Answer:
32 yards
Step-by-step explanation:
Subtract 15.52 by 20 to find out how much she spent.
She spent $4.48.
Divide 0.14 to find out how many yards of ribbon $4.48 can buy.
She bought 32 yards.
Division is one of the four fundamental arithmetic operations. The number of yards of ribbon is 33.93 yards.
What is Division?The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given that Isabel prepaid a debit card with $20 on it. Also, after that purchase, there was $15.52 left on the card. Therefore, the cost of the total ribbon can be written as,
Cost of total Ribbon = Total Balance in debit card - Balance after purchase
= $20 - $15.25
= $4.75
It is further mentioned that the price of the ribbon was 14 cents per yard. Therefore, we can write,
Yards of ribbon = Cost of total Ribbon / Cost of a yard of ribbon
= $4.75 / $0.14 per yards
= 33.93 yards
Hence, the number of yards of ribbon is 33.93 yards.

Answer:
1) 0.25
2) -2.342
Step-by-step explanation:
Given the coordinates below, determine if ΔFGH and ΔJKL are congruent. If they are, give the reason, if they aren't choose "not congruent".
F(-5, 10), G(-2, 2), H(-9, -7), J(0, -5), K(9, 2), L(-8, -2)
*enter your lengths to the NEAREST TENTH
Answers:
FG = 8.5 GH = 11.4 FH = 17.5 JK = 11.4 KL = 17.5 JL = 8.5The triangles are congruent by SSS=======================================================
Explanation:
Use the distance formula to compute the length of each segment. For instance, the distance from point F to point G is the length of segment FG.
I'll show the steps on finding the length of FG
[tex]F = (x_1,y_1) = (-5,10)\\\\G = (x_2,y_2) = (-2,2)[/tex]
[tex]d = \text{distance from F to G}\\\\d = \text{length of segment FG}\\\\d = \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\\\\d = \sqrt{(-5-(-2))^2+(10-2)^2}\\\\d = \sqrt{(-5+2)^2+(10-2)^2}\\\\d = \sqrt{(-3)^2+(8)^2}\\\\d = \sqrt{9+64}\\\\d = \sqrt{73}\\\\d \approx 8.544\\\\d \approx 8.5\\\\[/tex]
The length of segment FG is approximately 8.5 units. The other side lengths are handled in the same way. As an alternative, you can use the pythagorean theorem.
---------------------
Once you determine all six lengths, note we have the following three pairs of corresponding congruent sides:
FG = JL = 8.5GH = JK = 11.4FH = KL = 17.5Because we have three pairs of equal sides, this means we can use the SSS (side side side) congruence theorem to prove the triangles are congruent. In other words, we have two identical triangles. One triangle is a rotated and reflected copy of the other.

if buying a pound of something is 6$ how much is 2.6 pounds
Answer: 15.6
Step-by-step explanation: 2.6 x 6 = 15.6
Answer:
$15.60
Step-by-step explanation:
If buying a pound of something is $6 then 2 pounds is $12.
0.6 pounds would be $3.60
1 = $6
0.9 = $5.40
0.8 = $4.80
0.7 = $4.20
0.6 = $3.60
0.5 = $3.00
0.4 = $2.40
0.3 = $1.80
0.2 = $1.20
0.1 = $0.60

similar
Answer:
They are similar using the angle-angle property.
Step-by-step explanation:
Since you know that 2 of the angles are congruent, you can use this to prove triangle similarity.
By AA similarity, triangle PQR similar to triangle STU.
What are similar triangles?Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.
The two given triangles PQR and STU.
Here, ∠P=63° and ∠R=45°
In triangle STU, ∠S=63° and ∠U=45°
Now, ∠P=∠S=63° and ∠R=∠U=45°
Since angles of triangle are congruent
By AA similarity, ΔPQR similar to ΔSTU
Therefore, triangles are similar.

Step-by-step explanation:
To do 20% of 25, you must first move the % until all numbers are on the right side of the decimal.
Observe: 20% ---> 0.20 aka 0.2
Now, you must take 0.2 and multiply it by 25 to get 20% of 25.

equation: (y-0)/(x-6) = -3
y = -3x +18
Graph y + 14 = -7x help me pls
Answer:
see attached graph
Step-by-step explanation:
There are a couple of ways you can look at this.
Point-Slope Form
The point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . . . . line with slope m through point (h, k)
Comparing this to the given equation, we see that ...
k = -14, m = -7, h = 0
That is, the equation describes a line with slope -7 through point (0, -14).
The slope is the ratio of rise to run. Usually, "run" is considered to be positive in the +x direction (to the right). Here, you run out of room on most graphs if you look for a point that is 7 units down and 1 unit right of the y-intercept at (0, -14). (That point is (1, -21).) So, it is more convenient to start at the y-intercept (0, -14) and go 1 unit left and 7 units up to find another point on the line. That point is (-1, -7). With two points plotted, you can draw the graph.
__
Slope-Intercept form
We discovered above that the y-intercept is -14. You can get there also by putting the equation in slope-intercept form:
y = mx +b . . . . . . line with slope m and y-intercept (0, b)
Adding -14 to both sides of the given equation gives you this form.
y = -7x -14
The method of plotting is substantially identical to that described above.
__
Standard form
The standard form of the equation is ...
ax +by = c
where a > 0, and a, b, c are mutually prime integers.
Adding 7x-14 to both sides of the equation puts it into standard form:
7x +y = -14
The x- and y-intercepts are found by setting the other variable to zero and solving for the one that is left. Here, that means the x-intercept is ...
c/a = -14/7 = -2
and the y-intercept is ...
c/b = -14/1 = -14
These x- and y-intercepts are easily plotted on the x- and y-axes. The graph will be the line drawn through them. The attached graph shows the line and the intercepts.

Nathan usually drinks 33 ounces of water per day. He read that he should drink 59 ounces of water per day. If he starts drinking 59 ounces, what is the percent increase? Round to the nearest percent.
Step-by-step explanation:
33oz = 100%
1% = 100%/100 = 33/100 = 0.33oz
59 - 33 = 26oz increase
how many % are these 26oz compared to the original 33oz ?
we need to see how often 1% fits into 26oz.
26/0.33 = 78.78787878...%
rounded this means a 79% increase of drinking water.
