Find the measure of angle a
Answer:
angle A = 47°
angle B= 48°
Step-by-step explanation:
4x+ 4x+ 4+3+85=180°
8x+92=180°
8x= 180-92
8x= 88°
x= 11°
angle A = 4(11)+3= 47°
angle B = 4(11)+4= 48°

Can someone Plz help me on this........
Answer:
1) a≥−2.5
2) n<1.2
3) b≥−0.8
4) false,
5) r≤0.1
6) y≤0.8
Step-by-step explanation:
1) Divide both sides by -3.2.
−3.2a/-3.2 ≤ 8/-3.2
2) Flip the equation
- n+0.8<2
Subtract 0.8 from the sides
n+0.8−0.8<2−0.8
3) Add 4.2 to both sides.
b−4.2+4.2≥−5+4.2
4) inequality cannot be solved
5) Simplify both sides of the inequality.
−r+5.1≥5
Subtract 5.1 from both sides.
−r+5.1−5.1≥5−5.1
−r≥−0.1
Divide both sides by -1.
-r/-1 ≥ -0.1/-1
6) Flip the equation.
−1.8y≥−1.44
Divide both sides by -1.8.
−1.8y/−1.8 ≥ −1.44/−1.8
good luck with your work!!

What is the length of the altitude of the equilateral triangle below?
Answer:
Step-by-step explanation:
It would be helpful if you could share the diagram of the equilateral triangle.
All 3 sides are equal, as are all 3 angles.
The altitude is perpendicular to the base. The altitude, h, is equal to
h = s*( (√3) / 2, where s is the length of one side of the triangle.

What is the equation of the blue line?
Answer:
Step-by-step explanation:
The blue line is the translate in the direction of the red line by , and therefore has equation y = 3 ( x − 4 ) + 5 or y = 3 x − 7 .
The linear equation is y = -x - 1 for the graph of the linear equation where -1 is the slope of the linear equation and -1 is the y-intercept.
What is a linear equation?It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.
If in the linear equation one variable is present then the equation is known as the linear equation in one variable.
As we can see from the graph of the linear equation:
The x-intercept a = -1
And the y-intercept b = -1
We know the linear equation in terms of a and b can be modeled:
[tex]\rm \frac{x}{a} +\frac{y}{b} =1\\\\\rm \frac{x}{-1} +\frac{y}{-1} =1\\\\[/tex]
x + y = -1
y = - x - 1
Thus, the linear equation is y = -x - 1 for the graph of the linear equation where -1 is the slope of the linear equation and -1 is the y-intercept.

The Barber are keeping track of their family energy costs. It costs the Barbers $0.16 per week to run their dishwasher. How much will it cost them to run their dishwasher for 52 weeks
Answer:
It will cost them $8.32 to run their dishwasher for 52 weeks.
Step-by-step explanation:
With the information provided, you can say that the cost to run the dishwasher is equal to the cost per week for the number of weeks, which would be:
Total cost=$0.16*number of weeks
Since you want to determine the cost to run the dishwasher for 52 weeks, you can replace the number of weeks in the formula to get the answer:
Total cost=$0.16*52
Total cost=$8.32
According to this, the answer is that it will cost them $8.32 to run their dishwasher for 52 weeks.

Answer:
The answer (in scientific notation) should be 1.8 x 10^2.
Step-by-step explanation:
(2 x 10^6) x (0.00009) = ?
(2 x 1,000,000) x (0.00009) = ?
2,000,000 x (0.00009) = 180
180 as a scientific notation is 1.8 x 10^2.
What is the solution to the equation? -3x + 7 = -2
What is the length of the each side?
please someone help
Answer:
each side 5
Step-by-step explanation:
with 2 equal internal base angles, we know this is an isosceles triangle
this being isosceles also tells us that the 2 opposite sides are also equal
Therefore: x + 2 = 3x - 4
solving for x
x - 3x = -4 -2
-2x = -6
x = -6 ÷ -2
× = 3
substituting x:
x +2 = 3 + 2 = 5
3x-4 = 9 - 4 = 5
A sequence is recursively defined as a(n)=2a(n-2) for values of n>2. Find the seventh term of the sequence if a(1)=0 and a(2)=1
Answer:
a(7) = 21
Step-by-step explanation:
Using the recursive formula and a(1) = 0, a(2) = 1 , then
a(3) = a(2) + 2a(1) = 1 + 2(0) = 1 + 0 = 1
a(4) = a(3) + 2a(2) = 1 + 2(1) = 1 + 2 = 3
a(5) = a(4) + 2a(3) = 3 + 2(1) = 3 + 2 = 5
a(6) = a(5) + 2a(4) = 5 + 2(3) = 5 + 6 = 11
a(7) = a(6) + 2a(5) = 11 + 2(5) = 11 + 10 = 21

Substituting the value of y from equation ( iii ) in equation ( ii ) , we get :

Identify the scale factor when we scale up from Figure S to T. Just write the number.
Answer:
Scale factor = 4
Step-by-step explanation:
Scale factor = [tex]\frac{\text{Dimension of the image}}{\text{Dimension of preimage or original}}[/tex]
Since, S is being dilated with a scale factor to form T,
So, the figure S is the preimage and figure T will be the image,
Length of one side of image T = 8
Length of one side of preimage = 2
Therefore, Scale factor = [tex]\frac{8}{2}[/tex]
= 4
Scale factor by which figure S has been dilated to form figure T is 4.

On a team, 7 girls and 2 boys scored a total of 64 points. The difference between the number of points scored by the 7 girls and the number of points scored by the 2 boys is 48. Each girl scored the same number of points and each boy scored the same number of points. Find the number of points scored by each girl and each boy.
Answer:
Each girl scores 8 points while each boy scores 4 points
Step-by-step explanation:
Let the number of point scored by the 7 girls and 2 boys be x and y respectively.
Thus, since 7 girls and 2 boys scored a total of 64 points, then;
7x + 2y = 64 - - - (1)
Also, difference between the number of points scored by the 7 girls and the number of points scored by the 2 boys is 48. Thus;
7x - 2y = 48 - - - (2)
Add eq(1) to (eq 2) to get;
14x = 64 + 48
14x = 112
x = 112/14
x = 8
Put 8 for x in eq(1) to get;
7(8) + 2y = 64
56 + 2y = 64
2y = 64 - 56
2y = 8
y = 8/2
y = 4
Thus,each girl scores 8 points while each boy scores 4 points
