2) x2 + 14x + 48 = 0

Answer: 6625 sqaure yards

Step-by-step explanation:

Area for a trapezoid formula is A=(base 1 + base 2)·height÷2

So base one is 120 and base two is 10+120+15=145

and the height is 50 so (120+145)·50÷2=6625 The area for the trapezoid is 6625

Answer:

-2.03, 2.03

Step-by-step explanation:

The degree of freedom (df) ;

Df total for the two samples = 35

Therefore, obtuaking the critical value using a T-test distribution at 95% confidence level.

(1 - 95%) / 2 = (1 - 0.95) / 2 = 0.05 / 2 = 0.025

Using a T critical value calculator or t table distribution ;

Tcritical, 0.025, df = 35 = 2.03

Left tail = - 2.03

Right = 2.03

Hence, critical cutoff :

(-2.03 ; 2.03)

Answer:

Mr.Nolan paid $193.65 in total for the shirts

Step-by-step explanation:

$36.95 (how much one adult shirt costs) x 2 shirts = $73.90

$23.95 (how much one youth shirt costs) x 5 shirts = $119.75

$119.75 (youth shirts total costs) + $73.90 (adult shirts total cost) = $193.65

Mr.Nolan paid $193.65 for the 2 adult shirts and 5 youth shirts.

Step-by-step explanation:

The compounded amount after 10 years would be $1,458,293.87.

The formula to calculate the compound interest is -

[tex]$A =P(1 + \frac{r}{n}) ^{nt}[/tex]

Given is that Phillip decides to invest $800,000 in a period annuity that earns 5.2% APR compounded monthly for a period of 20 years.

We can calculate the compounded amount as -

A = 800000(1 + 0.052/12)^(12 x 20)

A = 1,458,293.87

Therefore, the compounded amount after 10 years would be $1,458,293.87.

Answer:

11.75:1

Step-by-step explanation:

alrighty right, more unit rates, so we have to get that 8 down to 1. How are we gonna do that? By dividing it by 8. And if we divide one side by 8, we also have to divide the other side:

8 ÷ 8 = 1

94 ÷ 8 = 11.75

So 94 hours to 8 days in lowest terms is 11.75 hours to 1 day

Answer:

TRUE

Step-by-step explanation:

Answer:

Perimeter of figure = 36.3

Step-by-step explanation:

We'll begin by calculating the perimeter of the rectangle. This can be obtained as follow:

Length (L) = 9

Width (W = 4

Perimeter of rectangle (Pᵣ) =?

Pᵣ = 2(L + W)

Pᵣ = 2(9 + 4)

Pᵣ = 2(13)

Pᵣ = 26

Next, we shall determine the perimeter of semi circle. This can be obtained as follow:

Diameter (d) = 4

Pi (π) = 3.14

Perimeter of semi circle (Pₛ) =?

Pₛ = ½(πd) + d

Pₛ = ½(3.14 × 4) + 4

Pₛ = ½(12.56) + 4

Pₛ = 6.28 + 4

Pₛ = 10.28

Finally, we shall determine the perimeter of the figure. This can be obtained as follow:

Perimeter of rectangle (Pᵣ) = 26

Perimeter of semi circle (Pₛ) = 10.28

Perimeter of figure =?

Perimeter of figure = Pᵣ + Pₛ

Perimeter of figure = 26 + 10.28

Perimeter of figure = 36.28 ≈ 36.3

Answer:

-9

Step-by-step explanation:

2(-x)² - 5 = 157

2x² - 5 = 157

add 5 to each side of the equation:

2x² = 162

divide both sides by 2:

x² = 81

√81 = 9 or -9

If you mean:

x² = 10

√x² = √10

x = √10

if you meant:

2x = 10

2x/2 = 10/2

x = 10/2

x = 5

Answer:

75%

Step-by-step explanation:

Answer:

75%

Step-by-step explanation:

In a box-and-whisker plot, the whiskers show the minimum and maximum while the edges of the box show the first and third quartiles. The line in the box shows the median.

Quartile means a quarter of the data.

We're trying to find out what percentage of the students scored between 70 and 100.

70 is right on the 1st quartile mark, while 100 is on the maximum mark.

This means that a quarter of students got lower than 70, and nobody scored over 100 (because it's a test and it's calculated in percentage).

If a quarter of students got lower than 70, that means three-quarters of students got 70 or higher. And since the maximum is 100, and that is also what we're trying to find, the answer is 3/4 of all students.

3/4 = 75%

Hence, the answer is 75%.

The statement first “The intersection of two planes is a line." option (a) is correct.

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have two planes, Y and Z intersecting each other.

The intersection of two lines is a point.

As we know, if the two planes intersect each other, the intersection will be a line.

If planes are parallel then there will no intersection.

Thus, the statement first “The intersection of two planes is a line." option (a) is correct.
