Answer:
50
Step-by-step explanation:
Wen: 30% of the total number of cards = 60 cards
Set this up as an equation
30/100 = 60/x
Cross multiply
30 × x = 100 × 60
30x = 6000
Divide both sides by 30 to isolate the variable
x = 200
There are 200 cards total
Gina: 25% of the total 200 cards
Set this up as an equation
25/100 = x/200
Cross multiply
25 × 200 = 100 × x
5000 = 100x
Divide both sides by 100 to isolate the variable
50 = x
Gina's share is 50 cards

If the perimeter of a rectangle garden with a width of 15 is 125, what is the perimeter of the daily record it if the scale factor is 60%
Answer:
(here i assume that the daily record is another rectangle)
For a rectangle with width W and length L, the perimeter is:
P = 2*W + 2*L
in this case we know that:
P = 125
W = 15
Replacing these in the perimeter equation we get:
125 = 2*15 + 2*L
125 = 30 + 2*L
125 - 30 = 2*L
95 = 2*L
95/2 = L = 47.5
Now we know that the daily record has a scale factor of 60%.
This means that each measure of this rectangle is (60%/100%) times the equivalent measure of the rectangle garden.
Then if the width of the daily record is W' and the length of the daily record is L'
This means that:
L' = (60%/100%)*L = 0.6*L = 0.6*47.5
W' = (60%/100%)*W = 0.6*W = 0.6*15
Then the perimeter is:
P' = 2*0.6*47.5 + 2*0.6*15 = 75
(notice that is exactly the same than multiplying the original perimeter by (60%/100%) = 0.6)

The value of x in the expression
2x/3 - 7 = 5 is
Answer:
The answer is X = 18
Step-by-step explanation:
2x/3 - 7 = 5
Multiply both sides if the equation by 3 : 2x - 21 = 15
Move the constant to the right hand side and change its sign : 2x = 15 + 21
Calculate 2x = 15 + 21
2x = 36
Divide both sides of the eqaution by 2 : 2x = 36
x = 18
Answer X = 18
Divide 1 hour in the ratio 1 : 9 : 10
3 minutes; 27 minutes; 30 minutes
0.05 minutes; 0.45 minutes; 0.5 minutes
30 minutes; 27 minutes; 3 minutes
Answer:
3 minutes; 27 minutes; 30 minutes
Step-by-step explanation:
Let the common multiplier of the given ratios be x. So, the ratios 1: 9 : 10 will become x, 9x and 10x respectively.
Therefore,
[tex]x + 9x + 10x = 1 \: hour \\ \\ 20x = 60 \: minutes \\ \\ x = \frac{60 \: minutes}{3} \\ \\ x = 3 \: minutes \\ \\ 9x = 9 \times 3 = 27 \: minutes \\ \\ 10x = 10 \times 3 = 30 \: minutes[/tex]
Thus, 1 hour in the ratio 1 : 9 : 10 can be divided as:
3 minutes; 27 minutes; 30 minutes

one angle of a triangle measures 35°. A second angle measures (3x)°, and the third angle measures 2x - 20)°. what is the value of x?
Answer:
x = 33
Step-by-step explanation:
Sum of the angles in a triangle is 180 so,
35 + 3x + 2x - 20 = 180
35 + 5x - 20 = 180
15 + 5x = 180
5x = 180 - 15
x = 165/5
x = 33
f(x) = 3x - 3
g(x) = 4x + 5
find (f+g) (3)
Answer:
23
Step-by-step explanation:
(f + g)(3) = f(3) + g(3)
f(3) = 3(3) - 3 = 9 - 3 = 6
g(3) = 4(3) + 5 = 12 + 5 = 17
Then
(f + g)(3) = 6 + 17 = 23

A restaurant small salt shakers contains 0.6 ounces of salt. The shakers are filled from a container that has 18.6 ounces of salt. If 8 shakers are filled, how much salt will be remaining in the salt container?
Answer:
13.8 ounces of salt
Step-by-step explanation:
A restaurant small salt shakers contains 0.6 ounces of salt. The shakers are filled from a container that has 18.6 ounces of salt. If 8 shakers are filled, how much salt will be remaining in the salt container?
Step 1
Note that:
1 shaker = 0.6 ounces of salt
8 shakers = x
Cross Multiply
x = 8 × 0.6 ounces of salt
x = 4.8 ounces of salt
Step 2
The shakers are filled from a container that has 18.6 ounces of salt. If 8 shakers are filled, how much salt will be remaining in the salt container?
This is calculated as:
18.6 ounces of salt - 4.8 ounces of salt
= 13.8 ounces of salt

Colton solved an equation incorrectly, as shown below:
Step 1: x - 13 = 26
Step 2: x = 26 - 13
Step 3: x = 39
Which statement best explains why Step 2 is incorrect in Colton's solution? (4
points)
He did not divide 26 by 13.
He did not multiply 26 by 13.
O He did not subtract 13 from 26.
He did not add 13 to 26.
Answer:
He didn't add 13 to 26
Step-by-step explanation:
he would need to add -13+13 to get rid of it. and add 13 on the other side 13+26
He added instead of subtracting. The answer is the first.

Probability of blue is 0.4 red 0.3 yellow 0.3 there are 30 blue cubes in box what total number of cubes in box
Answer:
75
Step-by-step explanation:
The computation of the total number of cubes in box is shown below:
Given that
The probability of blue = 0.4
For red it is 0.3
And, for yellow it is 0.3
As if there is 30 blue cubes in a box
So for red it is = 30 × 0.3 ÷ 0.4 = 22.5
And, for yellow = 30 × 0.3 ÷ 0.4 = 22.5
Now the total number of cubes in a box is
= 30 + 22.5 + 22.5
= 75
Pls help with finding slope and y intercept from 2 points‼️‼️❗️❗️❗️❗️
step 1: plot your points.
step 2: find the rise over run
step 3: place the rise over run in decimal form. say its 5 to the side and 2 up 2/5 (if it was a negative rise such as 2 down it would be -2/5)
step 4= find where it crosses the y line such ex: 0,8 it would be 8 (if it were negative it would be 0,-8: -8)
then put in y intercept form: y=2/5x+8
3(3y - 10) = 6 I need the answer please
Answer:
If you wanted to simplify the equation:
9y - 30 = 6
If you wanted to solve for y:
y = 4
Step-by-step explanation:
3(3y - 10) = 6
9y - 30 = 6
Add 30 to both sides of the equation:
9y - 30 + 30 = 6 + 30
Simplify:
9y = 6 + 30
9y = 36
Divide both sides of the equation by 9:
9y ÷ 9 = 36 ÷ 9
Cancel terms that are in both the numerator and denominator:
y = 36 ÷ 9
y = 4
Is 7 asolution for the equation 2x + 12=3x +(-2x + 5)
Answer:
No
Step-by-step explanation:
2X + 12=13x - 2x + 5
2X + 12= 11x+5
2x-11x = 5-12
-9x = -7
X = 7/9
so the answer is NO
