Answer:
24
Step-by-step explanation:
To find the side length of a square, you have to divide the perimeter by 4 (since a square has 4 sides). 28 divided by 4 is 7 and 20 divided by 4 is 5. to find the area of each square, you have to multiply each side length by two. 7 times 7 is 49 and 5 times 5 is 25. 49 minus 25 is 24.
Can someone please solve this it's very important thank you
Angel uses 1/8 cup of sugar for 1/3 of a recipe. How much sugar is needed if Angel makes the entire recipe twice?
plz tell me the steps
Answer:
3/4 cups
Step-by-step explanation:
1/8 for 1/3 refipe
1/8 * 3 = 3/8
3/8 for 1 whole recipe
3/8 * 2 = 6/8 = 3/4
3/4 for 2 whole recipes
Rank the following in order from most precise to least precise.
1500 grams
8.43 inches
1580 meters
5.426 seconds
Answer:
1st most = 8.43 inches
2nd most = 5,426 Seconds
3rd most = 1580 meters
4th most = 1500 grams
Step-by-step explanation:
8.43 inches = 0.7025 feet is most precise as it rounded to 0.7 feet it wouldn't be precise enough.
5,426 Seconds = 01:30:26. hrs mins sec can be converted.
1580 meters = 1.58 km = 158000cm hasn't been properly converted as zeros get lost.
1500 grams = 1.5kg hasn't been precisely converted as zeros get lost.

The vertices of a triangle are (-1,3) (6,3) and (-1,-4)
Find the area of the triangle
Please show all workings
Answer:
24.5 unit²
Step-by-step explanation:
Area of ∆
= ½ | x₁(y₂ - y₃) + x₂(y₃ - y₁) + x₃(y₁ - y₂) |
= ½ | (-1)(3 -(-4)) + 6(-4 -3) + (-1)(3 - 3) |
= ½ | -7 - 42 |
= ½ | - 49 |
= ½ (49)
= 24.5 unit²
Method 2:
Let the vertices are A, B and C. Using distance formula:
AB = √(-1-6)² + (3-3)² = 7
BC = √(-6-1)² + (-4-3)² = 7√2
AC = √(-1-(-1))² + (4-(-3))² = 7
Semi-perimeter = (7+7+7√2)/2
= (14+7√2)/2
Using herons formula:
Area = √s(s - a)(s - b)(s - c)
here,
s = semi-perimeter = (14 + 7√2)/2
s - a = S - AB = (14+7√2)/2 - 7 = (7 + √2)/2
s - b = (14+7√2)/2 - 7√2 = (14 - 7√2)/2
s - c = (14+7√2)/2 - 7 = (7 + √2)/2
Hence, on solving for area using herons formula, area = 49/2 = 24.5 unit²
Answer:
24.5
Step-by-step explanation:
To find the area with the coordinates provided:
(-1,3), (6,3), (-1,-4)
First we count the units that are inside the triangle which is area.
[tex]\frac{49}{2}[/tex]
So we know that there are [tex]\frac{49}{2}[/tex] units and then we divide 49 by 2 which gets you 24.5.
49 ÷ 2 = 24.5
The answer is 24.5 units.

How many deli sandwiches did she make?
Please help me.
Answer: 6 sandwiches
Step-by-step explanation:
To get the amount of roast beef that Marissa used you would have to subtract 2 3/4 from 5...which is 2.25 pounds of beef that she used.
Then you would divide 2.25 by 3/8 which is 6... meaning Marisa made 6 sandwiches!
In the following equation, what number represents the y-intercept?

Plz hurryThe center of circle Q has coordinates Q(6,-4) . If circle Q passes through R(14,2) , what is the length of its diameter?
Answer:
the diameter is twice the circle radius, or 20
Step-by-step explanation:
Recall that the radius is half the diameter <=> the diameter is twice the radius. In this problem we need to find the radius first, then multiply it by 2 to obtain the diameter.
We need to determine the distance between the center of the circle Q(6, -4) and the point R(14, 2) on the circle.
The Pythagorean Theorem applies here. Going from Q to R, x changes from 6 to 14, or 8 units, which is the horizontal leg of a right triangle, and y changes from -4 to 2, or 6 units. Thus, according to the Pythagorean Theorem, the length of the hypotenuse of this triangle is
r = √(6² + 8²) = √100 = 10
and so the diameter is twice that, or 20.
Find the measures of the numbered angles in the kite.
Answer:
1 is 90
2 is 52
Step-by-step explanation:
1 is a right angle so its 90
for 2 angles in a triangle equal to 180
so 180-90-38 is equal to 52
What is measure of the missing angle? HELP
(2x - 7) + ( x + 4) = 90°
2x + x - 7 + 4 = 90°
3x - 3 = 90°
3x = 90 + 3
3x = 93
x = 93/3
x = 31°
▪2x - 7
= (2 . 31) - 7
= 62 - 7
= 55°
▪x + 4
= 31 + 4
= 35°
