Daily Payment = 5h+8

Step-by-step explanation:

Here we are given that in seven days the amount Harriet earned is given as

35h+56

It is also given that the amount earned each day is same.

We have to determine the amount earned each day. Total number of days is 7 . Hence in order to find the daily earning we divide the total earning by 7

Daily earning =

[tex]E=\frac{35h+56}{7}\\E=\frac{7(5h+8)}{7}\\E=5h+8[/tex]

Hence answer is 5h+8

The slope of the line passing through points is undefined.

The slope or gradient of a line is a number that describes both the direction X and Y and the steepness of the line. It is the ratio of the vertical change to the horizontal change between any two distinct points on a line.

For the given situation,

The line passing through points (x1, y1) is (-6, 3) and (x2,y2) is (-6, 39)

The formula of slope of line is

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

⇒ [tex]m=\frac{39-3}{-6-(-6)}[/tex]

⇒ [tex]m=\frac{39-3}{-6+6}[/tex]

⇒ [tex]m=\frac{39-3}{0}[/tex]

⇒ [tex]m=\infty[/tex]

Since x1 = x2, there is no horizontal change. The line passes as a straight line.

Hence we can conclude that the slope of the line passing through points is undefined.

The two positive numbers are 10 and 5.

Given that,

The difference between two positive numbers is 5.

And the sum of their squares is 125.

Let us assume that,

The numbers are x and y.

Here, the difference between two positive numbers is 5.

x - y = 5

x = 5 + y  .. (i)

And, the sum of their squares is 125.

That is,

x² + y² = 125

Substitute the value of x from (i);

(5 + y)² + y² = 125

25 + y² + 10y + y² = 125

2y² + 10y + 25 = 125

2y² + 10y - 100 = 0

2 (y² + 5y - 50) = 0

y² + 5y - 50 = 0

y² + (10 - 5)y - 50 = 0

y² + 10y - 5y - 50 = 0

y (y + 10) - 5 (y + 10) = 0

(y - 5) (y + 10) = 0

This gives,

y = 5

y = - 10

Since the numbers are positive.

Hence, y = - 10 is not possible.

From (i);

x = 5 + y

Put y = 5;

x = 5 + 5

x = 10

Hence,

The two positive numbers are 10 and 5.

Answer:

Distribute 2 inside the parenthesis

Step-by-step explanation:

Julie started solving the equation

3x=4+2(3−x)

To simplify any expression we use order of opeation PEMDAS

Always start simplifying the parenthesis

To remove parenthesis we apply distributive property

Distribute 2 inside th4e parenthesis

3x=4+2(3−x)

3x=4+6-2x

So next step is distributing 2 inside the parenthesis

3x=4+6-2x

According to the given statement, we can get the equation:

50 - 3x = 1/2 (50-x)

where x = amount removed from bag two, 3x removed from bag one

Then we multiply both sides by 2 (to eliminate the ½)

100-6x= 50-x

Add 6x to both sides

100= 50-5x

Then subtract 50 from both sides

50=5x

Lastly, divide by 5

10=x

Therefore 10 kg of sugar was removed from bag 2

further, 3x= 30, so 30 kg of sugar was removed from bag 1.

50-30=20 kg remaining in bag 1.

50-10=40 kg remaining in bag 2.

Answer:

40 kg in the first bag, 80 in the second

Step-by-step explanation:

The number of different ways this order can be filled is:

                              13 ways.

A customer ordered fourteen zingers.

zingers are placed in packages of​ four, three, or one.

Case-1

If the number of packages of four are: 3

Then 4×3=12 zingers.

a)

So, there will be zero packet of 3.

and 2 packs of 1.

Since, 12+2×1=14

Case-2

If the number of packages of four are: 2

i.e. 4×2= 8 zingers.

a)

If number of packages of 3 are: 2

i.e. 3×2=6

then number of package of 1 have to be 0.

b)

If number of packages of 3 are: 1

i.e. 3×1=3 zingers

Number of packages of 1 zinger will be: 3

i.e. 8+3+3=14

c)

If number of packages of 3 are: 0

Then number of packets of 1 will be:  6

Case-3

If the number of packages of four are: 1

a)

If number of packages of 3 are: 3

i.e. 3×3=9 zingers.

