Answer:
50%Step-by-step explanation:
what percent of 7 is 3.5
3.5 is half of 7, so 100%: 2 = 50%
Answer: 50%
I have shown two methods, both work well and can be used to solve other scenarios as well.
[Method One]
We will set up a proportion and solve.
-> A percent divided by 100 is a decimal. This means 100% = 1 in our proportion
[tex]\frac{1}{7} =\frac{x}{3.5}[/tex]
7x = 3.5
x = 0.5
0.5 * 100 = 50%
[Method Two]
We will put the whole value in the denominator, and the "what percent of" value is the numerator.
[tex]\displaystyle \frac{3.5}{7}[/tex]
0.5
0.5 * 100 = 50%

Answer & Step-by-step explanation:
USDA's Dietary Guidelines for Americans provide percent ranges for each macronutrient. For adults, the organization recommends consuming 10%–35% of calories from protein, 45%–65% from carbohydrates, and 20%–35% of calories from fat. They also suggest consuming less than 10% of total calories from saturated fat.

Step-by-step explanation:
4x4= 8
10x10= 20
8+20= 28
5x2= 10
9x2= 18
10+18= 28
Answer:
[tex]4x + 10y = 28 \\ 5x + 9y = 28 \\ 10y = 28 - 4x \\ y = \frac{28 - 4x}{10} \\ y = 2.8 - 0.4x \\ 5x + 9(2.8 - 0.4x) = 28 \\ 25.2 - 3.6x + 5x = 28 \\ 1.4x = 2.8 \\ x = 2 \\ [/tex]
[tex]y = 2.8 - 0.4 \times 2 \\ y = 2[/tex]

A 30-foot ramp is used to move product to a loading dock. The ramp makes a 24° angle with the horizontal. The ramp is to be replaced with a ramp that is 50 feet long. What angle does this replacement ramp make with the horizontal? Round your answer to the nearest tenth of a degree.
Check the picture below.
[tex]sin(\theta )=\cfrac{\stackrel{opposite}{30\cdot sin(24^o)}}{\underset{hypotenuse}{50}}\implies sin^{-1}[sin(\theta )]=sin^{-1}\left[ \cfrac{30\cdot sin(24^o)}{50} \right] \\\\\\ \theta =sin^{-1}\left[ \cfrac{30\cdot sin(24^o)}{50} \right]\implies \theta \approx 14.1^o[/tex]
The value of angle does this replacement ramp make with the horizontal is,
⇒ θ = 14.1°
What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
A 30-foot ramp is used to move product to a loading dock.
The ramp makes a 24° angle with the horizontal.
And, The ramp is to be replaced with a ramp that is 50 feet long.
Hence, By given figure;
We have;
⇒ sin θ = 30 × sin 24° / 50
⇒ θ = sin ⁻¹ (30 × sin 24° / 50)
⇒ θ = 14.1°
Thus, The value of angle does this replacement ramp make with the horizontal is,
⇒ θ = 14.1°

49 trophies on shelves + 4 leftover = 53 trophies overall
So the answer is A. 53
PLEASE HELP!!!!!!!!!!!!!!!!!!!!!
Step-by-step explanation:
the last 2 answer options are completely useless and outright nonsense, because all limits are going against +4.
so, an asymptote at x = -4 is not an option anywhere.
g(x) is always y, and the limit of the function is the limit of the y values.
we just evaluate for what x value is then y reaching that limit. but the sign of the y limit has no direct impact on the sign of the x value.
it is true that the case x = -4 needs to be checked too, but it turns out this just delivers g(-4) = 0.
now, about x = 4 :
when coming from the left side of +4 (increasing x), what is the sign of the function ?
we can simply use x = 3 to test this :
g(3) = 2(3+4)²/(3² - 16) = 2×49/-7
so, it is negative.
that means when getting closer and closer to +4 coming from that side we what get negative values, and the limit is -infinity.
when coming from the right side of +4 (decreasing x), what is the sign of the function ?
we can simply use x = 5 to test this :
g(3) = 2(5+4)²/(5² - 16) = 2×81/9
so, it is positive.
that means when getting closer and closer to +4 coming from that side we what get positive values, and the limit is +infinity.
so, the second answer option is correct.
because of these y limits, there is a vertical asymptote at x = 4 that kind of "connects" -infinity and +infinity in y direction at that location and symbolizes the limits of y.

