8/10 of 3/9 is what?

From IXL

The value of the lesser integer is -9. The solution has been obtained by using algebra.

What is algebra?

In the area of mathematics known as algebra, abstract symbols rather than actual numbers are used to perform operations or manipulations.

Let the integer be 'x'.

We are given that when an integer is subtracted from 2 times the next consecutive integer, the difference is -7.

So, from this we can form the equation as

⇒2(x+1) - x = -7

⇒2x + 2 - x = -7

⇒x = -7 - 2

⇒x = -9

Hence, the value of the lesser integer is -9.

The length of DE is  25. So correct option is (4).

In geometry, the term "parallel" refers to two lines that are equidistant from each other over their entire length and will never intersect, no matter how far they are extended. In other words, two parallel lines are parallel if they lie in the same plane and maintain the same distance between them at all times.

Since AB is parallel to DE and BD is perpendicular to both AB and DE, by alternate interior angles, we have:

angle BDA = angle DEC

Since BD is 7 and BC is 15, we have:

triangle BCD is a 7-15-17 right triangle (the Pythagorean theorem)

So, angle BDA = angle DEC = 90 - arctan(7/15) = arctan(15/7).

Also, since AB is parallel to DE, and BD is perpendicular to both AB and DE, we have:

angle ABD = angle CDE

So, by the vertical angles theorem, we have:

angle ABD = angle CDE = 90 degrees - arctan(15/7) = arctan(7/15)

Then, by the Pythagorean theorem, the length of DE can be found as:

[tex](DE)^{2}[/tex] = [tex](AB)^{2}[/tex] + [tex](BD)^{2}[/tex] = [tex]21^{2}[/tex] + [tex]7^{2}[/tex] = 441 + 49 = 490

So, DE = [tex]\sqrt{490}[/tex] = 2[tex]\sqrt{122}[/tex] = 2 * 11 = 22

Therefore, the length of DE is (4) 25.

To calculate the amount of money that needs to be set aside today to purchase a new piece of equipment in 3 years, we need to find the future value of the equipment and calculate the present value of that future amount.

First, let's find the future value of the equipment:

The cost of the equipment is expected to increase by 3% per year, so after 3 years the cost will be:

$75,000 * (1 + 0.03)^3 = $78,225

Next, let's find the present value of that future amount:

The money is expected to earn 9% interest compounded annually, so to find the present value, we need to discount the future amount by the interest rate. We can use the formula:

PV = FV / (1 + r)^t

where PV is the present value, FV is the future value, r is the interest rate, and t is the number of years.

Plugging in the values, we get:

PV = $78,225 / (1 + 0.09)^3 = $73,232.57

So, to purchase the equipment in 3 years, we need to set aside $73,232.57 today.

Remember this definition:

A rhombus is a special case of a parallelogram. In a rhombus, opposite sides are parallel and the opposite angles are equal. Moreover, all the sides of a rhombus are equal in length, and the diagonals bisect each other at right angles. The rhombus is also called a diamond or rhombus diamond.

so if you know only 1 angle, you'll know all of them

because  z is opposite to the given angle 69 so z=69

the other 2 angles are the same = 180 -69 =111

The exponential equation is P = 7000 * (1 + 0.08)ᵗ  and the nearest whole number.

What is the exponential equation?

In combinatorial mathematics, the exponential formula (called the polymer expansion in physics) states that the exponential generating function for structures on finite sets is the exponential of the exponential generating function for connected structures.

a. To write the exponential equation, let t be the number of years and let P be the amount of money in the account after t years. The exponential equation can be written as:

P = 7000 * (1 + 0.08)ᵗ

b. To solve for t, we need to find the number of years it takes for P to reach $30,100. We can set up an equation and solve for t:

30,100 = 7000 * (1 + 0.08)ᵗ

Dividing both sides by 7000:

30,100 / 7000 = (1 + 0.08)ᵗ

Taking the natural logarithm of both sides:

ln (30,100 / 7000) = t * ln (1 + 0.08)

Solving for t:

t = ln (30,100 / 7000) / ln (1 + 0.08)

Using a calculator, we get:

t = 21.1397

Rounding up to the nearest whole number, it will take Fred 22 years to have $30,100 for a new car.

Hence, the exponential equation is P = 7000 * (1 + 0.08)ᵗ  and the nearest whole number.

The formula for the function obtained when the graph is shifted is f(x)=(x+7)^3+3.

Suppose the considered function whose graph is to be made is function f(x). The values of 'x' (also called input variable, or independent variable) are usually plotted on horizontal axis, and the output values f(x) are plotted on the vertical axis.

