Q11: 4, Q12: 40
Step-by-step explanation:
m=4 and the point is (3,10), what is the correct substitution (y=mx+b) and the value of b? a. 3=10(4)+b; b=11 b. 10=3(4)+b; b=12 c. 10=4(3)+b; b=-2 d. 10=4(3)+b; b=3
Answer:
c. 10=4(3)+b; b=-2
Step-by-step explanation:
When given a single point (x1, y1)
The Equation of a line formula is given as:
y - y1 = m(x - x1)
From the question
m=4
the point is (3,10),
Hence, Equation of the line is
y - 10 = 4(x - 3)
y - 10 = 4x - 12
y = 4x - 12 + 10
y = 4x - 2
Hence, the correct substitution (y=mx+b)
10 = 4(3) + b
b = -2
Option C is the correct option

The area of a rectangular tabletop is 24 ft.^2 lThe length of the table is 2
longer than its width. Which equation could be used to find the width (w) of the tabletop?
0 24 = 2 + 2
O 24 = +
O 24 - 22
O 24 = 22 + 2
Answer:
The equation required to find Width of rectangle is: [tex]\mathbf{24=2x+2}[/tex]
Step-by-step explanation:
Area of rectangular table top = 24 ft^2
Let width of table = x
Length of table = x+2
We need to find equation that could be used to find the width (w) of the table top?
The formula used is: [tex]Area\:of\:rectangle=Length \times Width[/tex]
Putting values in formula and finding the equation:
[tex]Area\:of\:rectangle=Length \times Width\\24=x+x+2\\24=2x+2\\[/tex]
So, the equation required to find Width of rectangle is: [tex]\mathbf{24=2x+2}[/tex]

Anthony found a sweater on sale for 15% off! The discount price of the sweater before tax is $22.74. What is the regular price of the sweater before the discount?
9514 1404 393
Answer:
$26.75
Step-by-step explanation:
The after-discount price is 85% of the original price. So, the original price is ...
0.85 × p = 22.74
p = 22.74/0.85 = 26.75 . . . . . divide by the coefficient of p
The regular price is $26.75.

if a+b=30 and a^2+b^2=740 find the value of ab
Step-by-step explanation:
HERE,
a+b=30
a^2+b^2=740
we know that,
[tex]\tt{(a+b)^2=a^2+b^2+2ab }[/tex]
according to the question,
[tex]\tt{ (30)^2=740+2ab }[/tex]
[tex]\tt{900=740+2ab }[/tex]
[tex]\tt{ 2ab=900-740 }[/tex]
[tex]\tt{ ab=\dfrac{160}{2} }[/tex]
[tex]\tt{ab=80 }[/tex]
#quality answer
the value of ab is 80
Answer:
Solution given:
(a+b)=30....(1)
a²+b²=740......(2)
squaring equation 1:
we have;
formula:
(a+b)²=a²+b²+2ab
use this formula:
(a+b)²=30²
a²+b²+2ab=30²
Substituting value of a²+b²=740
740+2ab=30²
take constant term on one side.
2ab=30²-740
subtract :30²-740
2ab=160
divide both side by 2
2ab/2=160/2
we get:
ab=80
the value of ab is 80
Do you practice is yoga for the same amount of time every day after he practices yoga for 18 minutes on Saturday he finished 24% of his daily yoga practice how many more minutes do you still practice yoga on Saturday
Answer:
51 minutes
Step-by-step explanation:
Let the total number of minutes required for daily yoga practice = x
Hence:
24% of x = 18 minutes
24/100 × x = 18 minutes
24x /100 = 18 minutes
Cross Multiply
24x = 100 × 18 minutes
x = 1800 minutes/24
x = 75 minutes.
The total number of minutes for daily yoga practice = 75 minutes
How many more minutes do you still practice yoga on Saturday?
This is calculated as:
75 minutes - 24 minutes
= 51 minutes
In the figure, each cube has a volume of 1 cubic unit. Find the volume of the figure and the area of its base.
A rectangular prism is made up of cubes. The length of the prism is 4 units, width is 3 units, and height is 3 units.
Answer:
the volume is 36 and the area of its base is 12
Step-by-step explanation:
volume = 4x3x3 = 36
area of base = 4x3=12 (do not include height)
The area of the base and the volume of the prism are 24 cubic units and 8 square units.
To find the volume of the rectangular prism, you can multiply its length, width, and height together.
In this case, the length is 4 units, the width is 2 units, and the height is 3 units.
Volume = Length x Width x Height
Volume = 4 units x 3 units x 3 units
Volume = 24 cubic units
Therefore, the volume of the rectangular prism is 36 cubic units.
To find the area of the base, you need to consider that the base is a rectangle with a length of 4 units and a width of 3 units.
Area of the Base = Length x Width
Area of the Base = 4 units x 2 units
Area of the Base = 8 square units
Therefore, the area of the base of the rectangular prism is 12 square units.
Hence the area of the base and the volume of the prism are 24 cubic units and 8 square units.

The measure of angle ZABD is 106°, the correct option is D.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
We are given that;
The line AE and CD
Now,
The angle sum property to find angle D:
Z + A + B + D = 360° Substitute the given values:
Z + 32 + 58 + D = 360 Simplify:
Z + D = 270 Subtract Z from both sides:
D = 270 - Z
Now, you need to find angle Z. To do that, you can use the fact that opposite angles in a quadrilateral are supplementary, meaning they add up to 180°2. So, angle Z and angle C are supplementary:
Z + C = 180°
You can use the fact that C is an exterior angle of triangle YZX and it is equal to the sum of the opposite interior angles3. Therefore, C = Y + X. Substitute this value:
Z + Y + X = 180°
You are given that Y = 10° and X = 6°. Substitute these values:
Z + 10 + 6 = 180 Simplify:
Z = 164
Now, you can use this value to find angle D:
D = 270 - Z Substitute Z = 164:
D = 270 - 164 Simplify:
D = 106
Therefore, by algebra the answer will be 106°.

Ms. Sampson is replacing the tile along the edge of her kitchen counter. The edge piece is LaTeX: \frac{1}{6}1 6 feet tall and LaTeX: 2\frac{3}{4}2 3 4 feet wide. What is the area, in square feet, of the edge piece?
Answer:
11/24 square feet
Step-by-step explanation:
Area of the edge piece = Length * Width
Given
Length = 1/6 feet
Width = 2 3/4 feet
Area of the edge piece = 1/6 * 2 3/4
Area of the edge piece = 1/6 * 11/4
Area of the edge piece = 11/(6*4)
Area of the edge piece = 11/24
Hence the area of the edge piece is 11/24 square feet

Step-by-step explanation:
Answer:

The subject of the formula below is y.
a=4x/t - p
Rearrange the f make x the subject.
Answer:
x = t(a+p)/4
Step-by-step explanation
Given the expression
a=4x/t - p
We are to make x the subject of the formula
a=4x/t - p
Add p to both sides
a+p = 4x/t - p+p
a+p = 4x/t
Cross multiply
t(a+p) = 4x
Rearrange
4x = t(a+p)
Divide both sides by 4
4x/4 = t(a+p)/4
x = t(a+p)/4
