Each time Miranda goes to the store she plans to spend \$7$7dollar sign, 7, and each time Savannah goes to the store she plans to spend \$9$9dollar sign, 9. A few weeks from now, Miranda and Savannah are surprised to find out that they have spent the exact same total amount of money at the store. What is the least possible number of times that Miranda has been to the store
Answer:
9 visits
Step-by-step explanation:
Given that:
Amount spent by Miranda per visit = $7
Amount spent by Savanah per visit = $9
To obtain the least number of visits by Miranda ;
We obtain the L. C. M of 7 and 9, the. Divide by the amount she spends per visit ;
Multiples of :
7 = 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77
9 = 9, 18, 27, 36, 45, 54, 63, 72, 81
Hence, lowest common multiple of 7 and 9 is 63 ;
Hence, least possible. Number of visits by Miranda is ; 63 / 7 = 9 visits

Step-by-step explanation:
Carl is having a party. He has bought 24 brownies and is making 6 more batches of brownies. The inequality below can be used to determine how many brownies, b, must be in each batch so that all 138 guests get at least 1 brownie. Determine which of the given values, if any, make the inequality true: b=10, b=15, b=20 *
Answer:
b = 20
Step-by-step explanation:
The computation is shown below
Given that
24+ 6b > 138
where
b = 10
b = 15
b = 20
So if we take b = 10
= 24 + 6(10)
= 24 + 60
= 84
B = 15
= 24 + 6(15)
= 24 + 90
= 114
B = 20
= 24 + 6 (20)
= 24 + 120
= 144
So if we take b = 20 the inequality would be true

At 4:00 AM, the temperature is 12 F. If the temperature drops 3 F per hour, what will the temperature be at 6:00 AM?
Answer:
6F
Step-by-step explanation:
it is 6 f because at 4:00 a.m. it is 12 f and it drops 3 per hour and I know that 4:00 a.m. to 6:00 a.m. is 2 hours and 2 times 3 is 6 and 6 minus 12 is 6
Solve this A tourist starts off from town A and travels for 50km on a bearing of N80°W to town B.At town B ,he continues for another 40kmbon a bearing of N20°E toC. How far is C from A?
Answer:
The point C is 12.68 km away from the point A on a bearing of S23.23°W.
Step-by-step explanation:
Given that AB is 50 km and BC is 40 km as shown in the figure.
From the figure, the length of x-component of AC = |AB sin 80° - BC cos 20°|
=|50 sin 80° - 40 cos 20°|=11.65 km
The length of y-component of AC = |AB cos 80° - BC sin 20°|
=|50 cos 80° - 40 sin 20°|= 5 km
tan[tex]\theta[/tex]= 5/11.65
[tex]\theta[/tex]=23.23°
AC= [tex]\sqrt{5^2+11.65^2}=12.68[/tex] km
Hence, the point C is 12.68 km away from the point A on a bearing of S23.23°W.

In AEFG, EF = 44 centimeters and FG = 12 centimeters. Which of the following best describes the possible length, in centimeters, of
AO 44
B. O 32
CO 12
D. 32 < EG < 44
Answer:
The best inequality describes the possible length of EG is 32 < EG < 56 ⇒ B
Step-by-step explanation:
In any triangle
The sum of the lengths of any two sides must be greater than the length of the third sideThe length of any side is greater than the difference between the lengths of the other two sidesIn Δ EFG
∵ EF = 44 cm
∵ FG = 12 cm
→ Find their sum and difference
∴ The sum of their length = 44 + 12 = 56 cm
∴ The difference between their length = 44 - 12 = 32 cm
→ By using the rule above
∵ EG is the third side
∴ EG < 56
∴ EG > 32
→ Write them in one inequality
∴ 32 < EG < 56
∴ The best inequality describes the possible length of EG is 32 < EG < 56
If the correlation coefficient between two variables is .90, what percent of the variance is explained by this correlation
Answer: 81% of the variance in dependent variable is explained by this correlation .
Step-by-step explanation:
For X = Independent variable and Y=dependent variable,
If r= correlation coefficient , then we say [tex]r^2[/tex] of the variance in Y is explained by Variable X.
Given: r= 0.90
[tex](0.90)^2= 0.81[/tex]
So, 81% of the variance in dependent variable is explained by this correlation .
Consider the system of linear equations.
2y =x+ 10
3y = 3x + 15
Which statements about the system are true? Check all
that apply.
-The system has one solution.
-The system graphs parallel lines.
-Both lines have the same slope.
-Both lines have the same y-intercept.
-The equations graph the same line.
-The solution is the intersection of the 2 lines.
Answer:
-The system has one solution
-Both lines have the same y-intercept
-The solution is the intersection of the 2 lines
Step-by-step explanation:
When you graph the two lines, you get the intersection at (0,5)
The slope of one line is 0.5 and the other is 1.
The lines are not parallel because they intersect, parallel lines would never intersect.
The equations do not graph the same line, they would be one on top of the other and have infinite solutions.

Sara was making a cookies and she needs ½ cup of Chocolate chips and 2/3 cup of sugar. She accidently put in 1 cup of sugar. How many cups chocolate chips does she need now?
Answer:
3/4 cups of Chocolate chips is needed
Step-by-step explanation:
Sara was making a cookies and she needs ½ cup of Chocolate chips and 2/3 cup of sugar. She accidently put in 1 cup of sugar. How many cups chocolate chips does she need now?
From the above question:
2/3 cup of sugar = ½ cup of Chocolate chips
1 cup of sugar = x
Cross Multiply
2/3 cup of sugar × x = ½ cup of Chocolate chips × 1 cup of sugar
x = ½ cup of Chocolate chips × 1 cup of sugar/ 2/3 cup of sugar
x = 1/2 ÷ 2/3
x = 1/2 × 3/2
x = 3/4 cups of Chocolate chips
Therefore, for 1 cup of sugar , 3/4 cups of Chocolate chips is needed

-Lilly Ketchmen
Answer:
x = 2 and y = -1
Step-by-step explanation:
simplify the first equation by dividing each term by -2
x - 3y = 5
now you can add this to 4x + 3y = 5 and the 'y-values' will be eliminated and you will have:
5x = 10
x = 2
substitute '2' for 'x' to solve for 'y':
-2(2) + 6y = -10
-4 + 6y = -10
6y = -6
y = -1
