Is (a-1)(b+2) a factorization of an-b+2a+2?

Answer:

the scale factor is 4 as from the table

So the different number has a 4 with a value of 40.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

To solve this problem, we need to first identify the place value of the digit 4 in the given number.

The digit 4 is in the hundreds place in the number 431.67, so its value is 4 x 100 = 400.

According to the problem statement, the 4 in the different number represents a value which is one-tenth of the value of the 4 in 431.67. Therefore, the value of the 4 in the different number is:

400/10 = 40

To determine the value of the different number, we need to look at the other digits in the number. Since we don't have any information about the other digits, we cannot determine the value of the different number. The answer is that the value of the different number cannot be determined with the information given.

Therefore, So the different number has a 4 with a value of 40.

Answer:

0.0809

Step-by-step explanation:

Given that :

Mean(m) = 16000

Standard deviation (s) = 1500

Probability that the life span of the monitor will be more than 18,099

P(x > 18099)

Using the Zscore formula :

Zscore =(x - m) / s

Zscore = (18099 - 16000) / 1500

Zscore = 2099 / 1500

Zscore = 1.399

P(Z > 1.399)

Using the Z probability calculator :

P(Z > 1.399) = 0.080906

= 0.0809

Answer:

Step-by-step explanation:

There are two ways you can divide 2/3 by 1/6.

1) Division by a number is the same as multiplication by its reciprocal. The reciprocal of a fraction is the fraction obtained by swapping the numerator and denominator. So, division by 1/6 is the same as multiplication by 6/1.

  2/3 ÷ 1/6 = 2/3 × 6/1

The result of this multiplication is the product of the numerators divided by the product of the denominators:

  2/3 × 6/1 = (2×6)/(3×1) = 12/3 = 4

__

2) The fractions can be expressed with the same denominator. Then their quotient is the quotient of their numerators.

  2/3 = 4/6

  2/3 ÷ 1/6 = 4/6 ÷ 1/6 = 4 ÷ 1 = 4

area of pizza is 50.24 ft²

Answer:

Ms. Long ordered a pizza with area 50.24 ft².

Step-by-step explanation:

Here, we have given that the radius of circular pizza is 4 ft.

So, finding the area of circular pizza by substituting the values in the formula :

\(\longrightarrow{\pmb{\sf{Area_{(Circle)} = \pi{r}^{2}}}}\)

\(\longrightarrow{\sf{Area_{(Pizza)} = 3.14{(4)}^{2}}}\)

\(\longrightarrow{\sf{Area_{(Pizza)} = \dfrac{314}{100} \times {(4 \times 4)}}}\)

\(\longrightarrow{\sf{Area_{(Pizza)} = \dfrac{314}{100} \times (16)}}\)

\(\longrightarrow{\sf{Area_{(Pizza)} = \dfrac{314}{100} \times 16}}\)

\(\longrightarrow{\sf{Area_{(Pizza)} = \dfrac{314 \times 16}{100}}}\)

\(\longrightarrow{\sf{Area_{(Pizza)} = \dfrac{5024}{100}}}\)

\(\longrightarrow{\sf{Area_{(Pizza)} = 50.24 }}\)

\(\star{\underline{\boxed{\sf{\purple{Area_{(Pizza)} = 50.24 \: {ft}^{2}}}}}}\)

Hence, the area of pizza is 50.24 ft².

The completed statements with regards to the lengths of the midsegments of the triangle ΔABC is presented as follows;

Because the slopes of \(\overline{DE}\) and \(\overline{CB}\) are both 1, \(\overline{DE}\) ║ \(\overline{CB}\). DE = 2·√2 and CB = 4·√2. Because 2·√2 = (1/2)·4·√2, DE = (1/2)·CB

The midsegment theorem states that the segment that joins the midpoints of two sides of a triangle is parallel to the third side and is half the length of the third side.

The coordinates of the vertices of the triangle ΔABC are;

A(-5, 2), B(1, -2), C(-3, -6)

The coordinates of the midpoints of the triangle are; E(-2, 0), D(-4, -2), F(-1, -4)

\(\overline{DE}\), \(\overline{DE}\), and \(\overline{DE}\) are the midsegments, of the triangle ΔABC

The midsegment theorem indicates;

DE = (1/2)×CB

EF = (1/2)× AC

DF = (1/2)×AB

The slope of the midsegment \(\overline{DE}\) = (0 - (-2))/(-2 - (-4)) = 1

The slope of the midsegment \(\overline{CB}\) = (-2 - (-6))/(1 - (-3)) = 1

The slope of \(\overline{DE}\) and \(\overline{CB}\) are both 1, therefore,  \(\overline{DE}\) and \(\overline{CB}\) are parallel;

\(\overline{DE}\) ║ \(\overline{CB}\)

The length of segment  DE = √((-4 - (-2))² + (-2 - 0)²) = 2·√2

The length of segment  CB = √((1 - (-3))² + (-2 - (-6))²) = 4·√2

2·√2 = (1/2) × (4·√2)

Therefore; DE = (1/2) × CB

Answer:

x=135

Step-by-step explanation:

The two angles are supplementary, meaning they both add up to 180°.

