On a 40‐point test, Steve received an 80%. How many points did he receive on the test?

Answer: 36

Step-by-step explanation:

The top and bottom of the parallelogram both have lengths of 8.

To determine the length of the parallel diagonal sides, form a right triangle using the left side of the parallelogram as its hypotenuse (in red in my diagram below).

The right triangle has legs of length 6 and 8, so the length of the hypotenuse (c) is:

6^2 + 8^2 = c^2

36 + 64 = c^2

100 = c^2

c = 10

Thus the two diagonal sides of the parallelogram must both have a length of 10, so the perimeter of the parallelogram is 8 + 10 + 8 + 10 = 36.

Answer:

[tex]\huge\boxed{3\frac{1}{2}}[/tex]

[tex]\frac{7}{2}[/tex] as a mixed number:

Divide 2 from 7 and find the remainder:

7 ÷ 2 = 3 R 1.

An improper fraction in mixed form has the quotient as the coefficient, and the remainder over the fraction. Therefore:

[tex]\frac{7}{2} = 3\frac{1}{2}[/tex]

Answer:

[tex]3\frac{1}{2}[/tex]

Step-by-step explanation:

Step 1: Define mixed fraction

A mixed fraction is a number with a whole number and a fraction together

Step 2: Find mixed fraction

Ask how many time can 2 completely fit into 7 without leaving anything left over, 2 fits in 7 3 times because 2 x 3 = 6 and 7 - 6 is 1.  We put 3 in front of the fraction and we keep the 1 left over in the numerator of the fraction with 2 as the denominator to get [tex]3\frac{1}{2}[/tex]

The equations

[tex]x = r*\cos(\theta)\\\\y = r*\sin(\theta)[/tex]

are useful to convert from polar to Cartesian

So,

[tex]x = r*\cos(\theta)\\\\x = r*\cos\left(\frac{\pi}{3}\right)\\\\x = r*\frac{1}{2} \ \text{ use unit circle} \\\\x = \frac{1}{2}r[/tex]

Answer:

The independent variable = The volume of water in the aquarium

The dependent variable = The time it will take to drain the aquarium

Step-by-step explanation:

The independent variable, as indicated in the name is the variable that is not influenced by other variables but can predetermine its own self and it is not altered by the other variables being analysed

Therefore, the independent variable is the water in the 200 gallon aquarium

The dependent variable, is the tested or measured variable and is dependent on the independent variable, which is the time it takes to drain the 200 gallon aquarium.

If [tex]x=0[/tex], then [tex]y=a\cdot0^2+b\cdot0+c=5[/tex], so [tex]c=5[/tex].

If [tex]x=1[/tex], then [tex]y=a\cdot1^2+b\cdot1+c=2[/tex], so [tex]a+b+5=2[/tex] or [tex]a+b=-3[/tex].

If [tex]x=2[/tex], then [tex]y=a\cdot2^2+b\cdot2+c=1[/tex], so [tex]4a+2b+5=1[/tex] or [tex]2a+b=-2[/tex].

We have

[tex]a+b=-3\implies -a-b=3[/tex]

[tex](2a+b)+(-a-b)=-2+3[/tex]

[tex]\implies a=1\implies b=-4[/tex]

So we end up with

Answer:

$ 79600

Step-by-step explanation:

interest=prt   (p is the amount borrowed, r is the rate, t is the time)

p=60000 , r=8%=0.08  , t=4 years

interest=60000*0.08*4

A=19600

the amount paid at the end of 4 years: 60000+19600=$79600

8x+2=90

8x=88

x=11

Let me know if this helps :)

Step-by-step explanation:

Hey, there!!

Let's simply work with it,

MA is perpendicular to AT.

To find: angle HAT.

Now,

angle HAT + (2x + 2)° + (3x + 5)° = 90° { As MA perpendicular to AT. }

Now,

Replace angle HAT by (3x - 5)°.

(3x-5)° + (2x+2)° + (3x+5)° = 90°

Open brackets,

3x - 5° + 2x + 2° + 3x + 5° = 90°

Add like terms.

