Answer:

groups of 6 students.

Step-by-step explanation:

Mr. Ramirez has 18 sixth grade students and 24 seventh grade students.

He wants to put the students in equal group of only one grade students.

So we calculate the HCF of the numbers.

18 = 2 × 3 × 3

24 = 2 × 2 × 2 × 3

= 2 × 3

HCF = 6

Hence there would be 6 students group for each grade

6th grade = 6 + 6 + 6  = 18 students

7th grade = 6 + 6 + 6 + 6  = 24 students

Total 7 groups of 6 students would be made.

Shape 1 and shape 2 are plotted on a coordinate plane. Which statement about the shapes is true?
kiruha [24]
Each square unit is one unit. Each triangle is half a unit.

Shape 1 has 6 units and 4 half units.
6 + 4/2 =
6 + 2 =8
Shape 1 has 8 units.

Shape 2 is almost like shape 1 but it has an extra bit which would make it larger than shape 1.

So shape 2 is larger than shape 1.

An octopus weighted 5/6 kilogram. After two weeks, it's weight has increased by 3/10 kilogram. But afterwards, it lost 1/5 kilog
Alex777 [14]

Answer

14/15 kg

Step-by-step explanation:

Rewriting our equation with parts separated

=1+215−15

Solving the fraction parts

2/15−15=?

Find the LCD of 2/15 and 1/5 and rewrite to solve with the equivalent fractions.

LCD = 15

2/15−3/15=−1/15

Combining the whole and fraction parts

1−1/15=14/15

Solution by Formulas

converting mixed numbers to fractions, our initial equation becomes,

17/15−15

Applying the fractions formula for subtraction,

=(17×5)−(1×15)15×5

=85−15/75

=70/75

Simplifying 70/75, the answer is

=14/15

The region bounded by the given curves is rotated about the specified axis. Find the volume V of the resulting solid by any meth
Julli [10]

Answer:

V  = 23π/6

Step-by-step explanation:

V = 2π ∫ [a to b] (r * h) dx

y = −x² + 23x − 132

y = −(x² − 23x + 132)

y = −(x − 11) (x − 12)

Parabola intersects x-axis (line y = 0) at x = 11 and x = 12 ----> a = 11, b = 12

r = x

h = −x² + 23x − 132

V = 2π ∫ [11 to 12] x (−x² + 23x − 132) dx

V  = 23π/6

Melissa owns a credit card with a 8.9% APR that calculates interest using the ADB excluding new purchases method. The balance af
ira [324]

Answer:

$4.081

Step-by-step explanation:

We have been given that Melissa owns a credit card with a 8.9% APR. The balance after her last billing cycle was $550.      

First of all, we will find period rate by dividing APR by 12 as 1 years equals 12 months.

\text{Period rate}=\frac{8.9\%}{12}=0.74166\%

The finance charge would be 0.74166% of $550.

\text{The finance charge}=\$550\times \frac{0.742}{100}

\text{The finance charge}=\$550\times 0.00742

\text{The finance charge}=\$4.081

Therefore, the finance charge would be $4.081.
