So it started at 180. After 4 more years it’s grown 188 cm to 368. If we estimate that it’ll grow 188 cm in another 4 years that puts our total to around 556. If we estimate and take off a year, it would probably be around 548 cm :)

Pls helpppppp for brainly

Varvara68 [4.7K]

Answer:

$\frac{6}{8}$ or $\frac{3}{4}$

Step-by-step explanation:

Convert the mixed numbers into improper fractions.

$2\frac{3}{8}-1\frac{5}{8}=\frac{19}{8}-\frac{13}{8}$

Since the two fractions have the same denominator, just subtract the numerators.

$\frac{19}{8}-\frac{13}{8}=\frac{6}{8}$

If required, rewrite the fraction in simplest form.

$\frac{6}{8}=\frac{3}{4}$

Find the area of each figure below

Ugo [173]

Answer:

25. $27a^{3}b^{2}$

26. $3\pi x^{3}y$

Step-by-step explanation:

For 25:

$A = \frac{a+b}{2} h$ (area of a trapezoid)

$A=\frac{11a^{2}b+7a^{2}b}{2} *3ab$ (substitute terms)

$= \frac{18a^{2}b}{2}*3ab$ (collect like terms)

$= 9a^{2}b*3ab$ (reduce the fraction by crossing out 2)

$= 27a^{3}b^{2}$ (calculate)

For 26:

$A=\pi r^{2}$ (equation of area of a circle)

$A=\pi (3x^{3} y)^{2}$ (enter the radius)

$= 3\pi x^{3} y$ (communtative property to reorder the terms)
