The roof gable on Charlene's house has two
equal sides. One angle measures 110.4°. The
other two angles are equal to each other.
Estimate the measure of each of the other
two angles.
Each of the other two angles in the roof gable measures approximately 34.8°.
How to calculate the valueIf the roof gable on Charlene's house has two equal sides, and one angle measures 110.4°, we can determine the measure of each of the other two angles by using the fact that the sum of the angles in a triangle is always 180°.
Let's denote the measure of the other two angles as x.
Since the two equal sides of the gable form an isosceles triangle, the two angles opposite those sides are equal.
Therefore, we have:
x + x + 110.4° = 180°
Combining like terms:
2x + 110.4° = 180°
Now, let's solve for x:
2x = 180° - 110.4°
2x = 69.6°
x = 69.6° / 2
x = 34.8°
Therefore, each of the other two angles in the roof gable measures approximately 34.8°.

Find ƒ(1)
for the given
When x is equal to 1, the Function f(x) = -4x - 5 yields a value of -9.
The find ƒ(1) for the function f(x) = -4x - 5, we need to substitute x = 1 into the function and evaluate the expression.
Replacing x with 1, we have:
ƒ(1) = -4(1) - 5
Simplifying further:
ƒ(1) = -4 - 5
ƒ(1) = -9
Therefore, when x is equal to 1, the value of the function f(x) = -4x - 5 is ƒ(1) = -9.
Let's break down the steps taken to arrive at the solution:
1. Start with the function f(x) = -4x - 5.
2. Replace x with 1 in the function.
3. Evaluate the expression by performing the necessary operations.
4. Simplify the expression to obtain the final result.
In this case, substituting x = 1 into the function f(x) = -4x - 5 gives us ƒ(1) = -9 as the output.
It is essential to note that the notation ƒ(1) represents the value of the function ƒ(x) when x is equal to 1. It signifies evaluating the function at a specific input value, which, in this case, is 1.
Thus, when x is equal to 1, the function f(x) = -4x - 5 yields a value of -9.

The rules for the two graphs above are: A. first graph: y = 3 + x; second graph : y = 6 + x.
How to determine an equation of this line?In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation (formula):
y - y₁ = m(x - x₁)
Where:
x and y represent the data points.m represent the slope.First of all, we would determine the slope of graph 1;
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
Slope (m) = (4 - 3)/(1 - 0)
Slope (m) = 1/1
Slope (m) = 1
At data point (0, 3) and a slope of 1, a linear equation for this line can be calculated by using the point-slope form as follows:
y - y₁ = m(x - x₁)
y - 3 = 1(x - 0)
y = x + 3
Next, we would determine the slope of graph 2;
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
Slope (m) = (7 - 6)/(1 - 0)
Slope (m) = 1/1
Slope (m) = 1
At data point (0, 6) and a slope of 1, a linear equation for this line can be calculated by using the point-slope form as follows:
y - y₁ = m(x - x₁)
y - 6 = 1(x - 0)
y = x + 6

You would need approximately 225 mL of the 70% alcohol mixture to obtain the desired 55% solution.
To find out how much of the 70% alcohol mixture you need to obtain a 55% solution, we can set up an equation based on the principle of mixing concentrations.
Let's assume you need "x" mL of the 70% alcohol mixture.
First, we'll determine the amount of alcohol in the 10% alcohol mixture:
Alcohol in 10% mixture = 10% of 75 mL
= (10/100) × 75 mL
= 7.5 mL
Next, we'll determine the total amount of alcohol in the desired 55% solution:
Alcohol in 55% solution = 55% of (75 mL + x mL)
We want the amount of alcohol in the 55% solution to be equal to the sum of the alcohol in the 10% mixture and the alcohol in the x mL of the 70% mixture.
Therefore, we can set up the equation:
Alcohol in 55% solution = Alcohol in 10% mixture + Alcohol in 70% mixture
55% of (75 mL + x mL) = 7.5 mL + 0.7x mL
Now, let's solve for "x" to find the amount of the 70% alcohol mixture needed:
0.55 × (75 mL + x mL) = 7.5 mL + 0.7x mL
41.25 mL + 0.55x mL = 7.5 mL + 0.7x mL
0.55x mL - 0.7x mL = 7.5 mL - 41.25 mL
-0.15x mL = -33.75 mL
x mL = (-33.75 mL) / (-0.15)
x mL ≈ 225 mL
Therefore, you would need approximately 225 mL of the 70% alcohol mixture to obtain the desired 55% solution.

