Answer:

$9 per t-shirt

Step-by-step explanation:

First you subtract the cost of the hats from the TOTAL cost of the the T-shrits and the hat.

$83.00-$38.00= $45

Now that you just have the shirts WITHOUT the hat, which is why we subtracted the $38.00, we have to devide. You devide 45 by the number of shirts.

45/5=9

$9 per T-shirt.

Geometry - Law of Sines question #17. Please help, I am stuck.

Flauer [41]

By the law of sines, m∠EFG is such that

sin(m∠EFG) / (8 in.) = sin(m∠G) / (7.5 in)

so you need to find m∠G.

The interior angles to any triangle sum to 180°, so

m∠DEG = m∠D + m∠G + 43°

m∠DEG + m∠D + m∠G = 2 (m∠D + m∠G) + 43°

180° = 2 (m∠D + m∠G) + 43°

137° = 2 (m∠D + m∠G)

68.5° = m∠D + m∠G

But ∆DEG is isosceles, so m∠D = m∠G, which means

68.5° = 2 m∠G

34.25° = m∠G

Then

sin(m∠EFG) = (8 in.) sin(34.25°) / (7.5 in)

m∠EFG ≈ sin⁻¹(0.600325) ≈ 36.8932°

The state fair is a popular field trip destination. This year the senior class at High School A and the senior class at High Sch

SSSSS [86.1K]

Answer:

The number of students in each van = 14

The number of students in each bus = 43

Step-by-step explanation:

Let the number of students that can fill a van be v.

Let the number of students that can fill a bus be b.

The senior class at High School A rented and filled 13 vans and 9 buses with 569 students.

13 vans will have (13v) students

9 buses will have (9b) students

13v + 9b = 569

High School B rented and filled 14 vans and 3 buses with 325 students

14 vans will have (14v) students.

3 buses will have (3b) students.

14v + 3b = 325

Combining these two simultaneous equations

13v + 9b = 569

14v + 3b = 325

Solving simultaneously,

v = 14 students.

b = 43 students.

Hope this Helps!!!

Write an expression with a negative exponent that has a value between 0 and 1/2

aliya0001 [1]

Exponent is a number used to express shorter equation; it is a number that says how many times you are going to multiply the base number.

Exponents have several laws, here are some:
=> x^1 = x
=> x^0 = 1
=> x^-1 = 1/x
=> x^m x^n = X^m+n
=> x^m/x^n = x^m-n

And since we were asked to write an expression with a negative exponent that has a value between 0 and ½
=> 2^ -2 = ½

In triangle ABC shown below, DE is parallel to AC. The following two-column proof with missing statements and reasons proves tha

lianna [129]

Answer:

The correct option is;

C. 3. ∠BDE ≅∠BAC, Corresponding Angles Postulate 4. ∠B ≅ ∠B Reflexive Property of Equality

Step-by-step explanation:

The two column proof can be written as follows;

Statement, Reason

1. $\overline{DE} \parallel \overline{AC}$ , Given

2. $\overline {AB}$ is a transversal , Conclusion from statement 1.

We note that ∠BDE and ∠BAC are on the same side of the transversal relative to the parallel lines, and are therefore, corresponding angles.

Therefore, we have;

3. ∠BDE ≅∠BAC, Corresponding Angles Postulate

Also

4. ∠B ≅ ∠B, Reflexive Property of Equality

In the two triangles, ΔABC and ΔDBE, we have ∠BDE ≅∠BAC and ∠B ≅ ∠B,

From ∠BDE + ∠B + ∠BED = 180°

∠BAC + ∠B + ∠BCA = 180°

Therefore, ∠BED = ∠BCA Substitution property of equality

Which gives;

5, ΔABC ~ ΔDBE, Angle Angle Similarity Postulate

6. BD/BA = BE/BC, Converse of the Side-Side-Side Similarity Theorem
