Answer:

D) 133

Step-by-step explanation:

The total angle of a line is 180 degrees.

If you subtract angle FBE from line FD, you will get angle EBD.

180-47= 133.

Answer:

14

Step-by-step explanation:

As we can see BD is the median of the Triangle ABC

So it breaks into two equal parts

AD = 7

And CD = 7

So

AC = AD + CD

= 7 + 7

= 14

Hope it will help :)

Answer:

A= 18

Step-by-step explanation:

To find the height, find the blocks inside the shape that is completely attached (they have to be in a straight vertical line).  In this case, you can see that three vertical blocks in the middle of the shape is completely attached.  That means your height is 3.

To find the width, look at the how many horizontal boxes make up the top.  6 block inside the shape corispond with 6 blocks on top of the shape, so the width is six.

Multiply 6 by 3 to get 18.

Please find answers in the explanation below

Step-by-step explanation:

4. Each unlabelled opposites are positioned at a 0.5 interval. That means each division in between 0 and 1, 1 and 2, 2 and 3, 3 and 4 are 0.5. So we have 0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4

Same idea is applicable on the negative side of the graph. We have 0, -0.5, -1, -1.5, -2, -2.5, -3, -3.5, 4.

5. Like 4 above, each unlabelled opposite is positioned at an 0.5 or 1/2 interval.

So we have, 0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4 (for the positive side) and 0, -0.5, -1, -1.5, -2, -2.5, -3, -3.5, 4 (for the negative side).

6a.

A positive number is one greater than zero while a negative number is one lesser than zero. So we have -0.5 and 0.5

6b. -0.4, 0.4

6c. -3.5, -3 1/2

Answer:

x=6

Step-by-step explanation:

2 step equations

Answer:

11.3

Step-by-step explanation:

First solve how many grams of each mineral you need.

To do this use this equation

[tex]\frac{3}{5} =\frac{x}{y} ; x+y=400[/tex]

Solve the system of equations to get

x=150, y=250

Since there are 1000 grams in 1 kg then the amount of kg of each material you need will be

[tex]x=\frac{150}{1000}; y=\frac{250}{1000}[/tex]

So you need to 0.15 of a kg of mineral a and 0.25 kg of mineral b.

Multiply 0.15 by 42 to get the amount of money needed to buy mineral a.

0.15*42=6.3

Multiply 0.25 by 20 get the amount of money needed to buy mineral b.

0.25*20= 5

Add them to get the final amount

6.3+5=11.3

Answer: 6 cm

Step-by-step explanation:

Total surface area of cubical box = [tex]6a^2[/tex] , a= edge length of cube   (i)

As per given ,

Total surface area of one box  = [tex]\dfrac{\text{Cost of polishing}}{\text{Rate} \times\text{Number of boxes}}[/tex]

[tex]=\dfrac{151200}{20\times35}\\\\=\dfrac{151200}{700}\\\\= 216\ sq. cm[/tex]   (ii)

Now from (i) and (ii) ,

[tex]6a^2 = 216\\\\\Rightarrow\ a^2= 36\\\\\Rightarrow\ a= 6 \text{ [By taking square root on both sides]}[/tex]

Hence, the edge of each cubical box​ = 6 cm.

Answer:

B (had to be 20 leeters long ;-;;;;;;;;;;;;;;;;;;;;)

Step-by-step explanation:

Step-by-step explanation:

L * M = 452,199

L * (M + 1) = 454,322

Therefore L * (M + 1) = L * M + L.

=> 454,322 = 452,199 + L, L = 2,123.

Hence L² = 2,123² = 4,507,129.

Step-by-step explanation:

x²y = k, where k is a real constant.

When x = 3.5, y = 8.

=> (3.5)²(8) = k, k = 98.

When y = 8/9,

we have x²(8/9) = (98).

=> x² = 110.25

=> x = 10.5 or x = -10.5.

Since we want the negative value,

the answer is x = -10.5.

The required negative value of variable x when y = 8/9 is -10.5. To understand the calculations, check below.

Important information:

Using the given inverse proportional statement, we get

[tex]y\propto \dfrac{1}{x^2}[/tex]

[tex]y=\dfrac{k}{x^2}[/tex]     ...(i)

Substitute [tex]x=3.5,y=8[/tex].

[tex]8=\dfrac{k}{3.5^2}[/tex]

[tex]8=\dfrac{k}{12.25}[/tex]

[tex]8\times 12.25=k[/tex]

[tex]98=k[/tex]

Substitute [tex]k=98[/tex] in (i).

[tex]y=\dfrac{98}{x^2}[/tex]

Substitute [tex]y=\dfrac{8}{9}[/tex].

[tex]\dfrac{8}{9}=\dfrac{98}{x^2}[/tex]

[tex]x^2=98\times \dfrac{9}{8}[/tex]

[tex]x^2=110.25[/tex]

[tex]x=\pm \sqrt{110.25}[/tex]

[tex]x=\pm 10.5[/tex]

We need only negative value.

[tex]x=-10.5[/tex]

Therefore, the required value of variable x is -10.5.

Answer:

35 ft

Step-by-step explanation:

Since E and F are both midpoints, you can create a midsegment between them. A midsegment is half the length of the line segment parallel to it (the 70 ft) So:

70/2=35

Answer:

x = 48

Step-by-step explanation:

x/2+21=45

subtract 21 on both sides

x/2 + 21 - 21 = 45  - 21

x/2 = 24

Multiply by 2 on both sides

x/2 * 2 = 24 * 2

x = 48

Check

48/2 + 21 = 45

24 + 21 = 45

45 = 45 CORRECT

Answer:

7 is the answer

Step-by-step explanation:

They are based on 7th hrs.

Answer:

7

Step-by-step explanation:

If

4=28

Then let 1 be = x

so;

4=28

1=x

x=¼×28

x=7

This is because 28 can be divided by 4, 7 times.

Answer:

y=7-4x/-1

y=-7+4x

substituting y=-7+4x

-3x+4(-7+4x)=24

-3x-28+16x=24

-3x+16x-28-24=0

13x-52=0

13x=52

x=52/13

x=4

substituting x=4

-3x+4y=24

-3(4)+4y=24

-12-24+4y=0

-36+4y

4y=36

y=36/4

y=9

Negative Correlation

Step-by-step explanation:

there is a negative correlation between the number of hours you sleep in and the number of hours you are awake during the day as the longer you are either awake or asleep the less time you will be doing the other thing

Here is a graph I made that will hopefully help you understand.

Even if I switched around the label for the x or y-axis, the correlation would still remain the same because the more you stay asleep, the less you will be awake and vice versa.
