Answer:

x=8

Step-by-step explanation:

  1. Pythagorean Theorem Formula: a^2+b^2=c^2
  2. Let a be x, let b be 6, and let c be 10.
  3. Plug x, 6, and 10 into the equation - x^2+6^2=10^2
  4. Simplify 6^2 and 10^2 - x^2+36=100
  5. Subtract 36 from both sides - x^2=64
  6. Take the square root of x^2 and 64 to get x by itself - x=8

A cafe only sells two types of sandwiches, turkey and steak. The cafe charges $4 for turkey sandwiches and $6 for steak sandwich
Zolol [24]
\left \{ {{T+S=925} \atop {4T+6S=4524}} \right.  \\ S=925-T \\ 4T+6(925-T)=4524 \\ 4T+5550-6T=4524 \\ -2T+5550=4524 \\ -2T=-1026 \\ T=513
So they sold 513 turkey sandwiches

In ABC with the right angle at vertex C, sin(b)= (26)/8. What is sin(a)?
Marat540 [252]

Answer:

We can use the Pythagorean theorem and properties of sines, cosines, and tangents to solve the triangle, that is, to find unknown parts in terms of known parts.

Step-by-step explanation:

Pythagorean theorem:   a2 + b2 = c2.

Sines:   sin A = a/c, sin B = b/c.

Cosines:   cos A = b/c, cos B = a/c.

Tangents:   tan A = a/b, tan B = b/a.

Last month, he sold 50 chickens and 30 ducks for $550. This month, he sold 44 chickens and 36 ducks for $532
IgorC [24]
The answer is chicken $8, duck $5

x - the cost of a chicken
y - the cost of a duck

<span>he sold 50 chickens and 30 ducks for $550: 50x + 30y = 550
</span><span>he sold 44 chickens and 36 ducks for $532: 44x + 36y = 532

</span>50x + 30y = 550                divide by 10
44x + 36y = 550                 divide by 4
______________
50x/10 + 30y/10 = 550/10
44x/4 + 36y/4 = 532/4
______________
5x + 3y = 55                                    Multiply by (-3)
11x + 9y = 133
______________
5x * (-3) + 3y * (-3) = 55 * (-3)
11x + 9y = 133
______________
-15x - 9y = -165
11x + 9y = 133
______________
Sum up:
-4x + 0y = -32
-4x = -32
x = -32/-4
x = 8


Since 5x + 3y = 55  and x = 8, then:
5 * 8 + 3y = 55
40 + 3y = 55
3y = 55 - 40
3y = 15
y = 15/3
y = 5

It is given that,

Miguel made 80 on his Math test. He made 95 in last week's Math test.

We need to find the percent change on his scores. It can be calculated as follows :

\%=\dfrac{\text{original score-initial score}}{\text{original socre}}}\times 100\\\\\%=\dfrac{95-80}{95}\times 100\\\\\%=15.78\%

So, there is a percent change of 15.78%.
