Answer:

58.3

Step-by-step explanation:

Answer:

Your answer is -6.

Step-by-step explanation:

Simplify 2(2x+3) to get 4x+6  

Then simplify -6(x+9) to get -6x-54

Now you have 4x+6=-6x-54

Move all of the coefficients to one side:

10x+6=-54

Move all of the constants to the other side:

10x=-60

Divide each side by 10:

10/10x=-60/10

To get your answer of -6.

Step-by-step explanation:

Chelsea is making a kite in the shape of a triangle. To determine if the triangle is a right triangle, Chelsea completed the following steps.

Step 1:

Find the side lengths of the triangle: 30 inches, 24 inches, 18 inches.

Step 2:

Substitute the values into the Pythagorean theorem: 18 squared + 24 squared = 30 squared.

Step 3:

Combine like terms: (18 + 24) squared = 30 squared.

Step 4:

Evaluate each side: 1764 not-equals 900.

Chelsea says the triangle is not a right triangle. Which best describes the accuracy of her explanation?

The triangle is actually a right triangle. In step 2, Chelsea incorrectly substituted the values into the Pythagorean theorem.

The triangle is not a right triangle, but in step 2 Chelsea incorrectly substituted the values into the Pythagorean theorem.

The triangle is actually a right triangle. In step 3, Chelsea incorrectly rewrote the expression on the left side of the equation.

The triangle is not a right triangle, but in step 3, Chelsea incorrectly rewrote the expression on the left side of the equation.

Answer:

3/5 or three fifths

Answer:

62 cookies

Step-by-step explanation:

If we take 40 and divide by 24 we get 1.6 that means for every normal cookie there is 1.6 chocolate cookies. With that we can simply just divide 100 by 1.6 to get 62.5 I chose to round down.

Answer:

32 solid balls are formed.

Step-by-step explanation:

Let suppose that volume of the cone is equal to the total volume of balls, of which we derive the following formula:

[tex]\frac{1}{3}\cdot \pi\cdot R^{2}\cdot h = \frac{1}{6}\cdot \pi \cdot n \cdot D^{3}[/tex] (1)

Where:

[tex]R[/tex] - Radius of the base of cone, measured in centimeters.

[tex]h[/tex] - Height of cone, measured in centimeters.

[tex]D[/tex] - Diameter of sphere, measured in centimeters.

[tex]n[/tex] - Number of balls, no unit.

Then, we clear the number of balls:

[tex]2\cdot R^{2}\cdot h = n\cdot D^{3}[/tex]

[tex]n = \frac{2\cdot R^{2}\cdot h}{D^{3}}[/tex]

If we know that [tex]R = 12\,cm[/tex], [tex]h = 24\,cm[/tex] and [tex]D = 6\,cm[/tex], then the number of balls is:

[tex]n = \frac{2\cdot (12\,cm)^{2}\cdot (24\,cm)}{(6\,cm)^{3}}[/tex]

[tex]n = 32[/tex]

32 solid balls are formed.

Answer:

1) 35

2) 125

Step-by-step explanation:

1)

angle adc = x

x+ 90 + 20 = 180                (triangke sum property)\

x = 180 - 110 = 70

angle bdc = 70/ 2 = 35          ( the median cuts the angle into 2)

2) cbd = x = 125

x + c + bdc = 180

x + 35 + 20 = 180

x = 180 - 55 =  125

I hope im right!!!

Answer:

65.9734457254 or 65.97

Step-by-step explanation:

c= pi x diameter

c= pi x (10.5 x 2)

c= pi x 21

= 65.9734457254

Answer:

66 in approx

Step-by-step explanation:

Given data

Radius= 10.5 inches

The circumference is given as

C= 2πr

Substitute

C=2*3.142*10.5

C=65.982

Hence the Circumference is 66 in approx

Answer: h(5)=-44

Step-by-step explanation:

Given

h(t)=-10x+6

h(?)=-44

Substitute the [-44] value to the first equation

-44=-10x+6

Subtract 6 on both sides

-44-6=-10x+6-6

-50=-10x

Divide -10 on both sides

-50/-10=-10x/-10

x=5

Hope this helps!! :)

Answer:

∠ZXY = 57°

Step-by-step explanation:

According to angle sum property of a triangle, sum of all the angles of the triangle is [tex]180[/tex]°.

