Here is the working on this question.
Answer: Choice D) 13 inches

===========================================

Work Shown:

C = circumference = 40 inches

d = diameter

[tex]C = \pi*d\\\\C \approx 3.14*d\\\\40 \approx 3.14*d\\\\\frac{40}{3.14} \approx d\\\\d \approx \frac{40}{3.14}\\\\d \approx 12.73885\\\\d \approx 13\\\\[/tex]

Be careful. Technically 12 inches is the largest diameter Tanya can use since 3.14*12 = 37.68 is under 40; while 3.14*13 = 40.82 is slightly over 40

So if I was the teacher, I would have said "round down to the nearest inch".

Using exponential functions, the ending balances are given as follows:

1. $1,490.07.

2. $1,073.83.

3. $358.04.

What is an exponential function?

An increasing exponential function is modeled by:

[tex]A(t) = A(0)(1 + r)^t[/tex]

In which:

A(0) is the initial value.r is the growth rate, as a decimal.

Item a:

The parameters are:

A(0) = 939, r = 0.08, t = 6.

Hence the balance is:

[tex]A(6) = 939(1.08)^6 = 1490.07[/tex]

Item b:

The parameters are:

A(0) = 823, r = 0.03, t = 9.

Hence the balance is:

Item c:

The parameters are:

A(0) = 269, r = 0.1, t = 3.

Hence the balance is:

Answers

Answer:

38 degrees

Step-by-step explanation:

Since angles KLO and OLM are supplementary, they add up to 180 degrees

So,  angle OLM is 180-134=46 degrees

Similarly, angles OMN and OML are supplementary, so they also add up to 180 degrees

So, angle OML is 180-84=96 degrees

You also know that the angles of a triangle sum up to 180 degrees

So, 46+96+x=180

180-142=38

x=38 degrees

Angles on a straight line sum up to 180degrees
So 180-134= 46 and 180-84=96
So interior angles of a triangle sum up to 180
Hence x + 46 + 96 =180
X+142=180
X= 180-142
X=38

Step-by-step explanation:

x needs to be equal or less than 3. It doesn't say that x cannot be negative so any number 3 and below is fine.

Not solutions would be any number above 3 in value

The three solutions for the inequality are 1, 2, and 3.

And, the three numbers that are not solutions are 4, 5, and 6.

Used the concept of inequality that states,

A relation by which we can compare two or more mathematical expressions is called an inequality.

Given that,

The inequality is,

x ≤ 3

Now from the given inequality x ≤ 3,

The solution of the inequality is a number that is less or equal to 3.

Hence the possible three solutions for the inequality are,

x = 1, 2, 3

And, the three numbers that are not solutions are,

Answers

Answer:

(8,1) (15,2) (22,3) (29,4) (36,5) (43,6)

Step-by-step explanation:

Answer:

Step-by-step explanation:

The equation y=7x+1 is written in slope intercept form. That would be:

y=mx+b

m is the slope

b is the y intercept, or where the line first is seen on the y axis.

Because b=1, the y intercept is 1.

Because m=7, the slope is 7.

STEP 1: GRAPH THE Y INTERCEPT.

Since b=1, the line crosses the y intercept when y=1. So graph y=1 on the coordinate plane.

STEP 2: GRAPH THE SLOPE

Do this by going up 7, then right 1. Because 7 is a positive number, you go up.

7 1/2% of $79.50 - $5.60

Total commission earned $828.80

Hope this helps!
you can do this two ways by either finding the total for all his sales then get his commision or find commision per machine then multiply by amount of machines sold. it doesnt matter just depends on pref. so imma do the first one

79.5 x 148 =11766
11766 x .075(commision) =882.45

We have proven that ΔACO ≅ ΔBDO using the SAS (Side-angle-side) theorem

Congruent triangles

From the question, we are to prove that ΔACO ≅ ΔBDO

From one of the congruent triangles theorem, we have that

If two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.

This is the SAS (Side-angle-side) theorem.

