Answer:
Susana will have 107 students.
Step-by-step explanation:
Becca have students = 115
Susana has 8 fewer students than Becca.We can write its as:
Becca has 115 students, so Susana will have 115-8 = 107 students
Because fewer means less than so, 8 less than 115 is 115-8
Erika has 25 more students than Susana.We can write it as:
Susana has 107 students, so Erika will have: 107+25 = 132 students.
because more means we need to add 25 students with number of students in Susana class.
So, Susana will have 107 students.

Which equation represents g(x) as a transformation of
g(x) = f(x) -5
g(x) = f(x - 5)
g(x) = f(x) + 5
g(x) = f(x + 5)
Answer:
g(x)=f(x)-5
Step-by-step explanation:
the negative inside the parenthesis reduces the x values but we have the y value reduced by 5 here so it goes outside
The equation represents g(x) as a transformation will be g(x) = f(x) - 5. Then the correct option is A.
What is a function?A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.
From the graph, we can observe that the function g(x) is 5 units below the function f(x).
If the function gets shifted downward by k units then the k is subtracted from the function. Then the function g(x) is given as,
g(x) = f(x) - 5
The equation represents g(x) as a transformation will be g(x) = f(x) - 5. Then the correct option is A.

4,320 is divisible by?
3
9
10
Answer:
3, 9, and 10
Step-by-step explanation:
To figure out whether 4,320 is divisible by these numbers, we can use their divisibility rules to help us out.
A number is divisible by 3 or 9 if its digits add up to a number divisible by 3 or 9. The digits of 4,320 add to 4 + 3 + 2 + 0 = 9, which is divisible by both 3 and 9, so 4,320 is divisible by 3 and 9.
A number is divisible by 10 if its last digit is a 0, which we have here, so 4,320 is divisible by 10.

The matrix that represents the system of equations is:
| 3 -2 |
| 4 -1 |
What are Systems of equations?Simultaneous equations, a system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.
There are four methods for solving systems of equations: graphing, substitution, elimination, and matrices.
We can write the system of equations in matrix form as AX = B, where:
A = the coefficient matrix of x and y coefficients
X = the column matrix of variables x and y
B = the column matrix of constants on the right-hand side of the equations
The matrix A is obtained by taking the coefficients of x and y from the left-hand side of the equations:
A = | 3 -2 |
| 4 -1 |
The matrix B is obtained by taking the constants from the right-hand side of the equations:
B = | 9 |
| 12 |
So the system of equations can be represented as:
| 3 -2 | | x | | 9 |
| 4 -1 | x | y | = | 12 |
Therefore, the matrix that represents the system of equations is:
| 3 -2 |
| 4 -1 |

Find CD, if BC = 3 in
459
B В
D
Answer:
CD = (3√2)/2 = 2.12 in.
Step-by-step explanation:
Reference angle = m<BCD = 45°
Hypotenuse = BC = 3 in.
Adjacent side = CD = ??
Apply trigonometric ratio
Cos(45) = CD/3
Multiply both sides by 3
3*Cos(45) = CD
3*√2/2 = CD (cos 45 = √2/2)
(3√2)/2 = CD
CD = (3√2)/2 = 2.12

A hiker want to determine the height of a cliff. She
has measured her height (5.8ft) and shadow (7ft).
She knows the cliff casts a shadow of 50ft. How
tall is the cliff?
Answer:
41.43 ft
Step-by-step explanation:
We solve the above using proportion
Height of cliff/Shadow of cliff = Height of Hiker/Shadow of hiker
Height of cliff = x
Shadow of cliff = 50ft
Height of Hiker = 5.8 ft
Shadow of hiker = 7 ft
Therefore:
x/50 = 5.8/7
Cross Multiply
7x = 50 × 5.8
7x = 290
x = 290/7
x = 41.428571429 ft
Approximately = 41.43 ft
Therefore, the height of the cliff = 41.43 ft

ABCD diagonals intersect at E. If m∠BAC=4x+5 and m∠CAD=5x-14, then find m∠CAD.
Answer: m∠CAD = 81°
Step-by-step explanation: Diagonal is a line that unites opposite sides.
ABCD is a prallelogram. One property of diagonal in a parallelogram is it separates the parallelogram in 2 congruent triangles.
The figure below shows ABCD with its diagonals.
Since diagonal divides a parallelogram in 2 congruent triangles, it means the internal angles are also congruent. So
m∠BAC = m∠CAD
4x + 5 = 5x - 14
x = 19
Then, m∠CAD is
m∠CAD = 5(19) - 14
m∠CAD = 81
The angle m∠CAD is 81°.

Answer:
C. [tex]3.2\times 10^{1}[/tex]
Step-by-step explanation:
[tex]d_r[/tex] = Diameter of a red blood cell = [tex]0.0008\ \text{cm}[/tex]
[tex]d_w[/tex] = Diameter of a whooping cough virus = [tex]2.5\times 10^{-5}\ \text{cm}[/tex]
Ratio of the diameter of the red blood cell to the diameter of the whooping cough virus
[tex]\dfrac{d_r}{d_w}=\dfrac{0.0008}{2.5\times 10^{-5}}=\dfrac{0.0008}{25\times 10^{-6}}=\dfrac{0.0008\times 10^6}{25}\\\Rightarrow \dfrac{d_r}{d_w}=\dfrac{800}{25}\\\Rightarrow \dfrac{d_r}{d_w}=32=3.2\times 10^{1}[/tex]
The required ratio is [tex]3.2\times 10^{1}[/tex].
