Answer:

$\huge\boxed{Area\ of\ Rectangle = 10x\³}$

Step-by-step explanation:

Area of Rectangle = Length * Width

Where Length = 2x and Width = 5x²

Area of Rectangle = (2x)(5x²)

Area of Rectangle = 10x³

Answer:

$\boxed{\sf Area \ of \ rectangle = 10x^3}$

Given:

Length of rectangle = 5x²

Width of rectangle = 2x

To Find:

Area of rectangle

Step-by-step explanation:

$\sf Area \ of \ rectangle = Length \times Width$

$\sf = 5 {x}^{2} \times 2x$

$\sf = 5 \times 2 {x}^{2 + 1}$

$\sf = 5 \times 2 {x}^{3}$

$\sf = 10 {x}^{3}$

Given,

A linear function consisting of 2 terms, one is dependent on time and the other one is independent of time, i.e.,

A = -2.3t - 7

The dependent term -2.3 indicates that the altitude of Mr Mole decreases by 2.3 meters every minute.

At t = 0, A = -2.3(0) - 7 = 0 - 7 = -7. (Negative sign indicates the value is below the ground level of 0 meter.

The constant term - 7 is the altitude at t = 0, because at t = 0

Thus, Mr. Mole's burrow lie 7 meters below the ground.

Need help with this question 2 + (4h- 1) = 13h Need All Steps Plz

vredina [299]

Answer and Step-by-step explanation:

For this equation, we are solving for h.

We are given the equation:

2 + 4h - 1 = 13h

First, we need to Simplify the equation.

2 - 1 + 4h = 13h

1 + 4h = 13h

Now, we need to Subtract 4h from both sides of the equation.

1 + 4h - 4h = 13h - 4h

1 = 9h

Finally, we Divide both sides by 9 to get h.

$\frac{1}{9} = h$

h is equal to $\frac{1}{9}$ .

To check your answer, we plug $\frac{1}{9}$ back into the given equation.

$2 + 4(\frac{1}{9} ) - 1 = 13(\frac{1}{9} )\\\\\\\\2 + \frac{4}{9} -1 = \frac{13}{9} \\\\\\1 = \frac{9}{9} \\\\1 = 1$

I hope this helps!

mr lim gave $1200 to his mother. he then spent 3/5 of his remaining money on a computer. in the end he had 1/5 of his original a

Harlamova29_29 [7]

Let the original amount be x so ,
according to question,
3x/5 + 1x/5 + 1200 = x
or, 1200 = x - 4x/5
or, 1200 = 1x/5
or, x = 6000

In a process that manufactures bearings, 90% of the bearings meet a thickness specification. A shipment contains 500 bearings. A

Marina86 [1]

Answer:

(a) 0.94

(b) 0.20

Step-by-step explanation:

From a population (Bernoulli population), 90% of the bearings meet a thickness specification, let $p_1$ be the probability that a bearing meets the specification.

So, $p_1=0.9$

Sample size, $n_1=500$ , is large.

Let X represent the number of acceptable bearing.

Convert this to a normal distribution,

Mean: $\mu_1=n_1p_1=500\times0.9=450$

Variance: $\sigma_1^2=n_1p_1(1-p_1)=500\times0.9\times0.1=45$

$\Rightarrow \sigma_1 =\sqrt{45}=6.71$

(a) A shipment is acceptable if at least 440 of the 500 bearings meet the specification.

So, $X\geq 440.$

Here, 440 is included, so, by using the continuity correction, take x=439.5 to compute z score for the normal distribution.

$z=\frac{x-\mu}{\sigma}=\frac{339.5-450}{6.71}=-1.56$ .

So, the probability that a given shipment is acceptable is

$P(z\geq-1.56)=\int_{-1.56}^{\infty}\frac{1}{\sqrt{2\pi}}e^{\frac{-z^2}{2}}=0.94062$

Hence, the probability that a given shipment is acceptable is 0.94.

(b) We have the probability of acceptability of one shipment 0.94, which is same for each shipment, so here the number of shipments is a Binomial population.

Denote the probability od acceptance of a shipment by $p_2$ .
