Here is a triangle with the height on the side of the triangle. Use the formula: (1/2)*(Base)*(Height) to find the area of the triangle at the left.
(If one square on the graph = one centimeter)
b = 10cm
b = 10cmh = 10cm
Area:
[tex] = \frac{1}{2} \times b \times \: h[/tex]
[tex] = \frac{1}{2 } \times 10 \times 10[/tex]
[tex] = \frac{1}{2} \times 100[/tex]
[tex] = 50 {cm}^{2} [/tex]

Find the perimeter of triangle ABC. Approximate to the nearest whole unit.
Answer: 16 units
Step-by-step explanation: adding the perimeter sides to get the perimeter of triangle ABC would be 4.1+6.1+5.8 = 16
Answer:
16
Step-by-step explanation:
AC = 6.1
CB = 5.8
BA = 4.1
Use whole number approximations for the three side lengths.
AC = 6
CB = 6
BA = 4
perimeter = AC + CB + BA = 6 + 6 + 4 = 16
Answer: 16
Please show your work and solve the proportion!
Answer:
x = 1/9
Step-by-step explanation:
we want to solve the proportion;
we simply cross multiply the values
Mathematically, that will be calculated as follows;
6x * 21 = 2 * 7
6x * 21 = 14
6x = 14/21
2(3x) = 2(7/21)
3x = 7/21
3x = 1/3
x = 1/3/3
x = 1/9
If g(x) = 2x2 + 6x + 5, use synthetic division to find g(-5).
=================================================
Explanation:
Check out the image below. I've posted the synthetic division table. The value at the very end of the bottom row is the remainder. By the remainder theorem, this is exactly the value of g(-5).
Recall the remainder theorem says: If you divide p(x) by (x-k), then the remainder is p(k). In this case, k = -5 is our test root which is the value placed in the box on the left.
As a way to check the answer, we can say
g(x) = 2x^2 + 6x + 5
g(-5) = 2(-5)^2 + 6(-5) + 5
g(-5) = 25
So the answer is confirmed.

What is 8b - ab + 7a subtracted from 3a - 9ab + b?
Answer:
10a-10ab-7b
Step-by-step explanation:
i dont feel like putting the steps but ik this is correct
The answer is -4a -8ab -7b after subtracting 8b - ab + 7a from 3a - 9ab + b.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
We have two expressions:
8b - ab + 7a and 3a - 9ab + b
After subtracting:
= (3a - 9ab + b) - (8b - ab + 7a)
= -4a -8ab -7b
Thus, the answer is -4a -8ab -7b after subtracting 8b - ab + 7a from 3a - 9ab + b.

Please can someone please help me with this one question??????
Answers:
angle K = 50 degreesangle L = 90 degreesangle KML = 40 degreesangle LMN = 140 degrees========================================================
Explanation:
Rule: The interior (inside) angles of a triangle always add to 180
K+L+M = 180
5x+9x+4x = 180
18x = 180
x = 180/18 ... divide both sides by 18
x = 10
That x value directly leads to...
angle K = 5x = 5*10 = 50 degreesangle L = 9x = 9*10 = 90 degrees (aka right angle)angle M = 4x = 4*10 = 40 degreesAs a check,
K+L+M = 50+90+40 = 180
This confirms we have the right x value.
--------------------------
We can further say,
angle KML = interior angle M = 40 degreesangle LMN = 180 - (angle KML) = 180 - 40 = 140 degreesnote how interior angles K and L add to exterior angle LMN
50+90 = 140
This is an application of the remote interior angle theorem.
Answer:
Angle K = 50
Angle L = 90
Angle KML = 40
Angle LMN = 140
Step-by-step explanation:
Solve for x. We know that triangles' interior angles add up to 180.
So, we can set the values to equal to 180 and solve for x.
5x + 9x + 4x = 180
Simplify.
18x = 180
Now, divide by 18.
x = 10
Now, plug 10 in for each angle.
Angle K = (5 * 10) = 50
Angle L = (9 * 10) = 90
Angle KML = (4 * 10) = 40
For this last angle, we use the supplementary theorem that says "angles that are supplementary to each other add up to 180".
So, we do angle LMN + 40 = 180
Angle LMN = (180 - 40) = 140

