75% of the bracelets are blue

Answer:

75%

Step-by-step explanation:

We know that Mary made twelve bracelets and also that nine of them are blue, we are then asked to find the percentage of the bracelets that are blue.

To solve, first get a fraction of how many of the bracelets are blue. Since there are twelve in total, 12 will be our denominator, and since 9 are blue, 9 will be our numerator.

\frac{9}{12}

Now to turn this into a percentage, we need to reduce this fraction to the lowest we can. Both numerator and denominator are divisible by 3, so do as followed :

\frac{9/3}{12/3}

\frac{3}{4}

Divide 3 by 4 :

3/4 = 0.75

Multiply 0.75 by 100 to get our percentage :

0.75 * 100 = 75%

PtichkaEL [24]

Answer:

1. B

2.C

Step-by-step explanation:

A plot of land in the shape of a vertical ellipse. The equation of the ellipse is

\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}=1.

If the foci are 8 feet from the center, then c=8.

If the plot of land is 34 feet across the vertical axis, then 2b=34\Rightarrow b=17.

Use formula c=\sqrt{b^2-a^2} (because ellipse is vertical, then b>a) to find a:

8=\sqrt{17^2-a^2}\Rightarrow a^2=289-64=225,\ a=15.

Then  the plot of land is 2a=30 ft across the other axis.

If b>a, the eccentricity of the ellipse is

e=\dfrac{c}{b}=\dfrac{8}{17}\approx 0.471.

Create a two-column proof: Given: EAB and DCB are two right triangles. The figure has BED≅ BDE. Point B is the midpoint of segme
Umnica [9.8K]

The two-column proof that shows that ΔEAB ≅ ΔDCB by SAS congruence theorem is explained below.

<h3>What is the the SAS Congruence Theorem?</h3>

The Side-angle-side congruence theorem (SAS) that states that two triangles that are have two pairs of corresponding congruent sides and a pair of included corresponding congruent angles are congruent to each other.

<h3>What is an Isosceles Triangle?</h3>

Any triangle with two equal base angles is referred to as an isosceles triangle, The sides opposite these base angles are also congruent to each other.

Given the diagram below, the proof is expressed as follows:

Statement 1: ΔEAB and ΔDCB are two right triangles

Reason 1: Given

Statement 2: ∠EAB  ≅ DCB

Reason 2: Right angles

Statement 3: ∠BED ≅ BDE

Reason 3: Given

Statement 4: ΔBED is an isosceles triangle

Reason 4: Definition of isosceles triangle

Statement 5: BE ≅ BD

Reason 5:  Definition of isosceles triangle

Statement 6: ΔEAB ≅ ΔDCB

Reason 6: SAS
