Which strategy would not correctly solve this story problem? Luke buys a muffin and glass of juice each Monday for breakfast. Each muffin costs $3 and each glass of juice costs $2. How much money will Luke spend for breakfast on 6 Mondays? A. Make a table. Week 1 2 3 4 5 6 Total ($) 5 10 15 20 25 B. Translate into an equation. (3 × 2) + 6 = d C. Use objects to represent the problem. Set out 6 small cups. Use coins to represent dollars. Add $2 + $3 to get the amount spent each Monday ($5). Put that number of coins into each cup. Count the number of coins in the cups. D. Use logical reasoning. In 1 week Luke spent $3 for a muffin plus $2 for juice for a total of $5. So to figure out how much Luke spent in 6 weeks, multiply $5 by 6.

Answer:

1/2

To simplify 12/24 you have to find a common multiple. a common multiple is 12. you see how many times 12 goes into each number. 12/12 is 1 and 24/12 is to. therefore 1/2 is the correct answer

The ratio of multiplication problems to division problems on the given math test is 1/2.

To answer the question, you need to set up a ratio between the number of multiplication problems and the number of division problems. In this case, you have 12 multiplication problems and 24 division problems.

The ratio would be set up as 12 (multiplication problems) to 24 (division problems), written as 12/24 in fractional form. However, we need to reduce this to its simplest form. Both 12 and 24 can be divided by 12, simplifying the ratio to its simplest form of 1/2.

Therefore, the ratio of multiplication problems to division problems on this math test is 1/2.

80 * 80% = 64 So it's not A

80 * 55% = 44 so it's not B

80 * 100% = 80 so it's not C

80 * 125% = 100 so D is your answer

Step-by-step explanation:

Answer:

125%

Step-by-step explanation:

Given,

Responses on first day or original responses = 80

While responses on second day or final responses = 180,

Thus, the percentage increase in the responses

[tex]=\frac{\text{ final responses- original responses}}{\text{original responses}}\times 100[/tex]

[tex]=\frac{180-80}{80}\times 100[/tex]

[tex]=\frac{10000}{80}[/tex]

5x+45=35

Next step--> subtract 45 from 35 to start to get x by itself

5x= -10

Next divide by 5 on both sides so x is by itself to get

x=.  -2

Answer:

x = - 2

Answer:

A

Step-by-step explanation:

Opposite angles of a parallelogram are equal, so z = 96.

Alternate interior angles are congruent, so x = 31.

Angles of a triangle add up to 180, so y = 53.

Based on the parallelogram shown above, the values of the variables are: x = 31°, y = 53°, z = 96°.

In Mathematics, a parallelogram is a type of quadrilateral and two-dimensional geometrical figure that is composed of two equal and parallel opposite sides.

According to the opposite angles theorem, the opposite angles of a parallelogram are always congruent or equal and as such, we have the following:

m∠z = 96°

Based on the alternate interior angles theorem, angles on opposite of a line are congruent;

x = 31°.

Based on angle sum property, we have the following supplementary angles;

x + y + z = 180

31° + y + 96° = 180°

y = 180° - 127°

y = 53°.

Approximately 15% of the computers have viruses.

Answer: Hence, there are 15% of computers have viruses.

Step-by-step explanation:

Since we have given that

Total computers in an office = 500

Number of computers to be inspected = 40

Number of computers had viruses = 6

We need to find the percentage of the computers in the building that have viruses.

So, Percentage of computers in the buildings have viruses is given by

[tex]\dfrac{6}{40}\times 100\\\\=\dfrac{600}{40}\\\\=15\%[/tex]

Hence, there are 15% of computers have viruses.

The confidence interval is at 90%

ii)

The margin of error is 5%

iii)

The 90% confidence interval is (70%, 80%)

iv)

We are 90% confident that the average score of seniors in the field test is between 70% and 80%.

Step-by-step explanation:

i)

The confidence interval is at 90%

We are informed that the exam creator claims that on this particular exam, nine times out of ten, seniors will have an average score within 5% of 75%. This implies that we are 9 times out of 10 confident that seniors will have an average score within 5% of 75%.

