Find the missing number to make these fractions equal.
Answer:
66/8 = 3/4Step-by-step explanation:
Let the unknown number be x
[tex]\frac{3}{4} = \frac{x}{8} \\\\Cross \: Multiply\\4\times x = 3 \: \times 8\\\\4x =24\\\\Divide \:both\:sides \:of\:the\:equation\: by\: 4\\\frac{4x}{4} = \frac{24}{4} \\\\x = 6[/tex]
Answer:
6
Step-by-step explanation:
Given
[tex]\frac{3}{4}[/tex] = [tex]\frac{?}{8}[/tex]
The 4 on the denominator is multiplied by 2 to obtain 8
The same operation must be applied to the numerator to make them equal.
Thus
3 × 2 = 6
[tex]\frac{3}{4}[/tex] = [tex]\frac{6}{8}[/tex] ← are equal fractions
a mouse runs across a 5.56 m kitchen floor in 3.42 seconds.What is the velocity of the mouse?
Answer:
v = 1.62 m/s
Step-by-step explanation:
Given that,
Distance covered by the mouse is 5.56 m is in 3.42 seconds.
We need to find the velocity of the mouse. It is equal to the total distance covered divided by time taken. So,
[tex]v=\dfrac{d}{t}\\\\v=\dfrac{5.56\ m}{3.42\ s}\\\\v=1.62\ m/s[/tex]
So, the velocity is 1.62 m/s.
x-intercept: 3
y-intercept: 2
Answer:
y = -2/3x + 2
Step-by-step explanation:
Hey there!
Well since we already got the y-intercept to find slope we'll use the points,
(3,0) and (0,2).
Formula: [tex]\frac{y^2 - y^1}{x^2 - x^1}[/tex]
Plug in the given points,
[tex]\frac{2 - 0}{0 - 3}[/tex]
Slope = -2/3
Slope-intercept: y = -2/3x + 2
Hope this helps :)
Answer:
y = -2/3x + 2 or
2x + 3y = 6 (standard form).
Step-by-step explanation:
I am assuming you want the equation of the straight line that passes through these 2 points.
The 2 points are (3, 0 ) and (0, 2).
The slope of the line = (2 - 0) / (0 - 3)
= -2/3.
The equation is y = -2/3x + 2 ( as 2 is the y-intercept).
In standard form this is :
3y = -2x + 6
2x + 3y = 6.

What’s the value of X in this triangle
Answer:
x = 85
Step-by-step explanation:
Step 1: Solve x
∠x = 180 - 27 - 68
∠x = 85
Therefore angle x equals 85
Answer:
85 degrees
Step-by-step explanation:
The sum of the angles of a triangle always add up to 180 degrees.
Here, we have two angles already given, so we can write:
27 + 68 + x = 180
95 + x = 180
Subtract 95 from both sides:
x = 180 - 95 = 85
The answer is thus 85 degrees.

The product of six and a number increased by six?
Answer: 6•(n+6)
Step-by-step explanation:
n is number
can be any letter
Answer:
6(n+6)
Step-by-step explanation:
the product means multiplication so you're going to need to multiply 6 by the number increased by 6. n represents the number, so n increased by 6 would be n+6. the parentheses represent the multiplication. put it together and you get the answer 6(n+6)
4(-8x+5) - (-33x-26)
Answer:
Step-by-step explanation:
Use distributive property a(b+c) = a*b +a*c
4(-8x + 5) - (-33x - 26) = 4*-8x + 4 *5 - 33x * (-1) - 26*(-1)
= -32x + 20 + 33x + 26
{add like terms}
= -32x + 33x + 20 +26
= 1x + 46

simplify- 13= 7x + 4 - 4x simplify- b - 6 + 6b = 27 simplify- 5(5x - 2) = 65 URGENT please answer i will give brainliest
Step-by-step explanation:
1: - 13= 7x + 4 - 4x
Isolate variables.
- 13= 7x + 4 - 4x
-13 = 3x + 4
-3x = 13+4
-3x = 17
x = -17/3
2: - b - 6 + 6b = 27
5b - 6 = 27
5b = 33
b = 33/5
3: - 5(5x - 2) = 65
-25x + 10 = 65
-25x = 55
x = -55/25
x = -11/5

