Answer:
Step-by-step explanation:
L=3(5280)/(2(380+250))
L=15840/1260
L=12.57
So to walk three miles one must walk around the garden 12.57 times.
What are the angle measures?
a. Equation:
3x + 21 = 6x - 60 {measure of corresponding angles is the same}
3x - 6x = -60 - 21
- 3x = - 81
b. Value of x:
x = 27
c. Ange measures:
3x + 21 = 3×27 + 21 = 81 + 21 = 102°
or:
6x - 60 = 6×27 - 60 = 162 - 60 = 102°

What is the exponential function (0,25) (1,50) (2,100) (3,200) (4,400)
Answer:
Step-by-step explanation:
If it is exponential dividing any term by the preceding term will be a constant, the common ratio or rate. 50/25=100/50...=2 The initial value, a, (at x=0) is 25 so the general form is
y=ar^x we have a=25 and r=2 so
y=25(2^x)
what is The graph of y=-3x+4
Answer:
Use the slope-intercept form to find the slope and y-intercept.
Slope: −3 . y-intercept: (0,4)
Any line can be graphed using two points. Select two x values, and plug them into the equation to find the corresponding y values.

One interior angle of a parallelogram is 65 degrees . If the remaining angles have measures of a,b and c, what is the value of a+b+c?
Answer:
65 + 65 = 130
360 - 130 = 230 degrees
Which of the expressions have like terms? Select all that apply
A. -6m + 4m
B. t + 6.75t
C. 10m + mn
D. 6 - 6p
E. 9xy - 4xy
F. 2y + 5x
Answer:
A, B, and E
Step-by-step explanation:
When talking about like terms you need to look at the variable. You have to look at which has the same variables and then you can determine which are like terms.
For A --> -6m + 4m both have m as a variable. They can be combined. Which is why they are like terms. Do the same for the rest.
What would NOT be like terms?
C-- 10m + mn
This is wrong because of the variable. the variable for 10m is m. When there is only a variable you can pretend there is a 1 (For example, m can be 1m but we ignore that). mn is a variable as a whole. So if we added one to the front, the variables of 10m and 1mn would not match! It does not matter if they both have an m, because the value would be different either way.
Hope this helps!!

Answer:
Step 2 is where the error lies.
The solution is x > 6
Step-by-step explanation:
The rules for solving inequalities are substantially similar to the rules for solving equations. If you perform the same operation on both sides of the comparison, the value of the variable does not change. (The exception is when that operation is an "order-reversing" operation. See comment below.)
Kahal's steps would be expected to be the same ones you would use:
Step 1: 4x -4 > 20 . . . given
Step 2: 4x > 24 . . . add 4 to both sides
Step 3: x > 6 . . . . . divide by 4
We note that our Step 2 is different from Kahal's Step 2. In Step 2 is where his mistake was made. He added 4 to one side and subtracted 4 from the other side.
__
Exception (order-reversing operations)
The operation you will usually run across in high-school algebra that will reverse ordering is multiplication (or division) by a negative number. Consider, for example, ...
1 < 2
-1 > -2 . . . . . both sides of the inequality multiplied (or divided) by -1
Notice that the order has been reversed: the larger magnitude number is now "less than".

here's a formula:
a=2b-c
what is the value of a if b=11 and c=3?
Answer:
a = 19
Step-by-step explanation:
a=2b-c
a= 2(11) - 3
a = 22 - 3
a = 19
Answer:
a = 19
Step-by-step explanation:
2 x 11 = 22 - 3 = 19
So a = 19
Convert into kilometer 213 km 42 m
Answer:
213.042 km
Step-by-step explanation:
We need to convert 213 km 42 m to km.
We know that,
1 km = 1000 m
or
1 m = (1/1000)km
So,
42 m = (42/1000) km
It means,
[tex]213\ km\ 42\ m=213\ km+\dfrac{42}{1000}\ km\\\\=213.042\ km[/tex]
So, the required answer is 213.042 km.
using the triangle below find the measure of angle B round your answer to the nearest whole number
Answer:
angle v = 46 degrees
Step-by-step explanation:
tan-1 = [tex]\frac{opposite}{adjacent}[/tex]
tan-1 V = [tex]\frac{21}{20}[/tex]
[tex]\frac{21}{20}[/tex] = 1.05
tan-1 V = 1.05
V = 46.397
round to the nearest whole number:
46.397 = 46

Work out the area of ABCDE.
(5 marks)
cm2
Answer:
area = 44 cm²
Step-by-step explanation:
rectangle area = bh = 8 x 4 = 32 cm²
triangle height² = 5² - 4³ = 25 - 16 = 9
triangle height = 3
triangle area = 1/2bh = 1/2(8)(3) = 12 cm²
32 cm² + 12 cm² = 44 cm²
area = 44 cm²
Answer as quickly as you possibly can
Answer:
m = 3/2
Step-by-step explanation:
You want to find the slope, or the change in y coordinates over change in x-coordinates.
The first given point is E(-2, -4)
The second point is F(2, 2)
Coordinates are given in (x, y), so following the equation and computing the x and y coordinates of E - F for both the numerator and denominator:
[tex]\frac{y_2 - y_1}{x_2-x_1} = \frac{-4 -2}{-2 -2} = \frac{-6}{-4} = \frac{3}{2}[/tex]
You could also have went the other way and calculated F - E for the numerator and denominator and get the same answer.
Finally, to check you can also look at the graph through the rise over run (rise/run) method and see that from E, you go up 3 (rise) and to the right 2 (run) to get to the next point on the line.

Fred drew 2/3 on a number line. Sara broke her number line into 6 equal pieces but found the same fraction on the number line as Fred. What fraction did Sara make?
Answer:
4 / 6
Step-by-step explanation:
Fred fraction = 2/3
Sarah formed a fraction by dividing her number line into 6 equal pieces. This is given as;
x / 6
Since her fraction is equal to that of fred, we have;
x / 6 = 2 / 3
x = 6 * 2 / 3 = 4
Sarah Fraction = 4 / 6
In the given diagram(see image) , TAX and TBY are tangents to the circle and C is a point on the major arc.
Question :
If <CAX = 65° , <CBY = 76° , Calculate <ATB.
Answer:
∠ATB = 102°
Step-by-step explanation:
Since ∠CBY is less than 90°, CB is not a diameter.
I did this in my head so I drew a sketch to show that around about way I did it. sketch attached:
I drew a third line from X to Y that is tangent to the circle at C.
Because each pair of tangent lines to a common point are equal, we have made three isosceles triangles.
Now we know 2 of the three angles to ΔXYT, 180 - 50 - 28 = 102° for ∠ATB
Answer:
102°Step-by-step explanation:
Given
∠CAX = 65° , ∠CBY = 76°To find
∠ATBSolution
Refer to attached picture
∠CAX= ∠CBA as same arc intercepted ∠CBY = ∠CAB as same arc interceptedTAX is a straight angle and:
∠TAB = 180° - (∠CAX + ∠CAB) = 180° - (65° + 76°) = 39°∠TBA = ∠TAB as two tangents intersect at same distance, their opposite angles are therefore same. ΔATB is an isosceles triangle.
∠ATB = 180° - 2*39° = 102°What is the square root of √25
