The measure of the top, vertex angle of an isosceles triangle is option c 100 degrees
Given,
The base angle of an isosceles triangle = 40 degrees
We have to find the top, vertex angle:
Isosceles triangle:
Therefore, an isosceles triangle has two equal sides as well as two equal angles. The Greek words iso (same) and skelos are the source of the name (leg). An equilateral triangle is one in which all of its sides are equal, whereas a scalene triangle is one in which none of its sides are equal.
Here,
We know that total interior angle of a triangle is 180°
In an isosceles triangle base angles will be equal.
Here, base angle is 40 degrees.
Now, the top, vertex angle = total angle - base angle × 2
= 180 - 40 × 2
= 180 - 80
= 100
That is, the top, vertex angle of an isosceles triangle is 100°

The pages read by Luis, Dayja and Michael read all together is 252.
What is Percentage?
A relative value indicating hundredth part of any quantity is called percentage.
Given that;
The conditions is,
Luis read 75% more pages than Dayja, and Dayja read 75% more pages than Michael.
Total pages read by Dayja = 84
Now,
Since, Luis read 75% more pages than Dayja.
So, The pages for Luis = 75% of 84
= 75/100 × 84
= 6,300 / 100
= 63
Thus, Pages for Luis = 84 + 63
= 147
And, Number of pages read by Michael = 84 - 63
= 21
Thus, Number of pages read by Michael = 21
So, Total number of pages read by Luis, Dayja and Michael all together is;
= 84 + 147 + 21

The size of the angle marked t is 60 degrees.
We are given an isosceles triangle with one angle as 30 degrees.
We have to find the angle marked t.
Let us name the triangle.
Let the vertex formed by the intersection of two equal sides be A and,
The vertex with 30 degree angle be B and the third vertex be C.
We know that,
AB = AC
Hence,
∠ ABC = ∠ ACB = 30 degrees.
Hence, ∠ BAC = 180 - 30 - 30 = 120 degrees
We know that,
t + ∠ BAC = 180 degrees (supplementary angles)
Hence,
t + 120 = 180
t = 180 - 120
t = 60 degrees

The zurn family ate at a restaurant that was having 15% discount on that day .Their meal costs 64.75,and they left a 20% tip .What is the total cost of the meal? (Note: the tip applies to the total cost of the meal before the discount was applied)
The total cost of the meal is 66.045
Given,
The cost of the meal = 64.75
The discount given on that day = 15%
The tip given by Zurn family = 20%
We have to find the total cost of the meal.
First we have to find the total cost including tip before discount is added.
That is,
120% of 64.75
= 64.75 × 120/100
= 6.475 × 12
= 77.7
Here, the total cost including tips before discount is 77.7
Now, we have to deduct the discount.
100 - 15 = 85
That is,
85% of 77.7 will be the total cost of the meal
= 77.7 × 85/100
= 6604.5 / 100
= 66.045
Therefore, the total cost of the meal is 66.045

60=<B
m<BCD= 70
m<DBC= 60
70-60=10
Answer:
О A = 10°
Step-by-step explanation:
∡ DBC = 180 - 130 = 50°
∡ DBC + ∡ CBD + ∡ BCD = 180°
50° + 70° + ∡BCD = 180°
∡BCD = 180° - (50°+70°)
∡BCD = 180° - 120°
∡BCD = 60°
Then:
∡BCD - ∡DBC = 60° - 50° = 10°

x2+2x-12=0 vertex form
Taking into account the definition of vertex form, the quadratic function y=x² +2x-12 in vertex form is f(x) = 1(x - +1)² -13
Vertex form of a quadratic functionThe function f(x) = ax²+ bx + c with a, b, c real numbers and a ≠ 0, is a quadratic function expressed in its polynomial form.
The graph of a quadratic function is a curve called a parabola.
Every quadratic function can be expressed by f(x) = a(x - h)² + k
where
"a" is the main coefficient.the ordered pair (h;k) are the coordinates of the vertex of the parabola.The value of -b÷(2a) indicates the value of x or h and replacing this value into the function, you get the value of y or k of the vertex of the function.
Vertex form in this caseIn this case, the quadratic equation y=x² +2x-12, where:
a= 1b= 2c= -12The value of x or h of the vertex is calculated as -2÷(2×1)
Solving: -2÷2= -1
The value of y or k of the vertex of the function is calculated as y=(-1)²+2×(-1) -12
Solving y= -13
Finally, the quadratic function can be expressed in vertex form by f(x) = 1(x - +1)² -13

What is subtraction?To subtract in mathematics is to take something away from a group or a number of objects. The group's total number of items decreases or becomes lower when we subtract from it. The components of a subtraction issue are the minuend, subtrahend, and difference. An arithmetic operation called subtraction simulates the process of deleting items from a collection. The action of subtracting a matrix, vector, or other quantity from another according to predetermined rules in order to find the difference.
Given that,
Isaac has 18 coins, all quarters and nickels.
The total value of the coins it $3.50.
Let the quarters be x and nickels be y
x+ y= 18
x= 18 - y... equation 1
1 quarter is 0.25
1 nickel is 0.05
So,
0.25x+ 0.05y= 3.50
substitute x value in above equation
0.25(18-y)+0.05 = 3.50
4.5-0.25y+ 0.05 = 3.50
4.55 - 3.50 = 0.25y
1.05= 0.25y
y= 4.2

Two values of v satisfy the equation |2v- 13| +6 = 9. What is the sum of these values?
Answer: v = 8, 5; The sum of these values would be 13.
∣2v − 13∣ + 6 = 9
Combine like terms, utilizing the properties of equality. Do not forget to follow the order of operations!
∣2v − 13∣ + 6 = 9
Subtract 6 from both sides of the equation.
∣2v − 13∣ = 3
Consider the definition of absolute value (distance from the number zero); the absolute value of x and -x would both be x.
2v − 13 = 3
2v − 13 = −3
Add 13 to both sides of the equation.
2v = 16
2v = 10
Divide both sides of the equation by 2.
v = 8
v = 5
Add the sum of the values.
8 + 5 = 13
