Answer:

she spent $1782

Step-by-step explanation:

first we have to find out her total money then minus 990

to get that 990 /5 then multipliedby 6 is 1188

1188 over 3 then times by 7 is 2772

2772 is the total amount of money she had. minus what she had left which is 990 she has spent 1782 dollars

Solve the equations below exactly. Give your answers in radians, and find all
kotegsom [21]

Answer:

See below (along with unit circle attached)

Step-by-step explanation:

sin(t)=-\frac{\sqrt{3}}{2}

t=\frac{4\pi}{3},\frac{5\pi}{3}

cos(t)=\frac{1}{2}

t=\frac{\pi}{3},\frac{5\pi}{3}

It really helps to use the unit circle! I've attached it below for your convenience. Keep in mind that a point on the unit circle is defined by (cos(\theta),sin(\theta)) where \theta is measured in radians.

Please Solve for 3 of them
Furkat [3]

Answer:

13.  b.  4 + 5x = 29; $5.

14.  c.  74 + w = 3w + 6; 34 pounds.

15.  b.  $42.5.

Step-by-step explanation:

13. 4 + 5x = 29

5x = 29-4 = 25

x = 5.

14. 74 + w = 3w + 6

68 = 2w

w = 34.

15. Let x be the money he got last year. Then:

2x + 5 = 90

2x = 85

x = $42.5.

Triangle abc is congruent to triangle xyz. angle a measures 50 degrees angle b measure 2 x plus 40 degrees and angle z measures
Anarel [89]

Because these triangles are congruent, then angle a is the same degree measure as angle x; angle b is the same as y; and angle c is the same as z. We also know that, because of the Triangle Angle-sum Theorem, all the angles of a triangle have to add up to equal 180 degrees. So for us that means that a+b+c(which is also z) = 180. 50 + 2x + 40 + 4x + 8 = 180. Combining like terms we have 6x + 98 = 180. Subbtracting 98 from both sides gives us 6x = 82 and x = 13 2/3
