how to find a in this ?
Answer:
see explanation
Step-by-step explanation:
(a)
The triangle has 2 congruent sides and is therefore isosceles.
(b)
The base angles of an isosceles triangle are congruent, thus
a = [tex]\frac{180-52}{2}[/tex] = [tex]\frac{128}{2}[/tex] = 64
(c)
a = b = 64 ( alternate angles )
Solve each inequality.
1. 2(k + 4) - 3k ≤ 14
2. 3(4c - 5) - 2c > 0
3. -x + 2 < 3x - 6
4. 3v - 12 > 5v + 10
3. -x + 2 < 3x - 6
=3x +x < 2 + 6
=4x < 8
=x > 8/4
=x > 2
4. 3v - 12 > 5v + 10
= 5v-3v > 10+12
=2v > 22
= v < 22/2
=v < 11

y=-2 4x-3y=18 equations using substitution
Answer:
X = 3
Y = -2
Step-by-step explanation:
If y = -2, you can plug in -2 for y in the equation 4x - 3y. This means that this equation will become 4x -3(-2) = 4x+6=18. Solve for x from this, and you will get 3.
Answer:
x=3/y=-2

Step-by-step explanation:
Write the equation of the line that passes through the given points. (8,0) and (0,4)
Answer:
[tex]y = - \frac{1}{2} x + 4[/tex]
Step-by-step explanation:
The equation of a line can be written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
This is also known as the slope-intercept form.
[tex]\boxed{gradient = \frac{y1 - y2}{x1 - x2} }, \\ where \: (x1, y1) \: is \: the \: 1st \: coordinate \: and \: (x2, y2) \: is \: the \: 2nd \: coordinate.[/tex]
Find the value of m using the gradient formula above:
[tex]m = \frac{4 - 0}{0 - 8} \\ m = \frac{4}{ - 8} \\ m = - \frac{1}{2} [/tex]
Substitute m= -½ into the equation:
y= -½x +c
To find the value of c, substitute a pair of coordinates:
When x= 0, y=4,
[tex]4 = - \frac{1}{2} (0) + c \\ 4 = c \\ c = 4[/tex]
Thus, the equation of the line is y= -½x +4.

Answer: Four more than zero, four greater then zero, positive four.
Step-by-step explanation: hope this helps
Answer:
Four more than zeroFour greater than zeroPositive fourStep-by-step explanation:
The original statement is "four above zero". Four above zero is 4.
Negative four, would be -4. That is the opposite of the original answer. Therefore, they're not equal.Four more than zero is 0 + 4. 0 + 4 is 4, which is the answer to the original statement. Therefore, they're equal.Four greater than zero is represented like this: 0 + 4. 0 + 4 = 4, so they are equal.The opposite of positive four is negative four, so it is not correct.Four less than zero is this: 0 - 4. 0 - 4 is equal to -4, so they are not equal.Positive four is pretty self-explanatory. It's 4. So, that is correct and equal to the original statement.I hope this helps!

