Answer:

8.45 grams

Step-by-step explanation:

In a science experiment, Shelly has to weigh a compound in grams. The balance in her school measures in milligrams (mg). Shelly finds that the weight of the compound is 8,450 mg. What is the value in grams (g) that Shelly should enter?

1 mg = 0.001 g

8450 mg = x

Cross Multiply

= 8450 × 0.001 g

= 8.45 g

Therefore, Shelly should enter 8.45 grams

Answer:$171.29

Step-by-step explanation:

if the tip amount is around $28.55 and your putting 20% it would $171.29 but it would determine how many people they are.

Answer:

that is correct!!! and good job

Answer:

answer is 9

Step-by-step explanation:

1st method: Proportion

15/100 = n/60

cross-multiply to get:

100n = 900

n = 900/100

n = 9

2nd method: Convert % to Decimal and Multiply

.15 × 60 = 9

Answer:

x = 42

Step-by-step explanation:

y = x/7 + 15 ; y = 21

21 = x/7 + 15

21 - 15 = x/7

6 = x/7

x = 6 × 7

x = 42

Thus, The answer is 42

Answer:

?

Step-by-step explanation:

Answer:

Option D

3)

[tex] Cos 60°= \frac{1}{2} = \frac{Adjacent} {Hypotenuse} = \frac{y} {10} \\\\ 2y=10 \\\\ y=5 [/tex]

Now, use Pythagoras theorem to find x

[tex] x^2+y^2=10^2 \\\\ \to x^2+5^2=10^2 \\\\ \to x^2+25=100 \\\\ \to x^2 = 100-25 \\\\ \to x^2= 75 \\\\ \to x= \sqrt{75} \\\\ \bf 5 \sqrt{3} [/tex]

Similarly,

4)

[tex] Sin 45°= \frac{1}{\sqrt{2}} = \frac{Opposite} {Hypotenuse} =\frac{2 \sqrt{2}} {a} \\\\ a= 2 \sqrt{2} \times \sqrt{2} \\\\ a=4 [/tex]

Now, use Pythagoras theorem to find b

[tex] b^2+(2 \sqrt{2}) ^2=a^2 \\\\ \to b^2+8=4^2 \\\\ \to b^2=16-8 \\\\ \to b^2 = 8\\\\ \to b= \sqrt{8} \\\\ \bf b=2 \sqrt{2} [/tex]

You can solve all of them in a similar way.

Answer:

[tex]A+B+C=130[/tex]

[tex]F+E+D=273[/tex]

Step-by-step explanation:

From the question we are told that:

Dimension of ABC

A=9

B=11

C=110

Dimension of FED

D=231

Generally the equation for the similar triangles is mathematically given by

[tex]\frac{A}{F}=\frac{B}{E}=\frac{C}{D}[/tex]

Therefore solving for F

[tex]\frac{9}{F}=\frac{110}{231}[/tex]

[tex]F=\frac{9*231}{110}[/tex]

[tex]F=18.9[/tex]

Therefore solving for E

[tex]\frac{11}{E}=\frac{110}{231}[/tex]

[tex]E=\frac{11*231}{110}[/tex]

[tex]E=23.1[/tex]

Measure of [tex]\triangle ABC[/tex]

[tex]A+B+C=130[/tex]

Measure of [tex]\triangle FED[/tex]

[tex]F+E+D=273[/tex]

Answer:

G.fourth grade

Step-by-step explanation:

The media is the line inside the box that’s the middle

In third grade the median is 50 but in fourth grade the median is 52 so therefore your answer is fourth grade

And the reason I know this is because I’m in 7th and have the exact same question

Answer:

X-Axis

Step-by-step explanation:

The Y changed from negative to positive meaning that it reflected across the X-Axis

(っ◔◡◔)っ ♥ Hope It Helps ♥

Answer:

x axis

Step-by-step explanation:

Since the x value stayed the same and the y value changed, we can tell that the point was reflected over the x axis.

Another way to think of it:

If you draw a graph and put both points on the graph, try to fold the paper on one of the axis's. Whichever fold causes the two points to touch, is the axis that point D was reflected on.

Answer: x^3+5x^2

Step-by-step explanation:

Answer:

Alternate interior angles have the same measure. As we know that 'angle 1 ' and 50° are alternate interior angles hence they must be equal. Also we now that sum of all the angles of a triangle is equal to 180°. Hence, m∠2=15°

Step-by-step explanation:

Answer:

90°

Step-by-step explanation:

This is a kite.

The angle measures of the diagonals (the lines in the middle) are always going to be 90° if they looks like this without any other measures. This goes for all other quadrilaterals as well.

m∠2=90°

Answer:

1.) y3

Step-by-step explanation:

Answer:

sum of angles in a triangle is 180

so 70+60+ 8x+2 = 180

132+ 8x = 180

8x = 180-132

x = 48/8

x= 6

then find the angle by substituting value of x

8x + 2

8*6 + 2

= 50°

Answer:

If you are round the answer, you would get 15.7 cm. If not, you would get around 16 cm.

Step-by-step explanation:

The diameter is 5 and π is 3.14. You multiply those two together to get 15.7 cm. If the teacher asks to round, you will get 16 cm.

Answer:

4 and 3 are coefficanta and 12 will be a constant.

if 4 and 3 are being shared by the variable they would be coefficants
