Answer: 12

Step-by-step explanation:

By the corresponding angles theorem, [tex]4x-5=97-2x \longrightarrow x=17[/tex].

So, this means that [tex]97-2x=63[/tex].

Now, by the same-side interior angles theorem, we know that [tex]10y-3+63=180 \longrightarrow y=\boxed{12}[/tex]

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

Answer:

∠A = 22°

Step-by-step explanation:

complementary angles is either of two angles whose sum is 90°

∠A + ∠B = 90°

m∠B = 68°

∠A + 68° = 90°

subtract 68 from both sides

∠A + 68° - 68 = 90° - 68

∠A = 22°

Answer:

22°

Step-by-step explanation:

M<A+M<B= 90° ( complementary angles)

M<A+ 68° = 90°

M<A = 90-68= 22°

M<A= 22°

Answer:

Rectangle:

A rectangle has 4 interior 90° angles and 2 sets of parallel sides (11.2,11.2 and 9.6,9.6) so therefore it was correctly named

Rhombus:

Opposite angles in a rhombus are equal (102° and 102° and 78° and 78°)

and has two pairs of parallel sides; one of these pairs being diagonal lines (13.2,13.2)

Answer:

60 ft²

Step-by-step explanation:

in a cube all sides are congruent so you take one measurement and multiply it by the number of sides, so you do 12 × 6 equals 60.

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:

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 = 20

Step-by-step explanation:

     Let's add what it tells us to the picture. See attached. Since the angles boxed in green are congruent, we can set them equal to each other and solve for x.

3x - 10 = 2x + 10

3x - 20 = 2x

-20 = -x

20 = x

x = 20

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

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°.

[tex]w=\dfrac{8x^2-2y}{y}[/tex]

Step-by-step explanation:

[tex]\textsf{When}\:\dfrac{2x^2}{y}=\dfrac{w+2}{4}\:\textsf{is solved for}\:w,\:\textsf{one equation is}\:w=\dfrac{8x^2}{y}-2[/tex]

Which of the following is an equivalent to find w?

[tex]w=\dfrac{8x^2+2y}{y}[/tex]

[tex]w=\dfrac{8x^2-2y}{y}[/tex]

[tex]w=8x^2-3y[/tex]

[tex]w=8x^2-y[/tex]

[tex]\textsf{Given}: \quad w=\dfrac{8x^2}{y}-2[/tex]

[tex]\implies w=\dfrac{8x^2}{y}-\dfrac{2y}{y}[/tex]

[tex]\implies w=\dfrac{8x^2-2y}{y}[/tex]

The solution for w is [tex]w=\frac{2(4x^2-y)}{y}[/tex] in the equation [tex]\frac{2x^2}{y} = \frac{w+2}{4}[/tex] obtained by isolating the variable term w.

The given equation is[tex]\frac{2x^2}{y} = \frac{w+2}{4}[/tex]

We need to solve for w:

To do this we have to isolate the term with w.

Apply cross multiplication:

[tex]8x^2 = y(w+2)[/tex]

Divide both sides by y:

[tex]\frac{8x^2}{y}=w+2[/tex]

Subtract 2 from both sides:

[tex]\frac{8x^2}{y}-2=w[/tex]

[tex]\frac{8x^2-2y}{y}=w[/tex]

[tex]\frac{2(4x^2-y)}{y}=w[/tex]

Hence, the solution for w is [tex]w=\frac{2(4x^2-y)}{y}[/tex].

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 :)
