carney needs $60 to buy her mother a gift. She has saved 25% of that amount so far. Bow much has she saved so far
Answer:
$15.00
Step-by-step explanation:
25% of anything means a quarter of that thing. (ie.1/4 of $60 which is $15).
OR
(25/100)*$60
0.25*60=$15
if y varies directly with x and y is 12 when x is 9 what is x when y is 4
Answer:
X is 3 when Y is 4.
So, the required value [tex]x[/tex] is 3.
Proportional:Properly related in size, degree, or other measurable characteristics; corresponding: Punishment ought to be proportional to the crime. 3. Mathematics Having the same or a constant ratio.
The first part is y varies directly with x then,
[tex]y \propto x\\y=kx[/tex]... (1) where k is proportional constant
Now, substituting [tex]y=12, x=9[/tex] in equation (1) we get,

ABC So the measure of in24_49 Because vertical angles
Answer:
Step-by-step explanation:
The correct question is shown in the image attached below.
Recall that: the line m is parallel to line n. In addition to that, [tex]m \angle 1 = 50^0[/tex] and [tex]m \angle 2 = 48^0[/tex], and [tex]\angle ABC[/tex] is bisected by line s.
At this moment, by the angle addition postulate, angle DEF i.e.
∠DEF [tex]= m \angle 1 + m \angle 2[/tex]
∠DEF = 50° + 48°
∠DEF = 98°
Similarly, using the rule of the alternate exterior angle ∠DEF = ∠ABC (∵ alternate exterior angles exhibit congruency).
Furthermore, By the definition of a bisector, angles 4 and 5 are congruent due to the fact that the line of a bisector splits the angle into two equal parts.
m∠4 = m∠5
∴
98/2 = 49°
Finally;
from the diagram, angle 3 and 4 are vertical angles
Thus, m∠3 = 49 by substitution property of equality ( because vertical angles are congruent angles).

You are testing two scales for accuracy by weighing two different objects.
Use the drop-down menus to complete the statements about the scales' accuracy.
Answer:
This is because the object on the 1st scale weighs (more) than the object on second scale, each pound of error results in a (lesser) percent error. The first scale was (10) pounds off the second scale,was (3) pounds off, so 1st scale was (10)% off 2nd scale was (12)% off.
Answer:
Because the object on Scale 1 weighs more than the object on Scale 2, each pound of error results in a lesser percent error. Scale 1 was 10 pounds off and Scale 2 was 3 pounds off, so Scale 1 was 10% off and Scale 2 was 12% off.

Nat is thinking of a four-digit counting number. The thousands digit and the hundreds digit are the same. The sum of all 4 digits is 28. The four-digit number is an odd multiple of 5. Exactly two digits are even. What is Nat’s number?
We want to use the given information to find a 4-digit number.
We will get the number: 8,875
----------------------------
A general 4-digit number can be written as:
a*1,000 + b*100 + c*10 + d
Where a, b, c, and d are whole numbers between [0, 9].
We also know that:
"The thousands digit (a) and the hundreds digit (b) are the same"
a = b.
"The sum of all 4 digits is 28"
a + b + c + d = 28
"The 4-digit number is an odd multiple of 5"
All the multiples of 5 end with a 0 or a 5, this is an odd one, so it must end with a 5, then we know that:
d = 5
"Two of the digits are even".
Ok, now let's write the equations that we found
a = b
a + b + c + d = 28
d = 5
Because of the last statement, only two digits are even, and we have that a is equal to b, the two even numbers must be these two, then we know that:
a is even.
And from the first equation, we can rewrite the second one as:
a + a + c + d = 28
Using the third equation and replacing it here, we have:
a + a + c + 5 = 28
2*a + c = 23
Now we can try to input different values of a in the equation, and see what value of c we get:
if a = 2, then:
2*2 + c = 23
4 + c = 23
c = 23 - 4 = 19
But c can be, at max, 9, then we can discard this.
Now let's try with a larger value for a, this time a = 8.
2*8 + c = 23
16 + c = 23
c = 23 - 16 = 7
c = 7
This is correct, then we can conclude that:
a = 8b = 8c = 7d = 5Then the 4-digit number is:
8,875

Alia made a scale drawing of a square park, which has a side length of 30 feet. She used the scale 3 centimeter = 5 feet. What will be the area of the scale drawing?
Answer:
324cm²Step-by-step explanation:
Given the scale conversion;
3 centimeter = 5 feet
x = 30 feet
Cross multiply
5x = 3 * 30
5x = 90
x = 90/5
x = 18cm
Hence the side length in cm is 18cm
Area of the square = L²
Area of the square = 18²
Area of the square = 324cm²
Hence the area of the scale drawing is 324cm²

Miss Rojas has a container of Jolly Ranchers on her desk. The ratio of Red Jolly Ranchers to Green Jolly Ranchers is 3 to 7. If there are 42 green jolly ranchers in the container, what is the total amount of Jolly Ranchers in the container?
Answer:
The total amount of Jolly Ranchers in the container is 60 Jolly Ranchers
Step-by-step explanation:
We have a ratio of
Red Jolly Ranchers : Green Jolly Ranchers
3:7
Sum of the proportion = 3 + 7 = 10
Hence:
Let the total number of jolly ranchers = x
7/10 of x = 42 Green Jolly Ranchers
Hence:
7/10 × x = 42
7x /10 = 42
Cross Multiply
7x = 420
x = 420/7
x = 60 Jolly Ranchers
The total amount of Jolly Ranchers in the container is 60 Jolly Ranchers

it's weird my brother And I am fighting for this my brother says it's p but I think it's P-Q
Answer: U - (P - P∩Q)
Where U represents the universal set.
Step-by-step explanation:
In the image, we can see that the shaded part is all the region minus the part of P that does not share elements with Q.
This part of P can be written as:
P - P∩Q
there we write:
"The elements of P, minus the elements that P share in common with Q"
Then to write the shaded area, we need to write the universal set, U, minus the thing we wrote above, this is:
U - (P - P∩Q)

Enter the number of cups of lemonade used for 1 cup of strawberry juice.
cups
Answer:
number of cups of lemonade used = 1/3 cups
Step-by-step explanation:
number of cups of lemonade : strawberry juice
= 1 : 3
Enter the number of cups of lemonade used for 1 cup of strawberry juice.
Let
x = number of cups of lemonade used
number of cups of lemonade : strawberry juice
= x : 1
Equate both ratios to get x
1 : 3 = x : 1
1/3 = x / 1
Cross product
1*1 = 3 * x
1 = 3x
Divide both sides by 3
x = 1/3 cu
number of cups of lemonade used = 1/3 cups
