Answer:
q = 4.9
m∠R = 27.1°
m∠S = 136.9°
Step-by-step explanation:
To solve the triangle we will use the cosine rule and the sine rule
In the given triangle
∵ q is the opposite side of ∠Q
∵ s is the opposite side of ∠S
∵ r is the opposite side of ∠R
∵ m∠Q = 16°
∵ r = 8 and s = 12
→ By using the cosine rule to find q
∴ q² = r² + s² - 2 r s cos∠Q
→ Substitute the values of r, s, and ∠Q in the rule above
∵ q² = (8)² + (12)² - 2(8)(12)cos(16°)
∴ q² = 23.43775438
→ Take √ for both sides
∴ q = 4.841255455
→ Round it to the nearest tenth
∴ q = 4.9
→ To find angles R and S we will use the sine rule
∵ [tex]\frac{r}{sin(R)}[/tex] =[tex]\frac{q}{sin(Q)}[/tex] = [tex]\frac{s}{sin(S)}[/tex]
→ Use the first two ratios to find m∠R
∵ [tex]\frac{8}{sin(R)}[/tex] = [tex]\frac{4.841255455}{sin(16)}[/tex]
→ By using cross multiplication
∴ 4.841255455 × sin(R) = 8 × sin(16)
→ Divide both sides by 4.841255455
∴ sin(R) = 0.4554807874
→ Use [tex]sin^{-1}[/tex] to find m∠R
∵ m∠R = [tex]sin^{-1}[/tex] (0.4554807874)
∴ m∠R = 27.0958732
→ Round it to the nearest tenth
∴ m∠R = 27.1°
∵ The sum of the measures of the angle in a triangle is 180°
∴ m∠S + m∠Q + m∠R = 180°
→ Substitute the values of m∠Q and m∠R
∵ m∠S + 16° + 27.1° = 180°
∴ m∠S + 43.1 = 180
→ Subtract 43.1 from both sides
∴ m∠S = 136.9°
Find the range of the graphed function.
A. Y is all real numbers
B. Y>_0
C. 0<_y<_10
D. -9<_y<_5
Btw, <_ or >_ is the greater than or equal to or less than or equal to sign.
Answer:
The range of the function should be:
-9 ≤ y ≤ 5
Hence, option D is true.
Step-by-step explanation:
We know that the set of values of the dependent variable for which a function is defined.
From the given function, we can easily observe that the graph is kind of oscillating between the y-value y = 5 and y = -9.
i.e.
at y = 5, the graph gets its maximum value
at y = -9, the graph gets its minimum value
Thus, the range of the function should be:
-9 ≤ y ≤ 5
Hence, option D is true.

Answer:
Equation: [tex]2(x+8)+2(3x-5)+23 = 126[/tex]
[tex]x = 12.125[/tex]m
[tex]AB = 20.125[/tex]m
[tex]EF=31.375[/tex]m
Step-by-step explanation:
The equation of the perimeter of this shape can be written as:[tex]2(x+8)+2(3x-5)+23 = 126[/tex] (Sides with the same number of dashes are equal in length)
Which becomes:
[tex]2x+16+6x-10+23=126[/tex]
[tex]8x+29=126[/tex]
[tex]8x=97[/tex]
[tex]x= 12.125[/tex]
Since AB = [tex]x+8[/tex], we can substitute to get the length of AB:
[tex]x+8 = 12.125+8[/tex]
[tex]=20.125[/tex]
We can also use substitution to solve for the length of EF:
[tex]3x-5=3(12.125)-5[/tex]
[tex]=31.375[/tex]
Hope this helps :)

Eddie went to Luke Base Air Force Show and brought $55 with him to spend. If admission cost him $5 and sodas were $6.25 each, what is the GREATEST number of sodas, x, Eddie can buy? USE x AS VARIABLE; NO SPACES.
Answer:
8
Step-by-step explanation:
Given that:
Eddie has gone to Luke Base Air Force Show.
Total money available with Eddie = $55
Admission cost = $5
Cost of each soda = $6.25
To find:
The greatest number of sodas that can be bought by Eddie ?
Solution:
Let the greatest number of sodas that can be bought by Eddie = [tex]x[/tex]
Now, the total money spent by Eddie will be equal to the admission fee and the cost for buying the [tex]x[/tex] number of sodas.
Cost for [tex]x[/tex] number of sodas = Cost of one soda multiplied by [tex]x[/tex] = $6.25 [tex]\times x[/tex]
Writing equation as per given statement:
Total money = $55
[tex]55 = 5 +6.25x\\\Rightarrow 6.25x = 55-5\\\Rightarrow 6.25x = 50\\\Rightarrow x = \dfrac{50}{6.25}\\\Rightarrow \bold{x = 8}[/tex]
Therefore, a maximum of 8 number of sodas can be bought.

