2.) Five minus four times a variable equals negative seven
Answer:
[tex]5 - 4x = - 7[/tex]
Step-by-step explanation:
Let the missing variable be x then yiu will get the answer above
Answer:
3
Step-by-step explanation:
5 - 4x = -7
add 4x to each side of the equation:
5 = 4x - 7
add 7 to each side:
12 = 4x
divide both sides by 4:
x = 3
proof:
5 = 4(3) - 7
5 = 12 - 7
5 = 5
if the height of water in the tank is 10cm what is the volume of the water
Answer:
4500cm^3
Step-by-step explanation:
We use the normal formula for volume V= L•W•H just changing the H value from 20 to 10 because the water isn't at the full hight
10•30•15=4500

use the area of the rectangle to find the area of the triangle 2 ft 9 ft
Answer:
[tex]\Huge\boxed{B}[/tex]
Step-by-step explanation:
Hello There!
The area of a rectangle is equal to length times width
2*9=18 so the area of the rectangle is 18 square feet
If a triangle is formed in a rectangle then that triangle is 1 half of the area of the rectangle
18/2=9 so the area of the triangle is 9 square feet

Answer:
B and C are the correct options
The side length of the square with an area of 24 square units will be √24 units. Then the correct options are B and C.
What is the area of the square?Every one of the sides of a square is consistent. Let 'x' be the side length of the square. Then the region of the square is the square of the side length of the square.
Then the area of the square will be
Area of the square = x² square units
The expression is given below.
⇒ √24
If the area of the square is 24 square units. Then the side length is given as,
x · x = Area
x · x = 24
x² = 24
x = √24

Total amount = P (1 + i)t Alisha has a five–year car loan of $15,000 with an interest rate of 6 percent. If the interest is compounded annually, how much will she pay in total for her car?
Answer:
$20070
Step-by-step explanation:
Given data
Time= 5 years
Principal= $15,000
Rate= 6%
Total amount= P (1 + i)^t
substitute
Total amount= 15000(1 + 0.06)^5
Total amount= 15000 (1.06)^5
Total amount= 15000*1.338
Total amount= $20070
Hence the total amount will be $20070

A colony of 36,000 bacteria grows continuously at a rate of 12%.
9514 1404 393
Answer:
b(t) = 36000·e^(0.12t)
Step-by-step explanation:
Continuous growth at a rate of r per time period is modeled by the exponential multiplier e^(rt), where t is the number of time periods. This value multiplies the initial amount (at t=0). In this case, the model would be ...
b(t) = 36000·e^(0.12t)
where b(t) is the number of bacteria in the colony after t time periods.

B. –1
C. 1
D. [tex]-\frac{3}{8}[/tex]
Answer:
B. -1
Step-by-step explanation:
-1
According to the slope formula:
Slope = (y2 - y1)/(x2 - x1)
y2 = 6.1
y1 = 3.1
x2 = -5.5
x1 = -2.5
Therefore:
6.1-3.1/-5.5--2.5
Since negative negative is positive you are left with:
3/-3
Therefore the answer is -1.

The speed, v, of a wave is inversely proportional to the square root of the
depth, d, of the water. When v= 30 then d = 400.
Find y when d=25.
Answer:
v = 120
Step-by-step explanation:
If v is inversely proportional to square root of d, then we can write
[tex]v \sqrt{d}[/tex] = k
If v = 30 and d = 400, then
30([tex]\sqrt{400}[/tex]) = k
k = 30(20) = 600
Now [tex]v \sqrt{d}[/tex] = 600
If d = 25, then v[tex]\sqrt{25}[/tex] = 600
5v = 600
v = 120
Keegan deposited $550 in savings account that pays 6.5% annual interest compounded quarterly write the compound interest formula to represent keegan's investment after 5 years how much money would Keegan have in the account after 5 years
Answer:
A = $759.23 after 5 years
Step-by-step explanation:
The compound interest formula applicable here is
A = P(1 + r/n)^(nt), where n is the number of compounding periods per year.
Here P = $550, r = 0.065, n = 4 and t = 5.
We get A = $550(1 + 0.065/4)^(4*5), or
A = $550(1 + 0.01625)^20, or:
A = $759.23

A train travels 20 miles in 15 minutes. how far will it travel in an hour and a half
Answer:
120
Step-by-step explanation:
One hour is 90 minutes 90/15=6 then you take 20X6=120miles
Answer:
It will travel 120 miles
Step-by-step explanation:
First, convert the hour and half to minutes: 90 minutes.
Then divide 90 with 15: 6
Then since there are 6 sections of 15 minutes, you would multiply 20 times 6 which is 120.

Han wrote a proof that triangle BCD is congruent to triangle DAB. Han's proof is incomplete. Which step is missing some information? DC∥AB
Step 1: Line AB is parallel to line DC and cut by transversal DB. So angles CDB and ABD are alternate interior angles and must be congruent.
Step 2: Side DB is congruent to side BD because they're the same segment.
Step 3: Angle A is congruent to angle C because they're both right angles.
Step 4: By the Angle-Side-Angle Triangle Congruence Theorem, triangle BCD is congruent to triangle DAB .
and WHY?
Answer:
The answer is below
Step-by-step explanation:
From the image, we can see that DC is parallel to AB.
Step 1:
Alternate interior angles are angles formed at the inner corners of intersection on opposite sides of transversal when two parallel lines are intersected by a transversal.
Since Line AB is parallel to line DC and cut by transversal DB. So angles CDB and ABD are alternate interior angles and must be congruent.
Step 2:
DB ≅ BD (reflexive property of congruence)
Step 3:
∠A = ∠C = 90° (right angles, given). But to prove that both triangles are congruent, the correct step 3 is:
Since, ∠A = ∠C = 90° and angles CDB and ABD are congruent. This means that the third angles in the both triangles are also congruent. Hence, angle ADB and CBD are must be congruent.
Step 4:
BD = DB, angles CDB and ABD are congruent, angle ADB and CBD are congruent.
Therefore, By the Angle-Side-Angle Triangle Congruence Theorem, triangle BCD is congruent to triangle DAB .

The area of a circle is πr².
We have,
The circumference of a circle can be found using the formula:
C = 2πr
where r is the circle's radius and π (pi) is a mathematical constant approximately equal to 3.14159.
Substituting r = 9 m into the formula, we get:
C = 2π × 9
C = 18π m
Therefore,
The circumference of the circle is 18π meters.