Hence, number of packets of 1 have to be: 1

b)

If number of packages of 3 are: 2

i.e. 3×2=6 zingers

Then number of packets of 1 have to be: 4

c)

If number of packages of 3 are: 1

i.e. 3×1=3 zingers

Then number of packets of 1 have to be: 7

d)

If number of packages of 3 are: 0

i.e. 3×0=0 zingers

Then number of packets of 1 have to be: 10

Case-4

If the number of packages of four are: 0

a)

If number of packages of 3 are: 4

i.e. 3×4=12 zingers

Then number of packets of 1 have to be: 2

b)

If number of packages of 3 are: 3

i.e. 3×3=9 zingers

Then number of packets of 1 have to be: 5

c)

If number of packages of 3 are: 2

i.e. 3×2=6 zingers

Then number of packets of 1 have to be: 8

d)

If number of packages of 3 are: 1

i.e. 3×1=3 zingers

Then number of packets of 1 have to be: 11

e)

If number of packages of 3 are: 0

i.e. 3×0=0 zingers

Then number of packets of 1 have to be: 14

There are total 13 ways of doing so.

( 1 from case-1

3 from case-2

4 from case-3

and 5 from case-4

i.e.  1+3+4+5=13 ways )

The order can be filled in 5 different ways by using packages of 4, 3, or 1 zingers.

To find the number of different ways the order can be filled, we can use the concept of permutations and combinations. Since zingers can be placed in packages of 4, 3, or 1, we need to find all the possible combinations of these packages that add up to 14.

Therefore, the total number of different ways the order can be filled is 2 + 2 + 1 = 5.

Answer:

20 and 30. that's your answer.

Step-by-step explanation:

we have

m∠P=[tex](2x)\°[/tex]

m∠Q=[tex](4x)\°[/tex]

m∠R=[tex](6x)\°[/tex]

1) By the triangle sum theorem, the sum of the angles in a triangle is equal to [tex]180\°[/tex]

therefore

m∠P+m∠Q+m∠R=[tex]180\°[/tex]

we know that

Substitution Property of Equality, states that If the values of two quantities are known to be equal, you can replace the value of one quantity with the other

so

2) Using the Substitution Property of Equality

[tex](2x)\°+(4x)\°+(6x)\°=180\°[/tex]

Simplifying the equation gets

[tex](12x)\°=180\°[/tex]

3) using the division property of equality

The Division Property of Equality states that if you divide both sides of an equation by the same nonzero number, the sides remain equal

[tex](12x)\°/12=180\°/12[/tex]

[tex]x=15\°[/tex]

therefore

the answer is

Part a) Substitution Property of Equality

Part b)  [tex]x=15\°[/tex]

Answer:

Part a) Substitution Property of Equality

Part b) x=15

Step-by-step explanation:

Given triangle PQR with

[tex]m\angle P=(2x)^{\circ}[/tex]

[tex]m\angle Q=(4x)^{\circ}[/tex]

[tex]m\angle R=(6x)^{\circ}[/tex]

By the triangle sum property, the sum of the angles of a triangle is equal to [tex]180^{\circ}[/tex]

∴ m∠P+m∠Q+m∠R=180°

Substitution Property of Equality, states that If the values of two quantities are known to be equal, one can replace the value of one quantity with the other

[tex](2x)^{\circ}+(4x)^{\circ}+(6x)^{\circ}=180^{\circ}[/tex]

Simplifying the equation we get

[tex](12x)^{\circ}=180^{\circ}[/tex]

Using the division property of equality

The Division Property of Equality states that division with the same non zero number results that both sides remain equal

[tex]\frac{(12x)^{\circ}}{12}=\frac{180^{\circ}}{12}[/tex]

[tex]x=15[/tex]

Hence, the answer is

Part a) Substitution Property of Equality

Part b) x=15

Final answer:

The expression log3 6 can be converted to a logarithm of base 2 using the change of base formula, which results in log2 6 / log2 3. So the correct option is b.

Explanation:

The student asked how to express log3 6 as a logarithm with a base of 2. To perform this conversion, we can use the change of base formula, which states that logab = logcb / logca for any positive numbers a, b, and c, where a and c are not equal to 1. In this formula, 'c' can be any base, but in our case, we will use base 2 since that's what the question requires.

So, by applying the change of base formula, we can write:

Therefore, the correct option that represents log3 6 as a logarithm of base 2 is:

The correct choice is D, where 'If next month is January' is the hypothesis, and 'then this month is the last of the year' is the conclusion, demonstrating the proper format and identification of a true conditional statement.

The question is concerning a true conditional statement and the identification of its hypothesis and conclusion. To form a proper conditional, we use the format 'If... then...' where the 'if' part represents the hypothesis and the 'then' part represents the conclusion. The hypothesis is the supposed condition, while the conclusion is the result or outcome that follows from the hypothesis.

Let's analyze the choices:

Choice A has the conclusion and hypothesis reversed.

Choice B is an incorrect format for a conditional because it uses 'so' instead of 'if... then...'.

Choice C has the same issue as choice B.

Choice D is in the correct format and has the hypothesis and conclusion properly identified. If next month is January is the hypothesis, and then this month is the last of the year is the conclusion.

Therefore, the answer is Choice D.
