Jada have a monthly budget for her cell phone bill last month she spent 120% of her budget and the bill was $60 what is Jada monthly budget

Answers

Assume that the budget is n.

Now we are given that 120% of the budget is equal to $60.

This means that:

60 = 1.2n

Solve the equation for n to know the budget:

60 = 1.2n

n = 60 / 1.2 = 50

Based on the above calculations, Jada's budget is 50$

Riley rakes 1/6 of a lawn in 2/3 hour. How many lawns can Riley rake per hour?

Answers

Answer:

Riley rakes 1/4 of the lawns per hour.

Step-by-step explanation:

It is given that,

Riley rakes 1/6 of a lawn in 2/3 hour.

We need to find how many lawns can Riley rake per hour.

In 2/3 hour Riley rakes 1/6 of a lawn

In 1 hour Riley rakes [tex]\dfrac{1}{6}\times \dfrac{3}{2}=0.25[/tex] = 1/4 of a lawn.

Hence, Riley rakes 1/4 of the lawns per hour.

So you have 21 people that you want to have meet in groups of 3. How many rounds of meeting would it take to have them all meet?

Answers

Answer:

1330 rounds of meetings

Step-by-step explanation:

You have a total of 21 people, and they all want to meet with each other in groups of 3. This means we are dealing with a combination problem, where combination is the selection of items in which order does not matter.

Formula for combination:

ₙCᵣ = [tex]\frac{n!}{r!(n-r)!}[/tex]

where n is the total number of objects (in this case, total number of people: 21), and r is the sample set (in this case, groups: 3).

We plug in and get:

-> [tex]\frac{21!}{3!(21-3)!}[/tex]

-> 1330 different meetings for everyone to meet with each other in groups of 3.

It is 170 miles from Bruce's house to the city where his brother lives. On his last trip to visit his brother, he drove for 2 hours at 55 miles per
hour. Then he came to some very bad road construction. The rest of the trip took 2 hours. How many miles per hour did Bruce drive for the rest
of the trip?
Va

Answers

Answer:

He drove the rest of the trip at 30 miles per hour

Step-by-step explanation:

The rule of the distance is D = v × t, where

v is the speedt is the time

∵ It is 170 miles from Bruce's house to the city where his brother lives

∴ D = 170 miles

∵ He drove for 2 hours at 55 miles per hour

∴ t1 = 2 hours and v1 = 55 miles/hour

→ By using the rule above find the distance of this part of his trip

∴ D1 = 55 × 2 = 110 miles

∵ The rest of the trip took 2 hours

∴ t2 = 2 hours

∵ D = D1 + D2

→ Substitute the values of D and D1 to find D2

∴ 170 = 110 + D2

→ Subtract 110 from both sides to find D2

∴ 60 = D2

∴ D2 = 170 - 110 = 60 miles

∵ The rest of the trip is 60 miles

∵ It took 2 hours

∵ D2 = v2 × t2

∴ 60 = v2 × 2

→ Divide both sides by 2

∴ 30 = v2

∴ v2 = 30 miles/hour

∴ He drove the rest of the trip at 30 miles per hour

A vector has a horizontal component of 14 and a vertical component of 36. Find the direction angle and the magnitude. Direction angle?

Answers

Answer:

The direction angle is 68.73 degrees and its magnitude is 38.62.

Step-by-step explanation:

Given that,

The horizontal component of a vector = 14

The vertical component of a vector = 36

Let the magnitude of a vector is v. So,

[tex]v=\sqrt{14^2+36^2} \\\\=38.62[/tex]

For direction,

[tex]\tena\theta=\dfrac{y}{x}\\\\=\dfrac{36}{14}\\\\\theta=\tan^{-1}(2.57)\\\\=68.73^{\circ}[/tex]

So, the direction angle is 68.73 degrees and its magnitude is 38.62.

Answer:

sin x = -5/13

csc x = -13/5

sec x = 13/12

cot x = -12/5

tan x = -5/12

Step-by-step explanation:

**x is in quadrant iv because 3pi/2<x<2pi

if cos x=12/13, then 12 is the adjacent value and 13 is the hypotenuse value. to find sin, or opposite/hypotenuse, use the pythagorean identity. opposite=5 and hypotenuse is given as 13. & since it's in quad iv, the sine (or y) value is negative bc it's below the x axis. thus, sin x = -5/13csc is cosecant, or the reciprocal of sine. so csc x = -13/5sec is secant, or the reciprocal of cosine. so sec x = 13/12tan is opp/adj, so tan x = -5/12. it's negative bc tan is negative in quad ivcot is cotangent, or the reciprocal of tangent. so cot x = -12/5

Answer:

8. sin x = -5/13

9. csc x = -13/5

10. sec x = 13/12

11. cot x = -12/5

12. tan x = -5/12

Step-by-step explanation:

The mnemonic SOH CAH TOA can help you with the sine and tangent. You need to rely on your memory (or notes) to find the reciprocal functions.

The dimensions are such that you can recognize this as a 5-12-13 right triangle. Or, you can use the Pythagorean theorem to find the third side from ... O = -√(H² -A²) = -√(169 -144) = -√25 = -5

The given quadrant tells you that O is negative.

8. Sin = Opposite/Hypotenuse

Here, the opposite is -5. The hypotenuse is always taken to be positive.

sin x = -5/13

9. Csc = 1/Sin

csc x = -13/5

10. Sec = 1/Cos

sec x = 13/12

11. Cot = 1/Tan = Adjacent/Opposite

cot x = 12/-5

cot x = -12/5

12. Tan = Opposite/Adjacent

tan x = -5/12

Susan has a piggy bank with 28 coins in it, all dimes and quarters. She has been collecting state quarters and so far has no repeats. If the piggy bank has $5.50. how many more quarters does Susan need before she has a quarter from each of the 50 states?
HELP I WILL GIVE POINTS AND BRAINLIEST

Answers

Answer:

She needs 32 quarters.

Step-by-step explanation:

d = dime q = quarters

d + q = 28 so d = 28-q

0.1d + 0.25q = 5.50

0.10 * (28-q) + 0.25q = 5.50

2.80 - 0.10q + 0.25q = 5.50

0.15q = 5.50 - 2.80

0.15q = 2.70

q = 2.70 / 0.15

q = 18 quarters (she has)

50-18= 32 quarters (she needs)

A ball is shot upward such that its height (in feet) above the ground after t seconds is h(t) = -16t2 + 96t + 5. What is the ball's maximum height?

Answers

Answer:

149 feet

Step-by-step explanation:

you have a quadratic equation and you need to fid it's vertex because that is the max height

h(t)= -16t² +96t +5

the x coordinate of the vertex is x= -b/2a for f(x)= ax²+bx+c so in our case

x= [tex]\frac{-96}{2*(-16)}[/tex]= 3 , now we know that the vertex bbelongs to the graph so should verify the equation so we substitute t of the value of x=3 to find y

y= -16*3²+96*3+5= -144+288+5=149

the max height is the coordinate of y because it tels us how much it went up
