph of the line.

From the given graph it is clear that the line intersect the y-axis at (0,4).

So, y-intercept is at point (0,4).

y-intercept = 4

Therefore, the y-intercept is 4.

log5 (4/7)= log5 (4)- log5 (7)=-0.347708839

Step-by-step explanation:

for the first question which would be Approximate: log5 4/7 the answer would be B. –0.3477

and for the second question which would be Approximate: log1/2 5 the answer would be C.–2.3219

Step-by-step explanation:   Using Properties of Logs

logb(x/y) = logbx - logby.

Furthermore

log5 (4/7)= log5 (4)- log5 (7)

Solve log 5 (4) and log 5 (7)  with the base change of the logarithm

log 5 4 = log 4 / log 5

Use the calculator (DESMOS):  log 5 4 =0.8613531161

log 5 7 = log 7 / log 5

log 5 7 =1.2090619551

Therefore, The answer is, log5 (4/7)= log5 (4)- log5 (7)=-0.347708839