B) Determine the t-intercept and explain its meaning in terms of the problem. (T,P)
Answer A ; 4934 is the P-intercept. which indicates that 4934 people called Minnesota home in 2000.
Answer B ; T-intercept is -4934/37, or approximately -133. This indicates that Minnesota had a population of 2000–133 in 1867.
Answer A : P=37t+4934 can be used to represent Minnesota's population in thousands over the t years after 2000.
P-intercept is the P value at time t=0.
P=37*0+4934\sP=0+4934\sP=4934
So, 4934 is the P-intercept. which indicates that 4934 people called Minnesota home in 2000.
Answer (B) : The term "t-intercept" refers to the value of the function t when P=0 0=37t+4934 -4934=37t divide by 37 -4934/37=t -133.351351351 = t
Hence T-intercept is -4934/37, or approximately -133. This indicates that Minnesota had a population of 2000–133 in 1867.
P=37t+4934 P-intercept means the value of P at t=0 P=37*0+4934 P=0+4934 P=4934

the level of temperature of liquid in a thermometer is 26.52'c lower than the boiling poin. of water. what is the thermometer reading
The thermometer reading would be 73.48°C.
The boiling point of water is generally considered to be 100°C. According to the given information, the temperature of the liquid in the thermometer is 26.52°C lower than the boiling point of water. Therefore, to find the thermometer reading, we subtract 26.52 from 100.
100 - 26.52 = 73.48
Hence, the thermometer reading would be 73.48°C.
In this scenario, we are assuming that the thermometer is calibrated to measure temperature in Celsius. The boiling point of water at standard atmospheric pressure is 100°C, and the given information states that the liquid in the thermometer is 26.52°C lower than the boiling point.
By subtracting 26.52 from 100, we obtain a reading of 73.48°C.
Thermometers work by utilizing the principle that certain substances, such as mercury or alcohol, expand or contract with changes in temperature. The expansion or contraction is measured using a scale, which is marked with various temperature values.
In this case, the thermometer is calibrated in Celsius, so we refer to the Celsius scale. By subtracting 26.52 from 100, we find the temperature at which the liquid in the thermometer is settled, which is 73.48°C.

a man gets a job with a salary of 40000 dollars a year. he is promised a 2090 dollars raise each subsequent year. his total earning for a 8-year period is dollars.
Total earnings for an 8-year period is - 378520 dollars.
The salaries, year by year, can be written in a sequence
40000, 40000 + 2090 , 40000 + 2(2090)......
which is an arithmetic sequence, with
a=40,000 , d=2090
and the general term
\(a_{n}\) = 40000 + 2090 (n - 1)
gives the salary at the beginning of year n.
Recall that for the arithmetic sequence,
\(a_{n}\) = \(a + (n - 1 )d\)
the nth partial sum is given by either of the equivalent formulas:
\(S_{n} = \frac{n}{2} [2a + (n - 1 )d ]\)
we find \(S_{8}\) = the sum of the first 8 salaries:
\(S_{n} = \frac{8}{2} [2. 40000 + (8 - 1 )2090 ]\)
= 4 [ 80000 + 7 × 2090 ]
= 4 [ 80000 ++ 14630 ]
= 4 × 94630
= 378520
So, total earnings for an 8-year period is - 378520 dollars.

The sum of the angles of a triangle is 180°. If one angle of a triangle measures x and the second angle measures (5x +19)º
express the measure of the third angle in terms of x. Simplify the expression
Answer:
third angle = (-6x + 161)°
Step-by-step explanation:
180° = (x)° + (5x + 19)° + third angle →
180° = (6x + 19)° + third angle →
180° – (6x + 19)° = (6x + 19)° + third angle – (6x + 19)° →
180° – (6x + 19)° = third angle →
180° + -(6x + 19)° = third angle →
180° + (-6x)° + (-19)° = third angle
180° – 6x° – 19° = third angle
(180° – 19°) – 6x° = third angle
161° – 6x° = third angle
third angle = 161 – 6x°
third angle = -6x° + 161°
third angle = (-6x + 161)°

8x-48 = -x-3
add 48 to both sides
8x-48+48 = -x-3+48
8x = -x + 45
Add x to both sides
8x+x = -x+x+45
9x = 45
