Answer:

we are missing some information, so I looked for a similar question and found the attached image:

Cincinnati's total population = 298,957 people

Cincinnati's population over age 25 = 193,638

I added all the people that were up to 24 years old and then subtract that number from 298,957 - 105,319 = 193,638

Percentage of Cincinnati residents over age 25 that have a bachelor's degree or higher = 66,722 / 193,638 = 0.3446 = 34.46%

Answer:

c. 9 det A

Step-by-step explanation:

Given the following data;

Since A is a square matrix of order 2, we know that n = 2

K = 3

For any scalar k;

∣kA∣ = k^{n} ∣A∣

Substituting into the equation;

∣-3A∣ = -3²∣A∣

Simplifying, we have;

∣-3A∣ = 9∣A∣

= 9 detA

Therefore, det (-3A) = 9 detA

Answer: the answer is -2 1/3

Step-by-step explanation: it would be -2 1/3 because 5 + 2=7 and then add the 1/3 to make -7 1/3

The number that makes the equation

[tex]\rm -5 +x = -7\dfrac{1}{3}[/tex]     true is [tex]\rm \bold {-2\dfrac{1}{3} }[/tex].

So option 4 is correct.

Let the number that makes equation true is x

The question is that what makes equation true

[tex]\rm -5 +x = -7\dfrac{1}{3}[/tex]

This equation is a linear expression with one variable and rational numbers.

This equation can be solved in the following way

[tex]\rm -5 +x = -\dfrac{22}{3} \\x = 5 -\dfrac{22}{3} \\x = (15-22)/3 \\x = -7/3\\ x= -2\dfrac{1}{3}[/tex]

So from the given options in figure  we can see that option 4 is correct

We would have to divide every single one of these fractions to find out if they were terminating decimal. 2/5 = 2divided by 5 = 0.4 as you can see no many other repeating numbers after the decimal. We don't have to do the rest since we now know the answer is 2/5.

Answer:

(C).The solid ball of radius 5 centered at (0,0,0) with the interior of the solid ball of radius 1 centered at (0,0,0) removed.

Step-by-step explanation:

These are the equation of Spheres

In the equation [tex]1\leq x^2 + y^2 + z^2 \leq 25[/tex], when we will take square root of 25 we will get radius as 5 so the Sphere is varying from radius 1 to 5, Which will make it into a Solid sphere with the center at (0, 0, 0)

In the equation [tex]x^2 + y^2 + z^2 \leq 25, x \geq 0[/tex] it is given that the sphere is less than

radius 5 units.

Also there will be no sphere with radius from 0 to 1 because the sphere is starting from radius 1 and increasing till radius 5.

Therefore, The sphere is a solid increasing from radius 1 to 5.

and another solid sphere is removed from inside with radius increasing from 0 to 1.

Answer:

The value of a=4

Step-by-step explanation:

Given the matrix

[tex]B=\begin{pmatrix}1\:&\:2\:\\ \:\:\:2\:&\:a\end{pmatrix}[/tex]

so solving the matrix B by taking its determinant to get the value a

[tex]\det \begin{pmatrix}1&2\\ 2&a\end{pmatrix}=0[/tex]

as according to determinant formula

[tex]\det \begin{pmatrix}a\:&\:b\:\\ c\:&\:d\:\end{pmatrix}\:=\:ad-bc[/tex]

 [tex]1\cdot \:a-2\cdot \:2=0[/tex]    

  [tex]a-4=0[/tex]

   [tex]a=4[/tex]          

Therefore, the value of a=4

2nd day: 3 seashells, 7.35 dollars

3rd day: 7 seashells, 17.15 dollars

All together: 39.2 dollars

day 3 = 7

day 2 = 7 - 4 = 3

day 1 = 3 * 2 = 6

total seas shells = 7 + 3 + 6 = 16

Answer:

$1.94

Step-by-step explanation:

Cost of 3 folders = $2.91

We need to find the cost of 2 folders.

First we will find the cost of 1 folder

1 folder = $2.91/3 = $0.97

To find the cost of 2 folders, multiply $0.97 and 2

2 folders = $0.97 × 2

= $1.94

Hence, the cost of 2 olders is $1.94.
