Answer:

The measure of angle 1 is 115°

Step-by-step explanation:

we know that

If ∠1 and ​ ∠2 ​ are a linear pair

then

∠1 +∠2 =180°​ -----> supplementary angles

If ∠2 and ​ ∠3 ​ are vertical angles

then

∠2 =∠3

step 1

Find the value of y

we know that

∠2 =∠3

substitute values

(5+4y)°=(6y-25)°

6y-4y=(5+25)°

2y=(30)°

y=15°

step 2

Find the measure of angle 2

∠2=(5+4y)°

substitute the value of y

∠2=(5+4(15))°

∠2=65°

step 3

Find the measure of angle 1

we know that

∠1 +∠2 =180°

we have

∠2=65°

substitute

∠1 +65°=180°

∠1 =180°-65°=115°

The statement that best compares the graph of g(x) = -5x³ with the graph of f(x) = x³ is that the graph of g(x) is a reflection of the graph of f(x) across the x-axis and is vertically stretched by a factor of 5."

Option D is the correct answer.

We have,

Reflection across the x-axis:

The negative coefficient of -5 in g(x) reflects the graph across the x-axis compared to f(x).

This means that the points on the graph of g(x) will have the same

x-coordinates as the corresponding points on the graph of f(x) but will have opposite y-coordinates.

Vertical stretching by a factor of 5:

The absolute value of the coefficient (-5) in g(x) indicates that the graph is vertically stretched by a factor of 5 compared to f(x).

This means that for any given x-value, the corresponding y-value on the graph of g(x) will be five times larger (or smaller, depending on the sign) than the corresponding y-value on the graph of f(x).

Thus,

The graph of g(x) is a reflection of the graph of f(x) across the x-axis and is vertically stretched by a factor of 5."

Step-by-step explanation:

First find the volume of the cuboid, 15in x 9in x 7in = 945in^3

Then find the volume of the rectangular pyramid using the formula V=lwh/3, the total height is 17in so subtract the height of the cuboid from the total height, giving you 10in.

V=(15in)(9in)(10in)/3 = 450in^3

[tex]12x+7y\leq63[/tex]

[tex]y\geq0[/tex]

Step-by-step explanation:

If we let x be the amount of live bait and y be the amount of natural bait, Then we can come up with the following inequalities;

We are told that John would like to get at least 3 pounds of live bait. At least 3 means 3 or more. Since x represents the amount of live bait, we have;

[tex]x\geq3[/tex]

Moreover,we are informed that;

The store sells live bait for $12 a pound and natural bait for $7 a pound. x pounds of live bait would cost 12x while y pounds of natural bait would cost 7y. The total cost would thus be;

12x + 7y

but John only has a budget of $63. This implies that he can spend $63 at most, thus;

[tex]12x+7y\leq63[/tex]

Finally we can have our last inequality as;

[tex]y\geq0[/tex]

Check the picture below.

now, based on the provided information, we know the hexagon and triangle are regular polygons, equal sides and equal angles, we also know the angle in pink there of E and G are twins inside that irregular trapezoid, and you can see the exterior angles labeled there of 220° and 136°.

now, the trapezoid has twin angles at E and G, that means that the sides of DE and JG are equal and that also means that the other two angles inside that trapezoid are also twins, namely D and J.

if you notice the hexagon on the left-hand-side, a hexagon has interior angles of 120° and if we take a peek at the vertex at D, it has two angles then, one interior or 120° and an exterior of 136°, a full revolution will be 360°, so the remaining angle in green there must be 360° - 120° - 136°  = 104°, and her twin at vertex J is also 104°.

To find out how much flour is needed for three batches of rolls, you multiply 2 3/4 cups by three, resulting in 8 1/4 cups of flour.

Finding the Amount of Flour for Multiple Batches of Rolls

To calculate the amount of flour needed for three batches of rolls, we simply multiply the amount needed for one batch by three. The recipe states that you need 2 3/4 cups of flour for one batch. Thus, the mathematically formal way to find the amount for three batches is:

2 3/4 cups of flour × 3 = (2 × 3) + (3/4 × 3)

Now, solve the equation step by step:

Multiply the whole number: 2 × 3 = 6 cups of flour.

