Answer 1

Answer:

x = -1, x = 3  (B)

Step-by-step explanation:

25ˣ=5ˣ²⁻³

Can be simplified to:

5²ˣ=5ˣ²⁻³

2x=x²-3

x²-2x-3=0

(x-3)(x+1)

x = -1, x = 3

Plz mark my answer as brainiest

Answer 2

Answer:

B  x=-1   x=3

Step-by-step explanation:

25^x = 5 ^ (x^2 -3)

Replace 25 by 5^2

5^2^x = 5 ^ (x^2 -3)

We know that a^b^c = =a^(b*c)

5^(2x) = 5 ^ (x^2 -3)

The bases are the same so the exponents must be the same

2x = x^2 -3

Subtract 2x from each side

2x-2x = x^2 -3 -2x

0 = x^2 -2x-3

Factor

0 =(x-3) (x+1)

Using the zero product property

x-3 =0       x+1 =0

x=3             x=-1

Harper knows he is 50 yards from his school. The map on his phone shows that the school is 3/4 inch from his current location. How far is Harper from home, if the map shows the distance as 3 inches?

Answers

Answer:200

Step-by-step explanation:

3÷3/4=4

4x50=200

34 inches represents 50 yards.

So, 1 inches could be represented by 50/34 = 25/17 yards.

Multiply 1 inches value of yards by 3 to find the length of 3 inches in yards.

25/17 = 75/17 = 4 7/17 yards.

Let t = the tens digit and u = the units digit.

t + u = 8

10u + t = 10t + u + 54

10(8 - t) + t = 10t + 8 - t + 54

A cone with a height of 50 meters has a volume of 5400pie what is the radius of the cone

Answers

Given:

Height of a cone = 50 m

Volume of cone = 5400π

To find:

The radius of the cone

Solution:

Volume of cone:

[tex]$V=\frac{1}{3}\pi r^2h[/tex]

[tex]$\frac{1}{3}\pi r^2h=5400\pi[/tex]

Cancel common factor π on both sides.

[tex]$\frac{1}{3} r^2h=5400[/tex]

Substitute h = 50.

[tex]$\frac{1}{3}\times r^2\times 50=5400[/tex]

Multiply by 3 on both sides.

[tex]$3 \times \frac{1}{3}\times r^2\times 50=5400\times 3[/tex]

[tex]$ r^2\times 50=16200[/tex]

Divide by 50 on both sides, we get

[tex]r^2=324[/tex]

Taking square root on both sides, we get

Which order pair is a solution of this equation. 5x+y=-25

Answers

Answer:

(-5,0) or (0,-25) is another solution

Step-by-step explanation:

Do you have a list of choices? If not, you could choose random choices for x and y to determine if they are solutions. Start by letting y = 0. We see that x = -5, so (-5, 0) is a solution to this equation. In fact, it represents the x-intercept of this line. Now, let x = 0. We now see that y = -25, so (0, -25) is another solution to the equation of this line. This coordinate pair is the y-intercept of the line. Try using other values of x and y to see if you can come up with other solutions to this equation.

It took Skylar a full minute to recall the chain of events that had brought her here,
deep into outer space. She had awoken from her deep, dreamless sleep only a few

surroundings, recognizing the instruments and equipment around her. Everything
had gone according to plan, and she had been asleep throughout the entire three-
year journey. Now, she had a crucial mission to carry out, one that would influence
the very course of life back on Earth.

Step-by-step explanation:

i think the answer is 3 because of the quote "now, she had a crucial mission to carry out, one that would influence  the very course of life back on Earth."

hope this helps!

Final answer:

The plot will likely focus on Skylar's crucial mission in outer space, portraying her as an archetypal heroine, with the story revealing the destabilizing condition that led her to this moment.

Explanation:

Based on the excerpt, it's most likely that the plot will involve Skylar embarking on a crucial mission that affects life on Earth, suggesting that the narrative will focus on her as an archetypal heroine. Given that she's just awakened from a three-year journey in deep space, we can infer a narrative structure that will emphasize her actions and decisions in outer space rather than detailing her entire life history or returning home immediately. The story seems poised to dive into the destabilizing condition that brought Skylar into space, likely escalating towards a central conflict related to her mission, while building empathy for her character as she navigates challenges in a foreign environment.

what is a/8 - 7(3) = 4a - 78(b)

solve for b pls

Answers

Answer:

31a/624 +7/26 = b

Step-by-step explanation:

a/8 - 7(3) = 4a - 78(b)

Multiply

a/8 - 21 =4a -78b

Multiply each side by 8 to get rid of the fractions

8(a/8 - 21) =8(4a -78b)

a - 168 = 32a -624b

Subtract 32a from each side

a -32a -168 = 32a -32a -624b

-31a -168 = -624b

Divide each side by -624

(-31a -168)/-624 = -624b/-624

(31a+168)/624 = b

31a/624 +7/26 = b

Answer:

b = (31a + 168)/624

Step-by-step explanation:

a/8 - 7(3) = 4a - 78(b)

78b = 4a - a/8 + 21

78b = (32-1)a/8 + 21

78b = (31a + 21(8))/8

78b = (31a + 168)/8

b = (31a + 168)/8 × 1/78

b = (31a + 168)/624

kalvin's mother tells him that the chance of a coin showing heads when he tosses it is 1/2. does this mean that every time he tosses a coin twice, he will get one head and one tail.

