Answer:

10

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 5x + 10 ← is in slope- intercept form

with y- intercept c = 10

$3.98 + $2.75 + $ 3.87 = $10.60

Answer:

She will be ready, and she will make it on time.

Step-by-step explanation:

Given:

[tex]Start\ Time = 10:20\ am[/tex]

[tex]Planting = 5\ hours[/tex]

[tex]Shower = 1\ hour[/tex]

Required

Will she be ready by 5pm?

First, we calculate the time spent in planting and taking shower.

[tex]Time\ Spent = Planting + Shower[/tex]

[tex]Time\ Spent = 5\ hours + 1\ hour[/tex]

[tex]Time\ Spent = 6\ hours[/tex]

Next, we calculate the end time. i.e. the time she'll finish these tasks.

[tex]End\ Time=Start\ Time + Time\ Spent[/tex]

[tex]End\ Time=10:20\ am + 6\ hours[/tex]

[tex]End\ Time=04:20\ pm[/tex]

Since 04:20 pm is less than 5pm, then she will be ready, and she will make it on time.

Step-by-step explanation:

12 x 3 is 36, he has 33 dollars

answer

15.5%

Step-by-step explanation:

length = 30

30+10%=33

breadth=20

20+5%=21

area of rectangle = length × breadth

600² centimeters = 30 × 20

693² centimeters = 33 × 21

Increase = 15.5%

Answer:3.86 m

Step-by-step explanation:

Given

Length of ladder L=4 m

angle made by ladder and the ground is [tex]\theta=75^{\circ}[/tex]

we will use trigonometry here

from the figure, we can write

[tex]\sin 75^{\circ}=\dfrac{x}{L}\quad [\text{where, x=distance of the ladder from the ground}][/tex]

[tex]\Rightarrow x=L\sin 75^{\circ}\\\Rightarrow x=4\sin 75^{\circ}=3.86\ m[/tex]

Answer:

The pair of expressions in the options 'b' and 'c' is equivalent using the Associative Property of Multiplication.

Hence, options b and c are correct.

Step-by-step explanation:

The associative property of multiplication defines that when we multiply, we can group the numbers in any combination.

a × (b × c) = (a × b) × c

For example,

4 × (6 × 8) = (4 × 6) × 8

In our case, now, if we analyze the options 'b' and 'c'

5 (3a · 4) = (3a · 4) · 5

5 (3a · 4) = (5 · 3a) · 4

It is clear that both the expressions are equivalent using the Associative Property of Multiplication as we have discussed earlier.

Thus, the pair of expressions in the options 'b' and 'c' is equivalent using the Associative Property of Multiplication.

Hence, options b and c are correct.

Answer:

We conclude that it is possible for an object to have more than one input value, but only one output value.

Step-by-step explanation:

Yes, it is possible for an object to have more than one input value, but only one output value.

For example, considering the table having 'name' as the 'input' and the output as 'age'.

Name of Relatives                Age (years)

Mr A                                       13

Mr B                                       14

Mr C                                       13

Mr D                                       15

Here, Each input has only input. But, multiple relatives can have the same age.

Here, Mr A and Mr C have the same 13 years age. This table represents a function.

Therefore, we conclude that it is possible for an object to have more than one input value, but only one output value.

Answer:

x=13/4

Step-by-step explanation:

4x+5=18....collect like terms

4x=18-5

4x=13

x=13/4 or 3.25

Answer:

The like terms would be 3x and -3x.

Step-by-step explanation:

If you add the like terms together you would get 0x and be left with -2y.

Answer:

Jo earned a profit of $2500.

Step-by-step explanation:

Given that:

Selling price of 5000 gallons = $1 per gallon

Total selling price = 1 * 5000 = $5000

Production cost = 50 cents per gallon = $0.5 per gallon

Total production cost = 0.5 * 5000 = $2500

Production cost < Selling cost

Therefore,

Jo earned profit on gasoline.

Profit = Selling cost - Production cost

Profit = 5000 - 2500

Profit = $2500

Hence,

Jo earned a profit of $2500.

Answer:

  (a)  -2

Step-by-step explanation:

Put -1 where x is and do the arithmetic.

  f(x) = x³ +2x² -3

  f(-1) = (-1)³ +2(-1)² -3

  f(-1) = -1 +2 -3 = 1 -3

  f(-1) = -2

Answer: The answers are:

6 + 2 = 8

4 + (-1) = 3

Step-by-step explanation:

Add 6 by 2.

Solve for X.

4 + X = 3

To find X, we use the integer rule. We can use this:

Positive and Positive =  Positive

Negative and Negative = Negative

Positive and Negative = Both (It depends if the negative or positive is larger than the other)

For this problem, we can use: Positive and Negative = Both.

If we look at the chart, we can see 4 and 3. How can we get 4 + ? = 3? We can use the integer, -1. Since we said, Positive and Negative = Both, we must compare the positive-addend (4) by the negative-addend (-1).

4 is greater than -1

4 > -1

Therefore, X equals -1.

4 + (-1) = 3

Answer: 8, -1

Step-by-step explanation:

The table shows some addition problems.  Each column is its own problem, with the first two rows being addends and the bottom row being the sum.  Thus, simply do 6+2 to get the first blank(left-to-right), 8.  Then, do 4+x=3 to get the second blank, or -1.

Answer:

Step-by-step explanation:

Find the discounted price by setting up an equation

40-.3(40) AKA 30% of the original price is being taken off of the original price

Evaluate

40-12

$28 = discounted price

Sales tax is based on the reduced/discounted price* remember this

OF= multiplication (in this scenario)

.08x28

$2.24= sales tax

Add tax with discounted price

28+2.24=
