Latasha needs to run 0.23 minutes more minutes to complete the mile.

What is the speed of a runner?

The speed of a runner is the ratio of the distance covered in a specific time.

Given,

Latasha ran a mile in 7.03 minutes and Erik ran a mile in 6.8 minutes.

Therefore, difference in time = (7.03 - 6.8) minutes = 0.23 minutes.

If Fiona deposited $900 in the bank over 2 years. She earned $60 in

simple interest at the end of the 2 years then 3.33% is the annual

interest rate.

percentage, a relative value indicating hundredth parts of any quantity.

Given that Fiona deposited $900 in the bank over 2 years.

She earned $60 in simple interest at the end of the 2 years.

We have to find the annual interest rate

I=PRT

60=900×2×T

60=1800T

Divide both sides by 1800

T=3.33%

Hence,  the annual interest rate is 3.33%

Answer:

The simplified expression is

2x2+7x−13.

Step-by-step explanation:

Explanation:

Since this isn’t an equation, but rather an expression, it can only be simplified, not evaluated.

So let’s simplify it.

First distribute the

t (x2−1)

⇒3x2−3−(x2−7x+10)

Distribute the negative sign and drop the parentheses

:⇒3x2−3−x2+7x−10

Combine like terms:

Answer: 118 degrees

Step-by-step explanation:

Angles in a triangle add up to 180 degrees.

So...

180 - (42+20) = 118 degrees

Answer:

given,

angles of triangle= 42°, 20° , x(let)

we know,

The sum of interior angles of triangle is 180°

so,

42°+20°+x=180°

62°+x=180°

X=180°-62°

X= 118°

Hence,the other angle is 118°

Answer:Sara hina and Arslan Have RS79.4,RS 72.4 and RS238.2 respectively.

Step-by-step explanation:

Step 1

Let the amount that hina has be x

the amount that sara has be represented as  7+x

and the amount that Arslan have be represented as 3(7+x)

such that the total amount in their wallet which is 390 can be expressed as

x+7+x + 3(7+x)=390

Step 2

Solving

x+7+x +21+3x=390

5x+28=390

5x==390-28

x=362/5=72.4

Hina has RS 72.4

Sara =7+x==72.4+77= RS 79.4

Arslan =3(7+x)=3 x 79.4=RS 238.2

The green object below, is best defined as a Ray named AC.

In geometry, a ray is a part of a line that consists of a single initial point called the endpoint and extends infinitely in one direction. It can be thought of as a half-line, with one end point and the other end extending infinitely.

Rays are named using two points, with the endpoint being mentioned first.

Here, in the figure the green line has one point A and the next C and it is further extending.

Thus, the Green line is a Ray name as ray AC.

Step-by-step explanation:

None of the numbers go to 17

Answer:

1st option. the data set doesn't GO to seventeen

Step-by-step explanation:

look at the number line. I always had trouble with this so I get where your coming from first, look at where the line is touching don't pay attention to the box yet because it's confusing the entire point of this line is to show you that there MAY have been 1 or two people who where at 0 for this data and 1 or two people who were at 15

the point here is that the bulk of the data was 11-14, but because there were less people down lower, the mean of the data is at 13, and the data is bigger (skewed) to the left.

Answer:

he will save $20 and save $20 okay?

Step-by-step explanation:

Answer:

4 months.

Step-by-step explanation:

First you need to subtract the amount Conner spent from the amount Conner had.

We know Conner had $400 and spent $25 at the movies, so 400 - 25 = he has $375

Next, you have to find how much money he has to earn before he can buy the bike again.

We know the bike costs $440 and Conner has $375 so 440 - 375 = $65 needed

Finally we need to determine how many months it will take to earn $65

We know Conner saves $20 a month, and he needs $65, so 65 / 20 = 3.25 But Conner saves $20 a month, so you need to round up to 4 months.

Answer:

We can't see the image of the spinner. So let's solve this in a general way.

Let's assume that the probability of landing on E is:

P(E)

And the same for all the letters, we will have:

P(A), P(B), P(C), P(D).

Then, the probability of the spinner landing on E for the first spin is just P(E).

Now, the probability of landing on either C or D is: P(C) + P(D)

The joint probability, thus, the probability of both events happening is:

P = P(E)*(P(C) + P(D))

Now, if each letter has the same probability (and we have 5 of them)

Then:

P(E) = 0.2

P(C) = 0.2

P(D) = 0.2

Replacing that in the equation we would get:

P = 0.2*(0.2 + 0.2) = 0.2*0.4 = 0.08

Answer:

a) The volume of the box is represented by [tex]V = 21\cdot x - 20\cdot x^{2}+4\cdot x^{3}[/tex].

b) A side length of 0.653 inches leads to the maximum volume of the box: 6.299 inches.

Step-by-step explanation:

a) The volume of the box ([tex]V[/tex]), in cubic inches, is modelled by the equation for the cuboid:

[tex]V = (3-2\cdot x) \cdot (7-2\cdot x) \cdot x[/tex] (1)

Where [tex]x[/tex] is the side length of the cutted square corners, in inches.

[tex]V = (21 - 20\cdot x + 4\cdot x^{2})\cdot x[/tex]

[tex]V = 21\cdot x - 20\cdot x^{2}+4\cdot x^{3}[/tex]

The volume of the box is represented by [tex]V = 21\cdot x - 20\cdot x^{2}+4\cdot x^{3}[/tex].

b) The method consist in graphing the polynomial and looking for a relative maximum. We graph the equation found in a) by means of a graphic tool. We present the outcome in the image attached below. According to this, a side length of 0.653 inches leads to the maximum volume of the box: 6.299 inches.

Answer:

the answer is A because the height is 40 feet and the ground is 26°

Answer: B

The Vertical Angles Theorem states that vertical angles, angles that are opposite each other and formed by two intersecting straight lines, are congruent. This means that 48° should equal (7x+13)°, because they're vertical angles. The equation should appear as 48=7x+13. Subtract 13 on both sides to get. 35=7x. Divide 7 on both sides to result with x=5.

Answer:

The correct answer is B) [68.2, 92.0]

Step-by-step explanation:

This is from usatestprep:

Given a normally distributed random variable X with mean and standard deviation , invNorm (p, , ) = x: P(X < x) = p.Because of the symmetry of the normal distribution about the mean, the bounds of the interval (x1, x2) centered at the mean, such that P(x1 < X < x2) = a arex2 = invNorm (0.5 +a2, , ); x1 = - (x2 - )Here x2 = invNorm (0.5 +0.502, 80.1, 17.7) = 92.04x1 = 80.1 - (92.04 - 80.1) = 68.06Rounded to the nearest tenth, the required interval is [68.1, 92.0].

We can infer here that the inverse tangent is used to find a missing angle measure when we are given the opposite side and the adjacent side.

An inverse tangent is known to be the formula that is used to find an angle of a right-angled triangle when certain sides are given. This is true when opposite and adjacent sides are given.

Thus, to find an angle using inverse tangent, we will have: θ = tan-1[ (opposite side) / (adjacent side) ].
