Answer:

B

Step-by-step explanation:

P = $ 2000

r =5% = 0.05

t = 7 years

Amount=P*(1+\frac{r}{100}})^{t}\\\\=2000*(1+0.05)^{7}\\\\=2000*(1.05)^{7}\\\\=2000*1.4071\\\\

= $ 2814.20

A rectangular photograph is nine centimeters wide and fourteen centimeters long. The photograph is enlarged by increasing the le
koban [17]

Answer:

Width=13cm

Length=18cm

Step-by-step explanation:

Width of the Initial Photograph=9cm

Length of the Initial Photograph=14cm

If width and length are increased by an equal amount, say x

New Width=9+x

New Length=14+x

Area of the new photo is 108 square centimeters greater than the area of the original photo.

Area of Original Photo=14*9=126cm²

Aeea of the New Photo=126+108=234cm²

Therefore:

(9+x)(14+x)=234

126+9x+14x+x²-234=0

x²+23x-108=0

x²+27x-4x-108=0

x(x+27)-4(x+27)=0

(x+27)(x-4)=0

x+27=0 or x-4=0

x=-27 or x=4

Since x≠-27

x=4cm

The dimensions of the new photo are:

Width=9+x=9+4=13cm

Length=14+x=14+4=18cm

Will pick BRAINLIEST!!

Hi there!
The question sounds really complex, but the mathematical operations behind it is figuratively simple. Here, we are told to find 19 (18.7 rounded up is 19) percent of 1,000. To do this, we can set up a proportion to model the whole scenario.
\frac{x}{1000} = \frac{19}{100}
Now, just solve for x by cross multiplying and simplifying.
\frac{x}{1000} = \frac{19}{100}

100x = 19000
x=190
Therefore, 190 people out of 1,000 people leave out pertinent information on their IRS forms. Hope this helped and have a terrific day!

A right triangle is given with a missing value of t. It is stated that the triangle is an acute right triangle with angles 50∘ a
sergiy2304 [10]

Answer: t=20°


Step-by-step explanation:

1. By definition, the sum of the interior angles is 180 degrees.

2. Keeping the information above on mind, you can write the following expression:

90+50+2t=180

3. Now, you must solve for t as following:

140+2t=180\\2t=180-140\\2t=40\\t=\frac{40}{2}\\t=20

4. Therefore, the value of t is 20°
