Answer:
A=147 units²
Step-by-step explanation:
Area for rectangle is A=bh (base x height)
Knowing that, we can substitute what we know. So we know that b=3h (3 times the length of the other side), however we also know that b-h=14 (difference between the two is 14).
Let's solve so that we get b by itself for the second equation
b-h=14
b=h+14
Now we have b=3h and b=h+14. We can have them equal each other since they both equal b.
3h=h+14
2h=14
h=7
Now let's go back and plug into b if we know h=7.
b=3h
b=3(7)
b=21
Now we know h=7 and b=21, so let's plug that into the area for a rectangle which is A=bh
A=bh
A=(21)(7)
A=147 units²

Answer:
D. {-2,12}
Step-by-step explanation:
you have to the equation with the answer being both negative and positive because it is absolute value...
c-5= 7 c-5= -7
add 5 to both sides on both equations
c-5= 7 and c-5= -7

A diver descends at a rate of 12 feet per minute for 11 minutes. Write and solve an expression to show what the divers ending depth would be.
Answer:
132ft
Step-by-step explanation:
Given data
We are told that a diver descends at 12 ft per minutes
The time taken is 11 minutes
From
Speed= distance/time
distance= speed*time
Substitute
distance= 12*11
distance=132ft
Hence the ending distance is 132ft
Can someone please do 4 x 5/6 on a number line
(x+6) (x-2) multiply out
Answer:
x² + 4x - 12
Step-by-step explanation:
(x + 6)(x - 2)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x - 2) + 6(x - 2) ← distribute parenthesis
= x² - 2x + 6x - 12 ← collect like terms
= x² + 4x - 12

Answer:
Equation for Leandro: y=0.3x+8.95
Equation for Tina: y=0.25x+8.95
The slope is not the same, because in this equation, the coefficient of the x (the number right before the "x") isn't the same. 0.3 does not equal 0.25.
However, the y-intercept is the same, as for both equations it is 8.95.
From this, we can see that there is only one solution, at the y-intercept of (0,8.95).

Answer:
19/20
Step-by-step explanation:
Write an equation in slope-intercept form that passes through (5, -8) and runs perpendicular to y = 5/2x + 4
y= (-2/5)x-6
Step-by-step explanation:
the slope of the line perpendicular the the given line is found by the formula m1.m2= -1 hence m2= -2/5
using the slope-intercept form
y+8= -2/5(x-5) y= (-2/5)x-6

What is the simple interest on $40,000 for 10 years at 12%?
A.)$50,000
B.)$48,000
C.)$64,000
D.)$55,000
Answer:
To find the simple interest, we multiply 40000 × 0.12 × 10 to get that:
The interest is: $48000.00
Usually now, the interest is added onto the principal to figure some new amount after 10 year(s),
or 40000.00 + 48000.00 = 88000.00. For example:
If you borrowed the $40000.00, you would now owe $88000.00
If you loaned someone $40000.00, you would now be due $88000.00

what is this(9 + 4) × (8 -7)
Answer:
13
Step-by-step explanation:
To solve this you have to add 9 and 4 first so you get 13. Next, you have to subtract 8 from 7 so you get 1. Now all you have to do is multiply 13 and 1 so you get 13 as your answer.
9 + 4 = 13
8 - 7 = 1
13 × 1 = 13
I hope this helps you :D
Answer:
Its 13
Step-by-step explanation:
Pretty much its 9 + 4 (13) x 1 which equals 13.
Toko sepatu memberi diskon 30% untuk semua barang.Jika tasya membeli sepasang sepatu dan ia membayar Rp 336.000,00 setelah mendapat diskon,harga sepasang sepatu tersebut sebelum diskon adalah
Answer:
IDR 480,000
Step-by-step explanation:
Persentase diskon = Harga lama - Harga baru / Harga lama
Harga lama = Harga sebelum diskon = x
Harga Baru = IDR 336000
Persentase diskon = 30%
Karenanya:
30% = x - 336000 / x
30/100 = x - 336000 / x
0.3 = x - 336000 / x
Cross Multiply
0.3 × x = x - 336000
0.3x = x - 336000
x - 0.3x = 336000
0.7x = 336000
x = 336000 / 0.7
x = IDR 480,000

Write an equation of the circle with center (-2,5) radius 9
Answer:
(x+2)²+(y-5)² = 81
Step-by-step explanation:
The formula for calculating equation of a line is expressed as
(x-a)²+(y-b)² = r²
(a,b) are the points
r is the radius
Given
Point = (-2,5)
Radius = 9
Substitute
(x-(-2)²+(y-5)² = 9²
(x+2)²+(y-5)² = 81
Hence the required equation is (x+2)²+(y-5)² = 81

A circular "No Parking" road sign has a diameter of 26 inches.
Which measurement is closest to the area of the sign in square inches?
81.64 in.²
163.28 in.²
530.66 in.²
2,122.64 in.²
Answer:
i think 81.64
Step-by-step explanation:
The area of the road sign in the circular shape of diameter 26 inches is closest to 530.66 in².
A road sign "No Parking" is given in a circular shape of diameter 26 inches. we need to find the area of the sign.
What is the area of a circle?The area of the circle is pie times the square of the radius of a given circle.
The area of the circle = [tex]\rm \pi r^{2}[/tex]
The diameter of the circle is 26 in so, the radius will be half of the diameter which will be 13 in.
Now, the area of the circle = [tex]\rm \pi r^{2}[/tex]
the area of the circle = 3.14 × 13 × 13
= 530.66 in²
Hence, the area of a circle of diameter 26 inches is equal to 530.66 in².

What is a law of sine?Law of sines is a formula relating the length of the sides of a triangle to the angles of the triangle.
In Triangle JKL
< K J L = 58 degrees
< J L K = 38 degrees.
and, J K = 2.3, J L = k.
As, <KJL + <JKL + <LKJ = 180
58+ 23 + <LKJ = 180
<LKJ = 99 degree.
Using Law of sines
k/ sin K = j/ sin J
k/ sin 99 = 2.3/ sin 58
