Answer:

Social Studies

Step-by-step explanation:

The social studies bar starts just under 85 in 2000 and drops to just below 80 by 2003, showing a decline of approximately 5 points.

English scores also fell, beginning slightly above 75 (around 77) and ending just under 75, a decrease of about 3 points. Hence, social studies experienced the greatest reduction.

En la materia de estudios sociales, la tendencia es una disminución gradual. En cuanto a las demás asignaturas, los resultados varían a lo largo de los años.

Three ships, A, B, and C, are anchored in the atlantic ocean. The distance from A to B is 36.318 miles, from B to C is 37.674 mi
Leona [12618]

Let's sketch the triangle.

The sides are a= 37.674 miles

b= 11.164 miles

c= 36.318 miles

We'll apply the cosine rule for angle calculations

(since the sine law cannot be employed without knowing any angle measurements).

The cosine law is given by

c^{2} = a^{2} +b^{2} -2ab cos C

Substituting the values results in

(36.318)^{2} = (37.674)^{2} + (11.164)^{2} - 2(37.674)(11.164). Cos C

1318.997 = 1419.33 + 124.634 - 841.184. Cos C

1318.997 = 1543.964 - 841.184. Cos C

841.184. Cos C = 1543.964-1318.997

841.184. Cos C = 224.967

Cos C = \frac{224.967}{841.184}

cos C = 0.267

C = 74.48°

We can find angle A using the sine law

\frac{a}{SinA} = \frac{c}{Sin C}

\frac{37.674}{Sin A} = \frac{36.318}{Sin 74.48}

Sin A = \frac{37.674. sin 74.48}{36.318}

Sin A = \frac{37.674 X 0.963}{36.318}

Sin A = 0.998

A= sin^{-1} (0.998)

A = 87.38°

The third angle B can be determined by calculating 180° minus the sum of angles A and C

B = 180-(74.48 + 87.38)

B = 180 - 161.86

B = 18.14°

Thus, we have calculated all three angles (as shown in the attached figure).

Another project on Kickstarter for an iPad stylus raised 1,253% of their goal, raising a total of $313,490 from 7,511 supporters
Svet_ta [12734]

Answer:

The initial goal was $25019.154.

Step by step Explanation:

Assuming the original goal is denoted as x.

As stated

Another Kickstarter initiative for an iPad stylus secured 1,253% of its target, accumulating a total of $313,490.

1253% can be expressed as a decimal.

= \frac{1253}{100}

= 12.53

Thus, the equation is rearranged to

12.53 × x = 313490

12.53x = 313490

x = \frac{313490}{12.53}

x = $ 25019.154

This means the initial goal stands at $25019.154.

Can the sum of two mixed numbers be equal to two
lawyer [12517]
No, mixed numbers must include both a whole number and a fraction to qualify as such. If a fraction were present, it wouldn’t sum to two due to the presence of the 1's ❤️.
