Answer:
=78 degrees
Step-by-step explanation:
complementary angles add up to 90 degrees
A + B = 90
3x + 9 + x - 11 = 90
3x + x + 9 - 11 = 90
4x - 2 = 90
collect like valuables
4x = 90 + 2
4x = 92
x =23
angle A = 3x + 9
= (3 x 23) + 9
= 69 + 9
= 78

Mrs. Santos baked 25 cookies. 3 fifths of the cookies were oatmeal. How many oatmeal cookies did Mrs. Santos bake?
Answer: 15 oatmeal cookies.
Step-by-step explanation:
There were 25 cookies baked.
Out of these, 3/5 are oatmeal cookies.
The amount of actual oatmeal cookies is:
= fraction of oatmeal cookies * total number of cookies
= 3/5 * 25
= 75 / 5
= 15 oatmeal cookies.

HURRY WILL MAKE BRAINLEST! Given: sin(18m-12)=cos(7m+2), find the value of m.
Answer:
m = 4
Step-by-step explanation:
In order for this equation to be true, the angles must be complementary.
So, 18m- 12 + 7m + 2 = 90
25m - 10 = 90
25m = 100
m = 4

Answer: [tex]\sqrt{5} + \sqrt{3} + 10 + 2\sqrt{15}[/tex]
Step-by-step explanation:
[tex]\frac{2+4\sqrt{5} }{\sqrt{5}-\sqrt{3} }[/tex]
You need to multiply by the conjugate
To find the conjugate, first remember:
(a+b)(a-b) = a^2 - b^2 (if a and b are sqrts, this will eliminate the square roots, rationalizing the denominator)
You have √5 - √3 as the denominator
You should multiply by √5 + √3
(This will eliminate the sqrts)
Remember to multiply both the numerator and denominator
[tex]\frac{2+4\sqrt{5} }{\sqrt{5}-\sqrt{3} } = \frac{2+4\sqrt{5} }{\sqrt{5}-\sqrt{3} } * \frac{\sqrt{5}+\sqrt{3} }{\sqrt{5}+\sqrt{3}}[/tex]
Now simplify
[tex]\frac{2+4\sqrt{5} }{\sqrt{5}-\sqrt{3} } * \frac{\sqrt{5}+\sqrt{3} }{\sqrt{5}+\sqrt{3}} = \frac{(2+4\sqrt{5})(\sqrt{5}+\sqrt{3})}{(\sqrt{5}-\sqrt{3})(\sqrt{5}+\sqrt{3})} = \frac{2\sqrt{5}+2\sqrt{3}+20+4\sqrt{15}}{5-3} = \sqrt{5} + \sqrt{3} + 10 + 2\sqrt{15}[/tex]
find the length of the bold arc. Round your answer to the nearest tenth.
Answer:
The length of the bold arc is approximately 13.4 mi
Step-by-step explanation:
The radius of the circle having the arc, r = 17 mi
Therefore, the circumference of the circle, 'C', is given as follows;
C = 2·π·r
∴ C = 2×π×17 = 34·π
The angle subtended by the arc = 45°
The sum of the angles at the center of the circle = 360°
By similarity, the ratio of the length of the bold arc to the circumference of the circle = The ratio of the angle subtended by the arc to the sum of the angles at the center of the circle
Mathematically, we have;
[tex]\dfrac{The \ arc \ length}{C} = \dfrac{\theta}{360^{\circ}}[/tex]
Therefore, we get;
[tex]\dfrac{The \ arc \ length}{34 \cdot \pi} = \dfrac{45 ^{\circ}}{360 ^{\circ}} = \dfrac{1}{8}[/tex]
[tex]{The \ arc \ length}{} = \dfrac{1}{8} \times 34 \cdot \pi = 4.25 \cdot \pi[/tex]
The length of the bold arc = 4.25·π mi ≈ 13.4 mi (by rounding off the answer to the nearest tenth).

The Ski Club sells 180 keychains. A third of the keychains sold are blue and 1/6 of the remaining keychains are white. The rest of the keychains are red. How many keychains are red?
Answer:
Step-by-step explanation:
blue = ⅓×180 = 60
180-60 = 120 are not blue.
white = ⅙×120 = 20

In ΔTUV, t = 320 inches, u = 360 inches and ∠V=81°. Find the area of ΔTUV, to the nearest square inch.
Answer:
[tex]Area = 56892in^2[/tex]
Step-by-step explanation:
Given
[tex]\triangle TUV[/tex]
[tex]t = 320in[/tex]
[tex]u = 360in[/tex]
[tex]\angle V = 81^\circ[/tex]
Required
Calculate the area
Given two sides and a middle angle, the area of a triangle is:
[tex]Area = \frac{1}{2}ab*sinC[/tex]
In this case, it is:
[tex]Area = \frac{1}{2}tu*sinV[/tex]
[tex]Area = \frac{1}{2}*320*360*sin(81)[/tex]
[tex]Area = \frac{1}{2}*320*360*0.9877[/tex]
[tex]Area = 56891.52[/tex]
[tex]Area = 56892in^2[/tex] --- approximated

When Javier is 2, Arianna is 5. When Javier is 3, Arianna is 6.
When Javier is 8, Arianna will be 11. When Javier is 20, Arianna is 23.
Complete the table. Circle the letter of the equation that relates the age
of Arianna, y, to the age of Javier, x.
Answer:
Step-by-step explanation:
Arianna will always be 3 years older than Javier no matter how old he gets.
The table is given below.
The equation that relates the age of Arianna y to the age of Javier x is
y = x + 3
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
We can use the given information to complete the table as follows:
Javier(x) Arianna (y)
2 5
3 6
8 11
20 23
Now,
The equation that relates the age of Arianna, y, to the age of Javier, x.
We have,
y = mx + b, where m is the slope and b is the y-intercept.
We can use the first two points (2, 5) and (3, 6) to find the slope.
m = (6 - 5)/(3 - 2)
m = 1
Now,
The y-intercept,
(2, 5) = (x, y)
y = mx + b
5 = 1(2) + b
b = 3
Therefore,
The equation that relates the age of Arianna y to the age of Javier x is
y = x + 3
