(a) The area of the triangle = 6 cm squares
(b) The area of the whole shape = 76 cm squares
The shape given is formed by a triangle and a rectangle.
First we need to find the area of the triangle.
Height of the triangle = 3 cm
Base of the triangle = 4 cm
Area of the triangle = 1/2 x base x height
= 1/2 x 4 x 3
= 6 cm squares
Area of the whole shape = Area of the triangle + Area of the rectangle
Length of the rectangle = 10 cm
Width of the rectangle = 7 cm
Area of the rectangle = length x width
= 10 x 7
= 70 cm squares
Therefore, area of the whole shape = 6 + 70

Sketch the graph of the line (need answer ASAP!!)
The graph of the linear equation:
y = -3x + 4

How to sketch the graph of the line?
To draw a line, we just need to find two points that belong to the line, graph them, and then connect them with a line.
Here we know that we have the line:
y = k*x + 4
Where k = -3, then:
y = -3*x + 4
By evaluating this in a value of x, for example, x = 0, we will get:
y = -3*0 + 4 = 4
Then we also have the point (0, 4) (and the given one, (2, -2))

Positive 140
Negative 18
The probability is approximately.
The probability of getting someone who tested positive, given that he or she did not have the disease is 0.985
What is probability ?Probability is what has the potential to happen. This area of math examines how random events happen. A value between 0 and 1 is used to express it. In order to anticipate the possibility of events, probability has been introduced to mathematics. The degree of likelihood that something will happen can be used to define probability. This fundamental theory of probability, which is also applied to the probability distribution, can be used to estimate the likelihood of the results of a random experiment. We must first determine the total number of alternatives in order to determine the likelihood that a specific event will occur.
Given that : He or she did not have the disease. The individual actually had the disease No positive 9 , negative 133 Yes Positive 140 ,Negative 18 .
Yes No
Positive : 140 9

Si la suma de un número y 5 se multiplica por 3, el resultado es igual a 7 veces el número
disminuido en 13. Halla el número.
We construct an equation and calculate that number as 7 .
The equals sign is a symbol used in mathematical formulas to denote the equality of two expressions. The word equation and its cognates can have slightly different meanings in different languages. For instance, in English, an equation is any well-formed formula that consists of two expressions linked by the equals sign, whereas in French, an equation is defined as containing one or more variables.
The equation's solutions are the values of the unknown variables that satisfy the equality, which are often referred to as the variables for which the equation must be solved.
let the number be x .
9 times the number is = 9x
5 times the number added to 3 is
(x + 3) × 5
Now let us set up an equation and find that number :
(x + 3) × 5 = 9x - 13
Simplifying the given equation we get :
5 (x + 3) = 9x - 13
5x + 15 = 9x - 13
5x - 9x = - 13 - 15
- 4x = - 28
x = - 28/-4
x = 7

If Betty spent $56 to mail her package, how many pounds did it weigh?
1. The mathematical expression that can be used to determine the total cost of mailing a package weighing p pounds is f(Tc) = 20 + 3p.
2. Since Betty spent $56 to mail her package, the weight in pounds of the mail must be 12 pounds.
What is a mathematical expression?A mathematical expression is a statement containing numbers, variables, and an arithmetic operation.
Flat (fixed) rate for mailing a package = $20
Variable mailing rate per pound = $3
Expression to model the total cost:
Let Tc = total cost
p = number of pounds
Tc = 20 + 3p
If Betty spent $56 to mail her package, the number of pounds, using the mathematical expression above:
Tc = 20 + 3p
56 = 20 + 3p
56 - 20 = 3p
36 = 3p
p = 12

you borrow $200,000.00 that charges you 6.3% interest, compounded monthly. You will make payments monthly in the amount of $1,300.00. How many payments will it take for you to pay off the loan?
The number of payments to pay off the loan of $200,000 at 6.3% interest, compounded monthly is 315 monthly payments.
How is the number of payments computed?Using the compounding format for determining the monthly payments, the number of periods for the periodic payments can be computed.
In this situation, we used the online finance calculator to determine the number of payments.
Compounding accumulates the interest on a loan and adds it to the principal for computing subsequent interest.
At the end of the period, the balance is made up of the principal and compounded interest.
I/Y (Interest per year) = 6.3%
PV (Present Value) = $200,000
PMT (Periodic Payment) = $-1300
FV (Future Value) = $0
Results:
N (# of periods) = 314.854
Sum of all periodic payments = $-409,309.97
Total Interest $209,309.97
Thus, you are likely to make 315 monthly payments to settle the loan.
