The value of d in the image that shows the two parallel lines that are crossed by the transversal is determined as: 125°.

In geometry, a transversal is a line that intersects two or more other lines at distinct points. When a transversal intersects a pair of parallel lines, it creates various angles and relationships between those angles.

The image attached below shows the two parallel lines which are crossed by the transversal, where angle d and 125° are vertical angles.

Since they are vertical angles, they will be equal or congruent to each other. Therefore, the value of d = 125°

What is Proportion?

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

Given data ,

Amount of fertilizer required to cover 25 square foot ground = 18 pound

Amount of fertilizer required to cover 1 square foot ground = Amount of fertilizer required / total square foot ground

Amount of fertilizer required to cover 1 square foot ground = 18 / 25

Therefore , Amount of fertilizer = 0.72 pound

Hence , the amount of fertilizer required to cover 1 square foot of ground is 0.72

Step-by-step explanation:

if to re-write the given condition, then

\(\frac{3}{0.25} =\frac{18}{1.5} =\frac{30}{2.5} =\frac{36}{3} ;\)

it is clear, the required constant is 12 (12 per hour).

The polynomial -8m²n - 7m²n can be factored using the common factor -m²n. The complete factored form of the polynomial is (-m²n) (8 + 7a).

To find the complete factored form of the polynomial -8m²n - 7m²n, we can factor out common terms from both the terms. The common factor in the terms -8m²n and -7m²n is -m²n. We can write the polynomial as:

-8m²n - 7m²n = (-m²n) (8 + 7a)

Therefore, the complete factored form of the polynomial -8m²n - 7m²n is (-m²n) (8 + 7a). This expression represents the original polynomial in a multiplied form. We can expand this expression using distributive law to verify that it is equivalent to the original polynomial.

Answer:

to the second part

18.7 inches

Answer:

a). x = 11

b). m∠DMC = 39°

c). m∠MAD = 66°

d). m∠ADM = 36°

e). m∠ADC = 18°

Step-by-step explanation:

a). In the figure attached,

m∠AMC = 3x + 6

and m∠DMC = 6x - 49

Since "in-center" of a triangle is a points where the bisectors of internal angles meet.

Therefore, MC is the angle bisector of angle AMD.

and m∠AMC ≅ m∠DMC

3x + 6 = 8x - 49

8x - 3x = 49 + 6

5x = 55

x = 11

b). m∠DMC = 8x - 49

                   = (8 × 11) - 49

                   = 88 - 49

                   = 39°

c). m∠MAD = 2(m∠DAC)

                   = 2(30)°

                   = 60°

d). Since, m∠AMD + m∠ADM + m∠MAD = 180°

    2(39)° + m∠ADM + 66° = 180°

    78° + m∠ADM + 66° = 180°

    m∠ADM = 180° - 144°

                   = 36°

e). m∠ADC = \(\frac{1}{2}(m\angle ADM)\)

                   = \(\frac{1}{2}(36)\)

                   = 18°

Answer:

Step-by-step explanation:

We can use the law of total probability to calculate the probability that the Hope River will overflow its banks this season:

P(overflow) = P(overflow | heavy rain) x P(heavy rain) + P(overflow | no heavy rain) x P(no heavy rain)

From the problem statement, we are given:

P(overflow | heavy rain) = 0.65 (the probability of overflow given heavy rain)

P(overflow | no heavy rain) = 0.15 (the probability of overflow given no heavy rain)

P(heavy rain) = 0.75 (the probability of heavy rain)

We can find P(no heavy rain) as:

P(no heavy rain) = 1 - P(heavy rain) = 1 - 0.75 = 0.25

Substituting these values, we get:

P(overflow) = 0.65 x 0.75 + 0.15 x 0.25

= 0.4875 + 0.0375

= 0.525

Therefore, the probability that the Hope River will overflow its banks this season is 0.525, or 52.5%.

Answer:

15/13

Step-by-step explanation:

1 1/12=13/12

5/4 divided by 13/12= 5/4*12/13

which cross simplifies to

5/1*3/13

which multiplies to 15/13

\(\frac{15}{13}\) will be the improper fraction.

  We have to find the improper fraction when \(\frac{5}{4}\) is divided by \(1\frac{1}{12}\).

Convert the mixed number \(1\frac{1}{12}\) to a improper fraction first.

