Natalie had 64 beads. She used 24 beads to make a bracelet. She used 7/8 of the remaining beads to make a necklace. How many bea
Eddi Din [679]

Answer:

Natalie have left with 5 beads.

Step-by-step explanation:

Given:

Natalie had 64 beads. She used 24 beads to make a bracelet. She used 7/8 of the remaining beads to make a necklace.

Now, to find the beads does Natalie have left.

<em>Total beads Natalie had = 64 beads.</em>

<em>And beads she used to make a bracelet = 24 beads</em>.

So, the remaining beads are = 64-24=40\ beads.

Now,<em> the beads she used to make a necklace</em> = 40 of \frac{7}{8}

                                                                             = 40\times \frac{7}{8}

                                                                             = \frac{280}{8}

                                                                             = 35\ beads  

Hence, the beads Natalie have left = remaining beads - beads used to make necklace.

The\ beads\ Natalie\ have\ left\ =\ 40-35

The\ beads\ Natalie\ have\ left\ =\ 5\ beads.

Therefore, Natalie have left with 5 beads.

(05.02 LC) Given triangle ABC, which equation could be used to find the measure of ∠C?
Sidana [21]

Answer:

D. sin m∠C = 2 square root of 5 all over 5

Step-by-step explanation:

The triangle ABC is a right angled triangle. The angle ∠C is where we are asked to find.  The side AB measures 6 , AC measures 3 and the side BC measures 3√5.

The longest side of a right angle triangle is the hypotenuse, that means the side with length  3√5 is the hypotenuse.

Therefore side BC is the hypotenuse side and we are asked to find the angle C. AB is the opposite side while AC is the adjacent side.

Using

sin C = opposite/hypotenuse = 6/3√5 = 2/√5 = 2√5/5

cos C = adjacent/hypotenuse = 3/3√5 = 1/√5

How does a globe represent the fact that there are no parallel lines in elliptical geometry? A. The equator is not parallel to a
Vlada [557]

Answer:

The correct option is;

D. The geodesics connecting the North as South poles intersect at both of the poles

Step-by-step explanation:

As an analog to the straight line, the geodesic of a curved surface is the shortest path between two points on the curved surface

Whereby the Earth is assumed to be spherical, the geodesics around the Earth would then be closed circles and like the longitude and latitude, will meet at the North and South poles

However given that the Earth is an Oblate ellipsoid, Euclid's parallel postulate is not in effect and the geodesics connecting the North and South Poles Intersect at both poles.
