siniylev [52]

Answer:

$p = .22 = 22 \: \: percent \: increase$

Step-by-step explanation:

$166(1 + p) = 202.52$

$1 + p = \frac{202.52}{166}$

$p = \frac{202.52}{166} - 1$

Help cause I haven’t been paying attention in class hehehe

Answer:

1) g ≥ 17

2) g > -10

3) g > -1

Step-by-step explanation:

1) 7 (g-19) ≥ -14 divide both sides by 7

g - 19 ≥ -2 add 19 to both sides

∴ g ≥ 17

=======================================

2) 3(7g+17) > -19 + 14g

21g + 51 > -19 + 14g

21g - 14g> -19 - 51

7g > -70

g > -10

========================================

6(-6g+6) > -2(19g-17)

-36g + 36 > -38g + 34

-36g + 38g > 34 - 36

2g > -2

g > -1

========================================

An acute ∆ABC is rotated about a point and then dilated by a scale factor of 0.5 to produce ∆A’B’C’. Which statement correctly c

icang [17]

Answer:

Option given in the top right.

Step-by-step explanation:

If an acute triangle is rotated about a point,

- Angles of the transformed triangle remain unchanged.

If a triangle is dilated by a scale factor of $\frac{1}{2}$ ,

- Measure of sides of the image will be dilated by a scale factor of 0.5.

Therefore, statement that compares ΔABC to ΔA'B'C' will be,

The angle measures of the triangle A'B'C'are the same of those ΔABC, but the side length of the ΔA'B'C' half the size of those of ΔABC.

Option given in the top right is the answer.

A species of phytoplankton measures about 2 × 10−6 in. A grain of sand measures about 1 × 10−4 in. About how many times longer i

taurus [48]

Answer : The grain of sand is 50 times greater than the phytoplankton.

Step-by-step explanation :

As we are given that:

Size of phytoplankton = 2 × 10⁻⁶ in

Size of sand grain = 1 × 10⁻⁴ in

Now we have to determine how many times longer the grain of sand is than the phytoplankton.

We are dividing the sand grain size by the phytoplankton size.

This can be done by equating it as follows:

$\frac{\text{Size of sand grain}}{\text{Size of phytoplankton}}=\frac{1\times 10^{-4}in}{2\times 10^{-6}in}$

$\frac{\text{Size of sand grain}}{\text{Size of phytoplankton}}=50$

Therefore, the grain of sand is 50 times greater than the phytoplankton.

If 75% of the students in a middle school ride the bus home, and that is 225 students, how many students are there in the middle

BartSMP [9]

Hello! I think that 300 students attend that middle school. Since 225 is 75% of the students all I did was make 75% a fraction, which is 3/4. Then, I figured out that 225/300 is equivalent to 3/4 or 75%.
