Answer:

x = -5

Step-by-step explanation:

x + y = 5 can be also written as 3x + 3y = 15 by times 3 on both side, let it be equation (1), then let 2x + 3y = 20 be equation (2), then use equation (2) - (1), can get (2x - 3x) + (3y - 3y) = 20 - 15 ---> -x = 5, then x = -5.

Answer:

is that the whole math question? I need a number after the < to solve this

Answer:

x = 31 and y= 11

Step-by-step explanation:

Since sum f angles on a straight line is 180°, hence;

2x+8+3x+17 = 180

Collect like terms

5x+25 = 180

5x = 180-25

5x = 155

x = 155/5

x = 31°

Similarly;

3x+17+5y+15 = 180

Substitute x = 31 into the equation

3(31)+17+15+5y = 180

93+32+5y = 180

125+5y =180

5y = 180-125

5y = 55

y = 55/5

y = 11°

Hence x = 31 and y= 11

Answer:

240.6 ft is your answer of your question.

Answer:

Step-by-step explanation:

to find x we will use cos function

[tex] \quad \: \cos( \theta) = \dfrac{adj}{hypo} [/tex]

substitute the value of [tex]\theta[/tex] and adj:

[tex] \quad \: \cos( {67}^{ \circ} ) = \dfrac{94}{x} [/tex]

cross multiplication:

[tex] \quad \: x\cos(67^{\circ})= 94 [/tex]

divide both sides by cos(67°) :

[tex] \quad \: \dfrac{x \cos( {67}^{ \circ} ) }{ \cos( {67}^{ \circ} ) } = \dfrac{94}{ \cos( {67}^{ \circ} ) } \\ \therefore \: x = 240.6[/tex]

Answer:

m<AEB = 46°

Step-by-step explanation:

Given:

Arc AD = 161°

Arc BC = 107°

Required:

m<AEB

Solution:

Vertex angle = ½(sum of intercepted arcs) => Theorem for angle inside a circle and its intercepted arcs)

This:

m<AED = ½(AD + BC)

m<AED = ½(161 + 107) => Substitution

m<AED = ½(268) = 134°

✔️m<AEB = 180° - m<AED => Linear pair theorem

m<AEB = 180° - 134° => substitution

m<AEB = 46°

The ladder laying against the wall will create a right triangle.

The side lengths will be 18 and 24 and you will solve for the hypoteneuse which will be the length of the latter.

You can use the pythagorean theorm so

[tex]a^{2} +b^{2} =c^{2}[/tex] so you plug in the values

[tex]18^{2}+24^{2} =c^{2} \\324+576=c^{2} \\900=c^{2} \\\sqrt{900} =\sqrt{c^{2} } \\30=c[/tex]

Answer: c=4

Step-by-step explanation:

c^2+3^2=5^2

c^2+9=25

c^2=16

c=4

Hence, the other leg if necessary round to the nearest tenth is [tex]4cm[/tex].

What is the triangle?

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry.

[tex]H^2=B^2+P^2[/tex]

Here given that,

One of the legs of a right triangle measures [tex]3[/tex] cm and it's hypotenuse measure [tex]5[/tex] cm

Let the base of triangle is [tex]x[/tex].

So,

[tex]H^2=B^2+P^2\\\\(5)^2=x^2+(3)^2\\\\25=x^2+9\\\\25-9=x^2\\\\16=x^2\\\\x=4[/tex]

Hence, the other leg if necessary round to the nearest tenth is [tex]4cm[/tex].

Do you have a diagram to follow?

It will much help, and easier for answering.

The radius of the other similar circle is, 6 inches

In mathematics, the circle is a two dimensional rounded figure which has no corner edges.

Standard form = (x - a)² + (y - b)² = r²

Angle = Arc / Radius

Given that,

The two arc lengths for the circles are equal

One circle has a radius of 8 inches and a shaded sector with an angle measure of 90 degrees

The second circle has a shaded sector with an angle measure of 120 degrees

The radius of second circle = ?

α = 90°

It is known that,

π radian = 180°

1°  = π/180 radian

Now,

α = 90 × π/180

   =  π/2

β  = 120°

   =  120 × π/180

   =   2π/3

In Circle 1,

Angle = Arc / Radius

π/2 = Arc/8

Arc = 4π

In both the circles, length of arc is same,

In Circle 2,

Angle = Arc / Radius

2π/3  = 4π/Radius

Radius = 6

Thus, the radius of second circle is 6 inches

Answer:

1,960,000Joules

Step-by-step explanation:

Gravitational Potential Energy is expressed as;

GPE = mgh

m is the mass

g is the acceleration due to gravity

h is the height

Given

m = 1000kg

h = 200m

g = 9.8m/s

Substitute;

GPE  = 1000 * 9.8 * 200

GPE = 9800 * 200

GPE = 1,960,000Joules

Hence the GPE of the balloon is 1,960,000Joules

Answer:

The value is 0.025

Step-by-step explanation:

We get the z-score that is equal to the given value

Mathematically we have this as:

z-score = (x-mean)/SD

x = 93

mean =79

SD = 7

So we have the z-score as;

z-score = (93-79)/7 = 14/7 = 2

So we want to calculate the probability equal to the calculated z-score value of 2

Using the standard normal distribution table, we have this value as;

1 - 0.975= 0.025

Answer:

Step-by-step explanation:

base b = 2 in

slant height L = 7 in

lateral area = 4·½bL = 4·½·2·7 = 28 in²

base area = b² = 4 in²

surface area = 28+4 = 32 in²

If b = 14 and L = 49:

lateral area = 4·½·14·49 = 1372 in²

base area =  196 in²,

and surface area = 1372+196 = 1568 in²

The surface area has multiplied by 49.
