Answer:
[tex]\boxed {\boxed {\sf A. \ 18}}[/tex]
Step-by-step explanation:
The two angles are inside a right angle. The small box signifies a right angle/ 90° angle.
Therefore, the sum of the angle measures must equal 90. We can set up an equation.
[tex]56+(x+16)=90[/tex]
Combine the like terms on the right side. The 2 constants: 56 and 16 can be added.
[tex](56+16)+x=90\\[/tex]
[tex]72+x=90[/tex]
Since we are solving for x, we must isolate the variable. 72 and x are being added. The inverse of addition is subtraction, so subtract 72 from both sides.
[tex]72-72+x=90-72[/tex]
[tex]x=18[/tex]
x is equal to 18 and choice A is correct.

Answer:
Step-by-step explanation: ..............
Find the value of each variable
Answer:
m∠P = m∠Q = m∠R = 60º
Step-by-step explanation:
Because each of the sides are congruent, the angles are congruent. A triangle must add up to 180º, so when you divide 180 by 3, you get 60. Therefore, each angle is 60º.
Answer:
angle P = 60
angle Q = 60
angle R = 60
Step-by-step explanation:
The triangle in the picture is an equilateral triangle. This means that all angles are the same.
Since all triangles have the interior angle of 180, simply take 180 and divide it by 3:
⇒ 180 ÷ 3
⇒ 60
All three angles are 60 degrees
You invested $3000 between two accounts paying 5% and 8% annual interest, if the total interest earned for the year was $210 how much was invested at each rate
Given:
Total amount invested = $3000
Rate of annul interest on investments are 5% and 8%.
Total interest earned for the year = $210
To find:
The amount invested at each rate.
Solution:
Let the amount invested at 5% be [tex]\$x[/tex] and the amount invested at 8% be [tex]\$(3000-x)[/tex].
Total interest earned for the year = $210
It means. 5% of [tex]x[/tex] + 8% of [tex](3000-x)[/tex] = 210
[tex]x\times \dfrac{5}{100}+(3000-x)\times \dfrac{8}{100}=210[/tex]
Multiply both sides by 100.
[tex]5x+(3000-x)8=21000[/tex]
[tex]5x+24000-8x=21000[/tex]
[tex]-3x=21000-24000[/tex]
[tex]-3x=-3000[/tex]
Divide both sides by -3.
[tex]x=1000[/tex]
Now,
[tex]3000-x=3000-1000[/tex]
[tex]3000-x=2000[/tex]
Therefore, the amount invested at the rate of 5% is $1000 and the amount invested at the rate of 8% is $2000.
Write the polynomial in descending order: 4x + 3x^2 - 1
Group of answer choice
A. 3x^2 + 4x - 1
B. 1 - 4x + 3x^2
C. -1 + 3x^2 + 4x
D. 4x + 3x^2 - 1
Answer:
3x^2+4x+1
Step-by-step explanation:
Given the polynomial function 4x + 3x^2 - 1
Rearranging in descending order means that we are to arrange the degree power from the highest to the lowest.
The term with the highest degree is 3x^2
Followed by 4x
Then the constant 1
Adding according to the descending powers
The polynomial in descending order will be 3x^2+4x+1

