Mya buys 4 pounds of turkey and 2 pounds of ham.she pays a total of $30,and the turkey cost $1.50 less than the ham.what would be the combined cost of 1 pound of ham and 1 pound of turkey?
Answer:$10.50
Step-by-step explanation:
Let t = cost per pound of turkey
Let h = cost per pound of ham
4t + 2h = 30
t = h - 1.5
substitute h-1.5 in place of t in 1st equation
4(h-1.5) + 2h = 30
4h - 6 + 2h = 30
6h - 6 = 30
6h = 36
h = 6
t = h-1.5 = 4.5
1 pound of turkey costs $4.50
1 pound of ham costs $6.00
----------
cost of 1 pound each $10.50

What shape is produced when slicing a right rectangular prism perpendicular to
the base?
Answer:
rectangle
Step-by-step explanation:
If the slice is perpendicular to the base, it can intersect at most two lateral faces and the parallel base. Hence the shape produced will be a rectangle.

According to Teo's bread recipe, he should bake the bread at 190°C for 30 minutes. His oven measures temperature in °F. To what temperature in °F should he set his oven?
Answer:
374 °F
Step-by-step explanation:
Data obtained from the question include the following:
Temperature (°C) = 190 °C
Temperature (°F) =?
Recall:
The conversion scale of temperature from °F to °C is given by the following equation:
C = 5/9(F – 32)
Next, we shall make F the subject of the formula. This can be obtained as follow:
C = 5/9(F – 32)
Cross multiply
5(F – 32) = 9C
Divide both side by 5
F – 32 = 9C/5
Rearrange
F = 9C/5 + 32
With the above formula, we can convert 190 °C to °F as follow:
Temperature (°C) = 190 °C
Temperature (°F) =?
F = 9C/5 + 32
F = 9 × 190/5 + 32
F = 1710/5 + 32
F = 342 + 32
F = 374 °F
Therefore, Teo will set the oven to 374 °F

A bird flies from the bottom of a canyon that is 51 3/10 feet below sea level to a nest that is 737 1/10 feet above sea level.
Answer:
The bird would have to fly up 685.8 feet up.
Step-by-step explanation
If we are talking about how much the bird wants to fly up to the nest, then it would be 685.8 ft up.
first,
you take the fractions which are (-51 3/10) and (737 1/10)
Then we make them decimals to be easier (on my pov) Then we have
-51.3 and +737.1
Next we add 737.1+(-51.3)
which equals 685.8 feet.
7 Car A uses petrol at the rate of 4.8L/100 km, whereas car B uses it at a rate of
10L/100 km. What will the difference in petrol costs be in a year in which both
cars travel 30000 km, if the petrol costs on average $1.45/L?
Step-by-step explanation:
30,000 km × (4.8 L / 100 km) × ($1.45 / L) = $2088
30,000 km × (10 L / 100 km) × ($1.45 / L) = $4350
The difference is $4350 − $2088 = $2262.

An $80.00 coat is marked down 20%. It does not sell, so the shop owner marks it down an additional 15%. What is the new price of the coat in dollars?
Answer:
$54.40
Step-by-step explanation:
First, find the new price after the 20% markdown:
80(0.8)
= 64
Then, find the price with the 15% markdown:
64(0.85)
= 54.4
So, the new price of the coat is $54.40

