Answer:

0.004129

Step-by-step explanation:

I'm not sure if you meant this by usual form, if it isn't please let me know and I will redo it for you :)

First,

10^-3 can be simplified to 0.001

Second,

4.129 multiplied by 0.001 is 0.004129.

Hope this helps!!

If it is correct, can you mark me brainliest please?

Meg makes a dot plot for the data 9, 9, 4, 5, 5, 3,<br> 4,5, 3, 8, 8, 5. Where does a gap occur?

Papessa [141]

The gap consists of the values 6 and 7.

Check out the dot plot below to see what I mean. We have one cluster on the left from 3 to 5. Then another cluster on the right from 8 to 9.

Given:

The inequality is

$c\leq 7$

Where, c is the number of cars in the parking lot.

To find:

The graph for the given inequality.

Solution:

We have,

$c\leq 7$

Here, the value of c can be any real number less than or equal to 7. But c is the number of cars, so c must be a non-zero integer.

Since, all the non-zero integer values less than or equal to 7 are included in the solution set, therefore, c = 0,1, 2,3,4, 5,6,7.

In the graph of the given inequality, there are close circles on 0,1, 2,3,4, 5,6,7 as shown in option D.

Therefore, the correct option is D.

In the construction of a segment congruent to a given segment shown, what is CD?

pogonyaev

If segments AB and CD are congruent, then they have equal lengths:

5x-2=2x+7.

Solve this equation.

1. Separate terms with x and without x in different sides:

5x-2x=7+2,

3x=9.

2. Divide by 3:

x=3.

Then CD=2x+7=2·3+7=6+7=13.

Answer: correct choice is B.

Using suitable rearrangement find the sum of -5 + 7/10 + 3/7 + (-3) + 15/4

Mashutka [201]

Answer:

-4.88

Step-by-step explanation:

-5+(-3) = (-8)

7/10 = 98/140

3/7 = 60/140

15/4 = 525/140

525/140 + 60/140 + 98/140 = 683/140

683/140 = 4 123/140

4 123/140 = 4.88 (2dp)

4.88+(-8) = -4.88

Building A is 464 feet tall and Building B is 321 feet tall. Dale is standing between the buildings. The angle of elevation from

alex41 [277]

Answer:

The distance between the buildings is:

D = 413.3 ft

Step-by-step explanation:

Ok, here we have two triangle rectangles, such that these triangle rectangles share a common vertex which is Dale.

One of the triangles, let's call it triangle A, has the catheti:

Distance between Dale and Building A = d1

Height of Building A = 464 ft

The other triangle (triangle B) has the catheti:

Distance between Dale and Building B = d2

Height of building B = 321ft

We want to find the distance between the buildings, which is equal to d1 + d2.

Then we want to find d1 and d2.

For triangle A:

We know that the angle at the vertex where Dale is standing, is 75°

Then the adjacent cathetus is d1, and the opposite cathetus is the height of building A.

Remember that:

Tan(θ) = (opposite cathetus)/(adjacent cathetus)

Then:

Tan(75°) = (464 ft)/(d1)

d1 = (464 ft)/(Tan(75°)) = 124.3 ft

Now for triangle B, the angle at the vertex where Dale is standing is 48°.

from this vertex, we have d2 as the adjacent cathetus and the height of build B as the opposite cathetus.

Then:

Tan(48°) = 321ft/d2

d2 = (321ft)/(Tan(48°)) = 289ft

Then the distance between the buildings is:

D = d1 + d2 = 124.3 ft + 289ft = 413.3 ft
