Answer:

3x/7 + 8/7

Step-by-step explanation:

Answer:

x=18

<1=34

<2=56

Step-by-step explanation:

Step-by-step explanation:

Since the x-intercepts are -20 and 40, the line of symmetry is x = (-20 + 40)/2 = 10.

Now we have y = a(x - 10)² + 30, where a is an unknown constant. We can find a by using an x-intercept point.

=> (0) = a[(40) - 10]² + 30

=> 900a + 30 = 0, a = -1/30.

Hence the rule is y = -(x - 10)²/30 + 30.

Step-by-step explanation:

8/27 because if you think about it 2/3 x 2/3 x 2/3 x 2/3 = 8/27

Answer:

A:  angle A is 90°, angle B is 90°, angle C is 90°, and angle D is 90°

B:  angle A is 80°, angle B is 80°, angle C is 100°, and angle C is 100°

D:  angle A is 60°, angle B is 50°, angle C is 120°, and angle D is 130°

Step-by-step explanation:

The sum of opposite angles of a cyclic quadrilateral is 180°

It must satisfy the following:

A+C=180° and B+D=180°

Only choice A and B and D satisfy.

The correct options are options A, B, and D.

A quadrilateral having all its corners on a circle plus opposite angles' sum is 180° called a cyclic quadrilateral.

A) ∠A =90°

∠B=90°

∠C =90°

∠D =90°

∠A + ∠C = 180°

∠B + ∠D =180°

So, this quadrilateral can come from a cyclic quadrilateral.

B) ∠A =80°

∠B=80°

∠C =100°

∠D =10 0°

∠A + ∠C = 180°

∠B + ∠D =180°

So, this quadrilateral can come from a cyclic quadrilateral.

Similarly, options C, D, and E also can be checked whether they can come from a cyclic quadrilateral or not.

C) Cannot come from a cyclic quadrilateral since ∠A + ∠C =140°≠180°.

D) ∠A + ∠C = 180°

∠B + ∠D =180°

So,  this quadrilateral can come from a cyclic quadrilateral.

E)Cannot come from a cyclic quadrilateral since∠A + ∠C = 170°≠180°.

Therefore, The correct options are options A, B, and D.

Answer:

create a proportion 72/348 = 32/x

Step-by-step explanation:

x = 1682

1682 ÷ 12 = 140.1

The length of the tree’s shadow that will allow the tree to be cut down will be 150.5 inches.

What are ratio and proportion?

A ratio is an ordered set of integers a and b expressed as a/b, with b never equaling 0. A proportional is a mathematical expression in which two things are equal.

A lumber mill needs one more tree cut down that is at least 29 feet long. The person cutting down the tree is 6 feet 2 inches tall.

            29 feet = 348 inches

6 feet 2 inches = 74 inches

Using shadows to determine whether a tree is tall enough, the person stands next to the tree and measures the length of his shadow as 32 inches.

Then the length of the tree’s shadow that will allow the tree to be cut down will be

Let x be the tree’s shadow. Then we have

x / 348 = 32 / 74

x = 150.486

x ≅ 150.5 inches

Answer:

It doesn't make sense

Step-by-step explanation:

Given

Statement: .... at a speed of 35 miles .....

Required

Does it make sense?

In motion, speed is measured in km/h, m/s, miles per hour (depending on context) while distance is measured in km, m or miles.

However, the given statement mention the unit of speed to be miles which is incorrect.

Hence, we can conclude that the statement does not make sense.

A correct statement would be: I drove at a speed of 35 miles per hour .......

Answer:

530.7

Step-by-step explanation:

A circle's area is defined as πr²

You would substitute 13 in for r (the radius) and use 3.14 as your given value for pi, leaving you with this:

3.14×13²

When you calculate this, it should return a value of 530.66, which rounded to the nearest tenth is 530.7

Hence, the temperatures in these other cities are

Orlando is [tex]25[/tex] degree

Salt Lake is [tex]-10[/tex] degree

Minneapolis is [tex]-17[/tex] degree

Fairbanks is [tex]-29[/tex] degree

What is the degree?

A degree, usually denoted by °, is a measurement of a plane angle in which one full rotation is [tex]360[/tex] degrees.

Here given that,

One winter day, the temperature in Houston is [tex]8[/tex] Celsius.

In Orlando, it is [tex]17[/tex] warmer than it is in Houston.

In Salt Lake City, it is [tex]18[/tex] colder than it is in Houston.

In Minneapolis, it is [tex]25[/tex] colder than it is in Houston.

In Fairbanks, it is [tex]12[/tex] colder than it is in Minneapolis.

So, it would be

Orlando = [tex]25[/tex] degree

because [tex]17+8=25[/tex] degree

Salt Lake city [tex]= -10[/tex] degree

because [tex]8-18=-10[/tex] degree

Minneapolis [tex]= -17[/tex] degree

because [tex]8-25=-17[/tex] degree

Fairbanks [tex]= -29[/tex] degree

because [tex]-17-12=-29[/tex] degree

Hence, the temperatures in these other cities are

Orlando is [tex]25[/tex] degree

Salt Lake is [tex]-10[/tex] degree

Minneapolis is [tex]-17[/tex] degree

Fairbanks is [tex]-29[/tex] degree

Answer:

angle Y= 60 degrees

Step-by-step explanation:

angle S + angle Y = 90 degrees because they are complementary

Y = 90 - S

angle S = 4(Y)-210

substitute for Y

S = 4(90 - S) - 210

S = 360 - 4S - 210

reduce

5S = 150

S = 30

Y = 90 - 30 = 60
