Answer:
Not a solution
Step-by-step explanation:
If t equals 8 in the inequality t<7, then the statement is not true. Therefore, it cannot be a solution. The symbol, <, in the inequality stands for "less than." This means if the inequality were is be written in words it would say, t is less than 7. Then, if you substituted 8 for t you could see what the inequality really meant; 8 is less than 7. This is an obviously false statement, so 8 cannot be a solution.
A bicycle ramp used for competitions is a
triangular prism. The volume of the ramp
is 313.2 cubic feet. Write and solve an
equation to find the width of the ramp.
Possible student work:
V=Bh
13.4ft
Answer:
8.7 feets
Step-by-step explanation:
As obtained frommthe diagram attached :
Base, b of triangle = 6 feets
Height of triangle, h = 12 feets
Volume of a Triangular Prism is obtained using the relation :
Base Area * Width
Base area of prism :
0.5 * base * height
0.5 * 6 * 12 = 36ft²
Width, w of the ramp =x
Volume, V = 313.2 ft³
V = base area * width
313.2 = 36 * x
313.2 = 36x
x = 313.2 / 36
x = 8.7 feets

Juan's puppy currently weighs 80 pounds. This is a 60% increase in weight from when he got her. How much did the puppy weigh originally?
By using basic meaning of percentage we got that the originally puppy's weight was 50 pounds
What is percentage?Percentage is a number or ratio expressed as a fraction of 100.
Here given that Juan's puppy currently weighs 80 pounds and his is a 60% increase in weight from when he got her.
Let's suppose original weight of puppy was x pounds
We can calculate x as
[tex]x+ \frac{60}{100} \times x=80\\\\x+ \frac{6}{10} \times x=80\\\\x+ 0.6\times x=80\\\\\\1.6x=80\\\\x=\frac{80}{1.6} \\\\x=\frac{800}{16} \\\\\\x=50[/tex]
By using basic meaning of percentage we got that the originally puppy's weight was 50 pounds .

Como calcula-se a àrea de um cubo
Answer:
Spanish:
En palabras, el área de la superficie de un cubo es el área de los seis cuadrados que lo cubren. El área de uno de ellos es un * a, o un 2. Como todos son iguales, puedes multiplicar uno de ellos por seis, por lo que el área de la superficie de un cubo es 6 veces uno de los lados al cuadrado.
Además, un cubo tiene 6 caras. El área de cada cara se encuentra elevando al cuadrado la longitud del lado. Multiplica el área de una cara por el número de caras para obtener la superficie total del cubo.
Step-by-step explanation:
English:
In words, the surface area of a cube is the area of the six squares that cover it. The area of one of them is a*a, or a 2 . Since these are all the same, you can multiply one of them by six, so the surface area of a cube is 6 times one of the sides squared.
Also, A cube has 6 faces. The area of each face is found by squaring the length of the side. Multiply the area of one face by the number of faces to get the total surface area of the cube.

Two glasses of milk and 3 snack bars have a total of 62 carbohydrates, and 3 glasses of milk and 2 snack bars have a total of 58 carbs. Determine how many carbs are in one glass of milk in one snack bar.
Step-by-step explanation:
So looking at this question, we have two variables (1 - a glass of milk; 2 - a snack bar) and two equations to use to solve for the two variables. Remember that for any number of variables, you need that same number or more equations to solve for the variables.
Let's say that a glass of milk is represented by g and a snack bar is represented by s.
So we essentially have two equations here:
4 glasses of milk + 3 snack bars = 88 carbs, or:
4g + 3s = 88
2 glasses of milk + 4 snack bars = 74 carbs, or:
2g + 4s = 74
Now that we have this, we can solve for our equations. There are two ways to do this:
SUBSTITUTION - solve for one variable, then substitute it in
Let's solve for g using the second equation. First, we'll isolate g by subtracting 4s from both sides.
2g = 74 - 4s
Next, we can divide the whole equation by 2 to solve for g.
g = 37 - 2s
Now, we can substitute this into the first equation for g and solve for s.
4g + 3s = 88
4(37 - 2s) + 3s = 88
148 - 8s + 3s = 88
148 - 5s = 88 (now subtract 88 from both sides and add 5s to both sides)
60 = 5s
s = 12
Now we can use this to solve for g in the original equation
g = 37 - 2s
g = 37 - 2(12) = 37 - 24 = 13
ELIMINATION - eliminate one variable to solve for the other, then use that to solve for the first
Let's look at our two equations
4g + 3s = 88
2g + 4s = 74
Let's eliminate the variable g first by multiplying the second question by -2.
4g + 3s = 88
-4g - 8s = -148
If we add these two equations together, we get
-5s = -60
Divide both sides by -5 and we get
s = 12
Now, we can plug s into either equation to solve for g as we did above.
Josh is selling crafts at an outdoor market. He charges $2.25 for each door hanger he has made and $3.75 for each necklace. He knows he has sold at least 20 items at the market, but he has no more than $60 in sales.
Answer:
He sold 10 hangers and 10 neclesses
Step-by-step explanation:
Given data
Let the number of door hanger be x
and the number of neckless be y
so
x+y= 20---------1
also,
2.25x+3.75y= 60---------2
Solve 1 and 2 together
From 1
x= 20-y
put this in place of x in 2
2.25(20-y)+3.75y= 60
45-2.25y+3.75y= 60
1.5y= 60-45
1.5y= 15
y= 15/1.5
y= 10
Put y= 10 in 1
x+10= 20
x= 20-10
x= 10
help please I have too many points and I also need help on my math
Answer:
Complementary
x = 55
Step-by-step explanation:
Complementary angles add up to 90°, while supplementary angles add up to 180°.
In this situation, the two angles add up to 90° (the little box means that an angle is a 90° angle) So, the angles are complementary.
Now, we can write this equation.
x + x - 20 = 90
Simplify.
2x - 20 = 90
2x = 110
x = 55
Just in case, let's check the answer.
Substitute x = 55 into (x + x - 20 = 90)
55 + 55 - 20 = 90
110 - 20 = 90
90 = 90
This is true, so x = 55 is correct.

The American Quarter Horse is the most popular riding horse in the world. The average weight of an American Quarter Horse at birth is 85 pounds. They grow to a maximum weight of 1300 pounds. Write and solve an inequality to find how many pounds an American Quarter Horse may gain from birth to adulthood.
Answer: See explanation
Step-by-step explanation:
From the question, we are informed that the average weight of an American Quarter Horse at birth is 85 pounds and that they grow to a maximum weight of 1300 pounds.
The inequality to calculate the amount of pounds that an American Quarter Horse may gain from birth to adulthood will be the difference between it's maximum weight and weight at birth. This will be:
= 1300 - 85.
= 1215 pounds
Given a set of attributes, can you make one triangle, no triangles, or many triangles?
jo says, "the attributes of my triangle are sides that are 3cm and 9cm long. I can make only one triangle because I have to connect the ends of my two sides."
do you agree or disagree? why?
Answer:
All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side. If this is true for all three combinations of added side lengths, then you will have a triangle.

question: write the function as an equation, the function is linear btw
Answer:
y - 8 = 4(x - 2)
Step-by-step explanation:
Note that as we increase any x value by 1, the corresponding y value increases by 4. Thus, the slope is 4.
Using the slope-intercept formula, we get:
y - 8 = 4(x - 2)
Check: If x = 5, does this formula result in y = 20?
y = 8 + 4(x - 2) with x = 5 comes out to y = 8 + 4(3) = 8 + 12 = 20. YES
