Answer:

1/8

Step-by-step explanation:

Imagine the value of all of the t-shirts are equal to 1.

3/5 of all of them are blue, so 3/5 of 1 --> 3/5 * 1 =3/5

5/8 of the blue tshirts are on sale, so 5/8 of 3/5 --> 5/8 * 3/5 = 3/8

1/3 of those tshirts are medium, so 1/3 of 3/8 --> 1/3 * 3/8 = 1/8

So, 1/8 of all of the tshirts are blue, on sale, and medium

The fraction of the shop's T-shirts that are blue, on sale, and size medium is 1/8.

To find the fraction of the shop's T-shirts that are blue, on sale, and size medium,  multiply the fractions representing each condition.

Given:

Three-fifths (3/5) of the T-shirts in the shop are blue.

Five-eighths (5/8) of the blue T-shirts are on sale.

One-third (1/3) of the blue T-shirts on sale are size medium.

To find the fraction of blue T-shirts that are on sale,  multiply the fractions representing each condition:

(3/5) * (5/8) = 15/40 = 3/8

This means that 3/8 of the blue T-shirts are on sale.

To find the fraction of blue T-shirts that are on sale and size medium, multiply this result by the fraction representing the size medium condition:

(3/8) * (1/3) = 3/24 = 1/8

Therefore, the fraction of the shop's T-shirts that are blue, on sale, and size medium is 1/8.

Answer:

You cannot add like terms like that.

Step-by-step explanation:

The terms are supposed to be added together, by combining them like that you are multiplying them together.

Answer:

Step-by-step explanation:

There are many ways to solve this:

- factorising

- formula

- perfect squaring

FACTORISING:

The first step would be to multiple the coefficient of x^2 and 6.

Then find which of the factors of 6 sum up to 5. (In this case it is 2 and 3.)

So you would rewrite the equation like this:

x2 -3x -2x + 6 = 0

Then factorise

x(x-3) - 2(x-3) = 0

Then factorise again

(x-2)(x-3) = 0

So if we were to divide each side by (x-2)

(x-3) =0

so x = 3

OR

if we were to divide each side by (x-3)

(x-2) = 0

x = 2

FORMULA:

The formula is

-b±[tex]{\sqrt{b^2 -4ac}[/tex] / 2a

where

ax^2 + bx + c = 0

The first step would be to substitute.

PERFECT SQUARING:

The first step would be to half the second term.

[tex](x - \frac{5}{2})^{2} - \frac{25}{4} - 6 = 0[/tex]

Then solve for x.

Answer:

r=12.5 units

Step-by-step explanation:

Well assuming that DM means diameter of a circle, then r should be the radius of the circle.

Diameter of a circle is twice the radius of the circle, hence with the value of Diameter, you should half it to get the value of radius.

Given  diameter =25

Radius will be= 25/2 = 12.5 units

The value of r is 12.

This is because the line segment DM is made up of two segments, DG and GM.

We are given that the length of DM is 25, and the lengths of DG and GM are r+2 and 2r-13, respectively.

Therefore, we can set up the following equation:

r+2 + 2r-13 = 25

Combining like terms, we get:

3r - 11 = 25

Adding 11 to both sides, we get:

3r = 36

Dividing both sides by 3, we get:

r = 12

Therefore, the value of r is 12.

Question

Answer:

B. 62°

Step-by-step explanation:

According to the Supplementary Angles Theorem, in this case, ∠s and 152° form a straight angle, so you use the Supplementary Angles Theorem:

-152° + 180 = 28°; 28° = m∠s

Then, use the Triangular Interior Angles Theorem to find the m∠t:

28° + 90° = 118°

↑

∠s

-118° + 180° = 62°; 62° = m∠t

I am joyous to assist you anytime.

Answer:  Option 'b' is correct.

Step-by-step explanation:

Since we have given that

Measure of exterior angle = 152°

and measure of one opposite interior angle = 90°

Measure of another opposite interior angle be 't'.

As we know that

Sum of interior angle is equal to exterior angle.

