Answer:

Not congruent

Step-by-step explanation:

They are not congruent because in order of congruency will have an angle(the ones marked with red) -

side( the side that the two triangles shares so are congruent by reflexive property ) -

side ( the one marked with the red line)

and this is not a theorem of congruency.

We are asked to find the distance Louise cycled.

Speed Louise cycled = 12 mph

Time = 11: 30 am to 12 : 15 pm

= 45 minutes

Convert 45 minutes to hour

60 minutes = 1 hour

45 minutes = 3/4 hour

Speed = Total distance ÷ Total time taken

Distance = Speed × Time

= 12 mph × 3/4 hour

= 36 / 4

= 9 miles

Therefore, the total distance Louise cycled is 9 miles

Step-by-step explanation:

Edge 2021

Answer:

a) $160

b) $116.50

Step-by-step explanation:

a) Let the original price of the yellow bicycle be $x.

Since both has the same original price,

original price of yellow bicycle= 100% x

original price of green bicycle= 100% x

Discounted price of yellow bicycle

= (100% -25%) x

= 75% x

Discounted price of green bicycle

= (100% -30%) x

= 70% x

Difference in cost

= 75%x -70%x

= 5% x -----(1)

From 2nd paragraph:

Discounted price of yellow bicycle

= Kyreen's money +3.50

Discounted price of green bicycle

= Kyreen's money -4.50

Difference in cost

= (Kyreen's money +3.50) -(Kyreen's money -4.50)

= Kyreen's money +3.50 -Kyreen's money +4.50

= 3.50 +4.50

= 8.00 -----(2)

Equating (1) and (2) together:

5% x= 8.00

[tex] \frac{5}{100} x = 8[/tex]

[tex]x = 8 \div \frac{5}{100} [/tex]

[tex]x = 8 \times \frac{100}{5} [/tex]

x= 8 ×20

x= 160

Thus, the original price of the yellow bicycle is $160.

_______

b) Amount Kyreen has at first

= discounted price of yellow bicycle -$3.50

= 75%($160) -$3.50

= $120 -$3.50

= $116.50

The animals in order of least to greatest speed are Brown Elk, Hare, Blue Wildebeest, and Cheetah, with speeds approximately 45, 48, 50, and 70 miles per hour respectively.

Ordering the animals from least to greatest speed based on their provided speeds are :

(1) Brown Hare: 8 miles in 1/6 hours, which is approximately 48 miles per hour.

(2) Cheetah: 7 miles in 1/10 hours, which is 70 miles per hour.

(3) Blue Wildebeest: 100/3 miles in 2/3 hours, which is 50 miles per hour.

(4) Elk: 18 miles in 2/5 hours, which is 45 miles per hour.

Therefore, the animals in order from least to greatest speed are Brown Elk, Hare, Blue Wildebeest, and Cheetah.

Answer:

thank You for your points this is the answer

Slope is calculated as the change in y over the change in x so you would need to do 5- (-5) which turns the negative sign to a positive making it 5+5=10 and the same thing with the 2s 2-(-2)=4 so the answer would be 10/4 or 5/2. Billy did the reciprocal.

Answer:

correct answer is 5/2

Step-by-step explanation:

the mistake was the student took the difference of the x-values and it in the numerator and the difference of the y-values should be the denominator

5-(-5) / 2-(-2) = 10/4 or 5/2
