159 degrees is the answer
Elan Coil [88]2 years ago
3 0

Answer:

a. (5x+75)°

b. x = 21

c. X° = 21° and (4x+75)°= 159°

Step-by-step explanation:

A. Combine like integers.

B. (5x+75)°=180° Because they are suplementary angles.

   5x°= 105°

   5x ÷5 = 105 ÷ 5

   x = 21

C. (4x + 75)°

   4(21) + 75

   84 + 75 = 159°

Hector had 30 minutes to do a three-problem quiz. He spent 11 3 4 minutes on question A and 6 1 2 minutes on question B. How muc
stich3 [128]

Answer:

11 \frac{3}{4} min

Step-by-step explanation:

In order to solve this problem, we must subtract the times he has already used from the time he has available, so we get:

30-11 \frac{3}{4} - 6 \frac{1}{2}

we can start solving this subtraction by turning all of the numbers into improper fractions so we get:

\frac{30}{1}-\frac{11*4+3}{4}- \frac{6*2+1}{2}

\frac{30}{1}-\frac{47}{4}- \frac{13}{2}

next, we can find a least common denominator. In this case it will be 4, so we need to turn all denominators into a 4, so we get:

\frac{30*4}{1*4}-\frac{47}{4}- \frac{13*2}{2*2}

\frac{120}{4}-\frac{47}{4}- \frac{26}{4}

and now we can subtract the numerators and copy the denominators so we get:

\frac{120-47-26}{4}

\frac{47}{4}

which can now be turned into a mixed number by dividing 47/4 which yields 11 with a remainder of 3, so the mixed number is:

11 \frac{3}{4} min

and this is the amount of time he has available to solve the las problem.

A hemispherical tank is filled with water and has a diameter of 15 feet. If water weighs 62.4 pounds per cubic foot, what is the
KATRIN_1 [288]

Answer:

55135 lbs (rounded to the nearest pound)

Step-by-step explanation:

​diameter of tank = 15 ft

Radius = 15/2 =7.5

volume of hemisphere = 2/3 ×π× 7.5³=883.5729

total weight of water = 62.4 × 883.57 = 55134.768

55134.768 rounded to the nearest pound is 55135 lb

a vector has a magnitude of 50 in the 35º direction. what are the horizontal and vertical components of this vector?
Semenov [28]

Answer:

Horizontal component: 40.95

Vertical component: 28.67

Step-by-step explanation:

To find the horizontal and the vertical component of this vector, you need:

The formula for calculate the horizontal component:

a_x=|a|cos\alpha

Where |a| is the magnitude

The formula for calculate the vertical component:

a_y=|a|sin\alpha

Where |a| is the magnitude

Given the angle 35 degrees and the magnitude,you can substitute values into the formulas.

Therefore, you get  that the horizontal component and the vertical component of this vector are:

a_x=50cos(35\°)=40.95

a_y=50sin(35\°)=28.67
