Answer:

13

Step-by-step explanation:

5 raised 2 = 25

12 raised to 2 = 144

144 + 25 = 169

Square root of 169 = 13

Therefore the hypotenuse is 13 :)

Answer:

You can tell that y=2 when x=4 by looking at the graph

Answer:

y = 2

Step-by-step explanation:

The equation is y = -x+6

Substituting 'x = 4' into this

y = -4+6

Hence, y = 2 when x =4

x = 6

Answer:

-13x+5

Step-by-step explanation:

Distributive Property

-4 (2.5x) + (-4)(-1.25) - 3x

Multiply 2.5 by -4

- 10x - 4 * 1.25 - 3x

Multiply -4 by 1.25

- 10x + 5 -3x

Subtract 3x from -10x

-13x + 5

Answer:

[tex]33\frac{1}{3}[/tex]%

Step-by-step explanation:

We can use a random fraction with numbers that make this problem easier to calculate. We can start with the fraction [tex]\frac{1}{1}[/tex] (1). If its numerator is decreased by 50% and its denominator is decreased by 25%(75% of it), the new fraction will be [tex]\frac{0.5}{0.75}[/tex] , which is the same as 2/3

The percent decrease from 1 to 2/3 is 33.333....% or [tex]33\frac{1}{3}[/tex]%.

You can use variables to solve this problem, but I find it easier to start with the fraction [tex]\frac{1}{1}[/tex] for calculation purposes.

Circumference = 2×π× radius

Circumference = 2 × 3.14 × 3

Circumference = 18.84

Solution for the radius of a circle of radius 3 . I'm sorry if I made a mistake, I am not sure of the solution.

But is there a fee for the question?

These two laws can help you in the question:

Circumference = π× diameter of the circle. Circumference = 2×π× radius

The circumference of the yellow circle should be considered as the 18.84.

Since

The centre circle has a diameter of 3 cm and the difference in the radii of each larger circle is 4 cm

So here the circumference be like

= 2×π× radius

= 2 × 3.14 × 3

= 18.84

hence, The circumference of the yellow circle should be considered as the 18.84.

Answer:

Step-by-step explanation:

FP * PH = GP * EP

If  EP = 2, PG = 12, and FP = 4.

Then 4 * PH = 12 * 2

4 * PH = 12 * 2

step 1 simplify

4 * ph = 4PH

12 * 2 = 24

we now have 4PH = 24

step 2 divide each side by 4

4PH / 4 = PH

24 / 4 = 6

we're left with PH = 6

Answer:

y = -4

Step-by-step explanation:

When y is directly proportional to x,

= y ∝ x

= y = kx

Finding k

the value of y = -2 when x = 4

-2 = k4

k = -2/4

k = -1/2

. What is the value of y when x = 8

Finding y

y = kx

y = -1/2 × 8

y = -4

Answer:

6

Step-by-step explanation:

Let [tex]n = a_{10}[/tex]. We know the formula for the sum of an arithmetic sequence is:

[tex]S_{n} = \frac{n(a_{1}+a_{n} )}{2}[/tex]

Where n is the number term you are finding the sum up to, a1 is the first term, and an is the nth term. We can substitute what we have:

[tex]320=\frac{10(5 + n)}{2}[/tex]

[tex]640=10(n+5)\\64=n+5\\n=59[/tex]

The formula to find the nth term of an arithmetic series is:

[tex]a_{n} = a_{1} + (n-1)d[/tex]

Where d is the common difference. Again, we can plug in what we have;

[tex]59 = 5 + 9d\\9d = 54\\d = 6[/tex]

Answer:

1.4

Step-by-step explanation:

Since we're finding the area, we need to multiply 1.2 times 1.2, which would give us 1.44, and since it says to round to the nearest tenth, we need to round it. If the number is 4 or under, we round down, if it's 5 and up we round up. In this case, we round down- so we end up with 1.4.