The level of confidence is thus;

(9/10)*100 = 90%

ii)

The margin of error is 5% or equivalently 0.05

We are informed that the exam creator claims that on the same exam, nine times out of ten, seniors will have an average score within 5% of 75%.

Since the average score is within 5%, the margin of error is 5%

iii)

A confidence interval is calculated using the formula;

point estimate ± margin of error

Our point estimate is 75%

Our margin of error is 5%

The 90% confidence interval is thus;

75% ± 5% = (70%, 80%)

iv)

The 90% confidence interval is interpreted as;

We are 90% confident that the average score of seniors in the field test is between 70% and 80%.

This is a confidence interval for the mean, the level of confidence is 90% and our confidence interval is (70%, 80%).

Your answer is 7.0

Step-by-step explanation:

If the circles are congruent and RQ measures 35.6, then so does CB.  That means that half of it (the radius XD which measures 26 cuts the length of CB in half) is 17.8.  If the base of that right triangle is 17.8 and the hypotenuse is 26, then Pythagorean's Theorem tells us that the height of the triangle is 18.95151709.  Subtract that from the radius length of 26 and you'll have the length of DE

The value of length ED would be, 7.0

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

Given that;

⊙X≅⊙Y

And, Length of RQ = 35.6

Now, We get;

⇒ CB = RQ = 35.6

Hence, EB = 1/2CB

                 = 1/2 (35.6)

                 = 17.8

Applying Pythagoras theorem,

⇒ XE² = XB² - EB²

⇒ XE² = 26² - 17.8²

⇒ XE² = 19

Thus, The length of ED is,

⇒ ED = XD - XE

⇒ ED = 26 - 19

⇒ ED = 7.0

Therefore, The value of length ED would be, 7.0

[tex]\frac{b^4}{2a^2}[/tex]×[tex]\frac{a}{b^3}[/tex]

Now you can do some canceling out of like terms.  There is a b^3 in the denominator and a b^4 in the numerator.  You can take 3 b's out of 4, so the b^3 cancels completely out with the b^4, leaving only one b behind.  The a in the numerator cancels with one of the a's in the a^2, leaving one behind.  So the answer to this is:

Step-by-step explanation:

Since the triangles are similar then the ratio of corresponding sides are equal, that is

[tex]\frac{4x+12}{15}[/tex] = [tex]\frac{32}{8}[/tex] = 4, thus

4x + 12 = 4 × 15 = 60 ( subtract 12 from both sides )

The system that models the situation is:

[tex]\left \{{{2x + y = 24} \atop {2x - y = 12}} \right.[/tex]

The solution is:

(9, 6)

Step-by-step explanation:

We must write the equations as indicated in the problem.

The sum of twice a number and another number is 24

a number:  x

other number:  y

Then

[tex]2x + y = 24[/tex]

The difference of twice the first number and the other number is 12

first number: x

other number:  y

Then:

[tex]2x - y = 12[/tex]

The system that models the situation is:

[tex]\left \{{{2x + y = 24} \atop {2x - y = 12}} \right.[/tex]

To solve the system we add both equations to find the value of x

[tex]2x + y = 24\\\\2x - y = 12[/tex]

---------------------

[tex]4x +0 = 36\\\\x=\frac{36}{4}\\\\x=9[/tex]

There are 6 faces, so the total surface area would be h^2 x 6

Replace total surface area with 2.16, so you now have:

Answer:

D. Up

Step-by-step explanation:

When a parabola has the form  [tex]y=ax^2+bx+c[/tex] , It is vertical (opens up or down).

Because the variable "x" is squared.

If  "a" is positive, then the parabola opens up, but if it is negative, then the parabola opens down.

In this case you have the quadratic function:

[tex]f(x) = 2x^2+5x-4[/tex]

Which can be rewritten as:

 [tex]y = 2x^2+5x-4[/tex]

Therefore, it is vertical, because it has the form:  [tex]y=ax^2+bx+c[/tex]

You can observe that the value of "a" is:

[tex]a=2[/tex]

Then, since "a" is positive, the parabola opens up.
