help my lil cousin with her work

Since the shape is a parallelogram, there are 2 pairs of opposite but equal sides --> "6a+21" and "20a+7"                   "11a" and "4a+7"

The easier pair is

11a = 4a+7              Subject 4a from both sides

7a = 7                     Divide 7 from both sides

a = 1

A = 1

Answer:

Mrs. Foster's class had the most students in class that Friday

Step-by-step explanation:

Mr Lopez - 92.5%

Mrs Foster - 19/20

Mr Kelly - 0.9

Let's say that there were 40 students in class

92.5% of 40 would be 37

So

Mr Lopez's Class had 37 students.

19/20 of 40 would be 38

So

Mrs Foster's Class had 38 students

0.9 of 40 would be 36

So

Ms Kelly's class had 36 students

Therefore, from looking at this, the answer would be Mrs Foster's Class

Answer:

4(7 + 6)

Step-by-step explanation:

The GCF (greatest common factor) is the largest factor that both numbers share, and in this case it is 4.

28+24 as a  product of 2 factors using the GCF and the distributive property is 4(7+6)

A number system is defined as a system of writing to express numbers.

We need to write  28 + 24 as a product of 2 factors using the GCF and the distributive property.

A factor is a number that divides another number, leaving no remainder

The greatest common divisor of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers.

We need to find factors 28 and 24

28=1,2,4,7,14,28

24=1,2,3,4,6,8,12,24

4 is the greatest common factor.

28 + 24

Take 4 as common

4(7+6)

Hence, 28+24 as a  product of 2 factors using the GCF and the distributive property is 4(7+6)

Just divide $45.00 and 36

The correct answer is OA. It is the graph of f(x) translated 11 units to the right.

The transformation g(x) = f(x - 11) represents a horizontal translation of the graph of f(x) = x.

When we substitute x - 11 into the function f(x), it shifts the entire graph 11 units to the right.

This is because for every value of x in f(x), we are now evaluating f(x - 11), which means the x-values are shifted to the right by 11 units.

Therefore, the correct statement is that g(x) is the graph of f(x) translated 11 units to the right.

We can name the sides of a right triangle by finding their location given one of the angles.

The sine, cosine, and tangent ratios are the three basic trigonometric ratios:

The given angle in this case ([tex]\theta[/tex]) is the angle that measures 15°.

We're also given the side adjacent to it (that is not the hypotenuse), which measures 300 units.

And finally, we're asked to solve for the side opposite the given angle.

The ratio that involves solving using the opposite and the adjacent sides is the tangent ratio. Plug in all the given values:

[tex]\tan\theta =\dfrac{opposite}{adjacent}\\\\\tan(15^\circ)=\dfrac{x}{300}[/tex]

Isolate x by multiplying both sides by 300:

[tex]300\tan(15^\circ)=x\\\\300\tan(15^\circ)=80.4[/tex]

Therefore, x = 80.4 when rounded to the nearest tenth.

x = 80.4

Answer:

76

Step-by-step explanation:

Given a quadratic equation in standard form

ax² + bx + c = 0 ( a ≠ 0 ) , then the discriminant is

Δ = b² - 4ac

Given

3x² - 10x = - 2 ( add 2 to both sides )

3x² - 10x + 2 = 0 ← in standard form

with a = 3, b = - 10, c = 2 , then

b² - 4ac = (- 10)² - (4 × 3 × 2 ) = 100 - 24 = 76

Answer:

0.7333

Step-by-step explanation:

2021 Math

Proportion of such tomatoes have a diameter between 20 and 26 mm is 0.7333.

It's a way to measure how far each data point is spread from the average value.

let x represents the diameters of cherry tomatoes produced by large farm which is formally distributed with mean = 22m

and, standard deviation= 2.5 mm

Now, proportion of tomatoes have diameter between 20 and 26 mm

=P (20 < x< 26)

=P(20-22 / 2.5 < [tex]x- \mu/ \sigma[/tex] < 26- 22/2.5)

=P(-0.8 < z < 1.6)

=P(z = 1.6) - P(z=-0.8)

=0.9452 - 0.2119

==0.7333

Hence, proportion of such tomatoes have a diameter between 20 and 26 mm is 0.7333.
