Blanca jogged 8 days last month she jogged 1.25 miles on each day and burned 140 calories per mile while jogging how many calories did Blanca burn by jogging last month
Answer:
140p calories
Step-by-step explanation:
Bianca is said to have jogged km 8 days, while also completing 1.25 miles every day. First, we calculate the total number of miles Bianca jogged in total, and that is
8 * 1.25 = 10 miles
Therefore, Bianca jogged a total of 10 miles the previous month.
Again, it is said that Bianca burned 140 calories per each mile she jogged and were asked to find the total calories that was burnt.
If Bianca burns 140 calories per mile, then she must have burnt 140 * 10 calories in 10 miles.
Therefore, we conclude that Bianca burnt 1400 calories.

A florist sells a bouquet of roses
for $16 each and a bouquet of carnations
for $10 each. The shop sells 28 bouquets
today and makes $400. How many bouquets of
roses did the shop sell today and how many
bouquets of carnations were sold today?
Answer:
Bouquets of roses = 20
Bouquets of carnations = 08
Step-by-step explanation:
Let,
x be the bouquets of roses sold
y be the bouquets of carnations sold
According to given statement;
x + y = 28 Eqn 1
16x + 10y = 400 Eqn 2
Multiplying Eqn 1 by 16
16(x+y=28)
16x + 16y = 448 Eqn 3
Subtracting Eqn 2 from Eqn 3
(16x+16y)-(16x+10y) = 448 - 400
16x + 16y - 16x - 10y = 48
6y = 48
Dividing both sides by 6
[tex]\frac{6y}{6}=\frac{48}{6}\\y=8[/tex]
Putting y=8 in Eqn 1
x + 8 = 28
x = 28 - 8
x= 20
Hence,
Bouquets of roses = 20
Bouquets of carnations = 08

Complete the steps to solve the inequality:
0.2(x + 20) – 3 > –7 – 6.2x
Answer:
0.2x + 4 - 3 > -7 - 6.2x
0.2x + 6.2x > -7 -1
6.4x > -8
x < 1.25
Answer:
x > -1.25
Step-by-step explanation:
0.2x + 4 – 3 > –7 – 6.2x
0.2x + 1 > –7 – 6.2x
6.4x + 1 > –7
6.4x > –8
x > -1.25

13. If l is parallel to m, find the values of x and y.
Answer: 14. x = 16; y = 23
15. x = 9; y = 13
Step-by-step explanation:
14. (4x + 4) = (7x - 44) (alternate exterior angles are congruent)
4x + 4 = 7x - 44
Collect like terms
4x - 7x = -4 - 44
-3x = -48
Divide both sides by -3
x = -48/-3
x = 16
39° + (8y - 43)° = 180° (consecutive exterior angles are supplementary)
39 + 8y - 43 = 180
Add like terms
-4 + 8y = 180
Add 4 to both sides
8y = 180 + 4
8y = 184
Divide both sides by 8
y = 184/8
y = 23
15. (15x - 26)° = (12x + 1)° (alternate exterior angles are congruent)
15x - 26 = 12x + 1
Collect like terms
15x - 12x = 26 + 1
3x = 27
Divide both sides by 3
x = 27/3
x = 9
28° + (12x + 1)° + (4y - 9)° = 180° (sum of interior angles of ∆)
Plug in the value of x
28 + 12(9) + 1 + 4y - 9 = 180
28 + 108 + 1 + 4y - 9 = 180
Add like terms
128 + 4y = 180
Subtract 128 from each side of the equation
4y = 180 - 128
4y = 52
Divide both sides by 4
y = 52/4
y = 13

use the trigonometry mnemonic (new monic) to help remember how sin cos and tan fit on the triangle
since you know the angle and you want to know the side opposite of that angle... and you know the side adjacent ( next to) the angle... use Tan
use the mnemonic to help
Tan(Ф)= Opp/ Adj ( we know two of these things and we want the 3rd :P )
Adj * Tan(25) = Opp
250 * Tan(25) = Opp
116.5769.... = Opp
x = 116.6 ft. approx. in the picture

27= -3y + x
2 y=10 - 4x
Answer:
x=6 y=-7
Step-by-step explanation:
rearrange the equation
3y=x-27 eq 1
2y=-4x+10 eq 2
Multiply eq 1 by 2, and eq 2 by 3
6y=2x-54
6y=-12x+30 subtract the two eq's
0=14x-84
84=14x
x=84÷14
x=6
solving for y sub. x either eq 1 or 2
3y=x-27
3y=6-27
3y=-21
y=-21÷3
y=-7
The area A of a rectangle is represented by the formula A = lw, where l is the length and w is the width. The length of the rectangle is 5. Write an equation that makes it easy to find the width of the rectangle if we know the area and the length. *

John bought a shirt on sale for 25% off the original price and another 25 % off the discounted price. If the final price was $16, what was the price before the first discount?
Answer: original price = p
price after first 24% discount = .75p
he second 25% discount reduces the already reduced price to .75*.75p = .5625p
So, if .5625p = 16,
p = 16/.5625 = $28.44
check:
25% off $28.44 = $21.33
25% off $21.33 = $16.00