[tex]90^\circ+t=152^\circ\\\\t=152^\circ-90^\circ\\\\t=62^\circ[/tex]

Hence, the measure of t is 62°.

Therefore, Option 'b' is correct.

Answer:

$173.90

Step-by-step explanation:

The most obvious way to answer this question is to multiply $9.40 by 18.5

This would result in 173.90.

But I realize nobody like to deal with decimals in a multiplication problem, so here's the way I would do it (especially if you don't have a calculator!)

The strategy is to break it down!

Multiply $9.40 x 18 hours to start, since this is easier.

[tex]9.4 x 18 = 169.2[/tex]

So, that's $169.20 for 18 hours of work.

We aren't finished, because Abdel worked for 18.5 hours.

So, what half of $9.40?

[tex]9.4 / 2[/tex]

= 4.7

-or-

$4.70

So, knowing that Abdel makes $4.70 in half an hour, lets just add that onto the $169.20 we got earlier.

169.2 + 4.7 = 173.9

-or-

$173.90 for 18.5 hours of work!

Final answer:

To solve the system of equations, we determined the number of hotdogs sold as 'h' and found out that the vendor sold 57 hotdogs and 171 sodas.

Explanation:

The problem given is a system of equations question where we need to find the number of sodas and hotdogs sold by a vendor when given the total sales and the ratio of sodas to hotdogs. To solve this, we'll denote the number of hot dogs sold as 'h' and the number of sodas sold as 's'. According to the problem, the total number of items sold is 228, which gives us the equation:

s + h = 228.

It's also given that the number of sodas sold is three times the number of hot dogs sold. This is our second equation:

s = 3h.

Now we can substitute the second equation into the first, yielding:

3h + h = 228,

which simplifies to:

4h = 228.

Dividing both sides by 4 gives:

h = 57.

With the knowledge that h = 57, we use s = 3h to find that:

s = 3 × 57,

s = 171.

Therefore, the vendor sold 57 hotdogs and 171 sodas.

Whenever you take the square root of a number you get a negative and a positive result: √ 4 = ± 2 or { − 2 , 2 } − 2 ⋅ − 2 = 4 and 2 × 2 = 4

The two square roots of 4 are 2 and -2.

The factor of a number that, when multiplied by itself, yields the original number is known as the square root of the number. Special exponents include squares and square roots. Think about the number 9. When the number 3 is multiplied by itself, the result is 9. This can be expressed as either 3² or 3 × 3.

Given:

The number is 4,

Factorize the number as shown below,

4 = 2 × 2

Calculate the value of the square root of 4 as shown below,

√4 = √(2 × 2)

√4 = ±2

√4 =  2 or -2

Check as:

-2 × -2 = 4

2 × 2 = 4

Answer:

The cost of the doll is $11.75

Step-by-step explanation:

Let

x ----> the cost of the doll

y ----> the cost of the toy t-rex

we know that

[tex]x+y=33[/tex] -----> equation A

[tex]y=x+9.50[/tex] ----> equation B

substitute equation B in equation A and solve for x

[tex]x+(x+9.50)=33\\2x+9.50=33\\2x=33-9.50\\2x=23.50\\x=\$11.75[/tex]

therefore

The cost of the doll is $11.75

Answer:

Doll cost = $11.75.

Step-by-step explanation:

Given  :A doll and a toy t-rex cost $33 together. If the t-rex toy costs $9.50 more than the doll.

To find :   how much did the doll cost.

Solution : We have given

A doll and a toy t-rex cost $33 together.

Let the Doll cost = x .

According to question .

t-rex toy costs $9.50 more than the doll.

T-rex cost = $9.50+ x .

Then, A doll and a toy t-rex cost $33 together.

Doll cost + T oy t-rex cost =  $33

Plugging the values

x +  $9.50+ x  =$33 .

2x + $9.50 =$33 .

On subtracting both sides by $9.50

2x =33 - 9.50

2x = 23.5.

On dividing both sides b y 2

x = $11.75

Doll cost  =$11.75

Toy Cost = 9.50 +11.75.

Toy Cost = $21.25

Therefore, Doll cost = $11.75.
