The shape has an area of 60 square inches. Find the value of x.
Answer:
The value of x is 12.
Step-by-step explanation:
Given that the area of triangle formula is A = 1/2×b×h where b represents base which is the x and h is height, 10 inches. So you have to substitute the following values into the formula :
[tex]area = \frac{1}{2} \times base \times height[/tex]
Let area = 60,
Let base = x,
Let height = 10,
[tex]60 = \frac{1}{2} \times x \times 10[/tex]
[tex]60 = 5 \times x[/tex]
[tex]5x = 60[/tex]
[tex]x = 12 \: inches[/tex]
Answer:
12 inches
Step-by-step explanation:
The area of a triangle can be found using the following formula.
a=(b*h)/2
We know that the triangle has an area of 60 inches squared. We also can see from the picture that the height is 10 inches, and the base is x inches.
a=60 inches^2
b= x inches
h= 10 inches
Substitute these values into the formula
60=(x*10)/2
Now, solve for x. To do this, get x alone. Perform the opposite of what is being done to the equation. Remember to perform everything to both sides of the equation.
x*10 is being divided by 2. The opposite of division is multiplication, so multiply both sides by 2.
2(60)=(x*10/2)2
2(60)=x*10
120=x*10
x is being multiplied by 10. The opposite of multiplication is division. Divide both sides by 10.
120/10=x*10/10
120/10=x
12=x
The base, or x, is 12 inches.

Half of a number is equal to three times the difference between 27 and 12.
Answer:
1/2x = 3*(27-12)
Step-by-step explanation:
Let x be the number
Is means equals
Difference means subtract
1/2x = 3*(27-12)
Answer:
[tex]$\frac{1}{2} x = 3(27-12)$[/tex]
or
[tex]$\frac{x}{2} = 3(27-12)$[/tex]
Step-by-step explanation:
Half of a number is equal to three times the difference between 27 and 12.
Half of a number ([tex]x[/tex]): [tex]$\frac{1}{2}x=\frac{x}{2} $[/tex]
Three times the difference between 27 and 12: [tex]3(27-12)[/tex]
[tex]$\frac{1}{2} x = 3(27-12)$[/tex]
By the way, we can find the value of [tex]x[/tex]
[tex]$\frac{x}{2} = 3(27-12)$[/tex]
[tex]$\frac{x}{2} = 3(27-12)$[/tex]
[tex]$\frac{x}{2} = 45 $[/tex]
[tex]$x = 90 $[/tex]

Multiple chickens and rabbits are in a cage. There are 20 more chickens than rabbits and together, there are 256 legs in all. How many rabbits are there? Please explain
Answer:
c = −108 and r = 118
Step-by-step explanation:
Since we know that chickens have 2 legs and rabbits have 4 legs, we can set up a system of equations to solve the problem.
Let c be the number of chickens and r be the number of rabbits.
for legs, we can write the equation out in word form as:
(number of legs per chicken)(number of chickens) + (number of legs per rabbit)(number of rabbits) = (total number of rabbits)
In algebraic form, this equation would look like this:
2 c + 4 r = 256
20+r +r = 256
Now we can use elimination (or substitution) to solve for c and r:
The equation can be reduced by dividing both sides by 2:
c + 2 r = 128
Solve for r.
20+r +r = 256
2r = 236
2r/2 = 236/2
r = 118
Substitute and solve for c.
c + 2(118) = 128
c + 236 = 128
c = -108

