The two given triangles are congruent because of SAS.
What does congruency mean?In geometry, two figures or objects are congruent if their shapes and sizes match, or if one is the mirror image of the other. Both of the bread slices have the same shape and size when stacked on top of the other. Congruent refers to having the same precise size and shape. Having the same size and shape makes two shapes congruent. The mirror image of one shape is the same as the other if the two shapes are congruent.
The given triangles are RTP and STP
P is the midpoint of RS and TP is the altitude of triangle RTS.
In the triangles RTP and STP
TP = TP (common)
∠RPT = ∠ SPT (90°)
RP = SP (median divides the side equally)
So, both triangles are congruent using SAS property.

He multiplies the denominator by 7.
Step-by-step explanation:
8 wholes and one eighth divided by five sixths
Answers
The expression is:
[tex]8\frac{1}{8}/\frac{5}{6}[/tex]To divide this quantities, first we need to convert 8 and 1/8 to a fraction.
We do this as follows:
[tex]8\frac{1}{8}=\frac{8\times8+1}{8}=\frac{64+1}{8}=\frac{65}{8}[/tex]As you can see, to make the conversion we multiply the whole number by the denomitar and add the numerator (8x8+1) and divide by the same denominator.
So the division to make is:
[tex]\frac{65}{8}/\frac{5}{6}[/tex]A division between two fractions is made as follows:
So applying this to our division we get:
[tex]\frac{65}{8}/\frac{5}{6}=\frac{65\times6}{8\times5}=\frac{390}{40}=\frac{39}{4}[/tex]The answer is: 39/4, which represented as a mixed fraction is:
[tex]\frac{39}{4}=9\frac{3}{4}[/tex]Triangle A B C is shown. Side A C has a length of 27. Side C B has a length of 54.
Based on the diagram, which expresses all possible lengths of segment AB?
AB = 25
27 < AB < 81
AB = 85
AB< 27 or AB > 81
Answers
The possible length of segment AB is 27 < AB < 81
From the question, we have
In triangle ABC
AC = 27
CB = 54
Using Pythagoras theorem,
AC² = AB² + CB²
54² = AB² + 27²
AB = 47
The possible length of segment AB is 27 < AB < 81
Multiplication:
To determine the sum of two or more numbers, mathematicians multiply the numbers. It is a basic mathematical procedure that is widely used in daily life. Multiplication is used when we need to mix groups of like sizes. Multiplication is a representation of the underlying idea of adding the same number repeatedly. The outcome of multiplying two or more numbers is referred to as the product of those numbers, and the factors are the quantities that are multiplied. Multiplying the numbers makes it simpler to add the same number repeatedly.

let the length of the rectangle be L and the width be w, so that
L = 3 + 2w
Also perimeter = 2 ( L + w)
2( L + W) = 30

The value of f(4) is 1125.
Here,
we have given the value of f(1)=9 and f(n)=5f(n-1) and we have to find out the value of f(4).
From the above equation of f(n), it is clear that for finding value of f(4) we have to find value of f(3).
And for f(3) we have to find out the value of f(2)
So,
first, we will find out value of f(2) and then eventually value of f(3) and f(4) by using the given formula of f(n)
The given formula for f(n) is
f(n)=5f(n-1)
So,
f(2)=5f(2-1)
f(2)=5f(1)
f(2)=5×9
f(2)=45
Now,
f(3)=5f(3-1)
f(3)=5f(2)
f(3)=5×45
f(3)=225
And,
f(4)=5f(4-1)
f(4)=5f(3)
f(4)=5×225
f(4)=1125

lenght=177
width= 46
Step-by-step explanation:
l= lenght w=widht
l= 4*w -7
perimeter= 2l+2w = 446
so:
2(4*w -7)+2w=446
8w-14+2w=446
10w=460
w=46
and
l=4*46-7
l= 177
Answer:
Explanation:
To find the dimensions of the playing field, let's assign variables. Let's say the width of the field is "w" yards.
According to the problem, the length of the field is 7 yards less than quadruple the width. This can be written as:
Length = 4w - 7
The perimeter of a rectangle is the sum of all its sides. In this case, the perimeter is given as 446 yards.
The formula for the perimeter of a rectangle is:
Perimeter = 2(Length + Width)
Substituting the given values, we get:
446 = 2(4w - 7 + w)
Now, let's solve the equation step-by-step to find the value of "w" and then find the dimensions of the field.
1. Distribute 2 to the terms inside the parentheses:
446 = 2(5w - 7)
2. Simplify the expression inside the parentheses:
446 = 10w - 14
3. Move -14 to the other side of the equation:
446 + 14 = 10w
4. Combine like terms:
460 = 10w
5. Divide both sides of the equation by 10:
46 = w
Now that we have the value of "w", we can find the length of the field by substituting it into the equation for the length:
Length = 4w - 7
Length = 4(46) - 7
Length = 184 - 7
Length = 177 yards
Therefore, the dimensions of the playing field are:
Width = 46 yards.
Length = 177 yards.

What is Percentage?
A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent symbol, "%," is frequently used to indicate it. A % is a number without dimensions and without a measurement system.
Bob's price dropped by $0.30, or BLANK, between April 1 and May 1.
Considering that the initial price was $3.20, the percentage change was 0.3/3.2, or 9.37%.
Bob's cost grew by $0.30 between May 1 and June 1 (or BLANK).
Price change was -0.3/3.5 = -8.57% since the initial price was $3.50.
Consider that the prices at the gas station across the street are consistently 20% more than those at Bob's. When gas costs $3.50 instead of $3.20, the price difference between Bob's and the prices across the street is BLANK in absolute terms.
Since 20% of $3.50 is greater than 20% of $3.20, the absolute difference will be greater when gas costs $3.50.
Let's say the Federal Reserve increases the federal funds rate objective from 2% to 2.5%. The Fed increased its target by almost BLANK percentage points as a result of this change.
