[tex]\frac{1}{16}[/tex]

Step-by-step explanation:

Answer:

[tex]\frac{1}{16}[/tex] is the answer

Step-by-step explanation:

you have to evaluate [tex](7-3)^{-2}[/tex] and the answer comes up to [tex]\frac{1}{16}[/tex]

The triangles ABC and SDC are similar triangles

From the question, we understand points S, C and A are collinear, while line AB and SD are vertical and parallel lines at the either sides of point C.

Hence, Gilligan can conclude that triangles ABC and SDC are similar

To do this, we make use of the following equivalent ratio

[tex]SD : 130 = AB : 23[/tex]

Substitute 90 for AB

[tex]SD : 130 =90 : 23[/tex]

Express as fraction

[tex]\frac{SD}{130} =\frac{90}{ 23}[/tex]

Make SD the subject

[tex]SD =\frac{90}{ 23} * 130[/tex]

[tex]SD =509[/tex]

Hence, Gilligan can conclude that the distance of the ship from the shore is 509 ft

there are 10  different combinations of pairs of colors.

Combinations are ways to choose elements from a collection in mathematics where the order of the selection is irrelevant. Let's say we have a trio of numbers: P, Q, and R. Then, combination determines how many ways we can choose two numbers from each group.

Given, Loris has one of each of the following colors of felt-tip pen in her pencil case: red (R) blue (B) yellow (Y) green (G) purple (P) She pulls out two random pens.

from the formula of combination;

total combination  ⁿCₓ = [tex]\frac{n!}{(n-r)! * r!}[/tex]

Where, n = total numbers

r = desired number out of total

In our case

n = 5 and r = 2

Thus, the Total combination = ⁵C₂

Total combination = 5! / (3! *2!)

total combination = 5 *4 /2 = 10

therefore, There are ten distinct ways to pair the colors together.

Answer:

D) 11 cause it is only found form multiplying 1 and 11

Answer:

According to logarithmic properties.... The right hand side can be written as

log base 7 (180/3).....which is log base 7 60

So according to the question cancel out the log base 7 from both sides....

Then we get 8r + 20 = 60

That is 8r = 40..

That is r = 5......

Therefore the value of r is 5

Answer:

you can because the real cube root of any negative real number is negative.

Step-by-step explanation:

Answer: The reason that we can't have the square (or quartic) root of a negative number is that two negatives always cancel to give a plus; so the square root of a negative number is undefined. ... The Real cube root of any negative Real number is negative.bc. a negativ number multiplied by it self 3 time result negativ too

perimeter of larger triangle = 2×53 + 56 = 162 mm

Answer:

( 3[tex]x[/tex] - 5 ) ( [tex]x[/tex] + 1 )

Step-by-step explanation:

[tex]3x^{2}[/tex] - 2[tex]x[/tex] - 5

(Multiply 3 from [tex]3x^{2}[/tex] with -5)

Product = -15

Sum = -2

(3 times - 5 gives the product '-15' and 3 plus -5 gives the sum -2)

[tex]3x^{2}[/tex] + 3[tex]x[/tex] - 5

3[tex]x[/tex] ( [tex]x[/tex]  + 1 ) - 5 ( [tex]x[/tex] + 1 )

Answer:

v=−27

Step-by-step explanation:

Since v is on the right side of the equation, switch the sides so it is on the left side of the equation.

−6(3v−4)+8v=4(v+7)

Simplify −6(3v−4)+8v

−10v+24=4(v+7)

Simplify 4(v+7).

−10v+24=4v+28

Move all terms containing v to the left side of the equation.

−14v+24=28

Move all terms not containing v to the right side of the equation.

−14v=4

Divide each term by −14 and simplify.

v=−27

The result can be shown in multiple forms.

Exact Form:

v=−27

Answer:

The solution of the first image is: b = √48

The solution of the second image is: c = √125

Step-by-step explanation:

Here we have two triangle rectangles, first, we need to remember the Pythagorean theorem.

For a triangle rectangle with cathetus A and B, and a hypotenuse H, we have the relationship:

A^2 + B^2 = H^2

Where H is the side that is opposite to the right angle (the angle of 90°)

In the first image, we can see that the hypotenuse is equal to 8, and one cathetus is equal to 4.

We want to find the value of b, that is the other cathetus.

Then we have:

4^2 + b^2 = 8^2

b^2 = 8^2 - 4^2

b^2 = 48

b = √48

Second image:

in this case, c is the hypotenuse, a and b are the cathetus.

We know that:

a = 5, b = 10

Then we have the equation:

a^2 + b^2 = c^2

Now we can replace the above values:

5^2 + 10^2 = c^2

25 + 100 = c^2

125 = c^2

√125 = c

Answer:

4 ÷ 10

Step-by-step explanation:

The computation of P is shown below:

If we add two marbles i.e.

= 4 + 6

= 10 marbles

Now if we draw the second marble

P(blue) = Blue marbles ÷ total marbles

= 4 ÷ 10

In the other case

P( blue second given a green first) = 4 ÷ 10

Step-by-step explanation:

Blake bought a new car. He borrowed $12,500 from the bank. After 4 years he had paid off the loan and paid $1500 in interest. What rate did he borrow at?

This is a simple interest question

The formula to find the rate is given as:

Equation:

r = (1/t)(A/P - 1)

t = time = 4 years

P = Principal = $12500

I = Simple Interest = $1500

A = Total Amount = Principal + Simple Interest = $12500 + $1500

= $14000

Calculation:

Solving our equation:

r = (1/4)((14000/12500) - 1) = 0.03

r = 0.03

Converting r decimal to R a percentage

R = 0.03 * 100 = 3%/year
