Answer: 7.5×10^-4

Step-by-step explanation:

0.00075

Scientific notation means standard form

There are 3 zeros in front of the 7

So take the decimal to the back of 7

You have

7.5

Since you are counting backward, it will be negative

So we have

7.5×10^-4

Answer:

[tex]7.5 * 10^{-4}[/tex]

Step-by-step explanation:

Scientific notation is basically taking a decimal number and writing it as the product of a number between 1 and 10 (including 1 but excluding 10) and a power of 10.

Here, to get a number between 1 and 10, we see that 7.5 could work. However, if we have 7.5, we're disregarding all the zeros that came before it, which can't work. So, we need to take those into account by dividing 7.5 by 10000, which is the same as multiplying 7.5 by [tex]10^{-4}[/tex].

Thus, our final answer is the scientific notation: [tex]7.5 * 10^{-4}[/tex].

Answer:

530.7?

Step-by-step explanation:

Answer: 530.7m

Step-by-step explanation:

The formula for the area of a circle is [tex]A=\pi r^2[/tex]

From the picture we can see that the diameter of the circle is 26m

The r, or radius of the circle is just half the diameter, thus the radius is 13m

Now that we have all the values of the variables, we can solve for A

Plug in 3.14 for π and 13 for r and solve

[tex]A=(3.14)(13)^2[/tex]

[tex]A=(3.14)(169)[/tex]

[tex]A=530.66m[/tex]

Answer:

x = 17

Step-by-step explanation:

This is a right triangle so we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

15^2 + x^2 = (sqrt(514))^2

225 + x^2 = 514

Subtract 225 from each side

225-225 + x^2 = 514-225

x^2 =289

Take the square root of each side

sqrt(x^2) = sqrt(289)

x = 17

Answer:where is the equation

Step-by-step explanation:

Answer:

The answer length is 10 and the width is 8 or the other way around.

Step-by-step explanation: The garden has a area of 80 square feet and since 10 has 2 more than 8 that the answer.

Final answer:

To find the length and width of the garden, set up the equation for the area of a rectangle: width times (width + 2) equals 80. Solving this gives us the width as 8 feet and the length as 10 feet.

Explanation:

The question asks us to find the length and width of a rectangular garden given that its area is 80 square feet and the length is 2 feet more than the width. We can represent the width with the variable w and then express the length as w + 2. To find the dimensions, we write the equation for the area of a rectangle (length × width):

w × (w + 2) = 80

Solving this quadratic equation gives:

w² + 2w - 80 = 0

Factoring the quadratic equation gives:

(w + 10) × (w - 8) = 0

Therefore, the width w could be 8 or -10. Since a negative width doesn't make sense for a garden, we take w = 8 feet as the width. Consequently, the length is w + 2 = 10 feet.

The dimensions of the garden are 8 feet by 10 feet or vice versa.

Answer:

44cm^2

Step-by-step explanation:

We work with area for rectangles using the face of the longer length first as this is the awkward length the perpendicular side to the easy calculation of the square and sits perpendicular to the square.

We choose the longer length and plug in and choose one of the two calculation answers.

11 x 4 = 44

11 x 6 = 66

We see the answer is 44cm^2, so we choose this one.

so the answer is of option C....

Answer to the equation is:

k = -42/2 = -21

Answer:

x = -9.5

y = -2.5

Step-by-step explanation:

to evaluate this linear system of equation, we would say that

let

x = 3y - 2................................................ equation 1

x= -7y + 8.............................................. equation 2

substitute equation 2 into equation 1

3y -2 = 7y + 8

collect the like terms

3y -2 -8= 7y

-10 = 7y -3y

-10 = 4y

divide both sides by 4

-10/4 = 4y/4

-2.5 = y

y = -2.5

put the value value of y into equation 1

x = 3y - 2................................................ equation 1

x = 3(-2.5)  -2

x = -75 - 2

x = -9.5

Answer: 6.72 is greater than 6.69

Step-by-step explanation: 6 and 6 is the same number so we don't have to compare those. And we all know, 72 is always greater than 69 and there is your answer 6.72. Hope you mark me as brainiliest.

6.72 is greater than 6.69.

This question is asking whether 6.72 is greater than or less than 6.69.

When comparing decimal numbers, from left to right, the first digit in 6.72 is 6 and the first digit in 6.69 is also 6.

Since they are the same, move to the next digit.

The second digit in 6.72 is 7 whereas it is 6 in 6.69.

Since 7 is greater than 6, we can therefore conclude that 6.72 is greater than 6.69.