Could you guys please solve these equations?
12x-17 = 6x+7 solve for x
-8b+1 = -5(b + 4) solve for b
350+10(n-7) = 630+2(n-15) solve for n
thank you
Answer:
x = 4
b = 7
n = 40
I hope this helps!!!
Step-by-step explanation:
1) 12x-17 = 6x+7
+17 +17
*do this because you want to get all of the variables to one side and all of the constants to one side*
12x = 6x + 24
-6x -6x
6x = 24
*divide by 6 to get x alone, so you 24/6 = 4*
x = 4
2) -8b+1 = -5(b+4)
*must multiply -5 by everything in the parenthesises*
-8b+1 = -5b-20
-1 -1
-8b= -5b-21
+5b +5b
-3b = -21
b = 7
3) 350+10(n-7) = 630+2(n-15)
350+10n-70 = 630+2n-30
*combine like terms on both sides of the equation*
280+10n = 600+2n
-280 -280
10n = 320+2n
-2n -2n
8n = 320
n = 40
A circle has a circumference of 34 54 cm. What is the area of the circle to the nearest whole centimeter? Use 3.14
A. 95 cm B. 11 cm С 108 cm2 D 380 cm
Answer:
9498.5 mStep-by-step explanation:
We know that the Circumference = 3454 cm
And we also know that the formula for the Circumference of Circle is,
[tex]2\pi \times r[/tex]
So we can put the equation this way,
[tex]3454 = 2\pi \times r[/tex]
So we can solve for 'r'
[tex]3454 = 2 \times 3.14 \times r \\ 3454 = 6.28r \\ r = \frac{3454}{6.28} \\ r = 550[/tex]
Now we have radius and we can solve for the area of the circle,
[tex]\pi \times {r}^{2} [/tex]
[tex]3.14 \times 550 \times 550 \\ = 949850[/tex]
We can convert this to meter,
9498.5 m
I am not sure if this is correct just let me know thanks :)

Answer: 152 I think
Step-by-step explanation:
La ecuación de la recta que pasa por los puntos (2,-1) y (1,-5) es:
y= 4x+9
y= 4x-9
y= x-9
ninguna de las anteriores
Given:
A line passes through the points (2,-1) and (1,-5).
To find:
The equation of the line.
Solution:
If a line passes through the two points, then the equation of the line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
The line passes through the points (2,-1) and (1,-5). So, the equation of the line is
[tex]y-(-1)=\dfrac{-5-(-1)}{1-2}(x-2)[/tex]
[tex]y+1=\dfrac{-5+1}{-1}(x-2)[/tex]
[tex]y+1=\dfrac{-4}{-1}(x-2)[/tex]
[tex]y+1=4(x-2)[/tex]
Using distributive property, we get
[tex]y+1=4(x)+4(-2)[/tex]
[tex]y+1=4x-8[/tex]
Subtract 1 from both sides.
[tex]y+1-1=4x-8-1[/tex]
[tex]y=4x-9[/tex]
Therefore, the correct option is B.

A tree struck by lightning broke at a point 12 feet above the ground. What was the height of the tree to the nearest tenth of a foot., 12 squared + 39 squared = ??
Answer:
52.8 feets
Step-by-step explanation:
From the diagram :
The height of tree woulb be :
Height above the ground (at breakpoint) + hypotenus
Hypotenus, h cab be obtained using Pythagoras rule :
h² = opp² + adj²
h² = 39² + 12²
h² = 1665
h = sqrt(1665)
h = 40.804 feets
Height of tree to the nearest tenth ;
40.804 feets + 12 feets
= 52.804 feets
= 52.8 feets

An airplane is flying out an altitude of approximately 2 miles above ground level. The pilot sites a landmark at the angle of depression of 11°. One minute later the pilot sides the same landmark and an angle of depression of 18°. To the nearest 10th of a mile how far did the plane fly in that minute?
Answer:
0.3 miles
Step-by-step explanation:
Using trigonometry : d
Tanθ = opposite / Adjacent
Tan 11 = d1 / 2
2tan11 = d1
0.3887606 miles = d1
Tanθ = opposite / Adjacent
Tan 11 = d2 / 2
2tan18 = d2
0.6498393 miles = d2
d2 - d1 = Distance flown within the minute
0.6498393 - 0.3887606 miles
= 0.2610787 miles
= 0.3 miles

Which angle is complementary to DFE? Pls answer
Answer:
<DFA
Step-by-step explanation:
When combined (<DFA and <DFE), they'll form 90 degrees which will make them complementary
Answer:
Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees. If two angles are complementary then they will add up to be 90, or inversely, if two angles add up to be 90, then they are complementary. If you know one acute angle, you can calculate its complementary angle by subtracting 90 and the angle. When the sum of two angles is equal to 90 degrees, they are called complementary angles. For example, 30 degrees and 60 degrees are complementary angles.
The complement of −135° is the angle that when added to −135° forms a right angle (90° ).
