Jolinda scores 21 points during her basketball game. Her team scores a total of 28 points. What fraction of the team’s points does Jolinda score? Choose the answer in simplest form.
Answer:
[tex]\frac{3}{4}[/tex]
Step-by-step explanation:
If Jolinda scored 21 points of 28 total, the fraction is:
[tex]\frac{21}{28}=\frac{3}{4}= 0.75(or75\%)[/tex]
Remember that a fraction is the representation of a portion among the total.
In addition, this fraction also would represent the effectiveness of Jolinda, we could say that she is able to score a 75% of team's points.

solve the system by substitution
2x-y+z=-4
z=5
-2x+3y-z=10
To solve the system by substitution, substitute the value of z in the equations and solve them simultaneously.
Explanation:To solve the system by substitution, we need to substitute the value of z in the other equations. Given that z=5, we can substitute this value in the first and third equations:
2x - y + 5 = -4
-2x + 3y - 5 = 10
Now, we can solve these two equations simultaneously to find the values of x and y.
To solve a system of equations by substitution, express one variable in terms of the other and substitute it into the other equations to eliminate that variable before solving for the remaining variables.
Explanation:To solve this system of equations by substitution:
Start by expressing one variable in terms of the other variable from one of the equations. In this case, we can express z as 5 since it is given.Substitute the value of z into the other two equations to eliminate the variable z.Solve the resulting system of equations for the remaining two variables.By following these steps, you can find the values of x, y, and z that satisfy the system of equations.

A) 4/7
B) 7/10
C) 4 1/7
D) 4 7/10
Answer:
D) 4 7/10
Step-by-step explanation:
Any fraction may be written as a mixed number. This type of number is formed by one or more whole parts plus a fractional part.
4.7 = 4 + 0.7
4 + 7/10
4 7/10
Following this same reasoning we can turn a mixed number into improper fraction and improper fraction into mixed number.
Kyle is converting 13°F to °C. His work is shown. Is Kyle's answer correct? If not, find his mistake and determine the correct answer to the nearest degree. Given: 5 9 (°F − 32) Step 1: 5 9 (13°F − 32) Step 2: 5 9 (45) Step 3: 25° C
Given:
The temperature is given in Fahrenheit (13 degree F).
To Find:
The correct temperature in Celsius.
Answer:
The temperature in Celsius is approximately -11 degree C.
Kyle has got an incorrect answer because instead of subtracting 32 form the temperature, he has added it.
Step-by-step explanation:
Any temperature can be changed from F to C by using the formula
[tex]C=(\frac{5}{9})(F-32)\\\\C=\frac{5(F-32)}{9}[/tex]
So, we will convert the given temperature in F to C by performing three simple steps.
Step 1 - We will subtract 32 from the Fahrenheit temperature.
Step 2 - Multiply this number by 5.
Step 3 - Divide the resulting number by 9.
So,
Step 1: 13-32 = -19
Step 2: -19*5 = -95
Step 3: -95/9 = -10.55 approx
Thus, the temperature in Celsius is approximately -11 degree C.
Kyle has got an incorrect answer because instead of subtracting 32 form the temperature, he has added it.
Kyle has got an incorrect answer because instead of subtracting 32 form the temperature, he has added it.
Given:
Kyle is converting 13°F to °C.
The formula used to convert F to C is
C= 5/9 (F- 32)
Now, Substitute F= 13 into the formulas as
C= 5/9 (13 - 32)
C = 5/9 (-19)
C= -95/ 9
C= -10.55
Thus, the temperature in Celsius is -11 degree C.

The measurement of the complement of an angle exceeds the measure of the angle by 25%. Find the measurement of the angle and its complement.
The angle measures 40 degrees, and its complement, which is 25% larger than the angle, measures 50 degrees. This is solved using elementary algebra by setting up an equation with the angle as 'x' and its complement as '90-x', and then simplifying the equation to solve for 'x'.
Explanation:The question involves finding the measure of an angle and its complement when given that the complement exceeds the measurement of the angle by 25%. To solve this, let's use algebra. Let the measure of the angle be x degrees.
Since the complement of an angle adds up to 90 degrees with the angle itself, the complement can be represented as 90 - x degrees. According to the problem, the complement is 25% more than the angle, so we can write the equation:
90 - x = x + 0.25x
Simplifying, we get:
90 - x = 1.25x
90 = 2.25x
Dividing both sides by 2.25 gives us the measure of the angle x:
x = 40 degrees
Since the complement is 90 - x, we find:
Complement = 90 - 40 = 50 degrees
Therefore, the angle measures 40 degrees, and its complement measures 50 degrees.

A solid right pyramid has a square base with an edge length of x cm and a height of y cm. Which expression represents the volume of the pyramid?
The correct expression representing the volume of the pyramid is:
[tex]\[ \frac{1}{3} \times x^2 \times y \[/tex]. Therefore the correct option is 2.
The volume [tex]\( V \)[/tex] of a pyramid is given by the formula:
[tex]\[ V = \frac{1}{3} \times \text{Base Area} \times \text{Height} \][/tex]
For a square pyramid, the base area is given by [tex]\( \text{Base Area} = \text{side length}^2 \)[/tex].
In this case, the side length is [tex]\( x \)[/tex] and the height is [tex]\( y \)[/tex]. Therefore, the expression for the volume [tex]\( V \)[/tex] is:
[tex]\[ V = \frac{1}{3} \times x^2 \times y \][/tex]
Now, let's compare this with the given options:
1. [tex]\( \frac{1}{3}xy \)[/tex] cm³
2. [tex]\( \frac{1}{3}x^2y \)[/tex] cm³
3. [tex]\( \frac{1}{2}xy^2 \)[/tex] cm³
4. [tex]\( \frac{1}{2}x^2y \)[/tex] cm³
Now, we can see that the correct expression representing the volume of the pyramid is:
[tex]\[ \frac{1}{3}x^2y \, \text{cm}^3 \][/tex]
So, the correct option is option 2: [tex]\( \frac{1}{3}x^2y \)[/tex] cm³.
The correct expression representing the volume of the pyramid is:
[tex]\[ \frac{1}{3} \times x^2 \times y \[/tex]

y =
Answer-
[tex]\boxed{\boxed{y^{\circ}=26^{\circ}\ 45'}}[/tex]
Solution-
As the triangle ABC is an isosceles triangle, with AC = BC.
So the angles A and B will be same, i.e
[tex]\Rightarrow \angle A=\angle B[/tex]
[tex]\Rightarrow 34^{\circ}=(x-5)^{\circ}[/tex]
[tex]\Rightarrow x^{\circ}=34^{\circ}+5^{\circ}[/tex]
[tex]\Rightarrow x^{\circ}=39^{\circ}[/tex]
As sum of all angles in a triangle is 180°, so
[tex]\Rightarrow \angle A+\angle B+\angle C=180^{\circ}[/tex]
[tex]\Rightarrow 34^{\circ}+39^{\circ}+4y^{\circ}=180^{\circ}[/tex]
[tex]\Rightarrow 4y^{\circ}=180^{\circ}-34^{\circ}-39^{\circ}[/tex]
[tex]\Rightarrow 4y^{\circ}=107^{\circ}[/tex]
[tex]\Rightarrow y^{\circ}=\dfrac{107^{\circ}}{4}[/tex]
[tex]\Rightarrow y^{\circ}=26.75^{\circ}[/tex]
[tex]\Rightarrow y^{\circ}=26^{\circ}\ 45'[/tex]
