Answer:

t(3u)

Step-by-step explanation:

First we have to triple (x3) u, which is what gets us 3u.  Then we multiply that result by t.  

This gives us:  t(3u)

Remember, this problem is asking for you to write an expression, not and equation.  That is why there is not an equal sign included in the answer.

Answer: m=-9/10; d=13.45

Step-by-step explanation:

To find the slope, you would use the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]. We plug in the given points and solve.

[tex]m=\frac{9-0}{0-10} =\frac{9}{-10} =-\frac{9}{10}[/tex]

Now, we know that slope is -9/10.

To find the distance between the points, we use the distance formula.

Distance formula: [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]d=\sqrt{(0-10)^2+(9-0)^2}[/tex]             [parenthesis]

[tex]d=\sqrt{(-10)^2+(9)^2}[/tex]                       [exponent]

[tex]d=\sqrt{100+81}[/tex]                               [add]

[tex]d=\sqrt{181}[/tex]

[tex]d=13.45[/tex]

Now, we know the distance is approximately 13.45.

Answer:

The Answer Is: m∠ABD = m∠ABC

Step-by-step explanation:

I just took the test

A line is a one-dimensional shape that is straight. The statement that must be true about the given condition is A, m∠ABD=m∠ABC.

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely.

Given that a horizontal line has points D, B, C. A line extends vertically from point B to point A. Also, Ray BA bisects ∠DBC. Therefore, the diagram for the given condition can be made as shown below.

Thus, the statement that must be true is m∠ABD = m∠ABC. This is because ∠DBC is a straight line, therefore, its measure will be 180°. And since Ray BA bisects ∠DBC. Therefore, the measure of m∠ABD = m∠ABC = 90°.

Hence, the statement that must be true about the given condition is A, m∠ABD = m∠ABC.

Answer:

1/10 =0.1 in decimal

Step-by-step explanation:

Answer:

$0.25 per donut.

Step-by-step explanation:

So, we know that Jamie spends the same amount of money each morning.

On Sunday, he spent $1.25 on a newspaper and bought 2 donuts.

On Monday, he spent $0.50 on a newspaper and bought 5 donuts.

Since he spend the same amount of money each morning, we can say that:

[tex]1.25+2x=0.5+5x[/tex]

Where x represents the cost per donut.

So, to find the cost of a donut, we need to solve for x.

So, let's try to isolate the x. Subtract 2x from both sides:

[tex](1.25+2x)-2x=(0.5+5x)-2x[/tex]

The left side cancels. Subtract on the right:

[tex]1.25=0.5+3x[/tex]

Now, let's subtract 0.5 from both sides:

[tex]0.75=3x[/tex]

To find x, divide both sides by 3:

[tex]x=0.75/3[/tex]

Divide:

[tex]x=0.25[/tex]

Therefore, each donut cost $0.25.

And we're done!

1/2 is the constant of proportionality because no matter what y or x is equal to, 1/2 will not change.

Answer:

A) ∠ABD is a right angle.

E) m∠ABD = 90°

Step-by-step explanation:

just took the test

∠ABD is a right angle and ∠ABD = 90° will be correct for the given angles.

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

The angle is the measurement of the angular distance for example for linear motion we have a meter inch but for angular rotation, we don't have the measurement so the angle is useful to measure the angular rotation.

Given that,

Angle A B D is a right angle.

The right angle is a 90-degree angle.

So,

m∠ABD = 90°

Hence "∠ABD is a right angle and ∠ABD = 90° will be correct for the given angles".

Answer:

The undefined terms needed to define parallel lines are 'lines' and 'points. ' In geometry, there are three undefined terms: points, lines

Step-by-step explanation:

Answer:

Say you have to find two consecutive integers whose sum is 89. How do you go about this problem? You first take a variable, say x, the value of which is unknown to you. Next, you are supposed to take another number. Since the problem requires you to use two consecutive integers, the integer next to x will be (x + 1). Now as per the problem, the sum of x and (x+1) is 89. We represent this in the form of an equation: x + (x + 1) = 89. Solving this equation we get x as 44 and the next integer (x + 1) as 45, the sum of which is 89.

Step-by-step explanation:

Explanation:

Let's say,

(x1,y)  (x2,y2)

are two points in a

xy

plane. We can find the shortest distance between two point by applying the distance formula stated as:

Distance

=√(x2−x1) 2+(y2−y1) 2

So by putting our given points

(x1,y1)=(6,−5) and (x2,y2)=(−1,−4)

in the distance formula, we have:

¯¯¯¯¯¯CD=√(−1−6)2+(−4−(5)2

You need to translate these into a common rate.

feet / second is probably the best one.

Whippet: 50/1 = 50 feet / second.

Ostrich: 40 miles/ hour = 40 *[ 1 hour/3600 sec] * [5280 feet / mile] = 58.67 ft/sec

Giraffe: 1/2 mile / minute * [1 minute/60 sec]*[5280 feet/mile] = 1/2 * 5280/60 = 44 feet/second

Cat: 15 yards / sec [ 3 feet/ yard] = 45 feet / second

Looks like the Ostrich is the fastest.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Charlotte drove 304 miles in 8 hours.

And, She continued at the same rate.

Now,

Since, Charlotte drove 304 miles in 8 hours.

Hence, The speed is,

Speed = Distance / time

          = 304 / 8

          = 38 miles / h

So, For travel 190 miles at same rate;

Time = Distance / Speed

       = 190 / 38

       = 5 hour

Thus, The time to travel 190 miles will be 5 hour.