They are together plotted on the point

(x,y) = (x, f(x))

This is why we usually write the functions as:

y = f(x)

Given;

f(x)=x^3 is shifted up 3 unit and to the left 7 units.

Now,

To shift upwards, we will add outside of the argument

To shift to the left, we will add inside of the argument

An angle is a figure in Euclidean geometry created by two rays, called the sides of the angle, that share a common termination, called the vertex of the angle. Angles created by two rays are located in the plane containing the rays. Angles are also generated when two planes intersect. These are known as dihedral angles. An angle is formed by joining two rays (half-lines) that have a shared terminal. The latter is referred to as the angle's vertex, while the rays are referred to as the angle's sides, legs, and arms.

4x² + 4x + 9 = 0 , has no real solutions

Step-by-step explanation:

given a quadratic equation in standard form

ax² + bx + c = 0 ( a ≠ 0 )

then the nature of the solutions can be determined using the discriminant.

Δ = b² - 4ac

• if b² - 4ac > 0 , then real solutions

• if b² - 4ac = 0 , then real and equal solutions

• if b² - 4ac < 0 , then no real solutions

4x² + 4x + 9 = 0 ← in standard form

with a = 4, b = 4 , c = 9

b² - 4ac

= 4² - (4 × 4 × 9)

= 16 - 144

= - 128 ← no real solutions

------------------------------------------

- 4x² + 56x - 196 = 0 ← in standard form

with a = - 4 , b = 56 , c = - 196

b² - 4ac

= 56² - (4 × - 4 × - 196)

= 3136 - 3136

= 0 ← has real solutions

-------------------------------------------

- 5x² - 10x + 10 = 0 ← in standard form

with a = - 5 , b = - 10 , c = 10

b² - 4ac

= (- 10)² - (4 × - 5 × 10)

= 100 - (- 200)

= 100 + 200

The rule for the function is P(t) = 170 + 680t

Let's call Julia's final position after t hours as P.

If she drove at a constant speed v (in miles per hour), then the distance traveled can be given as:

P - P0 = vt

Given that she was 170 miles east from Denver after driving for a quarter of an hour (0.25 hours), we can write the first equation:

170 = v * 0.25

v = 680

This means that her speed was 680 miles per hour.

Using this speed, we can write the second equation:

P = 680 * t

100 = 680 * t

t = 100 / 680 = 0.147

Combining the two equations, we can find the function that gives Julia's position east from Denver after t hours as:

P(t) = P0 + v * t ----- P0 = 170 i.e. her initial position

P(t) = 170 + 680 * t

So, the rule for the function P(t) is:

P(t) = 170 + 680t

P^-1(16) is the inverse of the function P(t) at the value 16.

In other words, it gives us the time t after which Julia is 16 miles east from Denver.

To find its value, we can use the equation of the function P(t):

P(t) = 170 + 680 * t

16 = 170 + 680 * t

-154 = 680 * t

t = -154 / 680

Time cannot be negative.

So, it does not exist

P^-1(-141) is the inverse of the function P(t) at the value -141.

In other words, it gives us the time t after which Julia is 16 miles east from Denver.

So, we have

-141 = 170 + 680 * t

-311 = 680 * t

t = -311 / 680

Time cannot be negative.

So, it does not exist

We simply make t the subject in P(t)

So, we have

P^-1(t) = (t - 170) / 680

Step-by-step explanation:

9+7+7+7+7+7+7

(or 9+7^6)

Answer:

Step-by-step explanation:

To find the number of hours David has to work at each job, we can set up an equation. Let's say David works x hours at the first job and y hours at the second job. Then, we have:

14x + 11y = 1000

Next, we need to find the possible combinations of x and y that satisfy this equation. To do this, we can use trial and error, or use the substitution method. Let's use the latter method. Solve for x in terms of y:

14x = 1000 - 11y

x = (1000 - 11y) / 14

Now, we can substitute this expression for x into the original equation to get a new equation in terms of y:

11y = 1000 - 14x

y = (1000 - 14x) / 11

We can use this equation to find possible values of y. For example, if x = 40 hours, then y = (1000 - 14 * 40) / 11 = (1000 - 560) / 11 = (440) / 11 = 40. So, David could work 40 hours at the first job and 40 hours at the second job to earn $1000.

We can repeat this process for other values of x to find more combinations. Some possible combinations of the numbers of hours David could work at each job to earn $1000 are:

40 hours at the first job and 40 hours at the second job

45 hours at the first job and 35 hours at the second job

50 hours at the first job and 30 hours at the second job

55 hours at the first job and 25 hours at the second job

60 hours at the first job and 20 hours at the second job, etc.
