Mathematics

siniylev [52]4 years ago
7 0

Answer:

AB ≈ 7.10

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos65° = \frac{adjacent}{hypotenuse} = \frac{BC}{AB} = \frac{3}{AB}

Multiply both sides by AB

AB × cos65° = 3 ( divide both sides by cos65° )

AB = \frac{3}{cos65} ≈ 7.10 ( to the nearest hundredth )

Lashonda sells beaded necklaces. Each large necklace sells for $5.30 and each small necklace sells for $4.50. How much will she
Tasya [4]

Answer:

$ 37.10 for the large necklaces sold

$ 17.20 for the small necklaces sold

$ 54.30 for the total necklaces sold

Step-by-step explanation:

For each large necklace it costs $5.30 so multiply $5.30 x 7= $37.10 because that's how many she sold. For each small necklace it costs $4.30 so multiply $4.30 x 4= $17.20 because that's how many she sold. If you want the total cost of all the necklaces sold you have to add the two prices together. Please give me the brainliest answer?

:) Hoped this helped!!! Have a good day!!! <3

Which statement describes the graph of y = 7?
Alla [95]

Answer:

b. A horizontal line with no "rise" and infinite "run"

Step-by-step explanation:

since y = 7, y will always equal 7 no matter what the x value is, so it has no rise, or increase in y value. But it doesn't say anything about the x value, so it infinitely increases. The answer is b. A horizontal line with no "rise" and infinite "run"

Please Help!! :D<br><br> Find the value of y.
rjkz [21]

Answer:

y=2\sqrt{2}

Step-by-step explanation:

The Pythagorean theorem is a theorem that can be applied to the sides of a right triangle. Please note that a right angle refers to an angle with a measure of (90) degrees. A box around an angle shows that the angle is a right angle, or has a measure of (90) degrees. The Pythagorean theorem states the following,

a^2+b^2=c^2

Where (a) and (b) are the legs of the triangle, or the side adjacent to the right angle in the right triangle. (c) is the side opposite the right angle, or the hypotenuse of the triangle. One can apply this theorem to the smallest triangle in the diagram to find (y),

a^2+b^2=c^2

Substitute,

(1)^2+(y)^2=(3)^2

Simplify,

(1)^2+(y)^2=(3)^2

1+y^2=9

Inverse operations,

1+y^2=9

y^2=8

y=\sqrt{8}

Take a factor from out of the square root. Remember that a number times itself under the radical is equal to the number. This can be simply stated as the following: (\sqrt{a*a}=a),

y=\sqrt{8}

8=2*2*2

y=\sqrt{8}

y=\sqrt{2*2*2}

y=2\sqrt{2}
