Answer:

∠x=41°

Step-by-step explanation:

Supplementary Angles are angles that equal 180°

1. Use the equation

∠x+∠y=180°

2. Fill in the given values

∠x+139°=180°

3. Solve

Subtract 139 from both sides

∠x+139°=180°

      -139° -139°

4. Answer

∠x=41°

Answer:

α=30, β=60

Step-by-step explanation:

we have angles α and β where α + β =90 & β=α+30

this gives us a system of equations that can be solved through substitution

[tex]\alpha +\beta =90\\\beta =\alpha +30[/tex]

substitute to solve for α: α+(α+30)=90

2α+30=90

2α=60

α=30

substitute α to find β:

β=α+30

β=(30)+30 = 60

Answer:

x=6 y=3

Step-by-step explanation:

Isolate x for -x+ 4y = 6: x= -6+ 4y

Substitute x = -6 + 4y

4(-6+ 4y) - 8y = 0

Simplify

-24+ 8y =0

Isolate y for -24 + 8y = 0: y =3

For x = -6+ 4y

Substitute y =3

X= -6+ 4 × 3

Simplify

X=6

The solutions to the system of equations are:

x=6 y=3

Answer:

#9 24 T-Shirts for $168

#10 the diffirence between 30 T-Shirts and 9 T-Shirts is 147

Step-by-step explanation:

so to get the cost (c) for 1 T-Shirt you need to divide 147 by 21

147 ÷ 21 = 7

so c=7

10x7=70

70x3=210

30x7=210

so 30 shirts cost $210

and 9x7=63

so now it is time to do the rest of the math.

210

-63

Answer:

2/9

Step-by-step explanation:

First, square the fraction 5/6 to get 1/2 * 25/36 - 1/8. Next, multiply 1/2 and 25/36 to get 25/72. Finally, subtract 1/8 to get the answer 2/9.

Answer:

2/9

Step-by-step explanation:

=> 1/2 (5/6)^2 - 1/8

=> 1/2 (25/36) - 1/8

=> 25/72 - 1/8

=> make 1/8 to have a denominator of 72.

=> multiply the numerator and denominator by 9/9

=> 1/8 becomes 9/72

soo

=> 25/72 - 9/72

=> 16/72

^the greatest common factor is 8

=> 2/9

2/9 is your answer :)

If the total number of lunch items is 117, there will be 39 hamburgers there

Fractions are written as a ratio of two numbers

Given

Total items = 117

If the ratio of hot dogs to hamburgers is 26:13, then the total hamburgers that are there is given as:

Hamburgers = 13/39 * 117
Hamburgers = 39

This shows that if the total number of lunch items is 117, there will be 39 hamburgers there

The third angle of the triangle will be ∠B = 69°.

The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.

Given that:-

The third angle will be calculated as:-

∠A   + ∠C + ∠B = 180

43  +  68  +  ∠B = 180

∠B = 180 - 43 - 68

∠B = 69°

Therefore the third angle of the triangle will be ∠B = 69°.

Answer:

16x^2 - 9 = 0

(4x)^2 - 3^2 = 0

a^2 - b^2 = (a - b) (a + b)

Hence, (4x - 3) (4x + 3) = 0

Either (4x - 3) = 0 or (4x + 3) = 0

4x = 3 or 4x = -3

x = 3/4 or x = -3/4

Answer:

surface area=2816 m² & volume =205.33m³

Step-by-step explanation:

here

diameter of base (d) -28 m

radius(r) = d/2=14 m

vertical height of cone (h)-48 m

slant height of cone (l)-50 m

surface area (TSA)-?

volume (v)-?

we know

TSA=(pie*r*l)+pie*r*r

=pie*r(l+r)

=22/7* 14(50+14)

=22*2(64)

=22*128

=2816 m²

again

v=1/3 pie*r*r

=1/3*22/7*14*14

=1/3*22*2*14

=205.33 m³
