Answer:
60 marshmallows and 30 crackers
Step-by-step explanation:
Each girl brought a bag of marshmallows containing 30 marshmallows inside. 2 x 30 = 60 marshmallows altogether.
Since there are 15 s'mores, we have to distribute the marshmallows equally.
60 ÷ 15 = 4 marshmallows in each. But if we multiply that again ( 15 x 4 ) we get 60 again. Thus, they used 60 marshmallows altogether.
The girls make 15 smores. A s'more has two crackers inside one.
2 x 15 = 30 crackers.
Hope this helped.
Answer:
60 marshmallows and 30 crackers
explanation:
1. 15 x 4 = 60
60 divided by 15 = 4
2. 15 x 2 = 30
what is the solution set for 2x2+15=-11x
Answer:
2x^2+11x+15=0
factor
2x^2+6x+5x+15=0
2x(x+3)+5(x+3)=0
(2x+5)(x+3)=0
x=-3 and x=-5/2
Solve for x
A) 12
B) 13
C) 10
D) 11
Answer: A)12
Step-by-step explanation:
The line YZ must be half the size of the line QS, so double the length of YZ should be equivalent to the value of QS
2(x+2)=2x+4
Now we can set them equal to each other and solve for x
[tex]2x+4=3x-8\\2x+4+8=3x-8+8\\2x+12=3x\\2x-2x+12=3x-2x\\12=x[/tex]

Tell whether the triangle with the given side lengths is a right triangle
14mm, 19mm, 23mm
Answer:
not a right triangle
Step-by-step explanation:
The side lengths of a right triangle will satisfy the relation given by the Pythagorean theorem:
c² = a² +b²
23² = 14² +19²
529 = 196 +361
529 = 557 . . . . . . . . not true; not a right triangle
__
The longest side (23 mm) is too short for a right triangle, so the angle opposite will be smaller than 90°. This is an acute triangle.

A model house has a scale of
lin: 2ft. If the real house is 26 ft
wide, then how wide is the
model house?
Answer: Assuming that you mean 1in:2ft the model house would be 13 inches wide.
Step-by-step explanation: well 1 is half of 2 right? So if you want to get the numbers easier to use then just divide that 26 by 2 and then you get the scale 1in:1ft. From there it is easy, 13 feet of the real house= 13 inches in the model house

Answers:
a) x+y = 70b) The graph is shown below. The lines intersect at (20, 50) meaning that she has 20 quarters and 50 dimes.========================================================
Explanation:
a)
x = number of quarters
y = number of dimes
x+y = number of dimes and quarters
x+y = 70 coins total
-----------
b)
Use a graphing tool like Desmos or Geogebra to plot each linear equation on the same xy grid. I'm using Geogebra to get what is shown below.
The red line 25x+10y = 1000 goes through (0,100) and (40,0)
The blue line x+y = 70 goes through (0,70) and (70,0)
The two lines intersect at (x,y) = (20,50)
This means x = 20 and y = 50 pair up together.
Kateri has 20 quarters and 50 dimes
20 quarters = 20*25 = 500 cents = 500/100 = $550 dimes = 50*10 = 500 cents = 500/100 = $5Total value = $5 + $5 = $10
Also note that 20 quarters + 50 dimes = 70 coins total
Both conditions have been confirmed.

Answer: 34 cm^2.
Step-by-step explanation: To find the area of a trapezoid, you need to add base 1 and base 2, multiply the height, and divide it all by 1/2. The steps are done below:
Find base 1, base 2, and the height: To find base 1 and base 2, you find the top and bottom lengths of the trapezoid. 5 is the top and 12 is the bottom of the trapezoid. You can assign whichever base to whichever number, as long as base 1 and base 2 have a number. For this problem, we'll assign 5 for base 1 and 12 for base 2. To find the height, you need to find the height of the trapezoid, which is 4.Make an equation: The equation should look like the following... 5 (base 1) + 12 (base 2) x 4 (height) / 1/2.Solve: The first thing you should do when solving is to add the bases together, which is 17. Next multiply the height which is 4, by 17, which is 68. Lastly divide 68 by 2, which can be done in two ways. You can either simply divide 68 by 2 or multiply 68 by 1/2, which will both give you the same answer. 68 x 1/2 = 34.Therefore, your answer is 34 cm^2. There's an image below if you need additional information.

Look at the following solution of the equation x raised to the power of 6=64.
x raised to the power of 6=64
so, x raised to the power of 3=8
so, x=2
There is an error in this solution. Write a corrected version.
Answer:
Nothing wrong with the solution x = 2
Step-by-step explanation:
2^6 = 64
2^3= 8
Hence x = 2
In AABC, m ZA=36° and m ZB =92°. What is M
?
m∠C = 52°
The total interior angle of a triangle sum ups to 180°Solve:
m∠A + m∠B + m∠C = 180°
36° + 92° + m∠C = 180°
m∠C = 180° - 92° - 36°
m∠C = 52°
Answer:
m∠C = 52°Step-by-step explanation:
Angle Sum Property
∠A + ∠B + ∠C = 180°Here we have :
∠A = 36°∠B = 92°Solving :
36° + 92° + ∠C = 180°∠C + 128° = 180°∠C = 52°this is a k 12 question
If the spinner below is spun twice, find the probability that it lands on N, then a vowel.
Answer:
0.29 or 29%
Step-by-step explanation:
There are 7 options per spin. Of which 3 vowels.
For 2 spins, total spins is 14.
conditions:
First spin is 1/7
Second spin is 3/7
so,
4/14 = 0.29 or 29% I think

Consider the line 2x+6y= -4. What is the slope of a line perpendicular to this line? What is the slope of a line parallel to this line?
Answer:
the slope of the line perpendicular to that line is 6/2
Step-by-step explanation:
Find the slope of the original equation by putting it into y=mx + b form
2x+6y=-4 Given
2x-(2x)+6y=-4-(2x) Subtract 2x from both sides
6y= -2x -4 Simplify
6y/6= -2x/6 -4/6 Divide both sides by 6
y= -2/6 x - 4/6 Simplify
*perpendicular slopes are opposite reciprocals*
-2/6 = slope
2/6 is the opposite of -2/6
6/2 is reciprocal of 2/6