A triangle has a base of (3x + 7) and a height of (5x - 1). A second
triangle is drawn with a base that is tripled and a height that is
doubled. Find the difference between the area of the original triangle
and the area of the new triangle.
Answer:
The difference between the area of the original triangle and the area of the new triangle is [tex]\Delta A_{\bigtriangleup} = \frac{5}{2}\cdot (3\cdot x +7)\cdot (5\cdot x -1)[/tex].
Step-by-step explanation:
The equation for the area of a triangle ([tex]A_{\bigtriangleup}[/tex]) is:
[tex]A_{\bigtriangleup} = \frac{1}{2}\cdot b \cdot h[/tex]
Where:
[tex]b[/tex] - Base, dimensionless.
[tex]h[/tex] - Height, dimensionless.
The expression for each triangle are described below:
First Triangle ([tex]b = 3\cdot x + 7[/tex], [tex]h = 5\cdot x - 1[/tex])
[tex]A_{\bigtriangleup,1} = \frac{1}{2}\cdot (3\cdot x+7)\cdot (5\cdot x -1)[/tex]
Second Triangle ([tex]b = 3\cdot (3\cdot x+7)[/tex], [tex]h = 2\cdot (5\cdot x -1)[/tex])
[tex]A_{\bigtriangleup,2} = 3\cdot (3\cdot x+7)\cdot (5\cdot x -1)[/tex]
The difference between the area of the original triangle and the area of the new triangle is:
[tex]\Delta A_{\bigtriangleup} = A_{\bigtriangleup,2}-A_{\bigtriangleup,1}[/tex]
[tex]\Delta A_{\bigtriangleup} = 3\cdot (3\cdot x+7)\cdot (5\cdot x-1)-\frac{1}{2} \cdot (3\cdot x+7)\cdot (5\cdot x-1)[/tex]
[tex]\Delta A_{\bigtriangleup} = \frac{5}{2}\cdot (3\cdot x +7)\cdot (5\cdot x -1)[/tex]
The difference between the area of the original triangle and the area of the new triangle is [tex]\Delta A_{\bigtriangleup} = \frac{5}{2}\cdot (3\cdot x +7)\cdot (5\cdot x -1)[/tex].

Sum of angle
measures: 360°
Answer:
In the given quadrilateral, two angles measure 60° and other two angles measure 120°.
Step-by-step explanation:
As we know sum of all interior angles of a polygon with 'n' sides is,
Sum of interior angles = (n - 2) × 180°
= (4 - 2) × 180° [for a polygon with n = 4]
= 360°
a + a + 2a + 2a = 360°
6a = 360°
x = 60°
Measure of angles = a° = 60°
And angles having measure = 2a° = 2(60)°
= 120°
Therefore, in the given quadrilateral, two angles measure 60° and other two angles measure 120°.

Find t12 for a geometric sequence where t1=2+2i and r=3
Answer:
[tex]T_{12} = 354294 + 354294i[/tex]
Step-by-step explanation:
Given
Geometric Sequence (GP)
[tex]T_1 = 2 + 2i[/tex]
[tex]r = 3[/tex]
Required
Determine T₁₂
The nth term of a GP is calculated as thus;
[tex]T_n = ar^{n-1}[/tex]
In this case;
[tex]n = 12[/tex]; [tex]r = 3[/tex] and [tex]a = T_1 = 2 + 2i[/tex]
Substitute these values in the above formula
[tex]T_{12} = (2 + 2i) * 3^{12-1}[/tex]
[tex]T_{12} = (2 + 2i) * 3^{11}[/tex]
[tex]T_{12} = (2 + 2i) * 177147[/tex]
Open the bracket
[tex]T_{12} = 177147 * 2 + 177147 * 2i[/tex]
[tex]T_{12} = 354294 + 354294i[/tex]
Hence, the 12th term of the sequence is [tex]T_{12} = 354294 + 354294i[/tex]

the ratios in an equivalent ratio table are 3:12, 4:16, and 5:20. if the first number of the ratio is 10, what is the second number? justify your reasoning.
Answer:
10:40
Step-by-step explanation:
3x4 = 12
4 x 4 = 16
5 x 4 = 20
so 10 x 4 = 40 (10:40)
Answer:
10:40
Step-by-step explanation:
Step 1: Reduce ratio to lowest value
3 : 12 = 1 : 4
*Divide by 3
Step 2: Solve ratio
Let 'x' represent the second number
1 : 4 = 10 : x
Multiple the left side by 10
10 : 40 = 10 : x
Therefore the second number in the ratio with 10 is 40
Find the measure of APBˆ. A. 130 B. 63 C. 50 D. 230
Answer:
65
Step-by-step explanation:
TAB is an isosceles triangle by the point to tangent theorem theorem.
BAT and BAT are congruent because of the isosceles triangle definition.
CAT and ABT are right angles by the tangent theorem.
Thus, CAB and CBA are both 90 - 65 = 25.
ACB is 130 because triangles' angles add up to 180.
APB is one half of ACB by the inscribed angles theorem.
The measure of the arc APB will be 230°. Then the correct option is D.
What is a circle?
It is the circle of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
We know that the tangents are equal.
Then triangle ΔATB is an isosceles triangle.
Then the angle ∠TAB and angle ∠TBA are congruent.
We know that the angle sum of a triangle is 180°.
∠TAB + ∠TBA + ∠ATB = 180°
65° + 65° + z = 180°
z = 50°
We know that the radius and tangent of circle make 90°.
And the angle sum of quadrilateral is 360°.
∠TAC + ∠TBC + ∠ATB + ∠ACB = 360°
90° + 90° + 50° + y = 180°
y = 130°
Then the measure of the arc APB will be
x = 360° – 130°
x = 230°
The measure of the arc APB will be 230°.
Then the correct option is D.
