Sorry, I don't know how to solve this equation.
Please visit the examples page to see what the calculator currently supports.
the correct question Part 1) is
<span>A school photo has dimensions of 2 1/4 inches by 2 3/4 inches. What are the dimensions of the school photo if it is enlarged by a scale factor of 7?
we know that
2 1/4 in-------> (2*4+1)/4----> 9/4 in
2 3/4 in-----> (2*4+3)/4-----> 11/4 in
if the scale factor=7
the dimensions of the school photo are
(9/4)*7-----> 63/4 in-----> 15 3/4 in
(11/4)*7----> 77/4 in-----> 19 1/4 in
the answer Part 1) is
</span>the dimensions of the school photo are
15 3/4 in x 19 1/4 in
Part 2) <span>Stephanie drew a picture of her house with her prize rosebush in the front. In her picture, she drew the rosebush 1.5 centimeters tall, and she drew the house 7.5 centimeters tall.
If her rosebush is really 0.75 meter tall and she made her drawing to scale, what scale did she use?
scale factor=measure in the drawing/measure in the actual
scale factor=1.5 cm/0.75 m-----> 2 cm/m
that means
2 cm in the drawing is equal to 1 meter in the actual
if the house in the drawing is 7.5 cm tall
the house in the actual is 7.5/2----> 3.75 m
the answer Part 2) is
the scale is 2 cm/meters
Part 3)</span><span>A photo of a painting has a scale of 3 inches = 2 feet. If the photo is 7.5 inches long, how many feet long is the painting?
we know that
</span>
scale factor=measure in the photo/measure in the painting
measure in the painting=measure in the photo/scale factor
scale factor=3/2---> 1.5 in/ft
measure in the photo=7.5 in
measure in the painting=7.5/1.5----> 5 ft
the answer part 3) is
the painting is 5 ft long

➷Yes.
Explain: This is because if you feel normal, you might have a little bit of willpower to do something, which will effect the statistical outcome. if you are confident, you will have a higher statistical outcome. (Example: A sport game. Feeling: Normal, Confident, Random) If you feel random, you could get a really bad score or a really high score, but you don't know because it is random.

DOGE
Df/dy=(1350-750)/(2010-2000)
df/dy=60
f(y)=750+60(y-2000) or neatened up a bit...
f(y)=60y-119250 (note: y is the actual year, ie 2005, not year like 2 years from start)
Answer:
Step-by-step explanThis polynomial has three terms. The first one is 4x2, the second is 6x, and the third is 5. The exponent of the first term is 2. The exponent of the second term is 1