Answers

No it is not necessary that Kelvin will get one head and one tail every time

Explanation:

Probability in math is equal to favorable outcomes/total outcomes

The coin has two sides a head and a tail. When we flip a coin we have 50-50 possibility of getting a head and a tail. It means with every toss we have 1/2 possibility of getting head as well as tail.

But this does not mean that when we toss a coin twice we will get one head at one toss and one tail at another toss.

There is a possibility of getting both heads as well as both the tails.

zack is standing at the top of a lookout tower and spotsa a water fountain below. if the lookout tower is 75 feet tall and the angle of depression is 28 what is the horizontal distance between zack and the water fountain

Answers

The horizontal distance between Zack and the water fountain is approximately 141.1 feet.

To find the horizontal distance between Zack and the water fountain, we can use trigonometry.

The tangent function relates the angle of depression (\(\theta\)) to the opposite side (height of the tower, \(h\)), and the adjacent side (horizontal distance, \(d\)):

[tex]\[ \tan(\theta) = \frac{h}{d} \][/tex]

Given:

Height of the tower = 75 feet

Angle of depression  = 28°

We rearrange the formula to solve for \(d\):

[tex]\[ d = \frac{h}{\tan(\theta)} \]\[ d = \frac{75}{\tan(28°)} \]Calculating \(\tan(28°)\), and then the distance \(d\):\[ \tan(28°) = 0.531 \]\[ d = \frac{75}{0.531} \]\[ d = 141.1 \][/tex]

So, the horizontal distance between Zack and the water fountain is approximately 141.1 feet.

The area of the pyramid's base is 36 square inches.

Area of base = s*s = 6*6 = 36

The pyramid has 4 lateral faces.

Count how many non-bases there are.

The surface area of each lateral face is 18 square inches.

Area of lateral face = 1/2 b*h = 1/2 9*6 = 18

The area of the pyramid’s base is 36 in² and the surface area of each lateral face is 108 in². Then the total surface area is 144 in².

What is Geometry?

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

The area of the pyramid’s base will be

Base area = 6 × 6

Base area = 36 in²

The area of the pyramid’s base is 36 in².

The pyramid has lateral faces that will be

Lateral face = 0.5 × 6 × 9

Lateral face = 27 in²

Then the surface area of each lateral face will be

Surface area = 4 × 27

Surface area = 108 in²

The surface area of each lateral face is 108 in²

Then the total surface area is 144 in².

Which strategy would you choose to expand (x+11)(2x+3) and write an equivalent expression

Answers

Answer:

Step-by-step explanation:

Given the expression (x+11)(2x+3)

We want to expand it and write equivalent expression

Generally if we want to expand an expression we will take one of the expression in one bracket and multiply with the other bracket and then take the other expression and multiply it with the other

E.g, (a+b) × (c + d)

Then, we take a × (c+d) and also b × (c+d)

We can do it the other way round too and it will give the same results.

So, applying this to the given expression

(x+11)(2x+3)

x(2x+3) + 11(2x+3)

2x² + 3x + 22x + 33

2x² + 25x + 33

Then, the equivalent expression is 2x² + 25x + 33

(x + 11)(2x + 3) = 2x² + 25x + 33

There are 4 teams in a soccer tournament. Each team plays each of the other teams exactly once. In each match, the winner receives 3 points and the loser receives 0 points. In the case of a tie, both teams receive 1 point. After all the matches have been played, which of the following total number of points is it impossible for any team to have received?

Answers

Answer:

8 points

Step-by-step explanation:

Given that there are 4 teams and Each team plays each of the other teams exactly once, then each team plays 3 matches. The possible points after 3 matches are:

0: 3 lost

1: 2 lost, 1 tied

2: 2 tied, 1 lost

3: 3 tied

4: 1 won, 1 lost, 1 tied

5: 1 won, 2 tied

6: 2 won, 1 lost

7: 2 won, 1 tied

9: 3 won

The answer is 8 points.

Since there are 4 teams in a soccer tournament, and each team plays each of the other teams exactly once, and in each match, the winner receives 3 points and the loser receives 0 points, while in the case of a tie, both teams receive 1 point, to determine, after all the matches have been played, which total number of points is it impossible for any team to have received, the following mathematical logical reasoning must be performed:

0 points = 3 losses = possible 1 point = 1 draw, 2 losses = possible 2 points = 2 draws, 1 loss = possible 3 points = 1 win, 2 losses or 3 draws = possible 4 points = 1 win, 1 draw, 1 loss = possible 5 points = 1 win, 2 draws = possible 6 points = 2 wins, 1 loss = possible 7 points = 2 wins, 1 draw = possible 8 points = impossible, it takes at least 4 matches to achieve that combination 9 points = 3 wins = possible

Erik buys 2.5 pounds of cashews.If each pound of cashews cost $7.50, how much will he pay for the cashews

Answers

Erik will pay $18.75 for the cashews.

Erik will pay $18.75 for 2.5 pounds of cashews because the price is $7.50 per pound, and the cost is calculated by multiplying the price per pound by the number of pounds.

To calculate how much Erik will pay for 2.5 pounds of cashews at a rate of $7.50 per pound, you simply multiply the number of pounds of cashews by the price per pound.

The formula to determine the cost is: Total Cost = Price per Unit x Quantity.For Erik's purchase, this would be: Total Cost = $7.50 x 2.5.

Let's do the calculation:

First, multiply 7.50 by 2.5, which equals 18.75.This means Erik will pay $18.75 for the cashews.
