Find the length of BC.
Explain how you got it, please!
Thanks!
Answer:
BC = 30.73
Here,
[tex]\sf \frac{AB}{BQ} = \frac{CD}{DQ}[/tex]
so first solve for QD
[tex]\sf \hookrightarrow \frac{32}{15} = \frac{19.2}{DQ}[/tex]
[tex]\sf \hookrightarrow 32(DQ)} =19.2(15)[/tex]
[tex]\sf \hookrightarrow 32(DQ)} =288[/tex]
[tex]\sf \hookrightarrow DQ =9[/tex]
Hence, QD = 9Now! using Pythagoras theorem,
CD² + BD² = BC²19.2² + (9+15)² = BC²BC = √368.64+576BC = 30.73499634BC = 30.73 ( rounded to nearest hundredth )Answer:
BC = 30.7 units (nearest tenth)
Step-by-step explanation:
As ∠AQR = ∠CQR then ∠AQB = ∠CQD
This means that ΔABQ ~ ΔCDQ
Therefore, the side lengths of two similar triangles are proportional.
[tex]\begin{aligned} \sf \dfrac{AB}{CD} & =\sf \dfrac{BQ}{QD}\\\sf \implies \dfrac{32}{19.2} & =\sf \dfrac{15.0}{QD}\\\sf \implies QD & = \sf 9 \end{aligned}[/tex]
Pythagoras' Theorem: [tex]\sf a^2+b^2=c^2[/tex]
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
Given:
a = BD = BQ + QD = 15 + 9 = 24b = CD = 19.2c = BCSubstituting values into the formula:
[tex]\begin{aligned}\sf 24^2+19.2^2 & = \sf BC^2\\\sf BC^2 & = \sf 944.64\\\sf BC & = \sf \pm\sqrt{944.64}\\\sf BC & = \sf 30.7 \ (nearest \ tenth)\end{aligned}[/tex]

What is the equation of the blue line?
Answer:
y=2x+3
Step-by-step explanation:
Because the y-intercept starts at 3 and it goes up by 2 and to the side 1 so it would be y = 2x +3
Answer: y = 2x + 3
Step-by-step explanation:
We will write the equation in slope-intercept form.
y = mx + b
The slope can be found with "rise over run" since we have clear points on the graph.
Start at (0, 3), count up 2 units, and count one unit to the right. This gives us a slope of positive 2.
Rise / run = 2 / 1 = 2
The "b" value is where the line hits the y-axis. It hits the y-axis at y-coordinate 3, so our y-intercept is positive 3.
Final equation:
y = 2x + 3

If m∠4 = 90°, find the m∠5 and m∠3.
Answer:
∠5 = 90°
∠3 =90
Step-by-step explanation:
∠4 + ∠5 = 180 {Linear pair}
90 +∠5 = 180
∠5 = 180 - 90
∠5 = 90°
∠3 = ∠4 {Verically opposite angles}
∠3 = 90°

What is the equation of the circle pictured?
Explain your reasoning.
Answer:
(x+2)^2 + (y-4)^2 = 4^2
Step-by-step explanation:
A circle is x^2 + y^2 = 1 , where r = 1
The radius of that circle looks to appear to be r = 4.
x^2 + y^2 = 4^2
Transition that circle origin from (0,0) to (-2,4)
The origin is (-2,4) which mean h = -2 left and k = 4 up.
(x-h)^2 + (y-k)^2 = 4^2
(x-(-2))^2 + (y-4)^2 =4^2
Two sides of a triangle are 8 inches and 12 inches long each. Which of the following could be the length of the third side that would form a triangle?

We use the BODMAS method to solve the given questions.
Solve the Bracket then Divide Multiply Add and Subtract
1. 32÷4×(16×1/2) - 2
= 32÷4 × ( 8 ) - 2
= 8 × 8 - 2 = 64 - 2 = 62
2. 20 ÷ (5×2/5) + 3
= 20 ÷ (2) + 3 = 20 ÷ 2 + 3
= 10 + 3 = 13
3. 1/2 ×(6×4) ÷ 3 + 2
= 1/2 × 24 ÷ 3 + 2
= 1/2 × 8 + 2
= 4 + 2 = 6
4. 2 (6÷2+8) - 4
= 2 (3+8) - 4
= 2 × 11 - 4
= 22 - 4
= 18

Nate surveyed 90 students at his school about their favorite class. Based on the graph, how many of the 630 students in the school would be expected to say their favorite class is Reading or Math?
Using proportions, it is found that 420 students in the school would be expected to say their favorite class is Reading or Math.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, out of 90 students, 20 + 40 = 60 students prefer reading or math. How many do out of 630? Thus, the rule of three is given by:
60 prefer reading of math - 90 students.
n prefer reading of math - 630 students.
Applying cross multiplication:
90n = 630 x 60
n = 630 x 60/90
n = 7 x 60
n = 420
420 students in the school would be expected to say their favorite class is Reading or Math.

what is the quotient of 1,224 divided by 9
Answer:
136Step-by-step explanation:
Simply divide the numbers, the result is the quotient
1224/9 = 136The quotient of the given expression when 1,224 divided by 9 is 136.
The quotient is defined as the number obtained on dividing a number with some number.
The number left after the division is called as the remainder.
Example: When 37 is divided by 5, the quotient is 5 and the remainder is 2.
The quotient of the following expression can be calculated as:
When 1224 is divided by 9, it gets divisible in 136 times completely, leaving no remainder.
So, it can be said that 136 is the quotient when 1,224 divided by 9.
