8 more than 2 times a number is 29.

Answers

Answer 1

the answer is 10.5 because the equation is 2x+8=29

Answer 2

Answer:

X = 21/2 = 10 1/2 or 10.5

Step-by-step explanation:

2x + 8:= 29

-8. -8

At a farmer’s market, two vendors sell fresh milk. One vendor sells 2 liters for $3.80, and another vendor sells 1.5 liters for $2.70. Which is the better deal? Explain your reasoning.

Answers

Answer:
The second dealer is better.
Step-by-step explanation:
To figure this out we need to divide the price by the amount of milk. Lets do both at the same time.
3.8/2= 2.7/1.5=
3.8/2=1.9 2.7/1.5=1.8
The second dealer is better.

Answer:

The second vendor because when you purchase 6 liters, it costs less to get it from the second vednor.

Step-by-step explanation:

Compare the price at 6 liters.

3.80(3)= $11.40

$2.70(4)= $10.80

2. Sarah has some blue marbles, twice as many red marbles as blue, and 8 yellow marbles. If she has a total of 32 marbles, how
many red marbles does she have?
A.8
B.12
C.16
D.24

Answers

Given:

Number of blue marbles, twice as many red marbles as blue, and 8 yellow marbles.

She has a total of 32 marbles.

To find:

The number of red marbles.

Solution:

Let number of blue marbles be x.

Then, number of red marbles = 2x

Number of yellow marbles = 8

Total number of marbles = 32

[tex]x+2x+8=32[/tex]

[tex]3x=32-8[/tex]

[tex]3x=24[/tex]

[tex]x=8[/tex]

Now,

Number of red marbles [tex]=2(8)=16[/tex]

Therefore, there are 16 red marbles.

What value of x satisfies this equation? log(5x+20)=2

Answers

Answer:

Step-by-step explanation:

Given expression:

log(5x + 20) = 2

From the given expression, we are to find x;

Using the rule of logarithm, we can solve this problem;

logₐb = C

b = Cᵃ

So;

log(5x + 20) = 2

this is to base 10;

5x + 20 = 10²

5x = 100 - 20

5x = 80

x = 16

16 was right

The total number of ways to select 5 out of 10 will be;

10 C 5 = 252

The number of ways of selecting 2 boys out of 6 will be

6 C 2 = 15 ways

The number of ways of selecting 3 girls out of 4 will be

4 C 3 = 4 ways

The probability of both will be;

(4 * 15)/252 = 60/252 = 0.238095238095

To the nearest percentage, that will be 23.81%

Which description of the graph of y=110x is most accurate?

The graph is a line that rises steeply from left to right and passes through the origin.

The graph is a line that rises gradually from left to right and passes through the origin.

The graph is a line that falls gradually from left to right and passes through the origin.

I don't know.

Answers

Answer:

The correct option is;

The graph is a line that rises steeply from left to right and passes through the origin

Step-by-step explanation:

The given equation is y = 110·x

Comparing the given equation to the general equation of a straight line, y = m·x + c

Where;

m = The slope of the straight line graph

c = The y-intercept

We have;

The slope of the given equation, y = 110·x = 110

The y-intercept, which is given by the constant c in the given equation = (0, 0)

Therefore, by the slope of the equation, for each unit increase in x, y increases by 110, therefore, the graph is a straight line that rises steeply and passes through the origin

The true option is (2) The graph is a line that rises gradually from left to right and passes through the origin.

The linear function is given as:

y = 110x

A linear function that passes through the origin has the form y = mx.

This means that:

m = 110

When m > 0, then the line of the graph rises from left to right.

Hence, the true option is (2)

If a roof is 24 feet high and if you leaned a 26 foot ladder against the side of a building how far away from the building is the base of a ladder to reach the roof

Answers

Answer: 35.4 feet.

Step-by-step explanation:

Given data:

Height of the roof = 24 feet

Height of the ladder = 26 foot

Solution:

c^2 = a^2 + b^2

a = 24

b = 26

c^2 = 24^2 + 26^2

c = √576 + 676

c = √1252

c = 35.4 feet

The foot of the ladder is 35.4 foot away from the top of the ladder.

Answer:

The distance between the base of the ladder and the building is 10 ft

Step-by-step explanation:

Here, we want to calculate the distance between the foot of the ladder and the building

To get this, we need to have a pictorial representation. Please check the attachment for this

From the pictorial representation, we can see a right angled triangle with a hypotenuse of 26 feet and the other side being 24 feet. We now need to get the third side of this triangle which represents the distance we want.

Mathematically, we can calculate the distance using Pythagoras’ theorem which states that the square of the length of the hypotenuse is equal the sum of the squares of the two other sides of the triangle.

Let the distance we are looking for be D

26^2 = 24^2 + D^2

D^2 = 26^2 - 24^2

D^2 = 100

D^2 = 10^2

D = 10 feet

The number is

Answers

Question (rewritten into a easier form): x¹⁰ ÷ x⁷ = 512

Answer:

Using our knowledge that x¹⁰ ÷ x⁷ = x³, we can rewrite the equation as:

x³ = 512

To work out what x is, we do ∛512 (cubed root of 512).

This will get us: 8.

Final answer:

The number is 8.

Proof:

8¹⁰ = 1073741824
8⁷ = 2097152

1073741824 ÷ 2097152 = 512

Ram buys an article for $ 1800 and sells it at 10% loss. Find its selling price. *

Answers

Answer:

The answer is $180

Step-by-step explanation:

10% = 0.10

.10 x 1800 = 180

Answer:

cost price ( cp) =$ 1800

loss = 10%

selling price ( sp) = ?

we know,

sp= cp - loss percent of cp

= 1800- 10/100 × 1800

= 1800 - 0.1× 1800

= 1800-180

=$1620