You invested money in two funds. Last year, the first fund paid a dividend of 9% and the second a dividend of 3%, and you received a total of $858. This year, the first fund paid a 10% dividend and the second only 1%, and you received a total of $867. How much money did you invest in each fund?
The amount that was invested in the first fund is $8300.
The amount that was invested in the second fund is 3700.
What are the linear equations that represent the question?0.09a + 0.03b = $858 equation 1
0.1a + 0.01b = $867 equation 2
Where:
a = amount invested in the first fund b = amount invested in the second fund How much was invested in the second fund?Multiply equation 2 by 0.9:
0.09a + 0.009b = 780.30 equation 3
Subtract equation 1 from equation 3
0.021b = 77.70
Divide both sides by 0.021
b = $3700
How much was invested in the first fund?
Substitute for b in equation 1: 0.09a + 0.03(3700) = $858
0.09a + 111 = 858
a = (858 - 111) / 0.09
a = $8300

What is the cost of the hot dog?
What is the cost of one hamburger?pleaseeeee hellpppppp
Answer:
1 hot dog = $1.50 each
1 hamburger = $1.75 each
Step-by-step explanation:
Answer:
The prices must be $1.50 and $1.75
Step-by-step explanation:
For instance, seven hot dogs and two hamburgers cost $14: 7D+2B=14
We also know that two hot dogs and seven hamburgers cost $15.25: 2D+7B=15.25
Now, if we combine these two equations, we have a system where EVERYTHING has to be true at the same time
7D+2B=14
2D+7B=15.25
From here there are a couple trick you should know to solve a system of equation, especially substitution and elimination. I see a coefficient of 2, so I'd rather use substitution by dividing the entire first equation in half:
3.5D+B=7
Now I'll solve for B
B=7-3.5D
Now that I've solved for a variable, I can substitute the solution into the other equation
2D+7( B )=15.25
becomes
2D+7(7-3.5D)=15.25
Now I can distribute and solve for D:
2D+49-24.5D=15.25
22.5D=33.75
D=1.5
Now we can replace D from either (or both) of our original equations and see what B has to be
7(1.5)+2B=14
10.5+2B=14
2B=3.5
B=1.75
2(1.5)+7B=15.25
3+7B=15.25
7B=12.25
B=1.75
The prices must be $1.50 and $1.75. The most important part of all this is setting up the equations, the rest is just being careful with your calculations.

Step-by-step explanation:
as the triangles are congruent
The coordinate of point F is (1-, 4). Therefore, option A is the correct answer.
What is coordinate plane?A coordinate plane is a two-dimensional surface formed by two number lines. It is formed when a horizontal line (the X-axis) and a vertical line (the Y-axis) intersect at a point called the origin. The numbers on a coordinate grid are used to locate points.
From the given graph, the coordinate points are A(-5, 0), B(-5, -5) and C(2, -5).
Here, ΔABC and ΔDEF are congruent triangles.
So, the coordinate of point F are (1-, 4)

Hey! pls help me with this question on angles. would really be appreciated. have a nice day.
Using supplementary angles, it is found that the measures of the angles are given as follows:
m<a = 30º.m<b = 90º.What are supplementary angles?Supplementary angles are two angles whose sum is of 180º.
An interior angle is supplementary with it's exterior angle, hence:
m<a + 150º = 180º -> m<a = 30º.
The sum of the three interior angles of a triangle is of 180º, hence:
30º + m<b + 60º = 180º
90º + m<b = 180º
m<b = 90º.
