Problem 3
Answer: x = 47Explanation: The angles opposite the congruent sides, are congruent angles. We consider these the base angles. This triangle is isosceles.
==================================================
Problem 4
Answer: x = 32Explanation:
Refer to the diagram below. Note how I've added in the variable y and marked another angle as 53 degrees which is one of the base angles of the left triangle. The base angles of the triangle on the right are y degrees each. Also, note the vertical angles both are y.
For the left triangle, the three angles add up to 180 which means we can solve for y to go from 53+53+y = 180 to y = 74
Then the interior angles of the triangle on the right has the three angles (y,y,x) add to 180 as well. So we have y+y+x = 180 which turns into 74+74+x = 180. That solves to x = 32
==================================================
Problem 5
Answer: x = 58Explanation:
Refer to the diagram below. I've added another base angle x, and the angle 90-x is complementary to this. This is because the two pieces must add to 90.
For the triangle on the bottom, the two base angles 74 and 74, add to the third angle 90-x and we would get 180. So we solve 74+74+(90-x) = 180 to get x = 58
Answer:
3. x = 47
4. x = 32
5. x = 58

Find the area of a triangle and semi circle where the diameter is 18 and the height is 14 using 3.14
Answer:
triangle A= 1/2bh
1/2(18)(14)= 126
semi circle 3.14(9)^2 divided by 2 = 127.17
Triangle Area plus semi circle Area = 126+127.17= 253.17
The population P, in millions, of a certain country can be modeled by the function P(t) = 3.98(1.02)t, where t is the number of years after 1990.
Answer:
7.35 Million
Step-by-step explanation:
So you already have the function and all you have to do is find the years.
p(t)=3.98(1.02)^t
I'm thinking that you should find the difference between 2021 and 1990. The answer would be 31 and just substitute that from t.
p(t)=3.98(1.02)^31
From here you would jut plug this function into your calculator and get a final answer of:
7.35 Million

What is the smaller angle formed by the minute and hour hands at 3:30pm?
the angle would be a 90° angle
========================================================
Explanation:
At 3:00 pm, the hour hand is pointed directly at the '3'. At 4:00 pm, the hour hand moves to point directly at the '4'.
Since 3:30 pm is the halfway point of 3:00 pm and 4:00 pm, this must mean the hour hand is halfway between the '3' and '4'.
Each little tiny tickmark on the clock represents 1 minute. From the "3" to "4", we have 5 tickmarks, so half of that is 5/2 = 2.5
The hour hand is pointing to 2.5 minutes after the 15 minute mark, meaning the hour hand is pointing to the 15+2.5 = 17.5 minute mark.
The span of time from 17.5 minutes to 30 minutes is 30-17.5 = 12.5 minutes.
Divide this over 60 minutes and we get 12.5/60 = 125/600 = 5/24
The 5/24 indicates the fractional amount of 360 degrees being taken up by this angle shown.
So, (5/24)*360 = 75 degrees is the angle measure in this diagram.
can someone solve this question plzzzzzzz ill give brainliest
Answer:
17 to 24
25 to 32
Step-by-step explanation:
8-1=7
16-9=7
therefore it means we add 7 on the next number which is 17; to get 24,and also to the next number after 24 which is 25 to get 32
Answer: 17 to 24 then 25 and 32

Hint There is more than one answer to this problem)
Answer: He can buy 12 shooters with $1. 20 red marbles with $1. 300 multicolored marbles.
Step-by-step explanation:
Shooters = 1 dollar is 60 cents
60 divided by 5 = 12
Red = 60 divided by 3
= 20
Multicolored = 60 x 5 because 1 for 5
= 300

Im supposed to find angles for these, and I don't know on how to do that
Answer:
110
Step-by-step explanation:
They are equal to each other.
23x-5= 21x +5
2x = 10
x = 5
21(5) +5 = 110°
23(5) -5 = 110°
So it works. Angles are 110°

A chicken and rice recipe is shown below. Mrs. Hughes would like to make only two-thirds of the recipe. How many cups of each ingredient does Mrs. Hughes need? 2 2/3 cups of chicken broth 1 1/2 cups of chicken 3/4 cups of rice
Answer:
See explanation below
Step-by-step explanation:
This is actually pretty easy to explain, and we all need to do is work with fractions.
So we have a recipe for chicken and rice, but the person decides to use 2/3 of the recipe. to determine the quantity of each ingredient to be used, we just need to multiply the cups of each ingredient by 2/3, and that's it.
Let's go with each ingredient, one by one:
Chicken broth 2 2/3 cups:
In this case, let's convert the 2 2/3 to a simple fraction. (We just multiply the denominator by the single number and then, sum the numerator)
2 2/3 = (3*2) + 2 / 3 = 8/3 of cups
8/3 * 2/3 = 16/9 cups of chicken.
But to do this better, let's convert this into a mix fraction:
16 : 9 = 1 and the rest is 7 so:
1 7/9 cups of chickenChicken 1 1/2 cups:
We'll do the same thing as before:
1 1/2 = (2*1) + 1 / 2 = 3/2 of cups
3/2 * 2/3 = 1
1 cup of chicken3/4 cups or rice:
3/4 * 2/3 = 1/2
1/2 cup of riceHope this helps

solve for y
3x+1/5y=7
Answer:
y = -15x + 35
