Answer:

20

Step-by-step explanation:

Given :

Length = l

Width = w

Area of square = 45

Let side of square = x

Area of square = x²

45 = x²

√45 = x

l of rectangle = x + 5 = √45 + 5

w of rectangle = x -5 = √45 -5

Area of rectangle= l * w

Area = (√45 + 5) * (√45 - 5)

Area = 45 - 5√45 + 5√45 -25

Area = 45 -25

Area of rectangle = 20

Answer:

60% of 45 =  0.6 × 45 = 27

25% of 80 =  0.25 × 80 = 20

16% of 40 = 0.16 × 40 = 6.4

The second question:

Consider the division expression [tex]7\frac{1}{2} / 2[/tex]. Select all multiplication equations that correspond to this division expression.

[tex]2 * ? = 7\frac{1}{2}[/tex]     [tex]7\frac{1}{2} * ?= 2[/tex]     [tex]? * 2 = 7\frac{1}{2}[/tex]

[tex]2* 7\frac{1}{2} = ?[/tex]    [tex]? * 7\frac{1}{2} = 2[/tex]

Answer:

1. See Explanation

2. [tex]2 * ? = 7\frac{1}{2}[/tex]     and     [tex]? * 2 = 7\frac{1}{2}[/tex]

Step-by-step explanation:

Solving (a):

Given

[tex]Students = 60[/tex]

[tex]Group = Equal\ Sized[/tex]

Required

Interpret [tex]\frac{60}{5}[/tex] in 2 ways

Interpretation 1: Number of groups if there are 5 students in each

Interpretation 2: Number of students in each group if there are 5 groups

Solving the quotient

[tex]Quotient = \frac{60}{5}[/tex]

[tex]Quotient = 12[/tex]

For Interpretation 1:

The quotient means: 12 groups

For Interpretation 2:

The quotient means: 12 students

Solving (b):

Given

[tex]7\frac{1}{2} / 2[/tex]

Required

Select all equivalent multiplication equations

Let ? be the quotient of t [tex]7\frac{1}{2} / 2[/tex]

So, we have:

[tex]7\frac{1}{2}/2 = ?[/tex]

Multiply through by 2

[tex]2 * 7\frac{1}{2}/2 = ? * 2[/tex]

[tex]7\frac{1}{2} = ? * 2[/tex]

Rewrite as:

[tex]? * 2 = 7\frac{1}{2}[/tex]  --- This is 1 equivalent expression

Apply commutative law of addition:

[tex]2 * ? = 7\frac{1}{2}[/tex]  --- This is another equivalent expression

Answer:

40.5

Step-by-step explanation:

Since the centroid (the point of concurrency of the sides of a triangle) divides the 3 medians into the ratios from the point to the centroid to the centroid to the side into the ratio of 2:1. To find PK divide 27 by 2

27/2=13.5

Then add 27 and 13.5 to get KL

27+13.5=40.5

Answer:

-41

Step-by-step explanation:

Both 9/3 and 54/18 come out to 3, so your answer is:

18:54

Answer:

18:54

Step-by-step explanation:

We have to simplify these ratios.

If the most simplified form of the ratios are equal, they are equivalent

3:9

24:54

18:54

Same ratio as 3:9, so 18:54 is equivalent to 3:9

36:81

Answer:

-16

Step-by-step explanation:

The equation for a slope is rise/run. You know from the question that the slope is -4/5 in its simplest form. However, the run in its original form is 20.

So if the run is 5 in its simplest form, but 20 in its original form, then this means the slope must have been simplified by dividing both the original rise and the original run by 4, because 20/4 = 5.

That also means we can find out the original rise by doing the inverse of what we did above. We can multiply the rise in its simplest form by 4 to get the original. That gives us -16 (because -4*4 = -16).

Answer:

1 hour and 30 minuets

Step-by-step explanation:

Answer:

a = 1, b = 3, c = 1, d = 2, e = 6, and f = 8

Step-by-step explanation:

The given exponential functions are;

2ˣ, 3·2ˣ, and  [tex]2^{3 \cdot x}[/tex]

Let f(x) = 2ˣ, h(x) = 3·2ˣ, and g(x) = [tex]2^{3 \cdot x}[/tex]

From the table for investigating the dilations of exponential function, we have;

a = f(0) = 2⁰ = 1

b = h(0) = 3·2⁰ = 3 × 1 = 3

c = g(0) = [tex]2^{3 \times 0}[/tex] = 2⁰ = 1

d = f(1) = 2¹ = 2

e = h(1) = 3·2¹ = 3 × 2 = 6

f = g(1) = [tex]2^{3 \times 1}[/tex] = 2³ = 8.

30 girls

Step-by-step explanation:

Every 10 girls there are 7 boys.

So if there are 3 groups of 7 boys, there will be 30 girls.

Check:

10 girls: 7 boys

+10 girls: 7 boys

+10 girls: 7 boys

= 30 girls: 21 boys

Answer:  B) -$75.00

========================================================

Explanation:

Draw a vertical number line. Plot 40 on this line. Then move down 85 units to arrive at 40-85 = -45. The negative indicates that you're in debt.

Then move down another 30 due to the overdraft fee and we have -45-30 = -75 as the bank balance.

-------------------

Put another way:

Start at $40. If you spend $40, then your balance is $0. You need to spend another $45 to get all of the groceries (since the grocery bill is 40+45 = 85 dollars). That's where the -45 comes from, to indicate you're 45 dollars in debt. This is before the overdraft fee kicks in. Adding on that fee gets a total debt of 45+30 = 75 dollars. So that's why the final balance is -75 dollars.

Step-by-step explanation:

cost of 18 apples= 18x6p= 108p

£5-108p= x (will let it be x since i do not know the conversion)

maximum number of banana he can buy= x divide by 40p (rounded down to smallest whole number)= b

The change he have= x-(40×b) = y

apples bought with change= y divide by 6p= a

do the working above to find value for a and b, add a to the 18 apples bought initially and b is number of banana

Answer:

8f + 2t = $135 - - (1)

6f + 4t = $110 - - (2)

$16

Step-by-step explanation:

Given that:

f = dog food

t = dog treat

8f + 2t = $135 - - (1)

6f + 4t = $110 - - (2)

From (1)

4f + t = 67.5

t = 67.5 - 4f

Put t = 67.5 - 4f in (2)

6f + 4(67.5 - 4f)= 110

6f + 270 - 16f = 110

-10f = 110 - 270

-10f = - 160

f = 16

One bag of dog food = $16
