write an expression to represent the following situation:10 dollars less than catilian

Answer:

5 cm

Step-by-step explanation:

The rectangle has a length (l) of 7 cm and a width (w) of 3 cm. Therefore, the perimeter of the rectangle is:

Perimeter of rectangle = 2(l + w) = 2(7 + 3) = 2(10) = 20 cm

Since the rectangle and the square has the same perimeter, Therefore, the perimeter of the square is:

Perimeter of square = 2(l + w). But the length and width of a square are the same (i.e l = w). Therefore:

Perimeter of square = 4l

20 = 4l

l = 20 / 4 = 5 cm

Each side of the square has a length of 5 cm

Answer:

Step-by-step explanation:

The only angle we are given directly inside that triangle is angle R, 87 degrees. We can use the fact that the exterior angle at T is 92, so the interior angle is 180 - 92 = 88.  Now we can find angle S: 180 - 87 - 88 = 5. So angle S = 5 degrees. The Law of Sines can be used now to find the length of SR:

[tex]\frac{sin5}{950} =\frac{sin88}{x}[/tex]

Cross multiply to get

x sin5 = 950 sin88 and

[tex]x=\frac{950sin88}{sin5}[/tex] so

x = 10,893 km

Answer:

w=−5

Step-by-step explanation:

Step 1: Subtract 3w from both sides.

7w+5−3w=3w−15−3w

4w+5=−15

Step 2: Subtract 5 from both sides.

4w+5−5=−15−5

4w=−20

Step 3: Divide both sides by 4.

4w4=−204

Answer: w=−5

Hope this helps.

Answer:

w =-5

Step-by-step explanation:

Group the variables and constant on each side

remember that the signs will change while switching the places.

7w-3w=-15-5

4w=-20

divide the coefficient to keep only the variable and find its value

4÷4w= -20÷4

w= -5

therefore w is -5

Answer: [tex]1\dfrac{4}{21}[/tex] .

Step-by-step explanation:

Given problem : [tex]\left(-5\dfrac{5}{6}\right)\div\left(-4\dfrac{9}{10}\right)[/tex]

First we convert mixed fraction into improper fractions as

[tex]-5\dfrac{5}{6}=-\dfrac{5\times6+5}{6}=-\dfrac{30+5}{6}=-\dfrac{35}{6}\\-4\dfrac{9}{10}=-\dfrac{10\times4+9}{10}=-\dfrac{40+9}{10}=-\dfrac{49}{10}[/tex]

Now , plug these values in the given expression , we get

[tex]\left(-5\dfrac{5}{6}\right)\div\left(-4\dfrac{9}{10}\right)=-\dfrac{35}{6}\div\left(-\dfrac{49}{10}\right)\\\\=\dfrac{-35}{6}\times\dfrac{-10}{49}\ \ \ [\text{By Property of fraction}]\\\\=\dfrac{350}{294}\\\\=\dfrac{25}{21}=1\dfrac{4}{21}[/tex]

Hence, the answer is [tex]1\dfrac{4}{21}[/tex] .

Answer: 72.9 in^3

Step-by-step explanation:

The softball is a sphere, and we know that the volume of a sphere is:

V = (4/3)*pi*r^3

where pi = 3.14 and r is the radius.

We also know that the radius is half the diameter, and the diameter is 5.2 in

r = 5.2in/2 = 2.6in

Then the volume is:

V = (4/3)*pi*(2.6in)^3 = 72.9 in^3

The correct answer is 73.6 in^3

[tex]\rule[225]{225}{2}[/tex]

Step-by-step explanation:

9.45

To round up to nearest whole number, we have to see the tenth place.

If the value of the tenth place is greater or equal to 5, then we round up the number to 10. If the value of the tenth place is less than 5, the we round up the number to 9.

The value of the tenth place is 4, which is less than 5, we will round up the number to 9.

[tex]\rule[225]{225}{2}[/tex]

9.45 rounded to the nearest whole number is 9.

Given that a decimal number 9.45 we need to round it to the nearest whole number,

To round a decimal number to the nearest whole number, you need to look at the digit immediately to the right of the decimal point.

In the case of 9.45, the digit to the right of the decimal point is 4. If this digit is less than 5, you simply remove all the digits after the decimal point and keep the whole number as it is.

However, if the digit to the right of the decimal point is 5 or greater, you increase the whole number by 1.

To round 9.45 to the nearest whole number, we examine the decimal part of the number, which is 0.45.

If the decimal part is less than 0.5, we round down to the nearest whole number. In this case, since 0.45 is less than 0.5, we round down.

Therefore, 9.45 rounded to the nearest whole number is 9.

Answer:

Step-by-step explanation:

Let the total amount of the money = x

Therefore:

[tex]\dfrac16x=1.50\\x=1.50 \times 6\\x=\£$ 9[/tex]

Daoud gets 1/2 of the money.