From the given information,

AB and CD intersect at point O

Thus, AO = BO

Also,

∠ACO ≅ ∠BDO

In the diagram, we can as well observe that CO ≅ DO

Thus, we can conclude that AC ≅ BD

Since sides AC, CO and the included angle ACO are congruent to sides BD, DO and the included angle BDO, we can conclude that ΔACO ≅ ΔBDO using the SAS theorem.

Hence, we have proven that ΔACO ≅ ΔBDO

[tex]\sf a. \quad \dfrac{21}{10+x}+\dfrac{21}{10-x}=5[/tex]

Step-by-step explanation:

Formula for calculating speed:

[tex]\boxed{\sf Speed=\dfrac{Distance}{Time}}[/tex]

Therefore:

[tex]\boxed{\sf Time=\dfrac{Distance}{Speed}}[/tex]

Given values:

x = the current (in mph)Speed = 10 mphDistance = 21 milesTotal time = 5 hours

If the boat is traveling downstream, the current (x mph) will be pushing the boat faster, and so the boat's speed will increase by x mph.

Therefore, the expression for the time it takes for the boat to travel downstream is:

[tex]\sf Time\:(downstream)=\dfrac{21}{10+x}[/tex]

If the boat is traveling upstream, the current (x mph) will be pushing against the boat and so the boat's speed will decrease by x mph.

Therefore, the expression for the time it takes for the boat to travel upstream is:

[tex]\sf Time\:(upstream)=\dfrac{21}{10-x}[/tex]

Therefore, if the total time it takes to travel downstream and upstream is 5 hours:

[tex]\implies \sf \dfrac{21}{10+x}+\dfrac{21}{10-x}=5[/tex]

To solve for x:

[tex]\implies \sf \dfrac{21}{10+x}+\dfrac{21}{10-x}=5[/tex]

[tex]\implies \sf \dfrac{21(10-x)}{(10+x)(10-x)}+\dfrac{21(10+x)}{(10-x)(10+x)}=5[/tex]

[tex]\implies \sf \dfrac{21(10-x)+21(10+x)}{(10+x)(10-x)}=5[/tex]

[tex]\implies \sf21(10-x)+21(10+x)=5(10+x)(10-x)[/tex]

[tex]\implies \sf 210-21x+210+21x=5(100-10x+10x-x^2)[/tex]

[tex]\implies \sf 420=500-5x^2[/tex]

[tex]\implies \sf 5x^2=80[/tex]

[tex]\implies \sf x^2=16[/tex]

[tex]\implies \sf x=\pm4[/tex]

Therefore, the rate of the current is 4 mph.

How much does it cost her to make 1 cookie? Round to the tenth place if necessary.

Answers

Answer:

13 dollars and 44 cents, 56 cents.

Step-by-step explanation:

134 dollars are 40 cents = 134.4 dollars.

10b = 134.4

b = 13.44

13 dollars and 44 cents

There are 24 cookies to a batch

24c = 13.44

c = 0.56.

so each cookie costs 56 cents

Answer:

13.44 to make 1 batch. 0.56 to make 1 cookie.

Step-by-step explanation:

If it cost 134.40 to make 10 batches, then you would divide that by 10 for how much it cost for 1 batch.

Then, 1 batch of 24 costs 13.44, you would divide it by 24 for the cost of 1 cookie.

d.  3x + 6 = 26

Step-by-step explanation:

Definitions

Integer:  a whole number that can be positive, negative or zero.
e.g. ..., -3, -2, -1, 0, 1, 2, 3, ...Even number: an integer that is exactly divisible by two.  For example, 2, 4, 6, 8 are all positive even numbers.Consecutive: following one after the other in order.

The sum of three consecutive even integers

Let x be the first even integer.

As there is a difference of 2 between consecutive even integers, the next even integer after x will be (x + 2).

Therefore, the next even integer after (x + 2) will be (x + 2) + 2 = (x + 4).

So "the sum of three consecutive even integers is twenty-six" is:

x + (x + 2) + (x + 4) = 26

To solve

⇒ x + (x + 2) + (x + 4) = 26

⇒ x + x + 2 + x + 4 = 26

3x + 6 = 26

(Please note that there are no three consecutive even integers that sum to 26, so the problem cannot be solved).
