Lev has 9 tens . Jim has 1 ten. They put all their tens together. Dawn puts 9 ones with the tens. What number did they make?

Answers

Answer 1
The answer would be 109. 9 tens is 90, and 1 ten is 10, 90+10=100 plus the 9 ones that Dawn put, 109
Answer 2

Lev and Jim have a total of 100 in tens, and with Dawn's 9 ones added, they make the number 109.

Lev has 9 tens which is equal to 90 (because 9 times 10 equals 90). Jim has 1 ten which is equal to 10. When they put all their tens together, we add 90 and 10 to get 100. Dawn then adds 9 ones to the tens. To find the final number, we add Dawn's 9 ones to the previously combined tens, which is adding 9 to 100, resulting in 109. Therefore, by pooling together their tens and ones, they made the number 109.

Danika is making necklaces.she has 512 silver beads and 278 blue.About how many more silver than beads does Danika have?

Answers

Daniela has 234 more silver beads than blue beads

Answer:

234 more silver beads.

Step-by-step explanation:

We have been given that Danika is making necklaces. She has 512 silver beads and 278 blue.

To find the number of silver beads is how much more than blue beads, we will subtract number of blue beads from silver beads.

[tex]\text{Number of more silver beads}=512-278[/tex]

[tex]\text{Number of more silver beads}=234[/tex]

Therefore, Danika has 234 more silver beads than blue beds.

what is the complete factorization of the polynomial below. x^3-3x^2+x-3

Answers

Answer:

(x-3)(x+i)(x-i)

Step-by-step explanation:

[tex]x^3-3x^2+x-3[/tex]

We apply grouping method

We group first two terms and last two terms

[tex](x^3-3x^2)+(x-3)[/tex]

Take out GCF x^2 from first group. Also take out 1 from second group

[tex]x^2(x-3)+1(x-3)[/tex]

[tex](x-3) (x^2+1)[/tex]

Now we factor x^2 + 1

We  use difference of square formula

a^2 - b^2 = (a+b)(a-b)

x^1 + 1 can be written as [tex]x^2 - (-1)[/tex], the value of -1 is i^2

[tex]x^2 +1 = x^2 -(-1) = x^2 - i^2[/tex]

x^2 - i^2 = (x+i)(x-i)

The complete factorization of the polynomial x^3 - 3x^2 + x - 3 is (x - 3)(x^2 + 1). The process involves grouping and factoring out common terms.

The question asks for the complete factorization of the polynomial x^3 - 3x^2 + x - 3. To factor this polynomial, we are looking for factors of the lowest possible order that will multiply together to give us the original polynomial. Let's first look for a common factor in all the terms. In this case, there isn't a common factor except for 1, so we move on to finding factors through other means such as grouping.

We can attempt to group terms to facilitate the factoring process:

First, consider the polynomial in two parts (x^3 - 3x^2) and (x - 3).Within the first group (x^3 - 3x^2), we can factor out an x^2, which gives us x^2(x - 3).The second group is already in the form (x - 3), mirroring the (x - 3) factor we found in the first group.We then combine these to get the full expression x^2(x - 3) + (x - 3).Next, we can factor out the common (x - 3) term from both groups, obtaining (x - 3)(x^2 + 1).

The polynomial x^3 - 3x^2 + x - 3 can now be expressed as the product of (x - 3) and (x^2 + 1). This represents the polynomial in its factored form using real coefficients.

Rodrigo is starting his own part time business. He plans to earn $25 per hour. He has the following expenses each month, $750 for overhead, $110 for phone and fax and $75 for materials. a. Write an equality that describes the number of hours h he must work to earn a profit of $625. b. How many hours should he have worked to earn a profit of at least $625?

Answers

revenue - expenses = profit
25h - (750 + 110 + 75) > = 625 
25h - 935 > = 625 <== ur inequality (simplified)
25h > = 625 + 935
25h > = 1560
h > = 1560/25
h > = 62.4 hrs <==



The equality that describes the number of hours h he must work to earn a profit of $625 is h = 62.4 hours and The inequality that describes the number of hours h he must work to earn a profit of atleast $625 is [tex]\rm h \geq 62.4\;hours[/tex] and this can be determine by using arithmetic operations.

