Answer:
17 and 13
Step-by-step explanation:
So you can set up an equation:
let x be the greater number
this means that the smaller number would be 4 less than x, because their difference is 4, so x - 4.
The sum is 30, so x + (x - 4) = 30
Then, solve:
x + (x - 4) = 30
x + x - 4 = 30
combine like terms
2x - 4 = 30
add 4 to both sides
2x = 34
divide both sides by 2
x= 17
Now you know the greater number is 17. Since they have a difference of 4, you can do 17 - 4 = 13 to get the smaller number.
The numbers are 17 and 13
Mary found a pair of boots that cost $60. Sales tax is 7%. What is the total price Mary will pay for the boots?
Answer: $64.20
Step-by-step explanation:
Cost of shoe = $60
Sales tax rate = 7%
Sale tax = 7% × $60 = 7/100 × 60 = $4.20
The total price paid by Mary
= Cost of shoe + Sales tax
= $60 + $4.20
= $64.20

Step-by-step explanation:
1. c=2piR, so if the radius is 2, then 2 times 2 then times 3.14= 12.6(rounding to the nearest tenth)
2.i already explained the formula, so it should be 3.4*2 then times 3.14= 21.4

In a right angled triangke abc the perpendicular and the base measure 3 cm find hypotenus and three trignometrice ratios
Given:
In a right angled triangle ABC the perpendicular and the base measure 3 cm.
To find:
The hypotenuse and three trigonometric ratios.
Solution:
Pythagoras theorem:
[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]
Use Pythagoras theorem in triangle ABC.
[tex]Hypotenuse^2=(3)^2+(3)^2[/tex]
[tex]Hypotenuse^2=9+9[/tex]
[tex]Hypotenuse=\sqrt{18}[/tex]
[tex]Hypotenuse=3\sqrt{2}[/tex]
The three trigonometric ratios are
[tex]\sin \theta=\dfrac{Perpendicular}{Hypotenuse}[/tex]
[tex]\sin \theta=\dfrac{3}{3\sqrt{2}}[/tex]
[tex]\sin \theta=\dfrac{1}{\sqrt{2}}[/tex]
Similarly,
[tex]\cos \theta=\dfrac{Base}{Hypotenuse}[/tex]
[tex]\cos \theta=\dfrac{3}{3\sqrt{2}}[/tex]
[tex]\cos \theta=\dfrac{1}{\sqrt{2}}[/tex]
And,
[tex]\tan \theta=\dfrac{Perpendicular}{Base}[/tex]
[tex]\tan \theta=\dfrac{3}{3}[/tex]
[tex]\tan \theta=1[/tex]
Therefore, the hypotenuse is [tex]3\sqrt{2}[/tex] cm and three trigonometric ratios are [tex]\sin \theta=\dfrac{1}{\sqrt{2}}, \cos \theta=\dfrac{1}{\sqrt{2}}, \tan \theta=1[/tex].

Find the length of BD for square ABCD.
B
23
A
D
The length of BD is a
(Type an integer or decimal rounded to one decimal place as needed.)
Answer:
BD = 32.5
Step-by-step explanation:
Since this is a square, the length of all the sides are equal. So line AB = BC = CD = DA = 23
Additionally, all the interior angles are the same (90°)
To find the length of BD, you can cut the square in half diagonally to form two right angled triangles, ABD and BCD.
For either one, BD is the hypotenuse of the right angled triangle so we can use Pythagoras' theorem to solve for the that (since we also know the legnth of the sides)
a = 23
b = 23
c = BD, which we have to find
[tex]a^{2} +b^{2} =c^{2} \\23^{2} +23^{2} =c^{2} \\\sqrt{23^{2} +23^{2} } = c\\\sqrt{529+529} =c\\\sqrt{1058} = c\\32.5 = c[/tex]
therefore the length of BD is 32.5
hope this helps!

9) A cow is tethered with a rope 20 ft long. What is the maximum area the cow can graze?
Answer:
If the rope is 20 ft long, then the maximum area the cow can graze is:
[tex]\pi \\[/tex]r^2 square feet.
[tex]\pi[/tex] is approximately 3.14, so that means we have: 3.14(20^2) = 1256 ft squared.
Thus, the maximum area that the cow can graze is 1256 ft squared.
Let me know if this helps!
The cow's maximum grazing area is 1256 ft squared. The grazing area is found as the area of the circle.
What is the area?The space filled by a flat form or the surface of an item is known as the area.
The number of unit squares that cover the surface of a closed-form is the figure's area. Square centimeters and other similar units are used to measure area.
If the rope is 20 feet long, the cow can graze the following area:
A=πr²
A=3.14(20)²
A=1256 ft squared.
As a result, the cow's maximum grazing area is 1256 ft squared.

Emerson struck out 122 times in 350 at bats. What is his percentage of strike outs?
Answer:
Around 35%
Step-by-step explanation:
122/350 = 0.35
Answer:
32%
Step-by-step explanation:
We are told out of 350 times, he stuck out 122 times. As a fraction, we can say he struck out 122/350 times.
As a fraction, we can easily convert this to a decimal by dividing the numerator (top number) by the denominator (bottom number).
So, 122/350 = 0.32.
Now, we can easily convert this to a percentage by multiplying by 100.
0.32 x 100 = 32%
