Answer 1

Answer: 71/28 or 2 15/28

Step-by-step explanation:

Turn both fractions into improper fractions.

5 1/4 = 21/4

2 5/7 = 19/7 multiply the denominator with the whole then add the numerator, same denominator.

21/4 - 19/7 = ? find common denominator to subtract

4 x 7 = 28 common denominator

Divide the new denominator by previous denominators then multiply by each respective numerator. 28 divided by 4 is 7 multiplied by 21 is 147, the same happens with 19/7.

147/28 - 76/28 = 71/28 or 2 15/28

In circle J with the measure of minor arc \stackrel{\Large \frown}{HK}=58^{\circ}, HK ⌢ =58 ∘ , find \text{m} \angle HLK.m∠HLK

Answers

By applying the central angle property, the measure of angle HLK is equal to 29°.

What is the central angle property?

The central angle property states that an inscribed angle is equal to half the measure of a central angle that is subtended by the same arc.

This ultimately implies that, a central angle is double (twice) the measure of an inscribed angle that is subtended by the same arc.

By applying the central angle property, we have:

HK = 2m∠HLK

58 = 2m∠HLK

m∠HLK = 58/2

m∠HLK = 29°.

Triplets Peter, Reeta and Nikita have two ways for getting home from school each day: cycle on a tandem bike or walk. The bike can carry either one or two riders at a time. Regardless of the number of people pedalling, cycling speed is 5 times walking speed. The triplets always leave school at the same time and always use the same path between school and home, whether walking or cycling. The school is 5km from home and their walking speed is 4 kilometres per hour.

d) On Thursday, it is Reeta's turn to walk. Peter drops Nikita off at a certain point leaving her to walk home, Meanwhile he returns to pick up Reeta and they cycle home together. If all three arrive home at the same time, how far from school are the drop-off ad pick up points.

Answers

Answer:

Pick up point is 1.43 km from the school and drop point is 3.57 km from the school ( to the nearest hundredth).

Step-by-step explanation:

School <----------- 5 km ---------------> Home

_______ P _______ D _______

x km y km 5-x-y km

_______

_________________

5-x km

D is the point where Peter drops off N and P is the pick point x km from the school where Peter picks up R. He travels back y km to pick up R.

We work in times:

Time = distance / speed

The time that R walks from the school to point P is the same as Peter travels the distance (x + 2y) km, so we have

x/5 = (x + 2y)/20

20x = 5x + 10y

15x - 10y = 0 A

The time that N walks home equals the time that Peter travels y + 5 - x km.

So (y + 5 - x)/20 = (5 - x - y)/5

5y + 25 - 5x = 100 - 20x - 20y

15x + 25y = 75

3x + 5y = 15 B

Solving equation A and B

15x - 10y = 0

3x + 5y = 15

Multiply the second equation by 2:

6x + 10y = 30

Adding this to the first equation

21x = 30

x = 30/21 = 1.4285

So 3(1.4285) + 5y = 15

y = 2.1428

Pick up x = 1.43 km

and the drop is 1.43 + 2.14 = 3,57 km from the school

Lorenzo increases all the prices on his restaurant menu by 8%
After the increase, the price of lasagne is £9.45
Work out the price of lasagne before the increase.

Answers

Step-by-step explanation:

to add 8% the simplest operation is to multiply the basic amount by 1.08.

so,

£9.45 = original price × 1.08

original price = £9.45/1.08 = £8.75

the price before the increase was £8.75.

The quotient of (x⁴ - 3x² + 4x - 3) and (x² + x - 3) is x² - x + 1

How to determine the quotient?

The quotient expression is given as:

(x⁴ - 3x² + 4x - 3) ÷ (x² + x - 3)

Find the value of x in the equation without evaluating the power

Answers

Answer:

See below

Step-by-step explanation:

2 ^(5+x) = 2^8 (because 256 = 2^8)

equate the exponents 5+x = 8 then x = 3

1/3 ^(2+x) = 1 / 3^ 6 (because 729 = 3^6 )

equate the exponents 2+ x = 6 then x = 4

Answer:

a) x = 3

b) x = 4

Step-by-step explanation:

Use the Exponential Power Rule.

[tex]a^x \times a^y = a^{x+y}[/tex]

Also covert the term on the right to the same base as on the left.

If you are allowed to have calculator do [tex]\log_{\text{base}} (\text{number})[/tex] to get the exponent. For example [tex]\log_{2} (256) = 8[/tex], that means [tex]256 = 2^8.[/tex]

Without calculator you can divide with base untill you have it fully factored, then count. For example:

256/2 = 128
128/2 = 64
64/2 = 32
32/2 = 16
16/2 = 8
8/2 = 4
4/2 = 2
2/2 = 1

We had to divide with base two 8 times so 256 = 2⁸.

[tex]2^5 \cdot 2^x = 256\\2^{5+x} = 2^8[/tex]

Now that we have same base we can equate the exponents!

[tex]5 + x = 8\\x = 8 - 5\\x = 3[/tex]

[tex](\frac{1}{3})^2 \cdot (\frac{1}{3})^x = \frac{1}{729}\\\\(\frac{1}{3})^{2+x} = \frac{1}{3^6}\\\\(\frac{1}{3})^{2+x} = (\frac{1}{3})^6[/tex]

[tex]2 + x = 6\\x = 6 - 2\\x = 4[/tex]

Every variable has a coefficient. Thats the number it is multiplied by. According to mathematical convention, coefficients always go in front of their variable.