Solve for w. |w-3|+8=24 one of the answers i know is 19 If there is more than one solution, separate them with commas. If there is no solution, click on "No solution". PLZ HELP
Answer:
w = 19 or w = -13
Step-by-step explanation:
Solve for w over the real numbers:
abs(w - 3) + 8 = 24
Hint: | Isolate terms with w to the left hand side.
Subtract 8 from both sides:
abs(w - 3) = 16
Hint: | Eliminate the absolute value.
Split the equation into two possible cases:
w - 3 = 16 or w - 3 = -16
Hint: | Look at the first equation: Solve for w.
Add 3 to both sides:
w = 19 or w - 3 = -16
Hint: | Look at the second equation: Solve for w.
Add 3 to both sides:
Answer: w = 19 or w = -13
A line has a slope of 9 and passes through the point (1,5). What is its equation in
slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
y= 9x -4
Step-by-step explanation:
Please see attached picture for full solution.
The integers here are 9 and -4.
There isnt a need to use fractions in this case and hence I did not write the integers into a fraction (e.g. -4 into [tex] \frac{ - 4}{1} [/tex]) since the question requires them to be in the simplest form.
∠A and \angle B∠B are vertical angles. If m\angle A=(3x-30)^{\circ}∠A=(3x−30) ∘ and m\angle B=(2x-9)^{\circ}∠B=(2x−9) ∘ , then find the value of x.
Answer:
x = 21
Step-by-step explanation:
Vertical angles are congruent, this
3x - 30 = 2x - 9 ( subtract 2x from both sides )
x - 30 = - 9 ( add 30 to both sides )
x = 21

[tex]V=nr^{2}h\\\frac{V}{nh}=\frac{nr^{2}h }{nh}\\\frac{V}{nh}=r^{2}\\\sqrt{\frac{V}{nh} }=\sqrt{r^{2} }\\r=\sqrt{\frac{V}{nh} }[/tex]
Use the figure to the right to find the value of PT. T is the midpoint of PO.
PT = 4x + 7 and TQ = 8x - 5
PT=
(Simplify your answer.)
Answer:
PT=19
Step-by-step explanation:
It is given that, T is the midpoint of PQ. If T is mid point, then it will bisect the line segment i.e.
PT=TQ
4x + 7=8x - 5
Subtracting 7 both sides
4x + 7-7=8x - 5-7
4x=8x-12
Subtracting 8x both sides
4x-8x=8x-12-8x
-4x=-12
4x=12
x=3
The value of x is 3.
Now,
PT = 4x + 7
= 4(3) + 7
=12+7
=19
Therefore, the length of PT is 19.
If B is the midpoint of line segment AC, AB=20, and BC=4x-4, find x.
Answer:
x = 6
Step-by-step explanation:
B is the midpoint of AC. So, the length of AB equals length of BC
BC = AB
4x - 4 = 20 {add 4 to both sides}
4x -4 + 4 = 20 + 4
4x = 24 { divide both sides by 4}
4x /4 = 24/4
x = 6

Stella rewrites −212+3.7 as 3.7−212. Which property did she use? A. Additive Identity Property B. Additive Inverse Property C. Commutative Property D. Distributive Property
Answer:
Option C.
Step-by-step explanation:
It is given that Stella rewrites −212+3.7 as 3.7−212.
We need to find which property did she use.
According to commutative property of addition,
[tex]A+B=B+A[/tex]
Where, A and B are any real values.
In the given expression −212+3.7, A=-212 and B=3.7.
Using commutative property of addition, we get
[tex](-212)+3.7=3.7+(-212)[/tex]
[tex](-212)+3.7=3.7-212[/tex]
So, she used commutative property.
Therefore, the correct option is C.

Step-by-step explanation:
x-2y = 4
7x + 2y = 8
We will solve the equations using the substitution method so we will solve for y in one of the equations and and substitute it into the other equation to solve for x.
x - 2y = 4
-x -x
-2y = 4 - 1x Divide both sides by -2
y = 1/2 x - 2 Now use substitution
7x + 2( 1/2x -2) = 8
7x + 1x - 4 = 8
8x -4 = 8
+4 +4
8x = 12
x = 12/8 and simplifies to 3/2
the value of x is 3/2 so plot it into one of the equations and solve for y.
7(3/2) + 2y = 8
21/2 + 2y = 8
-21/2 -21/2
2y = -5/2
y = -5/4

Answer:
2 19/24 feet
Step-by-step explanation:
14 5/8 = 14 15/24
17 5/12 = 17 10/24 ==> 16 34/24
16 - 14 = 2
34/24 - 15/24 = 19/24
Answer = 2 19/24 feet