Therefore: Daoud's share of the money

[tex]=\dfrac12 \times \£$ 9 =\£$ 4.50[/tex]

Elsa's Share of the money = 9-(4.50+1.50)=£3

Therefore:

Amount of money Toby gets: Amount of money Elsa gets

= 1.50: 3

Divide both sides by 1.50

Toby's Money : Elsa's Money=1:2

Answer:

Step-by-step explanation:

Answer:

135°

Step-by-step explanation:

total = 360°

360° = 90° + 135° + x°

x° = 360° - (90° + 135°) = 360° - 225°

x° = 135°

Answer:

The lengths are 5, 12, and 13.

Step-by-step explanation:

Let x represent the shorter leg of the triangle. Since the other leg is 7 cm more, the longer leg is x+7. Since the length of the hypotenuse is 3 cm more than double that of the shorter leg, the hypotenuse is 2x+3.

The Pythagorean Theorem may be used to find the lengths.

[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]  a, b are the short and long lengths and c is the hypotenuse

→ [tex]x^{2} + (x+7)^{2} = (2x+3)^{2}[/tex]

→ [tex]x^{2} + x^{2} + 14x + 49 = 4x^{2} + 12x + 9[/tex]

→ [tex]2x^{2} + 14x + 49 = 4x^{2} + 12x + 9[/tex]

→ [tex]2x^{2} - 2x - 40 = 0[/tex]

→ [tex]x^{2} - x - 20 = 0[/tex]

→ [tex](x-5)(x+4) = 0[/tex]

→ [tex]x = 5[/tex] (The length cannot be negative)

The shorter leg, x, is 5 cm. Since the longer leg is x+7, it is 12 cm. Since the length of the hypotenuse is 2x+3, the hypotenuse is 13 cm.

Answer:

30⁰ , 60⁰ , 90⁰

Step-by-step explanation:

Let the angles x , 2x , 3x

By angle sum property:

x + 2x + 3x = 180⁰

6x = 180⁰

x = 30⁰

Angles are : 30⁰ , 60⁰ , 90⁰

Let one angle be x, the second 2x and the third 3x.

x + 2x + 3x = 180 degrees (angle sum property of a triangle)

6x = 180 degrees

x = 180/6

x = 30 degrees

So one angle is 30°, the second is 60°, and the third is 90°.

The greatest common factor of 8m, 36m³, and 12 is 4.

4(2m), 4(9m³), and 4(3).

The HCF is the largest value that divides all three of them.

The greatest common factor of 8m, 36m³, and 12 is; 4.

Greatest common factor, as the name implies, is greatest among all common factors among the quantities given.

We could factorize the quantities in smallest relative factors possible (the level of factors over which all quantities can form themselves), and collect as many common factors as we could.

Factorize the given numbers and identify all common factors. To get the GCF(Greatest common factor) multiply all common factors;

The Common factors are: 2 and 2, their product is 2 x 2=4, then

4(2m) =  2 x 2 x2 x m

4(9m³) =  2 x 2 x3 x3 x m x m x m

4(3) = 2 x 2 x3

Total number of ways to arrage letters = 8!

Number of ways to arrange vowels in alphabetical order = 5!

Then, The number of ways that all the vowels are in alphabetical order will be :

[tex]\dfrac{8!}{5!}=\dfrac{8\times7\times6\times5!}{5!}=336[/tex]

x + y = 34

10*x + 15*y = 410

Step-by-step explanation:

The equation system that models the situation would be made up of two equations:

The first equation would be the total number of hours for both jobs, that is, the number of babysat work hours and the number of yardwork work hours equals 34 total hours.

x + y = 34

The second equation would be the total amount of money earned, in this case it would be to multiply the earnings of each job by the number of hours of each job and add it up and you should give a total of 410 which are your total earnings.

10 * x + 15 * y = 410

Therefore the system of equations would be:

x + y = 34

10 * x + 15 * y = 410

yeah its C

The requried function with the smallest x-intercept value is C. f(x) = √(x+1), which has an x-intercept of -1.

In the equation intercept is the value of the linear function where either of the variables is zero.

Here,
The x-intercept is the point where the graph of a function intersects the x-axis. At this point, the value of y is 0. To find the x-intercept of each function, we set y equal to 0 and solve for x.

A. f(x) = 3x – 9

0 = 3x – 9

3x = 9

x = 3

B. f(x) = 1/x + 4

0 = 1/x + 4

-4 = 1/x

x = -1/4

C. f(x) = √(x+1)

0 = √(x+1)

x = -1

D. f(x) = x²

0 = x²

x = 0

Therefore, the function with the smallest x-intercept value is C. f(x) = √(x+1), which has an x-intercept of -1.