Multiply the fraction: 3/4 × 3 = 9/4, which can be simplified to 2 1/4 cups of flour by dividing 9 by 4.

Add the results from step 1 and step 2 together: 6 cups + 2 1/4 cups = 8 1/4 cups of flour.

Therefore, you would need 8 1/4 cups of flour to make three batches of rolls.

The average rate of change of f(x) in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

here [ a, b ] = [ - 7, - 1 ]

f(b) = f(- 1) = (- 1)² + 2(- 1) - 8 = 1 - 2 - 8 = - 9

f(a) = f(- 7) = (- 7)² + 2(- 7) - 8 = 49 - 14 - 8 = 27

Answer:

Total amount that Matthew's bank will receive is $10099.81.

Step-by-step explanation:

We need to find the amount Matthew's bank will receive after lending him $8,000 for four years at an interest rate of 6 percent, compounded annually.

The formula for compound interest is:

[tex]A=P(1+r)^n[/tex]

Where A = future value

P= Principal Amount

r = interest rate

and n= time

So in the question we are given:

P= $8000

r = 6% or 0.06

t = 4 (since 4 yeras compounded annually)

A= 8000*(1+0.06)^4

A= 8000*(1.06)^4

A= 10099.81

So, total amount that Matthew's bank will receive is $10099.81.

Answer:

Step-by-step explanation:

Car A: Started at 0 and ended at 300, thus, car A travels 300 miles.

It travels 6 hours, so car A speed is [tex]\frac{300}{6}=50[/tex] mph.

Car B: Started at 100 and ended at 300, thus, car B travels 300-100=200 miles.

It travels 5 hours, so car B speed is [tex]\frac{200}{5}=40[/tex] mph.

Since 50>40, car A traveled faster than car B.

The graph for the car A is steeper than the graph for the car B.

The cost of each bus for the school's field trip is approximately $192.20.

To calculate the cost of each bus, you first subtract the tip from the total expenses.

So, $1829.82 - $100 = $1729.82.

This is the total cost for the 9 buses without the tip.

Next, you divide this amount by the number of buses to find the cost per bus. $1729.82 / 9 = $192.20.

Therefore, each bus costs about $192.20.

Hello there! B. -2/5.

To solve for x, you want to get x alone and isolate all other terms.

2 = -6 – 20x  - Start by adding 6 to both sides of the equation.

2+6 = -6+6 – 20x ⇒ 8 = -20x

8 = -20x - Next, divide both sides of the equation by -20..

8/-20 = -20/-20x ⇒ -8/20 = x

Now, we have -8/20 as our value for x. The last step is to simplify. Since 8 and 20 are both divisible by 4, divide both sides of the fraction by 4.

x = -2/5. This is your final answer. I hope this helps and have a great day! ~ saturns

Answer:

400 to 500

Step-by-step explanation:

The increase in the price from $400 to $500 has got the larger change, that is the change of 25%.

The Latin term "per centum," which signifies "by the hundredth," was the source of the English word "percentage." Segments with a denominator of 100 are considered percentages. In other terms, it is a relationship where the worth of the entire is always considered to be 100.

As per the data provided in the question,

Percentage change from $400 to $500

% change = (500 - 400)/400 × 100

% change = 25%

Percentage change from $500 to $600,

% change = (600 - 500)/500 × 100

% change = 20%

Therefore, $400 to $500 has the largest change.

Final answer:

The combined probability of scoring less than 200 or greater than 800 on a normally distributed college-entrance exam with mean 500 and standard deviation 100 is approximately 0.3%.

Explanation:

The probability that a randomly chosen exam score is less than 200 or greater than 800 in a normally distributed college-entrance exam can be found by using the properties of the normal distribution. Since the mean score is 500 and the standard deviation is 100, scores below 200 are three standard deviations below the mean, and scores above 800 are three standard deviations above the mean. Given the symmetry and the empirical rule of normal distribution, approximately 99.7% of values lie within three standard deviations from the mean, leaving roughly 0.3% of the values outside this range. Therefore, since both tails (below 200 and above 800) are considered, we need to split this percentage, which gives us approximately 0.15% (or 0.0015 in probability terms) for each tail. Thus, the combined probability of scoring less than 200 or greater than 800 is approximately 0.3% (or 0.003 in probability terms).