So to find the value of one angle, simply subtract 50 from 180.

180-50=130

So now we know that 130 is equal to the expression.

x-5=130

Add 5 to both sides.

x=135

Answer:

318

Step-by-step explanation:

Standard form explanation:

So you would set your equation up, 3 is the divisor which should stay outside, the 954 is the dividend which stays inside. Then we do 9 divided by 3 which is 3, so you need to write 3 on top of the quotient and has to be aligned with the 9 (the hundred's place value). After we done 9/3, under the 9 we need to subtract the 9. That should equal 0. After that the 5 in the ten's place in 954 goes down, you should have 05, we then would need a number that goes into 5 without going over. That number would be 1 because if you did 2 you would go over. So, write 1 in the quotient aligning with the 5. Do 3 x 1 = 3, after that write a 3 underneath the 5. Then do 5-3 = 2. Carry the 4 down, you have 24 as the number. Then you need a number that goes into 24 evenly, which is 8. Same steps as last, then do 24-24= 0, after you get 0. You stop and circle the quotient which is 318 in standard form/algorithm.

Based on the data recorded by Anna on Saturday, we can estimate the number of people expected to visit The Youth Wing on Sunday.

Let's calculate the proportion of visitors to The Youth Wing compared to the total number of visitors on Saturday:

\(\displaystyle \text{Proportion} = \frac{\text{Visitors to The Youth Wing on Saturday}}{\text{Total visitors on Saturday}} = \frac{382}{382 + 461 + 355}\)

Next, we'll apply this proportion to the total number of visitors on Sunday to estimate the number of people expected to go to The Youth Wing:

\(\displaystyle \text{Expected visitors to The Youth Wing on Sunday} = \text{Proportion} \times \text{Total visitors on Sunday}\)

Now, let's substitute the values into the equation and calculate the estimated number of visitors to The Youth Wing on Sunday:

\(\displaystyle \text{Proportion} = \frac{382}{382 + 461 + 355}\)

\(\displaystyle \text{Expected visitors to The Youth Wing on Sunday} = \text{Proportion} \times 800\)

Calculating the proportion:

\(\displaystyle \text{Proportion} = \frac{382}{382 + 461 + 355} = \frac{382}{1198}\)

Calculating the estimated number of visitors to The Youth Wing on Sunday:

\(\displaystyle \text{Expected visitors to The Youth Wing on Sunday} = \frac{382}{1198} \times 800\)

Simplifying the equation:

\(\displaystyle \text{Expected visitors to The Youth Wing on Sunday} \approx \frac{382 \times 800}{1198}\)

Now, let's calculate the approximate number of visitors to The Youth Wing on Sunday:

\(\displaystyle \text{Expected visitors to The Youth Wing on Sunday} \approx 254\)

Therefore, based on the data recorded on Saturday, we can estimate that around 254 people should be expected to go to The Youth Wing on Sunday.

Answer:

sin(100°) = 0.985

sin(-100°) = -0.985

Step-by-step explanation:

In a unit circle, each point (x, y) on the circumference corresponds to the coordinates (cos θ, sin θ), where θ represents the angle formed between the positive x-axis and the line segment connecting the origin to the point (x, y).

Therefore, sin(100°) equals the y-coordinate of the point (-0.174, 0.985), so:

\(\boxed{\sin(100^{\circ}) = 0.985}\)

Similarly, sin(-100°) equals the y-coordinate of the point (-0.174, -0.985), so:

\(\boxed{\sin(-100^{\circ}) = -0.985}\)

In the unit circle the value of sin (100) = 0.985 and the value of sin (-100) = -0.985, in three decimal places.

The value of the sine of the angles is calculated by applying the following formula as follows;

The value of sin (100) is calculated as follows;

sin(100°) corresponds to the y-coordinate of the point (-0.174, 0.985) as given on the coordinates of the unit circle.

sin (100) = 0.985

The value of sin (-100) is calculated as follows;

sin(100°) corresponds to the y-coordinate of the point (-0.174, -0.985), as given on the coordinates of the circle.

sin (-100) = -0.985

Thus, in the unit circle the value of sin (100) = 0.985 and the value of sin (-100) = -0.985, in three decimal places.