Step-by-step explanation:

V = Bh

V = 24(7)

V = 168 m3

Answer:

i really dont know bro

Step-by-step explanation:

Sample response: Start by calculating the volume of the original prism. The area of the base, B, is 4(6) = 24 m2. Multiply that by the height to get the volume: 24(10) = 240 m3. Now, if you double all of the dimensions, you would have a rectangular prism with a base that is 8 m by 12 m and a height of 20 m. The area of the base, B, is 8(12) = 96 m2. Multiply that by the height to get the volume: 96(20) = 1,920 m3. To compare, look at the ratio of the original prism to the new prism: 96/1,920 = 1/8. The volume increases by 8 times the original volume.

To estimate the difference 7/8 - 6/11, replace each fraction with 1 or 1/2 based on their proximity to 1 or 1/2. The estimated difference is 1/2.

To estimate the difference 7/8 - 6/11, we need to replace each fraction with either 0, 1/2, or 1. Let's find the estimate for each fraction:

7/8 is closer to 1 because the numerator is close to the denominator. So, we replace it with 1.

6/11 is closer to 1/2 because the numerator is half of the denominator. So, we replace it with 1/2.

Now, we can subtract the estimated values: 1 - 1/2 = 1/2.

Therefore, the estimated difference is 1/2.

Answer:

Option K

m is an odd integer and n is an even integer​

Step-by-step explanation:

The sum of intergers when one is even and another is odd results into an even number. Take for example, if x is even and the next number x+1 their sum will be 2x+1. The presence of +1 at the end shows the number is not divisible by 2 hence an odd number.

Practically, if you add 2+3=5 and 2 is even number while 3 is odd, clearly the sum being 5 is an odd number.

Otherwise, if you add two even numbers or two odd numbers the sum will be an even number.

Even numbers can be divided by 2 without leaving a remainder, while odd numbers can't.

The true condition is condition K: m is an odd integer and n is an even integer​

If m is odd and n is odd, then the sum will be even

This means that: Conditions F, G and H cannot be true

As an illustration, we have:

[tex]m + n= 5+ 7[/tex]

[tex]m + n= 12[/tex]

12 is even.

The result will always be even, provided that m and n are odd numbers.

If m is even and n is even, then the sum will be even

This means that: Conditions J cannot be true

As an illustration, we have:

[tex]m + n = 6 + 8[/tex]

[tex]m + n =14[/tex]

14 is even.

The result will always be even, provided that m and n are even numbers.

If m is odd and n is even, then the sum will be odd

This means that: Conditions K is true

As an illustration, we have:

[tex]m + n = 6 + 7[/tex]

[tex]m + n = 13[/tex]

13 is odd.

The result will always be odd, provided that m is odd while, n is even.

Hence: the true condition is:

cuz 10 is bgger than 2.5

Answer:

The graph is missing, so there are two options m∠A = 36.87° or m∠A = 53.13°

Step-by-step explanation:

Assuming that 3 cm, 4 cm and 5 cm are the length of the sides of a triangle, then a right triangle is formed, in which 5 cm is the length of the hypotenuse and 3 cm and 4 cm are the length of the legs.

Angle A is either the angle between 4 cm and 5 cm sides or between 3 cm and 5 cm sides. For the first case:

cos(A) = adjacent/hypotenuse =

cos(A) = 4/5

A = arccos(4/5) = 36.87°

For the second case:

cos(A) = 3/5

A = arccos(3/5) = 53.13°

The measure of angle [tex]\( A \)[/tex] is approximately [tex]\( 53.13^\circ \)[/tex].

Given a right triangle [tex]\( \triangle ABC \)[/tex] with the following side lengths:

[tex]\( AB = 3 \) cm[/tex]

[tex]\( BC = 4 \) cm[/tex]

[tex]\( AC = 5 \) cm[/tex]

We need to find the measure of angle [tex]\( A \)[/tex].

Since [tex]\( \triangle ABC \)[/tex] is a right triangle, and the side lengths 3, 4, and 5 satisfy the Pythagorean theorem [tex](\( 3^2 + 4^2 = 5^2 \))[/tex], we can proceed to use trigonometric ratios to find the measure of angle [tex]\( A \)[/tex].

Using Trigonometric Ratios

The trigonometric function tangent is often used in right triangles. The tangent of an angle in a right triangle is the ratio of the opposite side to the adjacent side.

For angle [tex]\( A \)[/tex]:

[tex]\[\tan(A) = \frac{\text{opposite}}{\text{adjacent}} = \frac{BC}{AB} = \frac{4}{3}\][/tex]

To find the measure of angle [tex]\( A \)[/tex], we use the arctangent (inverse tangent) function:

[tex]\[A = \tan^{-1}\left(\frac{4}{3}\right)\][/tex]

[tex]\[A \approx \tan^{-1}(1.3333) \approx 53.13^\circ\][/tex].