The population of Salisa is 12,500 and increases by 300 each month. The population of Corsair is 13,200 and increases by 200 each month. How many months will it take until the population of the two cities is the same?
It will take seven months for the population of each city to be the same.
On month seven, Salisa's population will be 14,600. (300x7=2,100+12,500=14600)
On month seven, Corsair's population will be 14,600 as well. (200x7=1,400+13,200=14600)

BED = 180°-65°
= 115°
Answer:
115°
Step-by-step explanation:
Since CE is perpendicular to AD , then ∠ AEC = 90° and
∠ BEC = 90° - 65° = 25° , then
∠ BED = ∠ BEC + ∠ DEC = 25° + 90° = 115°

Answer:
45
Step-by-step explanation:
Answer:
a = 45
b = 15
Step-by-step explanation:
From the information given, you can deduce that both ΔPQR and ΔPSR are isosceles triangles that share base PR. This means that ∠a = ∠SRP because the base angles of an isosceles triangle are always congruent.
Because the vertex of ΔPSR is 90°, you know that the base angles add up to 90 because 180(sum of a triangle's angles) - 90 = 90. 90/2 = 45, so a = 45.
To find b, you need to subtract the base angle of ΔPSR from the base angle of ΔPQR. ΔPQR's base angle is 60, because 180 - 60 = 120 and 120/2 = 60. 60 - 45 = 15, so b = 15.

3. A certain 50 cm spring will stretch (in
cm) the weight (in kg) attached to
it. How long will the spring be if a 35
kg weight is attached to it?
Complete Question
A certain 50 cm spring will stretch (in cm) one fifth the weight (in kg) attached to it. How long will the spring be if a 35 kg weight is attached to it
Answer:
The value is [tex]L_w = 57 \ cm[/tex]
Step-by-step explanation:
The length of the spring is [tex]L = 50 \ cm = 0.5 \ m[/tex]
The mass attached to it is [tex]w = 35 \ kg[/tex]
Generally given from that the spring will stretch one fifth of the weight (in kg)attached to it , it then means that the new length of the spring whenever a weight is attached to it is mathematically represented as
[tex]L_w = L + \frac{W}{5}[/tex]
=> [tex]L_w = 50 + \frac{35}{5}[/tex]
=> [tex]L_w = 57 \ cm[/tex]
Two angles of a Triangle measure 55° and 22° What is the measure of the third angle of the triangle
A. 15°
B. 90°
C. 105°
D. 285°
Answer:
c would be the closest
Step-by-step explanation:
All triangles equal 180*. so if you combine the 2 angles, which adds up to 77* then that would leave the third angle to be 103* but since that isnt an option choose c since its the closest.

The daily attendance at a bowling alley was recorded for 15 days. The scatterplot
shows the number of lanes rented each day and the number of people who bowled
that day. Which statement is best supported by the sscatterplot?
HELP PLEASE :(
Answer:
I am gonna assume 4.
Step-by-step explanation:
As we can see the more people who rent out a lane, there are more people bowling.
The statement is best supported by the scatterplot is D. There is a positive linear association between the number of lanes rented and the number of people who bowl.
How does the dot plot work?Suppose we're measuring something whose values are numeric. For each value of that thing we observe, we plot a dot above that value in the number line. Thus, the total number of dots in the dot plot tells us the total number of observations of the values of that thing.
Given that daily attendance at a bowling alley was recorded for 15 days.
The scatterplot represents the number of lanes rented each day and the number of people who bowled that day.
By looking at the scatter plot graph we will have that there is a positive linear association between the number of lanes rented and the number of people who bowl.
The statement is best supported by the scatterplot is D. There is a positive linear association between the number of lanes rented and the number of people who bowl.

Answer:
A Subtract the bottom equation from the top equation.B Add the equations.Step-by-step explanation:
The x-terms are the same in each equation, so subtracting one equation from the other will eliminate the x-variable.
The y-terms are opposites in the two equations, so adding the two equations will eliminate the y-variable.
Both strategies (subtracting, adding) are applicable to this system of equations.
