Age of President G.H.W. Bush is 37.
What is Unitary Method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
Age of President Bush = 54,
So, Age of President Clinton
=(54/2) + 14
=27+14
=41
Now, Age of President G.H.W. Bush
=46/2+14
=23+14
=37
Hence, the age of President G.H.W. Bush is 37.

Venetta buys 2 pounds of pistachios and 3 pounds of almonds. The pistachios cost $4 more per pound than the almonds. She pays a total of $48. Which of the following are true? Select all that apply.
A. One pound of pistachios plus 1 pound of almonds cost $20.
B. The pistachios cost twice as much per pound as the almonds.
C. Reducing the number of pounds of almonds by 1 results in a total cost of $40.
D. The cost a, in dollars, of 1 pound of almonds is modeled by 2(a – 4) + 3a = 48.
E. The cost p, in dollars, of 1 pound of pistachios is modeled by 2p + 3(p – 4) = 48.
The options that are true include:
A. One pound of pistachios plus 1 pound of almonds cost $20.
C. Reducing the number of pounds of almonds by 1 results in a total cost of $40.
E. The cost p, in dollars, of 1 pound of pistachios is modeled by 2p + 3(p – 4) = 48.
Cost of almond = a
Cost of pistachios = a + 4
Therefore, based on the information given, the equation to solve the question will be:
2(a + 4) + 3a = 48
Collect like terms
2a + 8 + 3a = 48
5a = 48 - 8
5a = 40
a = 40/5
a = 8
Almonds cost $8
Pistachios cost $12
In conclusion, the correct options are A, C, and E.

The diameter of Jupiter is about 1.4 x 10 5 kilometers. The diameter of Mars is snout 6.8 x 10 3 kilometers. About how many times greater is Jupiter’s diameter of Mars
Answer:
Jupiter's diameter is "about" 21 times greater than Mars with an exact answer of around 20.588
Step-by-step explanation:
Jupiter = 1.4 x [tex]10^{5}[/tex] = 140,000
(1.4 "plus 5 places" is how I think of it to make it easier)
Mars = 6.8 x 10³ = 6,800
To find how many times greater Jupiter is than Mars we can divide tje diameter of Jupiter by Mars:
140,000 / 6,800 = 20.588235 etc
I am not sure how far you are rounding, but Jupiter's diameter is "about" 21 times greater than Mars

In a recent year, 27.4% of all registered doctors were female. If there were 55,600 female registered doctors that year, what was the total number of registered doctors?
Answer:
The total number of registered doctors is 202,920 rounded.
Step-by-step explanation:
Solve for (x) in this equation: 27.4/100 = 55,600/(x)
You will get the following equation: (x)= (100*55,600) / (27.4) which equals 202,919.708 rounded to 202,920
To double check, you can see that 27.4% of the total given (202,920) equals the 55,600.

Step-by-step explanation:
Mao will say more numbers because, to get to 30, you must count by fives 6 times. For example, 5,10,15,20,25,30. There are 6 numbers there. On the contrary, Alana is only going to count 4 times. 10,20,30,40. 6 is greater than 4, therefore Mao will say more numbers. I hope this helps!

Answer:
<
Step-by-step explanation:
Firstly, you can focus on the scientific notation and calculate which one is bigger. The left side is [tex]10^3[/tex] whereas the right side is [tex]10^4[/tex]. This shows that even if the number before this was bigger, the larger exponent of these two are the bigger number.
[tex]10^3 = 1000\\10^4 = 10000[/tex]
Meaning the correct sign would be the smaller than sign (<) as the right side is bigger than the left.

Answer:
m < U = 65°
Step-by-step explanation:
Given that m < PTU° = 115°, and that it is a supplement to < UTV, then we can establish that m < UTV = 65° because their angles must add up to 180°.
From this point forward, we'll name < UTV as < T of △VUT.
Now that we have the measure of < T, we can find out the value of the missing angle, < VUT, through the following equation:
180° = m < V° + m < T° + m < U°
180° = m < 50° + m < 65° + x
180° = m < 115° + x
Subtract m < 115 from both sides to isolate x:
180° - m < 115° = m < 115° - m < 115° + x
65° = x
To verify that we have the correct answer, we'll add up all the measures of the three angles of the triangle to see if it sums up to 180°:
180° = m < V° + m < T° + m < U°
180° = m < 50° + m < 65° + m < 65°
180° = m < 50° + m < 65° + m < 65°
180° = 180° (True statement).
Therefore, the measure of the missing angle, < U = 65°

Three friends participated in a "Biggest Loser" weight loss competition. The table below shows their starting weight and the weight after two months:
Starting Weight
Weight After Two Months
Jacob
225 pounds
207 pounds
Timothy
200 pounds
188 pounds
Hamza
280 pounds
259 pounds
Who lost the biggest percentage of his starting weight?
You need to find the percentage of weight loss for each participant.
To find the percentage of weight loss use the formula
Starting weight – Weight after two months x 100
Starting Weight
Answer:
Jacob lost the biggest percentage of his starting weight.
Jacob: 8%
Timothy: 6.4%
Hamza: 7.5%
Formula: (initial weight - new weight)/initial weight times 100.
Step-by-step explanation:
Jacob: 225 pounds - 207 pounds = 12 pounds
x/100 = 12/225
= 1800/225
= 8%
Timothy: 200 pounds - 188 pounds = 12 pounds
x/100 = 12/188
= 1200/188
= 6.4%
Hamza: 280 pounds - 259 pounds = 21 pounds
x/100 = 21/280
= 2100/280
= 7.5%
