Salma is in charge of decorating the school gym for a party. She has budgeted some money for decorations. Balloons (x) cost $2.5

Artyom0805 [142]

Answer:

your answer would be A.

Step-by-step explanation:

Already you know that answers b and d are not an option because it is saying she can use OVER 45 dollars. So she has to use EQUAL or less then 45 dollars. So the answer has to be A or C. In answer C it is saying she can spend MORE then 2.50 for a bunch where she cant. She has to spend exactly or less then that amount. So your answer is A.

A student solved for the radius of a circle with a circumference of 12π

padilas [110]

Answer:

Step 4 is incorrect he did not divide correctly from step3 to step 4

Step-by-step explanation:

The circumference of a circle is

C = 2 * pi *r

We know the circumference is 12 pi

12pi = 2 pi *r

Divide each side by 2 pi

12 pi/2pi = 2pi r/ 2pi

6 = r

From step 3 The student did not cancel the pi in the top and the bottom on the right hand side to isolate r

In step 4 he got 6 =pi r instead of pi

In triangle ABC, angle = 90 degrees. AC = 7, BC = 12. AB = _______ Measure of angle A = _______ Measure of angle B = _______

Ulleksa [173]

Answer:

AB = 13.89

Measure of angle A = 59.74°

Measure of angle B = 30.26°

Step-by-step explanation:

The given parameters are;

∠C = 90°

AC = 7

BC = 12

Part 1

Hence, the question has the dimensions of the two adjacent sides of the right angle (angle 90°)

From Pythagoras theorem, we have;

A² = B² + C²

Where, A is the opposite side to the right angle, hence;

In the ΔABC,

AB ≡ A

Therefore;

AB² = AC² + BC² = 7² + 12² = 193

∴ AB = √193 = 13.89

Part 2

∠A is the side opposite side BC such that by trigonometric ratios

$tan \angle A = \frac{Opposite \, side \, to \, angle \, A}{Adjacent \, side \, to \, angle \, A} = \frac{BC}{AC} = \frac{12}{7} = 1.714$

∴ ∠A = Arctan(1.714) or tan⁻¹(1.714) = 59.74°

Part 3

∠B is found from knowing that the sum of the angles in a triangle = 180°

∴ ∠A + ∠B + ∠C = 180° which gives

59.74° + 90° + ∠B = 180°

Hence, ∠B = 180° - (59.74° + 90°) = 180° - 149.74° = 30.26°.

Solve each compound inequality (show your work!)

zimovet [89]

Answer: -1 < x < 8

x = 3

x ≠ 2

Step-by-step explanation:

Isolate x in the middle. Perform operations to all 3 sides.

-6 < 2x - 4 < 12

+4 +4 +4

-2 < 2x < 16

÷2 ÷2 ÷2

-1 < x < 8

**************************************************************************

Isolate x. Solve each inequality separately. Remember to flip the sign when dividing by a negative.

4x ≤ 12 and -7x ≤ 21

÷4 ÷4 ÷-7 ÷-7

x ≤ 3 and x ≥ 3

Since it is an "and" statement, x is the intersection of both inequalities.

When is x ≤ 3 and ≥ 3? when x = 3

****************************************************************************

Isolate x. Solve each inequality separately.

15x > 30 or 18x < -36

÷15 ÷15 ÷18 ÷18

x > 2 or x < 2

Since it is an "or" statement, x is the union of both inequalities.

When we combine the inequalities, x is every value except 2.

x ≠ 2
