Plz i need help and asap plus work pls and no files

**Answer:**

25%

**Step-by-step explanation:**

so out of 32 marbles, 8 of them are red. This means the rest are blue which is 24 blue. To make a percentage, all you do is make a fraction. out of 32, 8 were red so 8/32. Fractions are basically division so 8/32 is 0.25. This means 25%.

-16(c-4)-12c+80 ( simplify each expression

**Answer:**

-28c+144

**Step-by-step explanation:**

if you simplify -16(c-4)-12c+80

it equals -28c+144

**Explanations: **

Distribute

-16**(c-4)**-12c + 80 ---> -16c + **64** - 12c +80

Add the numbers

-16c+**64**-12c+**80 --->** -16c+**144**-12c

**Answer:**

5

**Step-by-step explanation:**

to vick = W1 = 300 + 20 x ( 1 )

to anya = W2 = 250 + 30 x ( 2) Both 1 and 2 ( simulataneous )

When W1 = W2

300 + 20 x = 250 + 30 x

10 x = 5

Some students were asked to pick their favourite Action Hero.

3/5 chose Batman, 20% chose Hulk and the rest chose Iron Man.

.

Write the ratio of Batman: Hulk: Iron Man in Simplest form.

Select one:

a. 6:2:2

b. 60: 20:20

c. 3:1:1

**Answer:**

a

**Step-by-step explanation:**

First convert 3/5 to a percentage.

3/5 is 60% and 20% of the students chose Hulk. That leaves 20% who chose Iron Man. The simplest form of 60:20:20 is 6:2:2.

When instructed to find the length of HJ in right

triangle HJG, Alex wrote the equation

HJ

HJ

sin 28° = while Marlene wrote cos 62°

20

20

Are both students' equations correct? Explain

why.

H

+

20

28

O

G

See attachement for the diagram of the triangle

Answer/Step-by-step explanation:

To find the length of HJ, we can use different equations as follows:

✔️Recall: SOHCAHTOA

Let's take <G as the reference angle = 28°

Opposite side to reference angle = HJ

Hypotenuse = 20

Apply SOH.

Thus:

Sin 28° = opp/hyp

Sin 28° = HJ/20 (Alex's equation is correct).

Solving further, we would have:

HJ = Sin 28 * 20 ≈ 9.4

✔️Another way is by using <H as the reference angle.

m<H = 180° - (90° + 28°) (sum of triangle)

m<H = 62°

Adjacent side to reference angle (<H) = HJ

Hypotenuse = 20

Apply CAH:

Cos 62° = Adj/Hyp

Cos 62° = HJ/20 (Marlene's equation is correct)

Solving further, we would have,

HJ = Cos 62° * 20 ≈ 9.4

As you can see, the equation of both students are correct. Both would arrive at the same answer using any of the two equations.

**Answer:**

55 degrees

**Step-by-step explanation:**

Angle ACE and BDE are congruent so segments AC and BD are parallel. That makes angles CAE and DBE congruent.

6x - 15 = 5x - 1

x - 15 = -1

x = 14

So, the measure of angle BDE = 4x = 56 degrees. The measure of angle DBE = 5x - 1 = 69 degrees.

The total of all angles in triangle BDE is 180 degrees, so the measure of angle E = 180 - 56 - 69 = 55

A mattress store is having a sale all mattresses are 30% of. Nate wants to know the sale price of a mattress that is regularly $1,000

**Answer: $700**

**Step-by-step explanation:**

The store is selling at 30% off.

If a mattress is $1,000, first find out what 30% of $1,000 is:

= 1,000 * 30%

= $300

The store is selling 30% off, this means that they are reducing the price by 30%:

= 1,000 - 300

**= $700**

On Monday, a dental hygienist cleans teeth of 5 patients by the time she takes her lunch break at noon. On average, she is able to clean the teeth of 9 patients in 4 hours

Write a function to represent the number of patients she sees, y, and the number of hours, 2. the hygienist works after lunch on Monday.

Enter your answer in the box

PLEASE HELP!

y= 9/4x + 5

y = 9/4(2) + 5

y = 9.5

y= between 9-10 patients, round down to 9

y = 9/4(2) + 5

y = 9.5

y= between 9-10 patients, round down to 9

The **function** that represents the number of patients she sees is; y = 9/4x + 5 and number of patients after 2 hours is 9 patients

We are given;

Number of patients the dental hygeinist cleans before lunch = 5

**Average number **that she cleans after lunch = 9 patients in 4 hours

Thus, number of patients per hour is 9/4

The** formula** for **slope intercept form** is;

y = mx + c

Thus, **equation** to represent the situation in the question is;

y = 9/4x + 5

At 2 hours after lunch, number of patients is;

y = 9/4(2) + 5

y = 9.5

**Given:**

The vertices of a parallelogram GHJK are K(1,2), J(5,2), G(0,8).

**To find:**

The coordinate of the vertex H.

**Solution:**

We know that the diagonals of a parallelogram bisects each other. It means the midpoint of the diagonals are same.

Let the coordinate of the vertex H are (a,b).

Midpoint formula:

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

In parallelogram GHJK ,

Midpoint of diagonal GJ = Midpoint of diagonal HK

[tex]\left(\dfrac{0+5}{2},\dfrac{8+2}{2}\right)=\left(\dfrac{a+1}{2},\dfrac{b+2}{2}\right)[/tex]

[tex]\left(\dfrac{5}{2},\dfrac{10}{2}\right)=\left(\dfrac{a+1}{2},\dfrac{b+2}{2}\right)[/tex]

On comparing both sides, we get

[tex]\dfrac{5}{2}=\dfrac{a+1}{2}[/tex]

[tex]5=a+1[/tex]

[tex]5-1=a[/tex]

[tex]4=a[/tex]

And,

[tex]\dfrac{10}{2}=\dfrac{b+2}{2}[/tex]

[tex]10=b+2[/tex]

[tex]10-2=b[/tex]

[tex]8=b[/tex]

**Therefore, the coordinates of the vertex H are (4,8). Hence, option B is correct.**

Naneth deposited php1. 200in a savings account that pays 4%interest in 1 year. How much interest will her money earn in a year?

Estimate the circumference of the circular base of the object. Round to the nearest hundredth if necessary.

circumference: ___ in.

**Answer:**

4.09

**Step-by-step explanation:**

Circumference=

*[tex]2\pi \times r[/tex]*

The **circumference **of the **circular **base of the object is 4.082 in

The **circumference **is the length of any great circle, the **intersection **of the sphere with any plane passing through its center.

Given that, we need to find the **circumference **of the **circular **base of the object, whose **radius **is 0.5 in

The circular object is referred as circle, the circle's **circumference **is its boundary length measured in unit whose power is always 1, like m, cm, km etc.

Here, if we calculate the **circumference **of the object, we will get,

The **circumference **of any circular object given by :-

C = 2π×radius

C = 2×3.14×0.65 = 4.082 in

Hence, the **circumference **of the **circular **base of the object is 4.082 in
