The average temperature of the earth's stratosphere is -70 degrees. The average temperature on the earth's surface is 57 degree. How much warmer is the average surface of the earth than the stratosphere?
Answer:127
all you do is subtract -70 by 57 and it will give you a negative but get rid of it and you get 127 or just take the - away from -70 and add 57
Last week, Makayla took 8 express bus rides, which cost her $34. Which equation models the cost in dollars, c, per express bus ride, b.
Based on the cost of the bus rides in total and the number of buses taken, the relevant equation would be c = 34/b.
Makayla took 8 express bus rides and this cost her $34 in total. The cost of each bus ride is therefore:
= Total cost of rides / Number of rides taken
With the cost per ride being c and the bus ride being b, the equation would be:
c = 34/b
In conclusion, to find the cost of each bus ride, use the equation c = 34/b.

Answer:
The answer is B) 2/3x=5 and E) 6x-3+8=11.
Step-by-step explanation:
Basically, all we have to do is see which of the answer options contains an equal sign. So lets go from there:
Does A have an equal sign? We can see the plus sign, a coefficient, and a variable, but we don't have an equal sign, so A is not an equation.
What about B? Well, we can see an equal sign that is showing that two values of an expression equal each other, so yes, B is an equation.
What about C? Well, we can see the minus sign, a variable, and a coefficient, but there is no equal sign. Therefore C is not an equation.
What about D? Well, D has parenthesis, variables, coefficients, and a plus sign, but no equal sign. So no, D is not an equation.
Finally, is E and equation? Well, we can see that there are two values that are equal to each other as is shown by an equals sign. So yes, E is an equation.

henrik is shopping at a store. The store is having a sale on all items henrik also has a coupon for an additional amount off the sale price.
The expression 0.7p-15 represents the final price, In dollars, of items with a regular price of p dollars. Complete the table by filling in the value of the coupon and the percent discount of the store's sale
The amount of the coupon is $30 which gives a discount of 60%.
Regular price of item = p
Final price paid by the buyer = 0.7p - 15
Discount = Regular price - Price paid by the buyer
Discount = p - (0.7p - 15)
Discount = p - 0.7p - 15.
p - 0.7p = 15
0.3p = 15.
Price = 15/0.3
Price = $50
Therefore, the amount paid by the person will be:
= 0.7p - 15
= 0.7(50) - 15
= 35 - 15
= 20
Therefore, the discount will be:
= 50 - 20 = 30
Discount percentage = 30/50 × 100 = 60%

If x2 + y2 = 14 and xy = 5, find the value of (1/2 x + 1/2 y)2.
Answer:
(½x+½y)²=6
Step-by-step explanation:
x^2 + y^2 = 14, xy=5
(A+B)^2=A^2 +2AB+B^2... (*)
(1/2x+1/2y)^2 =(*)
(1/2x)^2 +2(1/2x)(1/2y)+(1/2y)^2 =
1/4x^2 +1/2xy+1/4y^2=
1/4(x^2 +y^2) +1/2(xy)=
1/4*14+1/2*5=
14/4+5/2=
14/4+10/4=
24/4=6
let me know if I'm wrong.
( 1/2x +1/2y)²
= { ( x + y )/ 2xy }²
= ( x² + 2xy + y² )/4(xy)² —(1)
As we know that x² + y² = 14 — (2)
and xy = 5 —(3)
So, substitute the value of equation 2 and 3 in equation 1,
= ( x² + 2xy + y²)/4(xy)²
=( 14 + 2*5)/(4*5²)
= 24/(4*25)
= 6/25.

Find the vertex of a quadratic function written in standard form.
f(x) = 3x2 + 18x + 32
PLS HELP!!
Answer:
our vertex for f(x) = 3x² + 18x + 32 = (-3, 5 )
Step-by-step explanation:
let me write the standard form of a quadratic equation
[tex]a {x}^{2} + bx + c[/tex]
Now let me rewrite the original equation
[tex]3 {x}^{2} + 18x + 32[/tex]
Now we use this simple formula to find the vertex (h, k)
[tex]x = h = - \frac{b}{2a} \\ = - \frac{18}{2(3)} = - \frac{18}{6} = - 3 \\ h = - 3[/tex]
substitute -3 for x back into our original equation to solve for y our k value of our vertex
[tex]y = 3 ({ - 3})^{2} + 18( - 3) + 32 \\ = 3(9) - 54 + 32 \\ = 27 + 32 - 54 \\ = 59 - 54 \\ k = 5[/tex]
our vertex for f(x) = 3x² + 18x + 32 = (-3, 5 )
[tex](1+sin^{2} )cosx+(1+cos^{2} x)sinx=1=sin2x[/tex]
The answer is = 1 + sin x
Explanation
we need
a^2 - b^2 = (a+b) (a-b)
we use
cos^2 x + sin^2 x = 1
cos^2 x = 1 - sin^2 x = ( 1 + sin x) ( 1 - sin x )
therefore
cos ^2 x over 1 - sin x = 1+ sin x

Well….

Jane Rogers has a $100,000 whole life policy. What will the cash value of her policy be at the following anniversary dates?(Use a thousands comma where applicable.)Anniversary dateCash Value10 year$20 year$
Answer:
Brainliest Please
Step-by-step explanation:
10 year: $1000000
20 years: $2000000
Answer:
10 years = 8,900.00.
20 years = 23,200.00.
Step-by-step explanation:
Hey, let me tell you how to solve this; I had trouble as well.
Since the policy is worth 100,000, you divide this by 1,000.
That gives us 100.
Now, multiply 100 by the 10 yr cash value, which is 89.
That results in 8,900.00.
Taking 100 again, multiply it by the 20 yr cash value, 232.
That gives us 23,200.00.
Hope it helps.