wimming Pool On a certain hot summer's day, 528 people used the public swimming pool. The daily prices are $1.25 for children and $2.25 for adults. The
ceipts for admission totaled $985.00. How many children and how many adults swam at the public pool that day?
mere were 159 children at the public pool.
Answer:
Step-by-step explanation:
Let the number of children = c
The number of adults = a
Total people = 528
c + a = 528 ------------------------(I)
Total price = $ 985
1.25c + 2.25a = 985 ---------(II)
Multiply equation (I) by (-1.25).
(I)*(-1.25) -1.25c - 1.25a = - 660
(II) 1.25c + 2.25a = 985 {add, c will be eliminated}
a = 325
Number of adults = 325
Plugin the value of a in equation (I)
c + 325 = 528
c = 528 - 325
c = 203
Number of children = 203
Use the table to find the constant of proportionality and the equation that represents the relationship. Let x = number of apples and y = number of slices. The constant of proportionality is _______. The equation for this relationship is _______.
THE ANSWER CHOICE IS IN THE PICTURE
Answer:
a)The constant of proportionality is 6.
b)The equation for this relationship is y=6x.
Step-by-step explanation:
a) 6/1=6
b)if apples is "x" and slices is "y," substitute y for 6 and x for 1
so 6=6(1) which is y=6x
The required constant of proportionality is 6 and the equation for this relationship is y=6x.
A table of data is given which describe the relationship between number of apples and number of slices. Blank space in statement to be filled.
The equation is a function of the relation between two or more values contains equal sign.
Here, from table the equation can be calculated as
Number of apples(x) is directly proportional to the number of slices(y). i.e.
y ∝ x
Now,
y=kx ----(1) (where k is proportionality constant)
for 1 apple the number of slices is 6 so,
6 = k*1
k = 6
Put k is equal to 6 in the equation (1).
y = 6x.
Thus, the required constant of proportionality is 6 and the equation for this relationship is y=6x.

Given that the graph is not provided, I will answer the question in general terms.
To know if a relationship is or is not a function you have to check if for every value of the dependent variable there is associated only one value of the dependent variable.
The domain of a function is composed of all the possible values that variable x (the independent variable) can take.
The range of a function is composed of all the possible values that variable y (the dependent variable) can take. That is, all the values that f(x) can assume (see picture attached).

Answer:
Step-by-step explanation:
Angles 153 and QRP are straight angles, and thus Angle QRP is
180 - 153, or 27 degrees.
The interior angles of the triangle must sum up to 180 degrees:
27 + (3y + 5) + (2y - 7) = 180.
combining like terms, we get:
5y - 25 = 180, or 5y = 155, or y = 31
Then Angle Q is 3(31) + 5, or 93
Angle P is 2(31) - 7, or 55, and
Angle QRP is 27 degrees (found earlier).

Can we combine different functions (quadratic, linear, exponential, cube root) into one piecewise function? If the answer is yes, then why?
Plzzzz help
Answer: yes, because it is useful to describe changes in the behavior of the thing we are describing.
Step-by-step explanation:
A piecewise function f(x) is a function that is "different" depending on the range of the values of x, this is for example:
y = x -----> if x < 0
y = x^2 ----- if x ≥ 0
This is used to represent changes in the behavior of the thing we are describing.
For example, suppose an object that is moving with constant velocity, the velocity graph will be a constant line.
Now, the object suddenly, at a time t = t0 accelerates to a constant acceleration A, now the graph of the velocity is a linear graph with slope equal to A.
So this situation can be represent this with a piecewise function:
V(t) = c -----> if t < t0
V(t) = c + A*t -----> if t ≥ t0
So the answer is yes, we can.
Joseph received a $20 gift card for downloading music. Each downloaded song costs $1.29. Explain how to write and solve an inequality that can be used to determine the number of songs that he can purchase. Interpret the solution.
Answer:
There is 20 dollars and the cost is 1.29. You need to have more money than the cost
To see if he can buy Y many songs

2x^2 - 28 = x^2 + 15
What is the answer!
Answer:
x = ± sqrt(43)
Step-by-step explanation:
2x^2 - 28 = x^2 + 15
Subtract x^2 from each side
2x^2-x^2 - 28 = x^2-x^2 + 15
x^2 -28 = 15
Add 28 to each side
x^2 - 28 +28= 15+28
x^2 = 43
Take the square root of each side
sqrt(x^2) = ± sqrt(43)
x = ± sqrt(43)
