Matteo spends a total of 38 min exercising. He walks for 6 min to warm up and then runs at a constant rate of 8 min per mile for the rest of the time. Matteo says that he ran 4.75 mi. Is he correct? Explain your reasoning.

Answer: B

Step-by-step explanation:

Step 1: We make the assumption that 152 is 100% since it is our output value.

Step 2: We next represent the value we seek with x

Step 3: From step 1, it follows that 100%=152

Step 4: In the same vein, x%=47.9

Step 5: This gives us a pair of simple equations:

100%=152(1).

x%=47.9(2).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

100%/x%   = 152/47.9

x= 31.5

Answer:

21%

Step-by-step explanation:

The sale price is 21%

He ran for 6/5 miles long.

In maths, to multiply means to add equal groups. When we multiply, the number of things in the group increases. The two factors and the product are parts of a multiplication problem.

Given that, Tyrone run on a 3/5 long track for twice.

3/5*2 = 6/5

Hence, He ran for 6/5 miles long.

Answer:

Consecutive interior angles will be supplementary

Step-by-step explanation:

As we know that a transversal line is a straight line which tends to intersect two or more parallel lines.

Consecutive interior angles are interior angles that are on the same side of the transversal line. Their sum is 180°.

Hence, Consecutive interior angles will be supplementary

For example, let ∠A and ∠B be the two consecutive interior angles.

As the sum of Consecutive interior angles is 180°, hence they are supplementary.

so the equation becomes

∠A + ∠B = 180°

Let suppose <A and <B are both consecutive interior angles.

Let ∠A is 110°, and we have to determine ∠B.

As the sum of Consecutive interior angles is 180°,

110° + ∠B = 180°

∠B = 180° - 110°

     = 70°

so 70° + 110° = 180°

Therefore, Consecutive interior angles will be supplementary

Answer:

Step-by-step explanation:

I have no idea what formula that is you're using but the one I teach in both algebra 2 and in precalculus for continuous compounding is

[tex]A(t)=Pe^{rt}[/tex]

where A(t) is the amount after the compounding, P is the initial investment, ee is Euler's number, r is the interest rate in decimal form, and t is the time in years. If our money doubles, we just have to come up with a number which will be P and then double it to get A(t). It doesn't matter what number we pick to double, the answer will come out the same regardless. I started with 2 and then doubled it to 4 and filled in the rest of the info given with time as my unknown:

[tex]4=2e^{(.062)(t)}[/tex]

Begin by dividing both sides by 2 to get

[tex]2=e^{.062t}[/tex]

The only way we can get that t out of its current position is to take the natural log of both sides. Natural logs have a base of e, so

[tex]ln_e(e)=1[/tex] This is because they are inverses of one another. Taking the natural log of both sides:

[tex]ln2=.062t[/tex] Now divide by .062 to get

t = 11.2 years

Answer:

y = -4x - 6

Step-by-step explanation:

slope-intercept form: y = mx + b

Given: Slope: -4

Point: (-2, 2)

To write an equation in slope-intercept form, we need to know the slope(m) and the y-intercept(b). Since we were given the value of the slope, all we have to do now is find b. To do this, input the given values of m and the point into the equation and solve for b:

y = mx + b

2 = -4(-2) + b

2 = 8 + b

-6 = b

The y-intercept is -6.

Now that we know the slope and the y-intercept, we can write the equation:

y = -4x - 6

Answer:

y=-7x-2

input -4 (x)

y=-7(-4)-2

y=28-2

y=26

Answer:

Step-by-step explanation:

The formula you need for this is

[tex]A(t)=P(1+\frac{r}{n})^{nt}[/tex]

where A(t) is the final amount after the compounding is done, P is the initial investment, r is the interest rate in decimal form, n is the number of times per year that the money is compounded, and t is the time in years. Filling in accordingly:

[tex]1708=1170(1+\frac{r}{4})^{(4)(6)}[/tex]

First things first. Simplify by division and then multiply the n by the t to get the exponent:

Divide 1708 by 1170 to get the equation:

[tex]1.45982906=(1+\frac{r}{4})^{24}[/tex]

Undo the 24th power by taking the 24th root of both sides to get:

[tex]1.015888202=1+\frac{r}{4}[/tex] Now subtract 1 from both sides to get

[tex].0158882024=\frac{r}{4}[/tex] Multiply both sides by 4 to finish it off and get that

r = .0635528 but since we want the percentage, we move the decimal 2 places to the right and round to r = 6.4% which is choice A.

  (-98, 18)

Step-by-step explanation:

We recognize the equation as being in the "point-slope" form.

  y -k = m(x -h) . . . . . . . a line with slope m through point (h, k)

__

Comparing this form to the given equation, we identify the parameters as ...

  k = 18, m = 71.3, h = -98

Step-by-step explanation:

We are told Jason has 34 strawberry scones and 85 raspberry scones and that he wanted to make as many identical bags of scones as possible and that each bag should have an equal number of strawberry scones and an equal number of raspberry scones.

To calculate greatest number of bags Jason can fill, we find the factor of 34 and 85 and choose the highest that's common to both.

Factor of 34 = 1, 2 , 17, and 34

Factor of 85 = 1, 5, 17, and 85.

Highest common factor = 17

The answer is 17
