A pair of snow boots at an equipment store in Big Bear that originally cost $80 is on sale for $56. What is the rate of discount?
Answers
Divide the sale price by the original price:
56 / 89 = 0.7
Multiply by 100:
0.7 x 100 = 70%
The sale price is 70% of the original price, so the discount would be 30% (100-70= 30)
2a+3/2 - a-2/3 = a-1/4
Answers
Answer:
No solutions
Step-by-step explanation:
[tex]2a+\dfrac{3}{2}-a-\dfrac{2}{3}=a-\dfrac{1}{4}\\a+\dfrac{5}{9}=a-\dfrac{1}{4}\\\dfrac{5}{9}=\dfrac{1}{4}[/tex]
This equation has no solutions. Hope this helps!
Answer:
No solution
Step-by-step explanation:
2a+3/2 - a-2/3 = a-1/4.
2a- a +3/2 - 2/3 = a-1/4. Add like terms
a + 5/6 = a - 1/4. Variables and numbers on diferent sides
-a. -5/6. -a. -5/6
0 = -13/12
No solution because there are no a's that can make the equation true

Answers
Answer:
Plug the ordered pair (2,5) into the given equation, if it makes the equation true, then it is a solution.
Step-by-step explanation:
y = 2x + 3
substituting : 5 = 2(2) + 3
5 = 4 + 3
5 = 7, this is false, therefore (2,5) is NOT a solution
Answer:
A linear equation's solution would be a coordinate when the value of x and y satisfies the equation.
For Example:
[tex](1,7)[/tex] will be a solution to the equation [tex]y=3x+4[/tex], because if you replace x and y with one and seven it satisfies the equation.
[tex]y=3x+4\\y=7 \\x=1\\\text {Solve: }\\7=3(1)+4\\\rightarrow3*1=3\\7=3+4\\\boxed {7=7}[/tex]
[tex](1,7)[/tex] also lies on the equation's line.

Step-by-step explanation:
21. 136° and b are supplementary, meaning they have a sum of 180°. This means that 136° + b = 180° → b = 44°.
22. Again, the angles are supplementary which means that 61° + b = 180° → b = 119°.
23. Again, they are supplementary which means that x - 22° + 135° = 180° → x + 113° = 180° → x = 67°.
24. I'm pretty sure you get the gist of this. 6x + 3° + 87° = 180° → 6x + 90° = 180° → 6x = 90° → x = 15°

Assume that the hay fever rate in each age group has an approximately normal distribution. Do the data indicate that the age group over 50 has a lower rate of hay fever? Use α =0.05. If , will you reject or fail to reject the null hypothesis? Are the data statistically significant at confidence level α?
a
Since the P-value is less than the level of significance, the data are statistically significant. Thus, we fail to reject the null hypothesis.
b
Since the P-value is greater than the level of significance, the data are statistically significant. Thus, we reject the null hypothesis.
c
Since the P-value is less than the level of significance, the data are not statistically significant. Thus, we reject the null hypothesis.
d
Since the P-value is less than the level of significance, the data are not statistically significant. Thus, we fail to reject the null hypothesis.
e
Since the P-value is less than the level of significance, the data are statistically significant. Thus, we reject the null hypothesis.

O A. Area of the base
B. Perimeter of the base
C. Length of the base
O D. Volume of the base
Answers
Answer:
A.Area of the base
Step-by-step explanation:
these is obtained by multiplying the length and width of the base to get the area of the base
The variable B in the Formula is area of Base.
What is Volume?Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.
Pyramid volumes are measured by how much space they take up or by how many unit cubes can fit inside of them. A pyramid is a polyhedron because it has polygonal faces.
As, Volume of pyramid = (1/3) (Bh), where
B = Area of the base of the pyramid
h = Height of the pyramid.
So, B in the Formula is area of Base.