a council reviews the amount of bedrooms in 40 houses located in the same area. this table shows the information gathered
a) find the modal average of bedrooms
b) work out the mean average of bedrooms
number of bedrooms: frequency:
1 ---------------------------------5
2------------------------------- 10
3 -------------------------------15
4 --------------------------------7
5 --------------------------------3
Answer:
A. 3
B. 2.825
Step-by-step explanation:
Data obtained from the question include:
Number of bedrooms (x) > Frequency(f)
1 >>>>>>>>>>>>>>>>>>>>> 5
2 >>>>>>>>>>>>>>>>>>>> 10
3 >>>>>>>>>>>>>>>>>>>> 15
4 >>>>>>>>>>>>>>>>>>>> 7
5 >>>>>>>>>>>>>>>>>>>> 3
Mode =?
Mean average of bedrooms =.?
A. Determination of the modal average of bedroom.
The mode of a given set of data is the the value with the highest frequency.
Considering the table given in the question above, we can see clearly that 3 has the highest frequency. Hence 3 is the modal average of the bedroom is 3
B. Determination of the mean average of bedroom.
Mean = Σfx / Σf
Σfx = (1×5) + (2×10) + (3×15) + (4×7) + (5×3)
Σfx = 5 + 20 + 45 + 28 + 15
Σfx = 113
Σf = 5 + 10 + 15 + 7 + 3
Σf = 40
Mean = Σfx / Σf
Mean = 113 / 40
Mean = 2.825
Therefore, the mean average of bedroom is 2.825

pls answer,I will also mark the brainest and I will rate 5 out of 5 stars pls show working out
Answer:
the value in the five years is £2,621.44
Step-by-step explanation:
The computation of the value in the five years is given below:
= The value of the second car × (1 - losses percentage)^number of years
= £8,000 × (1 - 0.20)^5
= £8,000 × 0.80^5
= £8,000 × 0.32768
= £2,621.44
Hence, the value in the five years is £2,621.44
We simply applied the above formula so that the correct value could come

1) Which pair of triangles is congruent by Side - Side - Side? *
Please do all of them and don't answer if you don't know thanks in advance :)
best answer will get brainliest and multiple thanks on some of your other answers and this one
Answer:
The fourth pair of triangles.
Step-by-step explanation:
Looking at the diagram for the fourth pair of triangles, we see that two pairs of sides have been marked as having the same length, and the remaining side is shared by the two triangles, hence guaranteeing that side's congruence. Therefore, the fourth pair of triangles is congruent by SSS.
The first pair of triangles are congruent by ASA, due to the middle pair of angles being congruent (vert. opp. ∠s), hence providing the condition for SAS.
The second pair of triangles should be SAS, also known as Side - Angle - Side, due to two angles and one side being marked as congruent, and those two angles surrounding the side marked as congruent.
The third pair of triangles should be SAS, due to them sharing a common side and a pair of sides marked congruent, surrounding the right angle. The reason why it is not RHS is because the pair of hypotenuses are not congruent, hence not fulfilling the condition of Right Angle - Hypotenuse (here!) - Side.
Hope this helped!

Answer:
x = 3
Step-by-step explanation:
You can see that 5x - 7 and 2x + 2 are equal to each other due to the arrows pointing to both angles. Therefore allowing you to set up the following equation..
5x - 7 = 2x = 2
Therefore you can then simplify for the value x where you should get teh value 3.

Write an equation in slope-intercept form of the line shown.
(2,-1) (4,-4)
Answer:
add 44 and 21 and you will get the answer
Answer:
y = -3/2x+2
Step-by-step explanation:
The slope for a slope equation is y = mx+b
Since it's decreasing from left to right the first part of the equation (mx) is -#x. The second part of the equation (+b) will be +2 because the y-intercept is (0,2). If it were a negative # then it would be -7, or -4, or - whatever.
Now you have to find the slope. To find the slope simply do y1-y2/x1-x2 or y2-y1/x2-x1. Let's follow this equation. say that (2,-1) is 1 and (4,-4) is 2.
-1+4/2-4 = 3/-2 = -3/2. The equation would be y = -3/2x +2. Let's check our work by substituting our variables with numbers using the set (2,-1). Pleases tell me if I'm wrong or if this is confusing.

The angles below are supplementary, What is the value of x?
Answer:
x = 12
Step-by-step explanation:
Supplementary angles add up to 180 degrees therefore (6x + 48) and 60 should add up to 180. Like this:
6x + 48 + 60 = 180
Now solve:
6x + 48 + 60 = 180
6x + 108 = 180
6x = 72
x = 12
Therefore, the answer is x = 12.

Answer:
x = 4
y = -7 or (-7, 4)
Step-by-step explanation:
y = -2x + 1
4x + y = 9 replace y in the second equation with (-2x + 1) since y is equal to it
4x + (-2x + 1) = 9 add like terms
2x + 1 = 9 subtract 1 from both sides
2x = 8 divide both sides by 2
x = 4 since y = -2x + 1 replace x with the value we found
y = (-2) × 4 + 1 = -7
