Layala and Zahra have 2700 marbles in the ratio of 2:7. How many marbles Zahra must have gave away so that they both would have the same number of marbles?

Answers

Answer:

1500

Step-by-step explanation:

Given that :

Total number of marbles held by Layala and Zahra = 2700

Ratio = 2 : 7

Layala's share of marbles : (2 / (2+7)) * 2700

= 2/9 * 2700

= 600

Zahra's share of marble : (7 / (2+ 7)) * 2700

= 7 / 9 * 2700

= 2100

Hence, Zahra must have given away (2100 - x) = 600

2100 - 600

= 1500 marbles, so that both Zahra and Layala have the same number of marbles

When 508,000,000 is written in scientific notation, what will be the value of the decimal number? pizzzz help

Answers

Answer:

5.08 * 10^8

Scientific notation requires that the number be written as a number between one and ten multiplied by the appropriate power of ten. In other words how many times must you multiply 5.08 by 10 in order to get 508,000,000? the answer is eight times so the result is 5.08 * 10^8

Answer:

a. 35°

b. 6 units

Step-by-step explanation:

a. By the property of intersecting tangent and secant outside of a circle, we have:

[tex] m\angle P = \frac{1} {2} \times \bigg(m\widehat{QS} - m\widehat{QR}\bigg) \\\\

m\angle P = \frac{1} {2} \times \bigg(150\degree - 80\degree\bigg) \\\\

m\angle P = \frac{1} {2} \times 70\degree \\\\

\huge\purple {\boxed{m\angle P =35\degree}} \\[/tex]

b.

[tex] PS = PR + RS = 4 + 5 = 9\: units\\[/tex]

By the property of intersecting tangent and secant outside of a circle, we have:

[tex]

PQ^2 = PR\times PS\\\\

PQ^2 = 4\times 9\\\\

PQ^2 = 36\\\\

PQ =\pm \sqrt {36} \\\\

PQ=\pm 6\\[/tex]

Since, PQ can not be a negative number.

So, PQ = 6 units.

F(x) = 4x^4 +5x -3
G(x)= 4x3 - 3x3 +5.
Find (f-g) (x)

Answers

Answer:

After solving we get [tex]\mathbf{(f-g)(x)=-4x^3+7x^2+5x-8}[/tex]

Option A is correct option.

Step-by-step explanation:

We are given :

[tex]f(x) = 4x^2 +5x -3\\g(x)= 4x^3 - 3x^2 +5[/tex]

We need to find (f-g)(x)

(f-g)(x) is equal to  f(x)-g(x)

So, finding (f-g)(x)

[tex](f-g)(x)=f(x)-g(x)\\(f-g)(x)=4x^2+5x-3-(4x^3-3x^2+5)\\(f-g)(x)=4x^2+5x-3-4x^3+3x^2-5\\Combining \ like \ terms:\\(f-g)(x)=-4x^3+3x^2+4x^2+5x-3-5\\(f-g)(x)=-4x^3+7x^2+5x-8[/tex]

So, after solving we get [tex]\mathbf{(f-g)(x)=-4x^3+7x^2+5x-8}[/tex]

Option A is correct option.

The smaller triangle was dilated to form the larger triangle. What is the value of x? A smaller triangle has side lengths of 5, 13, 12. A larger triangle has side lengths of x, blank, 18. 6.9 7.5 10 11

Answers

Answer:

x = 7.5

Step-by-step explanation:

Dilation is a transformation in which the size of a given figure is either increased or decreased by a scale factor.

Given that the length of sides of the smaller triangle are; 5, 13, 12.

Given also that the length of the dilated triangle are; x, blank, 18.

Comparing the length of the last sides of the two triangles, we have;

(scale factor x 12) + 12

                        = ([tex]\frac{1}{2}[/tex] x 12) + 12

                        = 6 + 12

                        = 18

Thus the scale factor for the dilation is [tex]\frac{1}{2}[/tex]. So that:

x = ([tex]\frac{1}{2}[/tex] x 5) + 5

   = 2.5 + 5

   = 7.5

x = 7.5

And also,

blank = ([tex]\frac{1}{2}[/tex] x 13) + 13

          = 6.5 + 13

blank  = 19.5

Therefore, the length of the sides of dilated triangle are: 7.5, 19.5, 18

Answer:

7.5

The angle measures of a triangle are shown:



Angle A: (5x – 5) degrees

Angle B: (3x + 3) degrees

Angle C: (5x) degrees



The sum of the measures of the three angles is equal to 180°. What is the measure of Angle B?

Answers

Answer:

∠ B = 45°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 given angles and equate to 180, that is

5x - 5 + 3x + 3 + 5x = 180, simplify

13x - 2 = 180 ( add 2 to both sides )

13x = 182 ( divide both sides by 13 )

x = 14

Thus

∠ B = 3x + 3 = 3(14) + 3 = 42 + 3 = 45°