In ΔXYZ,

∠XYZ + ∠YZX + ∠ZXY = 180°

Put ∠XYZ = 104°, ∠YZX = 19°

104° + 19° + ∠ZXY = 180°

123° + ∠ZXY = 180°

∠ZXY = 180° - 123°

∠ZXY = 57°

Therefore,

∠ZXY = 57°

Volume = (6x^3)(12x^3)(2x^3)=144x^9

Answer:

you will need to cut off 15.4 cm

Step-by-step explanation:

35.87×2=71.74

71.74-56.34=15.4

Answer:

x = 55

Step-by-step explanation:

ABCD is a paralellogram, m∠ABC = 2x + 15, m∠BCD = x

m∠ABC + m∠BCD = 180° (same side interior angles)

2x + 15 + x = 180

3x + 15 = 180 -15

3x = 165

x = 55

Answer:

company a

Step-by-step explanation:

It is probably company a because if you make a box and whisker plot in your head the median of 6 would be more in between 3 and 10 than 9. If the median were 9 it would probably be skewed. If 6 is near the middle the box and whisker plot would look more symmetric

Answer:

14.40 dollars

Step-by-step explanation:

72 divided in 5

Answer:

1 and 1/6

Step-by-step explanation:

To rename a fraction you multiply both numbers by however many times the original denominator goes into the new one.

2 goes into 6 three times.

1 times 3 is 3

and 2 times 3 is 6

so 1/2=3/6

3 goes into 6 twice

2 times 2 is 4

and 2 times 3 is 6

so 2/3=4/6

to add fractions you add the numerators while keeping the denominators the same.

3+4=7 so:

3/6+4/6=7/6

6/6=1

so 7/6 contains 1 whole

once you take that out you have 1/6 left over

Answer:

9 1/3 feet (I think)

Step-by-step explanation:

I imagined it as a grid.

Your friend moves to point (16,12)

You move to point (-12,9)

Then you set up your equation and solve.

[tex]\frac{16 + 12}{12-9}[/tex]

[tex]\frac{28}{3}[/tex]

9 1/3

Hope this helps :)

So stats. The using the results im guessing there are 20 cards since we aren't told otherwise. since we drew diamond roughly 4 out of the 20 cards we have a 20% or 1/5 chance of drawing diamond randomly

Answer: 1/5

Step-by-step explanation:

Add all 8+3+5+4=20

4/20

simplify by 2

4/2= 2  20/2= 10 = 2/10

simplify by 2 again

2/2= 1  10/2=5

=1/5

Ok im going on your page to see the question

Answer:

it on web I had this question once

Step-by-step explanation:

put it in web and you be find

The amount that Sam get (the share of Sam) is £120

Suppose that we've got two quantities with measurements as 'a' and 'b'

Then, their ratio(ratio of a to b) a:b or [tex]\dfrac{a}{b}[/tex]

We usually cancel out the common factors from both the numerator and the denominator of the fraction we obtained. Numerator is the upper quantity in the fraction and denominator is the lower quantity in the fraction).

Suppose that we've got a = 6, and b= 4, then:

[tex]a:b = 6:2 = \dfrac{6}{2} = \dfrac{2 \times 3}{2 \times 1} = \dfrac{3}{1} = 3\\or\\a : b = 3 : 1 = 3/1 = 3[/tex]

Remember that the ratio should always be taken of quantities with same unit of measurement. Also, ratio is a unitless(no units) quantity.

Same thing happens for 3 quantities and more such quantities.

So if its given that Oli, Sam, and Tim's share (total  £360) are in the ratio 3:2:1, that means some common factor (lets call it 'x') must be cancelled off as 3+2+1 don't equate to 360.

So, we have:

Their total evaluates to 360 (in euros).

(we don't write symbols like of currency generally, and understand it from context. Also, sign of multiplication is often hidden if there are non numeric symbols and numbers being multiplied are written together)

Thus, we get:

[tex]3x + 2x + x = 360\\(3+2+1)x = 360\\6x = 360\\\\\text{Dividing both the sides by 6}\\\\\dfrac{6x}{6} = \dfrac{360}{6}\\\\x = 60[/tex]

Thus, we get:

Thus, the amount that Sam get (the share of Sam) is £120
