Answer:

145, 29, 2.9

Step-by-step explanation:

To convert 14.5 into tenths, first split the number apart.

0.5 is another way of saying one half or 1/2 which is also 5/10.

14 is the same as saying 14/1. If you want tenths, add a zero to the bottom and top which gives you 140/10

So put back together, you have 145/10 or 145 tenths.

The second question is to divided 145/10 by 5.

When you divide a fraction by a whole number you first have to change the whole number into a fraction.

145 5

----- divided by -----

10 1

When you divided fractions, you flip the fraction that you are dividing by which was the 5. Then you multiply the new fractions. Now you would have:

145 1 145

----- X ----- = -------

10 5 50

Convert this into tenths by dividing the top and bottom by 5.

145 145/5 29

----- = --------- = -------

50 50/5 10

The last question is to convert the above fraction back into a non-fraction.

Divide the top and bottom by 10.

The question has to do with finding the proven with the given and I’m not sure what to do

Using the two parallel line theorems we proved that ∠8 ≅ ∠4.

In the given question,

Given: f || g

Prove: ∠8 ≅ ∠4

We using given diagram in proving that ∠8 ≅ ∠4

Since f || g, by the Corresponding Angles Postulate which states that "When a transversal divides two parallel lines, the resulting angles are congruent." So

∠8≅∠6

Then by the Vertical Angles Theorem which states that "When two straight lines collide, two sets of linear pairs with identical angles are created."

∠6≅∠4

Then, by the Transitive Property of Congruence which states that "All shapes are congruent to one another if two shapes are congruent to the third shape."

∠8 ≅ ∠4

Hence, we proved that ∠8 ≅ ∠4.

Choose the correct conic section to fit the equation.

yanalaym [24]

Answer:

Option A) Circle.

Step-by-step explanation:

We are given the equation:

$(x - 3)^2 + (y - 12)^2 = 25$

A general equation of the circle is of the form:

$(x-h)^2 + (y-k)^2 = r^2$

where (h,k) is the center of the circle and r is the radius of circle.

Comparing the two equations, we get,

$(h,k) = (3,12)\\r = \sqrt{25} = 5$

Thus, the given equation is equation of a circle centered at (3,12) and of radius 5 units.

Pedro is doing math exercises from a software program he recently purchased. In the program, you have to get at least 70% of the

Nookie1986 [14]

The inequality would be
0.75q ≥ 0.70(q+1)

q is defined as the number of questions he answers after the first one. We are told he gets 75% of those correct; 75%=75/100=0.75. This gives us 0.75q.

Since he gains proficiency on the exercises, the total number he gets correct has to be at least 70%. This means the inequality would have the symbol greater than or equal to, as it cannot be less and have him gain proficiency.

He has already answered 1 question and answers q more; this gives us a total of q+1. Since he gains proficiency, the cutoff was 70%; 70%=70/100=0.70. This gives us the expression 0.70(q+1).

Our total inequality would then be 0.75q ≥ 0.70(q+1)
