Answer:

$133

Step-by-step explanation:

Let x = amount of money she had before she spent any money.

x - 29 - 29 - 29 - 15 = 31

x - 102 = 31

x = 133

Answer: She had $133.

What is interest earned on 3500 invested at 6% compounded quarterly or 12 years

enyata [817]

$\bf \qquad \textit{Compound Interest Earned Amount}
\\\\
A=P\left(1+\frac{r}{n}\right)^{nt}
\quad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to &\$3500\\
r=rate\to 6\%\to \frac{6}{100}\to &0.06\\
n=
\begin{array}{llll}
\textit{times it compounds per year}\\
\textit{quarterly, thus four}
\end{array}\to &4\\
t=years\to &12
\end{cases}
\\\\\\
A=3500\left(1+\frac{0.06}{4}\right)^{4\cdot 12}\implies A=3500(1.015)^{48}$

so, the interest earned then will be A - 3500.

Write an equation to find x, then solve for angle measure A. 25 points.

prohojiy [21]

Answer:

Step-by-step explanation:

23). By applying triangle sum theorem in the given triangle,

(x + 83)° + (x + 48)° + 65° = 180°

2x + 196 = 180

2x = -16

x = -8

Measure of angle A = x + 48

= -8 + 48

= 40°

Therefore, Option A is the answer.

24). By triangle sum theorem,

(3x + 14)° + 90° + (4 + 3x)° = 180°

6x + 108 = 180

6x = 72

x = 12

Measure of angle A = (4 + 3x)

= 4 + 3(12)

= 40°

Therefore, Option A is the answer.

The table below shows the distance d(t) in meters that an object travels in t seconds: t (seconds) d(t) (meters) 3 126 4 224 5 3

Rasek [7]

(d(5) -d(3))/(5 -3) = (350 -126)/2 = 112 . . . . . meters/second

112 m/s; it represents the average speed of the object between 3 seconds and 5 seconds

Select all the situations that can be represented by 1/2⋅5. * 1 point Diego lives 5 miles from school, and Elena lives 1/2 as fa

SpyIntel [72]

Answer:

Elena lives 2.5 miles away from school.
The total liters of water is 2.5 liters
He can cut 10 pieces of rope of length 1/2 meter
The fraction of her goal she ran is 1/10

Step-by-step explanation:

From the question,

Diego lives 5 miles from school, and Elena lives 1/2 as far away as Diego

Therefore, Elena lives 1/2 of 5 miles away from school.

1/2 of 5 miles = 2.5 miles

Hence, Elena lives 2.5 miles away from school.

Jada has 5 bottles that each contain 1/2 liter of water.

Since each bottle contain 1/2 liter of water, then

The total liters of water is (1/2 × 5) liters

1/2 × 5 = 2.5 liters

Hence, the total liters of water is 2.5 liters

Noah has 5 meters of rope

To determine how many pieces of rope of length 1/2 meter he can cut,

Number of pieces of rope of length 1/2 meter that can be cut is 5 meter ÷ 1/2 meter

5 meter ÷ 1/2 meter = 10

Hence, he can cut 10 pieces of rope of length 1/2 meter.

Lin's goal is to run 5 miles. She ran 1/2 mile.

To determine what fraction of her goal that is,

First, she ran 1/2 mile out of 5 miles.

The fraction of her goal she ran is 1/2 mile ÷ 5 miles

1/2 mile ÷ 5 miles = 1/10

Hence, the fraction of her goal she ran is 1/10.