\(1\frac{1}{12}=\frac{12(1)+1}{12}\)

      \(=\frac{13}{12}\)

Now divide \(\frac{5}{4}\) by \(\frac{13}{12}\),

\(\frac{\frac{5}{4}}{\frac{13}{12}}=\frac{5}{4}\times \frac{12}{13}\)

    \(=\frac{15}{13}\)

  Therefore, improper fraction \(\frac{15}{13}\) will be the answer.

It will take approximately 6.1 minutes to fill the pool to a depth of 20 cm at the given fill rate.

Find the radius of the pool:

Since the diameter is 115 cm, the radius (r) will be half of that:

Radius (r) = Diameter / 2

r = 115 cm / 2

r = 57.5 cm

Calculate the volume of the pool when filled to a depth of 20 cm:

Since the pool is round and assuming it has a cylindrical shape, we can use the formula for the volume of a cylinder:

Volume = π × r² × h

where π (pi) is approximately 3.14159, r is the radius, and h is the height (or depth, in this case).

Volume = 3.14159 × (57.5 cm)² × 20 cm

Evaluate the volume:

Volume ≈ 3.14159 × 3306.25 cm² × 20 cm

Volume ≈ 3.14159 × 66125 cm³

Volume ≈ 207354.2 cm³

Calculate the time it takes to fill the pool to a depth of 20 cm:

We are given that the hose fills the pool at a rate of 34,000 cm³ per minute. To find out how long it will take to fill the pool, we can use the following formula:

Time = Volume / Fill Rate

Time ≈ 207354.2 cm³ / 34,000 cm³/min

Time ≈ 6.1 minutes

It will take approximately 6.1 minutes to fill the pool to a depth of 20 cm at the given fill rate.

There can be multiple outputs (monthly charges) for a given input (number of credit cards), violating the definition of a function. hence, Situation 3 does not represent a function.

Situation 3: the total amount of money charged monthly on credit cards to the number of credit cards owned does not represent a function.

In a function, each input (or x-value) should have a unique output (or y-value). However, in this situation, the total amount of money charged monthly on credit cards depends on the number of credit cards owned. It is possible to have different credit card numbers but still have the same total amount of money charged monthly.

For example, two people could own different numbers of credit cards but have the same monthly charges.

As a result, the definition of a function can be violated by having many outputs (monthly charges) for a single input (number of credit cards).

to solve this question, we can find the percentage she gives to charity o every dollar she earns

if she earns $100, she gives $10 to charity. let's find the percentage on this.

from the calculation, she gives 10% of are earnings to charity.

now we can find 10% of $500 to solve this question.

from the calculations above, she gives out $50 on charity weekly from her $500 income.

using simultaneous equation:

2x + 3y = 190

3x + y = 180  * 3

Then:

2x + 3y = 190

9x + 3y = 540

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

-7x = -350

x = 50

Insert this in equation 1 to find value of y:

2x + 3y = 190

2(50) + 3y = 190

3y = 190 - 100

3y = 90

y = 30

expanding the following:

→ (x + 2)³

\(\sf apply \ cubic \ formula : \bold{\left(a+b\right)^3=a^3+3a^2b+3ab^2+b^3}\)

\(\rightarrow \sf x^3+3x^2\cdot \:2+3x\cdot \:2^2+2^3\)

\(\rightarrow \sf x^3+6x^2+12x+8\)

Justify for x = 5

\(\rightarrow \sf (5)^3+6(5)^2+12(5)+8\)

\(\rightarrow \sf 125+150+60+8\)

\(\rightarrow \sf 343\)

Answer:

Step-by-step explanation for (a):

First use system of equations. Isolate a variable and substitute.

2x + 3y = 190

3x + y = 180

Isolate

subtract 3x from both sides of the second equation

y = 180 - 3x

since 180 - 3x = y, you can substitute this into the first equation for y

Substitute

2x + 3y = 190

2x + 3(180 - 3x) = 190

Distribute the 3

2x + (540 - 9x) = 190

Solve for x

subtract 540 from both sides

2x - 9x = -350

simplify

-7x = -350

divide each side by -7

x = 50

But you still need to solve for y, so substitute the x back into the first equation.(But really you could use either equation)

2(50) + 3y = 190

subtract 100 (2 * 50) from both sides

3y = 90

y = 30

Check your work by resubstituting.

3(50) + 30 = 180.

(b) This one is weird.

(Remember, it is NOT (x^3 + 8), you don't "distribute" the exponent)

It then simplifies to x^3 + 6x^2 + 12x + 8, and x = 5 is NOT an answer here. Maybe there is something more that you might not have screenshotted?

*edit its not asking to prove x is a solution(which i thought lolllll) its asking to plug x = 5 into the equation*