Company DIMOND just paid annual dividend of $5 today. The dividend is expected to grow at 3% for the next 5 years, then it will grow at 5% in perpetuity. If stocks of similar company earn 9% annual return, what is the price of a share of Company DIMOND stock?
Answer:
$120.05
Step-by-step explanation:
Div₀ = $5
Div₁ = $5.15
Div₂ = $5.3045
Div₃ = $5.463635
Div₄ = $5.62754405
Div₅ = $5.796370372
Div₆ = $6.08618889
first we must determine the terminal value on year 5:
terminal value = $6.08618889 / (9% - 5%) = $152.1547223
now we determine the present values of our future dividends + terminal value = $5.15/1.09 + $5.3045/1.09² + $5.463635/1.09³ + $5.62754405/1.09⁴ + $5.796370372/1.09⁵ + $152.1547223/1.09⁵ = $4.724 + $4.464 + $4.219 + $3.987 + $3.767 + $98.890 = $120.05
2/9 of the members are boys in a community service club. if there are 95 more girls than boys, how many girls are there in club?
Answer:
There are 171 members in the club
Number of boys = 38
Number of girls = 133
Step-by-step explanation:
Let
x = total members of the club
Boys = 2/9x
if there are 95 more girls than boys
Girls = 2/9x + 95
how many girls are there in club?
Total members in the club = boys + girls
x = 2/9x + 2/9x + 95
x = 2+2/9x + 95
x = 4/9x + 95
x - 4/9x = 95
9x-4x/9 = 95
5/9x = 95
Divide both sides by 5/9
x = 95 ÷ 5/9
= 95 × 9/5
= 855/5
= 171
boys = 2/9x
= 2/9 * 171
= 342 / 9
= 38
Girls = 2/9x + 95
= 38 + 95
= 133
Total = 38 + 133
= 171
There are 171 members in the club
Number of boys = 38
Number of girls = 133
Evaluate: 30 - 12÷3×2 =
Answer:
22
Step-by-step explanation:
We can use the order of operations (PEMDAS), to solve this equation.
We must first multiply and divide, and order. This means we divide 12 by 3 and get 4, then multiply that by 2 and get 8. (30-12÷3×2,30-4×2,30-8). Now we just subtract 8 from 30 and get 22 as our answer.
When a dilation occurs the original figure is
Answer:
A dilation stretches or shrinks the original figure. A description of a dilation includes the scale factor (or ratio) and the center of the dilation. The center of dilation is a fixed point in the plane. If the scale factor is greater than 1, the image is an enlargement (a stretch).

Jerry has just purchased his first home for $190,000. He put down a 20 percent down payment of $38,000 and took out a 5 percent mortgage for the rest. His mortgage payment is $700 per month. How much of his first monthly mortgage payment is amortization?
Answer:
$66.67
Step-by-step explanation:
The calculation of first monthly mortgage payment is amortization is given below:-
Amount borrowed = Purchase first home cost - Down payment
= $190,000 - $38,000
= $152,000
Annual interest = ($152,000 × 5%) ÷ 12
= $7,600 ÷ 12
= $633.33 per month
Now,
First monthly payment = Mortgage payment - Annual interest
= $700 - $633.33
= $66.67
Hence, we simply applied the above formula.

Because if you multiply 82 x 2 it would equal 164 but you can also divide each number by 82 to get your answer
Jacob ordered pizza from his favorite pizzeria. The pizzeria delivers pizzas for $10 each plus a delivery charge of $2.99. Jacob paid a total of $32.99. Write an equation that models this situation. Let p = the number of pizzas delivered. Equation:
Answer:
$10p + $ 2.99 = $32.99
Step-by-step explanation:
I got this because he got multiple pizzas that are each $10, but we don't know how many there are, so I put $10p together.
He also pays $2.99 as a delivery charge.
And I ended it with the equation equaling $32.99 because that is the total he paid.
He was given 35 euros for $45.00.what was the approximate exchange rate in euros per dollars?
Answer:
0.78 euros per dollar
Step-by-step explanation:
If 35 euros=$45.00, then every dollar that he has is equivalent to (35/45) euros=35/45=0.78 euros per dollar

Two planes leave San Antonio at the same time.
The northbound planc travels 70 mih faster than
the southbound plane. The planes are 1940 mi
upart in 2 h. How fast is the southbound plane
flying?
Answer:
Speed of the southbound plane = 450 mph
Step-by-step explanation:
Let the speed of the northbound plane = x miles per hour
And the speed of the southbound plane = y mph
Since, northbound plane travels 70 mph faster than the southbound plane,
x = y + 70 -----(1)
The planes are 1940 miles apart in 2 hours.
From the formula,
Distance traveled = Speed × time
Distance traveled by northbound plane in 2 hours = 2x miles
Distance traveled by the southbound plane in 2 hours = 2y miles
2x + 2y = 1940
x + y = 970 -----(2)
By substituting the value of x in equation (2) from equation (1)
y + 70 + y = 970
2y = 970 - 70
y = 450 mph
from equation (2)
x + 450 = 970
x = 520 mph
