On the block where Liza lives, the house numbers of all the two-story homes are prime numbers. Liza's block contains house numbers between 40 and 60. List all of the house numbers of all the houses that you know have two stories.

Answers

Answer 1

Answer:

Answer:

41, 43, 47, 53, 59

Step-by-step explanation:

Prime numbers are numbers that can be divided only by 1 and itself.i.e. it has only two factors. 1 is not a prime number as it has only one factor. The Prime numbers between 40 and 60 are 41, 43, 47, 53, 59.

The two-story home numbers are 41, 43, 47, 53, 59.

D. (0,4)

Answers

Answer:

(0,-4)

Step-by-step explanation:

The x coordinate comes first in the ordered pair

We do not move left or right from the origin so the x coordinate is zero

The y coordinate is second, we move 4 units down so the y coordinate is negative 4

The ordered pair is (0,-4)

0,-4 coordinates of point A

max and some friends shared the cost of a meal. The meal cost $51 and each person contributes $17. How many people share the cost meal?

Answers

Answer:

3 people

Step-by-step explanation:

$51/$17 = 3 people

- We know to start with $51 dollars because that is the total price of the meal.

- We also know each meal costs $17.

- Next, ask youself what we are trying to find? We are trying to find how many people are eating.

- Therefore to find that we need to take our starting amount $51 divided by $17 because that is the cost of 1 meal.

- $51/$17 = 3 people (whole cost/individual cost = # of people)

- To check this take 3 x 17 = 51 (Now we know it is correct)

Suppose that w and t vary inversely and that t = 5/12 when w= 4. Write a function that models the inverse
variation and find t when w = 5.
A. T=5/12w; 5/12
B.t=5/3w;1/3
C.t=5/48w;5/192
D.t=5/12w;1/3

Answers

Answer:

Option B. t=5/3w ;1/3

Step-by-step explanation:

We are told that $w$ varies Inversely with $t$ thus generally speaking $w$ ∝ $(1)/(t)$ since they are inverted, otherwise if they were proportionally varied then $w$ ∝ $t$ . This means that there is a constant value ( $a$ ) for which $w$ is inversely proportional to $t$ and can be mathematically expressed as:

$w=(a)/(t)$ Eqn. (1)

Now since we are given the values of $w=4$ and $t=(5)/(12)$ , we can plug them in Eqn. (1) and find our constant of proportionality $a$ as follow:

$w=(a)/(t)\n \na=wt\n\na=(4)((5)/(12) )\n\na=(5)/(3)$

Now that we have our constant we can find the new $t$ value for the second value of $w=5$ as follow:

$w=(a)/(t) \n\nt=(a)/(w)\n \nt=((5)/(3) )/(5)\n\nt=(5)/(15)\n \nt=(1)/(3)\n$

Therefore based on the options give, we can see that Option B. is correct since

$t=(5)/(3w)$ and for $w=5$ , then $t=(1)/(3)$

a standard equation follows the form Ax + By = C, so the answer is -0.81x + y = 25 just by subtracting the x term from both sides

Bret buys a dining table that costs $150 before tax. The sales tax is 8%. How much sales tax did he pay?

Answers

Bret paid $12 as sales tax.

What is a expression? What is a mathematical equation? What is Equation Modelling? What is denominator?

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem. In a fraction say (x/y), [y] is called denominator.

We have Bret buys a dining table that costs $150 before tax. The sales tax is 8%.

Assume that he paid $[x] as sales tax. Then, we can write -

[x] = 8% of 150

[x] = (8/100) x 150

[x] = 12

Therefore, Bret paid $12 as sales tax.