Given :

a). Let the total number of hours be 'h'. The equality that describes the number of hours Rodrigo needs to work to earn a profit of $625 is given by:

25h - (750 + 110 + 75) = 625

so 1/5 of 1/7 goes to the American Cancer Society...." of " means multiply
1/5 * 1/7 = 1/35 <== 1/35 goes to the AMC

Final answer:

The American Cancer Society receives 1/35 of the total estate after it has been divided among relatives and other beneficiaries. This is determined by multiplying the fraction of the estate remaining (1/7) by the fraction of that remaining estate going to the Cancer Society (1/5).

Explanation:

The question states that six-sevenths, or 6/7, of the estate has been divided among relatives, which leaves one-seventh, or 1/7, of the estate remaining. It is this remaining fraction that is further divided, with one fifth, or 1/5, going to the American Cancer Society. To determine the fraction of the total estate that this represents, we multiply these two fractions together: [tex]1/7 * 1/5 = 1/35.[/tex] Therefore, the American Cancer Society receives one-thirty-fifth of the total estate.

$2913.93
b.
$2899.93
d.
$794.40

Answers

1986*1.04^(23) = 4894.93


4894.93-1986 = 2908.93


Answer is A


Answer:

a.  $2908.93

Step-by-step explanation:

We have been given that Stan’s savings account has a balance of $1986. The amount of interest be at 4% compounded annually.

To find the final amount after 23 years we will use compound interest formula.

[tex]A=P(1+\frac{r}{n})^{nT}[/tex], where,

A = Final amount,

P= Principal amount,

r = Annual interest rate in decimal form,

n = Number of times interest in compounded per year,

t = Time in years.

Let us convert our given rate in decimal form.

[tex]4\%=\frac{4}{100}=0.04[/tex]

Upon substituting our given values in above formula we will get,

[tex]A=\$1986(1+\frac{0.04}{1})^{1*23}[/tex]

[tex]A=\$1986(1+0.04)^{23}[/tex]

[tex]A=\$1986(1.04)^{23}[/tex]

[tex]A=\$1986*2.4647155431651442[/tex]

[tex]A=\$4894.9250687259763812[/tex]

To find the amount of interest we will subtract principal amount from final amount.

[tex]\text{Amount of interest}=\$4894.9250687259763812-\$1986[/tex]

[tex]\text{Amount of interest}=\$2908.925068725976\approx 2908.93[/tex]

Therefore, the amount of interest after 23 years will be $2908.93 and option a is the correct choice.

Your car is skidding to a stop from a high speed. you may want to review ( pages 112 - 114) . part a identify all forces acting on the object.

Answers

There are four (4) that can be identify in all forces that acting on the object. Normal force, \vec{n} is a component that is perpendicular to the surface of contact. Air resistance, \vec{D} is a type of friction and it is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. Kinetic friction force, \vec{f}_k is μk times the normal force on an object and it is expressed in units of Newtons. Weight, \vec{w} is a force caused by gravity and it is measured in Newtons.

The forces acting on a car which is skidding to a stop are its weight due to gravity, a normal force coming from the ground, and the friction force due to the relative movement between the tires and the ground. Theoretically, we should also consider the friction force due to air viscosity, however practically we can neglect this force since it's contribution is very small in comparsion to the others (specially at low speeds).

Further explanation

By making the free body diagram of the car, we can observe 3 things:

The car has a certain mass, therefor due to the effect of gravity, it will have certain weight pointing towards the ground. It is important to remember that the weight always points downwards, even if the car would be on an inclined plane.Even though weight pulls the car down, the floor excerts a force over the car upward which keeps it in place. This is called the normal force and it is always perpendicular to the ground.Due to the roughness of the tires and the concrete, there will be a friction force do the relative movement between them. This friction force always goes in the opposite direction in which the car is moving (so if the car is heading to the right, the friction force aims towards the left, thus slowing it down).

As a reference you can check the attached image, which shows how the forces would be in case the car would brake on a horizontal street. In case the car would be slowing on a floor which is not horizontal, like on a hill, the forces would have different directions.
