Hi there,

your question is asking for the angle of the central circle, and the formula is: the two arcs' sum divided by 2

So,

(60 + 40) ÷ 2 = 50

The answer is 50°

Hope I helped :p

Just look at the x and y variables and their exponents and roots. Ignore the rest.

Start with x.
On the left side you have cubic root of x^c.
On the right side you have x^2.

$\sqrt[3]{x^c} = x^2$

$(x^c)^{\frac{1}{3}} = x^2$

$\dfrac{c}{3} = 2$

$c = 6$

Now look at y on both sides and the roots and exponents of y.

$\sqrt[3]{y^5} = y\sqrt[3]{y^d}$

$(y^5)^{\frac{1}{3}} = y^1 \times y^{\frac{d}{3}}$

$y^{\frac{5}{3}} = y^{1 + \frac{d}{3}}$

$y^{\frac{5}{3}} = y^{\frac{3}{3} + \frac{d}{3}}$

$y^{\frac{5}{3}} = y^{\frac{d + 3}{3}}$

$\dfrac{d + 3}{3} = \dfrac{5}{3}$

$d + 3 = 5$

$d = 2$

Answer: Choice C. c = 6; d = 2

The length of a rectangle is 18 centimeters less than five times its width. its area is 35 square centimeters. find the dimensio

Studentka2010 [4]

35 = 5*7
7 = 5*5 -18

The dimensions of the rectangle are: length = 7 cm, width = 5 cm.

_____
It is handy to know your times tables.

___
If you want, you can write a couple of equations and solve them.
.. L = 5W -18
.. LW = 35
Substituting for L, we have
.. (5W -18)W = 35
.. 5W^2 -18W -35 = 0 . . . . put in standard form
.. (W -5)*(5W +7) = 0 . . . . . factor
.. W = 5 or -7/5 . . . . . . . . . we are only interested in the positive solution

The width of the rectangle is 5 cm; its length is 7 cm.

A deli sells a sandwich spread for 6.4per pound. How much do you need to pay for 24 ounces of spread?

Dafna1 [17]

Answer:

You have to pay 9.6.

Step-by-step explanation:

In order to find the answer, first you have to consider that 1 pound is equal to 16 ounces and with that information, you can use a rule of three to find the pounds that 24 ounces represent:

1 pound → 16 ounces

x ← 24 ounces

=(24*1)/16=1.5

Now that you know, that 24 ounces are equal to 1.5 pounds you can multiply the price per pound for the number of pounds to find the amount that you need to pay:

6.4*1.5=9.6

According to this, the answer is that you have to pay 9.6.

50 POINTS!!! The measures of the angles of a triangle are shown in the figure below. Solve for x.

tatyana61 [14]

Answer:

x = 5

Step-by-step explanation:

Add all of the angles together. We know that the third one is 90° because it is a right triangle and the little square indicates a 90° angle.

7x + 16 + 39 + 90 = 180

Simply.