8x + 2°= 90°

8x = 90°-2°

[tex]x = \frac{88°}{8} [/tex]

x= 11°.

Now, finding the value of angle HAT.

(3x-5)° = 3×11°-5°

Therefore, angle HAT is 28°.

Answer:

$6.36

Step-by-step explanation:

this is a system of equations problem. There are two main methods for this type of problem: elimination and substitution(I used both here). A-croissants, B-coffee.

The cost of an order of 1 croissant is $2.3 and 1 cup of coffee is $4.05.

We need to form the system of equations for the given statement.

In mathematics, a set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.

Let the cost of croissants be x and the cost of cups of coffee be y.

6 croissants and 3 cups of coffee costs $25.95

6x+3y=25.95-----(1)

1 croissant and 6 cups of coffee cost $26.70

x+6y=26.70-----(2)

(6x+3y)6=25.95×6

⇒36x+18y=155.7-----(3)

(x+6y)3=26.70×3

⇒3x+18y=80.1-----(4)

Subtract (4) from (3).

That is, 36x+18y-(3x+18y)=155.7-80.1

⇒33x=75.6

⇒x=2.3

Substitute x=2.3 in equation (1).

That is, 6(2.3)+3y=25.95

⇒3y=12.15

⇒y=4.05

Therefore, the cost of an order of 1 croissant is $2.3 and 1 cup of coffee is $4.05.

Answer: 0.786

Step-by-step explanation:

Here i would assume that:

Sector R and Sector Q do not have any sections in common.

Then, the probability that the spinner does not land on Q or R, is equal to the probability where the spinner does not land in a specified section of:

38° + 39° = 77°.

Now, the total section off the spinner is 360°.

If we remove those 77°, we have a section of:

360° - 77° = 283°

So we have 283° where the spinner CAN land on.

Then the probability that the spinner does NOT land on R or Q is equal to the quotient between the section of the spinner that is not R or Q, and the total section of the spinner"

P = 283/360 = 0.786

So the probability is 0.786

Answer:

Angle DAB is 29°.

Step-by-step explanation:

The lines in the two angles show that they are equal.

So angle DAB is equal to angle CAD.

m∠DAB is 29°

Given:

m∠CAD = 29°

From the image given showing ΔABC, the two angles, ∠CAD and ∠DAB are congruent to each other. This is indicated in the diagram with each single stroke on each angle.

Congruent angles are equal to each other.

∠CAD and ∠DAB are congruent angles.

Thus,

m∠CAD = m∠DAB = 29°

Therefore, m∠DAB is 29°

Quotient.

Step-by-step explanation:

You get a quotient by dividing something. It is the end result, the solution.

Answer: quotient

Step-by-step explanation: The answer to a division

problem is called the quotient.

So here we say the quotient of 18/2 is 9.

Step-by-step explanation:

[tex]density = \frac{mass}{volume} \\ volume = \frac{mass}{density} \\ changing \: 1.8 {gcm}^{ - 3} to \: {kgm}^{ - 3} \\ multiply \: by \: 1000 \\ = 1800 {kgm}^{ - 3} \\ volume = \frac{3.1}{1800} \\ = 0.00172 {m}^{ 3} [/tex]

The volume of 3.1 kg of concentrated sulfuric acid is 1722.22 [tex]cm^{3}[/tex].

Here's the solution:

The density of concentrated sulfuric acid is 1.8 g/[tex]cm^{3}[/tex]. This means that 1.8 grams of concentrated sulfuric acid will occupy 1 cubic centimeter of space.

If we have 3.1 kg of concentrated sulfuric acid, then we have 3100 grams of concentrated sulfuric acid.

The volume of this amount of concentrated sulfuric acid will be:

volume = mass / density

volume = 3100 g / 1.8 g/[tex]cm^{3}[/tex]

volume = 1722.22 [tex]cm^{3}[/tex]

Therefore, the volume of 3.1 kg of concentrated sulfuric acid is 1722.2[tex]cm^{3}[/tex]

Verifying each option stated :

Total value of stamp:

Each row add up to 35. Example (18 + 17) = 35

(20 + 15) = 35
