If the speed limit is 80 kilometers per hour, and Elena’s mom was driving 75 miles per hour, was she speeding? By how much?

Answer:

227.63 meters^2

Step-by-step explanation:

The formula to find an area of a parallelogram is a = bh (base multiplied by height). According to the figure, the base is 22.1 meters and the height is 10.3 meters.

a = bh
a = 22.1(10.3)
a = 227.63 meters^2

Step-by-step explanation:

just put the number they give you for x and solve and the answer you get is the answer for y

Answer:

Step-by-step explanation:

Given the slope-intercept form:[tex]y=\frac{1}{3}x-2[/tex]

Slope-intercept form: [tex]y=mx+b[/tex]

We substitute our x-values (-9, -3, 0, 6, and 9) for x in [tex]y=\frac{1}{3}x-2[/tex] to find the y-values.

For -9:

[tex]y=\frac{1}{3}x-2 < ==substitute\ -9\ for\ x\\\\y=\frac{1}{3}(-9)-2\\\\y=\frac{-9}{3}-2 < ==divide\ (don't\ forget\ the\ signs)\\\\y=-3-2 < ==add\ or\ subtract\\\\y=-5 < =value\ of\ y\\\\(-9,-5)[/tex]

For -3:

[tex]y=\frac{1}{3}x-2 < ==substitute\ -3\ for\ x\\\\y=\frac{1}{3}(-3)-2\\\\y=\frac{-3}{3}-2 < ==divide\ (don't\ forget\ the\ signs)\\\\y=-1-2 < ==add\ or\ subtract\\\\y=-3 < =value\ of\ y\\\\(-3,-3)[/tex]

For 0:

[tex]y=\frac{1}{3}x-2 < ==substitute\ 0\ for\ x\\\\y=\frac{1}{3}(0)-2 < ==any\ number\ multiplied\ by\ 0\ equals\ zero\\\\y=\frac{0}{3}-2 < ==divide\ (don't\ forget\ the\ signs)-zero\ divided\ by\ any\ \#\ equals\ 0\\\\y=0-2 < ==add\ or\ subtract\\\\y=-2 < =value\ of\ y\\\\(0,-2)[/tex]

For 6:

[tex]y=\frac{1}{3}x-2 < ==substitute\ 6\ for\ x\\\\y=\frac{1}{3}(6)-2\\\\y=\frac{6}{3}-2 < ==divide\ (don't\ forget\ the\ signs)\\\\y=2-2 < ==add\ or\ subtract\\\\y=0 < =value\ of\ y\\\\(6,0)[/tex]

For 9:

[tex]y=\frac{1}{3}x-2 < ==substitute\ 9\ for\ x\\\\y=\frac{1}{3}(9)-2\\\\y=\frac{9}{3}-2 < ==divide\ (don't\ forget\ the\ signs)\\\\y=3-2 < ==add\ or\ subtract\\\\y=1 < =value\ of\ y\\\\(9,1)[/tex]

Answer:

Step-by-step explanation: The probability of rolling an even number is three out of six, or three-sixths. This fraction can be simplified as the numerator and denominator are both divisible by three.

Answer:

Only the first option. 10-2

Step-by-step explanation:

2.75 x 2 + 3 x 1.5 - 2

= 8

10 - 2 = 8

2.75 x 2 + 2.25 = 7.75

8.5 x 1.5 - 2 = 10.75

5.5 + 3 x(-0.5) = 4

Therefore, Only the first option is correct.

Answer:

$1,169.30

Step-by-step explanation:

The answer is $1,169.30 since 621.60-600=21.60, meaning that in the past 4 years, Chelsea has gained $21.60. Then you would do 21.60/4 to find how much per year, which would get you $5.40. Then you need to find the interest rate by doing 5.40/600 since she started out with 600. 5.40/600=0.009. Then you would turn it into percentage by multiplying it by 100, to get 0.9%. Now, since she's deposited $1,100 instead, you would do 0.9*1,100, and then you would get 990, then you would have to divide it by 100 and get $9.90. That means she gains $9.90 per year. Since she'll have it for 7 years, you need to do 9.90*7=63.90. Then you would add it to 1,100 to get $1,169.30

The area decreases by 1155.52 square meters

What we must do is calculate the area before and after making the diameter cut.

The area of a circle is equal to:

a = pi * r ^ 2

now the diameter is equal to:

d = 2 * r

therefore r,

r = d / 2

before the cut would be

r = 96/2

r = 48

replacing in the area formula

a1 = 3.14 * 48 ^ 2

a1 = 7234.56 square meters.

after cutting the diameter decreases by 8, that is, 96 - 8 = 88, calculating the radius would be:

r = 88/2

r = 44

now calculating the new area would be:

a2 = 3.14 * 44 ^ 2

a2 = 6079.04 square meters.

now we calculate the difference

a1 - a2 = 7234.56 - 6079.04

= 1155.52 square meters

means that the area decreases by 1155.52 square meters

Answer:

x > 7

Step-by-step explanation:

-8x+40>-16

You do 40 minus 40, and that cancells it out, then you  do -16 minus 40, wich gives you -56, then, you do -1 divided by -8, wich, again, cancels it out, and finally, do -56 divided by -8 wich gives you 7, so, x=7.

Step-by-step explanation:

Answer:

Sarah=S

SungSo=U

Semir=E

1.

A. (2+S)+(3s)+S

B. SungSo sold 26 meals and Semir sold 72 meals.

C. In total the meals sold are 122 meals. The commutative property plays a role in this problem since it doesn't matter which order you add them in. The associative property also shows that it doesn't matter in which way you group the addends.

2.

A. (2n-5)*18

B. (450/18-5)/2=10

C. 25 miles

D. (25*18-72)/18=21

3. In total, SungSo, Sarah, and Semir have raised $1,080 and sold 122 meals in total. SungSo sold 26 meals, Semir sold 72 meals, and Sarah sold 24 meals. SungSo raised $378, plus the $72 donation which brings the money to $450, Semir raised $180, and Sarah raised $450.

Step-by-step explanation:

1.

A. The equation is (2+S)+(3s)+S since Sarah=S, SungSo sold 2 more meals than Sarah, and Semir sold 3 times as many meals as Sarah.

B. SungSo sold 26 meals and Semir sold 72 meals because if you plug it in with the equations, (2+24)=26 meals for SungSo and (3*24)=72 meals for Semir.

C. In total the meals sold are 122 meals since (2+24)+(3*24)+24=122. The commutative property plays a role in this problem since it doesn't matter which order you add them in. The associative property also shows that it doesn't matter in which way you group the addends.

2.

A. The answer is (2n-5)*18 because Sarah walked 5 miles less than twice the number of miles that Semir walked, n.

B. The answer is (450/18-5)/2=10 because then you would need to use the same equation as you used in part A, but use it inversely since now you have how much Sarah collected instead of how many miles Semir walked.

C. Sarah walked 25 miles since she earns $18 per mile and she earned $450, so 450/18=25.

D. The answer is (450-72)/18=21 because he collected the same amount of money as Sarah which is 450. He also recieve a donation of $72 from his Grandmother, so you would subtract that and then divide it by 18 to find how many miles he walked.

3. In total, SungSo, Sarah, and Semir have raised $1,080 and sold 122 meals in total. SungSo sold 26 meals, Semir sold 72 meals, and Sarah sold 24 meals. SungSo raised $378, plus the $72 donation which brings the money to $450, Semir raised $180, and Sarah raised $450.
