O persoană avea 1200 lei și a cheltuit 15% din ei pentru o camașă si 40% din ei pe o pereche de pantofi.Ce sumă i-a rămas?
Answer:
540 lei
Step-by-step explanation:
Pasul 1
Suma cheltuită pe cămașă se calculează astfel:
1200 lei × 15%
= 1200 lei × 15/100
= 180
Pasul 2
Suma cheltuită pentru o pereche de pantofi se calculează astfel:
1200 lei × 40%
= 1200 lei × 40/100
= 480 lei
Pasul 3
Suma rămasă este calculată ca:
Suma totală - (Suma cheltuită pe cămașă + Suma cheltuită pe încălțăminte)
1200 lei - (180 + 480) lei
1200 lei - 660 lei
= 540 lei

Answer:
NO. Emma is not correct.
Step-by-step explanation:
✔️Initial value for Function A:
The initial value is the y-intercept of the graph. The y-intercept is the point at which the line intercepts the y-axis. From the graph given, the line intercepts the y-axis, at y = 2, when x = 0.
Initial value for Function A is therefore = 2
✔️Initial Value of Function B:
To find the initial value/y-intercept for Function B, do the following:
Using two pairs of values form the table, (2, 2) and (4, 3), find the slope:
Slope (m) = ∆y/∆x = (3 - 2) / (4 - 2) = 1/2
Slope (m) = ½
Next, substitute (x, y) = (2, 2) and m = ½ into y = mx + b, to find the intial value/y-intercept (b).
Thus:
2 = ½(2) + b
2 = 1 + b
2 - 1 = b
1 = b
b = 1
The initial value for Function B = 1
✅The initial value for Function A (2) is not the same as the initial value for Function B (1). Therefore, Emma is NOT CORRECT.

Answer:
a) 258 kmb) 267°c) 87°Step-by-step explanation:
Refer to attached diagram (not to scale).Given details are reflected.First find the measure of angle Q
m∠Q = 36° + (180° - 125°) = 91°a) Use law of cosines to find x:
x = √(160² + 200² - 2160*200*cos 91°) = 258 km (rounded)Use the law of sines to find the missing angles:
258 / sin 91 = 160 / sin R = 200 / sin Pm∠R = arcsin (160 sin 91° / 258) = 38°m∠P = 180° - (91° + 38°) = 51°b) Bearing P from R:
360° - (55° + 38°) = 267°c) Bearing R from P:
36° + 51° = 87°Answer:
a) Use law of consines to find x:
x=(160 2+200 2-2160×200× cos 91 grades) =258 km.
b) Bearning P from R:
360 grades - ( 55 degrees + 38 degrees)

GEOMETRY
Answer:
[tex] m\widehat {WV} = 50\degree[/tex]
Step-by-step explanation:
Let O be the center of the circle.
[tex] m\angle VOU =m\angle TOU... (given) [/tex]
[tex] \therefore m\angle VOU =(5x + 10)\degree[/tex]
[tex] [\because m\angle TOU = (5x +10)\degree] [/tex]
[tex] m\widehat {TUV} = (5x +10)\degree + (5x +10)\degree [/tex]
[tex] m\widehat {TUV} = (10x +20)\degree [/tex]
[tex] m\widehat {SW} =m\widehat {TUV} [/tex]
[tex] (12x-2)\degree = (10x +20)\degree [/tex]
[tex] 12x-2 = 10x +20 [/tex]
[tex] 12x-10x = 2 +20 [/tex]
[tex] 2x = 22 [/tex]
[tex] x = \frac{22}{2}[/tex]
[tex] x = 11[/tex]
[tex] m\widehat {WV} = 180\degree - m\widehat {TUV}[/tex]
[tex] m\widehat {WV} = 180\degree - (10x +20)\degree[/tex]
[tex] m\widehat {WV} = 180\degree - (10\times 11+20)\degree[/tex]
[tex] m\widehat {WV} = 180\degree - 130\degree[/tex]
[tex] m\widehat {WV} = 50\degree[/tex]

Carmen is filling a tank with water at a rate of 4 gallons per minute. The tank already had 170 gallons of water in it. Suppose the tank holds a total of 350 gallons of water. How much longer will it take her to fill the tank?
(a) Write an equation to help answer the question above.
Choose the correct form below and fill in the blanks using only 4, 170, and 350.
(The variable x is used to represent the number of minutes.)
o_x+_=_
or
o_-_=_
(b) Write an expression to help answer the question above.
Choose the correct form below and fill in the blanks using only 4, 170, and 350
o_+_
_
or
o_-_
_
(c) How much longer will it take Carmen to fill the tank?
_ minutes
Answer: In explanation
Step-by-step explanation: 350-170=4x
Solve 180=4x
45=x 45 minutes longer
4x+170=350 because you would want to subtract 170 from each side not add 170 to each side when simplifying
4x+170 because that is how much gas the tank can hold. You need to have 4x in the equation and 350 and 4x wouldn't make sense so use 4x and 170.
45 minutes as stated above.

If there is 45 ml of milkshake left .She used 1 part strawberry cream to 4 parts milk .How many ml of milk is left?
Given:
Remaining milkshake = 45 ml
She used 1 part strawberry cream to 4 parts milk.
To find:
The remaining amount of milk.
Solution:
It is given that, she used 1 part strawberry cream to 4 parts milk. It means the ratio of strawberry cream and milkshake is 1:4.
Let the remaining amount strawberry cream be x and the remaining amount of milk is 4x. Then,
[tex]x+4x=45[/tex]
[tex]5x=45[/tex]
[tex]x=\dfrac{45}{5}[/tex]
[tex]x=9[/tex]
Now, the remaining amount of milk is:
[tex]4x=4(9)[/tex]
[tex]4x=36[/tex]
Therefore, the remaining amount of milk is 36 ml.

In your own words, explain the steps you would need to take to find a slope from data in a table.
Answer:
Pick two points on the line and determine their coordinates. Determine the difference in y-coordinates of these two points (rise). Determine the difference in x-coordinates for these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).
Step-by-step explanation:
Answer:
To Find the slope of a data table, you first need to plot two points on the line. It is easiest if the points are on a coordinate with whole numbers (i.e. (3,6 and (4,8)). Once you have plotted two pints, you then need to take the value of the point with the largest x value, and subtract the other points from it (i.e. (4,8)-(3,6)=(1,2). Then, take the new y value, and divide it by the new y-value (i.e. (2/1), and you have your slope.
Step-by-step explanation:
plot points (3,6), (4,8)
subtract points (4,8)-(3,6)=(1,2)
divide new points 2/1
m=2/1, or 2

8300 dollars is placed in an account with an annual interest rate of 6.5%. How much will be an account after 14 years, to the nearest cent?
Answer:
$ 20,043.46
Step-by-step explanation:
Answer:
A = $ 20,043.46
A = P + I where
P (principal) = $ 8,300.00
I (interest) = $ 11,743.46
Calculation Steps:
First, convert R percent to r a decimal
r = R/100
r = 6.5%/100
r = 0.065 per year,
Then, solve our equation for A
A = P(1 + r/n)nt
A = 8,300.00(1 + 0.065/1)(1)(14)
A = $ 20,043.46
Summary:
The total amount accrued, principal plus interest,
from compound interest on an original principal of
$ 8,300.00 at a rate of 6.5% per year
compounded 1 times per year
over 14 years is $ 20,043.46.
