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].

The correct fraction of the nachos that Jack and Connor ate together is [tex]\(\frac{1}{2}\)[/tex].

To determine the fraction of the nachos that Jack and Connor ate together, we need to add the fractions of the nachos each one ate.

Jack ate [tex]\(\frac{1}{3}\)[/tex] of the nachos. Connor ate [tex]\(\frac{1}{6}\)[/tex] of the nachos.

To add these two fractions, we need a common denominator. The least common multiple (LCM) of 3 and 6 is 6. So, we convert [tex]\(\frac{1}{3}\)[/tex] to a fraction with a denominator of 6 by multiplying both the numerator and the denominator by 2, which gives us [tex]\(\frac{2}{6}\)[/tex].

Now, we can add the two fractions:

[tex]\[\frac{2}{6} + \frac{1}{6} = \frac{3}{6}\][/tex]

This fraction can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 3:

[tex]\[\frac{3}{6} = \frac{1}{2}\][/tex]

Therefore, together, Jack and Connor ate [tex]\(\frac{1}{2}\)[/tex] of the nachos.

Given:

Length = 5 ft

Width = 2 ft

Height = 5 ft

To find:

The cost of total wallpaper.

Solution:

Total surface area = 2(lw + wh + lh)

                               = 2(5 × 2 + 2 × 5 + 5 × 5)

                               = 2(10 + 10 + 25)

                               = 2(45)

Total surface area = 90 ft²

Cost of wallpaper per square foot = $3

Cost of wallpaper for 90 square feet = 3 × 90

                                                             = $270

Therefore total cost of wallpaper is $270.

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

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.

Step-by-step explanation:

V = Bh

V = 24(7)

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.

Answer: OPTION D.

Step-by-step explanation:

By definition, the area of a rectangle can be calculated applying the formula shown below:

[tex]A=lw[/tex]

Where "l" is the length of the rectangle and "w" is the width of the rectangle.

In this case, according to the information given  in the exercise, the kid concludes that the dimensions of the shoes box are the following:

[tex]l=9\ units\\\\w=6\ units[/tex]

Then, substituting values into the formula, you get that the area is:

[tex]A=(9\ units)(6\ units)\\\\A=54\ units^2[/tex]

You need to identify which unit corresponds to this area. It must be Option C or Option D.

 Since [tex]54\ ft^2[/tex] is too big for a shoes box, you can conclude the correct one is the area given in the Option D.

Therefore, you get that thea area is:

[tex]A=54\ in^2[/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:

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:

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:

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].

The complete question is:

What is measure of angle A?
