what does 10 = 4y equal to

Answers

69 ghcfhhggghjjohufdhhdjc

Answer:

Step-by-step explanation:

Simplifying

10 = 4y

Solving

10 = 4y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-4y' to each side of the equation.

10 + -4y = 4y + -4y

Combine like terms: 4y + -4y = 0

10 + -4y = 0

Add '-10' to each side of the equation.

10 + -10 + -4y = 0 + -10

Combine like terms: 10 + -10 = 0

0 + -4y = 0 + -10

-4y = 0 + -10

Combine like terms: 0 + -10 = -10

-4y = -10

Divide each side by '-4'.

y = 2.5

Simplifying

y = 2.5

An artist builds a sculpture out of metal and wood that weighs 14.9 kilograms. LaTeX: \frac{3}{4}3 4 of this weight is metal, and the rest is wood. How much does the wood part of the sculpture weigh? Enter your number as a mixed number. (no decimals)

Answers

Answer:

3 29/40 kg

Step-by-step explanation:

An artist builds a sculpture out of metal and wood that weighs 14.9 kilograms. LaTeX: \frac{3}{4}3 4 of this weight is metal, and the rest is wood. How much does the wood part of the sculpture weigh? Enter your number as a mixed number. (no decimals)

Step 1

We find the fraction of the sculpture that is wood

Let the Fraction of the sculpture = 1

Fraction of the sculpture that is metal = 3/4

Fraction of the sculpture that is wood =

1 - 3/4

= 1/4

Step 2

How much does the wood part of the sculpture weigh? Enter your number as a mixed number. (no decimals)

This is calculated as:

Weight of the total sculpture × Fraction of the sculpture that is wood

= 14.9 kg × 1/4

= 3 29/40 kg

Rachel bought 15 packs of colored pencils with four pencils in each pack. She also
bought 32 packs of glitter pencils with two pencils in each pack. Write and evaluate an
expression to find the total number of pencils she bought.

Answers

Answer:

124

Step-by-step explanation:

15 x 4=60

32 x 2=64

64+60=124

Rachel bought a total of 124 pencils.

What is a numerical expression?

A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.

To find the total number of colored pencils Rachel bought, you can multiply the number of packs she bought by the number of pencils in each pack. Since she bought 15 packs of colored pencils with four pencils in each pack, the expression would be:

15 packs × 4 pencils/pack = 60 pencils

To find the total number of glitter pencils Rachel bought, you can use the same process. Since she bought 32 packs of glitter pencils with two pencils in each pack, the expression would be:

32 packs × 2 pencils/pack = 64 pencils

To find the total number of pencils Rachel bought in total, you would add the number of colored pencils to the number of glitter pencils. The expression would be:

60 pencils + 64 pencils = 124 pencils

Hence, she bought a total of 124 pencils.

Find the measure of each angle indicated. Round to the nearest tenth.

Answers

Answer:

missing angle = 67.8 degrees

Step-by-step explanation:

[tex]cos-1 = \frac{adjacent}{hypotenuse}[/tex]

[tex]cos-1 = \frac{5.3}{14}[/tex]

[tex]cos-1 = 0.378571428[/tex]

[tex]67.754 = 67.8[/tex]

C) 67.8° is the value of theta in the given right-angled triangle.

What are trigonometric ratios in terms of a right-angle triangle?

We know a right-angled triangle has three sides they are -: Hypotenuse,

Opposite and Adjacent.

We can remember SOH CAH TOA which is,

sin = opposite/hypotenuse, cos = adjecen/hypotenuse and

tan = opposite/adjacent.

Given, a right-angled triangle whose adjacent and hypotenuse are 5.3 and 14 respectively.

We know cos(theta) =  adjacent/hypotenuse.

∴ theta = cos⁻¹(adjacent/hypotenuse).

theta = cos⁻¹(5.3/14).

theta = cos⁻¹(0.3786).

theta = 67.8°.

You buy a new car and it depreciates 6.2% per year in value. If the value of the car can be modeled by V(t)=45,000⋅bt, what would be the value of b?

Answers

Answer:

b = 0.938

Step-by-step explanation:

Value of the car can be modeled by the function,

V(t) = [tex]45000(b)^t[/tex]

Since, formula for the depreciation is modeled by,

V(t) = [tex]V_0(1-\frac{r}{100})^t[/tex]

Here, V(t) = Final value of the car after t years

V(0) = Initial value of the car

r = rate of depreciation

t = Time (in years)

By comparing both the functions which are similar,

[tex]1-\frac{r}{100}=b[/tex]

[tex]1-\frac{6.2}{100}=b[/tex]

b = 1 - 0.062

b = 0.938

A. Y-68=-5(x-14) B. Y+68=5(x+14) C. Y+68=-5(x-14) D. Y+68=5(x-14)

Answers

Answer:

A. Y-68=-5(x-14)

Step-by-step explanation:

Mary is spending money at the average rate of $5 per day. After 14 days she has $68 left. The amount left depends on the number of days that have passed. write an equation for the situation

We find the equation using the point slope equation of a line. This is given as:

y - y1 = m(x-x1)

The slope intercept form will be

y = -5x + b

since the amount decreases by $5 per day...

Our slope is -5 so m=-5

We have a point (x1,y1) = (14, 68)

Hence, we have:

y-68 = -5(x-14)

A fossil contains 19% of the carbon-14 that the organism contained when it was alive. Graphically estimate its age. Use 5700 years for the half-life of carbon-14.
The fossil is approximately _years old.
(Round to the nearest integer as needed.)

Answers

In this specific question, the first thing you should do is to figure out what k is. You can do this by using the fact that the half life of carbon-14 is 5700 years. To find k set up your equation as follows:

.5=e^5700k

To figure out k here take the natural log of both sides:

ln(.5)=5700k

Then solve for k:

k=ln(.5)/5700 ~~ -1.216*10^-4

Now that we know what k is, we can go back to the original question and plug in everything we know! Our new equation should look like this:

.04=e^((ln(.5)/5700)t)

Solving for t works the same as solving for k, take the natural log of both sides:

ln(.04)=(ln(.5)/5700)t

Then solve for t:

t=ln(.04)/(ln(.5)/5700) ~~ 26469.98 years
