Answer:

$- 60a ^{6}$

Step-by-step explanation:

1) Take out the constants.

$(10 \times - 6) {a}^{2} {a}^{4}$

2) Simplify 10 × -6 to -60.

${ - 60a}^{2} {a}^{4}$

3) Use product rule.

$- 60 {a}^{2 + 4}$

4) Simplify 2 + 4 to 6.

$- 60 {a}^{6}$

Therefor, the answer is -60a⁶.

Rhys will tile the rectangle below to find it’s area. Q: How many unit squares with side length 1/10 foot will Rhys use to tile

Inessa [10]

The number of unit squares with a side length of 1/10 foot that Rhys uses to tile the rectangle is 24 units

<h3>How to calculate the area of plane shapes?</h3>

A square is a plane shape with 4 sides

The formula for calculating the area of the square is expressed as:

A = l^2

Given

side length of a square = 1/10 foot

A = (1/10)² = 1/100 = 0.01 square foot

Determine the area of the rectangle

Area = length * width

Area = 3/10 * 4/5
Area = 12/50 = 6/25
Area = 0.24 square foot

Take the ratio of both areas

Ratio = 0.24/0.01

Ratio = 24 units

Hence the number of unit squares with a side length of 1/10 foot that Rhys uses to tile the rectangle is 24 units

1. Ms. G says that a solution to the equation 2x - 6 = 7x must also be a solution to the equation 5x-6=10x

timama [110]

Answer:

Well......

Step-by-step explanation:

Well if you subtract 2x from 7x, you get 5x. If you subtract 5x from 10x, you get 5x. When you Do that to both formulas, you end up with the same formula: 5x=-6.

The weights of 6-week-old poults (juvenile turkeys) are normally distributed with a mean 8.9 pounds and standard deviation 1.9 p

andre [41]

Answer:

$z=-2.33$

And if we solve for a we got

$a=8.9 -2.33*1.9=4.47$

And the best answer for this case would be:

A) 4.47 lb

Step-by-step explanation:

Let X the random variable that represent the weights of juvenile turkeys, and for this case we know the distribution for X is given by:

$X \sim N(8.9,1.9)$

Where $\mu=8.9$ and $\sigma=1.9$

The z score formula very useful for this case is given by:

$z=\frac{x-\mu}{\sigma}$

For this part we want to find a value a, such that we satisfy this condition:

$P(X>a)=0.99$ (a)

$P(X$ (b)

Both conditions are equivalent on this case. We can use the z score again in order to find the value a.

As we can see on the figure attached the z value that satisfy the condition with 0.01 of the area on the left and 0.99 of the area on the right it's z=-2.33. On this case P(Z<-2.33)=0.01 and P(z>-2.33)=0.99

If we use condition (b) from previous we have this:

$P(X$
